To evaluate the impact of the University of Kentucky's Healthy Choices for Every Body (HCEB) adult nutrition education curriculum on participants' food resource management (FRM) skills and food safety practices.
A quasi-experimental design was employed using propensity score matching to pair 8 intervention counties with 8 comparison counties. Independent-samples t tests and ANCOVA models compared gains in FRM skills and food safety practices between the intervention and comparison groups (n = 413 and 113, respectively).
Propensity score matching analysis showed a statistical balance and similarities between the comparison and intervention groups. Food resource management and food safety gain scores were statistically significantly higher for the intervention group (P < .001), with large effect sizes (d = 0.9) for both variables. The group differences persisted even after controlling for race and age in the ANCOVA models.
The HCEB curriculum was effective in improving the FRM skills and food safety practices of participants.
评估肯塔基大学健康选择计划(HCEB)成人营养教育课程对参与者食物资源管理(FRM)技能和食品安全实践的影响。
采用倾向评分匹配的准实验设计,将 8 个干预县与 8 个对照县进行配对。独立样本 t 检验和协方差分析模型比较了干预组和对照组在 FRM 技能和食品安全实践方面的收益(分别为 n=413 和 113)。
倾向评分匹配分析显示,对照组和干预组之间存在统计学上的平衡和相似性。干预组的食物资源管理和食品安全收益得分显著更高(P<0.001),两个变量的效应量均较大(d=0.9)。即使在协方差分析模型中控制了种族和年龄因素,组间差异仍然存在。
HCEB 课程在提高参与者的 FRM 技能和食品安全实践方面是有效的。
