本研究通过城市化水平考察了加州学校营养政策与儿童超重/肥胖人口水平趋势之间的关系。方法：我们使用中断时间序列与2002年至2010年期间在加州公立学校就读的非裔美国人、拉丁裔、亚裔和白人七年级学生的Fitnessgram超重/肥胖数据。我们使用多水平逻辑回归模型来检验加州连续学校营养政策对超重/肥胖患病率的影响，按性别分层，并根据学区、学校和学生水平的特征进行调整。结果：研究初期，农村地区和第二城市（即人口密度低于城市地区的人口中心）的患病率相对较低，但在2002-2004年急剧上升，导致超重/肥胖患病率高于郊区。有证据表明，除城市地区的女孩和二线城市的男孩外，大多数地区的政策都对超重/肥胖产生了有益的影响。有利变化的证据在农村地区上学的儿童以及郊区和城市地区的男孩中最为明显。即使我们考虑了种族/民族构成、学校和学校社区的社会经济特征、学校规模、儿童种族/民族、年龄和学生健康水平的差异，这些结果仍然存在。结论：尽管有证据表明有利的政策影响，儿童肥胖患病率仍然很高，特别是在加州的城市地区。建议采取额外的政策和环境干预措施，以解决每个地区特有的致肥风险因素。
Introduction: This study examined the association between California school nutrition policies and population-level trends in childhood overweight/obesity by levels of urbanicity. Methods: We used interrupted time series with Fitnessgram data on overweight/obesity from the period 2002 to 2010 pertaining to African American, Latino, Asian, and White students in seventh grades who attended California public schools. We used multilevel logistic regression models to examine the impact of the introduction of successive California school nutrition policies on overweight/obesity prevalence, stratified by gender and adjusted for school district-, school-, and student-level characteristics. Results: At the start of the study period, rural areas and second cities (i.e., population centers with lower population densities than urban areas) had relatively low prevalence, but experienced sharp increases in 2002–2004, leading to higher prevalence of overweight/obesity than suburban areas. There was evidence of beneficial policy influences on overweight/obesity in most areas, except for girls in urban areas and boys in second cities. The evidence of beneficial changes was strongest among children attending schools located in rural areas, and boys in suburban and urban areas. These results persisted even after we accounted for differences in racial/ethnic compositions, socioeconomic characteristics of the schools and school neighborhoods, and school sizes, as well as child-level race/ethnicity, age, and student fitness levels. Conclusion: Despite evidence of beneficial policy impact, childhood obesity prevalence remains high, especially in urban areas in California. Additional policies and environmental interventions are recommended to address obesogenic risk factors unique to each area.
