Lifestyle, sexual history, and medical history characteristics were analyzed as risk factors for non-Hodgkin's lymphoma (NHL) in a population-based case-control study of 1593 subjects with NHL and 2515 control subjects conducted in the San Francisco Bay Area between 1988 and 1995. The results for homosexual men, 312 with NHL and 420 control subjects, showed that HIV infection was associated with a 20-fold increased risk for NHL. Among HIV-positive homosexual men, after adjustment for other factors, those that were associated with a reduced risk for NHL were frequency of receptive anal intercourse between the ages of 20 and 29 (1 to 9 times: OR = 0.63; greater than or equal to 10 times: OR = 0.37; trend: p = 0.02), allergy to grass, hay, leaves, plants and pollen (OR = 0.35, CI = 0.19 to 0.64), number of bee or wasp stings (1 to 3 times: OR = 0.65; greater than or equal to 4 times: OR = 0.56; trend: p = 0.07), use of Tagamet (cimetidine) for 4 consecutive weeks or longer (OR = 0.39, CI = 0.17 to 0.89), vaccination against influenza (OR = 0.41, CI = 0.23 to 0.74), and lifetime frequency of amphetamine use (1 to 19 times: OR = 0.59; greater than or equal to 20 times: OR = 0.38; trend: p = 0.003). Among HIV-negative homosexual men, after adjustment for other factors, factors that were associated with NHL status were frequency of receptive anal intercourse between the ages of 20 and 29 (1 to 9 times: OR = 0.39; greater than or equal to 10 times: OR = 0.20; trend: p = 0.001), nonmedication allergies (OR = 0.43, CI = 0.21 to 0.89), vaccination against poliomyelitis at
