PURPOSE: Smoke from combustion of biomass cooking fuels is a major source of household indoor air pollution in India. Although health hazards related to such exposure are well-recognized, its effect on people’s perceived health-related quality of life (HRQL) is not clearly known. We evaluated effect of exposure to smoke from wood combustion while cooking on HRQL in apparently healthy north Indian women.
METHODS: 85 adult women (>15 years of age) regularly using wood as cooking fuel during past 12 months (Group 1), and 85 women regularly using liquefied petroleum gas (LPG) for cooking (Group 2), were studied. No subject had any current or past cardiorespiratory illness or any other medical condition likely to impair HRQL. The Hindi version of abbreviated World Health Organization Quality of Life (WHOQOL-Bref) questionnaire was used to assess HRQoL in four domains (physical, psychological, social relationships, and environment). All subjects self-completed the WHOQOL-Bref by responding to each of its 26 items on a five-point Likert scale. Mean domain scores were compared between the two groups, after transformation to a scale of 0-100, with higher scores implying better HRQoL. The study was approved by our Institutional Ethics Committee and informed consent was obtained from all participants.
RESULTS: Mean (±SD) age, years of cooking, and hours spent daily in kitchen, were similar between women in Group 1 and Group 2 (38.3±10.7 years vs. 38.5±9.9 years, 26.2±11.7 years vs. 25.4±10.6 years, and 4.2±1.7 hours vs. 4.1±1.6 hours respectively). Mean (±SD) WHOQOL-Bref scores in physical, psychological, social relationships, and environment domains were significantly reduced in women in Group 1 as compared to women in Group 2 (69.9±22.8 vs. 76.9±12.3, p 0.015; 57.3±16.8 vs. 74.1±9.2, p <0.001; 59.4±26.0 vs. 85.7±12.8, p <0.001; 58.6±18.0 vs. 84.6±12.1, p <0.001 respectively).
CONCLUSIONS: HRQL is impaired across domains among healthy Indian women exposed to smoke from wood combustion while cooking, as compared to those using LPG, universally considered a clean cooking fuel.
CLINICAL IMPLICATIONS: Exposure to smoke from biomass fuel combustion may have adverse health implications, even in those not diagnosed to have any respiratory disorder related to such exposure. Biomass fuels should preferably be replaced with cleaner fuels for domestic cooking.
