[BDSP. Notice produite par INIST-CNRS R0x3V3I6. Diffusion soumise à autorisation]. Despite screening for prostate cancer, mortality in the United States remains substantial. In northern New England, we know little about either determinants of stage at diagnosis-an important predictor of survival-or health outcomes for Franco-Americans, the region's largest ethnic minority. The objective of this investigation was to identify predictors of late prostate cancer stage in a rural, predominantly white state with a large Franco-American population. The Maine Cancer Registry provided incident cases from 1995 to 1998. We modeled individual-level variables (age, sex, race, French ethnicity by surname, and payer) and contextual/town-level variables (socioeconomic measures, population density, Franco ancestry proportion, distance to health care, and weather severity) with multiple logistic regression for late stage. We found that age categories 50-64,65-74, and 75-84 years-but not 40-49 years- (versus 85+) were protective for late stage, as was residence in higher snowfall areas. Diagnosis in the earlier years of the study, particularly for French-surnamed men, and residence in a high-Franco area conferred greater risk for late disease. However, in a two-way interaction, residence in towns with high Franco ancestry proportion protected French-surnamed men (OR=0.09, type 3 p
