Effective strategies for the prevention and control of NCDs require specific data. Good quality, reliable, standardized and sustainable data help countries set their priorities and develop targeted interventions to reverse the NCD epidemic. Surveillance is thus a fundamental tool in WHO’s work to prevent and control NCDs.
WHO STEPwise approach
The WHO STEPwise approach to surveillance of NCD risk factors (STEPS) is the recommended tool for surveillance of chronic diseases and their risk factors. STEPS was developed by WHO as part of a global surveillance strategy, in response to the growing need for country-level trends in NCDs.
STEPS uses a standard survey instrument and a methodology that can be adapted to different country resource settings and helps to build country capacity. STEPS provides information not only for monitoring NCD trends within countries, but for cross-country comparisons as well, using the same standardized questions and protocols across all countries.
