To examine changes in prevalence of obesity and target health behaviors (fruit, vegetable, and beverage consumption; physical activity; screen time; sleep duration) among students from communities that participated in the Massachusetts Childhood Obesity Research Demonstration (MA-CORD) project compared to controls.
MA-CORD was implemented in two low-income communities. School-level prevalence of obesity among students in first, fourth, and seventh grades was calculated for the intervention communities and nine matched control communities pre and post intervention. Fourth- and seventh-grade students' self-reported health behaviors were measured in intervention communities at baseline and post intervention.
Among seventh-graders (the student group with greatest intervention exposure), a statistically significant decrease in prevalence of obesity from baseline to post intervention in Community 2 (-2.68%, P = 0.049) and a similar but nonsignificant decrease in Community 1 (-2.24%, P = 0.099) was observed. Fourth- and seventh-grade students in both communities were more likely to meet behavioral targets post intervention for sugar-sweetened beverages (both communities: P < 0.0001) and water (Community 1: P < 0.01; Community 2: P = 0.04) and in Community 2 for screen time (P < 0.01).
This multisector intervention was associated with a modest reduction in obesity prevalence among seventh-graders in one community compared to controls, along with improvements in behavioral targets.
研究参与马萨诸塞州儿童肥胖研究示范项目（MA-CORD）的社区学生与对照组相比，肥胖患病率及目标健康行为（水果、蔬菜和饮料消费；体育活动；屏幕使用时间；睡眠时间）的变化情况。
MA-CORD项目在两个低收入社区实施。计算干预社区以及九个匹配的对照社区在干预前后一、四、七年级学生的学校层面肥胖患病率。在干预社区，对四年级和七年级学生在基线和干预后的自我报告健康行为进行测量。
在七年级学生中（该学生群体受干预影响最大），观察到社区2从基线到干预后肥胖患病率有统计学意义的下降（-2.68%，P = 0.049），社区1有类似但无统计学意义的下降（-2.24%，P = 0.099）。两个社区的四年级和七年级学生在干预后更有可能达到含糖饮料（两个社区：P < 0.0001）和水（社区1：P < 0.01；社区2：P = 0.04）的行为目标，在社区2屏幕使用时间方面也达到了目标（P < 0.01）。
与对照组相比，这种多部门干预与一个社区七年级学生的肥胖患病率适度降低以及行为目标的改善相关。
