Female reproductive factors and risk of lymphoid neoplasm: The Japan Public Health Center-based Prospective Study.

ABSTRACT: Although a possible role of reproductive factors in lymphomagenesis has been hypothesized, results of epidemiological studies have been inconsistent. Here, we investigated the association between reproductive factors and the risk of lymphoid neoplasm and its subgroups. We used data from a large-scale, population-based prospective study in a Japanese cohort with 42 691 eligible women aged 40-69 years from 1990 to 1994. During a mean follow up of 18.7 years, we identified 176 cases of lymphoid neoplasm and 90 of non-Hodgkin lymphoma (NHL). A multivariable-adjusted Cox proportional hazards regression model was used to estimate hazard ratios (HR) and 95% confidence intervals (95% CI) for the risk of lymphoid neoplasms and its subgroups according to self-reported reproductive factors.
