Abstract	Objective: A population-based cohort study was conducted to examine concordance of cancer incidence and lifestyle in married couples. Methods: Cancer incidence from 1 September 1986 to 30 June 2000 was followed for a baseline cohort of 2601 community-living married couples aged 40–84 years who were cancer-free and had completed an epidemiologic questionnaire in 1986 in Saitama, Japan. We computed age-adjusted cross-ratios: spouse-with/spouse-without rate ratios as a measure of association for paired rate data, using a bivariate survival analysis method. Results: Concordance of lifestyles for couples was high for dietary habits, and low for smoking and alcohol habits. During the 14 year follow-up, 464 cancer cases occurred (husbands only: 279, wives only: 119, both: 33 couples). Wives whose husbands developed cancer were at an increased risk of developing cancer themselves, compared with those whose husbands had not had cancer (CR: 1.70, 95% CI: 1.12–2.58). Mean age at diagnosis was 68.2 years for husbands and 66.0 years for wives. And correlation of cancer incidence was further seen among couples who shared habits of smoking and/or drinking. Conclusions: Our data suggest that shared lifestyles including smoking and drinking habits are associated with an excess concordance of cancer incidence among married couples.
