目的：描述Abriendo Caminos预防儿童超重增加的以家庭为中心的文化定制项目的方法论。设计：随机对照试验，在干预前、后和干预后6个月或缩短注意控制组进行结果评估。设置：5个地点(伊利诺伊州、加利福尼亚州、爱荷华州、德克萨斯州和波多黎各)的社区环境。参与者：墨西哥裔美国人和波多黎各家庭(父母和1名6-18岁的孩子)。每个地点100个家庭(50个干预和50个对照)的样本大小将提供足够的力量来检测干预效果。干预：家庭将参加每周6个、2小时的小组研讨会，通过陈述和活动、家庭健康和体育活动相结合的方式进行营养教育。主要观察指标：主要结果是防止儿童超重；次要结果包括儿童饮食的变化，特别是水果、蔬菜和含糖饮料的消费，以及父母饮食的变化和家庭日常生活的改善。将在基线、干预后和6个月后收集测量。分析：将使用标准方法检查评估试验组内部和之间变化的建模，包括评估模型拟合、影响诊断、调整后的R-2和多重共线性。效应的重要性将使用III型测试来检验。
Objective: To describe the methodology of a family-focused, culturally tailored program, Abriendo Caminos, for the prevention of excess weight gain in children.Design: Randomized control trial with outcome assessment at pretest, posttest, and 6 months after intervention or abbreviated-attention control group.Setting: Community setting across 5 sites (Illinois, California, Iowa, Texas, and Puerto Rico).Participants: Mexican American and Puerto Rican families (parent and 1 child aged 6-18 years). A sample size of 100 families (50 intervention and 50 control) per site (n = 500) will provide adequate power to detect intervention effects.Intervention: Families will participate in 6 weekly, 2-hour group workshops on nutrition education through combined presentations and activities, family wellness, and physical activity.Main Outcome Measures: The primary outcome is prevention of excess weight gain in children; secondary outcomes include changes in child diet, specifically fruit, vegetable, and sugar-sweetened beverage consumption, and changes in parents' diets and improvement of family routines. Measures will be collected at baseline, postintervention, and 6 months after.Analysis: Modeling to assess changes within and between experimental groups will be checked using standard methods including assessment of model fit, influence diagnostics, adjusted R-2, and multicollinearity. Significance of effects will be examined using Type III tests.
