目的确定三个民族的低收入mothers.Design一个为期8周的饮食和体力活动计划的体重减轻的预测。在基线时收集人口统计学数据;在基线和第8周测量人体测量、饮食、体力活动和心理社会数据。受试者/设置114名西班牙裔、非裔美国人和白色低收入母亲的便利样本，体重指数>= 25（以kg/m2计算）参与干预。干预减肥课程，包括营养，体育活动，主要结果测量人体测量学（体重，体重减轻），进行方差分析，卡方检验，以及斯皮尔曼和皮尔逊相关性用于检验基线和变化数据与总体重减轻之间的关联。采用分层回归分析方法对社会经济因素以外的影响因素进行边际重要性评估。结果与体重减轻相关的因素包括对外观的满意度降低（r=0.24），蛋白质能量的百分比更大（r=-0.22），营养知识提高（r=-0.23），基线时体重减轻的益处评分较高（r=-0.20）; 8周时健康饮食态度（r=-0.28）和社会支持（r=-0.21）的变化。基线和变化变量的预测模型分别代表11.4%和13.8%的variations.Conclusions体重管理计划服务于低收入的母亲应该提供技术，以提高社会支持，对健康饮食的态度，减肥的好处，营养知识。
Objective To identify predictors of weight loss in a tri-ethnic population of low-income mothers.Design An 8-week dietary and physical activity program was tested. Demographic data were collected at baseline; anthropometric, dietary, physical activity, and psychosocial data were measured at baseline and week 8.Subjects/setting A convenience sample of 114 Hispanic, African-American, and white, low-income mothers with a body mass index >= 25 (calculated as kg/m(2)) participated in the intervention.Intervention Weight-loss classes that incorporated nutrition, physical activity, and behavior modification were administered for 8 weeks.Main outcome measures Anthropometry (body weight, weight loss).Statistical analyses performed Analysis of variance, chi(2) tests, and Spearman and Pearson correlations were used to test for associations between baseline and change data and total weight loss. Hierarchical regression was employed to assess the marginal importance of factors beyond socioeconomic influences.Results Correlates of weight loss included less satisfaction with appearance (r=0.24), greater percentage of energy from protein (r=-0.22), enhanced nutrition knowledge (r=-0.23), and higher scores for benefits of weight loss (r=-0.20) at baseline; and the change in healthful eating attitudes (r=-0.28) and social support (r=-0.21) at 8 weeks. The predictive models of baseline and change variables represented 11.4% and 13.8% of the variance, respectively.Conclusions Weight-management programs serving low-income mothers should provide techniques to enhance social support, attitudes toward healthful eating, benefits of weight loss, and nutrition knowledge.
