To determine extent and factors associated with implementation of California's school nutrition standards 1 year after standards became active.
Information on competitive foods and beverages available in schools was collected from a representative sample of 56 public high schools in California. Adherence to nutrition standards was calculated for each item and summarized for each school by venue. The association between schools' sociodemographic characteristics and adherence to standards was determined by multivariate analysis.
The majority of schools were adhering to the required beverage standards. None of the schools selling competitive foods were 100% adherent to the food standards. Adherence to both standards tended to be highest in food service venues. In univariate analyses, percent nonwhite enrollment, population density, percent free/reduced-price (FRP) meal eligibility, and school size were significantly correlated with the beverage adherence rate. Percent nonwhite enrollment and population density remained significant in the multivariate regression model. Percent nonwhite enrollment and percent FRP meal eligibility were significantly correlated with the food adherence rate in univariate analysis, but neither remained significant in the multiple regression model.
California high schools are making progress toward implementation of the state nutrition standards. Beverage standards appear easier to achieve than nutrient-based food standards. Additional support is needed to provide schools with resources to implement and monitor these policies. Simpler standards and/or a reduction in the foods and beverages sold could better enable schools to achieve and monitor adherence.
确定加利福尼亚州学校营养标准实施一年后的实施程度及相关因素。
从加利福尼亚州56所公立高中的代表性样本中收集学校中可获得的竞争性食品和饮料的信息。计算每个项目对营养标准的遵守情况,并按场所对每所学校进行汇总。通过多变量分析确定学校的社会人口统计学特征与遵守标准之间的关联。
大多数学校遵守了规定的饮料标准。销售竞争性食品的学校中没有一所100%遵守食品标准。在食品服务场所,对这两项标准的遵守程度往往最高。在单变量分析中,非白人入学率、人口密度、免费/减价(FRP)餐资格百分比和学校规模与饮料遵守率显著相关。在多变量回归模型中,非白人入学率和人口密度仍然显著。在单变量分析中,非白人入学率和FRP餐资格百分比与食品遵守率显著相关,但在多元回归模型中均不显著。
加利福尼亚州的高中在实施州营养标准方面正在取得进展。饮料标准似乎比基于营养的食品标准更容易实现。需要额外的支持为学校提供实施和监督这些政策的资源。更简单的标准和/或减少销售的食品和饮料可以更好地使学校实现并监督遵守情况。
