Introduction. Delta Healthy Sprouts trial was designed to test the comparative impact of two home visiting programs on weight status, dietary intake, and health behaviors of Southern African American women and their infants. Results pertaining to the primary outcome, gestational weight gain, are reported. Methods. Participants (n = 82), enrolled early in their second trimester of pregnancy, were randomly assigned to one of two treatment arms. Gestational weight gain, measured at six monthly home visits, was calculated by subtracting measured weight at each visit from self-reported prepregnancy weight. Weight gain was classified as under, within, or exceeding the Institute of Medicine recommendations based on prepregnancy body mass index. Chi-square tests and generalized linear mixed models were used to test for significant differences in percentages of participants within recommended weight gain ranges. Results. Differences in percentages of participants within the gestational weight gain guidelines were not significant between treatment arms across all visits. Conclusions. Enhancing the gestational nutrition and physical activity components of an existing home visiting program is feasible in a high risk population of primarily low income African American women. The impact of these enhancements on appropriate gestational weight gain is questionable given the more basic living needs of such women. This trial is registered with ClinicalTrials.gov NCT01746394, registered 4 December 2012.
引言。“三角洲健康萌芽”试验旨在测试两种家庭访视项目对非裔美国南方女性及其婴儿的体重状况、饮食摄入和健康行为的比较影响。本文报告了与主要结局即孕期体重增加相关的结果。方法。研究对象（n = 82）在妊娠中期早期入组，被随机分配至两个治疗组之一。孕期体重增加通过每次家访时测量的体重减去自我报告的孕前体重来计算，每六个月进行一次家访测量。根据孕前体重指数，体重增加被分类为低于、处于或超过医学研究所的建议范围。采用卡方检验和广义线性混合模型来检验处于推荐体重增加范围内的参与者百分比的显著差异。结果。在所有访视中，两个治疗组之间处于孕期体重增加指南范围内的参与者百分比差异不显著。结论。在主要为低收入非裔美国女性的高风险人群中，加强现有家庭访视项目中的孕期营养和身体活动部分是可行的。鉴于这类女性更基本的生活需求，这些强化措施对适当孕期体重增加的影响值得怀疑。本试验已在ClinicalTrials.gov注册，注册号为NCT01746394，于2012年12月4日注册。
