Two main scopes will be included in the survey. Scopes in the 2012 survey will be repeated and an additional scope on oral health will be included 1. The Global School Health Survey (GSHS) GSHS surveillance project designed by the World Health Organisation to help countries to measure and assess the behavioural risk factors and protective factors in 10 key areas among young people aged 13 to 17 years (form 1 to 5). The GSHS is a relatively low-cost school-based survey which uses a self-administered questionnaire to obtain data on young people's health behaviour and protective factors related to the leading causes of morbidity and mortality among children and adults worldwide. As in the previous survey, additional modules on mental health to cover depression, anxiety and stress will be included the survey. 2. National School-Based Nutrition Survey The National School-Based Nutrition Survey consisted of a few nutrition-related components, including nutritional status, meal pattern, physical activity, behaviour modification, supplement intake, food frequency intake, and 24-hour dietary recall. The survey will be targeted at students aged 10 to 17 years (standard 4 to form 5).
