To examine whether youth use calorie information when it is available at fast food/chain restaurants and what factors are associated with using this information to make their food selection.
A cross-sectional analysis was conducted on a sample of 721 youth (9-18 years) using the 2010 YouthStyles and HealthStyles surveys. The outcome measure was reported use of calorie information at fast food/chain restaurants. Multivariable logistic regression was used to examine the associations between sociodemographic variables and the use of calorie information at fast food/chain restaurants.
Of those who visited fast food/chain restaurants, 42.4% reported using calorie information at least sometimes. Girls were more likely than boys (adjusted odds ratio (aOR) = 1.8, 95% confidence interval (CI) = 1.2-2.5) and youth who were obese were more likely than those at a healthy weight (aOR = 1.7, 95% CI = 1.04-2.9) to use calorie information, and youth eating at a fast food/chain restaurant twice a week or more versus once a week or less were half as likely to report using calorie information (aOR = 0.5, 95% CI = 0.4-0.8).
Public health education efforts can benefit from research to determine how to increase usage among youth so that their food choices are appropriate for their caloric needs.
研究青少年在快餐/连锁餐厅有卡路里信息时是否会使用，以及哪些因素与利用这些信息进行食物选择相关。
使用2010年青少年生活方式和健康方式调查对721名青少年（9 - 18岁）样本进行横断面分析。结果指标是报告在快餐/连锁餐厅使用卡路里信息的情况。采用多变量逻辑回归分析社会人口统计学变量与在快餐/连锁餐厅使用卡路里信息之间的关联。
在去过快餐/连锁餐厅的人群中，42.4%报告至少有时会使用卡路里信息。女孩比男孩更有可能使用（调整后的优势比（aOR）= 1.8，95%置信区间（CI）= 1.2 - 2.5），肥胖青少年比体重正常的青少年更有可能使用（aOR = 1.7，95% CI = 1.04 - 2.9），每周在快餐/连锁餐厅就餐两次或更多次的青少年与每周就餐一次或更少次的青少年相比，报告使用卡路里信息的可能性减半（aOR = 0.5，95% CI = 0.4 - 0.8）。
公共卫生教育工作可受益于相关研究，以确定如何提高青少年对卡路里信息的使用率，使他们的食物选择符合其热量需求。
