Promoting weight loss among overweight low-income postpartum women has proven difficult. The study's aims were to pilot-test ethnic-specific weight-loss interventions using randomized control-group designs for White/Anglo (n = 23), African American (n = 25), and Hispanic low-income postpartum women (n = 23) and draw lessons from psychosocial data and follow-up interviews. Interventions lasting 13 weeks were offered in group settings in the community. Similar to other randomized trials with low-income mothers, weight changes between intervention and control groups were nonsignificant in each ethnic group; however, changes correlated significantly with self-efficacy (Spearman r = .50) for White/Anglo women and self-efficacy (Spearman r = -.48) and perceived stress (Spearman r = .48) for African American women. In follow-up interviews, women felt interventions gave a good foundation for weight loss, but program and situational factors affected participation and weight loss. Control groups (mailed interventions later) were generally more pleased with their assignment than intervention groups.
事实证明,促进超重低收入产后女性减肥很困难。该研究的目的是采用随机对照组设计,对白人/盎格鲁(n = 23)、非裔美国人(n = 25)和西班牙裔低收入产后女性(n = 23)进行特定种族的减肥干预试点测试,并从心理社会数据和随访访谈中吸取经验教训。在社区的集体环境中提供为期13周的干预措施。与其他针对低收入母亲的随机试验类似,每个种族组中干预组和对照组之间的体重变化均无显著差异;然而,白人/盎格鲁女性的体重变化与自我效能感显著相关(斯皮尔曼相关系数r = 0.50),非裔美国女性的体重变化与自我效能感(斯皮尔曼相关系数r = -0.48)和感知压力(斯皮尔曼相关系数r = 0.48)显著相关。在随访访谈中,女性认为干预措施为减肥奠定了良好基础,但项目和情境因素影响了参与度和减肥效果。对照组(后来邮寄干预措施)通常比干预组对自己的分组更满意。
