Background: The school environment has the potential to influence student body mass index (BMI) through programs and policies. Our objective was to examine the effect of modifying obesity-related school policies and programs on youths' BMI trajectories. Methods: Obesity-related school policies and programs related to physical activity and healthy…

Background: We explored the relationship between body mass index-for-age percentile, body image distortion, and unnecessary weight loss efforts in Korean adolescent girls who are underweight and normal weight and examined the mediating effect of body image distortion on weight loss efforts. Methods: This study used data from the 2013 Korea Youth…

Background: Several studies have used latent class analyses to explore obesogenic behaviors and substance use in adolescents independently. We explored a variety of health risks jointly to identify distinct patterns of risk behaviors among adolescents. Methods: Latent class models were estimated using Youth Risk Behavior Surveillance System…

Background: Adolescent overweight and obesity are serious health risks, with prevalence varying by sociodemographic group. Studies link children's weight status and sex/race-ethnic differences with meeting recommendations for physical activity and diet. But, research examining the intersection of sociodemographic characteristics, behavior, and…

Many Orleans Parish public schools were provided with salad bars (SBs) to augment school…

Background: Previous research has reported mixed results on the association between body weight measures (ie, perception of weight and weight loss goal) and cigarette smoking prevalence--and how these associations vary by sex and race. This longitudinal study assessed the relationship between these 2 body weight measures and smoking prevalence by…

Background: Research on physical activity breaks and facilities (indoor and outdoor) in secondary schools is relatively limited. Methods: School administrators and students in nationally representative samples of 8th (middle school) and 10th/12th grade (high school) students were surveyed annually from 2008-2009 to 2011-2012.
