Yu K, Lv J, Qiu Get al. - A prospective cohort study was conducted to determine the association between cooking fuels and the risk of all-cause and cardiopulmonary mortality in urban China. The China Kadoorie Biobank (CKB) Study included individuals aged 30–79 years from ten areas across China; we chose to study participants from five urban areas where the transition from the use of solid fuels to clean fuels for cooking was prevalent. Individuals who reached regular cooking (weekly or more frequently) at baseline were classified as persistent clean fuel users, previous solid fuel users, or persistent solid fuel users, according to self-reported fuel use histories. This study included a total of 226,186 individuals living in five urban areas of China between June 24, 2004, and July 15, 2008. The evidence showed that solid fuel use for cooking is correlated with a higher risk of mortality, and cessation of solid fuel use cuts excess mortality risks swiftly and substantially within 5 years. Even among people who persistently use clean fuels, ventilation use also lowers the risk of mortality. It is of prime interest for both policymakers and the public to expedite the transition from solid fuels to clean fuels and support efficient ventilation to minimize further adverse health effects.
