    Abstract

    The STEPS survey of chronic disease risk factors in Malawi was carried out from July 2009 to September 2009. Malawi carried out Step 1, Step 2 and Step 3. Socio demographic and behavioural information was 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 STEPS survey in Malawi 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 in Malawi. A total of 5,206 adults participated in the Malawi STEPS survey, of which 67.5% were female. The overall response rate was 95.5%

    Scope

    Notes

    The following topics were included in the survey: tobacco use, alcohol consumption, diet, physical activity, history of raised blood glucose, history of raised blood pressure and lifestyle advice. Additionally, the following measures were taken: blood pressure, height, weight, waist circumference, hip circumference, heart rate, fasting blood glucose and total cholesterol.

    Sampling

    Sampling Procedure

    A multi-stage cluster sampling design was used to produce a national representative sample. Participants were people aged 25-64 years. Data was collected in steps 1, 2 and 3 using personal digital assistants (PDAs). Socio demographic and behavioural information was collected in Step 1. Physical measurements such as height, weight, blood pressure and waist and hip circumference were collected in Step 2. Biochemical measurements were collected to assess total cholesterol levels and fasting blood glucose in Step 3. Data was weighed for age, gender and population size for Malawi and analysed using WHO STEPS Survey software.
    Response Rate

    Overall response rate: 95.5%
    Weighting

    Analysis weights were calculated by taking the inverse of the probability of selection of each participant. These weights were adjusted for differences in the age-sex composition of the sample population as compared to the target population.

    Different weight variables are available per Step:

    • wStep1 - for interview data

    • wStep2 - for physical measures

    • wStep3 - for biochemical measures

    This allows for differences in the weight calculation for each Step of the survey as the age-sex composition of the respondents to each Step can differ slightly due to refusal or drop out.
