Hazard ratios (HR) and associated 95% CIs were calculated by Cox hazard proportional models after adjusting for sex, age, education levels, occupation, marital status, smoking, alcohol drinking, fruit intake > = 250 g/week, vegetable intake> = 250 g/day, physical exercise, hypertension, diabetes, and history of stroke, myocardial infarction, chronic respiratory diseases, and kidney diseases.
