The influence of psychological distress during pregnancy on early postpartum weight retention

The relationship between social determinants of health and postpartum weight retention based on the World Health Organization model: path analysis

BACKGROUND

Postpartum weight retention (PPWR) causes obesity, chronic diseases, and occurring adverse maternal-fetal and neonatal outcomes. Given the social factors' effect on health and disease and considering the lack of information on social determinants of health (SDH) effects on PPWR, this study was conducted to survey the relationship between SDH and PPWR based on the World Health Organization (WHO) model.

METHODS

A cross-sectional study was performed on 400 women six months after delivery in 2020. Twelve health centers were randomly selected from the three universities of Medical Sciences in the city of Tehran, Iran. Participants were selected by convenience method and based on eligibility. Questionnaires used included: Lifestyle Profile Health Promoting II, Short Form Postpartum Quality of Life Questionnaire, Multidimensional Scale of Perceived Social Support, Postpartum Social Support, Depression Anxiety Stress Scales, and questionnaires designed by reviewing the literature about breastfeeding, sleep, contraceptive, child health, unhealthy behaviors, postpartum nutritional awareness/beliefs, body satisfaction, access to postpartum care, socioeconomic status, demographic, and obstetric questionnaire. Data analysis was performed in SPSS-23, and the relationship model was examined using the path analysis method in LISREL-8.8.

RESULTS

Path analysis indicated the direct effect of six intermediate factors on PPWR including: gestational weight gain (β = 0.42), access to postpartum care (β = 0.11), postpartum nutritional awareness/beliefs (β=-0.17), anxiety (β = 0.09), sleep duration (β=-0.09), pre-pregnancy body mass index (β = 0.09). Among the structural factors, woman's education and socioeconomic status had an indirect negative effect on PPWR. The model fit indices showed good fit (RMSE = 0/05, GFI = 0.92, CFI = 0.92, χ²/df = 2.17).

CONCLUSION

The results indicate the effect of structural and intermediate determinants of health on PPWR. It is recommended to use the proposed model as an appropriate framework in the research, design, and implementation of programs to prevent and control PPWR.

'I wish I had my pre-pregnancy body after birth… but I have to be supported': a theoretical study based on body image perception in working mothers during the postpartum period

The body image of women in the postpartum period can be far from society's idealised body, and this can cause body dissatisfaction. This qualitative study aimed to evaluate the body image perception of women who had started working in the postpartum period, based on the grounded theory research method. A total of 22 face-to-face interviews were conducted with participants who were actively involved in working life and between 3 months and 1 year postpartum. The data were collected through in-depth interviews with a personal information form and semi-structured interview form. Coding created four main categories ('weight fluctuations and body shape', 'body-related perception', 'body-related responses from the environment' and 'body perception improvement process') and eight sub-categories. The results found that the postpartum period is a sensitive one for working women, where they have both positive and negative experiences. Their responsibilities increase, they have little time for themselves and their bodies, they experience body image dissatisfaction, and they expect support from their spouses, families, social circles and health professionals.Impact StatementWhat is already known on this subject? Postpartum body image is an important research subject because it expands the scope of body image literature and has significant effects on gender problems. Not being able to lose the weight gained in postpartum period or the weight gained during pregnancy is an important problem for women. With women starting working life, this period seems to be a more sensitive and anxious one for some women.What do the results of this study add? Most of the women in this study experience body dissatisfaction in the postpartum period. Some women do not want to leave the house because of their negative body image perceptions. It is an important finding that women want their spouse to gain weight during this period.What are the implications of these findings for clinical practice and/or further research? The findings of our study revealed that working mothers in the postpartum period have difficulty in sparing time for themselves and their bodies due to increased responsibilities. Working women are in particular need for more support due to their increased workloads, roles and responsibilities in childcare. Our study may guide future studies focussing on women's body image perceptions and influencing factors.

Israeli and British women's wellbeing and eating behaviours in pregnancy and postpartum

OBJECTIVES

The study had two main objectives: (a) track changes in self-esteem, eating behaviours and body satisfaction from early pregnancy to 24 months postpartum and (b) to compare changes by context (Israel vs. UK) and maternal body mass index (BMI).

BACKGROUND

High maternal BMI is associated with negative body image and restrained eating, which are experienced differently across cultures.

METHODS

156 pregnant women were recruited from Israel and the UK. Seventy-three women were followed up every six months from early postpartum and until 24 months following birth. Women completed questionnaires assessing self-esteem (RSEQ), body image (BIS/BIDQ) and eating behaviours (DEBQ) and self-reported weights and heights so that BMI could be calculated.

RESULTS

Women with higher BMI had higher levels of self-esteem and were less satisfied with their body. Healthy-weight women were more likely to lose all of their retained pregnancy weight compared to overweight and obese women. Self-esteem, body image and eating behaviours remained stable from pregnancy until 24 months postpartum. No significant differences were found for any measure by context.

CONCLUSION

BMI was the strongest predictor of self-esteem and body dissatisfaction and a higher BMI predicted less weight loss postpartum.

The weight of fatherhood: identifying mechanisms to explain paternal perinatal weight gain

Men appear to gain weight during the transition to parenthood, and fathers are heavier than non-fathers. Paternal perinatal weight gain may set weight trajectories in midlife and have long-term health implications. Since men do not undergo the physical demands of pregnancy and breastfeeding, the specific mechanisms underlying weight gain in new fathers warrant investigation. This review aims to stimulate research on paternal perinatal weight gain by suggesting testable potential mechanisms that (1) show change across the transition to parenthood and (2) play a role in weight and body composition. We identify seven mechanisms, within three categories: behavioural mechanisms (sleep, physical activity, and diet), hormonal mechanisms (testosterone and cortisol), and psychological mechanisms (depression and stress). We also discuss direct effects of partner pregnancy influences (e.g., 'couvade syndrome') on men's body weight. In presenting each mechanism, we discuss how it may be affected by the transition to parenthood, and then review its role in body composition and weight. Next, we describe bidirectional and interactive effects, discuss timing, and present three broad research questions to propel theoretical development.

The influence of psychological factors on postpartum weight retention 12 months post-birth

Background During the first postpartum year 20% of women retain excessive weight from pregnancy (postpartum weight retention; PPWR), which predicts long-term overweight/obesity. Objective The aim of this study was to explore the associations between psychological factors (depression, anxiety and stress symptoms and body attitudes) in late gestation and at 12-months postpartum with PPWR one-year post-birth. Methods Pregnant women (N = 176) completed questionnaires in early-mid pregnancy (Time 1; mean (SD) = 16.97 (1.35) weeks), late pregnancy (Time 2; mean (SD) = 33.33 (2.05) weeks), and one year postpartum (Time 3; mean (SD) = 53.12 (3.34) weeks). Women provided demographic characteristics, height and pre-pregnancy weight at Time 1. At Times 2 and 3, weight, depressive, anxiety and stress symptoms and body attitudes (salience of weight and shape, attractiveness, feeling fat, and strength and fitness) were assessed in addition to physiological, socio-contextual and lifestyle factors. Gestational weight gain and PPWR were calculated. Hierarchical linear regression models were conducted to explore variance in 12-month PPWR. Results Overall, models explained 26-39% variance in PPWR. Gestational weight gain in late pregnancy and low attractiveness at 12 months postpartum were the only variables associated significantly with 12-month PPWR. Conclusion While psychological factors did not appear to be important direct contributors to PPWR at 12 months, the overall contribution of all variables suggests that such factors may be implicated in a small and incremental way. Exploration of the interactions between variables will help unpack potential mechanisms of the development of PPWR at 12 months post-birth.

The Relationship between Stress and Severe Obesity: A Case-Control Study

Background

Several etiological factors for obesity have been identified, whereas other factors related to obesity, such as stress, remain poorly understood. This study used psychiatric methods to examine the relationship between stress and obesity.

Methods

Matched study and control groups were established, and the female and male control subjects were selected separately by random sampling. The control subjects were matched with the case subjects with respect to place of residence, sex, age, date that a pension was granted, and occupation. Psychiatric and psychological methods were assessed using a questionnaire and statistical analyses.

Results

Psychiatric interviews indicated that stress was more prevalent in the study group than in the control group. Separation from parents was nearly significantly more frequently in the study group than in the control group. The questionnaire on coping mechanisms revealed that case subjects tended to resolve their problems in an active manner.

Conclusions

The aim of this case-control study was to examine the relationship between stress and obesity in individuals receiving a disability pension. We identified stress factors that affect the development of obesity. We believe our study is both necessary and important, as these findings provide valuable insight into the relationship between severe obesity and stress.

Childhood maltreatment and pre-pregnancy obesity: a comparison of obese, overweight, and normal weight pregnant women

Pre-pregnancy overweight and obesity is associated with poor health outcomes for the mother and the child. General population studies suggest that childhood maltreatment is associated with obesity in adulthood. The aim of our study was to examine the association between pre-pregnancy overweight and obesity and a history of childhood abuse or neglect including different stages of severity of abuse and neglect. Three hundred twenty-six normal weight, overweight, or obese pregnant women reported demographic data, height and weight, and general psychological distress at 18-22 weeks of gestation. Childhood maltreatment was assessed using the Childhood Trauma Questionnaire. Associations were examined using logistic regression analyses and a reference group of normal weight women. Fifty percent reported a history of abuse or neglect. After adjusting for age, education, income, marital status, and the number of previous children, pre-pregnancy overweight and obesity were strongly associated with severe physical abuse (overweight: OR = 8.33, 95% CI 1.48-47.03; obesity: OR = 6.31, 95% CI 1.06-37.60). Women with severe physical neglect (OR = 4.25, 95% CI 1.23-14.74) were at increased risk of pregnancy overweight. We found a dose-response relationship between physical abuse and pre-pregnancy overweight and obesity. Whereas other studies report an association between childhood maltreatment and pre-pregnancy obesity, this is the first study that found an association between childhood maltreatment and pre-pregnancy overweight. Considering the severe health risks of pre-pregnancy overweight and obesity and the long-term consequences of childhood maltreatment, affected women constitute a subgroup with special needs in prenatal care. Further research is needed to improve the understanding of the underlying mechanisms.

Obesity and anxiety during pregnancy and postpartum: A systematic review

BACKGROUND

Obesity and anxiety during the perinatal period are common and associated with poor health outcomes for the mother and the child. Despite the well-documented health risks of both pregnancy obesity and anxiety, associations between the two have rarely been explored. With this review we aim to provide a systematic overview of the current state of evidence concerning associations between ante- and postnatal anxiety and pregnancy obesity, excessive gestational weight gain, and postpartum weight retention.

METHODS

We conducted a systematic literature search in PubMed, Web of Science, and PsychINFO.

RESULTS

13 Records matched our inclusion criteria. Five out of seven studies focusing on pregnancy obesity and anxiety suggest a positive association with ante- or postnatal anxiety. Surprisingly, no study examined anxiety disorders according to DSM and it remains unknown whether anxiety symptomatology reaches clinical relevance. Results from a small number of life-style intervention studies (n=3) suggest that interventions could benefit from a stronger focus on mental health. There were not enough studies on associations between excessive gestational weight gain (n=2) or postpartum weight retention (n=3) and anxiety making it difficult to draw conclusions about possible associations.

LIMITATION

The number of included studies is rather small and studies were included irrespective of the study quality which might limit the generalizability of the results.

CONCLUSIONS

The majority of the included studies suggest that obese pregnant women might constitute a subgroup that is especially vulnerable for comorbid anxiety and in need of targeted psychological support. However, further high-quality studies, particularly including anxiety disorders, are needed.
