Abstract Background: Household air pollution increases the risk of non-communicable diseases, such as cardiovascular diseases and metabolic syndrome. This study hypothesised that the reduction of household air pollution through the installation of improved cookstoves is associated with the prevalence of metabolic syndrome. We compared the prevalence of metabolic syndrome between adults using open fire stoves and using improved cookstoves in high altitude provinces of Cajabamba and San Marcos in rural Peruvian Andes.Methods: This is a quasi experimental study nested within a randomised controlled trial (parent study) of 317 children randomised in four study arms. The parents study applied a 2x2 factorial design with three single intervention arms (improved cookstove (ICS), early child development (ECD) and Control) and one combined arm (ICS-ECD). This study was conducted 6-10 months after the ICS intervention was implemented and all parents of the 317 children in the parent study were eligible to participate. Ventilated improved cookstoves using biomass fuel were provided to intervention homes. All participants answered a 24-hour food recall and underwent a physical examination for metabolic syndrome diagnosis. Results: A total of 385 participants were allocated to two groups of improved cookstove users with 190 (112 women and 78 men) and open-fire stove users with 195 (123 women and 72 men). Metabolic syndrome was detected in 21% of all participants and more frequently in women than men (26% versus 13%). In women, the improved cookstove intervention was a protective factor for metabolic syndrome (Prevalence Ratio= 0.70 (0.46 to 1.08), p=0.11). In addition, PR increased with age in women. In both gender, significantly lower PR was found in participants living ≥2500 meters above sea level (PR=0.65 (0.42 to 1.00), p=0.051 in women; (PR=0.25 (0.07 to 0.71), p=0.009 in men).Conclusions: The improved cookstove intervention reducing household air pollution is associated with a lower prevalence of MetS in women users. In addition, residential altitude is an important risk factor for metabolic syndrome even in high altitude populations.

The Relationship

Background: Household air pollution from biomass fuel use affects 3 billion people worldwide. There are few studies that examine the relationship between biomass fuel use and blood pressure. We sought to determine if daily biomass fuel use was associated with higher blood pressure and increased hypertension in Peru. Methods: We analyzed baseline information from an age- and sex-matched, population-based study in Puno, Peru. Daily biomass fuel use was self-reported. Hypertension was defined as a systolic blood pressure (SBP) ≥140 mmHg; diastolic blood pressure (DBP) ≥90 mmHg; or self-report of diagnosis and anti-hypertensive medications. We used linear and logistic multivariable regressions, adjusting for age, sex, daily cigarette use and body mass index, to examine the relationship between daily biomass fuel use with blood pressure and hypertension, respectively. Results: Data from 1004 individuals (mean age 55.3 years, 51.7% female) were included. There was evidence of an association between daily biomass fuel use and hypertension (adjusted OR = 2.1, 95%CI 1.2 to 3.5). Subjects who reported daily use of biomass fuels had 6.0 mmHg (95% CI 4.1 to 8.0) higher SBP and 4.8 mmHg (95%CI 3.5 to 6.0) higher DBP compared to those who did not use biomass fuels daily. In a secondary analysis, we used rural residence (vs. urban) as a proxy of biomass daily use and the relationship with hypertension and systolic blood pressure was similar: a higher odds of hypertension (adjusted OR = 2.1, 95%CI 1.3 to 3.6), and higher SBP (6.7mmHg, 95% CI 4.8 to 8.6) and DBP (5.5 mmHg, 95% CI 4.3 to 6.8) in rural vs. urban participants. Conclusion: Biomass fuel use is associated with increased odds of hypertension and higher blood pressure in Puno, Peru. Reducing exposure to air pollution from biomass fuel use represents a potential opportunity for cardiovascular prevention in rural communities worldwide. Longitudinal studies to evaluate the impact of reducing household air pollution are needed.

The Impact

The energy crisis and worsening ecological environment has become the biggest threats to human life. Using solid biomass fuel can effectively relieve these hazards. According to empirical analysis on peasant households' willingness of using solid biomass fuel, the results show that age、education and incomes of the farmers' families, energy satisfaction ,energy policies, farmers for solid biomass fuel concept cognitive degree, farmer's awareness of environmental protection and safety consciousness biomass fuel for farmers to buy solid has significant influence. Therefore it is suggested that implementing energy subsidies and strengthen the concept of product positioning that can expand propaganda in solid biomass energy and promote the impact peasant biomass fuel industry development of solid.
