“…The effect of HAP exposure on FVC was not as pronounced, explaining the overall decrease in prebronchodilator FEV 1 /FVC among those exposed to biomass overtime. Several cross-sectional studies have found exposure-response relationships between (39,40) . Longitudinal studies, however, have not demonstrated improved FEV 1 with reduction in HAP exposure, although analysis of lung function has so far been limited because of short follow-up periods (41).…”

BackgroundThe relationship between smoking, household pollution, dual exposure and severity of asthma in adults has not been sufficiently studied. We examined and compared the effects of cigarette smoking, domestic wood burning pollution and dual exposure (tobacco and wood burning) upon asthma severity in adults.MethodsThis was a cross-sectional study performed with 452 individuals with mild to moderate asthma and 544 patients with severe asthma (previously untreated). Smoking and exposure to wood smoke were identified and quantified through questionnaires to evaluate current and/or previous exposure; objective determination of cigarette exposure was obtained through the measurement of urinary cotinine. Asthma control was evaluated through Asthma Control Questionnaire; and severity was classified according to the Global Initiative for Asthma criteria. Subjects were grouped according to exposure type into 4 groups: smokers, household pollution, dual-exposure and no-exposure. Chi square, Mann–Whitney, and Kruskal–Wallis tests were used for comparisons between groups.ResultsOut of 996 included individuals, 78 (7.8%) were exposed to cigarette smoking alone, 358 (35.9%) to household pollution alone, 155 (15.6%) to the two exposures combined and 405 (40.7%) were not exposed. Compared to unexposed individuals, exposure to household pollution resulted in poorer asthma control, higher proportion of severe asthma, and worse indicators of lung function. The double-exposed individuals were worse off in all the evaluated parameters, and they were significantly worse than subjects with single exposure to household air pollution in relation to asthma severity and lung function. These subjects were predominantly females, older, with longer residence time in rural areas, lower income and lower schooling levels. Multivariate analysis showed that exposure to household pollution and double exposure were predictive factors associated with lack of control and increased severity of asthma.ConclusionsExposure to household pollution is associated with poorer control, greater severity, and poorer pulmonary function; double-exposed individuals have a greater risk of severe asthma and decreased lung function than those exposed only to household pollution.

“…Kurmi et al (2010) find higher odds of having COPD among households that use solid fuels. In India, McKay et al (2012); Moschovis et al (2015); Dave et al (2017) have found sex, smoking status, and indoor air pollution to be significant predictors of lung obstruction. However, some studies (Amaral et al, 2017;Sana et al, 2018) have failed to find significantly higher odds of COPD among those who used solid fuels.…”

Chronic respiratory conditions are a leading cause of death in the world. Using data on lung obstruction from the WHO Survey of Global AGEing and Adult Health (WHO-SAGE 2007-08), this paper studies the determinants of respiratory health in India, home to a third of all deaths from Chronic Obstructive Pulmonary Disease. First, we find that smokers and members of households that use solid fuels (wood, biomass, coal or dung) for cooking have higher lung obstruction. Second, even if a respondent's household uses clean fuels, their lung obstruction is higher if their neighbors use solid fuels. In neighborhoods with high solid fuel use, the lungs of members of households that use clean fuels can be as obstructed as lungs of members of households that use solid fuels. These negative externalities of solid fuel use are robust to additional controls for neighborhood socioeconomic status, falsification tests, tests with placebo measures, and tests using alternative measures of respiratory health as outcomes. Third, the influence of the determinants is patterned by gender. Smoking tobacco is an important influence on lung obstruction among men. Confirming non-linear dose-response relationships, we find that women from households that use solid fuels are the only group not further harmed by neighborhood solid fuel smoke, possibly because of high exposure to pollutants while cooking. The study improves our understanding of behavioral, social, and environmental determinants of respiratory health in India. Importantly, it makes a case for greater public investments to promote the adoption and use of cleaner fuels.
