STEPwise approach to noncommunicable disease risk factor surveillance (STEPS)

The STEPS approach focuses on obtaining core data on the established risk factors that determine the major disease burden. It is sufficiently flexible to allow each country to expand on the core variables and risk factors, and to incorporate optional modules related to local or regional interests.

Purpose:

The WHO STEPwise approach to noncommunicable disease (NCD) risk factor surveillance is designed to help countries build and strengthen their surveillance capacity.

Design:

The STEPS Instrument covers three different levels of “steps” of risk factor assessment. These steps are:
1. Questionnaire
2. Physical measurements
3. Biochemical measurements
