The purpose of this study was to evaluate a nutrition and physical activity program for reducing body weight and improving nutrition attitudes in mothers of young children. A convenience sample of 114 intervention mothers and 33 comparison mothers was recruited from public health clinics and community centers. Eligibility criteria included Hispanic, African American, or white ethnicity; body mass index of at least 25 kg/m(2); low income (< 200% of the federal poverty index); and youngest child aged 1 to 4 years. For intervention participants, height, weight, percentage of body fat, waist circumference, demographics, nutrition attitudes, and dietary intake were measured at weeks 0 and 8; height, weight, percentage of body fat, and waist circumference were reassessed at 6 months. Overweight mothers in the comparison group provided anthropometric and demographic data at weeks 0 and 8. Changes in anthropometrics, attitudes, and dietary intake were evaluated in intervention mothers. Anthropometric data of intervention vs comparison group mothers were examined. Differences in anthropometrics and attitude scores between weight loss responders (> or = 2.27 kg) and nonresponders (< 2.27 kg) were assessed at week 8. Intervention participants lost weight (x = -2.7 kg; P < .001), whereas comparison mothers gained a slight amount of weight (x = 0.1 kg) by week 8. Weight loss responders had healthier eating attitudes (5.6 vs 5.2; P < .01) and fewer perceived barriers (2.4 vs 2.9; P < .05) than nonresponders postintervention. In conclusion, this dietary and physical activity curriculum is a valuable resource for weight management programs serving low-income women.
本研究的目的是评估一项营养与体育活动计划，该计划旨在减轻幼儿母亲的体重并改善她们的营养观念。从公共卫生诊所和社区中心招募了114名干预组母亲和33名对照组母亲作为便利样本。入选标准包括西班牙裔、非裔美国人或白人种族；体重指数至少为25 kg/m²；低收入（低于联邦贫困指数的200%）；以及最小的孩子年龄在1至4岁之间。对于干预组参与者，在第0周和第8周测量身高、体重、体脂百分比、腰围、人口统计学特征、营养观念和饮食摄入量；在6个月时重新评估身高、体重、体脂百分比和腰围。对照组中的超重母亲在第0周和第8周提供人体测量学和人口统计学数据。对干预组母亲的人体测量学、观念和饮食摄入量的变化进行了评估。检查了干预组与对照组母亲的人体测量学数据。在第8周评估体重减轻反应者（≥2.27 kg）和无反应者（<2.27 kg）之间人体测量学和观念得分的差异。到第8周时，干预组参与者体重减轻（x=-2.7 kg；P<.001），而对照组母亲体重略有增加（x=0.1 kg）。与干预后无反应者相比，体重减轻反应者具有更健康的饮食观念（5.6对5.2；P<.01）和更少的感知障碍（2.4对2.9；P<.05）。总之，这种饮食和体育活动课程对于为低收入女性服务的体重管理计划是一种宝贵的资源。
