The STEPS survey of noncommunicable disease (NCD) risk factors in Kenya was carried out from April to June 2015. Step 1, Step 2 and step 3 were carried out together with the two optional modules on Oral Health and on Violence and Injuries. Socio demographic and behavioural information were collected in Step 1. Physical measurements such as height, weight and blood pressure were collected in Step 2. Biochemical measurements were collected to assess blood glucose and cholesterol levels in Step 3. The survey was a population-based survey of adults age 18-69 years. A multi-cluster random sample design was used to produce representative data for that age range in Kenya. A total of 6000 adults participated in the survey.
