Other Household Survey [hh/oth]
This is the second STEPS conducted by Viet Nam.
STEPS is a household-based survey to obtain core data on the established risk factors that determine the major burden of NCDs.

Version
Public-use dataset
Scope
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, history of raised total cholesterol, history of cardiovascular diseases, lifestyle advice, and cervical cancer screening. Additionally, the following measures were taken: blood pressure, height, weight, waist circumference, hip circumference, heart rate, fasting blood glucose, total cholesterol and triglycerides.

Sampling
At the same time of the STEPS survey, MOH also conducted the Global Adult Tobacco Survey (GATS) at the same scale, location, and with the same study subjects (>15 years for GATS and 18-69 for STEPS) to save time and resources for these two surveys. A multi-stage cluster sample of households was drawn. One individual within the age range of the survey was selected per household. Further information can be found on page 6-7 of the report.
The total subjects aged 18-69 selected and participated in STEPS survey were 3856. Of them, 3758 subjects participated in STEP 1 (response rate: 97.4%) and 3080 subjects participated in both STEP 1, 2 and 3 (79.8%).
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. Additionally, some countries perform subsampling for Step 2 and/or Step 3. When no subsampling is done and response rates do not differ across Steps of the survey, the 3 weight variables will be the same.
