我们研究了与社会经济地位较低的学生较少的学校周围区域相比，社会经济地位较低的学生较多的学校周围区域是否有更多的食品/饮料广告总量和/或营养成分较差的广告。 2012 年，美国 47 所初高中半英里半径范围内的所有户外食品/饮料广告都得到了客观记录，并进行了营养成分编码。计算广告总数以及广告中描述的食品和饮料项目的常量营养素和微量营养素含量（总热量、脂肪（g）、蛋白质（g）、碳水化合物（g）、糖（g）和钠（mg））。总共记录了 9132 个独特的广告，其中 3153 个广告展示了可以编码营养成分的食品和饮料。与位于社会经济地位较高地区的学校相比，位于社会经济地位较低地区（≥60%的学生接受免费/减价午餐）的学校，展示可对营养成分进行编码的食品和饮料的广告明显更多（z = 2.01，p = 0.04），以及含有更多钠的广告（z = 2.20，p = 0.03）。卡路里、脂肪、蛋白质、碳水化合物或糖含量没有差异。有必要制定政策来减少户外食品和饮料广告的流行。
We examined if areas around schools with more students of lower socioeconomic status (SES) have more total food/beverage advertisements and/or more advertisements with poorer nutritional content as compared to areas around schools with fewer students with lower SES. All outdoor food/beverage advertisements within a half-mile radius of 47 middle and high schools in the United States were objectively documented in 2012 and coded for nutritional content. The total number of advertisements and the macronutrient and micronutrient contents (total calories, fat (g), protein (g), carbohydrate (g), sugar (g), and sodium (mg)) of food and beverage items depicted in the advertisements were calculated. In total, 9132 unique advertisements were recorded, with 3153 ads displaying food and beverages that could be coded for nutrient content. Schools located in areas of lower SES (≥60% students receiving free/reduced-price lunch) had significantly more advertisements displaying food and beverages that could be coded for nutrient content (z = 2.01, p = 0.04), as well as advertisements that contained more sodium (z = 2.20, p = 0.03), as compared to schools located in areas of higher SES. There were no differences in calorie, fat, protein, carbohydrate, or sugar content. Policies to reduce the prevalence of outdoor food and beverage advertising are warranted.
