The International Agency for Research on Cancer (IARC) classified occupational painting as a human carcinogen based on lung and bladder cancers; however, no specific exposures were implicated. The authors conducted comprehensive meta-analyses of the epidemiological literature on occupational painting and these cancers. The authors abstracted study results and confounder information, and used quantile plots and regression models to evaluate heterogeneity and publication bias. Summary risk estimates were derived and sensitivity analyses performed to evaluate smoking, socioeconomic status (SES), and exposure variables. Where applicable, a Bayesian approach was used to externally adjust for smoking, a major risk factor for both cancers. For lung cancer cohort mortality studies, publication bias and heterogeneity were seen, and earlier studies reported higher risk estimates than later studies. Overall lung cancer summary risk estimates were 1.29 for case-control and 1.22 and 1.36 for cohort morbidity and mortality studies, respectively, and risk estimates for bladder cancer were 1.28 for case-control and 1.14 and 1.27 for cohort morbidity and mortality studies, respectively (all statistically significant). Risks did not differ between painters and mixed occupations. Nonsignificant summary estimates resulted for lung and bladder cancers when controlling for SES, or externally adjusting for smoking in lung cancer studies. Summary risks varied by control source for case-control studies. Residual confounding by smoking and SES, lack of exposure group effect, and publication bias limit the ability of the meta-analyses to explain associations observed between occupational painting and lung and bladder cancers. Given the long latencies for lung and bladder cancers, these weak associations, if real, may not be elucidated through studies of occupational painting today.

“…An increased risk of bladder cancer has been observed among hairdressers and barbers in a number of cohort,2, 22, 23, 24, 25, 26, 27, 28 and case‐control studies 1, 9, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38. Based on these and other data, the International Agency for Research on Cancer (IARC) classified employment as a hairdresser or barber as involving occupational exposures as Group 2A: probably carcinogenic to humans 39.…”

Bladder cancer risk and personal hair dye use

Several cohort and case-control studies have found an increased risk of bladder cancer among hairdressers and barbers who are occupationally exposed to hair dyes. However, the carcinogenic risk associated with personal use of hair dyes remains uncertain since several large case-control and cohort studies did not find an association between personal hair dye use and bladder cancer. To address this question, the authors used data collected on 459 bladder cancer cases and 665 controls who were interviewed as part of a case-control study conducted in New Hampshire between 1994 and 1998. Participants underwent a structured personal interview with regard to history of hair dye use and bladder cancer risk factors. Unconditional logistic regression analysis was used to compute odds ratios that were associated with hair dye use, while controlling for potential confounding factors. A history of any hair dye use was inversely associated with bladder cancer incidence in men [adjusted odds ratio (OR) ‫؍‬ 0.5; 95% confidence interval (CI)‫-3.0؍‬ 0.8], although risk reductions were not statistically significant for individual dye types. In women, use of permanent (adjusted OR ‫؍‬ 1.5; 95%CI ‫؍‬ 0.8 -2.7) and rinse-type hair dye (adjusted OR ‫؍‬ 1.7; 95%CI ‫؍‬ 0.8 -3.6) were associated with a modestly elevated risk of bladder cancer but with limited statistical precision; no association was found with use of semi-permanent dyes (adjusted OR ‫؍‬ 0.7; 95%CI ‫؍‬ 0.3-1.4). For permanent hair dye use, odds ratios were most pronounced for younger age at first use, higher frequency and prolonged time since first use; however there were no clear trends in risk by these factors. In light of the prevalence of hair dye use, further studies are needed that address the effects of specific colors and types of hair dyes along with the possible role of individual susceptibility. © 2004 Wiley-Liss, Inc. Key words: hair dye; bladder cancer; permanent dye; case-control; logistic regressionIt is estimated that about 33% of women above age 18 and over 10% of men over age 40 in the USA use hair dyes. 1 Occupational use of hair dyes by hairdressers and barbers has been associated with an increased risk of bladder-cancer in a number of cohort and case-control studies. 1 Combined, the cohort studies estimated a relative risk of bladder cancer associated with occupational exposure to hair dyes of 1.4 for 81,075 subjects (RR ϭ 1.1 for females, RR ϭ 1.6 for males), although control for smoking may be problematic. 1 Results of a recent follow-up cohort study in Sweden indicated an excess risk of bladder cancer among male hairdressers working at the 1960 census [standardized incidence ratio (SIR) ϭ 1.25; 95% confidence interval (CI) 1.1-1.6], however no excess risk was observed in recent decades. 2 Furthermore, the carcinogenic risk associated with personal use of hair dyes remains unclear. Several large studies, including the Nurses' Health cohort study 3 and the American Cancer Society cohort study, 4,5 indicated no increased risk of bladder cancer among ...
