Impact of a cleaner‐burning cookstove intervention on blood pressure in Nicaraguan women
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 aged 40 or more years 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.
