Lymphomas are a heterogeneous group of malignancies of the immune system. Recent studies suggest that immunological conditions which are modulated by lifestyle-dependent environmental determinants might affect lymphoma risk. We used data from Epilymph, a European multi-centric case-control study with 2480 cases and 2540 controls, to analyse the relationship between lifestyle-dependent immunological determinants and risk of lymphomas. We found an inverse relationship between risk of lymphoma and allergies, mainly respiratory (OR = 0.86, CI = 0.89-1.01) and food allergies (OR = 0.67, CI = 0.52-0.85), a slightly elevated lymphoma risk for first-born children (OR = 1.17, CI = 0.99-1.39) and only children (OR = 1.10, CI = 0.86-1.39). The inverse relationship between atopic disorders and risk of lymphomas is consistent with earlier observations. Our findings on birth order and lymphoma increase the inconsistency of findings across studies and suggest a critical reappraisal of potential underlying mechanisms. © 2007 Elsevier Ltd.

Abstract
Lymphomas are a heterogeneous group of malignancies of the immune system. Recent studies suggest that immunological conditions which are modulated by lifestyle-dependent environmental determinants might affect lymphoma risk. We used data from Epilymph, a European multi-centric case-control study with 2480 cases and 2540 controls, to analyse the relationship between lifestyle-dependent immunological determinants and risk of lymphomas. We found an inverse relationship between risk of lymphoma and allergies, mainly respiratory (OR = 0.86, CI = 0.89-1.01) and food allergies (OR = 0.67, CI = 0.52-0.85), a slightly elevated lymphoma risk for first-born children (OR = 1.17, CI = 0.99-1.39) and only children (OR = 1.10, CI = 0.86-1.39). The inverse relationship between atopic disorders and risk of lymphomas is consistent with earlier observations. Our findings on birth order and lymphoma increase the inconsistency of findings across studies and suggest a critical reappraisal of potential underlying mechanisms. © 2007 Elsevier Ltd.
