Age-adjusted odds ratios (OR) for obesity of the male smokers by the number of cigarette per day (CPD) and the duration of smoking.

<p>Age-adjusted ORs for obesity of the categories stratified by both CPD and duration of smoking in male current smokers and male past smokers. CPD was stratified by ≤ 10, 11–20, and >20. Duration of smoking was stratified by <10 years, 10–34 years, and ≥35 years.</p
