To study the association between TB and household expenditure in a nationwide TB prevalence survey in Viet Nam using nine household characteristics.
To assess the prevalence of TB in Viet Nam, a nationwide stratified cluster sample survey was conducted from 2006 to 2007. Nine household characteristics used in the second Viet Nam Living Standards Survey (VLSS) were scored per household. In the VLSS dataset, we regressed these nine characteristics against household expenditure per capita, and used the coefficients to predict household expenditure level (in quintiles) in our survey and assess its relation with TB prevalence.
The prevalence of bacteriologically confirmed TB was 307 per 100,000 population in persons aged ≥ 15 years (95%CI 249-366). After adjustment for confounders, prevalence was found to be associated with household expenditure level: the rate was 2.5 times higher for those in the lowest household expenditure quintile (95%CI 1.6-3.9) than those in the highest quintile.
With a set of nine household characteristics, we were able to predict household expenditure level fairly accurately. There was a significant association between TB prevalence rates and estimated household expenditure level, showing that TB is related to poverty in Viet Nam.
利用 9 种家庭特征，在越南全国结核病患病率调查中研究结核病与家庭支出之间的关联。
为了评估越南的结核病流行率，2006 年至 2007 年进行了全国分层聚类抽样调查。每个家庭都按照第二次越南生活水平调查（VLSS）的 9 项家庭特征进行评分。在 VLSS 数据集中，我们将这 9 项特征与人均家庭支出进行回归，并使用系数预测我们调查中的家庭支出水平（五分位数），并评估其与结核病流行率的关系。
≥15 岁人群中经细菌学证实的结核病患病率为 307/100000 人（95%CI 249-366）。在调整混杂因素后，发现患病率与家庭支出水平有关：最低家庭支出五分位数（95%CI 1.6-3.9）的患病率是最高五分位数的 2.5 倍。
我们使用 9 组家庭特征能够相当准确地预测家庭支出水平。结核病患病率与估计的家庭支出水平之间存在显著关联，表明结核病与越南的贫困有关。
