It is known that social support is one of the main protective factors in the postpartum period. In addition, studies report the association between biological rhythm disruption and its consequences on health, especially mental, but little is known about the possible causes of this disruption. Thus, the objective of this study was to evaluate the association between the perception of social support and the biological rhythm in women at three months postpartum in the city of Pelotas, Brazil. This is a cross-sectional study nested within a population-based cohort study, using data from an assessment performed 90 to 120 days postpartum. The mother's perception of social support was assessed by the Medical Outcomes Study Social Support Scale (MOS-SSS), while biological rhythm was measured by the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN). Sample composition was based on data from 755 women. After adjusting by linear regression for the potential confounders of schooling and economic class, all domains of social support (material support, affective support, emotional support, informational support and positive social interaction) remained negatively associated with biological rhythm (p < .001). Thus, regression analysis shows for each increment of one point in the domains of social support, there was a decrease between 0,160 and 0,189 points in the maternal biological rhythm. All domains of social support were associated with disruption of the biological rhythm, which reinforces the need for adequate support, especially in a period of many demands, for good maternal health.

ABSTRACT Objective: We evaluated the protective effect of postpartum resilience (measured before the pandemic onset) on the prevalence of moderate to severe anxiety symptoms during the coronavirus disease (COVID-19) pandemic. Methods: The sample included 589 mothers from a longitudinal study in southern Brazil. Three months after delivery we assessed maternal resilience through the Resilience Scale (RS). The Generalized Anxiety Disorders 7-item (GAD-7) was used to assess anxiety symptoms during the COVID-19 pandemic. Results: The prevalence of severe to moderate anxiety symptoms in this sample was 28.4% (95% CI: 25.0; 32.0). Resilience showed to be a protective factor against moderate to severe anxiety symptoms during the pandemic (OR: 0.98; p

BackgroundMicroRNAs (miRNAs) are small non-coding RNAs capable of regulating gene expression post-transcriptionally. MiRNAs are recognized as key regulators of diverse biological and developmental processes. During the pregnancy–puerperal cycle, numerous changes occur in the female body for the formation, growth, and development of the baby. After birth, there is a critical period in child development, as rapid gains in the physical, cognitive, and socio-emotional domains constitute the “building blocks” of children’s later growth.ObjectiveThe aim of this study was to investigate the association between maternal expression of hsa-miR-423-5p during the first and second trimesters of pregnancy and neurocognitive development at 90 days of life in infants. Methods: This is a longitudinal study included in a population-based cohort study, carried out in a city in southern Brazil. The Bayley III was used to assess the babies’ cognitive development. Blood samples from mothers were obtained for RNA extraction from serum and analysis of miRNA expression by qRT-PCR.ResultsIn total, 87 dyads (mother–baby) were included. The average gestational age was 15.86 weeks (SD ± 5.55). An association of maternal miRNA with infant cognitive development was found; as maternal miR-423-5p increases, infants’ cognitive development increases by 2.40 (95% CI 0.37; 4.43, p = 0.021) points at 3 months of age.ConclusionIn this context, it is suggested to use this miRNA as a biomarker of child neurocognitive development detectable in the prenatal period, thus allowing the planning of early interventions.

RESUMO Objetivo: Verificar a prevalência e identificar os fatores associados à ausência do acompanhante de parto em mulheres no sul do Brasil. Métodos: Trata-se de um estudo transversal, realizado com 466 parturientes, pertencentes a uma coorte de mulheres da zona urbana da cidade de Pelotas, RS. Aos 18 meses pós-parto, foi aplicado um questionário estruturado com dados sociodemográficos, gestacionais e questões relacionadas ao parto. Foi realizada regressão logística para ajustes de possíveis fatores de confusão. Resultados: A prevalência da ausência de acompanhante de parto entre as mulheres foi de 22,3%. As parturientes com até 8 anos de estudo (RP=2,0 [IC95% 1,1–3,8]), que não viviam com um companheiro (RP=2,3 [IC95% 1,2–4,3]), que realizaram o pré-natal no setor público (RP=1,9 [IC95% 1,0–3,7]) e que tiveram um parto via cesárea (RP=6,0 [IC95% 2,9–12,4]) apresentaram maior probabilidade de ausência de acompanhante de parto. Conclusão: Os resultados apontam evidências relevantes para o seguimento da verificação da presença do acompanhante de parto no sul do Brasil, indicando a necessidade de melhor aproveitamento e adesão desta prática. Além disso, a lei que aprova a presença do acompanhante de parto no Brasil parece não estar sendo colocada em prática de modo integral, desrespeitando um direito das parturientes e impactando nos benefícios para a saúde materno-infantil.

ABSTRACT OBJECTIVE To assess risk factors associated with motor development delay at three months of age. METHODS Cross-sectional study with mothers and their three-month-old babies in Southern Brazil. The Bayley-III Scale of Infant and Toddler Development (BSID-III) and the Alberta Infant Motor Scale (AIMS) were used to assess motor development. RESULTS We evaluated 756 mothers and their three-month-old babies. The overall mean motor development assessed by the BSID-III and the AIMS was 104.7 (SD 13.5) and 55.4 (SD 25.4), respectively. When assessed by the BSID-III, the lowest motor development scores were among babies born by cesarean delivery (p = 0.002), prematurely (p < 0.001), and with low birth weight (p < 0.001). When assessed by the AIMS, babies born prematurely (p = 0.002) and with low birth weight (p=0.004) had the lowest motor development means. After a cluster analysis, we found that babies born by cesarean delivery, with low birth weight, and prematurely had more impaired motor development compared with children born without any risk factors. CONCLUSION Identifying risk factors allows the implementation of early interventions to prevent motor development delay and, therefore, reduce the probability of other future problems.

Este artigo avaliou a associação das condições de nascimento com o transtorno do déficit de atenção com hiperatividade (TDAH) em adultos utilizando dados de duas coorte de nascimento da cidade de Pelotas, Rio Grande do Sul, Brasil. Em 1982 e 1993, todos os nascimentos ocorridos na cidade foram identificados e prospectivamente acompanhados. Nos acompanhamentos aos 30 e 22 anos das coortes 1982 (n = 3.574) e 1993 (n = 3.780), respectivamente, os participantes foram examinados e psicólogos treinados aplicaram a Mini-International Neuropsychiatric Interview (M.I.N.I.). Aqueles indivíduos que preencheram os critérios diagnósticos do Manual Diagnóstico e Estatístico de Transtornos Mentais (DSM-5) foram definidos como positivos para TDAH. A regressão de Poisson com ajuste robusto da variância foi usada para estimar a razão de prevalência (RP) ajustadas para sexo, cor da pele materna, renda familiar, idade materna, escolaridade materna durante a gestação, estado civil materno, paridade e tabagismo materno durante a gestação. A prevalência do TDAH adulto foi de 4,4% e 4,5% nas coortes de 1982 e 1993, respectivamente. A prevalência de TDAH foi maior naqueles que nasceram com menor peso, mas não foi observada tendencia linear. Além disso, aqueles que nasceram com peso entre 3.000 e 3.499 gramas (g) (RP = 1,40, IC95%: 1,05-1,86) apresentaram maior risco para o transtorno. Para a idade gestacional, observamos uma relação inversamente proporcional acerca da presença de TDAH, os pré-termos apresentaram risco 33% maior (IC95%: 0,90-1,96) de ser considerado com TDAH do que os nascidos com 39 ou mais semanas, mas como o intervalo de confiança incluiu a nulidade, essa associação pode ter ocorrido ao acaso. Tais resultados indicam que o peso ao nascer e a idade gestacional podem estar associados ao TDAH adulto.

Studies relate Maternal-Fetal Attachment (MFA) to delays in child development, however, the relationship with the social-emotional development is still unclear. Thus, the aim of this study was to investigate the association between MFA and social-emotional development in infants at 3 months old, in a population-based sample in southern Brazil. This was a follow-up study corresponding to second and third wave of a population-based cohort study with pregnant women who were living in Pelotas (Southern Brazil). Social-emotional development was assessed using the Bayley Scales of Infant Development - Third Edition (BSID-III) and MFA was measured with the Maternal-Fetal Attachment Scale (MFAS). The sample consisted of 702 mother-infant dyads. In the adjusted analysis, MFA was a predictor of social-emotional development, even when controlled for sociodemographic, maternal mental health and infant characteristics. Thus, with each increase to one point in the MFA score, there was an increase of β = 0.14, 95% CI [0.05, 0.23] in the social-emotional development score. These findings highlight the importance of MFA in early child development. Thus, infants with positive experiences of affection since the gestational period will be able to develop positive social and emotional health.

Abstract Objectives: this study aimed to explore a set of factors associated with lower maternal-fetal attachment (MFA) in pregnant women. Methods: this is a cross-sectional study corresponding to the second wave of a cohort study with a population-based sample of pregnant women in the South of Brazil. The maternal-fetal attachment scale (MFAS) was used to measure MFA. Bivariate analysis was performed using the t-test and ANOVA. The variables that presented p

Abstract Evidence in the literature has suggested that there may be an association between thyroid antibodies and depression during pregnancy and in the postpartum period. Thus, this study aims to conduct a systematic review on the prevalence of postpartum depression (PPD) in women with thyroid abnormalities during pregnancy or in the postpartum period. For this review, we used four databases (PubMed, Lilacs, Scielo, and Scopus). Fifteen studies were selected; one study used a case–control design, four used a cross-sectional design and ten utilized prospective cohort designs. All studies were restricted to up to 1 year postpartum, and 46.7% focused on a period between immediate postpartum and 6 months postpartum. Estimates of the prevalence of PPD in pregnant women with thyroid disorders ranged between 8.3% and 36.0%. For follow-up studies, the cumulative incidence of self-reported depression from the primary episode in the first postpartum year was 6.3% in a high-city survey. Although some authors consider the status of positive anti-TPO antibodies to be a possible marker of vulnerability to depression , it is not yet possible to conclude whether thyroid function in the pregnancy-puerperal cycle is involved with the development of PPD.

BackgroundSuicide risk is prominent among the problems affecting populations, mainly due to the broad family, psychosocial and economic impact. Most individuals at suicidal risk have some mental disorder. There is considerable evidence that psychiatric disorders are accompanied by the activation of neuro-immune and neuro-oxidative pathways. The aim of the study is to evaluate the serum levels of oxidative stress biomarkers in women at risk of suicide after 18 months of postpartum.MethodsThis is a case-control study, nested within a cohort study. From this cohort, 45 women [15 without mood disorders and 30 with mood disorders (Major depression and Bipolar disorder)] were selected at 18 months postpartum, the depression and suicide risk were assessed using the Mini-International Neuropsychiatric Interview Plus (MINI-Plus) instrument, module A and C, respectively. Blood was collected and stored for later analysis of the reactive species (DCFH), superoxide dismutase (SOD), and glutathione reduced (GSH). For data analysis, the SPSS program was used. To compare the nominal covariates with the outcome GSH levels, the Student’s t-test or analysis of variance (ANOVA) was used. Spearman’s correlation was performed for analysis between the quantitative covariates and the outcome. To analyze the interaction between the factors, multiple linear regression was performed. Bonferroni analysis was used as an additional/secondary result to visualize differences in glutathione levels according to risk severity. After the adjusted analysis, p-values < 0.05 were considered statistically significant.ResultsThe percentage of suicide risk observed in our sample of women at 18 months postpartum was 24.4% (n = 11). After adjusting for the independent variables, only the presence of suicide risk remained associated with the outcome (β = 0.173; p = 0.007), low levels of GSH at 18 months after postpartum. Likewise, we verified the difference in GSH levels according to the degree of suicide risk, observing a significant association between the differences in glutathione means in the group of women with moderate to high risk compared to the reference group (no suicide risk) (p = 0.009).ConclusionOur findings suggest that GSH may be a potential biomarker or etiologic factor in women at moderate to high risk of suicide.

To evaluate the relationship between maternal cognitive performance and language and cognitive development of children between 24 and 36 months old of mothers who became pregnant in adolescence, in the city of Pelotas, Southern Brazil. This is a cross-sectional study nested in a cohort study with adolescent mothers who received prenatal care in the city’s public health system. To assess maternal cognitive performance, the Montreal Cognitive Assessment (MoCA) was used and Bayley Scales of Infant Development III (BSID-III) are used to assess children's language and cognition development. Data were analyzed using SPSS (Version 22.0) software. Pearson correlation, t-test, ANOVA and linear regression were performed. We evaluated 496 mother-child dyads. In the adjusted analysis, we found that children's language remained associated with maternal cognitive performance (p = .027, CI [0.0, 0.6]) and child’s gender (p < .001, CI [−7.2, −2.4]). Besides that children cognitive development remained associated with maternal cognitive performance (p = .008, CI [0.1, 0.6]) and child’s gender (p = .030, CI [−4.5, −0.2]). Our results suggest that poor maternal cognitive performance is associated with lower levels of children's language and cognitive development. The results contributing to early identification and intervention in children of mothers with poor cognitive performance at higher risk of negative developmental outcomes.

Robbery is one of the most common urban crimes, but little is known about its relationship with mental disorders in young adults. This study aimed to assess the relationship between robbery victimization and Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD) and comorbidity between MDD and GAD at 30 years of age. A birth cohort study has followed all children born in the city of Pelotas, southern Brazil, since 1982. At ages 23 and 30 years, participants were interviewed and asked about lifetime and recent experiences of robbery. Covariates were measured in interviews between birth and age 30 years. MDD and GAD were measured using the MINI-International Neuropsychiatric Interview. Adjusted prevalence ratio (aPR) and corresponding 95% confidence interval (CI) for associations between robbery and mental disorders were calculated using Poisson regression with robust standard error. Of 3,701 cohort members interviewed at age 30 years, 42% reported robbery victimization during their lifetime. Victimization across three periods (lifetime, past 10 years, past 12 months) was associated with increased occurrence of MDD, GAD, as well as the MDD and GAD comorbidity. The strongest associations were found to robbery occurring in the previous 12 months with the MDD and GAD comorbidity, both for burglary at home (aPR 2.52; 95% CI 1.52–4.22) or community family victimization (aPR 2.10; 95% CI 1.34–3.27). These findings highlight the importance of community violence for mental health in young adulthood, and the need for public policies to prevent violence as well as support services for victims to mitigate its adverse health consequences.

The COVID-19 pandemic has changed individuals and families, causing adverse psychological effects, especially in young adults, women, and parents. This study aimed to verify the prevalence of current major depressive episode (CMDE) in mothers of preschoolers (up to five years old) and its associated stressors during the COVID-19 pandemic in a municipality in the Southern Brazil. This is a cross-sectional, population-based study with mothers. All mothers were interviewed by telephone call during the COVID-19 pandemic. We used the Mini-International Neuropsychiatric Interview (M.I.N.I. Plus) to assess the presence of CMDE. Statistical analysis was conducted using the chi-square test and a multivariate logistic regression. We evaluated 666 mothers. The prevalence of CMDE was 12.3%. Mothers with financial losses had 2.1 (95%CI: 1.3-3.4) more odds of presenting CMDE than those financially stable. We observed that financial losses were determinant for the higher prevalence of depression in mothers.

Adults with childhood maltreatment history can face a difficult experience in transitioning to parenthood. Women with a history of emotional neglect in childhood tend to experience problematic attachment. The study's aim was to evaluate the relationship between childhood trauma and maternal-fetal attachment in pregnant women in a population-based study in Southern Brazil. This is a longitudinal study with pregnant women who were interviewed in two moments: before 24-weeks of pregnancy and 60 days after the first interview. We used the Childhood Trauma Questionnaire and the Maternal-Fetal Attachment Scale. The mean of maternal-fetal attachment in the general sample was 99.8 (± 10.8). The mean of emotional neglect was 8.9 (± 4.7); physical neglect 6.7 (± 2.8); sexual abuse 5.9 (± 3.0); physical abuse 6.8 (± 3.1) and emotional abuse 8.0 (± 4.1). After adjusted analysis, we found that pregnant women who suffered emotional neglect had 0.4 points less on the average on the maternal-fetal attachment, β = -0.4, CI 95% [-0.6, -0.2], and pregnant women who suffered emotional abuse had 0.2 points less on the average on the maternal-fetal attachment, β = -0.2, CI 95% [-0.5, -0.0]. Only emotional neglect and emotional abuse were associated with maternal-fetal attachment. This study showed that a history of childhood trauma can have a negative impact during the prenatal period, and can impair maternal-fetal attachment. The data found can assist health professionals in identifying factors that can protect and contribute to pregnant women who were victims of childhood trauma to face the transition to parenthood in the best possible way.

Given the importance that love has in individuals’ lives, and considering that more specific studies about the relationship between depression and the way people love are lacking, the aim of the current study was to evaluate the effect of major depressive disorder (MDD) on “love styles.” This study was nested in a cohort of adolescent mothers. Women were assessed for MDD at each point of assessment: during pregnancy (T1), at between 30 and 60 postpartum days (T2), and at approximately 30 postpartum months (T3), by using the Mini International Neuropsychiatric Interview (MINI PLUS) tool. The Love Attitudes Scale (LAS) was administered to assess the six love styles at T3. Logistic regression analyses were carried out to express the strength of depression on love styles. We found that chronic major depression had the largest effect on the love styles (low Eros, high Mania, and high Agape), followed by current major depression. However, the same association was not observed in the perinatal period. Thus, the assessment of love style is relevant as it seems that an MDD-related injury in maternal life is related to their attitudes about love and there could be possible harmful consequences of these attitudes to the mother and the whole family.

Background: Studies on mental disorders prevalence and comorbidity, including suicidality, are scarce in low and middle-income settings. We aimed to describe the pattern of comorbidity between mental disorders and their association with suicidality. Methods: In 1982, all hospital deliveries in Pelotas (Southern Brazil) were identified (n = 5914) and have been prospectively followed. Participants were evaluated for the presence of common mental disorders (CMD) at the ages of 18–19, 23 and 30 years. In 2012–13 (30 years of age), trained psychologists evaluated 3657 individuals for disorders using the Mini International Neuropsychiatric Interview. Results: Prevalence of suicidal wishing, suicidal planning and lifetime suicidal attempt was 4.9%, 3.8% and 6.6%, respectively. Suicidal wishing was most strongly associated with having joint major depressive episode (MD) and lifetime suicidal attempt (OR = 26.4, 95%CI:13.9–50.4) with comorbid MD with mania/hypomania (OR = 21.2, 95%CI:6.93–65.1). Suicidal planning was most strongly associated with having joint MD and lifetime suicidal attempt (OR = 44.7, 95%CI:22.6–88.4), with comorbid MD and social anxiety disorder (OR = 30.6, 95%CI:13.0–72.0), and joint social anxiety disorder with lifetime suicidal attempt (OR = 26.3, 95%CI:8.33–82.7). Independently of other disorders, prospective and cross-sectional measures of CMD were associated with higher rates of suicidality. Limitations: We do not have data on suicide deaths in follow-up and the diagnostic instrument used at 30 years of age was not used in all previous follow-up. Conclusion: MD and social anxiety have independent and combined associations with suicidality, and also with they occur with lifetime suicidal attempt and other mental disorders.

Background/objective: There is an increasing number of older patients with human immunodeficiency virus infection due to the success of antiretroviral therapy, the improved prognosis and life expectancy of patients, and the higher number of new infections among older individuals. The main objective of the present study was to compare the characteristics of older human immunodeficiency virus patients with those of younger patients. Materials and methods: We conducted a cross-sectional study with human immunodeficiency virus-infected patients who were treated at the Specialized Care Service (Serviço de Assistência Especializada) for human immunodeficiency virus/AIDS in the city of Pelotas, South Brazil. Sociodemographic information as well as data on human immunodeficiency virus infection and treatment were collected. All participants underwent psychiatric and neurocognitive assessments, and their adherence to antiretroviral therapy was evaluated. Results: A total of 392 patients participated in the study, with 114 patients aged 50 years and older. The characteristics showing significant differences between older and younger human immunodeficiency virus-infected patients included race/ethnicity, comorbidities, duration and adherence to antiretroviral therapy, currently undetectable viral load, and cognitive impairment. Compared to younger patients, older patients were at higher risk of exhibiting cognitive impairment [OR 2.28 (95% CI: 1.35–3.82, p = 0.002)] and of having increased adherence to antiretroviral therapy [OR 3.11 (95% CI: 1.67–5.79, p

Objectives To verify the prevalence of current posttraumatic stress disorder (PTSD) in young adults, the occurrence of comorbidities and its association with quality of life. Methods This is a cross-sectional population-based study. The targeted population consisted on individuals aged 18 to 24 years old, who lived in the urban area of Pelotas-RS, Brazil. Cluster sampling was applied. PTSD and its comorbidities were assessed using the Mini International Neuropsychiatric Interview (MINI 5.0), whereas quality of life was evaluated with the eight domains of the Medical Outcomes Survey Short-form General Health Survey (SF-36). Results A total of 1,762 young adults were selected. The prevalence of PTSD was 2.1% and current episode of depression was the most prevalent comorbidity (71.9%). The individuals with PTSD had lower scores in all domains of quality of life. Conclusion These findings indicate that PTSD is associated with other psychopathologies, especially depression, and it has a substantial impact over quality of life in a sample of young adults.

Abstract Exposure to maternal symptoms of depression/anxiety has long-term negative consequences for child development, regardless of the contextual risk. The objective of this study was to investigate the relationship of the symptomatology of persistent maternal depression and anxiety with child dental fear. This study was nested in a cohort of adolescent mothers in southern Brazil. Symptomatology of maternal depression and anxiety was assessed during pregnancy and postpartum, when the mothers’ children were 24-36 months old, using Beck Depression Inventory and Beck Anxiety Inventory. The mothers answered a questionnaire to assess dental fear in their children, and to obtain socioeconomic and demographic data. Both mothers and their children were submitted to clinical oral examination (n= 540 dyads) to obtain oral health data. Multivariate hierarchical Poisson regression analysis was used to determine associations (p < 0.05). At data collection, the prevalence of maternal depressive symptoms was 39.1%, and anxiety was observed in 27.8% of the mothers, whereas 21.6% of the children presented dental fear. In the adjusted analysis, children’s dental fear was positively associated with mothers’ presenting depressive symptomatology and caries experience. The depression symptomatology trajectory was not associated with dental fear, whereas mothers with persistent symptoms of anxiety reported higher prevalence of dental fear toward their offspring. The findings of symptomatology of maternal depression observed at data collection and persistence of anxiety may negatively impact the child’s perception of dental fear. Mothers are the main caregivers and primary models responsible for transmitting health-related behaviors; consequently, mental disorders affecting mothers may negatively impact their children.

Objective: To assess the prevalence of anxiety disorders and associated factors in young adults. Methods: Cross-sectional population-based study of individuals between the ages of 18 and 24 years randomly selected from 89 census-based sectors to ensure an adequate sample size. Household selection within the sectors was performed according to a systematic sampling process. Anxiety disorders were assessed using the Mini International Neuropsychiatric Interview (MINI). The final sample comprised 1,560 young adults. Results: Of the participants who were diagnosed with anxiety disorders, 12.3% had agoraphobia, 9.7% had generalised anxiety disorder, 4.0% had social phobia, 3.3% had obsessive-compulsive disorder, 2.5% had panic disorder, and 2.1% had post-traumatic stress disorder; only 23.8% had received any previous treatment. Anxiety disorders were associated with sex, socioeconomic status, psychiatric problems in parents, alcohol abuse, and tobacco use. Conclusions: The identification of factors associated with anxiety disorders in young people enables us to develop intervention strategies. Anxiety disorders are not only highly prevalent but are also associated with significant functional impairment, significant reductions in quality of life, lower productivity, and higher rates of comorbidities.

OBJECTIVES: To describe the prevalence of Major Depressive Disorder (MDD) during pregnancy in teenage mothers and to assess its association with socio-demographic characteristics, obstetric history and psychosocial variables. METHODS: A cross-sectional study was conducted with a sample of pregnant teenagers enrolled in the national public health system in the urban area of Pelotas, southern Brazil. MDD was assessed with the Mini International Neuropsychiatric Interview, the Abuse Assessment Screen was used to identify physical abuse within the last 12 months and during pregnancy, and social support was assessed with the Medical Outcomes Survey Social Support Scale. RESULTS: Forty-three (4.94%) potential subjects refused to participate, resulting in 828 total participants. The prevalence of MDD was 17.8%, 9.2% reported they had been subjected to violence within the last 12 months, while 5.8% had suffered violence during pregnancy, and the mean (SD) overall social support score was 87.40 (11.75). After adjustment, we found the highest incidence of MDD in adolescents with less than 8 years of education, followed by those with previous episodes of MDD and those with lower overall social support. CONCLUSIONS: MDD is a relatively common condition in pregnant teenagers and appears to be more prevalent in young mothers who are both socioeconomically and psychosocially underprivileged.

O baixo peso ao nascer está relacionado com morbimortalidade e sequelas no desenvolvimento infantil, impactando nos custos dos sistemas de saúde, por isso é importante avaliar fatores que o influenciam, estimando seu impacto no Sistema Único de Saúde (SUS). Este é um estudo prospectivo aninhado a uma coorte de gestantes que realizaram pré-natal e parto exclusivamente pelo SUS nos hospitais com UTI da cidade de Pelotas, Rio Grande do Sul, Brasil. Entre os resultados, concluiu-se que mães com episódios de depressão gestacional apresentam quase quatro vezes mais chances de ter um filho com baixo peso ao nascer (RP = 3,94; IC: 1,49-10,36). Valendo-se do cálculo da fração atribuível na população, estima-se que, na população geral, 36,17% dos bebês com baixo peso ao nascer são filhos de mães que tiveram episódio depressivo, estimando-se um custo que pode chegar a mais de R$ 76 milhões no Brasil. Sugere-se que se ampliem as ações preventivas e curativas para as gestantes na área da saúde mental, possibilitando melhor desfecho de saúde dos recém-nascidos, e que se utilizem adequadamente os recursos do SUS.Low birth weight is related to morbidity and mortality and sequelae during infant development, thereby impacting health system costs. It is thus important to evaluate factors that influence low birth weight and to estimate their impact on the Brazilian Unified National Health System (SUS). This was a nested prospective study in a cohort of pregnant women who received prenatal care and gave birth in the National Health System in hospitals with ICUs in the city of Pelotas, Rio Grande do Sul State, Brazil. Gestational depression was associated with a fourfold risk of low birth weight (PR = 3.94; CI: 1.49-10.36). Based on the population-attributable fraction, in the overall population an estimated 36.17% of low birth weight infants are born to mothers with an episode of depression during pregnancy, with an estimated cost of more than R$76 million (U$38 million) in Brazil. The study recommends the expansion of preventive and therapeutic mental health care measures for pregnant women and the adequate use of resources in the Unified National Health System to improve neonatal outcomes.

Objectives: To estimate the prevalence of daily smoking among users of three primary health care units affiliated with a university hospital in the municipality of Pelotas, southern Brazil, and to identify factors associated with daily tobacco consumption. Methods: This cross-sectional study included all individuals over 14 years of age who sought treatment at the health care units between June 29, 2009, and February 23, 2010, and lived in the area covered by the unit. Interviews were conducted during home visits to collect data on sociodemographic characteristics and health behaviors; the Mini International Neuropsychiatric Interview (MINI) was used to assess the presence of mood disorders; and a question from the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) on the daily use of tobacco in the past 3 months was used to assess smoking. Results: The total sample comprised 1,848 individuals, mostly female (72.9%), aged between 46 and 60 years (28.5%), and belonging to socioeconomic class C (61%). The prevalence of daily smoking was 23.4% (n = 432), and there was a statistically significant difference between men and women: 27 vs. 22.1% (p < 0.050). Conclusion: Our findings confirm a high prevalence of smoking among users of primary health care units, underscoring the need for a more accurate process of diagnosis and treatment at these facilities.Objetivos: Estimar a prevalência do uso diário de tabaco entre usuários de três unidades básicas de saúde (UBSs) vinculadas a um hospital universitário na cidade de Pelotas (RS) e identificar fatores associados ao consumo diário de tabaco. Métodos: Participaram deste estudo transversal todos os indivíduos maiores de 14 anos que procuraram atendimento nas UBSs no período de 29 de junho de 2009 a 23 de fevereiro de 2010 e que moravam na área de abrangência da UBS. Entrevistas foram realizadas durante visitas domiciliares para coletar dados sobre características sociodemográficas e comportamentos de saúde; a entrevista estruturada Mini International Neuropsychiatric Interview (MINI) foi utilizada para avaliar a presença de transtornos de humor; e uma pergunta do instrumento Alcohol, Smoking and Substance Involvement Screening Test (ASSIST) sobre o uso diário de tabaco nos últimos 3 meses foi utilizada para avaliar o tabagismo. Resultados: A amostra total incluiu 1.848 indivíduos, sendo a maioria do sexo feminino (72,9%), com idade entre 46 e 60 anos (28,5%) e pertencentes à classe socioeconômica C (61%). A prevalência de uso diário de tabaco foi de 23,4% (n = 432), com diferença estatisticamente significativa entre homens e mulheres: 27 versus 22.1% (p < 0,050). Conclusão: Nossos achados confirmam uma alta prevalência de tabagismo entre os usuários de UBSs, reforçando a necessidade de um processo de diagnóstico e tratamento mais eficiente nessas instituições.

Esta investigação visou identificar os fatores associados ao bem-estar psicológico em jovens de 18 a 24 anos de Pelotas, Rio Grande do Sul, Brasil. Em estudo transversal de base populacional, 1.621 jovens responderam a um questionário estruturado com questões referentes a dados sociodemográficos, prática de religião, trabalho remunerado, uso de substâncias e o Mini International Neuropsychiatric Interview (MINI) para avaliação dos transtornos psiquiátricos. A Escala de Faces de Andrews avaliou o bem-estar psicológico. A regressão de Poisson foi utilizada para análise multivariada. Dos entrevistados, 85,3% apresentaram bem-estar psicológico, que esteve associado ao não uso de drogas ilícitas, ao trabalho remunerado, à prática de religião, às classes socioeconômicas A e B, à alta escolaridade e a não presença de transtornos psiquiátricos. Programas que visem à redução da pobreza, incentivo à educação, identificação e prevenção de uso de drogas em jovens são de extrema importância para a melhoria do bem-estar psicológico e prevenção da saúde.This study aimed to identify factors associated with psychological well-being among young people 18 to 24 years of age in Pelotas, Rio Grande do Sul State, Brazil. In a population-based cross-sectional study, 1,621 subjects answered a structured questionnaire on socio-demographic data, religion, employment, and substance use, as well as the Mini International Neuropsychiatric Interview (MINI) to assess psychiatric disorders. The Faces Scale (Andrews) was used to evaluate psychological well-being. Poisson regression was used for multivariate analysis. Of the total sample, 85.3% displayed psychological well-being, which was positively associated with non-use of illicit drugs, current employment, religion, socioeconomic status (classes A and B), higher educational levels, and absence of psychiatric disorders. Programs to reduce poverty and encourage education and identification and prevention of drug use among youths are of paramount importance to improve their health and psychological well-being.

Este estudo teve por objetivo verificar a relação entre a presença de transtornos de ansiedade e risco de suicídio em jovens. Em delineamento transversal de base populacional, os jovens respondiam a um questionário sobre questões sociodemográficas, comportamentais e de saúde. Avaliou-se o bem-estar psicológico através da Escala de Faces de Andrews e consumo de substâncias foi efetuado pelo Teste de Triagem do Envolvimento com Álcool, Cigarro e Outras Substâncias, (Alcohol, Smoking and Substance Involviment Screening Test - ASSIST). A Mini Internacional Neuropsychiatric Interview 5.0 avaliou transtornos de ansiedade e o risco de suicídio. Dos 1.621 jovens entrevistados, 20,9% apresentaram algum transtorno de ansiedade e 8,6% risco de suicídio. A presença de algum transtorno de ansiedade esteve significativamente associada ao risco de suicídio (RP 6,10 IC95% 3,95 a 9,43). Dessa forma, salienta-se a importância de maior atenção ao risco de suicídio também em pacientes com transtornos de ansiedade.Este estudio tubo por objetivo verificar la relación entre la presencia de trastornos de ansiedad y riesgo de suicidio en jóvenes. En delineamiento transversal de base poblacional, los jóvenes respondían a un cuestionario sobre cuestiones sociodemográficas, comportamentales y de salud. Se evaluó el bienestar psicológico por medio de la escala de fases de Andrews y consumo de sustancias efectuada por la prueba de detección del envolvimiento con alcohol, cigarrillo y otras sustancias, (Alcohol, Smoking and Substance Involviment Screening Test - ASSIST). La Mini Internacional Neuropsychiatric Interview 5.0 evaluó trastornos de ansiedad y el riesgo de suicidio. De los 1.621 jóvenes entrevistados, 20,9% presentaron algún trastorno de ansiedad y 8,6% riesgo de suicidio. La presencia de algún trastorno de ansiedad estuvo significativamente asociada al riesgo de suicidio (RP 6,10 IC95% 3,95 a 9,43). De esa forma, se resalta la importancia de mayor atención al riesgo de suicidio también en pacientes con trastornos de ansiedad.This study aimed at investigating the relationship between the presence of anxiety disorders and suicide risk in young adults. In a cross-sectional population-based design young adults answered a questionnaire about sociodemographic, behavioral and health characteristics. The measure of psychological well-being was made by Faces Scale of Andrews while the substances use evaluation was performed according to the Alcohol, Smoking and Substance Involvement Screening Test (ASSIST). The Mini International Neuropsychiatric Interview 5.0 evaluated anxiety disorders and suicide risk. Among the 1.621 young adults interviewed, 20.9% had some anxiety disorders and 8.6% suicide risk. After multivariate analysis, the presence of any anxiety disorder was significantly associated with suicide risk (PR 6.10 95% CI 3.95 to 9.43). Thus, it is highlighted the importance of greater attention to suicide risk in those patients with anxiety disorders.

O objetivo foi avaliar risco de suicídio e comportamentos de risco em jovens. Estudo transversal na zona urbana de Pelotas, Rio Grande do Sul, Brasil, realizado por amostragem sistemática.

A primeira relação sexual é considerada um evento importante na vida dos jovens e tem iniciado cada vez mais cedo. O objetivo do presente estudo foi descrever os fatores relacionados à idade precoce da primeira relação sexual, de jovens de 18 a 24 anos na cidade de Pelotas, Rio Grande do Sul, Brasil. Este é um estudo transversal de base populacional, em uma amostra representativa de 1.621 jovens que ocorreu entre agosto de 2007 e dezembro de 2008. Foram aplicados questionários sobre comportamentos de saúde que continham itens relativos à sexualidade. A regressão de Cox foi utilizada para aferir a associação com a idade precoce de início da vida sexual. Após a análise multivariada, as variáveis diretamente relacionadas com a iniciação sexual precoce foram: sexo masculino, baixo nível socioeconômico, baixa escolaridade, ter pais separados, morar com companheiro(a), não praticar uma religião, uso de tabaco e drogas, e o não uso da camisinha na última relação. Considerando o contexto social atual, evidencia-se a necessidade de uma adequada orientação sexual com aspecto preventivo.First sexual intercourse is considered an important event in young people's lives and has occurred at an increasingly early age. The aim of this study was to identify factors associated with early age at first intercourse in individuals 18 to 24 years of age in Pelotas, Rio Grande do Sul State, Brazil. This was a population-based cross-sectional study in a representative sample of 1,621 young people from August 2007 to December 2008. Subjects answered a questionnaire on health behaviors, including items related to their sexual lives. Cox regression was used to assess the association between early age at sexual initiation. After multivariate analysis, variables that are directly related to early sexual initiation were: male gender, low socioeconomic status, low schooling, divorced parents, living with a partner, not practicing a religion, smoking, drug use in the previous three months, and non-use of condoms during last intercourse. Considering the current social context, the study highlights the need for adequate sexual orientation with a preventive approach.

OBJECTIVE: We describe the prevalence of depressive and bipolar spectrum episodes in fathers in antenatal and postnatal periods, as well as at 12 months after childbirth. METHOD: A longitudinal follow-up study was conducted with a representative sample of 739 fathers whose children were born between April 2007 and May 2008 in maternity wards in the city of Pelotas, southern Brazil. Paternal psychopathology was measured with the Mini Neuropsychiatric Interview (MINI) across three time points: between 28 and 34 weeks of pregnancy (T1), 30 to 60 days postpartum (T2), and 12 months after childbirth (T3). RESULTS: The prevalence of depressive episodes was 5.0% at T1, 4.5% at T2, and 4.3% at T3. Mixed episodes were present in 3%, 1.7%, and 0.9% of subjects, respectively, and accounted for 61.1% of the cases of depression in the antenatal period, 37.5% in postpartum, and 21.4% at 12 months. Depressive and manic/hypomanic episodes were significantly associated during pregnancy and in postpartum, but not at 12 months after childbirth. CONCLUSION: Bipolar episodes were common in men with depressive symptoms during their partner's pregnancy in the postpartum period and, to a lesser extent, 12 months after childbirth. Therefore, this population should be carefully investigated for manic and hypomanic symptoms.OBJETIVO: Verificar a prevalência dos episódios depressivos e bipolares em homens no período pré e pós-natal, assim como 12 meses após o parto. MÉTODO: Estudo longitudinal com amostra de pais cujas crianças nasceram entre abril de 2007 e maio de 2008 em maternidades da cidade de Pelotas-RS, no sul do Brasil. Episódios depressivos e maníacos/hipomaníacos foram mensurados com o Mini Neuropsychiatric Interview em três tempos diferentes: entre a 28ª e 34ª semanas de gestação (T1), 30 a 60 dias após o parto (T2) e 12 meses após o nascimento da criança. RESULTADOS: A prevalência de episódios depressivos foi 5,0% em T1, 4,5% em T2 e 4,3% em T3. Episódios mistos estiveram presentes em 3,0, 1,7 e 0,9%, respectivamente, e somaram 61,1% de casos de depressão antenatal, 37,5% pós-natal e 21,4% aos 12 meses pós-parto. Episódio depressivo e maníaco/hipomaníaco esteve significativamente associado durante a gestação e o pós-parto. CONCLUSÃO: Episódios bipolares são comuns em homens com sintomas depressivos durante a gestação de suas companheiras e no período pós-natal. Essa população deveria ser cuidadosamente investigada para sintomas maníacos e hipomaníacos, a fim de ser adequadamente tratada.

O objetivo foi verificar a prevalência de transtornos mentais comuns (TMC) e sua associação com qualidade de vida em jovens da cidade de Pelotas, Rio Grande do Sul, Brasil. Estudo transversal de base populacional com jovens de 18 a 24 anos. A seleção amostral foi realizada por conglomerados. Para a investigação dos transtornos mentais comuns foi aplicado o Self Report Questionnaire (SRQ-20), enquanto os níveis de qualidade de vida foram mensurados por intermédio da Medical Outcomes Survey Short-form General Health Survey (SF-36). A prevalência de TMC na amostra estudada foi de 24,5% (N = 382), apresentando-se mais evidente entre as mulheres, entre aqueles que pertenciam à menor classe socioeconômica (D ou E), não estavam estudando, não estavam trabalhando, consumiram álcool e usaram tabaco pelo menos uma vez na última semana e que fizeram uso de alguma substância ilícita nos últimos três meses. Os jovens com TMC obtiveram uma menor média nos escores da SF-36 em todos os domínios de qualidade de vida avaliados. Deve-se investir em medidas preventivas de TMC no intuito de proporcionar uma melhor qualidade de vida à população.

OBJETIVO: Analisar a associação entre comportamentos violentos de adolescentes e a coabitação parento-filial. MÉTODOS: Estudo transversal de base populacional realizado na área urbana de Pelotas, RS, em 2002, com amostragem em múltiplos estágios. Foram entrevistados 960 adolescentes com utilização de questionário auto-aplicado. As variáveis dependentes (uso de armas e envolvimento em brigas no último ano foram referidos pelos adolescentes) e a variável independente coabitação parento-filial foram submetidas a análise pelo teste de qui-quadrado e razão de prevalências, ajustada para idade, sexo, nível socioeconômico e relato de uso na vida e recente de álcool, tabaco ou drogas ilícitas. RESULTADOS: O envolvimento em brigas no último ano foi referido por 23% dos sujeitos e o uso de armas por 9,6%. A razão de prevalência de ocorrência desses comportamentos foi de 1,38 (IC95%: 0,71; 2,68, p = 0,34) para envolvimento em brigas e de 1,68 (IC95%: 1,06; 2,67, p = 0,03) para uso de armas, tendo como referência sujeitos que coabitavam com pai, com mãe ou com ambos. CONCLUSÕES: A coabitação parento-filial deve ser considerada em políticas de prevenção ao uso de armas por crianças e adolescentes, mas recomenda-se o cuidado de não estigmatizar crianças e adolescentes que não coabitam com pais e mães.OBJETIVO: Analizar la asociación entre comportamientos violentos de adolescentes y la co-habitabilidad parental-filial. MÉTODOS: Estudio transversal de base poblacional realizado en el área urbana de Pelotas, Sur de Brasil, en 2002, con muestreo en múltiples fases. Fueron entrevistados 960 adolescentes con utilización de cuestionario auto-aplicado. Las variables dependientes (uso de armas y envolvimiento en peleas en el último año fueron referidos por los adolescentes) y la variable independiente co-habitabilidad parental-filial fueron sometidas a análisis por la prueba e chi-cuadrado y la tasa de prevalencias, ajustada para edad, sexo, nivel socioeconómico relato de uso en la vida y reciente de alcohol, tabaco o drogas ilícitas. RESULTADOS: El envolvimiento en peleas en el último año fue referido por 23% de los sujetos y el uso de armas por 9,6%. La tasa de prevalencia de ocurrencia de estos comportamientos fue de 1,38 (IC 95%: 0,71;2,68, p=0,34) para envolvimiento en peleas y de 1,68 (IC 95%: 1,06;2,67, p=0,03) para uso de armas, teniendo como referencia sujetos que co-habitaban con padre, con madre o con ambos. CONCLUSIONES: La co-habitabilidad parental-filial debe ser considerada en políticas de prevención al uso de armas por niños y adolescentes, pero se recomienda el cuidado de no estigmatizar niños y adolescentes que no co-habitan con padres y madres.OBJECTIVE: To analyze the association between violent behavior in adolescents and parent-child cohabitation. METHODS: A population-based cross-sectional study with multiple-stage sampling was performed in the urban area of the city of Pelotas, Southern Brazil, in 2002. A total of 960 adolescents were interviewed using a self-applied questionnaire. The dependent variables (use of weapons and involvement in fights in the previous year were reported by adolescents) and the independent variable (parent-child cohabitation) were analyzed with the chi-square test and prevalence ratios, adjusted for age, sex, socioeconomic level and reporting of alcohol, tobacco or illicit drug use, both recently and throughout life. RESULTS: Involvement in fights in the previous year was reported by 23% of participants and use of weapons by 9.6%. Prevalence ratios of occurrence of such behaviors was 1.38 (95% CI: 0.71; 2.68, p=0.34) for involvement in fights and 1.68 (95% CI: 1.06; 2.67, p=0.03) for use of weapons, including "adolescents living with the father, mother or both" as reference. CONCLUSIONS: Parent-child cohabitation must be considered in policies aimed at preventing the use of weapons by children and adolescents, although it is recommended that care should be taken not to stigmatize children and adolescents who do not live with their fathers and mothers.

O objetivo do presente estudo foi verificar a prevalência de transtornos mentais comuns (TMC) e sua relação com auto-estima, bem como outros fatores associados à ocorrência de TMC em gestantes. Foi realizado um estudo transversal aninhado a uma coorte no qual participaram gestantes atendidas no serviço de saúde do Sistema Único de Saúde na cidade de Pelotas, Estado do Rio Grande do Sul, Brasil. Foi utilizado para o rastreamento de transtornos mentais comuns o Self-Reporting Questionnaire (SRQ-20) e, para avalia a auto-estima, a Escala de Auto-Estima de Rosenberg. A amostra constituiu-se de 1.267 gestantes, que tinham em média 25 anos (dp = 6,53). A média de auto-estima foi de 9,3 pontos (dp = 4,76) e a prevalência de TMC em gestantes foi de 41,4%. Evidenciou-se, também, que quanto menor a auto-estima da grávida maiores são as chances de associação a TMC (p < 0,001). Houve uma significativa associação entre maior prevalência de TMC e baixa auto-estima.The aim of this study was to assess the prevalence of common mental disorders and the association with self-esteem and other factors in pregnant women. A nested cross-sectional study was performed in a cohort of pregnant women treated in the public health system in Pelotas, Rio Grande do Sul State, Brazil. The Self-Reporting Questionnaire (SRQ-20) was used to screen for common mental disorders and the Rosenberg's Self-Esteem Scale for self-esteem. The sample consisted of 1,267 pregnant women with a mean age of 25 years (SD = 6.53). Mean self-esteem was 9.3 points (SD = 4.76), and prevalence of common mental disorders was 41.4%. Lower self-esteem was associated with higher odds of common mental disorders (p < 0.001). There was a significant association between higher prevalence of common mental disorders and low self-esteem.

OBJECTIVE: To estimate the prevalence of depression and correlate clinical and demographic characteristics in pregnant women assisted by the public health system in the city of Pelotas, RS, Brazil. METHOD: We performed a cross-sectional study focused on pregnant women assisted by the public health service. The Edinburgh Postnatal Depression Scale (EPDS) was used to screen for depression. RESULTS: In a sample of 1,264 pregnant women aged 12-46 years, 21.1% (n = 255) presented a depressive episode during pregnancy. The presence of depression was associated with older age, lower education, lack of a cohabiting partner, not being primiparous, planned pregnancy, abortion thoughts, psychological or psychiatric treatment, smoking and alcohol consumption during pregnancy, and stressful events. CONCLUSION: Pregnant women assisted by the Brazilian public health system presented a high prevalence of depression. Psychiatric history, lack of support, and stressful events increase the probability of antenatal depression.OBJETIVO: Estimar a prevalência de depressão, bem como fatores clínicos e características demográficas associados em grávidas assistidas por meio do sistema público de saúde da cidade de Pelotas, RS, Brasil. MÉTODO: Foi realizado um estudo transversal tendo como população-alvo as grávidas assistidas pelo sistema público de saúde. Para o rastreio da depressão foi utilizada a Edinburgh Postnatal Depression Scale. RESULTADOS: Em uma amostra de 1.264 mulheres grávidas com idade de 12 a 46 anos, 21,1% (n = 255) apresentaram episodio depressivo durante a gravidez. A presença de depressão foi associada com ter mais idade, menor grau educacional, não morar com companheiro, não ser primigesta, ter planejado a gestação, idealizar o aborto, ter feito tratamento psicológico ou psiquiátrico, consumir tabaco e/ou álcool durante a gravidez e ter sofrido algum evento estressor. CONCLUSÃO: As mulheres grávidas acompanhadas pelo sistema público de saúde apresentaram alta prevalência de depressão. História psiquiátrica, baixo suporte e eventos estressores aumentam a probabilidade de depressão no período pré-parto.

OBJECTIVE: To verify the prevalence and associated factors of suicidal ideation among adolescents aged 11 to 15 years. METHOD: Cross-sectional population-based study. Adolescents completed a self-report that contained the Children's Depression Inventory. Suicidal ideation was measured according to item 9 of the Children's Depression Inventory. Multivariate logistic regression analysis was applied using a hierarchical model. RESULTS: 1145 adolescents were invited to participate, and 1039 were interviewed (refusal rate: 9.26%). The prevalence of suicidal ideation was 14.1%. Factors associated to suicidal ideation: female gender, current alcohol consumption, use of illicit drugs, symptoms indicating conduct disorders and high Children's Depression Inventory scores for depressive symptoms. CONCLUSION: Prevention strategies should focus on female adolescents, especially those sexually active with probable mental health problems and substance use.OBJETIVO: Verificar a prevalência e fatores associados à ideação suicida entre adolescentes de 11 a 15 anos. MÉTODO: Estudo transversal de base-populacional. Os adolescentes responderam a um questionário auto-aplicável que continha o Children's Depression Inventory. A ideação suicida foi mensurada de acordo com o item 9 do Children's Depression Inventory. Foi utilizada a análise de regressão logística multivariada acompanhada de um modelo hierárquico. RESULTADOS: 1.145 adolescentes foram convidados a participar e 1.039 foram entrevistados (recusas: 9,26%). A prevalência de ideação suicida foi de 14,1%. Fatores associados à ideação suicida: sexo feminino, consumir álcool, uso de drogas ilícitas, apresentar sintomas indicativos de transtorno de conduta e elevada pontuação no Children's Depression Inventory para sintomas depressivos. CONCLUSÃO: Estratégias de prevenção devem priorizar adolescentes do sexo feminino, principalmente aquelas sexualmente ativas, com prováveis problemas de saúde mental e uso de substâncias.

OBJETIVO: Verificar se existe associação entre as alterações no sono dos bebês aos 12 meses de vida e a depressão pós-parto materna. MÉTODOS: Estudo do tipo transversal aninhado a uma coorte. A amostra foi constituída por mulheres que realizaram o acompanhamento pelo Sistema Único de Saúde (SUS), nas unidades básicas de saúde do município de Pelotas, e que tiveram seus partos a partir de junho/2006. Os bebês de 12 meses oriundos dessa gestação também fazem parte da amostra. Para avaliar a presença de sintomas depressivos nas mães, foi utilizada a Edinburgh Postnatal Depression Scale (EPDS) e foram investigados os seguintes comportamentos do sono dos bebês: horas de sono por dia, regularidade do horário para dormir e acordar, sono agitado e despertar noturno. Para análise, foi utilizada Regressão de Poisson. RESULTADOS: 35,7% dos bebês possuem alteração no padrão de sono. Após o ajuste ao modelo hierárquico proposto, a alteração no sono infantil manteve associação com a sintomatologia depressiva da mãe (p < 0,01). CONCLUSÕES: Os profissionais de saúde devem investigar rotineiramente os comportamentos de sono dos bebês e dar atenção à saúde mental das mães, a fim de identificar os problemas precocemente e oferecer suporte no manejo do sono dos bebês.OBJECTIVE: Verify whether there is association between sleep disorders in babies at 12 months of age and postpartum depression in motherhood. METHODS:Cross sectional study. The sample was made up of women who had done their prenatal medical care at the National Health System (SUS), at the health basic units in Pelotas and who had their deliveries from June, 2006. The 12 month old babies from these women are also part of the sample. In order to assess depressive symptoms in the mothers, Edinburgh Postnatal Depression Scale was used and the following sleeping behaviors of the babies were investigated: hours of sleep per day, regularity of sleep and wake up time, disturbed sleep and night awakening. Poisson Regression was used for the analysis. RESULTS: 35.7% of the babies showed alterations in their sleeping patterns. After adjusting for the proposed hierarchal model, sleep alteration of the babies was still associated with the depressive symptoms of the mothers (p < 0,01). CONCLUSIONS: Health professionals should regularly investigate sleeping behaviors of babies and pay attention to mothers' mental health in order to identify problems early and offer support in the management of babies' sleep.

OBJETIVO: Avaliar a prevalência de ideação suicida, assim como de seus fatores associados, em adolescentes entre 15 e 18 anos da cidade de Pelotas (RS). MÉTODOS: 960 adolescentes responderam a um questionário autoaplicado e sigiloso em estudo transversal de base populacional. A ideação suicida foi aferida por meio do item 17 do SRQ-20, que avalia transtornos psiquiátricos menores. Para a análise estatística, utilizou-se a regressão logística. RESULTADOS: A prevalência de ideação suicida foi de 7,7%. A baixa escolaridade da mãe, a baixa escolaridade do adolescente, o sedentarismo, o uso de álcool e de outras substâncias e o comportamento agressivo mantiveram associação estatisticamente significativa com ideação suicida. CONCLUSÃO: Programas preventivos devem preferencialmente atingir adolescentes de baixa escolaridade que apresentem comportamento agressivo e relatem uso de substâncias.

MÉTODOS: Estudo transversal de base populacional realizado entre 2005 e 2006, em Pelotas (RS), com 1.056 adolescentes entre 11 a 15 anos de idade. Foi aplicado um questionário de auto-preenchimento anônimo, baseado no modelo da Organização Mundial de Saúde para uso de drogas. Para análise dos dados, foi utilizada a regressão de Poisson. RESULTADOS: A prevalência de adolescentes que referiram o consumo de bebidas alcoólicas no último mês foi de 23,0% (IC 95%: 20,4;25,4), a prevalência foi de 21,7% entre o sexo feminino e 24,2% entre o masculino. A prevalência de consumo de álcool aos 11 anos foi de 11,9%. Na análise de regressão múltipla, entre adolescentes do sexo masculino, o uso de bebidas alcoólicas foi maior naqueles que relataram o uso de tabaco no último mês, nos mais velhos e naqueles que já tinham tido relação sexual. Nas adolescentes do sexo feminino a idade foi à única variável associada ao uso de bebidas alcoólicas. CONCLUSÕES: O uso de bebidas alcoólicas foi prevalente em ambos os sexos e com início extremamente precoce. Tabagismo e já ter tido relações sexuais também estiveram associados ao uso de bebidas alcoólicas. Há necessidade de medidas preventivas com maior precocidade, visando controlar o uso de álcool na faixa etária dos 11 aos 15 anos.OBJETIVO: Estimar la prevalencia y los factores asociados al uso de alcohol por adolescentes. MÉTODOS: Estudio transversal de base poblacional realizado entre 2005 y 2006, en Pelotas (Sur de Brasil), con 1.056 adolescentes entre 11 y 15 años de edad. Fue aplicado un cuestionario de auto-llenado anónimo, basado en el modelo de la Organización Mundial de la Salud para uso de drogas. Para análisis de los datos, fue utilizada la regresión de Poisson. RESULTADOS: La prevalencia de adolescentes que refirieron el consumo de bebidas alcohólicas en el último mes fue de 23,0% (IC 95%: 20,4; 25,4), la prevalencia fue de 21,7% entre el sexo femenino y 24,2% entre el masculino. La prevalencia de consumo de alcohol a los 11 años fue de 11,9%. En el análisis de regresión múltiple, entre adolescentes del sexo masculino, el uso de bebidas alcohólicas fue mayor en aquellos que relataron el uso de tabaco en el último mes, en los más viejos y en aquellos que ya habían tenido relación sexual. En las adolescentes del sexo femenino la edad fue la única variable asociada al uso de bebidas alcohólicas. CONCLUSIONES: El uso de bebidas alcohólicas fue prevalerte en ambos sexos y con inicio extremadamente precoz. Tabaquismo y el haber tenido relaciones sexuales también estuvieron asociados al uso de bebidas alcohólicas. Hay necesidad de medidas preventivas con mayor precocidad, visando controlar el uso de alcohol en el intervalo de edad de 11 a los 15 años.OBJECTIVE: To estimate the prevalence and factors associated with alcohol use among adolescents. METHODS: Population-based, cross-sectional study performed from 2005 to 2006, in the city of Pelotas, Southern Brazil, with 1,056 adolescents aged between 11 and 15 years. An anonymous, self-applied questionnaire was used, based on the World Health Organization model for drug use. Poisson regression was employed to analyze data. RESULTS: Prevalence of adolescents who reported alcoholic beverage consumption in the last month was 23.0% (95% CI: 20.4;25.4), prevalence was 21.7% among females and 24.2% among males. Prevalence of alcohol consumption at 11 years of age was 11.9%. In the multiple regression analysis, alcoholic beverage use by male adolescents was higher among those who reported tobacco use in the last month, those who were older, and those who had already had sexual intercourse. Among female adolescents, age was the only variable associated with alcoholic beverage use. CONCLUSIONS: Alcoholic beverage use was prevalent in both sexes and began at a very early age. Smoking and previous sexual intercourse were also associated with this use. Preventive measures need to begin earlier, aiming to control alcohol use in the 11-to-15-year age group.

A cross-sectional population-based study was conducted to identify the prevalence of common mental disorders and verify the association with chronic non-communicable diseases (NCDs) and the self-reported number of chronic diseases. The Self-Reporting Questionnaire (SRQ-20) was applied in a multi-stage random sample of 1,276 adults aged 40 and older. Socio-demographic, behavioral, and health-related variables were also obtained using a structured questionnaire. Prevalence of common mental disorders was 30.2%. Lower schooling and social class and the 46-55-year age bracket were associated with psychiatric morbidity. Each chronic illness was independently associated with common mental disorders. However, a stronger association was found between common mental disorders and the total number of self-reported chronic conditions, with a prevalence ratio of 4.67 (95%CI: 3.19-6.83) for five or more self-reported NCDs. The current study emphasizes the importance of common mental disorders in chronically ill patients, particularly in those with more total chronic conditions.Estudo transversal de base populacional foi conduzido tendo como objetivos avaliar a prevalência dos transtornos mentais comuns e verificar sua associação com determinadas enfermidades crônicas e com o número de doenças crônicas relatadas pelo indivíduo. Para a avaliação de transtornos mentais comuns, o Self-Reporting Questionnaire (SRQ-20) foi aplicado em 1.276 adultos com 40 anos ou mais. Variáveis sócio-demográficas, comportamentais e relacionadas à saúde foram obtidas por meio de um questionário estruturado. Os transtornos mentais comuns apresentaram uma prevalência de 30,2%, estando associados à baixa escolaridade e classe social, e à faixa etária de 46-65 anos. Todas as doenças crônicas pesquisadas mostraram-se associadas aos transtornos mentais comuns. Entretanto, o número de enfermidades apresentadas pelo indivíduo teve maior importância do que cada uma delas individualmente, com uma razão de prevalência de 4,67 e intervalo de 95% de confiança: 3,19-6,83 para cinco ou mais doenças relatadas. O presente estudo realça a importância de se atentar para os transtornos mentais em indivíduos com enfermidades crônicas, principalmente naqueles que se apresentam com um grande número de doenças.

O estudo tem como objetivo mensurar a auto-estima e fatores associados em gestantes atendidas pelo Sistema Único de Saúde (SUS) na cidade de Pelotas, Rio Grande do Sul, Brasil. É do tipo transversal, tendo-se entrevistado 560 gestantes nos meses de maio a novembro de 2006, nos ambulatórios e enfermarias dos hospitais universitários e do centro de atendimento da Prefeitura Municipal. Dentre as gestantes atendidas, 62,9% receberam o diagnóstico de alto-risco. Para avaliação da auto-estima foi utilizada a escala de Rosenberg. Na amostra total a média de pontos na escala foi de 9,2 e o desvio-padrão de 4,6. As variáveis associadas positiva e significativamente com auto-estima foram idade, nível de escolaridade e nível econômico. Já as variáveis percepção de risco à saúde do bebê e número de gestações mostraram-se associadas negativamente à auto-estima. Além disso, as gestantes com condição gestacional de alto-risco têm uma auto-estima mais elevada quando comparadas com as de baixo-risco.This study analyzes self-esteem and associated factors in pregnant women treated by the Unified National Health System (SUS) in the city of Pelotas, Rio Grande do Sul State, Brazil. Using a cross-sectional design, 560 pregnant women were interviewed from May to November 2006. The interviews were held in specific locations like University outpatient clinics and hospital wards and a center run by the city government. A full 62.9% were diagnosed as high-risk pregnancies. Mean self-esteem according to the Rosenberg scale was 9.2 (SD = 4.6). Variables showing a positive, significant association with self-esteem were age, schooling, and income. Perception of risk to the unborn infant's health and parity were both negatively associated with maternal self-esteem. These high-risk pregnant women also showed higher self-esteem than low-risk pregnant women.

Este trabalho procurou estimar a prevalência e os fatores associados ao transtorno da conduta em adolescentes com idade entre 11 e 15 anos. Realizou-se um estudo transversal com 1.145 adolescentes na cidade de Pelotas, Rio Grande do Sul, Brasil. Os adolescentes responderam a um questionário auto-aplicado. O transtorno da conduta foi avaliado através do Mini International Neuropsychiatric Interview (MINI). Foi investigada a associação desta psicopatologia com sexo, idade, nível sócio-econômico, escolaridade do adolescente, reprovação na escola, religião, sedentarismo, consumo de álcool, tabagismo, uso de drogas, depressão e sofrer bullying. A regressão ordinal foi usada para a análise estatística. Estima-se que, entre os entrevistados, 29,2% tenham transtorno da conduta. Na análise multivariada, a chance de um adolescente apresentar um ponto a mais na escala que avalia transtorno da conduta foi 2,04 (IC95%: 1,53-2,71) vezes maior no sexo masculino. O consumo de bebida alcoólica, o uso de drogas e sofrer bullying estiveram associados com maior pontuação na escala de transtornos de conduta. Os resultados também mostraram que os fatores associados ao transtorno da conduta apontam para a forte interrelação entre comportamentos de saúde na adolescência.This study proposed to estimate the prevalence of behavioral disorders and associated factors in adolescents (11-15 years), using a cross-sectional design (n = 1,145). Subjects answered a self-administered questionnaire. Behavioral disorder was assessed with the Mini International Neuropsychiatric Interview (MINI). The study analyzed disorders in relation to gender, age, socioeconomic status, schooling, failure in school, religion, smoking, sedentary lifestyle, alcohol consumption, drug use, depression, and bullying (as victim). Ordinal regression was used for the statistical analysis, with a hierarchical model for the outcome. An estimated 29.2% of the sample presented behavioral disorders. In the multivariate analysis, the odds ratio for a male adolescent to present one additional point on the behavioral disorder scale was 2.04 (95%CI: 1.53-2.71). Alcohol consumption, drug use, and suffering bullying were associated with higher scores on the behavioral disorder scale. The findings also showed that the factors associated with behavioral disorder showed a strong interrelationship between health behaviors in adolescence.

Este trabalho determina a prevalência e fatores associados ao uso de antidepressivos em adultos residentes na área urbana da cidade de Pelotas, Rio Grande do Sul, Brasil. Foi realizado um estudo transversal em uma amostra representativa de adultos com idade igual ou superior a 40 anos, moradores na zona urbana de Pelotas, em 2006. Para as comparações entre proporções, utilizou-se o teste de qui-quadrado e, para a análise multivariada, a regressão logística não condicional. Foram entrevistados 1.327 adultos, dos quais 9,3% tinham usado antidepressivos. O consumo desses medicamentos associou-se significativamente ao sexo feminino (OR: 2,45; IC95%: 1,50-4,02); ao nível sócio-econômico mais elevado, classes A e B (OR: 2,07; IC95%: 1,28-3,34); e a não estar exercendo uma atividade de trabalho (OR: 1,65; IC95%: 1,06-2,55). A prevalência de uso de antidepressivos foi superior às encontradas em outros estudos. Os determinantes individuais de utilização poderão servir de embasamento às estratégias para diminuir o consumo de antidepressivos nesses grupos.The objective of this study was to estimate the prevalence and determinants of antidepressant use among adults in a city in southern Brazil. The cross-sectional study was based on interviews with adults 40 years or older living in the urban area of Pelotas, Rio Grande do Sul State, Brazil, 2006. The chi-squared test was used for comparisons between proportions. Non-conditional logistic regression was used for multivariate analysis, with robust adjustment for variance. A total of 1,327 adults were interviewed, of whom 9.3% had used antidepressants. Use of antidepressants was significantly associated with female gender (OR: 2.45; 95%CI: 1.50-4.02), higher socioeconomic status (OR: 2.07; 95%CI: 1.28-3.34), and unemployment (OR: 1.65; 95%CI: 1.06-2.55). The prevalence of antidepressant use was higher than in other studies. Identification of individual determinants of use can serve as the basis for strategies to decrease the consumption of antidepressants in these groups.

OBJETIVO: Verificar a prevalência de sintomatologia depressiva em adolescentes entre 11 e 15 anos em Pelotas, RS, e identificar seus fatores associados. MÉTODOS: Estudo transversal de base populacional com amostra representativa de adolescentes da zona urbana da cidade de Pelotas, RS. Dos 448 setores censitários existentes no município, 79 foram aleatoriamente sorteados. Os jovens entre 11 e 15 anos localizados nestes setores foram convidados a responder o questionário auto-aplicado que continha perguntas sobre: idade, sexo, vida escolar, religião, atividades físicas, entretenimento, tabaco, consumo de álcool, uso de outras drogas, relacionamentos sexuais e conduta. Além disso, a sintomatologia depressiva dos adolescentes foi avaliada por meio da escala Children's Depression Inventory (CDI), também presente no instrumento de pesquisa. Para a análise dos dados foi utilizada a regressão logística ajustada ao modelo hierárquico. RESULTADOS: A prevalência de depressão foi de 2,1%. Após a regressão logística ajustada ao modelo hierárquico, estiveram significativamente associados à depressão: baixa condição socioeconômica, histórico de fracasso acadêmico, ausência de prática religiosa, abuso de álcool nos últimos 30 dias e indicativo de transtorno de conduta. CONCLUSÃO: É evidenciada a necessidade de programas preventivos e integrados de política na adolescência para depressão e comportamentos de risco à saúde.AIM: Verify the prevalence of depressive symptomatology in adolescents aged between 11 and 15 in Pelotas, RS, and identify its associated factors. METHODS: A cross-sectional base-populational study with a representative sample of adolescents of urban area of Pelotas, RS. Among the 448 census tracts in the urban area of Pelotas, 79 were randomly selected. Youths between 11 and 15 years answered a confidential self-report questionnaire on issues such as: age, gender, school life, religion, physical activities, entertainment, tobacco, and alcohol consumption, use of other drugs, sexual relationship and conduct. Children's Depression Inventory (CDI) was used to quantify the depressive symptomatology. Logistic regression was used in the data analysis, which followed a hierarchical model. RESULTS: Prevalence for high depressive symptomatology was 2.1%. After a logistic regression adjusts to a hierarchical model, it was statistically significant associated to: low social economic condition, history of poor academic performance, absence of religious practice, abuse of alcohol in the previous month and indications of conduct disorders. CONCLUSION: It is evidenced the need of preventive and integrative policy programs in adolescence for depression and health risk behaviors.

This study aimed to assess the prevalence of contraceptive use by adolescents. A cross-sectional study was performed from March to September 2002 in a representative sample of adolescents 15 to 18 years of age in the urban area of Pelotas, Rio Grande do Sul State, Brazil. Multiple-stage sampling was used, and in the 448 census tracts located in the urban area, 90 were sampled and households were visited in each tract. Information was collected on sexual initiation and use of contraceptive methods. Chi-square test was used to compare proportions. The sample included 960 adolescents. 88% of subjects reported the use of any contraceptive method. Condoms were the most commonly used method (63.2%). Low adolescent schooling was the only variable associated with increased risk of non-use of contraceptives. Condom use was higher among males, adolescents whose mothers had 9 or more years of schooling, and those reporting several sexual partners in the previous year. Condoms were the most commonly used contraceptive method.O estudo avaliou o uso de métodos contraceptivos em adolescentes. Entre março e setembro de 2002, realizou-se um estudo transversal na zona urbana da cidade de Pelotas, Rio Grande do Sul, Brasil. A amostragem foi em múltiplos estágios, 90 dos 448 setores censitários da zona urbana de Pelotas foram sorteados e em cada setor 86 residências foram visitadas. Considerou-se a informação do adolescente sobre a prática de relações sexuais e do uso de métodos contraceptivos. Nas comparações entre as proporções utilizou-se o teste do qui-quadrado. Foram entrevistados 960 adolescentes, enquanto que para 79 não foi possível realizar a entrevista. Aproximadamente 88% dos adolescentes usavam algum método contraceptivo. O preservativo masculino foi encontrado como o método mais usado naqueles adolescentes que têm relação sexual (63,2%). A escolaridade do adolescente foi a única variável associada com o uso de contraceptivos. O uso de preservativo masculino foi mais freqüente entre os meninos, aqueles cuja mãe tinha nove ou mais anos de escolaridade e naqueles com vários parceiros. O preservativo masculino é o método mais usado.

OBJECTIVE: To assess the prevalence and the factors associated with common mental disorders among adolescents in Pelotas, a southern Brazilian city. METHOD: A population based cross-sectional study was carried out in the urban area of Pelotas. Multi-stage sampling was used to obtain a sample of adolescents aged between 15 and 18 years. Adolescents were interviewed using a self-report confidential questionnaire. The presence of common mental disorders was assessed using the Self-Reporting Questionnaire 20 (SRQ-20). Multivariate analysis was carried out using the Poisson regression with a robust adjustment of variance and control for design effect. RESULTS: Nine hundred and sixty adolescents were interviewed. The prevalence of common mental disorders was 28.8%. Adolescents aged 17 years showed prevalence of 1.37 (95% CI 1.06-1.78) times greater than the 15 year olds. Adolescents whose mothers had between 5 and 8 years of schooling had a prevalence 1.42 (95% CI 1.01-1.51) times greater than those whose mothers had more than 8 years of schooling. Smoking and sedentary behavior were also associated with an increased prevalence of common mental disorders. Those who were dissatisfied with their body image showed a prevalence of 1.47 (95% CI 1.07-2.02). CONCLUSIONS: Maternal schooling, tobacco smoking, sedentary behavior and body image dissatisfaction were factors associated with the presence of common mental disorders.OBJETIVO: Avaliar a prevalência e os fatores associados à presença de transtornos mentais comuns entre adolescentes em Pelotas, uma cidade do sul do Brasil. MÉTODO: Foi realizado um estudo transversal populacional na área urbana de Pelotas. Foi utilizada uma amostragem multi-etapas para obter uma amostra de adolescentes com idades entre 15 e 18 anos. Os adolescentes foram entrevistados utilizando um questionário confidencial auto-aplicável. A presença de transtornos mentais comuns foi avaliada utilizando o Self-Reporting Questionnaire 20 (SRQ-20). Foi realizada análise multivariada por meio de regressão Poisson com ajuste robusto da variância e correção para efeitos de desenho. RESULTADOS: Novecentos e sessenta adolescentes foram entrevistados. A prevalência de transtornos mentais comuns foi de 28,8%. Os adolescentes com 17 anos mostraram prevalência de 1,37 (IC 95% 1,06-1,78) vezes mais alta do que os que tinham 15 anos. Os adolescentes cujas mães tinham entre cinco e oito anos de escolaridade tinham uma prevalência 1,42 (IC 95% 1,01-1,51) vezes mais alta do que aqueles cujas mães tinham mais de oito anos de escolaridade. Tabagismo e comportamento sedentário também foram associados à maior prevalência de transtornos mentais comuns. Aqueles que estavam insatisfeitos com sua imagem corporal tiveram uma prevalência de 1,47 (IC 95% 1,07-2,02). CONCLUSÕES: Escolaridade materna, tabagismo, comportamento sedentário e insatisfação com a imagem corporal foram fatores associados à presença de transtornos mentais comuns.

Esse trabalho procurou avaliar os fatores associados ao bem-estar psicológico em adolescentes realizando um estudo transversal com amostra representativa (n = 960) com idades entre 15 e 18 anos. Foram visitados 86 domicílios em cada um dos 90 setores censitários sorteados. Um consentimento informado era assinado pelos pais ou responsáveis pelo adolescente antes que ele respondesse a um questionário auto-aplicado. O bem-estar psicológico foi avaliado através de uma escala que continha sete figuras que representavam expressões variando de extrema felicidade até extrema tristeza. O adolescente era solicitado a assinalar aquela figura que mais se assemelhava à maneira como se sentia a respeito da sua vida. Entre os entrevistados 72,33% se consideravam com alto nível de bem-estar psicológico, a prevalência foi maior nas famílias de maior nível sócio-econômico (classe social A ou B) e com maior escolaridade materna. Os resultados também mostraram que pessoas que mantém uma prática religiosa, não fumam, não consomem bebidas alcoólicas e que desejam emagrecer tem maior bem-estar psicológico, sugerindo uma inter-relação entre os comportamentos de saúde.This study aimed to evaluate the factors associated with psychological well-being among adolescents in a southern Brazilian city. A cross-sectional study was performed with a representative sample (n = 960) of adolescents (15-18 years). Eighty-six households were visited in each of the 90 randomized census tracts. Parents signed a written consent form before the adolescent answered a self-reported questionnaire. Psychological well-being was evaluated with a scale containing seven figures representing expressions varying from extreme happiness to extreme sadness. Adolescents were asked to mark the figure that best resembled the way they felt about their lives, and 72.33% reported a high level of psychological well-being. Prevalence of psychological well-being was higher in families with better economic status and higher maternal schooling. Adolescents who practiced a religion, did not smoke or consume alcohol, and wished to lose weight showed a higher level of psychological well-being, suggesting an interrelationship between health behaviors.

Este estudo teve o objetivo de examinar a relação entre gênero e utilização de substâncias psicoativas entre adolescentes (consumo de bebidas alcoólicas, fumo e uso de drogas ilícitas). Em 2002 foi realizado um estudo transversal na área urbana de Pelotas, extremo-sul do Brasil. Foi empregada amostragem em múltiplos estágios para se obter uma amostra de adolescentes entre 15 e 18 anos de idade. As entrevistas foram realizadas com questionário auto-aplicado. Tabagismo foi mais prevalente entre as meninas, enquanto o consumo de bebida alcoólica no mês anterior às entrevistas foi maior entre os meninos. Por outro lado, a proporção de adolescentes que relataram uso de drogas ilícitas no mês que antecedeu as entrevistas não esteve relacionada ao gênero. O maior consumo de tabaco entre meninas que entre meninos pode indicar risco de expansão do consumo desta substância por mulheres de outras faixas etárias em gerações futuras, o que justifica preocupação e esforços específicos.This study assesses the relationship between gender and use of psychoactive substances (alcohol, nicotine, and illicit drugs) by teenagers. In 2002, a cross-sectional study was carried out in the urban area of Pelotas, southern Brazil. Multi-stage sampling was used to obtain a sample of adolescents, 15 to 18 years of age. Subjects were interviewed using a self-applied confidential questionnaire. Smoking was more prevalent among girls, while alcohol consumption in the previous month was more common among boys. Meanwhile, the proportion of adolescents that reported drug use in the previous month was unrelated to gender. Higher cigarette consumption by girls suggests an increase in smoking by women in the future, which highlights the need for a special focus on this area.

CONTEXT AND OBJECTIVE: Diabetes is a public health problem and good glycemic control is able to prevent or contain its complications. Self-efficacy is a key factor in successfully achieving behavior goals. The aim of this study was to analyze the psychometric properties of the insulin management diabetes self-efficacy scale (IMDSES) on type 1 diabetes patients from southern Brazil. DESIGN AND SETTING: Validation study in two cities in southern Brazil. METHODS: The psychometric properties of IMDSES were evaluated in a population of type 1 diabetes patients (n = 213), from September to December 2004, who were attended within the Brazilian public healthcare system. Principal component analysis was conducted to develop the subscales. Cronbach’s alpha was used as the reliability coefficient. RESULTS: The analysis of psychometric properties resulted in an IMDSES consisting of 20 items and three subscales: diet (alpha: 0.83), insulin (alpha: 0.92) and general management (alpha: 0.78) and accounted for 53% of the variance. Criteria validity was investigated through two parameters: glycohemoglobin, which showed significant association with self-efficacy on the insulin subscale (p = 0.04), and the variable "adherence", which was significantly associated with self-efficacy on two subscales (p < 0.05). CONCLUSIONS: This study shows that the IMDSES is valid and reliable, and can be used to measure results from diabetes educational programs and to measure self-efficacy relating to diabetes management, for possible interventions.

Background: Breastfeeding has clear short-term benefits, but its long-term consequences on human capital are yet to be established. We aimed to assess whether breastfeeding duration was associated with intelligence quotient (IQ), years of schooling, and income at the age of 30 years, in a setting where no strong social patterning of breastfeeding exists. Methods: A prospective, population-based birth cohort study of neonates was launched in 1982 in Pelotas, Brazil. Information about breastfeeding was recorded in early childhood. At 30 years of age, we studied the IQ (Wechsler Adult Intelligence Scale, 3rd version), educational attainment, and income of the participants. For the analyses, we used multiple linear regression with adjustment for ten confounding variables and the G-formula. Findings: From June 4, 2012, to Feb 28, 2013, of the 5914 neonates enrolled, information about IQ and breastfeeding duration was available for 3493 participants. In the crude and adjusted analyses, the durations of total breastfeeding and predominant breastfeeding (breastfeeding as the main form of nutrition with some other foods) were positively associated with IQ, educational attainment, and income. We identified dose-response associations with breastfeeding duration for IQ and educational attainment. In the confounder-adjusted analysis, participants who were breastfed for 12 months or more had higher IQ scores (difference of 3·76 points, 95% CI 2·20–5·33), more years of education (0·91 years, 0·42–1·40), and higher monthly incomes (341·0 Brazilian reals, 93·8–588·3) than did those who were breastfed for less than 1 month. The results of our mediation analysis suggested that IQ was responsible for 72% of the effect on income. Interpretation: Breastfeeding is associated with improved performance in intelligence tests 30 years later, and might have an important effect in real life, by increasing educational attainment and income in adulthood.
