Résumé (Abstract) Household Air Pollution (HAP) increases the risk for cardiovascular (CVD) and respiratory diseases, especially in low-or-middle income countries. To measure the metabolic syndrome is an established proxy to assess the risk for CVD. HAP increases the risk of developing CVDs in patients with MS, but it has not been fully understood if HAP can be a cause for MS itself

We evaluated for the first time in a rural high altitude Andean population the impact of HAP reduction and personal exposure after the installation of an improved cookstove on the metabolic risk factors.

The project was embedded within a randomised controlled trial with a 2x2 full factorial design with 317 children enrolled from 102 rural communities in the Peruvian Andes. The trial assessed child diarrhoea and respiratory morbidity and improvements in early child development (ECD) in children <2. The study groups comprised of a home-based environmental intervention (improved cook stove, drinking water, food- and hand-hygiene “IHIP”) and an “ECD” intervention. For this study, we considered both parents of these children as study subjects. Participants completed a socioeconomic and a 24-hour food recall questionnaire and went through a health check including waist circumference, blood pressure, lipids (triglycerides and HDL cholesterol) and glucose capillary blood levels. We used the Joint Interim Statement of the International Diabetes Federation Task Force to define MS. HAP was measured as CO (carbon monoxide) and PM 2.5 (particulate matter) concentrations in 80 participants households.

In total 392 subjects participated in the study: 192 in the IHIP intervention arm, 200 in the control arm. 237 women and 155 men participated. We found a total MS prevalence of 17%, 21% in women and 11% in men. However, the prevalence did not differ by study group (17% in both) but it was close to the national average.

Even though the clean cook stove intervention decreases HAP levels, concentrations still exceeded the WHO thresholds continuing potentially to affect people’s health; this explains similar prevalence in both arms, and higher rates in women who spend more day time indoor exposed to cooking and cleaning.
