很少有研究评估了室内生物质燃烧对心血管相关的影响，或者年龄和肥胖状况等特征在这种关系中的作用。我们研究了清洁燃烧炉灶干预对基线使用明火的巴布亚妇女血压的影响;我们还评估了人口亚组的影响异质性。我们评估了74名女性厨师从基线到干预后（范围：273-383天）收缩压和舒张压的变化。我们测量了室内细颗粒物（PM2.5; n=25），室内一氧化碳（CO; n=32）和个人CO（n=30）浓度。观察到所有污染物的污染物浓度平均降低幅度很大;例如，干预后室内PM2.5降低了77%。然而，污染分布（基线和干预后）很广，而且相互重叠。虽然在整个人群中未观察到血压显著降低，但在40岁或以上的女性中观察到收缩压降低5.9 mmHg（95%置信区间[CI]：-11.3，-0.4），在肥胖女性中观察到收缩压降低4.6 mmHg（95% CI：-10.0，0.8）。这项研究的结果表明，某些亚组可能更有可能在炉灶干预后改善血压。
Few studies have evaluated the cardiovascular-related effects of indoor biomass burning or the role of characteristics such as age and obesity status, in this relationship. We examined the impact of a cleaner-burning cookstove intervention on blood pressure among Nicaraguan women using an open fire at baseline; we also evaluated heterogeneity of the impact by subgroups of the population. We evaluated changes in systolic and diastolic blood pressure from baseline to post-intervention (range: 273–383 days) among 74 female cooks. We measured indoor fine particulate matter (PM2.5; n=25), indoor carbon monoxide (CO; n=32), and personal CO (n=30) concentrations. Large mean reductions in pollutant concentrations were observed for all pollutants; for example, indoor PM2.5 was reduced 77% following the intervention. However, pollution distributions (baseline and post-intervention) were wide and overlapping. Although substantial reductions in blood pressure were not observed among the entire population, a 5.9 mmHg reduction (95% confidence interval [CI]: −11.3, −0.4) in systolic blood pressure was observed among women 40 or more years of age and a 4.6 mmHg reduction (95% CI: −10.0, 0.8) was observed among obese women. Results from this study provide an indication that certain subgroups may be more likely to experience improvements in blood pressure following a cookstove intervention.
