Do Children Carry the Weight of Divorce?

Carry that weight: Parental separation and children's Body Mass Index from childhood to young adulthood

Research has shown that parental separation is associated with worse physical health and unhealthy weight gains during childhood. However, limited empirical attention has been given to the evolution of child health before, upon and following parental union dissolution. Drawing on data from the Child Development Supplement and the Transition to Adulthood Supplement of the Panel Study of Income Dynamics (1997-2017), I investigate whether parental union dissolution during childhood is associated with children's Body Mass Index (BMI) and the risk of developing overweight/obesity in the short and long run (n = 2675 children aged 0-12 in 1997). The results from a combination of propensity score matching and fixed-effects linear regression models show that union dissolution is associated with increases in child BMI and an increased risk of developing overweight/obesity. These changes in children's weight status persist for at least ten years after parental separation. Unhealthy weight gains following parental separation are more pronounced among female children and those with lower-educated and non-White parents. The findings suggest that in the United States parental union dissolution contributes to increase socioeconomic inequalities in child health. Therefore, children with separated parents and lower socioeconomic backgrounds have greater risks of developing overweight/obesity and other obesity-related morbidities over their life courses.

Analyzing the Impact of Family Structure Changes on Children's Stress Levels Using a Stress Biomarker

Changes in family structure (e.g., parental separation or stepfamily formation) are associated with a deterioration in children's well-being. Most researchers have focused on the impact of such changes on children's educational and psychosocial outcomes, whereas the effects on children's biological processes have been studied less often. We analyze the effects of changes in family structure on children's stress levels using data from the German Health Interview and Examination Survey for Children and Adolescents study (2003-2006 and 2014-2017). Our outcome variable is the biomarker c-reactive protein (CRP), which correlates with psychological distress and is collected from blood samples. Calculating first-difference estimators, we analyze whether children have higher CRP levels after changing to (1) single-parent families (n = 117) or (2) stepfamilies (n = 80). Our findings suggest that changing to a single-parent family significantly increases children's stress, whereas changing to a stepfamily does not. These observations are important because increased stress in childhood can negatively affect well-being later in life.

Birth and early parenting during the COVID-19 pandemic: A cross-sectional study in the Austrian and German population

BACKGROUND

During the COVID-19 pandemic, new mothers and their babies represent a particularly vulnerable group. This study investigates the effects of the pandemic on the pregnancy and childbirth experience, as well as on postnatal stress and depression levels.

METHODS

An online survey was completed by 1964 Austrian and German mothers who gave birth during the COVID-19 pandemic. The survey included the Pregnancy Distress Questionnaire (PDQ), the Childbirth Experience Questionnaire (CEQ), the Edinburgh Postnatal Depression Score (EPDS), the Perceived Stress Score (PSS), and additional pregnancy- and pandemic-related questions. We conducted multilinear regression models in order to investigate which factors predict childbirth experience, stress and depression scores.

FINDINGS

There was a high prevalence of depression symptoms (42%), though the mean EPDS score was 8·71 (SD = 5·70), below the cut-off for depression of 10. The prevalence of high stress scores was 9%, and the mean PSS score was 17·7 (SD = 6·64), which indicates moderate perceived stress. The pandemic reduced the time spent with grandparents, as well as the help received by the mother from relatives and friends. Not receiving help was associated with higher stress and depression scores. In the multilinear regression models, the most important predictor for a negative childbirth experience was a high-risk pregnancy, while the strongest predictors for high stress and depression levels were low social support and negatively perceived pandemic repercussions on financial, social or health aspects of family life.

INTERPRETATION

The results suggest that the pandemic had an impact on maternal mental health. While the perceived consequences due to the pandemic negatively affected the postnatal depression and stress levels, perceived social support acted as a protective factor.

Health outcomes of only children across the life course: An investigation using Swedish register data

Only children (with no full biological siblings) are a growing subgroup in many high-income settings. Previous studies have largely focused on the short-term developmental outcomes of only children, but there is limited evidence on their health outcomes. Using Swedish population register data for cohorts born 1940-75, we compare the health of only children with that of children from multi-child sibling groups, taking into account birth order, family size, and presence of half-siblings. Only children showed lower height and fitness scores, were more likely to be overweight/obese in late adolescence, and experienced higher later-life mortality than those with one or two siblings. However, only children without half-siblings were consistently healthier than those with half-siblings, suggesting that parental disruption confers additional disadvantages. The health disadvantage was attenuated but not fully explained by adjustment for parental characteristics and after using within-family maternal cousin comparison designs.

Association between lifestyle-related, psychosocial factors and obesity among female adolescents in Taiwan

PURPOSE

To examine a wide range of potential contributors to the risk of obesity in female adolescents.

DESIGN AND METHODS

Data for this study were collected using a cross-sectional design. A group of 175 female adolescents were recruited, and information on their demographic characteristics, lifestyle-related behaviors, and psychosocial factors was collected using a self-administered questionnaire during September 2018 to January 2019. Data were analyzed using SPSS 24.0.

RESULTS

An overestimation of body weight was negatively correlated with overweight in the female adolescents. Age at menarche was negatively correlated with the arisk of overweight. Adolescents who slept for >7 h on weekend nights were less likely to be overweight. Eating more cheese, fish, seafood, and organ meats was negatively correlated with obesity risk. The female adolescents were more likely to become overweight if they ate dinners prepared by family and experienced more disturbances from parents and other family members.

CONCLUSIONS

Female adolescents are a unique population affected by obesity. Although incorporating both lifestyle-related behavioral and psychosocial factors in future investigations and developing multicomponent interventions for obesity prevention are crucial, female adolescents should receive the utmost attention from researchers to alleviate the health burden of obesity.

PRACTICE IMPLICATIONS

The intertwined nature of obesity-related factors warrants future investigations to elaborate their roles interplaying with the risk of obesity. Multicomponent interventions should be developed, and nurses and health-care providers should target their efforts on obesity prevention for this specific population.

Adverse childhood experiences and pre-pregnancy body mass index in the HUNT study: A population-based cohort study

OBJECTIVE

Investigate the association between adverse childhood experiences and pre-pregnancy body mass index (BMI) in a population-based cohort in Trøndelag county, Norway.

MATERIALS AND METHODS

We linked data from the third (2006-2008) or fourth (2017-2019) survey of the Trøndelag Health Study (HUNT) and the Medical Birth Registry of Norway for 6679 women. Multiple logistic regression models were used to examine the association between adverse childhood experiences and pre-pregnancy BMI. Adverse childhood experiences were self-reported in adulthood and included perceiving childhood as difficult, parental divorce, parental death, dysfunctional family environment, bad childhood memories and lack of support from a trusted adult. Pre-pregnancy BMI was derived from the Medical Birth Registry of Norway or BMI measurement from the HUNT survey conducted within 2 years prior to the woman's pregnancy.

RESULTS

Perceiving childhood as difficult was associated with higher odds of pre-pregnancy underweight (OR 1.78, 95%CI 0.99-3.22) and obesity (OR 1.58, 95%CI 1.14-2.2). A difficult childhood was positively associated with obesity with an adjusted OR of 1.19, 95%CI 0.79-1.81 (class I obesity), 2.32, 95%CI 1.35-4.01 (class II obesity) and 4.62, 95%CI 2.0-10.65 (class III obesity). Parental divorce was positively associated obesity (OR 1.34, 95%CI 1.10-1.63). Bad childhood memories were associated with both overweight (OR 1.34, 95%CI 1.01-1.79) and obesity (OR 1.63, 95%CI 1.13-2.34). Parental death was not associated with pre-pregnancy BMI.

CONCLUSIONS

Childhood adversities were associated with pre-pregnancy BMI. Our results suggest that the positive associations between childhood adversities and pre-pregnancy obesity increased with increasing obesity level.

Exploring the associations between number of children, multi-partner fertility and risk of obesity at midlife: Findings from the 1970 British Cohort Study (BCS70)

BACKGROUND

Early parenthood, high parity, and partnership separation are associated with obesity. However, the emergence of non-marital partnerships, serial partnering and childbearing across unions, means that it is important to consider their association to obesity. This paper examined the associations between number of biological children and multi-partner fertility (MPF)-defined as having biological children with more than one partner, with obesity at midlife.

METHOD

The sample consisted of 2940 fathers and 3369 mothers in the 1970 British Cohort Study. The outcome was obesity (BMI 30 or over) at age 46. Fertility and partnership histories ascertained the number of live biological children and MPF status by age 42. The associations were tested using logistic regression adjusting for confounders at birth, age 10 and age 16. Adult factors recorded at age 42 including age at first birth, smoking status, alcohol dependency, educational attainment and housing tenure were considered as mediators.

RESULTS

For fathers, obesity odds did not differ according to number of children or MPF. In unadjusted models, mothers with one child (OR 1.24 95%CI 1.01-1.51), mothers who had two children with two partners (OR 1.45 95%CI 1.05-1.99), and mothers who had three or more children with two or more partners (OR 1.51 95%CI 1.18-1.93) had higher odds of obesity. In adjusted models, there remained an association between mothers with one child and odds of obesity (OR 1.30 95%CI 1.05-1.60). All other associations were attenuated when confounders were included.

CONCLUSIONS

Mothers who had children with multiple partners had higher odds of obesity. However this association was completely attenuated when parental and child confounders were accounted for; suggesting that this association may be explained by confounding. Mothers who had one child only may be at increased odds of obesity, however this could be due to multiple factors including age at first birth.

Early-life exposure to economic stress and metabolic risks in young adulthood: the children of the reunification in East Germany

BACKGROUND

Research on the long-term health consequences of early-life exposure to economic crises is scarce. We examine for the first time the long-term effects of early-life exposure to an economic crisis on metabolic health risks. We study objective health measures, and exploit the quasi-experimental situation of the postreunification economic crisis in East Germany.

METHODS

Data were drawn from two waves of the longitudinal German Health Interview and Examination Survey for Children and Adolescents (2003-2006, 2014-2017). We compared 392 East Germans who were exposed to the economic crisis in utero and at ages 0-5 with 1123 of their West German counterparts using propensity score matching on individual and family characteristics. We assessed blood pressure, cholesterol, blood fat and body mass index (BMI); both combined as above-average metabolic health risks and individually at ages 19-30.

RESULTS

Early-life exposure to the economic crisis significantly increased the number of above-average metabolic health risks in young adulthood by 0.1482 (95% CI 0.0169 to 0.2796), which was 5.8% higher compared with no exposure. Among individuals exposed in utero, only females showed significant effects. Early-life exposure to the economic crisis was associated with increased systolic (0.9969, 95% CI -0.2806 to 2.2743) and diastolic blood pressure (0.6786, 95% CI -0.0802 to 1.4373), and with increased BMI (0.0245, 95% CI -0.6516 to 0.7001).

CONCLUSION

The increased metabolic health risks found for women exposed to the postreunification economic crisis in-utero are likely attributable to increased economic stress. While the observed differences are small, they may foreshadow the emergence of greater health disparities in older age.

Parental Traits Associated with Adherence to the Mediterranean Diet in Children and Adolescents in Croatia: A Cross-Sectional Study

The Mediterranean diet (MD) is known to be one of the healthiest dietary patterns. Despite the significance of a healthful diet during the early stage of life, data for young individuals indicate that nutrition problems are common. This cross-sectional study aimed to determine parental factors associated with MD adherence in children and adolescents living in the Mediterranean region in Croatia. In total, 2623 children aged 2 to 18 years and their parents participated in this study. Data were collected during the period from September 2021 to February 2022 by using an anonymous questionnaire. We used KIDMED and MEDAS questionnaires for assessing MD adherence in young individuals and their parents, respectively. To assess the association of children’s MD adherence categories with the parental predictors, we performed multivariate multinomial logistic regression. Results showed that the children of parents with a low MD adherence are much more likely to have poor MD adherence than good (OR = 47.54 (95% C.I 18.24, 123.87), p < 0.001) or average (OR = 5.64 (95% C.I 3.70, 8.6), p < 0.001) MD adherence. Further, children of fathers with higher BMI (OR = 1.035 (95% C.I 1.0, 1.071)) and those who do not live with both parents (OR = 1.703 (95% C.I 0.994, 2.916), p = 0.053) are more likely to have poor MD adherence than good MD adherence. These results indicate that interventions focusing on enhancing the quality of both parents’ diets could effectively improve their children’s eating habits.

The mediating pathways between parental separation in childhood and offspring hypertension at midlife

Social life course determinants of adult hypertension are relatively unknown. This paper examines how parental separation before age 10 relates to hypertension at age 46. Adjusting for parental confounders and considering the role of adult mediators, we aim to quantify unexplored mediating pathways in childhood using prospectively collected data. Data from the 1970 British Birth Cohort Study are utilised. Hypertension is measured by health care professionals at age 46. Potential mediating pathways in childhood include body mass index (BMI), systolic and diastolic blood pressure, illness, disability, family socioeconomic status (SES) and cognitive and developmental indicators at age 10. Additionally, we explore to what extent childhood mediators operate through adult mediators, including health behaviours, family SES, BMI and mental wellbeing. We also test for effect modification of the relationship between parental separation and hypertension by gender. Nested logistic regression models test the significance of potential mediating variables. Formal mediation analysis utilising Karlson Holm and Breen (KHB) method quantify the direct and indirect effect of parental separation on offspring hypertension at midlife. There was an association between parental separation and hypertension in mid-life in women but not men. For women, family SES and cognitive and behavioural development indicators at age 10 partly mediate the relationship between parental separation and hypertension at age 46. When adult mediators including, health behaviours, family SES, BMI and mental wellbeing are included, the associations between the childhood predictors and adult hypertension are attenuated, suggesting that these childhood mediators in turn may work through adult mediators to affect the risk of hypertension in midlife. We found family SES in childhood, cognitive and behaviour development indicators at age 10, including disruptive behaviour, coordination and locus of control in childhood, to be important mediators of the relationship between parental separation and midlife hypertension suggesting that intervening in childhood may modify adult hypertension risk.

Fair comparisons: Life course selection bias and the effect of father absence on US children

Studies have shown that father absence in opposite-gender couples has detrimental effects on children's wellbeing, net of selection bias. However, life course informed research suggests that the problem of selection bias may be more complex than currently thought. This paper shows the importance of nonparametrically adjusting for the trajectory of confounder covariates for the estimation of these effects. This paper uses data from the Fragile Families and Child Wellbeing Study to estimate the total effect of the departure of the biological father on children's wellbeing, as well as delayed or fade-out effects of this transition. The paper employs Bayesian additive regression trees, a machine learning and causal inference method suited for statistical models involving high-dimensional data sets. After adjusting for multiple time-invariant and -varying confounder covariates, as well as their history, estimates of father absence's effect on children's wellbeing are reduced substantially, a finding which may be referred to as life course selection bias. Results suggest early and middle childhood are not negatively affected by the departure of the biological father. Life course selection bias mostly affects estimates of this effect on adolescence, which is explained by children directly experiencing changes inparent's socioeconomic trajectories that lead to divorce or separation. This would not be the case when father absence is experienced in early childhood. Results suggest father absence is mostly a marker of life course cumulative socioeconomic disadvantage, not a cause of negative effects.

Early childhood family background predicts meal frequency behaviour in children: Five-year follow-up study

AIMS

Childhood nutrition patterns have an important role in later health. We studied the role of family type, other family background factors and their changes over a five-year follow-up with respect to meal frequency among children.

METHODS

Longitudinal data were collected in 2007-2009 and 2013-2014. A nationally representative sample of Finnish children (n = 1822) aged 0.5-5 years at baseline and 5-10 years at follow-up and their families were used. The participation rate was 83% at baseline and 54% at follow-up. Meal frequency was defined as four to six meals per day. The associations of meal frequency with family background factors over a five-year follow-up period were examined by bivariate and multivariate regression analyses.

RESULTS

Eighty-nine per cent of the 5-10-year-old boys and girls had the recommended meal frequency at follow-up. Living in a single-parent family at baseline increased the risk of not eating the recommended number of meals compared with those living in intact families. After adjustments, a mother's low level of education (OR 0.51, CI 0.29-0.93) and a decrease in income sufficiency (OR 0.54, CI 0.35-0.84) during the follow-up period were unfavourably associated with the recommended meal frequency. The difference between children in stable single-parent, reconstituted or joint physical custody families and those living in stable intact families remained significant when controlling for other variables.

CONCLUSIONS

Single-parent families with a low socioeconomic position represent important target groups for interventions designed to promote regular meal frequency.

A genetic basis for friendship? Homophily for membrane-associated PDE11A-cAMP-CREB signaling in CA1 of hippocampus dictates mutual social preference in male and female mice

Although the physical and mental benefits of friendships are clear, the neurobiological mechanisms driving mutual social preferences are not well understood. Studies in humans suggest friends are more genetically similar, particularly for targets within the 3',5'-cyclic adenosine monophosphate (cAMP) cascade. Unfortunately, human studies can not provide conclusive evidence for such a biological driver of friendship given that other genetically related factors tend to co-segregate with friendship (e.g., geographical proximity). As such, here we use mice under controlled conditions to test the hypothesis that homophily in the cAMP-degrading enzyme phosphodiesterase 11A4 (PDE11A4) can dictate mutual social preference. Using C57BL/6J and BALB/cJ mice in two different behavioral assays, we showed that mice with two intact alleles of Pde11a prefer to interact with Pde11 wild-type (WT) mice of the same genetic background over knockout (KO) mice or novel objects; whereas, Pde11 KO mice prefer to interact with Pde11 KO mice over WT mice or novel objects. This mutual social preference was seen in both adult and adolescent mice, and social preference could be eliminated or artificially elicited by strengthening or weakening PDE11A homodimerization, respectively. Stereotactic delivery of an isolated PDE11A GAF-B domain to the mouse hippocampus revealed the membrane-associated pool of PDE11A-cAMP-CREB signaling specifically within the CA1 subfield of hippocampus is most critical for regulating social preference. Our study here not only identifies PDE11A homophily as a key driver of mutual social preference across the lifespan, it offers a paradigm in which other mechanisms can be identified in a controlled fashion.

Eater profile and associated factors in pediatric patients of the PEDIANUT cohort

Appetite traits have multifactorial origins. In association with environmental and genetic factors, they could become problematic and lead to Feeding or Eating Disorders (FED). As the DSM-5 classification is not suitable for pediatric FED, another way to describe eating behavior is to distinguish the clinical profiles of "small eater" and "big eater". The aim of this study was to identify socio-demographic and medical factors associated with these profiles, and to compare problematic and non-problematic profiles. From the Pedianut study, we analyzed socio-demographic, medical and family history data among 401 children according to 4 age groups (<1 year n = 101, 1-6 years n = 99, 6-12 years n = 100, 12-18 years n = 101). The information collected on eating behavior made it possible to define small eater profile (SEP) and big eater profile (BEP) using predefined grids. BEP was more frequent in adolescents (35.6%), and SEP was more frequent in children aged 1-6 years (34.3%). BEP was associated with having separated parents, being male and the oldest sibling (p < 0.05). Problematic BEP was associated with eating while watching television, being a girl, and having sensory disorders (p < 0.05). SEP was associated, whatever age, with non-breastfeeding, chronic illness, psychological history, sensory disorders, language delays (in the 1-6 year age group), and family history of FED (in the adolescent group) (p < 0.05). This analysis of factors associated with eater profile opens new perspectives for research on risk factors associated with eating traits, which warrants further study in larger populations to delineate transition from healthy to problematic eating.

Mental Health Around the Transition to First Birth: Does Medically Assisted Reproduction Matter?

Previous research has shown that childbearing is associated with short-term improvements in women's subjective well-being but that these effects depend on the timing and quantum of the birth as well as on the parents' education and socioeconomic status. These studies did not address whether and, if so, how this effect varies according to the mode of conception. This represents an important knowledge gap, given that conceptions through medically assisted reproduction (MAR) have been increasing rapidly in recent decades, exceeding 5% of live births in some European countries. Drawing on nine waves (2009/2010-2017/2018) of the UK Household Longitudinal Study, we use distributed fixed-effects linear regression models to examine changes in women's mental health before, during, and after natural and MAR conceptions. The results show that the mental health of women who conceived naturally improved around the time of conception and then gradually returned to baseline levels; comparatively, the mental health of women who conceived through MAR declined in the year before pregnancy and then gradually recovered. The findings also indicate that women's happiness decreased both two years and one year before an MAR conception and then increased above the baseline in the year of pregnancy. We further show that the deterioration in mental health and subjective well-being before an MAR conception affects both partners, which could be part of a longer process in which the partners potentially suffer from stress related not solely to the MAR treatments themselves but also to the experience of subfertility.

Obesity in children and adolescents: An overview

Childhood obesity is an epidemic in the US. This article discusses the evolution, prevention, and associated physical and psychosocial consequences of and interventions for obesity in the pediatric population.

Food addiction: A key factor contributing to obesity?

Background:

People may develop addiction to hyperpalatable foods, which may be a cause of obesity. This study aimed to determine the prevalence of obesity among adolescents and the effect of food addiction on obesity.

Materials and Methods:

In this cross-sectional study, food addiction and obesity status of high school students were investigated. Among 17,000 10^th and 11^th grade students, assuming the design effect as 2.0, with obesity prevalence of 10%, with 3% error, and 95% confidence interval, at least 752 participants were included. Obesity was the dependent variable, whereas sociodemographic characteristics, body image, eating habits, and food addiction were the independent variables. Food addiction was assessed using the Yale Food Addiction Scale. Obesity was determined by age- and sex-specific body mass index (BMI) percentiles for adolescents < 18 years of age and BMI ≥ 30.0 for those aged ≥ 18. Data were collected through face-to-face interviews. Statistical analyses were performed using SPSS 25.0. After adjustment for age, sex, and other variables, the effect of food addiction on obesity was determined through logistic regression. P <0.05 was deemed statistically significant.

Results:

Among adolescents (n = 874), 18.9% were food addict, 25.1% were overweight, and 12.1% were obese. After adjusted for age, sex, and other variables, food addiction significantly increased the risk of obesity (odds ratio: 1.9; 95% confidence interval: 1.167–3.335). Having a fragmented family, working mother, overweight father, and participants not knowing their weight correctly significantly increased obesity.

Conclusion:

While quarter of the adolescents had weight problems, one-fifth suffered from food addiction. After adjusting for confounders, food addiction significantly increased obesity. Identifying individuals with food addiction, providing treatment to overcome that, paying special attention to adolescents with obese parents or living in fragmented families, and providing support to both parents and adolescents could be useful in tackling obesity.

Mediterranean Diet Adherence among Preschoolers and its Association with Parents' Beliefs, Attitudes, and Practices

The effect of parents on nutritional habits in preschool children is undeniable. It is known that parental control in child nutrition can affect the child's eating habits, and bodyweight. Mediterranean Diet (MD) adherence of children (KIDMED), parents' beliefs, attitudes and practices (Preschool Feeding Questionnaire-PFQ2) were investigated. The questionnaire prepared was applied by researchers face-to-face to 1413 families who agreed to participate voluntarily in the research with preschool children. Parental beliefs, attitudes, and practices regarding child nutrition status of parents were evaluated using 39-item PFQ2 and their child's eating habits using the 16-item KIDMED index. Children's KIDMED scores were found optimal in 34.1%, average in 57.0%, very low in 8.9%. The KIDMED scores of children whose parents are together (6.6 ± 2.1) were found to be significantly higher than children whose parents are separated (4.9 ± 2.2) (p <.001). A correlation was found between the KIDMED scores of the children, the parental control (r = 0.156, p <.001), maternal restriction (r = 0.104, p <.001), and structured feeding (r = 0.162, p <.001). Unfortunately, the adherence of most preschool children with the MD which considered a healthy diet pattern was found below the optimal level.
