Feasibility and Initial Efficacy Evaluation of a Community-Based Cognitive-Behavioral Lifestyle Intervention to Prevent Excessive Weight Gain During Pregnancy in Latina Women

Abstract

About 48 % of US women gain more weight during pregnancy than recommended by the Institute of Medicine (IOM). Excessive gestational weight gain is a major risk factor for obesity in both women and offspring over their lifetimes, and should be avoided. This study was designed to test the feasibility and initial efficacy of a prenatal behavioral intervention in a sample of low-income, predominantly Latina women. The intervention was delivered in groups of 8–10 women in a community recreation center, and structured to reduce the proportion of women who gained weight in excess of IOM guidelines. Recruitment targets were met in 3 months: 135 pregnant women (>10 and <28 weeks) were randomly assigned to receive a 12-week intervention (n = 68) or usual care (n = 67). Retention rate was 81 %. On average, women attended 4 of 12 group sessions, and each session had 4 of the 8–10 assigned participants in attendance. Initial efficacy analyses were based on 87 women. Compared to usual care, fewer normal-weight women in the intervention exceeded IOM recommendations (47.1 % usual care vs. 6.7 % intervention; absolute difference 40.4 %; p = .036). Recommendations for recruitment, retention, and delivery are discussed. A community-based cognitive-behavioral lifestyle intervention during pregnancy was feasible in a hard-to-reach, high-risk population of low-income Latina women, and showed efficacy in preventing excessive gestational weight gain. Due to frequently changing work schedules, strategies are needed to either increase attendance at group sessions (e.g., within a group prenatal care format) or to build core skills necessary for behavior change through other modalities.Electronic supplementary materialThe online version of this article (doi:10.1007/s10995-015-1698-x) contains supplementary material, which is available to authorized users.

Community-based exercise interventions during pregnancy are perceived as a satisfactory and motivating form of exercise engagement

“…Studies exploring benefits of antenatal exercise are numerous, with several having focused on the provision and acceptability of exercise classes. Other approaches have also been explored, such as cognitive–behavioural lifestyle interventions1 and behaviour change interventions,2 as well as those with a dietary and nutritional focus 3…”

Family Support and Family Negativity as Mediators of the Relation between Acculturation and Postpartum Weight in Low-Income Mexican-Origin Women

“…Multiple intervention efforts have been developed to increase healthy behaviors and promote healthy weight in the postpartum period among Mexican-origin women (58–59). Our results highlight the key role that cultural and family characteristics should play in designing, targeting, and implementing these interventions.…”
