BACKGROUND:Evidence points to a clear link between air pollution exposure and several chronic diseases though investigations regarding arthritis are still lacking. Emerging evidence suggests an association between ambient air pollution and rheumatoid arthritis. Household air pollution exposure, conversely, is largely unstudied but may be an important consideration for arthritis, particularly in low- and middle-income countries (LMICs), where cooking and heating activities can generate high indoor air pollutant levels. METHODS:We investigated the association of household air pollution (electricity vs. gas; kerosene/paraffin; coal/charcoal; wood; or agriculture/crop/animal dung/shrubs/grass as the main fuel used for cooking) and arthritis in six LMICs (China, Ghana, India, Mexico, the Russian Federation, South Africa) using data from Wave I of the World Health Organization Study on Global AGEing and Adult Health (SAGE) (2007-2010). Multivariable analyses were adjusted for sociodemographic, household and lifestyle characteristics and several comorbidities. RESULTS:The use of gas (aOR = 1.76, 95%CI: 1.40-2.21); coal (aOR = 1.74, 95%CI: 1.22-2.47); wood (aOR = 1.69, 95%CI: 1.30-2.19); or agriculture/crop/animal dung/shrubs/grass: aOR = 1.95 (1.46-2.61) fuels for cooking were strongly associated with an increased odds of arthritis, compared to electricity in cluster and stratified adjusted analyses.
