To evaluate dose-response associations between misperceived weight and 32 health risk behaviors in a nationally representative sample of US adolescents.
Participants included 13,864 US high school students in the 2011 Youth Risk Behavior Survey. Comparing the degree of agreement between perceived and reported actual weight, weight misperception was determined as 5 categories. Multivariable-adjusted logistic regression analyses evaluated associations of weight misperception with 32 health risk behaviors.
Both underestimated and overestimated weight were statistically significantly associated with all 32 health risk behaviors in a dose-response manner after adjustment for age, sex and race/ethnicity, where greater weight misperception was associated with higher engagement in health risk behaviors.
Understanding potential impacts of weight misperception on health risk behaviors could improve interventions that encourage healthy weight perception and attainment for adolescents.
在美国青少年的全国代表性样本中，评估体重误判与32种健康风险行为之间的剂量反应关联。
参与者包括2011年青少年风险行为调查中的13864名美国高中生。通过比较感知体重与报告的实际体重之间的一致程度，将体重误判分为5类。多变量调整逻辑回归分析评估体重误判与32种健康风险行为之间的关联。
在对年龄、性别和种族/民族进行调整后，低估和高估体重均与所有32种健康风险行为在剂量反应关系上具有统计学显著关联，体重误判程度越大，与健康风险行为的参与度越高相关。
了解体重误判对健康风险行为的潜在影响，可能会改善鼓励青少年形成健康体重认知并实现健康体重的干预措施。
