Household Solid Fuel Use and Cardiovascular Disease in Rural Areas in Shanxi, China.
BACKGROUND
More than 80 percent of the China's population is located in the rural areas, 95 percent of which use coal, wood etc for cooking and heating. Limited by data availability, the association between household solid fuels and cardiovascular diseases (CVDs) in China's rural areas is ignored in prior studies.


METHODS
This cross sectional study was conducted from 2010-2012 and carried out on rural population aging 20-80 yr, comprised of 13877 participants from eighteen villages. Self-report questionnaire data were collected. Each outcome represents whether the participant has a kind of CVDs or not and it is reported in participants' questionnaire. Then the collected data is analyzed by logistic regression models with odds ratios (OR) and 95 percent confidence interval.


RESULTS
After adjusting for potential confounders, the use of household solid fuels was significantly associated with an increased risk for hypertension (OR 1.751), CHD (OR 2.251), stroke (OR 1.642), diabetes (OR 1.975) and dyslipidemia (OR 1.185). Residents with the highest tertile of the duration of household solid fuel exposure had an increased odd of hypertension (OR 1.651), stroke (OR 1.812), diabetes (OR 2.891) and dyslipidemia (OR 1.756) compared with those in the lowest tertile of the duration of solid fuel exposure.


CONCLUSIONS
Indoor pollution exposure from household solid fuels combustion may be a positive risk factor for CVDs in the perspectives of China's rural population. Our findings should be corroborated in longitudinal studies.
