Pregnancy loss of control over eating: a longitudinal study of maternal and child outcomes

Effectiveness of nutritional counseling with overweight pregnant women on child growth at 6 months: A randomized controlled trial

OBJECTIVE

Studies that have investigated the effect of nutritional counseling during the prenatal period on the follow-up outcomes of children at 6 mo have produced inconclusive results. The present study aimed to investigate the effect of nutritional counseling, based on the NOVA food classification, encouraging the consumption of fresh and minimally processed foods, with overweight adult pregnant women on infant growth at 6 mo of age.

METHODS

A randomized controlled trial with 195 pairs of pregnant overweight women and their infants at 6 mo of age was conducted in a Brazilian municipality. The pregnant women were allocated to the control group (CG) or intervention group (IG) at the beginning of the pregnancy. The IG received three sessions of nutrition counseling throughout the pregnancy. Linear regression models were used to investigate the effect of the nutritional counseling on infant growth.

RESULTS

One hundred ninety-five mother-infant pairs with complete data were included (96 CG, and 99 IG). The mean ± SD infant weight (g) at 6 mo was 7856.1 ± 1.1, and length (cm) was 67.0 ± 2.9. There were no differences in maternal and newborn characteristics between the groups. In the linear regression models, the counseling had no effect on anthropometric parameters of the infants at 6 mo of age: weight-for-length Z-score (β 0.089 [95% CI -0.250; 0.427], P = 0.61); length-for-age Z-score (β 0.032 [95% CI -0.299; 0.363], P = 0.85); weight-for-age Z-score (β 0.070 [95% CI -0.260; 0.400], P = 0.68); BMI-age Z-score (β 0.072 [95% CI -0.270; 0.414], P = 0.68).

CONCLUSIONS

There was no effect on infant growth at 6 mo of age after the nutritional counseling during pregnancy. Future studies are needed to confirm this hypothesis.

Validation of the Weight-Related Eating Questionnaire in pregnancy

The Weight-Related Eating Questionnaire (WREQ), designed for assessing distinct constructs of dietary restraint and disinhibition-related eating behaviors, has not been validated in pregnancy. This secondary data analysis aimed to evaluate the WREQ's psychometrics in a diverse sample of pregnant women from the eMoms randomized controlled trial (N = 1399), randomly split for exploratory (EFA, n = 691) and confirmatory factor analysis (CFA, n = 708). Cronbach's alpha and corrected item-total correlation was used to examine internal consistency reliability. Sequential multiple regression analyses were used to assess criterion validity. EFA revealed three factors - dietary restraint, susceptibility to external cues, and emotional eating - accounting for 65.6 % of total variances. Parallel analysis confirmed a combination of two restraint subtypes (routine restraint and compensatory restraint). CFA showed that item 3 for assessing routine restraint had the lowest squared multiple correlation (0.22). The overall Cronbach's alpha of 0.87 demonstrated good internal consistency. Dietary restraint was negatively associated with the intake of energy (p = .03) and carbohydrates (p = .02), whereas susceptibility to external cues was positively associated with the intake of energy (p < .001), carbohydrates (p < .001), and total fat (p = .003). Additionally, emotional eating was positively associated with early-pregnancy body mass index (BMI) after adjustment for covariates (p < .001). These findings confirmed the reliability of the WREQ, the construct validity for susceptibility to external cues and emotional eating, and demonstrated its criterion validity regarding nutritional intake in pregnant women.

The association between preconception loss of control over eating and depressive symptom trajectories from childhood through first pregnancy

OBJECTIVE

Loss of control over eating (LOC) during pregnancy impacts prenatal health and often co-occurs with depressive symptoms. However, the role of depression history as a risk factor for LOC prior to pregnancy is unclear; information that is essential for effective prenatal health promotion. We examined the association between trajectories of depressive symptoms from childhood to first pregnancy and preconception LOC.

METHOD

Participants (N = 1031) were predominantly Black, first-time mothers enrolled in the population-based Pittsburgh Girls Study. LOC and depressive symptoms were measured annually. Pre-pregnancy height and weight, and gestational weight gain data were abstracted from medical records.

RESULTS

There was a significant difference in age of first conception for Black and White individuals (t = 8.73, df = 976, p < .001). Latent class analysis revealed four and three classes of depressive symptom trajectories for Black and White individuals, respectively. In the entire sample, the high-changing and moderate-decreasing classes of depressive symptoms were each associated with lifetime, in preconception year and not in preconception year, LOC (X2  = 56.7, p < .001).

DISCUSSION

High levels of lifetime depressive symptoms may increase vulnerability to future LOC prior to first pregnancy, suggesting potential targets for interventions to improve maternal health.

PUBLIC SIGNIFICANCE

Both depression history and disordered eating behaviors are known to influence prenatal health. The present study revealed associations between high levels of depressive symptoms from childhood through first pregnancy and loss of control over eating that included the year prior to conception. Results highlight potential targets for preconception interventions with relevance for future prenatal health.

Loss of control eating during pregnancy is associated with excessive gestational weight gain among individuals with overweight and obesity

BACKGROUND

Excessive gestational weight gain (GWG) predicts negative health outcomes among individuals with overweight or obesity. Loss of control eating (LOC), the ingestion of food associated with being unable to control eating, is the core psychopathology of binge eating disorders. We evaluated the contribution of LOC to GWG among pregnant individuals with prepregnancy overweight/obesity.

METHODS

In a prospective longitudinal study, individuals with prepregnancy BMI ≥ 25 (N = 257) were interviewed monthly to assess LOC and reported demographic, parity, and smoking information. GWG was abstracted from medical records.

RESULTS

Among individuals with prepregnancy overweight/obesity, 39% endorsed LOC prior to or during pregnancy. After adjusting for factors that have previously been linked to GWG, LOC during pregnancy, uniquely predicted higher GWG and greater likelihood of exceeding GWG recommendations. Participants with prenatal LOC gained 3.14 kg (p = 0.03) more than did those without LOC during pregnancy and 78.7% (n = 48/61) exceeded IOM guidelines for GWG. The frequency of LOC episodes was also associated with greater weight gain.

CONCLUSIONS

Prenatal LOC is common among pregnant individuals with overweight/obesity and predicts greater GWG and increased likelihood of exceeding IOM GWG guidelines. LOC may represent a modifiable behavioral mechanism to prevent excessive GWG among individuals at risk for adverse pregnancy outcomes.

Perception of the Body Image in Women after Childbirth and the Specific Determinants of Their Eating Behavior: Cross-Sectional Study (Silesia, Poland)

Background: Episodes of loss of control over eating during pregnancy affect up to 36% of women during this period. Many women experience natural concerns about weight gain and body-shape changes during pregnancy and the postpartum period, and food cravings and fluctuations in eating patterns during these periods are physiological phenomena. However, pregnancy and the postpartum period may be an additional determinant of eating disorders. Women who perceive their own bodies as significantly deviating from the presented ideal are more likely to experience anxiety/anxiety related to it and also tend to exhibit abnormal eating behaviors. The perception of one’s body figure also plays an important role in maintaining psychological balance Aim: The aim of this study was to assess the perception of body image by postpartum women. The essence of the study was to see if there were psychomarkers associated with lack of control over eating, food restriction, and emotionally motivated eating in the study population. Material and methods: The study was conducted during the fall and winter of 2021. A total of 288 women participated in the study. The age of the subjects ranged from 21 to 45 years. Results: It was found that 198 women (68.8%) were dissatisfied with their current body weight and figure. Respondents with higher post-pregnancy body mass index showed dissatisfaction with their body shape (49.8%; H = 13.042; p = 0.001). Both body satisfaction and BMI level were significant components of the occurrence of pathological phenomena associated with the TFEQ-13 subscales (p < 0.05). Conclusions: Excessive focus on food restriction as well as lack of control over eating had some association with negative self-perception of body image, mainly in the form of body weight dissatisfaction. Eating behaviors showed an association with BMI level and weight satisfaction after pregnancy.

Childhood traumatic events and loss of control eating in pregnancy: Findings from a community sample of women with overweight and obesity

Although eating disorder symptoms generally decrease in pregnancy, loss of control eating (LOC), defined by the consumption of food accompanied by a sense of being unable to control what or how much is eaten, often persists and may develop in pregnancy. Given that LOC is associated with higher weight status and psychological distress, it is important to understand factors associated with perinatal LOC. Although childhood traumatic events have been linked to LOC in non-pregnant women, the impact of such events on LOC in pregnancy is unknown. Accordingly, the present study aimed to examine the association between a history of childhood traumatic events and LOC prior to and during pregnancy among a community sample of pregnant women with overweight or obesity. Pregnant women (N = 244) were enrolled in a longitudinal study. Women completed interviews between 12 and 20 weeks gestation to document a history of childhood traumatic events and the presence of LOC in the three months prior to and during their current pregnancy. Women were assessed for LOC monthly for the remainder of pregnancy. Results from a multinomial regression model showed that women with a history of childhood traumatic events had higher odds of engaging in LOC both prior to and during pregnancy (OR = 2.52, 95% CI [1.13, 5.64], p = 0.02) but not during pregnancy only (OR = 1.58, 95% CI [0.87, 2.89], p = 0.39). These findings indicate that women with a history of childhood traumatic events may be especially prone to LOC in the months prior to conception that continues throughout pregnancy.

Documenting the course of loss of control over eating prior to, during and after pregnancy among women with pre-pregnancy overweight and obesity

OBJECTIVE

Loss of control over eating (LOC) is common among women, particularly those with overweight and obesity (OV/OB), and predicts weight gain. Given the importance of understanding weight and eating behaviors during pregnancy, we sought to characterize LOC across pregnancy and the postpartum period among women with pre-pregnancy OV/OB.

METHODS

Pregnant women (N = 257; 28.44 ± 5.48 years old) with self-reported OV/OB prior to pregnancy were interviewed using a pregnancy-adapted version of the Eating Disorder Examination (EDE-PV). Pre-pregnancy LOC was retrospectively assessed during the first trimester and then prospectively assessed monthly throughout pregnancy and postpartum over the course of seven assessments.

RESULTS

Rates of LOC were significantly higher during pregnancy compared to prior to ( χ12 =44.845, p < .01) and after ( χ12 =36.379, p < .01) pregnancy, with 37% (n = 95) of women reporting ≥1 LOC episode during pregnancy. LOC during pregnancy was associated with higher likelihood of LOC postpartum. Higher age (OR = 1.084, p = .04) and identifying as a minority (OR = 0.344, p = .02) was associated with greater likelihood of experiencing LOC during pregnancy only.

DISCUSSION

LOC during pregnancy is common among women with pre-pregnancy OV/OB, suggesting that screening and intervention for LOC during pregnancy may be warranted. Future research is necessary to examine the relationship between LOC during pregnancy and maternal and infant health outcomes.

Eating patterns and unhealthy weight control behaviors are associated with loss-of-control eating following bariatric surgery

BACKGROUND

Loss-of-control (LOC) eating is associated with poor weight-loss outcomes following bariatric surgery. It is not clear whether eating patterns (e.g., total number of daily meals/snacks, eating after suppertime, eating when not hungry) and unhealthy weight control behaviors (e.g., smoking, using laxatives) are associated with or predictive of LOC eating.

OBJECTIVES

To examine whether eating patterns and unhealthy weight-control behaviors are associated with LOC eating and, if so, whether they predict LOC eating in bariatric patients.

SETTING

Multicenter study, United States.

METHODS

This is a secondary analysis of the Longitudinal Assessment of Bariatric Surgery-2 study. Assessments were conducted before surgery and at 12, 24, 36, 48, 60, and 84 months after surgery. Logistic mixed models were used to examine the longitudinal associations between eating patterns, unhealthy weight-control behaviors, and LOC eating. Time-lag techniques were applied to examine whether the associated patterns and behaviors predict LOC eating.

RESULTS

The participants (n = 1477) were mostly women (80%), white (86.9%), and married (62.5%). At the time of surgery, the mean age was 45.4 ± 11.0 years and the mean body mass index was 47.8 ± 7.5 kg/m². The total number of daily meals/snacks, food intake after suppertime, eating when not hungry, eating when feeling full, and use of any unhealthy weight-control behaviors were positively associated with LOC eating (P < .05). Food intake after suppertime, eating when not hungry, and eating when feeling full predicted LOC eating (P < .05).

CONCLUSION

Meal patterns and unhealthy weight control behaviors may be important intervention targets for addressing LOC eating after bariatric surgery.

Impact of binge eating during pregnancy on gestational weight gain and postpartum weight retention among women with gestational diabetes mellitus: LINDA-Brasil

OBJECTIVE

Binge eating (BE) is associated with gestational weight gain, which is a risk factor for gestational diabetes (GDM). Little is known about this association in women with GDM. To evaluate the relationship of BE in pregnancy with gestational weight gain, BE at postpartum and postpartum weight retention in women with GDM.

METHOD

Lifestyle INtervention for Diabetes prevention After pregnancy (LINDA-Brasil) is a multicenter cohort study with 1,958 women with GDM. BE was assessed by interview during recruitment in pregnancy and at a phone interview at ~4 months postpartum. Gestational weight gain was classified according to the 2009 Institute of Medicine (IOM) recommendations. Poisson regression with robust variance was used to estimate adjusted relative risks (RR).

RESULTS

Prevalence of BE was 31.6% (95% confidence interval [CI] 29.5-33.6%) during pregnancy and 30.0% (95% CI 28.0-32.1%) at postpartum. The risk of exceeding the IOM's recommendation for gestational weight gain was 45% higher (RR 1.45, 95% CI 1.29-1.63) in women who had BE during pregnancy compared to those who did not. The risk of having postpartum weight retention above the 75th percentile was 33% higher (RR 1.33, 95% CI 1.10-1.59) among those with BE compared to those without.

DISCUSSION

Among these women with GDM, BE was frequent and was associated with excessive gestational weight gain and weight retention at postpartum. Thus, given the vulnerability of these periods of the life cycle, tracking this eating behavior is important for the management of gestational weight gain and for the prevention of excessive postpartum retention.

Maternal body dissatisfaction in pregnancy, postpartum and early parenting: An overlooked factor implicated in maternal and childhood obesity risk

BACKGROUND

Current evidence indicates that to prevent the intergenerational transfer of overweight and obesity from parent to child, interventions are needed across the early life stages, from preconception to early childhood. Maternal body image is an important but often overlooked factor that is potentially implicated in both short- and long-term maternal and child health outcomes, including maternal gestational weight gain, postpartum weight retention, obesity, child feeding practices and early parenting.

AIM

The aim of this paper is to propose a conceptual model of the relationship between maternal body image (with a specific focus on body dissatisfaction) and maternal and child excess body weight risk across the pregnancy, postpartum and early childhood periods, as well as to highlight opportunities for intervention.

CONCLUSION

Our conceptual model proposes factors that mediate the associations between antenatal and postpartum maternal body dissatisfaction and maternal and childhood obesity risk. Pregnancy and postpartum present key risk periods for excess weight gain/retention and body dissatisfaction. Psychosocial factors associated with maternal body dissatisfaction, including psychopathology and disordered eating behaviours, may increase maternal and child obesity risk as well as compromise the quality of mother-child interactions underpinning child development outcomes, including physical weight gain. Our conceptual model may be useful for understanding modifiable psychosocial factors for preventing the intergenerational transfer of obesity risk from mothers to their children, from as early as pregnancy, and highlights next steps for multidisciplinary research focused on combatting maternal and child obesity during critical risk periods.

Burden and determinants of malnutrition among pregnant women in Africa: A systematic review and meta-analysis

BACKGROUND

Malnutrition in pregnancy remains unacceptably high across all regions of Africa though promising progresses have been made globally. Primary studies might not be sufficient to portrait a comprehensive picture of malnutrition during pregnancy and its main risk factors. Therefore, we intended to review the burden of malnutrition, for this specific review implies to protein energy malnutrition, during pregnancy in Africa to present its magnitude and determinant factors.

METHODS

We did a systematic review of observational studies published from January 1/2008 to January 31/2018. The CINAHL(EBSCO), MEDLINE (via Ovid), Emcare, PubMed databases and Google scholar were searched. Articles quality was assessed using the Newcastle-Ottawa Scale and studies with fair to good quality were included. We pooled malnutrition prevalence and an odds ratio estimates for risk factors after checking for heterogeneity and publication bias. This review has been registered in Prospero with a protocol number CRD42018114949.

RESULT

23 studies involving 20,672 pregnant women were included. Using a random effect model, the overall pooled prevalence of malnutrition among pregnant women in Africa was 23.5% (95%CI: 17.72-29.32; I2 = 98.5%). Based on the current review pooled odds ratio finding; rural residency (POR = 2.6%; 95%CI: 1.48-4.65; I2 = 0%), low educational status of partners (POR = 1.7%; 95%CI: 1.19-2.53; I2 = 54.8%), multiple pregnancy (POR = 2.15%; 95%CI: 1.27-3.64; I2 = 0%) and poor nutritional indicators (POR = 2.03%; 95%CI: 1.72-2.4, I2 = 0%) were positively determine maternal malnutrition. On contrary, better household economic status (POR = 0.47%; 95%CI: 0.36-0.62; I2 = 24.2%) negatively determine maternal malnutrition.

CONCLUSION

A significant number of the pregnant population in Africa are suffering of malnutrition, above 10% of the standard acceptable malnutrition rate. Thus, efforts should be renewed to ensure a proper and widespread implementation of programs that would address issues identified in the current review to reduce the burden of malnutrition.

Giving a good start to a new life via maternal brain allostatic adaptations in pregnancy

Successful pregnancy requires adjustments to multiple maternal homeostatic mechanisms, governed by the maternal brain to support and enable survival of the growing fetus and placenta. Such adjustments fit the concept of allostasis (stability through change) and have a cost: allostatic load. Allostasis is driven by ovarian, anterior pituitary, placental and feto-placental hormones acting on the maternal brain to promote adaptations that support the pregnancy and protect the fetus. Many women carry an existing allostatic load into pregnancy, from socio-economic circumstances, poor mental health and in 'developed' countries, also from obesity. These pregnancies have poorer outcomes indicating negative interactions (failing allostasis) between pre-pregnancy and pregnancy allostatic loads. Use of animal models, such as adult prenatally stressed female offspring with abnormal neuroendocrine, metabolic and behavioural phenotypes, to probe gene expression changes, and epigenetic mechanisms in the maternal brain in adverse pregnancies are discussed, with the prospect of ameliorating poor pregnancy outcomes.

Mother or Father: Who Is in the Front Line? Mechanisms Underlying the Non-Genomic Transmission of Obesity/Diabetes via the Maternal or the Paternal Line

Extensive epidemiological and experimental evidence have shown that exposure to an adverse intrauterine environment as observed in offspring of pregnancies complicated by obesity or diabetes, can program susceptibility to metabolic, endocrine and cardiovascular disorders later in life. Although most studies have concentrated on the maternal environment, it is also becoming evident that paternal exposure to obesity or diabetes can result in the later development of metabolic disorders in the offspring. Such programmed effects might not be limited to the first directly exposed generation, but could be transmitted to subsequent generations. This suggests the existence of mechanisms by which metabolic changes in parental phenotype are transmissible to offspring. The mechanisms which underpin the transmission of the programmed effects across generations are still unclear. However, epigenetic regulation of transcription has emerged as a strong candidate for mediating the heritability of metabolic diseases. Here, we review the most relevant evidence from human and animal studies showing transmission of programming effects of obesity or diabetes across generations, and the current mechanisms underlying either maternal or paternal influences on the metabolic status of offspring.
