We examine the impact of exposure to biomass burning events (primarily crop burning) on the prevalence of hypertension in four North Indian states. We use data from the National Family Health Survey-IV for 2015-16 and employ a multivariate logistic and linear model to estimate the effect of exposure to biomass burning on the prevalence of hypertension and blood pressure, respectively. The adjusted odds ratio of hypertension among individuals living in areas with high intensity of biomass (HIB) burning (defined as exposure to 100 fire-events during the past 30 days) is 1.15 [95% CI: 1.003-1.32]. The odds ratios further increase at a higher intensity of biomass burning and downwind fires are found to be responsible for the negative effect of fires on cardiovascular health. We also find that the systolic and diastolic blood pressure for older cohorts is significantly higher due to exposure to HIB. We estimate that elimination of HIB would prevent loss of 70-91 thousand DALYs every year and 1.73 to 2.24 Billion USD (in PPP terms) over 5 years by reducing the prevalence of hypertension. Therefore, curbing biomass burning will be associated with significant health and economic benefits in North India.
我们研究了暴露于生物质燃烧事件（主要是作物焚烧）对印度北部四个邦高血压患病率的影响。我们使用了2015 - 16年全国家庭健康调查-IV的数据，并采用多元逻辑回归和线性模型分别估计暴露于生物质燃烧对高血压患病率和血压的影响。生活在生物质高强度燃烧（HIB）地区（定义为过去30天内暴露于100次火灾事件）的个体中，高血压的调整比值比为1.15 [95%置信区间：1.003 - 1.32]。在更高强度的生物质燃烧情况下，比值比进一步增加，并且发现下风向火灾是火灾对心血管健康产生负面影响的原因。我们还发现，由于暴露于HIB，老年人群的收缩压和舒张压显著更高。我们估计，通过降低高血压患病率，消除HIB每年可避免7万至9.1万个伤残调整生命年（DALYs）的损失，并在5年内避免17.3亿至22.4亿美元（按购买力平价计算）的损失。因此，在印度北部，抑制生物质燃烧将带来显著的健康和经济效益。
