R code and STATA DO files written and used to construct an individual-level analytical dataset from two consecutive nationally representative surveys conducted in Viet Nam in 2007 and 2017. The source datasets can be requested from the Viet Nam National Lung hospital by e-mailing bvptw@bvptw.org.
Code and accompanying files are made available to support a paper, titled “Social determinants of the changing tuberculosis prevalence in Viet Nam: analysis of population-level cross-sectional studies” (This is in-development at the time of writing).
Cross-sectional surveys using multistage cluster sampling based on the estimated prevalence of TB in the country at the time of the study. One survey was conducted in 2007 and another in 2017. Each cluster was a district. Individuals living in enumerated households were eligible for inclusion in the study if >15 and lived in the household for >3 months (2007 survey) but >2 weeks in the 2017 survey. Participants were screened for TB based on self-reported symptoms and chest radiograph results. Tuberculosis case definition was having had a smear test and at least one positive LJ culture.
An asset index was constructed using principal component analysis (PCA) of size variables (1) the presence of clay floors, (2) wood as fuel for cooking, (3) ownership of a stereo system, (4) television, (5) motorbike, or (6) car. Using the index, households were divided into four groups based on their relative wealth. “Neighbourhood” provincial poverty variables were generated by combining clusters into provinces and imputing provincial poverty values based on data from the World Bank.
