研究表明，含糖饮料中过多的热量与青少年体重增加有关。然而，人们对含糖饮料消费标准的认知还很有限。这项研究调查了对同龄人含糖饮料消费规范的误解程度以及感知的同龄人规范与个人自我报告的消费量之间的关联。 2008 年 11 月至 2009 年 5 月期间，对八所学校的 3,831 名 6 至 12 年级学生完成了匿名横断面调查，将学生对其所在学校（学校年级组）每日含糖饮料消费标准的个人看法与每个学校年级组每日含糖饮料消费量的自我报告汇总进行了比较。个人报告中的每日含糖饮料消费量中位数为：29 个学校年级组中有 24 个为 1 种饮料，4 个学校年级组为 2 种饮料，1 个学校年级组为 3 种饮料。 76% 的学生高估了学校年级组的每日标准，其中 24% 的学生认为标准是每天至少喝三杯或更多。固定效应多元回归分析表明，与每个学校年级组估计的实际含糖饮料消费标准相比，同龄人感知的含糖饮料消费标准与个人消费的正相关性要大得多。对同龄人含糖饮料消费标准的误解普遍存在，并且与不健康的含糖饮料消费行为有关。这些误解可能会导致卡路里摄入过多，从而可能导致青少年肥胖。未来的研究应该评估其他学校人群中含糖饮料消费误解的普遍性以及这些误解的原因和后果。卫生专业人员可能希望考虑规范性反馈干预措施如何可能减少消费。 J Am 饮食协会。 2010；110：1916-1921。
Research has shown that excess calories from sugar-sweetened beverages are associated with weight gain among youth. There is limited knowledge, however, regarding perception of sugar-sweetened beverage consumption norms. This study examined the extent of misperception about peer sugar-sweetened beverage consumption norms and the association of perceived peer norms with personal self-reported consumption. Among 3,831 6th- to 12th-grade students in eight schools who completed anonymous cross-sectional surveys between November 2008 and May 2009, students' personal perception of the daily sugar-sweetened beverage consumption norm in their school within their grade (School Grade group) was compared with aggregate self-reports of daily sugar-sweetened beverage consumption for each School Grade group. The median daily sugar-sweetened beverage consumption from personal reports was one beverage in 24 of 29 School Grade groups, two beverages in four School Grade groups, and three beverages in one School Grade group. Seventy-six percent of students overestimated the daily norm in their School Grade group, with 24% perceiving the norm to be at least three beverages or more per day. Fixed-effects multiple regression analysis showed that the perceived peer sugar-sweetened beverage consumption norm was much more positively associated with personal consumption than was the estimated actual sugar-sweetened beverage consumption norm per School Grade group. Misperceptions of peer sugar-sweetened beverage consumption norms were pervasive and associated with unhealthy sugar-sweetened beverage consumption behavior. These misperceptions may contribute to intake of excess calories, potentially contributing to adolescent obesity. Future research should assess the pervasiveness of sugar-sweetened beverage consumption misperceptions in other school populations as well as causes and consequences of these misperceptions. Health professionals may wish to consider how normative feedback interventions could potentially reduce consumption. J Am Diet Assoc. 2010;110:1916-1921.
