Background Smoking accounts for >50% of bladder cancers (BCs) in men and 30% in women. Our aim is to explore this large discrepancy by contrasting countries with distinct smoking patterns and habits as these might explain sex differences for BC.
Methods Temporal patterns in BC incidence rates, lung cancer (LC) death rates, smoking prevalence and cigarette consumption across time by sex were analyzed by calculating annual percent changes (APCs), using joinpoint regression, for Spain (1973–97), Sweden (1958–97) and the UK (1960–97).
Results APCs for overall BC incidence rates were increasing for both sexes, ranging from 1.43% (1.25; 1.60) (British men) to 3.79% (3.15; 4.44) (Spanish men). APCs for overall LC death rates were also increasing in Sweden and Spain, but the UK showed decreasing APCs for LC death rates in men: –0.48% (–0.86; 0.10). Spain showed decreasing APCs for smoking prevalence among men and increasing APCs among women, –1.65% (–1.79; –1.51) and 2.48% (1.97; 3.00), respectively, but no differences by sex were found for the UK and Sweden.
Conclusions Findings indirectly reflected lag-time of minimum 30 years between smoking and onset of BC. The lack of sex differences for APCs of BC across these countries suggests potential contributions of changes in other population exposure levels.
