Individual-participant data analysis of the Global School-Based Student Health Survey and Health Behaviour in School-Aged Children surveys in 57 LMICs between 2003-2013.
We used the most recent Global School-Based Student Health Surveys (GSHS) and Health Behaviour in School-Aged Children (HSBC) surveys, with data available on height and weight. The GSHS is a World Health Organisation (WHO) initiative, designed to assess health behaviours of adolescents through cross-sectional school-based surveys, across several countries using similar standardised procedures. The HSBC study are WHO sponsored cross-sectional school-based surveys that uses similar standardised procedures to the GSHS to examine the physical and mental health of adolescents in the WHO European Region and North America.
