Surveillance Country profiles


icon Risk factors ( 46 Files )

The risk factors included are those that make the greatest contribution to mortality and morbidity from cardiovascular disease, can be changed through primary intervention, and are easily measured in populations. These risk factors are: tobacco and alcohol use, patterns of physical inactivity, low fruit/vegetable intake, overweight/obesity, blood pressure, cholesterol

icon Global School-based Student Health Survey (GSHS) ( 12 Files )

The GSHS was developed by the World Health Organization (WHO) in collaboration with United Nations' UNICEF, UNESCO, and UNAIDS; and with technical assistance from CDC. GSHS is a school-based survey conducted primarily among students aged 13–15 years.

The purpose of the GSHS is to provide data on health Behaviors and protective factors among students such as alcohol and other drug use; sexual behaviors that contribute to HIV infection, other STI, and unintended pregnancy; unintentional injuries and violence; hygiene; dietary behaviors and overweight; physical activity; tobacco use; mental health; and protective factors to :

  • Help countries develop priorities, establish programs, and advocate for resources for school health and youth health programs and policies;
  • Allow international agencies, countries, and others to make comparisons across countries regarding the prevalence of health behaviors and protective factors; and
  • Establish trends in the prevalence of health behaviors and protective factors by country for use in evaluation of school health and youth health promotion

icon STEPS survey on Noncommunicable Disease Risk Factors ( 20 Files )

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).
