  1. Prevalence at subgroup levels is adjusted for age and regions as appropriate
  2. *Except for age and regions, characteristics were based on the characteristics of the participants collected at the resurvey
  3. ^Among baseline non-drinkers, associations between change in drinking status and factors were tested by logistic regression adjusting for age and region: p < 0.001 for trend across birth cohorts and p < 0.02 for heterogeneity across regions, income and self-reported health
  4. #Among baseline drinkers, associations between change in drinking status and factors were tested by multinomial logistic regression adjusting for age and region: p < 0.02 across all variables except education
  5. aPoor self-reported health status include those who reported fair or poor self-rated health; Good self-reported health status include those who reported good or excellent self-rated health
  6. bDiagnosed with one or more of: coronary heart disease, stroke, transient ischaemic attack, diabetes, cancer, tuberculosis, chronic hepatitis/cirrhosis, rheumatoid arthritis, peptic ulcer, chronic respiratory disease, gallstone/gallbladder disease, kidney disease
  7. cDerived by summing the individual scores of each of the four risk factors (0 if no, 1 if yes): regular smoking, lack of daily fruit intake, hypertension, low physical activity
