Given the importance of developing healthy eating patterns during early childhood, policies to improve the elementary school food and beverage environments are critical.
To examine the association between district and state policy and/or law requirements regarding competitive food and beverages and public elementary school availability of foods and beverages high in fats, sugars, and/or sodium.
Multivariate, pooled, cross-sectional analysis of data gathered annually during elementary school years 2008-2009 through 2010-2011 in the United States.
Survey respondents at 1814 elementary schools (1485 unique) in 957 districts in 45 states (food analysis) and 1830 elementary schools (1497 unique) in 962 districts and 45 states (beverage analysis). EXPOSURES Competitive food and beverage policy restrictions at the state and/or district levels.
Competitive food and beverage availability. RESULTS Sweets were 11.2 percentage points less likely to be available (32.3% vs 43.5%) when both the district and state limited sugar content, respectively. Regular-fat baked goods were less available when the state law, alone and in combination with district policy, limited fat content. Regular-fat ice cream was less available when any policy (district, state law, or both) limited competitive food fat content. Sugar-sweetened beverages were 9.5 percentage points less likely to be available when prohibited by district policy (3.6% vs 13.1%). Higher-fat milks (2% or whole milk) were less available when prohibited by district policy or state law, with either jurisdiction's policy or law associated with an approximately 15 percentage point reduction in availability.
Both district and state policies and/or laws have the potential to reduce in-school availability of high-sugar, high-fat foods and beverages. Given the need to reduce empty calories in children's diets, governmental policies at all levels may be an effective tool.
鉴于在儿童早期培养健康饮食习惯的重要性,改善小学食品和饮料环境的政策至关重要。
研究有关竞争性食品和饮料的地区和州政策和/或法律要求与公立小学高脂肪、高糖和/或高钠食品和饮料供应之间的关联。
在美国,2008-2009 年至 2010-2011 年小学学年期间,每年对数据进行多元、 pooled、横断面分析。
在 45 个州的 957 个地区的 1814 所小学(1485 个独特学校)(食品分析)和 45 个州的 962 个地区和 1830 所小学(1497 个独特学校)(饮料分析)的调查受访者。
州和/或地区层面的竞争性食品和饮料政策限制。
竞争性食品和饮料供应情况。
当地区和州分别限制糖含量时,含糖量分别为 32.3%和 43.5%,甜食的供应率降低了 11.2 个百分点。当州法律单独或与地区政策结合限制脂肪含量时,常规脂肪烘焙食品的供应减少。当任何政策(地区、州法律或两者兼有)限制竞争性食品脂肪含量时,常规脂肪冰淇淋的供应减少。当地区政策禁止含糖饮料(3.6%对 13.1%)时,含糖饮料的供应率降低了 9.5 个百分点。当地区政策或州法律禁止高乳脂牛奶(2%或全脂牛奶)时,供应率较低,而任何司法管辖区的政策或法律都与供应率降低约 15 个百分点有关。
地区和州的政策和/或法律都有可能减少校内高糖、高脂肪食品和饮料的供应。鉴于需要减少儿童饮食中的空卡路里,各级政府政策可能是一种有效的工具。
