This study aimed to assess the effects of biomass smoke exposure on lung function in a Nepalese population addressing some of these methodological issues from previous studies.We carried out a cross-sectional study of adults in a population exposed to biomass smoke and a non-exposed population in Nepal. Questionnaire and lung function data were acquired along with direct measures of indoor and outdoor air quality.Ventilatory function (FEV1, FVC, FEF25-75) was significantly reduced in the population using biomass across all age groups compared to the non-biomass using population, even in the youngest (16-25) age group [mean FEV1 (95% CI) 2.65 (2.57-2.73) vs. 2.83 (2.74-2.91), p=0.004]. Airflow obstruction was twice as common among biomass users compared to liquefied petroleum gas users (8.1% vs. 3.6%, p
