Global School-based Student Health Survey (GSHS)

The Global school-based student health survey (GSHS) is a collaborative surveillance project designed to help countries measure and assess the behavioural risk factors and protective factors in 10 key areas among young people aged 13 to 17 years. 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.

STEPS survey on Noncommunicable Disease Risk Factors

STEP Survey - The WHO STEPwise approach to Surveillance (STEPS) of risk factors is a simple, standardized method for collecting, analysing and disseminating data for chronic disease risk factors in WHO member countries.By using the same standardized questions and protocols, all countries can use STEPS information not only for monitoring within-country trends, but also for making comparisons across countries. The approach encourages the collection of small amounts of useful information on a regular and continuing basis adopting a standard methodology to detect trends over time by age and sex.

STEPS risk factors is a sequential process, starting with gathering information on key risk factors by:

  • using a questionnaire (Step 1),
  • then moving to simple physical measurements (Step 2),
  • and only then recommending the collection of blood samples for biochemical assessment (Step 3).
