尽管有许多措施可以改善街角商店的健康食品供应，但很少有随机试验评估其效果。本研究评估，在一项随机对照试验中，第一代健康的角落商店干预对学生的食品和饮料购买超过2年的periods.MethodsParticipants（n= 767）的影响是四，五，六年级的学生。10所学校及其附近的街角商店（n= 24）被随机分配到健康的街角商店干预或仅评估对照组。拦截调查直接评估了学生在基线，1年和2年的街角商店购买的营养特征。学生的体重和身高进行了测量，在基线，1和2 years.ResultsThere是没有差异的能量含量每截距购买控制或干预学校在第1年（P= 0.12）或2（P= 0.58）。对照组和干预组学生的BMI评分无差异（第1年，P= 0. 83;第2年，P= 0. 05）。98)或肥胖患病率（第1年，P= 0.96;第2年，P= 0.58）。ConclusionsA健康的街角商店倡议并没有导致显着的变化，在街角商店购买的能量含量或在连续或分类的措施肥胖。这些数据将有助于为今后的干预提供信息。
ObjectiveAlthough many initiatives exist to improve the availability of healthy foods in corner stores, few randomized trials have assessed their effects. This study evaluated, in a randomized controlled trial, the effects of a first‐generation healthy corner store intervention on students' food and beverage purchases over a 2‐year period.MethodsParticipants (n= 767) were fourth‐, fifth‐, and sixth‐grade students. Ten schools and their nearby corner stores (n= 24) were randomly assigned to the healthy corner store intervention or an assessment‐only control. Intercept surveys directly assessed the nutritional characteristics of students' corner store purchases at baseline, 1 and 2 years. Students' weight and heights were measured at baseline, 1 and 2 years.ResultsThere were no differences in energy content per intercept purchased from control or intervention schools at year 1 (P= 0.12) or 2 (P= 0.58). There were no differences between control and intervention students in BMIzscore (year 1,P= 0.83; year 2,P= 0. 98) or obesity prevalence (year 1,P= 0.96; year 2,P= 0.58).ConclusionsA healthy corner store initiative did not result in significant changes in the energy content of corner store purchases or in continuous or categorical measures of obesity. These data will help to inform future interventions.
