Abstract
Infectious mononucleosis (IM) is an established risk factor for Hodgkin's disease (HD). A substantial minority (33%) of cases of HD have Epstein‐Barr virus (EBV) DNA within the malignant cells (are EBV^+ve^). It is unclear whether risk after IM applies specifically to EBV^+ve^ HD. We report the results of a population‐based case‐control study of HD in adults (n = 408 cases of classical HD, 513 controls) aged 16–74 years; the case series included 113 EBV^+ve^ and 243 EBV^‐ve^ HD. Analyses compared total HD, EBV^+ve^ HD and EBV^‐ve^ HD with the controls and EBV^+ve^ HD with EBV^‐ve^ HD cases using, mainly, logistic regression. Regression analyses were adjusted for gender, age‐group and socioeconomic status, and were performed for the whole age range and separately for young (< 35 years) and old adults (≥ 35 years); formal tests of effect modification by age were included. For the young adults, reported IM in index or relative was strongly and significantly associated with EBV^+ve^ HD when compared to controls (odds ratio [OR] = 2.94, 95% confidence interval [CI]: 1.08–7.98 and OR = 5.22, 95% CI: 2.15–12.68, respectively). These results may be interpreted as indications that late first exposure to EBV increases risk of HD, especially in young adults; this applies primarily to EBV^+ve^ HD. © 2003 Wiley‐Liss, Inc.
