PURPOSE: Risk factors for @entity1778 and @entity706 in adults are largely unknown. This study was aimed at evaluating the association between lifestyle factors and the risk of @entity1583 in an adult population. METHODS: Data were drawn from a population-based case-control study carried out in Italy and included 294 cases (199 lymphoid and 95 myeloid) and 279 controls. Analyses were performed using standard multivariable logistic regression. RESULTS: Hair dye use for at least 15  years was associated with a higher risk of @entity706 among females (OR 2.3, 95  % CI 1.0-4.9, p  =  0.036, test for trend). Furthermore, a protective effect of a moderate to heavy tea consumption on the risk of @entity5 was observed (OR 0.4, 95  % CI 0.2-0.9, p  =  0.017). No association was found for the use of alcoholic beverages and @entity286 smoking. CONCLUSIONS: Our results confirm the potential carcinogenic effect of prolonged hair dye use observed in previous investigations. The excess risk could be explained by exposure to a higher concentration of toxic compounds in hair products used in the past. The protective effect of regular tea consumption observed in an area with a very high prevalence of black tea consumers deserves further investigation.
