Background: Anxiety disorders are common among adolescents. In high-income countries, anxiety is a known contributor to truancy and school refusal, but this association has been understudied in low- and middle-income countries (LMICs).

Methods: We used complex samples analysis to examine the association between self-reported worry-induced insomnia (an indicator of anxiety) and unauthorized school absenteeism among 268,142 adolescents from 69 LMICs that participated in the Global School-based Student Health Survey (GSHS).

Purpose: High rates of adolescent physical inactivity and sedentary behavior have been reported worldwide, but the combined prevalence of languorous behavior (physical inactivity and/or sedentary behavior) may more accurately reflect just how few adolescents meet World Health Organization recommendations.

Methods: We analyzed nationally representative data from 325,219 students in 80 countries that participated in the Global School-based Student Health Survey between 2009 and 2018. Students were classified as physically inactive if they reported engaging in moderate or vigorous physical activity less than 60 minutes daily.

Women of reproductive age are particularly at risk of obesity because of excessive gestational weight gain (GWG) and postpartum weight retention, resulting in poor health outcomes for both mothers and infants. The purpose of this qualitative study was to examine perceptions and barriers to GWG among low-income women in the WIC program to inform the development of an intervention study. Eleven focus groups were conducted and stratified by ethnicity, and each group included women of varying age, parity, and prepregnancy BMI ranges.

In part, this is because of a lack of appropriate tools to measure this complex phenomenon. This study was to validate the Educational Stress Scale for Adolescents (ESSA), developed and tested in China, with the aim of fostering further research in Asia.

Childhood obesity is a growing problem in the United States. Parental perception of their children's weight status is a key factor that needs to be considered when developing prevention programs for preschool children. Using a randomly selected sample of participants of Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) in Los Angeles County, we assessed accuracy of maternal perceptions of their children's weight status by comparing children's weight classification to the mothers' response to the question "Do you consider your child to be overweight, underweight or about right weight for (his) (her) height?" Additionally, we identified possible predictors of accurate maternal perception of their children's weight status by conducting a logistic regression model with child's gender, child's birth weight, maternal age, maternal BMI, maternal education, maternal acculturation level, and maternal language preference as potential predictors.
