Abstract Objective To evaluate the association between the dietary patterns (DPs) of pregnant women with GDM (gestational diabetes mellitus) and the birth weight (BW) of the infants. Methods Cross-sectional study with 187 adult pregnant women with GDM attended at a maternity in Rio de Janeiro from 2011 to 2014. Dietary intake was assessed in the third trimester using a semiquantitative food frequency questionnaire (FFQ). The outcomes were BW and weight adequacy for gestational age (GA). Reduced Rank Regression (RRR) was used to explain the following response variables: density of carbohydrates, fibres, and saturated fatty acids. Statistical analyzes included multinomial logistic regression models. Results The mean BW was 3261.9 (± 424.5) g. Three DPs were identified, with DP 3 (high consumption of refined carbohydrates, fast foods/snacks, whole milk, sugars/sweets, and soft drinks and low consumption of beans, vegetables, and low-fat milk and derivatives) being the main pattern, explaining 48.37% of the response variables. In the multinomial logistic regression analysis no statistically significant association was found between the tertiles of DPs and BW or the adequacy of weight for GA, even after adjustments of confounding covariates. Conclusion No significant associations were found between maternal DPs in the third trimester of pregnancy and infant BW or adequacy of weight for GA.

To describe the profile of infants attended at a physical therapy outpatient clinic for discharged patients from the neonatal intensive care unit of Santa Casa de Uruguaiana (Rio Grande do Sul, Brazil). This is a quantitative, observational, and cross-sectional study. The following variables were included: sex, date of birth, gestational age, birth weight, type of delivery, neonatal complications, as well as age and clinical history of the mother. The Alberta Infant Motor Scale was used to assess motor performance. The sample consisted of 49 infants (67.3% males) discharged from the NICU. Univariate analysis indicated a higher risk of atypical motor development among boys (PR: 1.15, p = 0.33). The infants in our sample had more than one risk factor associated with motor development, and the greater the cumulative effect of the risks, the higher the chances of having unfavorable outcomes.

Abstract Objectives: to estimate the correlation between birth weight, breastfeeding, and body mass index in six-year-old children in the city of Palhoça/SC, Brazil. Methods: a cross-sectional study involving 502 children. Data were collected through interviews with mothers at home and anthropometric assessments at schools. The child’s current body mass index was the dependent variable. The independent variables were birth weight, breastfeeding duration, and exclusive breastfeeding duration. Correlations among variables were estimated using Pearson’s correlation coefficient and respective coefficients of determination. Multiple linear regression analysis was performed to observe the independence among the variables. Results: birth weight and body mass index at six years of age showed a statistically significant positive correlation (r= 0.115; p=0.008). Breastfeeding duration was not correlated (r= -0.018; p=0.683). The duration of exclusive breastfeeding showed a statistically significant negative correlation (r= -0.103; p=0.018). However, multiple linear regression analysis showed an independent and significant positive correlation only between birth weight and body mass index at six years of age (r= 0.142; p= 0.003). Conclusion: higher birth weight was significantly and independently positively correlated with increased body mass index at six years of age.

Abstract Objectives: to assess the association between pregnant women’s consumption of ultra-processed foods and newborn body weight. Methods: prospective study with pregnant women (n=214) selected from all Basic Health Units in the city of Pinhais, Paraná. Socioeconomic, demographic, and health data were collected. Food consumption data were assessed using a 24-hour dietary recall and tabulated with GloboDiet software. Daily relative energy intake of ultra-processed food was estimated and logistic regression analysis was utilized. The infuence of covariates on the association analysis was also explored (e.g., income and education). Results: ultra-processed foods contributed to 26.9% of pregnant women’s total energy intake. About 5.7% of newborns were classifed as small-for-gestational-age and 10.7% as large-for-gestational-age. A borderline statistically signifcant association was observed between large-for-gestational-age newborn weight and maternal consumption of ultra-processed foods (OR= 1.027; p=0.048). Additionally, family income was associated with the consumption of ultra-processed foods (OR= 0.144; p=0.008). With each additional 1% consumption of ultra-processed foods, mothers’ likelihood of having large-for-gestational-age babies increased by about 2.7%. Conclusions: the study reveals a trend of positive association between the weight of large-for-gestational-age newborns and the consumption of ultra-processed foods by pregnant women, but not for small-for-gestational-age children.

Objectives: To compare motor, cognitive and language development and affordances (opportunities) in the home environment of infants at biological risk for exposure to HIV and infants not exposed to the virus living in the Metropolitan Region of Belém. Methods: This is a cross-sectional observational study involving 80 infants aged between 4 and 18 months, 43 of them with vertical exposure to HIV. Child development was assessed using the Bayley III Scale, home environment using the Brazilian version of the Affordances in the Home Environment for Motor Development questionnaire - Infant Scale, and economic class using the Brazil Economic Classification Criteria. Student's t test for independent samples was used. Results: Infants had adequate development conditions (Apgar score 1st and 5th minute, weight and length at birth). The predominant economic class was D-E for both groups. There was no difference between infants exposed and unexposed to HIV in motor, cognitive and language development, and in opportunities in the home environment. Conclusion: Infants with biological risk for HIV, when compared to their unexposed peers and up to 18 months of age, did not show differences in motor, cognitive and language performance, nor in relation to opportunities in the home environment.

Abstract Objectives To evaluate the performance of Intergrowth-21 st (INT) and Fetal Medicine Foundation (FMF) curves in predicting perinatal and neurodevelopmental outcomes in newborns weighing below the 3rd percentile. Methods Pregnant women with a single fetus aged less than 20 weeks from a general population in non-hospital health units were included. Their children were evaluated at birth and in the second or third years of life. Newborns (NB) had their weight percentiles calculated for both curves. Sensitivity, specificity, positive (PPV) and negative predictive value (NPV), and area under the ROC curve (ROC-AUC) for perinatal outcomes and neurodevelopmental delay were calculated using birth weight < 3rd percentile as the cutoff. Results A total of 967 children were evaluated. Gestational age at birth was 39.3 (± 3.6) weeks and birth weight was 3,215.0 (± 588.0) g. INT and FMF classified 19 (2.4%) and 49 (5.7%) newborns below the 3rd percentile, respectively.

ABSTRACT Objective: To evaluate the relationship between birth weight and the autonomic nervous system in adulthood through a systematic review. Data source: This is a systematic review of publications without limitation of year and language. We included studies involving the autonomic nervous system and birth weight in adults. Manuscripts were selected based on electronic searches of Medical Literature Analysis and Retrieval System Online (MEDLINE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science Cochrane Library and Scopus databases, using “Autonomic Nervous System” OR “Heart Rate” OR “Heart Rate Variability” AND “Birth Weight” as a search strategy. This review is registered on the International Prospective Register of Systematic Reviews — PROSPERO (ID: CRD42020165622). Data synthesis: We found 894 articles; 215 were excluded for duplicity. Of the remaining 679 studies, 11 remained. Two were excluded because they did not specifically treat the autonomic nervous system or birth weight. There were nine publications, two cohort and seven cross-sectional studies. The main findings were that extreme, very low, low or high birth weight may have some impact on the autonomic nervous system in adult life. Conclusions: Birth weight outside the normality rate may have a negative influence on the autonomic nervous system, causing autonomic dysfunction and increasing the risk of cardiovascular diseases in adult life. Thus, the importance of the follow-up of health professionals from pregnancy to gestation and throughout life, with preventive care being emphasized.

Objective: To investigate whether children with premature birth (PB) and/or with low birth weight (LBW) have different tooth eruption patterns than those born at term or with normal weight. Material and Methods: Searches were performed in the PubMed, Cochrane Library, Sc1opus, Web of Science, LILACS, and BBO databases as well as the grey literature. Three independent reviewers were involved in study selection, data extraction, and bias assessment. The risk of bias was assessed using the Modified Newcastle-Ottawa Scale. Meta-analysis was conducted to compute the mean difference (MD) in mean chronological or adjusted age at the eruption of the first deciduous tooth between preterm children and those born at full term. The GRADE approach was used. Results: Among a total of 316 articles identified, 21 were eligible for inclusion and three were included in the meta-analysis. PB was associated with the delay in the first tooth deciduous eruption when chronological age was considered (MD: 1.36; 95%CI: 1.02–1.69) but not when considering adjusted age (MD: -0.30; 95%CI: -0.67–0.07). The evidence was graded as having very low quality. Conclusion: Based on a low certainty of evidence the PB is associated with the delayed eruption of the first deciduous tooth when considering chronological age but not when adjusted age is considered.

Abstract Objectives: to assess the prevalence of maternal gestational anemia and its association with the birth weight. Methods: retrospective longitudinal observational study in a cohort of 370 pregnant women. Anthropometric, biochemical, ginecobstetric and sociodemographic data of both mothers and newborns were evaluated. The results of maternal erythrocyte indices were analyzed and contrasted with newborns anthropometrical data. Results: the mean age of the pregnant women was 27±6 years, with a mean gestational age of 32±6 weeks at the assessment moment, 56.2% were overweight. The prevalence of anemia was 28.6%. 47.2% women with anemia and 36% women without anemia had low birth weight/very low birth weight newborns (p=0.009). Of the children born to mothers with iron deficiency anemia, 20% had low birth weight and 15% very low birth weight. 54.3% newborns with global undernutrition or at risk of developing it were born to women with underweight(p=0.046), in addition, the higher the maternal weight, the lower the number of term newborns with risk of short height (p

ABSTRACT OBJECTIVE To investigate the association between birth weight and bone mineral content (BMC), and whether this relationship differs between men and women. METHODS A total of 10,159 participants from the ELSA-Brasil cohort were eligible for this analysis. The outcome was the z-score of the ratio BMC (kg)/height (m). The exposure was the low birth weight (< 2.5kg). The magnitude of the associations was estimated by mean differences and their respective 95% confidence intervals (95%CI) using linear regression. All analyses were presented for the total population and stratified by sex. RESULTS Most were women (54.98%), and the mean age was 52.72 years (SD ± 6.6). In the crude model, we observed that low birth weight was associated with a lower mean BMC/height z-score, compared to adequate birth weight (mean difference: −0.30; 95%CI: −0.39 to −0.21), and this effect was stronger in men (mean difference: −0.43; 95%CI: −0.56 to −0.30) than in women (mean difference: −0.31; 95%CI: −0.44 to −0.19). After adjusting for age, sex per total population, race/skin color, maternal education, individual education, and current weight, there was a considerable reduction in the magnitude of the association (total population: −0.10; 95%CI: −0.14 to −0.06; men: −0.13; 95%CI: −0.21 to −0.06; women: −0.13; 95%CI: −0.21 to −0.05). CONCLUSION Low birth weight is related to BMC/height z-score in both sexes with no indication of differences by sex. The magnitude of the associations was attenuated after adjustment for the current weight.

Objectives. To determine the prevalence of maternal death, stillbirth and low birthweight in women with (pre-) eclampsia and complicated pregnancies or deliveries in Centre de Références des Urgences Obstétricales, an obstetric emergency hospital in Port-au-Prince, Haiti, and to identify the main risk factors for these adverse pregnancy outcomes. Methods. We conducted a retrospective cohort study of pregnant women admitted to Centre de Référence des Urgences Obstétricales between 2013 and 2018 using hospital records. Risk factors investigated were age group, type of pregnancy (singleton, multiple), type of delivery and use of antenatal care services. Results. A total of 31 509 women and 24 983 deliveries were included in the analysis. Among these, 204 (0.6%) maternal deaths (648 per 100 000 women giving birth), 1962 (7.9%) stillbirths and 11 008 (44.1%) low birthweight neonates were identified. Of all admissions, 10 991 (34.9%) were women with (pre-)eclampsia. Caesarean section significantly increased the risk of maternal death in the women with a complicated pregnancy and women with (pre-)eclampsia, but reduced the risk of stillbirth in such women. Not attending antenatal care was associated with a significantly higher risk of stillbirth (odds ratio (OR) 4.82; 95% confidence interval (CI) 3.55–6.55) and low birthweight (OR 1.40; 95% CI 1.05–1.86) for women with complicated pregnancies. Conclusion. To prevent and treat pregnancy complications as early as possible, antenatal care attendance is crucial. Improving the quality of and access to antenatal care services and providing it free to all pregnant women in Haiti is recommended.

Objective: to describe the profile of indications, comorbidities and early postoperative complications of children and adolescents undergoing tracheostomy in a Brazilian referral hospital. Method: retrospective, cross-sectional and quantitative study, with analysis of electronic medical records of children and adolescents who underwent tracheostomy in a hospital in Botucatu, São Paulo, Brazil, from 2013 to 2019. The sample was compared by dividing the presence and absence of post-operative complications. early operative procedures, with regard to sex, age, syndrome, death, elective or urgency/emergency character and birth weight. Results: among 100 records, 55% were male, with an average of 3.03±3.10 years. Twelve different syndromes were identified in 16 patients. With regard to early postoperative complications, cork was the most frequent (13%) and was associated with the presence of syndromes (p=0.01). The most identified reason for tracheostomy was prolonged orotracheal intubation, while 44% died due to the severity of the underlying disease. Conclusion: pediatric tracheostomy is a safe procedure, more frequently realized due to failure of extubation, in genetic syndrome children younger than one year old. Cork is a frequent complication, associated to syndromes. [ABSTRACT FROM AUTHOR]

Abstract Objectives: to determine the relationship between maternal hemoglobin (HbM) per gestational trimester and birthweight (BW). Methods: this was an analytical, cross-sectional observational study that included the prenatal records of494 pregnant women who delivered live newborns in the Department of Antioquia. The maternal health data collected included HbM and BW, and gynecological and obstetric, anthropometric, and maternal health-related data. The Mann-Whitney U test was applied, supplemented by effect size (ES) to compare the study groups. Results: HbMin the third trimester was significantly associated with BW (p=0.029).It showed a significant effect size on BW as follows: first trimester: ES=0.44 (CI95%= 0.183-0.697); second trimester: ES=0.49 (CI95%= 0.187-0.79); and third trimester: ES=0.43 (CI95% = 0.202-0.658). Maternal anemia was 4.2%>, 11.2%, and 21.4%> in the first, second, and third trimester, respectively. Conclusions: as it is an inexpensive indicator and easy to determine, the timely monitoring and assessment of HbM is required owing to its importance in maternal and neonatal health, quality of life, and human capital development.

Abstract Objectives: to perform a systematic review of studies that investigated the influence of ultra-processed foods (UPF) consumption during pregnancy on child’s anthropometric parameters up to one year of life. Methods: cohort and cross-sectional studies were researched in BVS, Cinahl, Cochrane, Embase, Pubmed, Scopus and Web of Science databases until March 2020, and the main descriptors were: “Pregnant Women”, “Ultra-processed foods”, “Birth Weight”, “Smallfor Gestational Age”, “Infant”, “Newborn”. Results: seventeen articles were considered eligible and evaluated the associations between the exposures: ultra-processed dietary patterns; soft drinks, sugar-sweetened beverages, artificially sweetened beverages; fast food, junk food, sweets, snacks and the outcomes: birth weight and its classifications; length and head circumference at birth; birth weight adjustments according to gestational age; weight/age, length/age, body mass index/age and weight/length indices. The results showed: 36 non-significant associations between the exposures and the outcomes; 13 direct associations (outcomes versus ultraprocessed dietary patterns, soft drinks, artificially sweetened beverages, sweets, junk food) and 5 inverse associations (outcomes versus ultra-processed dietary patterns, soft drinks). Conclusions: most of the evaluated literature did not demonstrate the influence of UPF consumption during pregnancy on the newborn’s anthropometric measurements up to one year of life and denoted a smaller number of direct and inverse associations between the exposures and the outcomes.

Objective: To analyze the epidemiological profile of low birth weight newborns according to pre and perinatal data, according to the Information System on Live Births (SINASC) in the State of Pernambuco. Method: This is a descriptive and transversal study, using secondary data referring to the year 2017. The dependent variable was low birth weight, while the independent variables were maternal age, level of education, prenatal consultations, prematurity and Apgar. Results: Mothers aged 45 to 49 years and adolescents aged 10 to 14 years, no maternal education, number of consultations 1 to 3 or none, prematurity and Apgar < 7 in the first and fifth were found to have a high percentage of low birth weight. Conclusion: The profile of low birth weight newborns was related to prenatal and peri-natal variables.

The oropharyngeal administration of colostrum in preterm newborns may offer immunological benefits through the contact of protective biofactors with oropharyngeal-associated lymphoid tissue. The objective was to elucidate the influence of maternal colostrum administration in the oropharynx of premature babies with clinical suspicion of early neonatal sepsis. We selected twenty newborns, admitted to the Neonatal Intensive Care Unit (NICU) of a public hospital during the study period. Raw colostrum was placed on the oropharyngeal mucosa until the 5th day of life. Blood samples were collected to complement the diagnosis. The study concluded that newborns who received oral colostrum in the first days of life reached birth weight faster than babies who did not. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the present study was to evaluate the prevalence of active and passive smoking during pregnancy and its association with sociodemographic indicators, as well as perinatal and postnatal outcomes in newborns. Methods: This cross-sectional study was comprised of 431 pairs of mothers/ newborns. The study variables were: preterm birth, birth weight, oral mucosal lesions, sociodemographic indicators and smoking data. We collected data from medical records and through a self-administered questionnaire answered by mothers. A pediatric dentist examined the newborns for oral mucosal lesions. Bivariate and multivariate logistic regression models were used to evaluate the association between active and passive smoking and the other variables (α=5%). Results: The prevalence of active (9.5%) and passive smoking (4.2%) during pregnancy was low. Active smoking was statistically associated with low birth weight (OR: 2.4; 95%CI:1.1-5.3), lower schooling level (OR: 0.2; 95%CI:0.1-0.5) and mothers aged ≥36 years old (OR: 4.9; 95%CI:1.2-20.0). Passive smoking was not statistically associated with the other variables. There was no association between active or passive smoking during pregnancy and premature birth and oral lesions of the newborn. Conclusions: The prevalence of active and passive smoking were low. Active smoking was associated with low birth weight, maternal age and mother's schooling, suggesting a social influence of smoking behavior among a population with a lower educational level. There was no association between active and passive smoking and prematurity and oral lesions of the newborn.

Abstract Objectives: to identify trendand factors associated with adverse birth weight. Methods: cross-sectional design. The analysis uses the 2009-2015 Uruguay Perinatal Computer Systemdata on 303,625 newborns. Results: the prevalence of macrosomia (> 3,999g) has increased from 7.0% to 8.4%. The prevalence of low birth weight (LBW) (< 2,500g) decreased, standing at 6.6% in the last year. The factors that determines more possibilities of LBW were preeclampsia (OR = 4.80; CI95%= 4.57-5.05), inadequate controls (OR = 2.29; CI95%= 2.20-2.39), shorter duration of pregnancy (OR = 2.52; CI95%= 2.50-2.55), previous hypertension (OR = 2.11; CI95%= 1.96-2.27), hypertensive disease of pregnancy (OR = 1.82; CI95%= 1.74-1.90), low prematernal maternal weight (OR = 1.65; CI95%= 1.58-1.74). Macrosomia was associated with type 1 diabetes (OR = 2.21; CI95%= 1.86-2.61), Type 2 or Gestational (OR = 1.78; CI95%= 1.70-1.87), obesity maternal (OR = 2.33; CI95%= 2.24-2.43) and longer gestation duration (OR = 2.62; CI95%= 2.53-2.72). Conclusions: the LBW decreases while the macrosomia increases. The health and nutritional status of women at the beginning of pregnancy, pathologies of the last trimester, smoking, shorter duration of pregnancy and inadequate controls are associated with BPN. Overweight, obesity and metabolic diseases determine macrosomia.

Objective: To identify the type of feeding and analyze the sociodemographic and clinical factors associated with exclusive breastfeeding at hospital discharge, in the first and in the last follow-up visit of the third stage of the Kangaroo Mother Care among infants admitted to the kangaroo unit., Method: Longitudinal and retrospective study. A total of 186 infants of gestational age <37 weeks admitted to the kangaroo unit in 2018 and 2019 was included. Data collected from medical records and subjected to inferential analysis and the Poisson regression model (P < 0.05)., Results: Exclusive breastfeeding rate was 73.1% at discharge, with a drop at the last follow-up visit (68.1%). At discharge, there was a greater probability of exclusive breastfeeding in younger mothers, with higher education, infants born with higher birth weight and who received exclusive human milk during hospitalization; in the first follow-up visit, in a younger mother and infant who received only human milk during hospitalization; and in the last follow-up visit, a young mother, infant who received only human milk and suckled at the breast for the first time in the kangaroo unit., Conclusion: Most infants hospitalized in the second stage of the Kangaroo Mother Care were exclusively breastfed and presented maternal and clinical factors related to breastfeeding. This fact can help manage the challenges of the method and promote breastfeeding.

Objective: To know the profile of newborns hospitalized in the Intermediate Neonatal Care Unit and associate maternal and neonatal factors with the length of hospitalization. Methods: Cross-sectional, documentary research, carried out in a university hospital in the South Region of Brazil, with 384 newborns hospitalized. A descriptive analysis and the chi-square test were performed. Results: Most hospitalizations occurred in the early neonatal period, of male babies, white ethnicity, gestational age 36 weeks, weight 2,690g, Apgar score 6.77 in the first and 8.49 in the fifth minute, and average days of hospitalization 8.49. Prolonged period of hospitalization was associated with maternal intercurrence, prematurity, low birth weight, male gender, use of antibiotics and weight gain. Conclusion: Reaffirms the importance of knowing the causes of hospitalization of newborns and understanding the profile of illness in the neonatal period, to subsidize public policies and quality assistance to reduce hospitalization and perinatal morbidities.

Abstract: This study aimed to compare the anthropometric measurements and body proportionalities of neonates born before the Zika virus epidemic with those born during this period. We compared 958 neonates born during the pre-Zika epidemic with 264 neonates born during the epidemic period. The newborns had their head circumference, weight, and length classified according to the Fenton & Kim growth chart. We considered disproportionate those individuals that presented microcephaly and adequate weight or length for sex and gestational age, and those whose head circumferences were lower than the ratio ((length / 2) + 9.5) - 2.5cm. We estimated the frequencies of Zika positivity and brain imaging findings among neonates with microcephaly born during the epidemic period, concerning the anthropometric and body proportionality parameters. Low weight and proportionate microcephaly were similar among newborns from both periods. However, the frequencies of newborns with microcephaly with a very low length and disproportionate microcephaly were higher among the neonates of the epidemic period with brain abnormalities and positive for Zika virus. We conclude that, at birth, the disproportion between head circumference and length can be an indicator of the severity of microcephaly caused by congenital Zika.

The objective of this meta-analysis was to evaluate the effects of weight loss or weight gain of beef cows during the second and/or third trimester of gestation on the postnatal performance of the progeny. The variation in cow weight during the gestational period was calculated to standardize the treatments, being them: severe loss (SL = cows that lost more than 10% of weight); moderate loss (ML = cows that lost from 0 to 10% of weight) and weight gain (WG = cows that gained weight). The intensity of the cow weight variation effect was calculated as the mean difference (MD) with a 95% confidence interval and heterogeneity determined using the Q test and the I2 statistic. A meta-analysis of random effects was conducted for each indicator separately with the means of the control and experimental groups. Calves from WG cows were higher for birth weight (P = 0.0094); weight adjusted to 205 days (P = 0.0127) and average daily gain during pre-weaning (P < 0.0001) in relation to calves from ML cows. The W205 of calves from SL cows was 11.6 kg lower than the progeny from ML cows. The post-weaning performance of the progeny tended (P = 0.0868) to be higher in the progeny of WG cows than ML ones. The weight gain of beef cows during gestation improves the pre- and post-weaning performance of the progeny, with more evident effects in the early months of life of the offspring.

Objective: Knowing the maternal and neonatal factors related to perineal integrity and relating perineal integrity to the professional attending the delivery. Methods: Retrospective, descriptive, quantitative study on medical records of 292 women who had vaginal delivery with intact perineum. Including women who had a vaginal delivery with intact perineum, full-term fetus, single or multiple, started spontaneously or induced, instrumentalized or not, regardless of obstetric risk. The variables used were race, maternal age, gestational age, parity, number of fetuses, use of oxytocin in conducting labor, use of analgesia, spontaneous or induced labor, presentation and weight of the newborn at birth, maternal position in the expulsive and professional who attended the birth. Results: The majority of women with intact perineum were brown, multiparous with spontaneous births; oxytocin and analgesia rate was 11,6% and 19,9%, respectively; the average weight of newborns was 3176g and obstetric nursing was present in more than 90% of deliveries. Conclusion: Race and multiparity remained as protective factors against perineal lacerations, while other variables need further studies to determine their role in perineal integrity. Obstetric Nursing has remained an indicator of good practices in childbirth and birth. [ABSTRACT FROM AUTHOR]

This article aims to propose the use and / or adequacy of quality tools in health management, based on data from the Live Birth Information System (SINASC). Thus, it's intended to infer about the determinants of Low Birth Weight (LBW) and based on these evidences, suggest the use of quality tools in the control and continuous monitoring of prenatal care. For this purpose, binary choice regression models were used, together with the main quality tools discussed in the literature. Through this diagnosis, we seek to demonstrate the good adequacy of quality tools in different sectors to the industrial, in particular to the Health Sector, focusing on prenatal care.

In the practice of beekeeping it is generally accepted that the colony production is directly related to the quality of the queen. Of all the possible variables related to such quality, birth weight is considered one of the most useful. In our study we have looked the effect of the breeding colony of the local bee subspecies (Apis melífera iberiensis Engel), on the weight of the new queens at birth, and the weight of the wax cells in which they were reared. To carry out the breeding we have used the Doolittle method, a procedure widely used by beekeepers. Between the months of March and May of 2019, we raised 140 queens, carrying out eight breeding cycles and using four different hives. The mean weight of the queens at birth was 194 ± 26 mg (x ± SD), and that of the brood cells 604 ± 125 (x± SD). The results obtained did not show significant differences between the brood hives, for the weight variable of the queens at birth, but there were differences in the case of the variable weight of the queen cells.

Birth weight is an important predictor of perinatal, infant, and preschool-age children morbimortality. However, information about indigenous children’s birth weight is still scarce. This study aimed to analyze the birth weight of indigenous children based on data from the First National Survey of Indigenous People’s Health and Nutrition, Brazil (2008-2009). This is the first study to address indigenous children’s birth weight based on a nationwide representative sample. Mean birth weights and the respective standard deviations were calculated according to geopolitical region, sex, type of birth, and birthplace. The chi-square test was used to analyze differences in proportions, and Kruskal-Wallis and Mann-Whitney U tests in means, considering sample design and data normality. We found no records on birth weight in the researched documents for 26.7% of the 6,128 sampled children. The mean birth weight for the 3,994 children included in the analyses was 3,201g (standard deviation - SD ± 18.6g), regardless of sex, type of birth, and birthplace. The prevalence of low birth weight was 7.6% (n = 302) and was significantly higher among girls. Boys presented significantly higher mean birth weight than girls, regardless of the geopolitical region. Low birth weight was slightly less frequent among indigenous children when compared to Brazilian children in general. Our study indicates the need to improve prenatal care and the quality of consultation records for indigenous women as a strategy to promote safe pregnancy and childbirth.

ABSTRACT Objective: To verify the association of anthropometric parameters at birth, socioeconomic and biological variables, physical activity, and parental nutritional status with overweight and abdominal obesity in adolescents. Methods: A cross-sectional study was carried out on 39 public and private schools in Recife (state of Pernambuco, Brazil). The sample consisted of 1,081 teenagers aged from 12 to 17 years. Data were collected from the Study of Cardiovascular Risks in Adolescents (ERICA). Body mass index according to age (BMI-for-age), waist circumference (WC), and waist-to-height ratio (WtHR) were considered as outcome variables, whereas the explanatory variables were birth weight, Röhrer’s Ponderal Index (RPI), biological and socioeconomic variables, physical activity, and parental nutritional status. The crude and adjusted prevalence ratios (PR) for the studied association were estimated by Poisson Regression. Results: The multivariate Poisson regression showed that the variable that remained significantly associated with overweight in adolescence was maternal overweight, PR=1.86 (95% confidence interval [95%CI] 1.09-3.17). High birth weight also remained significantly associated with abdominal obesity assessed by WC, PR=3.25 (95%CI 1.0-9.74). Conclusions: High birth weight may be a marker for abdominal obesity in adolescence; and high maternal BMI, for overweight.

Background: Gestational Diabetes Mellitus (GDM) is a glucose tolerance disorder that first appears during pregnancy. GDM can cause a variety of obstetric and perinatal complications for pregnant women and their fetuses. The prevalence of GDM in the city of Surabaya in 2015 amounted to 2.29%, increasing to 3.88% in 2018. Aim: The purpose of this study was to analyze the determinants (family history of diabetes mellitus, BMI, history of birth weight, parity, and the age of the pregnant woman) that influence the GDM. Methods: This research is an analytical study with an observational approach. The research design was carried out using a case-control study. In this study, the number of samples was 36 people, 6 cases, and 30 people as controls, and were taken randomly. The data source obtained from secondary data (medical records of pregnant women) at Mulyorejo Health Center Surabaya. The analysis used in this study was a simple logistic regression test. Results and Discussion: The result showed an effect of a family history of diabetes mellitus (p = 0.035) on the incidence of GDM. Parity was a potential variable (p = 0.077) on the incidence of GDM. Meanwhile, BMI, history of birth weight, and mother's age did not affect the incidence of GDM. Conclusion: Pregnant women with a family history of diabetes who are not balanced with maintaining a good lifestyle can experience complications of developing GDM. [ABSTRACT FROM AUTHOR]

This study assessed the association of birth weight, gestational age, and intrauterine growth with bone mineral density (BMD) at 22 and 30 years of age in the 1982 and 1993 birth cohorts in Pelotas, Rio Grande do Sul State, Brazil. BMD was measured by dual-energy X-ray absorptiometry (DXA) and the association was assessed using analysis of variance. Multiple linear regression was used to control for confounding factors: sex; household income at birth; maternal smoking during pregnancy; maternal schooling; maternal ethnicity/skin color; and pre-pregnancy body mass index. The study tested whether body fat in adulthood was a mediator of the association analyzed, using the G-computation Formula. A total of 6,803 participants from the 1982 and 1993 cohorts were evaluated at 30 and 22 years of age, respectively. Birth weight was associated with BMD at all sites, with a greater difference at the femoral neck. Individuals born weighing less than 2,000g had on average -0.036g/cm2 (95%CI: -0.064; -0.008) of BMD in the femoral neck than individuals weighing more than 3,500g. Individuals with an intrauterine growth z-score at least 1.28 standard deviation below the mean had an average of -0.013g/cm2 (95%CI: -0.024; -0.002) of BMD in the lumbar spine compared with individuals with an above-average z-score. The mediation analysis showed that body fat in adulthood did not mediate the association. Birth conditions have been associated with BMD in adulthood and the identification of early factors related to bone loss is essential due to the demographic inversion that has been taking place in low- and middle-income countries.

ABSTRACT Objective: To examine the effect of birth weight and subsequent weight gain on children being overweight and obese in serial assessments of Uruguayan children living at urban areas. Methods: We used secondary data of pediatric anthropometric measurements and health and socioeconomic characteristics of families that were included in a longitudinal and prospective nationally representative survey (“Encuesta de Nutrición, Desarrollo Infantil y Salud”). The associations of conditional weight gain, being overweight and obesity were tested through correlation coefficients. Multivariate binary logistic regression models were performed to calculate the effect of birth weight on childhood obesity and were adjusted for covariates. Results: For macrosomic babies, there was an increase in the prevalence of overweight and obesity in 70% compared with non-macrosomic babies, when we adjusted for sex, exclusive breastfeeding duration, and household income. The correlation between weight gain and the body mass index for age indicated that the greatest (positive) difference in Z score between measurements increased the obesity levels. Conclusions: Our findings suggest that ensuring optimal birth weight and monitoring and controlling posterior weight gain represent the first steps toward primary prevention of childhood obesity.

Abstract: A trend towards increasing birth weight has been shown, but factors that explain these trends have not been elucidated. The objectives of this study were to evaluate changes in mean birth weight of term newborns and to identify factors associated with them. All cohorts are population-based studies in which random samples of births (Ribeirão Preto, São Paulo State in 1978/1979, 1994 and 2010; Pelotas, Rio Grande do Sul State in 1982, 1993 and 2004; and São Luís, Maranhão State in 1997/1998 and 2010, Brazil). A total of 32,147 full-term, singleton live births were included. Mean birth weight reduced in the first study period (-89.1g in Ribeirão Preto from 1978/1979 to 1994, and -27.7g in Pelotas from 1982 to 1993) and increased +30.2g in Ribeirão Preto from 1994 to 2010 and +24.7g in São Luís from 1997 to 2010. In the first period, in Ribeirão Preto, mean birth weight reduction was steeper among mothers with high school education and among those born 39-41 weeks. In the second period, the increase in mean birth weight was steeper among mothers with low schooling in Ribeirão Preto and São Luís, females and those born 37-38 weeks in Ribeirão Preto and cesarean section in São Luís. Birth weight decreased in the first study period then increased thereafter. The variables that seem to have been able to explain these changes varied over time.

ABSTRACT: Introduction: Epidemiological studies have shown associations between placental measurements and perinatal and later life outcomes. Objectives: To report placental measurements and evaluate their association with birth weight in a Brazilian birth cohort. Methods: Retrospective cohort study with 958 mothers, placentas, and newborns delivered at the Ribeirão Preto Medical School Hospital, Universidade de São Paulo, Brazil, in 2010 and 2011. The information was collected from interviews, medical records, and pathology reports. The placental measurements were: weight, largest and smallest diameters, eccentricity, thickness, shape, area, and birth weight/placental weight and placental weight/birth weight ratios. We analyzed the associations between birth weight and placental measurements using multiple linear regression. Results: Placental weight alone accounted for 48% of birth weight variability (p < 0.001), whereas placental measurements combined (placental weight, largest and smallest diameters, and thickness) were responsible for 50% (p < 0.001). When adjusted for maternal and neonatal characteristics, placental measurements explained 74% of birth weight variability (p < 0.001). Conclusion: Placental measurements are powerful independent predictors of birth weight. Placental weight is the most predictive of them, followed by the smallest diameter.

Introduction: Birth weight is a major contributor to neonatal morbidity and mortality and is associated with chronic diseases in adulthood. This study aimed to evaluate the use of Intergrowth 21st instead of the Fenton & Kim 2013 growth charts in the diagnosis of small and large for gestational age in a group of Portuguese newborns. Material and Methods: We conducted an analytical and retrospective study to evaluate birth weight of term and preterm newborns using both growth charts. Groups studied: ‘Term-weeks’ and ‘Term-days’ (term newborns with gestational age in weeks and days, respectively), ‘Preterm-weeks’ and ‘Preterm-days’ (preterm newborns with gestational age in weeks and days, respectively). Results: A total of 14 056 newborns were included, 6% preterm. Using the Intergrowth 21st growth charts, the groups ‘Term-weeks’ (n = 12 081), ‘Term-days’ (n = 1118), ‘Preterm-weeks’ (n = 617) and ‘Preterm-days’ (n = 240), classified as small for gestational age according to the Fenton & Kim 2013 growth charts were adequate for gestational age in 52.8%, 57.8%, 37.7% and 9.3% respectively; and 9.2%, 9.2%, 5.9% and 0.6% of adequate for gestational age newborns were large for gestational age, respectively. In the ‘Pretermdays’ group, 7.9% of adequate for gestational age newborns were small for gestational age and 22.2% of large for gestational age newborns were adequate for gestational age, all with gestational age below 231 days. Discussion: The use of the Intergrowth 21st growth charts in this sample resulted in a lower number of newborns being classified as small for gestational age, except in very preterm newborns. Conclusion: Considering the results obtained, we suggest that Portuguese maternity hospitals use the Intergrowth 21st instead of the Fenton & Kim 2013 growth charts. However, more studies are needed to confirm these results.

Abstract Objective To assess 11 formulae commonly used to estimate fetal weight in a population of premature fetuses who had abnormal Doppler velocimetry due to early-onset placental insufficiency. The performance of each formula was evaluated in subgroups of fetuses with expected growth and intrauterine growth restriction. Methods Data were collected fromfetuses andmothers who delivered at three Brazilian hospitals between November 2002 and December 2013.We used the following formulae: Campbell; Hadlock I, II, III, IV and V; Shepard; Warsof; Weiner I and II; and Woo III. Results We analyzed 194 fetuses. Of these, 116 (59.8%) were considered appropriate for gestational age (AGA), and 103 (53.1%) were male. The amniotic fluid volume was reduced in 87 (44.8%) fetuses, and the umbilical artery Doppler revealed absence or inversion of diastolic flow in 122 (62.9%) cases, and the analysis of the ductus venosus revealed abnormal flow in 60 (34.8%) fetuses. The Hadlock formulae using three or four fetal biometric parameters had low absolute percentage error in the estimated fetal weight among preterm fetuses with abnormal Doppler studies who were born within 5 days of the ultrasound evaluation. The results were not influenced by the clinical and ultrasound parameters often found in early-onset placental insufficiency. Conclusion In this study, the formulae with the best performance for fetal weight estimation in the analyzed population were Hadlock I and IV, which use four and three fetal biometric parameters respectively to estimate the weight of preterm fetuses with abnormal Doppler studies.

ABSTRACT OBJECTIVE To evaluate the clinical factors, as well as weight gain, in a group of pregnant women, associating them with fetal macrosomia in a public institution in Antioquia, Colombia, from 2010-2017. METHODS A case-control study, using secondary information registries. Cases were defined using newborn weight of ≥ 4000g, while controls were defined as newborn weight between 3000–3999g. A proportion ratio (PR) was established to evaluate factors associated with macrosomia, and a generalized linear model (GLM) of Poisson regression with robust variance was used to evaluate the aspects that best explained macrosomia in the neonate. RESULTS 122 pregnant women participated in the study, of which 611 were cases and 61 were controls. Of the participants, 44.3% had pre-pregnancy overweight and 48.4% had excess gestational weight gain. Statistically significant differences were found between the groups in the following variables: pre-pregnancy BMI (p = 0.004), gestational weight gain (p = 0.000), gestational diabetes (p = 0.000), and type of delivery (p = 0.004). According to the regression model, a macrosomic newborn is 3.5 times more likely in women with excessive gestational weight gain (95%CI 1.78-7.18) and twice more likely in women who have gestational diabetes (95%CI 1.51-2.76). Of women with pre-pregnancy excess weight, 63% had excess gestational weight gain. CONCLUSIONS Within this cohort, pre-pregnancy BMI, excess weight gain in pregnancy, and the presence of gestational diabetes were associated with an increased risk of neonatal macrosomia. pre-pregnancy BMI and weight gain in pregnancy are modifiable risk factors that are responsive to nutrition interventions, which can minimize adverse perinatal outcomes.

Objective: The management of children with low birth weight is not the same in countries with different resources. The authors assessed the association of birth weight with blood pressure and nutritional status in a representative sample of adolescents from a Brazilian state, aiming to identify possible consequences of these differences. Methods: A cross-sectional school-based study was conducted with adolescents (12-18 years) enrolled in public and private schools. Birth weight, office blood pressure, home blood pressure measurements, and nutritional status (body mass index, height z-score for the age, and waist circumference) were assessed. The association of birth weight with the outcomes (blood pressure, height, body mass index, and waist circumference) was studied through univariate and multivariable linear regression models. Results: A total of 829 adolescents with a mean age of 14.6 ± 1.62 years were included; 43.3% were male, and 37.0% from private schools. The prevalence of low birth weight was 8.7%. Mild low height prevalence was higher among those adolescents with low/insufficient birthweight when compared to those with normal/high birth weight (11.7 vs. 4.2%; p < 0.001). In the multiple linear regression analysis, for each increase of 100 g in birth weight, height increased by 0.28 cm (95% CI: 0.18-0.37; p < 0.01). Birth weight did not influence office blood pressure and home blood pressure, body mass index, or waist circumference of adolescents. Conclusions: Birth weight was directly associated to height, but not associated to blood pressure, body mass index, and waist circumference in adolescents from an urban area of a developing country.

Objective: To compare differences in the motor performance between preterm and full-term infants in the 1st and 2nd months of age and verify the influence of the birth weight in the preterm infants in different postures. Method: Twenty preterm (33.2 ± 3.2 weeks of gestation) and 20 full-term (39.5 ± 1.0 weeks of gestation) infants, with birth weight of 2.130 ± 689 kg and 3.218 ± 479 kg, respectively, were assessed longitudinally from 1 to 2 months of age (corrected for prematurity) using the Alberta Infant Motor Scale (AIMS). Motor performance was compared using t tests. Preterm infants were subdivided into strata according to birth weight and compared using the the Mann-Whitney test. Pearson's correlation test was performed as an exploratory analysis to verify association between motor performance and time of hospitalization stay. Results: There was lower score in the prone subscale for the preterm infants than for the full-term infants in the 2nd month of age. Preterm infants with birth weight of less than 2.500 kg did not present differences in motor performance compared to preterm infants born with higher weight; however, preterm infants with birth weight of less than 1.750 kg underperformed the preterm infants with higher birth weight in both months. There was a moderate negative association between time of hospitalization and motor performance in prone at 2 months. Conclusions: Less stimulation in the prone posture associated with prolonged hospitalization may have limited the development of extensor neck muscles in the preterm infants, specially those with birth weight of less than preterm infants.

Objectives: Birth weight is a parameter used throughout the world to evaluate the health status of the newborn. Thus, the study aimed to analyze the association between birth weight and maternal and obstetric variables in a hospital in the countryside of the state of Ceará, Brazil. Methodology: A quantitative and retrospective study was carried out using secondary data from medical records of parturients attended at a maternity hospital in the city of Sobral, State of Ceará. The data analyzed were dated in 2015. The research was submitted and approved by the Ethics Committee of Universidade Estadual Vale do Acaraú (UVA). Results: In 2015, 1,101 declarations of live births resident in Sobral, state of Ceará, were filled out, all of which are valid as object of study. Birth weight ranged between 2,500g and results lower than the average were considered low weight (LBW). The percentage of neonates with LBW in the period studied was 27.2%. Conclusion: Considering LBW a dangerous and problematic parameter in the current scenario, it is important that pre- and perinatal care be strengthened to effectively prevent and intervene in unfavorable outcomes for mother and child.
