We investigated longitudinal predictors for disordered eating from early adolescence to young adulthood (12-34 years) across gender and different developmental phases among Norwegian young people. Survey data from a population-based sample were collected at four time points (T) over a 13-year time span. A population-based sample of 5,679 females and males at T1 and T2, 2,745 at T3 and 2,718 at T4 were included in analyses, and linear regression and random intercept models were applied. In adolescence, initial disordered eating and parental overprotectiveness were more strongly related to disordered eating among females, whereas loneliness was a stronger predictor for adolescent males. Initial disordered eating during early adolescence predicted later disordered eating more strongly in late- than mid-adolescence. In young adulthood, no significant gender-specific risk factors were found. The findings provide support for both shared and specific risk factors for the developmental psychopathology of disordered eating.

This study aimed to evaluate the effectiveness of the International Child Development Programme (ICDP), a group‐based parenting programme used internationally and implemented nationally in Norway. We used a cluster randomized controlled trial in which 81 groups were randomly assigned to either the intervention or waitlist control condition after the baseline data collection. A total of 590 parents completed at least one of three questionnaires (administrated before and after ICDP and 4 months after completing the intervention). Primary outcomes included parental self‐efficacy, parental emotion sensitivity and positive involvement with their child. Secondary outcomes included parents' perceptions of their relationship with the child, child‐rearing conflicts and the child's psychosocial health. We found significant effects favouring the intervention arm following the intervention and at follow‐up on two primary outcomes (parental self‐efficacy and emotion sensitivity). For the secondary outcomes, we found a significant reduction in child‐rearing conflict at the 4‐month follow‐up, increased closeness to the child, reduced child internalizing difficulties and increased prosocial behaviour immediately following the intervention. However, ICDP seems to have limited effects on parent‐reported changes in children. We conclude that ICDP as a universal preventive programme offered to parents in groups can be effective in strengthening parental self‐efficacy and improving parental emotion sensitivity.

This study explored the developmental trajectories of postpartum weight from 0.5 to 3 years after childbirth, and aimed to determine the associations between postpartum weight trajectories and prepregnancy body mass index and adequacy of gestational weight gain (GWG). Data from the Norwegian Mother and Child Cohort study were used, following 49,528 mothers 0.5, 1.5, and 3 years after childbirth. Analyses were performed using latent growth mixture modeling. Three groups of developmental trajectories of postpartum weight were found, with most women (85.9 %) having a low level of weight retention initially and slight gain over 3 years, whereas 5.6 % of women started at a high postpartum weight retention (on average 7.56 kg) at 0.5 years but followed by a marked weight loss over time (2.63 kg per year on average), and the third trajectory represented women (8.5 %) who had high weight retention high initially (on average 4.67 kg at 0.5 years) and increasing weight over time (1.43 kg per year on average). Prepregnancy overweight and obesity and excessive GWG significantly predicted a high postpartum weight trend. Women had substantial variability in postpartum weight development-both initially after birth and in their weight trajectories over time. Early preventive interventions may be designed to assist women with prepregnancy overweight and obesity and excessive GWG, which helps to reduce the increasing trend for postpartum weight., Author(s): Dawit S.

Objective: To determine the association between continued antidepressant use in pregnancy and postpartum psychiatric visits for eating (ED) or mood/anxiety disorders in women with preexisting ED. Method: Using Danish health registry data (1998–2015), we identified 3529 pregnancies in women with ED prepregnancy: (i) 564 with continued antidepressant use before and during pregnancy; (ii) 778 with discontinued antidepressants before pregnancy; (iii) 2137 unexposed. Outpatient and inpatient postpartum visits for an ED or a mood/anxiety disorder constituted the outcome measures. We estimated hazard ratios (HRs) and 95% confidence intervals (CI) using Cox regression with inverse probability of treatment weighting, and performed stratified analyses by antidepressant prescription filling in the first 3 months postpartum. Results: The weighted cumulative incidence for an ED visit at end of follow‐up was 4.5% (continued) and 4.8% (discontinued). We found no association between continued antidepressant and postpartum ED visit, relative to discontinued (HR: 0.89, 95% CI: 0.52–1.52). The HR for postpartum mood/anxiety disorder visit was 1.27 (95% CI: 0.68–2.36) with continued antidepressants versus discontinued but decreased if more than two antidepressant prescriptions were refilled. Continued antidepressant use was associated with a 57% reduced likelihood of a postpartum ED visit versus discontinued use in pregnancies with antidepressant prescription refills in the early postpartum. Conclusion: Among women with preexisting ED, there was no association between continued antidepressant use during pregnancy and the likelihood of postpartum psychiatric visits, relative to discontinued antidepressants before pregnancy. Continuation of treatment into the early postpartum is associated with reduced likelihood of postpartum ED visit. Public Significance: Based on data from the Danish registries, we identified 3529 pregnancies among women with preexisting eating disorders before pregnancy. Women with continued antidepressant treatment both before and during pregnancy did not have a lower probability of having postpartum psychiatric visits for an eating disorder or for mood/anxiety disorders (often coexisting with eating disorders), relative to those who discontinued antidepressants before pregnancy. Further continuation of antidepressant treatment into the early postpartum is associated with improved maternal postpartum outcomes. However, residual confounding by disease severity limits confidence in this conclusion. [ABSTRACT FROM AUTHOR]

There is a lack of research on the role that new media play in the life of young children under the age of 13 years. Hence, the aim of the present study was to investigate the relationship between distinct media user types and social displacement among children under the age of 13. A sample of 1,117 Norwegian schoolchildren from the age of 7 to 12 years responded to a questionnaire about their computer game-playing habits and their use of computers, the Internet, mobile phones and television. The results indicate four specific user types reflecting children’s various uses of new media: a) Advanced Users, b) Offline Gamers, c) Instrumental Users, and d) Low Users. Some indications of displacement were found between TV, reading and drawing and between new media usage and participation in organized sports activities. At the same time, clear indications support the “more is more” hypothesis, which predicts that active media users will be active children.

Abstract Background Subclinical forms of eating disorders (ED) are highly prevalent, but relatively little is known about age trends, gender differences and distinctions among symptoms. This study investigates age trends and gender difference in binge eating, purging and non-purging compensatory behaviours (CB) and the relationship of such behaviours to psychosocial problems. Methods Data from the national representative longitudinal study "Young in Norway" (ages 14-34 years) were analysed using χ2 tests, logistic random intercept models and analyses of covariance. Results For both genders, a decrease was found in the prevalence of CB from age 14-16 years to 23 years and over. For binging, however, a significant decrease was found only for females, whose binge eating also declined more markedly over time than did males'. A significant gender difference was detected for purging, with females at higher risk. Purging was related to particularly serious symptoms of psychosocial problems: Those who purged had significantly higher levels of appearance dissatisfaction, anxiety and depressive symptoms, alcohol consumption, self-concept instability and loneliness than those with symptoms of other forms of disordered eating. Conclusions Individuals affected by purging need to be targeted as a high-risk group. The distinction in severity among the subclinical ED may indicate the need for the reformulation of the eating disorder not otherwise specified category in the Diagnostic and Statistical Manual of Mental Disorders-V.

Introduction and Aims: Adolescent drinking has decreased in numerous high‐income countries in the 2000s, and how to explain this downward trend is far from clear. Focussing on the decline in drinking to intoxication among youth in Norway, we examined the following potential explanatory factors: family/home‐based and peer‐oriented leisure‐time activities, perceived parental drinking, drug substitution, school conscientiousness and delinquency. Design and Methods: Data stemmed from cross‐sectional surveys of adolescents aged 13–17 years in the four largest cities in Norway in 2002 (n = 1204) and in 2013/2015 (n = 31 441). We examined the extent to which the decline in intoxication prevalence was attributable to the possible explanatory variables using logistic regression analysis. Results: The proportion reporting any past‐year intoxication episodes dropped markedly from 2002 (41%) to 2013/2015 (22%). Family/home‐oriented leisure‐time activities and school conscientiousness increased, whereas hanging out with friends in the evening and delinquent behaviours decreased. These factors together accounted for 43% of this decline. Decrease in going out with friends was the most important factor. We found no empirical support for assumptions that perceived parental drinking or drug substitution had contributed to the decrease in drinking to intoxication. Discussion and Conclusions: Since the millennium shift, urban adolescents in Norway have become more home‐, family‐ and school‐oriented, and less involved in unsupervised socialising with peers and delinquency. These changes may have contributed to some of the reduction in the prevalence of intoxication in this population group. [ABSTRACT FROM AUTHOR]

Cosmetic breast surgery experience and a wide range of mental health, psychosocial, and sociodemographic variables were assessed in the population-based Norwegian Mother and Child Cohort Study (N = 78,252). Breast augmentation patients reported elevated mental health problems. Factors in the domains of physical appearance, drug use, relationships, and exposure to abuse were all related to breast augmentation. Adjusting for such factors reduced the relationships between breast augmentation surgery and all mental health problems to non-significance. Results indicate that the increased prevalence of mental health problems among breast augmentation patients has to be understood from multiple perspectives involving several psychosocial domains.

Objective: The fetal programming model hypothesizes that developmental programming in utero and in early life induces adaptations that predetermine the adult phenotype. This study investigated whether prenatal/perinatal complications are associated with lifetime eating disorders in women. Method: Participants included 46,373 adult women enrolled in the Norwegian Mother and Child Cohort Study (den norske Mor & barn‐undersøkelsen [MoBa]). MoBa mothers and their mothers (MoBa grandmothers) were the focus of the current study. MoBa mothers with lifetime eating disorders were compared to a referent group. Results: MoBa mothers who weighed more at birth (birth weight, adjusted odds ratio [OR] = 1.14; 95% confidence interval [CI]: 1.10–1.19) or were born large‐for‐gestational‐age (adjusted OR = 1.39; 95% CI: 1.27–1.52) were more likely to develop binge‐eating disorder in later life. MoBa mothers who weighed less at birth were more likely to develop anorexia nervosa (birth weight, adjusted OR = 0.88; 95% CI: 0.81–0.95). Bulimia nervosa and purging disorder (PD) were not significantly predicted by the prenatal and perinatal factors examined. Discussion: Results of this study, which include the first known investigation of prenatal and perinatal factors in binge‐eating disorder and PD, suggest that fetal programming may be relevant to the development of anorexia nervosa and binge‐eating disorder. Future genetically informative research is needed to help disentangle whether these associations are a function of genetic influences or a true environmental fetal programming effect.

Objectives To explore ethnic differences in changes in body mass index (BMI) from the age of 18 years to 3 months postpartum. Design A population-based cohort study. Setting Child Health Clinics in Oslo, Norway. Participants Participants were 811 pregnant women (mean age 30 years). Ethnicity was categorised into six groups. Primary outcome measures The outcome variable was BMI (kg/m2) measured at the age of 18 and 25 years, at prepregnancy and at 3 months postpartum. Body weight at 18 years, 25 years and prepregnancy were self-reported in early pregnancy, while body height and weight at 3 months postpartum were measured. The main statistical method was generalised estimating equations, adjusted for age. The analyses were stratified by parity due to ethnicity×time×parity interaction (p<0.001). Results Primiparous South Asian women had a 1.45 (95% CI 0.39 to 2.52) kg/m2 higher and Middle Eastern women had 1.43 (0.16 to 2.70) kg/m2 higher mean BMI increase from 18 years to postpartum than Western European women. Among multiparous women, the mean BMI increased 1.99 (1.02 to 2.95) kg/m2 more in South Asian women, 1.48 (0.31 to 2.64) kg/m2 more in Middle Eastern women and 2.49 (0.55 to 4.42) kg/m2 more in African women than in Western European women from 18 years to prepregnancy. From 18 years to postpartum, the mean increase was 4.40 (2.38 to 6.42) kg/m2 higher in African women and 1.94 to 2.78 kg/m2 higher in the other groups than in Western European women. Conclusions Multiparous women of ethnic minority origin seem substantially more prone to long-term weight gain than multiparous Western European women in Norway. [ABSTRACT FROM AUTHOR]

Objective: We aim to estimate the pathways between maternal symptoms of anxiety and depression and child nocturnal awakenings via structural equation modeling using a sibling design.Methods: Structural equation modeling on data from 14,926 sibling dyads or triads from the Norwegian Mother and Child Cohort Study.Results: At 6 months, we estimated the association between maternal symptoms of anxiety and child nocturnal awakenings to be owing to several nonsignificant pathways. Child nocturnal awakenings at 18 months, however, were influenced by concurrent maternal symptoms of anxiety (β = .10) and depression (β = .12). Neither maternal symptoms of anxiety (β = .04) nor depression (β = -.00) was influenced by concurrent child nocturnal awakenings.Conclusions: Our findings suggest that maternal mental health influences child sleep behavior at 18 months after birth, and not vice versa. This is in support of hypotheses on maternal mental health influencing child sleep during toddlerhood. [ABSTRACT FROM AUTHOR]

Background: Different methods in pharmacoepidemiology can be used to study hypnotic use in children. But neither questionnaire-based data nor prescription records can be considered a "gold standard". This study aimed to investigate the agreement between mother-reported questionnaire-based data and prescription record data for hypnotic drugs in children aged 0-18 months. The agreement was compared to the agreement for a group of antiepileptic drugs. Methods: Prescription record data were collected from the Norwegian prescription database for 47,413 children also surveyed in the Norwegian mother and child cohort between 2005 and 2009. Agreement between in the two data sources was calculated using Cohens Kappa. Multinomial logistic regression was used to calculate the effect of sociodemographic variables on discrepancies in data sources. Results: The agreement between mother-reported and dispensed hypnotics was less than 50% for all hypnotics. Sensitivity of reporting increased with number of filled prescriptions. The agreement of antiepileptic drugs was 92.9% in the same population. Of several sociodemographic factors only paternal educational level and maternal work situation was significantly related to agreement between prescription record and survey data. Conclusion: There was a moderate agreement between reported use and dispensed hypnotic drugs for infants and toddlers. Results indicate that sociodemographic factors play only a minor role in explaining discrepancy. [ABSTRACT FROM AUTHOR]

Introduction: Little is known about medication use among women with eating disorders in relation to pregnancy. Aims: To explore patterns of and associations between use of psychotropic, gastrointestinal and analgesic medications and eating disorders in the period before, during and after pregnancy. Method: This study is based on the Norwegian Mother and Child Cohort Study (MoBa). A total of 62,019 women, enrolled at approximately 17 weeks' gestation, had valid data from the Norwegian Medical Birth Registry and completed three MoBa questionnaires. The questionnaires provided diagnostic information on broadly defined anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and recurrent self-induced purging in the absence of binge eating (EDNOS-P), along with self-reported use of medication six months before, during, and 0–6 months after pregnancy. Results: The prevalence of eating disorder subtypes before and/or during pregnancy was: 0.09% AN (n = 54), 0.94% BN (n = 585), 0.10% EDNOS-P (n = 61) and 5.00% BED (n = 3104). The highest over-time prevalence of psychotropic use was within the AN (3.7–22.2%) and EDNOS-P (3.3–9.8%) groups. Compared to controls, BN was directly associated with incident use of psychotropics in pregnancy (adjusted RR: 2.25, 99% CI: 1.17–4.32). Having AN (adjusted RR: 5.11, 99% CI: 1.53–17.01) or EDNOS-P (adjusted RR: 6.77, 99% CI: 1.41–32.53) was directly associated with use of anxiolytics/sedatives postpartum. The estimates of use of analgesics (BED) and laxatives (all eating disorders subtypes) were high at all time periods investigated. Conclusions: Use of psychotropic, gastrointestinal, and analgesic medications is extensive among women with eating disorders in the period around pregnancy. Female patients with eating disorders should receive evidence-based counseling about the risk of medication exposure versus the risk of untreated psychiatric illness during pregnancy and postpartum.

This review summarizes studies on eating disorders in pregnancy and the postpartum period that have been conducted as part of the broader Norwegian Mother and Child Cohort Study (MoBa). Prior to the 2000s, empirical literature on eating disorders in pregnancy was sparse and consisted mostly of studies in small clinical samples. MoBa has contributed to a new era of research by making population-based and large-sample research possible. To date, MoBa has led to 19 eating disorder studies on diverse questions including the prevalence, course, and risk correlates of eating disorders during pregnancy and the postpartum. The associations between eating disorder exposure and pregnancy, birth and obstetric outcomes, and maternal and offspring health and well-being, have also been areas of focus. The findings indicate that eating disorders in pregnancy are relatively common and appear to confer health risks to mother and her child related to sleep, birth outcomes, maternal nutrition, and child feeding and eating.

Background This study aimed to examine whether a mismatch between a woman's preferred and actual mode of delivery increases the risk of post-traumatic stress symptoms after childbirth. Methods The study sample consisted of 1,700 women scheduled to give birth between 2009 and 2010 at Akershus University Hospital, Norway. Questionnaire data from pregnancy weeks 17 and 32 and from 8 weeks postpartum were used along with data obtained from hospital birth records. Post-traumatic stress symptoms were measured with the Impact of Event Scale. Based on the women's preferred and actual mode of delivery, four groups were established: Match 1 (no preference for cesarean section, no elective cesarean section, N = 1,493); Match 2 (preference for cesarean section, elective cesarean section, N = 53); Mismatch 1 (no preference for cesarean section, elective cesarean section, N = 42); and Mismatch 2 (preference for cesarean section, no elective cesarean section, N = 112). Analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were conducted to examine whether the level of post-traumatic stress symptoms differed significantly among these four groups. Results Examining differences for all four groups, ANOVA yielded significant overall group differences (F = 11.96, p < 0.001). However, Bonferroni post-hoc tests found significantly higher levels of post-traumatic stress symptoms only in Mismatch 2 compared to Match 1. This difference could be partly explained by a number of risk factors, particularly psychological risk factors such as fear of childbirth, depression, and anxiety. Conclusions The results suggest increased post-traumatic stress symptoms in women who preferred delivery by cesarean section but delivered vaginally compared to women who both preferred vaginal delivery and delivered vaginally. In psychologically vulnerable women, such mismatch may threaten their physical integrity and, in turn, result in post-traumatic stress symptoms. These women, who often fear childbirth, may prefer a cesarean section even though vaginal delivery is usually the best option in the absence of medical indications. To avoid potential trauma, fear of childbirth and maternal requests for a cesarean section should be taken seriously and responded to adequately. [ABSTRACT FROM AUTHOR]

We investigated longitudinal predictors for disordered eating from early adolescence to young adulthood (12–34 years) across gender and different developmental phases among Norwegian young people. Survey data from a population-based sample were collected at four time points (T) over a 13-year time span. A population-based sample of 5,679 females and males at T1 and T2, 2,745 at T3 and 2,718 at T4 were included in analyses, and linear regression and random intercept models were applied. In adolescence, initial disordered eating and parental overprotectiveness were more strongly related to disordered eating among females, whereas loneliness was a stronger predictor for adolescent males. Initial disordered eating during early adolescence predicted later disordered eating more strongly in late- than mid-adolescence. In young adulthood, no significant gender-specific risk factors were found. The findings provide support for both shared and specific risk factors for the developmental psychopathology of disordered eating. [ABSTRACT FROM PUBLISHER]

Fear of childbirth (FOC) is an important women''s health issue. The Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ) is currently the most frequently used instrument to measure FOC. The scale is designed to measure different aspects of FOC but is conceptualized as a uni-dimensional instrument. Our aim was to investigate the underlying factor structure of the W-DEQ version A. A total of 1642 women scheduled to give birth at Akershus University Hospital (Norway) during 2009 and 2010 completed the W-DEQ in the third trimester. Validity and reliability were estimated by means of exploratory and confirmatory factor analyses and correlations with other relevant variables. Results confirmed a multidimensional structure of the W-DEQ. Six factors were identified, each measuring different domains: ''Fear'', ''Negative appraisal'', ''Loneliness'', ''Lack of self-efficacy'', ''Lack of positive anticipation'', and ''Concerns for the child''. The final model resulted in a 25-item version of the instrument with adequate psychometric properties. Subfactors correlated differently with several relevant variables. Especially the factor ''Fear'' was highly correlated with both the overall W-DEQ and several important outcomes. Future studies could examine whether this factor may serve as a good proxy for the full W-DEQ version A. [ABSTRACT FROM AUTHOR]

Objective: To identify factors associated with incidence and course of broadly defined binge eating disorder (BED) in pregnancy. Method: As a part of the Norwegian Mother and Child Cohort Study (MoBa), 45,644 women completed a questionnaire at approximately 18 weeks of gestation. Results: Incidence of BED was significantly associated with lifetime sexual abuse, lifetime physical abuse, lifetime major depression, symptoms of anxiety and depression, low life satisfaction, low self-esteem, low partner relationship satisfaction, smoking, alcohol use, lack of social support, and several weightrelated factors. Continuation was negatively associated with thoughts of being overweight before pregnancy. Remission was positively associated with thoughts of being overweight before pregnancy and negatively associated with overvaluation of weight. Discussion: Onset of BED in pregnancy was associated with psychological, social and weight-related factors, as well as health behaviors and adverse life events. In women with prepregnancy BED, thoughts of being overweight before pregnancy and overvaluation of weight were associated with course of BED during pregnancy. [ABSTRACT FROM AUTHOR]
