Rational planning of community policies and programs (CPPs) to prevent obesity requires an understanding of CPP objectives associated with dietary behaviours.
The objective of the study is to identify objectives of CPPs associated with healthful dietary behaviours.
An observational study identified 4026 nutrition CPPs occurring in 130 communities in the prior 6 years. Dietary intakes of fruits and vegetables, added sugar and sugar-sweetened beverages, among others, were reported among 5138 children 4-15 years of age from the communities, using a Dietary Screener Questionnaire with children age 9 years and older (parent assisted) or parent proxies for younger children. CPPs were documented through key informant interviews and characterized by their intensity, count, and objectives including target dietary behaviour and food environment change strategy. Associations between dietary intakes and CPP objectives were assessed using hierarchical statistical models.
CPPs with the highest intensity scores that targeted fast food or fat intake or provided smaller portions were associated with greater fruit and vegetable intake (0.21, 0.19, 0.23 cup equivalents/day respectively with p values <0.01, 0.04, 0.03). CPPs with the highest intensity scores that restricted the availability of less healthful foods were associated with lower child intakes of total added sugar (-1.08 tsp/day, p < 0.01) and sugar from sugar-sweetened beverages (-1.63 tsp/day, p = 0.04). Similar associations were observed between CPP count and dietary outcomes. No other significant associations were found between CPP target behaviours or environmental strategies and dietary intakes/behaviours.
CPPs that targeted decreases in intakes of less healthful foods and/or aimed to modify the availability of less healthful foods and portions were associated with healthier child dietary behaviours.
合理规划社区预防肥胖的政策和项目(CPPs)需要了解与饮食行为相关的CPP目标。
本研究的目的是确定与健康饮食行为相关的CPP目标。
一项观察性研究在之前6年中识别出130个社区开展的4026项营养CPPs。使用饮食筛查问卷,对来自这些社区的5138名4至15岁儿童的水果和蔬菜、添加糖和含糖饮料等的饮食摄入量进行了报告,9岁及以上儿童由家长协助填写问卷,年幼儿童则由家长代填。通过关键 informant访谈记录CPPs,并根据其强度、数量和目标进行特征描述,包括目标饮食行为和食物环境改变策略。使用分层统计模型评估饮食摄入量与CPP目标之间的关联。
针对快餐或脂肪摄入量或提供较小份量的强度得分最高的CPPs与更高的水果和蔬菜摄入量相关(分别为0.21、0.19、0.23杯当量/天,p值<0.01、0.04、0.03)。限制不健康食品供应的强度得分最高的CPPs与儿童总添加糖摄入量较低(-1.08茶匙/天,p<0.01)和含糖饮料中的糖摄入量较低(-1.63茶匙/天,p=0.04)相关。在CPP数量与饮食结果之间也观察到类似的关联。在CPP目标行为或环境策略与饮食摄入量/行为之间未发现其他显著关联。
旨在减少不健康食品摄入量和/或旨在改变不健康食品及份量供应情况的CPPs与更健康的儿童饮食行为相关。
