John NkonyanaDirector Disease Control
Discription
• The STEPS survey of chronic disease risk factors was carried out from April to May 2012.
• Lesotho carried out Step 1, Step 2 and Step 3.
Methodology
Step 1: Socio demographic and behavioural information.
Step 2: Physical measurements such as height, weight and blood pressure.
Step 3: Biochemical measurements were collected to assess blood glucose and cholesterol levels
Methodology
• The STEPS survey was a population-based survey of adults aged 25-64.
• A multi-stage cluster sample design was used to produce representative data for that age range.
• A total of 2310 adults participated in the survey. • The overall response rate was 80%.
