STEPwise approach to chronic disease risk factor surveillance (STEPS)
Introduction
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 chronic disease risk factor surveillance provides an entry point for low and middle income countries to get started on chronic disease surveillance activities. It is also designed to help countries build and strengthen their capacity to conduct surveillance.
Design
The STEPS Instrument covers three different levels of "steps" of risk factor assessment. These steps are:
- Questionnaire
- Physical measurements
- Biochemical measurements
