The High 5, Low Fat Program (H5LF) for African American parents was developed in partnership with the Parents As Teachers program, and was designed to test a dietary intervention appropriate for national adoption.
H5LF used a group randomized, nested cohort design with 738 parents. Consistent with organizational goals and methods, parent educators delivered a dietary change program via personal visits, newsletters, and group meetings. Primary outcomes were reducing percentage calories from fat and increasing fruit and vegetable consumption among participating parents; intermediate aims included improving in nutrition-related skills and parental modeling of dietary behaviors.
H5LF parents achieved a 0.53 increase in fruit and vegetable consumption (P = 0.03), and a higher proportion of H5LF parents reduced their intake to less than 30% calories from fat (chi(2) = 4.8, P < 0.03; -1.7% calories from fat, p = 0.07) and improved performance of dietary behaviors (F = 14.2, P = 0.004). Improvements in parental modeling were not statistically significant.
H5LF is an effective intervention that is appropriate for national adoption by over 2000 Parents As Teachers sites with the potential to impact dietary intake of African American parents nationwide.
针对非裔美籍父母的“高五低脂计划”(H5LF)是与“家长即教师”计划合作开展的,旨在测试一项适合全国推广的饮食干预措施。
H5LF采用了群组随机嵌套队列设计,涉及738名家长。根据组织目标和方法,家长教育工作者通过个人家访、时事通讯和小组会议开展饮食改变计划。主要成果是降低参与计划的家长饮食中脂肪的热量占比,增加水果和蔬菜的摄入量;中间目标包括提高与营养相关的技能以及家长在饮食行为方面的示范作用。
H5LF计划实施后,家长的水果和蔬菜摄入量增加了0.53(P = 0.03),更多的H5LF计划参与者将脂肪热量摄入量降至30%以下(卡方值=4.8,P < 0.03;脂肪热量减少1.7%,p = 0.07),饮食行为表现也有所改善(F = 14.2,P = 0.004)。家长示范作用的改善在统计学上不显著。
H5LF是一项有效的干预措施,适合全国2000多个“家长即教师”服务点采用,有可能影响全国非裔美籍父母的饮食摄入。
