| Résumé : | [BDSP. Notice produite par INIST CFkR0x9p. Diffusion soumise à autorisation]. Objectives. This study investigated whether an apparent downturn in prevalence rates of mammography use reported in the 1992 Behavioral Risk Factor Surveillance System (BRFSS) questionnaire resulted from a change in questionnaire wording. Methods, in a pretest-posttest design (1990-1991 vs 1992), piecewise linear regression analyses were based on monthly prevalence estimates of mammography use among female BRFSS respondents 40 years or older. Resuits. Self-reported mammography use was lower by 3.5 percentage points (95% confidence interval [CI]=1.5,5.5) overall and lower by 13.6 percentage points (95% CI=2.6,24.6) among Black women with less than a high school education when predicted from 1992 data than when predicted from 1990-1991 data. Conclusions. A change in questionnaire wording in the BRFSS caused demographic-specific effects in population-based estimates of mammography use. |
