目标。检查健康饮食随机对照试验中母亲的干预效果。此外，检查个人和家庭的影响观察结果的中介作用。方法.在2009年至2011年期间，招募了361个家庭，其中一半被分配到一个11个会议的社区卫生工作者提供的家庭为基础的干预，针对西班牙语的拉丁美洲家庭在帝国县，加州。干预措施在4个月内实施。大约每周进行一次家访和电话访问，在接近干预结束时逐渐减少，以促进独立于promotora。在这篇文章中，母亲自我报告的饮食摄入量是主要结果。在基线、4个月和10个月时进行评价。结果基线后10个月，干预组母亲的每日水果摄入量高于对照组母亲（平均值= 1.86 vs.平均值= 1.47;效应量[ES] = 0.22）。干预组与对照组的母亲还报告说，从脂肪中摄取的能量百分比较低（平均值= 30.0% vs. 31.0%; ES = 0.30），饮食质量较高（平均值= 2.93 vs.平均值= 2.67; ES = 0.29）。改善的中介因素是增加纤维和降低脂肪摄入量的行为策略，家庭对蔬菜购买的支持，以及减少不健康的饮食行为和健康饮食的家庭障碍。讨论和结论。以家庭为基础的行为干预是有效的改变技能和家庭系统需要改善拉丁裔母亲的饮食。鼓励卫生保健提供者和其他从业人员以技能发展为目标，培养社会支持性环境。
Aims. Examine intervention effects among mothers involved in a healthy eating randomized controlled trial. Furthermore, examine the mediating roles of individual and familial influences on observed outcomes. Methods. Between 2009 and 2011, 361 families were recruited; half were assigned to an 11-session community health worker-delivered family-based intervention targeting Spanish-speaking Latino families in Imperial County, California. The intervention was delivered over a 4-month period. Home visits and telephone calls were delivered approximately weekly, with tapering near the end of the intervention to promote independence from the promotora. In this article, mothers' self-reported dietary intake was the primary outcome. Evaluation measures were taken at baseline, 4 months, and 10 months. Results. Daily servings of fruits were higher among intervention versus control mothers (mean = 1.86 vs. mean = 1.47; effect size [ES] = 0.22) at 10 months post-baseline. Mothers in the intervention versus control condition also reported consuming a lower percent energy from fat (mean = 30.0% vs. 31.0%; ES = 0.30) and a higher diet quality (mean = 2.93 vs. mean = 2.67; ES = 0.29). Mediators of improvements were behavioral strategies to increase fiber and lower fat intake, family support for vegetable purchasing, and decreased unhealthy eating behaviors and perceived family barriers to healthy eating. Discussion and Conclusion. Family-based behavioral interventions are effective for changing the skills and family system needed to improve diet among Latina mothers. Health care providers and other practitioners are encouraged to target skill development and fostering a socially supportive environment.
