    Abstract:
    Between 1993 and 1995, we surveyed 4931 licensed anglers aged 17-34 years residing in 10 Michigan counties bordering a Great Lake. Responses were received from 1443 anglers and 844 of their partners. Lifetime sport-caught fish consumption was estimated as the number of sport-caught fish meals consumed in the previous 12 months times years since 1970 in which sport-caught fish were consumed. Analysis was restricted to currently married couples (n=626). Lifetime sport-caught fish consumption was categorized in men as 0 (14%); 1-114 (27%); 115-270 (30%); 271-1127 (29%) meals; and in women as 0 (28%); 1-54 (26%); 55-138 (27%); fand 139-1127 (19%) meals, respectively. Conception delay (ever having failed to conceive after 12 months of trying) was reported by 13% of both men and women. Among men, the unadjusted odds ratios (OR) for conception delay were 1.2, 1.3, and 2.0 across the three increasing levels of sport-caught fish consumption compared to none (trend test P=0.06). After adjustment for age, race, region of Michigan, household income, educational attainment, smoking, alcohol consumption, and partner's sport fish consumption, the OR for conception delay in men were 1.4, 1.8, and 2.8, respectively. In women, unadjusted OR for conception delay were 0.9, 1.0, and 1.4 with increasing sport-caught fish consumption (trend test P=0.35). With the same covariates and the sport-caught fish consumption of the woman's partner included in the model, the OR were 0.8, 0.8, and 1.0, respectively. These data suggest a modest association, in men only, of sport-caught fish consumption with risk of conception delay.
