title: Association of smoking status with obesity and diabetes among elderly people.
abstract: The present study was aimed to examine associations of current and ex-smoking status with obesity and diabetes among elderly people. Nationwide study of Finnish elderly people based on biennial surveys from 1985 to 1995, were used to study 7482 people aged 65-79 years. Smoking status included non-, ex-light, ex-heavy, current light, and current heavy smokers. Obesity was set as body mass index (BMI) > or = 30. Information of smoking, BMI, and diabetes was based on self-reports. Logistic regression was used as the main method of analyses. Compared to non-smokers (reference category), ex-heavy smokers had higher (odds ratio, 1.42; 95% confidence interval: 1.09, 1.85) and current light smokers (OR, 0.46; 95% CI: 0.31, 0.69) lower relative risk of obesity. Current light smokers had also lower and ex-heavy smokers higher rate of diabetes than non-smokers. Ex-heavy smokers had a higher risk of obesity (OR, 1.75; 95% CI: 1.30, 2.36) and diabetes (OR, 1.48; 95% CI: 1.10, 2.01) than ex-light smokers. Same pattern for current smokers was found. Heavy ex- and current elderly smokers are at risk of obesity and diabetes. Thus, heavy smokers should be emphasized in programs promoting smoking cessation.
