Abstract:
OBJECTIVETo explore the influence of smoking on chronic diseases among people with various income levels in China.
METHODSCross-sectional study on smoking behavior, chronic disease and income level was performed using database of the Second National Health Service Study (1998) provided by the Ministry of Health in China.
RESULTSCompared to never-smokers, smokers (including current smokers and former smokers) had a higher rate of having chronic diseases, after adjusted in age, income, educational level, employment status and type of jobs with corresponding countryside (OR = 1.185, 95% CI: 1.121 - 1.253 and town OR = 1.083, 95% CI: 1.010 - 1.161). Smoking had a more serious effect on having chronic illness in males from the countryside (former-smoker OR = 2.764, 95% CI: 2.471 - 3.092) than in town (former-smoker OR = 2.112, 95% CI: 1.844 - 2.419). Smokers at the lowest income level had a higher possibility of having chronic illness (town OR = 2.076, 95% CI: 1.551 - 2.780; countryside OR = 2.903, 95% CI: 2.248 - 3.749) than those at the highest income level (town OR = 1.785, 95% CI: 1.285 - 2.479 in the countryside OR = 2.466, 95% CI: 1.941 - 3.134).
CONCLUSIONSmoking might cause more serious health problems to people at lower income level in China.
