Coverage
National
Adults aged 18-69 years.
Sampling
A multi-stage cluster sample of households. One individual within the age range of the survey was selected per household. See p. 28 of report for further detail.
A total of 6267 adults participated in the survey. The overall (step 1) response rate was 81%, step 2 response rate was 73% and step 3 response rate was 61%.
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.
