A qualitative study of factors affecting pregnancy weight gain in African American women

Racial/Ethnic Disparities in Inadequate Gestational Weight Gain Differ by Pre-pregnancy Weight

Pre-pregnancy body mass index (BMI) varies by race/ethnicity and modifies the association between gestational weight gain (GWG) and adverse pregnancy outcomes, which disproportionately affect racial/ethnic minorities. Yet studies investigating whether racial/ethnic disparities in GWG vary by pre-pregnancy BMI are inconsistent, and none studied nationally representative populations. Using categorical measures of GWG adequacy based on Institute of Medicine recommendations, we investigated whether associations between race/ethnicity and GWG adequacy were modified by pre-pregnancy BMI [underweight (<18.5 kg/m(2)), normal weight (18.5-24.9 kg/m(2)), overweight (25.0-29.9 kg/m(2)), or obese (≥30.0 kg/m(2))] among all births to Black, Hispanic, and White mothers in the 1979 USA National Longitudinal Survey of Youth cohort (n = 6,849 pregnancies; range 1-10). We used generalized estimating equations, adjusted for marital status, parity, smoking during pregnancy, gestational age, and multiple measures of socioeconomic position. Effect measure modification between race/ethnicity and pre-pregnancy BMI was significant for inadequate GWG (Wald test p value = 0.08). Normal weight Black [risk ratio (RR) 1.34, 95 % confidence interval (CI) 1.18, 1.52] and Hispanic women (RR 1.33, 95 % CI 1.15, 1.54) and underweight Black women (RR 1.38, 95 % CI 1.07, 1.79) experienced an increased risk of inadequate GWG compared to Whites. Differences in risk of inadequate GWG between minority women, compared to White women, were not significant among overweight and obese women. Effect measure modification between race/ethnicity and pre-pregnancy BMI was not significant for excessive GWG. The magnitude of racial/ethnic disparities in inadequate GWG appears to vary by pre-pregnancy weight class, which should be considered when designing interventions to close racial/ethnic gaps in healthy GWG.

A qualitative study exploring pregnant women's weight-related attitudes and beliefs in UK: the BLOOM study

BACKGROUND

There is little information on the individual cognitive, perceptual and psychosocial factors that influence the lifestyle behaviours of pregnant women. This study explored pregnant women's weight-related attitudes and beliefs during pregnancy.

METHODS

Nineteen pregnant women with different pre-pregnancy BMIs and in their third trimester were purposefully sampled for face-to-face interviews. Topics covered included lifestyles, sources of information, feelings about their bodies, and level of control over themselves and their bodies. Systematic thematic content analysis was used to identify recurrent themes.

RESULTS

Women perceived their bodies as fragmented into 'my pregnancy' (the bump) and 'me' (rest of my body). This fragmentation was the key driver of their weight-related attitudes and beliefs and influenced their dietary and physical activity behaviours. Consuming healthy foods was necessary for 'my pregnancy' to provide the ideal gestational environment. Simultaneously, pregnancy was perceived as a time to relax previously set rigid rules around diet and physical activity, allowing women to consume unhealthy foods and lead sedentary lifestyles. Women faced emotional conflicts between limiting weight gain for 'me', and being perceived as acting morally by gaining enough weight for 'baby'. Although 'bump' related weight gain was acceptable, weight gain in other parts of their body was viewed negatively and implied lack of self-control. Conflict was often alleviated, and weight-related behaviours validated, by seeking practical and reputable information for weight management. Women felt that their midwives provided detailed information on what they should not do during pregnancy, but were rarely given information about what they should do in relation to diet and physical activity for weight management. Consequently, women often used information from a variety of sources which they filtered using 'common sense'.

CONCLUSIONS

This study has identified that a central concept to pregnant women's diet and physical activity beliefs during pregnancy is the fragmentation of self into 'me' and 'my pregnancy'. This fragmentation influenced beliefs about diet and physical activity, and control and acceptability of gestation weight gain on different parts of the body. Future interventions and antenatal care should take this fragmentation into consideration when providing pregnant women with advice, information and support relating to their diet and physical activity behaviours.

Potential for a stress reduction intervention to promote healthy gestational weight gain: focus groups with low-income pregnant women

BACKGROUND

Prepregnancy body mass index and excessive gestational weight gain (GWG) are associated with adverse maternal and infant outcomes. Because stress contributes to obesity and eating behaviors, stress reduction interventions during pregnancy may be a novel way to influence GWG, positively affect maternal and infant outcomes, and address the obesity epidemic intergenerationally.

METHODS

Our research team is developing a mindfulness-based stress reduction and nutrition intervention for low-income, overweight and obese pregnant women, with healthy GWG as the primary outcome measure. To inform development of the intervention, we conducted focus groups with our target population. Focus group transcripts were analyzed for themes related to sources and importance of stress, relationship between stress and eating, and motivation for a stress reduction pregnancy intervention.

FINDINGS

Fifty-nine low-income pregnant women from the San Francisco Bay Area participated in focus groups and completed a questionnaire. The vast majority of women (80%) reported experiencing significant stress from a variety of sources and most recognized a relationship between stress and eating in their lives.

CONCLUSIONS

This at-risk population seems to be extremely interested in a stress reduction intervention to support healthy GWG during pregnancy. The women in our groups described high levels of stress and a desire for programs beyond basic dietary recommendations. These findings inform practitioners and policymakers interested in pregnancy as a "window of opportunity" for behavior change that can affect the metabolic and weight trajectory both for women and their offspring.

A qualitative study of motivators and barriers to healthy eating in pregnancy for low-income, overweight, African-American mothers

Poor diet quality is common among low-income, overweight, African-American mothers, placing them at high risk for adverse pregnancy outcomes. We sought to better understand the contextual factors that may influence low-income African-American mothers' diet quality during pregnancy. In 2011, we conducted semi-structured interviews with 21 overweight/obese, pregnant African Americans in Philadelphia, PA, all of whom received Medicaid and were eligible for the Special Supplemental Nutrition Program for Women, Infants, and Children. Two readers independently coded the interview transcripts to identify recurrent themes. We identified 10 themes around motivators and barriers to healthy eating in pregnancy. Mothers believed that consuming healthy foods, like fruits and vegetables, would lead to healthy babies and limit the physical discomforts of pregnancy. However, more often than not, mothers chose foods that were high in fats and sugars because of taste, cost, and convenience. In addition, mothers had several misconceptions about the definition of healthy (eg, "juice is good for baby"), which led to overconsumption. Many mothers feared they might "starve" their babies if they did not get enough to eat, promoting persistent snacking and larger portions. Living in multigenerational households and sharing resources also limited the mothers' control over food choices and made consuming healthy foods especially difficult. Despite the good intentions of low-income African-American mothers to improve diet quality during pregnancy, multiple factors worked together as barriers to healthy eating. Interventions that emphasize tasty and affordable healthy food substitutes, address misconceptions, and counsel mothers about true energy needs in pregnancy may improve low-income, African-American, overweight/obese mothers' diet quality.
