本研究的目的是评估一个新的学校为基础的食品合作社计划，明亮的咬（BB），以增加水果和蔬菜的摄入量，低收入的一年级学生和他们的父母和家庭营养环境的有效性。这是一项非随机对照比较有效性试验（2013-2015）。六所学校收到BB（n= 407亲子配对）;六所比较学校在德克萨斯州休斯顿实施了协调的学校健康计划（n = 310亲子配对），2013-2015。Brighter Bites（BB）是一个为期16周的学校食品合作社，包括每周分发新鲜农产品（50份）;在学校和家长中进行营养教育;每周品尝食谱。测量方法包括家长报告的家庭营养环境调查，以及家长和孩子的食物频率问卷。干预效果采用多变量分析。在基线时，样本为71%的西班牙裔，24%的非洲裔美国人; 43%的一年级学生超重/肥胖。接受BB的儿童水果摄入量（P = 0.046）、蔬菜摄入量（P = 0.049）显著增加，添加糖摄入量减少（P = 0.014）。在父母中，水果消费量显著增加（P = 0.032）;蔬菜摄入量从基线增加到中点，但干预后没有增加。在BB家庭中，家庭环境有了显著改善，包括理解和使用营养成分标签来购买食物（P < 0.05），烹调次数（P = 0.007），关于吃家庭餐的规则和做法（P= 0.022），食用水果（P= 0.005）蔬菜（P = 0.028）在进餐时，限制份量因此，以学校为基础的食物合作模式在改善低收入家庭的饮食习惯和家庭营养环境方面具有良好的效果。(C)2016 Elsevier Inc.

The purpose of this study was to evaluate the effectiveness of a new school-based food co-op program, Brighter Bites (BB), to increase fruit and vegetable intake, and home nutrition environment among low-income 1st graders and their parents. This was a non-randomized controlled comparative effectiveness trial (2013-2015). Six schools received BB (n= 407 parent-child dyads); six comparison schools implemented a coordinated school health program (n = 310 parent-child dyads) in Houston, Texas, 2013-2015. Brighter Bites (BB) is a 16-week school-based food co-op comprising weekly distribution of fresh produce (50 servings); nutrition education in schools and for parents; andweekly recipe tastings. Measurements included parent-reported home nutrition environment surveys, and food frequency questionnaires for parent and child. Intervention effects were examined using multivariate analyses. At baseline, the sample was 71% Hispanic, 24% African American; 43% of 1st graders were overweight/ obese. Children receiving BB had significant increases in intake of fruit servings (P = 0.046), vegetable servings (P = 0.049), and decreased intake of added sugars (P = 0.014). Among parents, there were significant increases in fruit consumed (P = 0.032); vegetable intake increased baseline to midpoint but not post-intervention. Among BB families, therewere significant improvements in the home environment including understanding and usage of nutrition facts labels to make food purchases (P < 0.05), frequency of cooking (P = 0.007), rules and practices regarding eating familymeals (P= 0.022), serving fruits (P= 0.005) and vegetables (P = 0.028) at meals, and limiting portion sizes (P= 0.016).In conclusion, a school-based food co-op model shows promising results in improving dietary habits and home nutrition environment among low-income families.
