This intervention sought to promote healthy eating with the ultimate goal of reducing childhood obesity risk.
Three hundred and sixty-one Latino families living on the US-Mexico border with at least one child between 7-13 years of age were eligible to participate. Families randomly assigned to the four-month intervention received 14 contacts with a promotora (community health worker), consisting of 11 home visits and three telephone calls; the control condition was a delayed treatment intervention. Children reported on their dietary intake at baseline, immediately post-intervention and at the six month follow-up visit.
The intervention reduced weekly consumption of fast food (p<0.05). A dose-response relationship was observed such that for every seven hours of promotora contact, monthly variety of fruits (p<0.01) and vegetables (p<0.01) increased by one. No other intervention effects were observed.
Family-based interventions can improve children's eating habits, with the amount of contact with the promotora being key to success.
本干预措施旨在促进健康饮食,最终目标是降低儿童肥胖风险。
居住在美国与墨西哥边境的361个拉丁裔家庭符合参与条件,每个家庭至少有一名7至13岁的儿童。随机分配到为期四个月干预组的家庭会与一名社区健康工作者进行14次接触,包括11次家访和3次电话访问;对照组则是延迟治疗干预。孩子们在基线、干预结束后立即以及六个月随访时报告他们的饮食摄入量。
干预措施减少了快餐的每周消费量(p<0.05)。观察到一种剂量反应关系,即每与社区健康工作者接触7小时,每月水果(p<0.01)和蔬菜(p<0.01)的种类就增加一种。未观察到其他干预效果。
基于家庭的干预措施可以改善儿童的饮食习惯,与社区健康工作者的接触量是成功的关键。
