The STEPS Noncommunicable Disease Risk Factors Survey uses a survey methodology developed by the World Health Organization (WHO) to help countries establish noncommunicable disease surveillance systems. The methodology prescribes three steps—questionnaire, physical measurements, and biochemical measurements. Core topics covered by most surveys are demographics, health status, and health behaviors. These provide data on socioeconomic risk factors and metabolic, nutritional, and lifestyle risk factors. Details may differ from country to country and from year to year.

The Swaziland STEPS Noncommunicable Disease Risk Factors Survey 2014 included the following optional modules in their data collection: oral health, mental health, violence and injury, and tobacco policy. A total of 3,534 residents ages 15-69 responded to the Step I questionnaire.
