title: Use of calorie information at fast food and chain restaurants among US youth aged 9-18 years, 2010.
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  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.
