Maternal restraint and external eating behaviour are associated with formula use or shorter breastfeeding duration

Associations between pressure to breastfeed and depressive, anxiety, obsessive-compulsive, and eating disorder symptoms among postpartum women

BACKGROUND

Data from qualitative interviews indicate postpartum individuals feel pressure from their healthcare providers, the media, and their partners to breastfeed their infant(s). However, the link between pressure to breastfeed and maternal mental health symptoms has not been evaluated quantitatively. The goal of the current study was to evaluate the associations between perceived pressure to breastfeed from various sources and depressive, anxiety, obsessive-compulsive, and eating disorder symptoms among postpartum individuals.

METHODS

Participants were 306 women, ages 18-39, who gave birth in the past 12 months in the United States (primarily in North Carolina). They completed an online survey about their health history (including mental health symptoms) and breastfeeding experiences.

RESULTS

Results found postpartum women perceived more pressure to breastfeed from healthcare providers and from the media compared to pressure to breastfeed from their partners. Pressure from healthcare providers was associated with depressive, obsessive-compulsive, and eating disorder symptoms, but not with anxiety symptoms. Pressure from the media was associated with only depressive and eating disorder symptoms. Pressure from partners was not significantly associated with mental health symptoms. Above and beyond the other sources of pressure, pressure from healthcare providers explained a unique proportion of variance of obsessive-compulsive and eating disorder symptoms.

LIMITATIONS

Limitations include the cross-sectional design (which limits causal interpretations), and the homogenous sample (87% identified as White).

CONCLUSIONS

Messaging and information about breastfeeding (particularly from healthcare providers) should be reviewed to determine if there is language which could be perceived as "pressure." It is important to screen for a variety of mental health symptoms, including eating disorders, in perinatal populations when discussing breastfeeding.

Food addiction and dietary restraint in postpartum women: The role of childhood trauma exposure and postpartum depression

The early postpartum period is a sensitive time for understanding women's high-risk eating (i.e., eating behavior associated with negative health outcomes) given potential long-term eating behavior implications for infants. Food addiction and dietary restraint are two high-risk eating phenotypes associated with long-term negative health outcomes that have been theoretically linked. Yet, no research has considered how much these constructs overlap during the early postpartum period. The present study sought to characterize these two high-risk eating phenotypes in postpartum women to examine whether these are distinct constructs with specific etiologies and to inform future targets of intervention. Women (N = 277) in the early postpartum period reported on high-risk eating, childhood trauma exposure, depression symptoms, and pre-pregnancy weight. Women's height was measured and pre-pregnancy BMI was calculated. We conducted bivariate correlations and path analysis to characterize the relationship between food addiction and dietary restraint, controlling for pre-pregnancy BMI. Results showed that food addiction and dietary restraint were not significantly associated and that women's childhood trauma exposure and postpartum depression were associated with food addiction but not dietary restraint. Sequential mediation revealed that higher levels of childhood trauma exposure were associated with worse postpartum depression and, in turn, greater food addiction during the early postpartum period. Findings suggest that food addiction and dietary restraint have distinct psychosocial predictors and etiological pathways, which suggests important construct validity differences between the two high-risk eating phenotypes. Interventions seeking to address food addiction in postpartum women and mitigate the impact of this high-risk eating phenotype on the next generation may benefit from treating postpartum depression, especially in women with histories of childhood trauma exposure.

Body Image Dissatisfaction, Breastfeeding Experiences, and Self-Efficacy in Postpartum Women with and Without Eating Disorder Symptoms

BACKGROUND

Women during the postpartum period undergo significant changes which affect body image, eating behaviors, and, potentially, breastfeeding. There is limited research about relationships among these variables, particularly related to breastfeeding experiences and self-efficacy.

RESEARCH AIMS

To determine: (1) the associations between eating disorder symptoms and body image, breastfeeding self-efficacy, and breastfeeding experiences; and (2) the differences in body image, breastfeeding self-efficacy, breastfeeding experiences, and breastfeeding status of postpartum women with and without clinically significant eating disorder symptoms.

METHODS

A secondary data analysis using a 2-group correlational, cross-sectional online survey design was used. Participants with infants 2-6 months old who had breastfed their infant at least once (N = 204) were recruited nationally to complete a cross-sectional survey assessing breastfeeding and postpartum physical and mental health using validated measures. Linear and logistic regression evaluated differences between participants with and without eating disorder symptoms regarding their body image, breastfeeding experience and self-efficacy, and breastfeeding status (continued vs. discontinued) at 2 months postpartum.

RESULTS

Clinical eating disorder symptoms were reported by 9.8% (n = 20). Participants with clinical eating disorder symptoms reported lower appearance evaluations (B = -0.53, 95% CI [-0.93, -0.14]) and body image satisfaction (B = -0.55, 95% CI [-0.87, -0.23]); reduced odds of breastfeeding at 2 months postpartum (AOR = 0.15, 95% CI [0.04, 0.56]); and lower breastfeeding self-efficacy (B = -7.70, 95% CI [-14.82, -0.58] relative to participants without clinical symptoms. No differences between groups were observed for breastfeeding experiences.

CONCLUSIONS

Participants with clinically significant eating disorder symptoms are at risk for early breastfeeding discontinuation and lower breastfeeding self-efficacy. Our findings have implications for future research and clinical care practices, including screening for body image concerns and eating disorder symptoms and supporting breastfeeding self-efficacy.

Infant Feeding Varies Across Eating Behavior and Feeding Modalities in Mothers With Low Income

OBJECTIVE

To examine if eating behaviors in mothers with low income relate to attitudes toward infant feeding and whether associations differed between breastfeeding and formula-feeding mothers.

DESIGN

Cross-sectional study.

PARTICIPANTS

Forty postpartum women (aged ≥ 18 years, body mass index ≥ 25 and < 40 kg/m²) in the Louisiana Women, Infants, and Children program participated in a telehealth postpartum intervention for health and weight loss.

MAIN OUTCOME MEASURE(S)

Maternal eating behaviors and infant feeding styles, assessed 6-8 weeks after birth (baseline) using validated questionnaires.

ANALYSIS

Significance was detected using independent t tests, chi-square tests for independence, or linear models (P < 0.05).

RESULTS

Most mothers formula-fed (n = 27, 68%). In formula-feeding mothers, maternal disinhibition and perceived hunger were positively associated with restrictive infant feeding (β = 0.41, P <0.001 and β = 0.41, P = 0.001, respectively). These relationships were significantly higher (Δ = -0.85, P = 0.006 and Δ = -0.59, P = 0.003, respectively) than among breastfeeding mothers. Comparatively, pressuring/overfeeding was lower in formula-feeding mothers than among breastfeeding mothers with dietary restraint (Δ slopes: 1.06, P = 0.02).

CONCLUSIONS AND IMPLICATIONS

In this cohort of mothers with low income, maternal eating behavior was associated with infant feeding styles only when feeding modality was considered. Mothers may benefit from education on how their eating behaviors can influence their infants and children.

Breastfeeding, body image, and weight control behavior among postpartum women

The goal of this study was to examine breastfeeding behavior and attitudes as predictors of women's body image and weight control behavior. This study extends past research by focusing on positive body image variables including body appreciation and perceived body functionality. Women (N = 597) from the United States who had recently birthed biological babies ages 0-12 months participated in an online study. Current breastfeeding rates were high (86 %), and average breastfeeding duration was approximately 3 months. Women who were currently breastfeeding indicated more positive body images and less likelihood of engaging in maladaptive weight control behaviors than women who were no longer breastfeeding or had never breastfed their baby. Women's positive attitudes toward breastfeeding were associated with awareness and appreciation of body functionality and fewer maladaptive weight control behaviors. These findings extend research on the health benefits of positive body image and suggest that breastfeeding may occur within a constellation of beliefs and behaviors indicative of positive body image.

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.

Associations between bottle-feeding intensity and maternal encouragement of bottle-emptying

Objective

To explore longitudinal associations between bottle-feeding and maternal encouragement of infant bottle-emptying during the first 6 months of infancy.

Design

Mothers completed questionnaires during the third trimester of pregnancy, then monthly during the first 6 months postpartum. Questionnaires assessed family demographics, maternal and infant weight status, infant feeding patterns and maternal encouragement of infant bottle-emptying.

Setting

The Infant Feeding Practices Study 2, conducted by the US Centers for Disease Control and Prevention and the Food and Drug Administration.

Subjects

Mothers (n 1776).

Results

Repeated-measures regression was used to explore associations between bottle-feeding intensity (BFI; defined as the percentage of daily feedings that were from a bottle) and encouragement of bottle-emptying. Mothers who reported consistently high or consistently low BFI also exhibited consistently higher or lower frequency of encouraging their infants to empty the bottle (respectively) across the first 6 months of infancy, whereas mothers who reported increases in their BFI also exhibited concomitant increases in the frequency to which they encouraged their infants to finish the bottle. More frequent encouragement of bottle-emptying was also associated with feeding expressed breast milk (P<0·001), and lower parity (P=0·01), pre-pregnancy BMI (P=0·002) and infant birth weight (P=0·001).

Conclusions

More frequent use of bottles for infant feeding was significantly associated with more frequent encouragement of bottle-emptying. Further research using causal designs is needed to better understand whether the use of bottles promotes this controlling feeding practice or whether mothers with more controlling feeding practices opt to bottle-feed.

Body Image, Eating Attitudes and Breastfeeding Intention: Implications for Mental Health and Maternal Child Nurses

Body image dissatisfaction and disordered eating are often overlooked as personal factors that may affect pregnancy, postpartum, and infant feeding method. The current study compared body image, eating attitudes, and breastfeeding intention of first-time breastfeeding mothers to first-time non-breastfeeding mothers. A two-group, comparative design was used to analyze data for first-time mothers recruited through a large pediatric practice with multiple offices. Although there was no significant difference in body image scores between the groups, the literature suggests that body image dissatisfaction can affect the transition to motherhood and lead to more serious mental health issues. Prevention of psychiatric disorders such as eating disorders can be addressed early with information regarding body dissatisfaction and disordered eating. Findings from this study have implications for mental health and maternal child health providers.

Associations between Breastfeeding and Maternal Responsiveness: A Systematic Review of the Literature

Recent recommendations and prevention programs have focused on the promotion of responsive feeding during infancy, but more research is needed to understand best practices for fostering responsive feeding during early life. The objective of this systematic review was to synthesize the accumulating bodies of evidence aimed at understanding associations between mothers' feeding experiences and responsive feeding in an attempt to clarify the nature of associations between feeding mode and responsive feeding. A literature search was conducted between January and October 2016; articles were collected from PsychINFO, Medline, and CINAHL, as well as from references in published research and reviews. Article inclusion criteria were as follows: 1) empirical research, 2) included a measure of infant feeding, 3) included a measure of maternal responsiveness, 4) study conducted in human participants, 5) available in English, and 6) study conducted in a developed and/or high-income country. Forty-three studies were identified. Cross-sectional observational studies consistently reported greater responsiveness among breastfeeding mothers than among formula-/bottle-feeding mothers. In addition, longitudinal studies showed that longer breastfeeding durations predicted lower use of nonresponsive feeding practices during later childhood, and some, but not all, found that breastfeeding mothers showed greater increases in responsiveness across infancy than did formula-/bottle-feeding mothers. However, a limited number of longitudinal studies also reported that greater responsiveness during early infancy predicted longer breastfeeding durations. A common limitation among these studies is the correlational nature of their designs and lack of prenatal measures of maternal responsiveness, which hinders our understanding of causal mechanisms. Although 2 randomized clinical trials aimed at promoting maternal responsiveness did not find effects of the intervention on breastfeeding outcomes, these findings were limited by the way in which breastfeeding outcomes were assessed. In sum, although there is consistent evidence for an association between breastfeeding and responsive feeding, more research is needed to better understand the mechanisms underlying this association.

Differences in eating behaviour, well-being and personality between mothers following baby-led vs. traditional weaning styles

Baby-led weaning, where infants self-feed family foods in place of traditional spoon-feeding of purees, is continuing to grow in popularity. Evidence is emerging which suggests that the method may promote healthier eating behaviour and weight gain in children, but the research is in its infancy. One issue is the self-selecting nature of participants to the approach. Although those who follow a baby-led approach are known to have a higher education and more professional occupation, little is known about wider maternal characteristics, which might affect either adoption of or outcomes of the method. The aim of this study was to explore differences in maternal characteristics between those adopting a baby-led or traditional approach. Six hundred four mothers with an infant aged 6-12 months completed a questionnaire including a copy of the Dutch Eating Behaviour Questionnaire (DEBQ), Brief Symptom Inventory (BSI) (anxiety, obsessive-compulsive and depression scales) and Ten Item Personality Questionnaire (TIPQ) alongside details of weaning approach (baby-led vs. traditional). Mothers who adopted a baby-led weaning style scored significantly lower on restrained eating (DEBQ), anxiety and introversion (TIPQ) and anxiety and obsessive-compulsive symptoms (BSI). Mothers who currently adopt a baby-led approach are therefore significantly different in personality, eating behaviour and well-being characteristics compared with those adopting a traditional approach. These characteristics may affect likelihood of choosing a baby-led approach or indirectly affect outcomes for infants weaned using the approach. Further research exploring baby-led weaning in a wider population sample is needed.

Mothers’ restrictive eating and food neophobia and fathers’ dietary quality are associated with breast-feeding duration and introduction of solid foods: the STEPS study

Objective

The purpose of the present study was to examine the association between parental eating behaviours and dietary patterns and feeding practices of infants and young children.

Design

Data on infant-feeding practices were collected from each infant’s birth via parentally self-administered follow-up diaries. Three questionnaires, the Three-Factor Eating Questionnaire, the Food Neophobia Scale and the Index of Diet Quality, were administered when the children were aged 4 and 13 months.

Setting

South-western Finland.

Subjects

Families participating in the STEPS longitudinal cohort study (n1797).

Results

Mean duration of exclusive breast-feeding was 2·4 months and total duration of breast-feeding averaged 8·1 months. The first solid food was introduced into children’s diets at the age of 3·9 months, on average. Mothers with highly restrictive eating were more likely to introduce solid foods sooner than mothers who ranked lower in these behaviours (3·8 monthsv.4·0 months,P=0·012). Neophobic mothers breast-fed exclusively (2·0v. 2·6 months,P=0·038) and in total (7·2v. 8·5 months,P=0·039) for shorter times than average mothers, even after adjusting for various demographic characteristics. Fathers’ diet quality was associated with total breast-feeding duration and with introduction of complementary foods in unadjusted analyses and with total breast-feeding duration also after adjusting for confounding factors.

Conclusions

Mothers’ and fathers’ eating patterns and practices are associated with the feeding practices of infants and young children. Health promotion interventions seeking to improve parents’ eating patterns might lead to more favourable feeding practices for infants and young children.
