• Conditions: Stunting; Thinness; Obese

• Registration Number: NCT03346473
• Lead Sponsor: University of Warwick

Brief Summary

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.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Prevalence of stunting	2003-2013	Trained survey staff measured the height of each student. Stunting was defined as height-for age \< 2 standard deviations below the WHO Child Growth Reference median.
Prevalence of overweight and obesity	2003-2013	Overweight was defined as BMI-for-age \> 1 standard deviation above the WHO Growth Reference median) and obesity was defined as \>2 standard deviations above the WHO Growth Reference median.
Prevalence of thinness	2003-2013	Trained survey staff measured the weight of each student. Thinness was defined as BMI-for-age \< 2 standard deviations below the WHO Growth Reference median. Body mass index \[BMI (weight in kilograms divided by height in meters squared)\] was calculated from height and weight.
