Abstract
Aim
This study has examined the adverse effects of biomass burning on menstrual cycle and reproductive outcome in rural women of India.
Subjects and methods
227 premenopausal women (using wood, dung and agricultural wastes for cooking) and 177 women (using liquid petroleum gas, LPG) were recruited for this study. Personal data was collected through a structured questionnaire. PM10 levels in indoor air were measured by portable aerosol monitor. Cumulative exposure of these women were also estimated (in hour-years) taking into consideration the number of years of exposure to biomass smoke or LPG.
Results
Controlling the potential confounders, cumulative exposure to biomass smoke and PM10 from biomass burning substantially increased the odds of altered reproductive health outcomes among rural women. Positive association was observed between cumulative biomass smoke exposure and shortened menstrual cycle (OR = 5.1, 95 % CI 3.62–9.21), irregular cycle (OR = 1.8, 95 % CI 1.33–2.34), spontaneous abortions (OR =1.7, 95 % CI 1.10–4.10), stillbirths (OR = 2.1, 95 % CI 1.21–4.35) and low birth weight (OR = 6.1, 95 % CI 2.54–9.76) in newborns.
Conclusion
The study shows women cooking with biomass fuel are at heightened risk of developing reproductive problems, stillbirth and low birth weight in newborns. This study recommends that more efforts should be made to understand the problem and introduce strategies to reduce emissions and exposure to biomass smoke.
