BRFSS: Behavioral Risk Factor Surveillance System Survey
Recent use of mammography was defined by self-report receipt of a mammogram within the past two years.
Percent of Cohort gives the distribution of each characteristic within the cohort. Percent with Mammogram gives the percent of women in each row who reported a recent mammogram.
Adjusted OR: Odds ratio for impact of characteristic on odds of recent mammogram, adjusted for other characteristics in table.
Inadequate county mammography capacity was defined as <1.2 mammography machines per 10,000 women age 40+ in the county of residence.
All estimates, other than actual sample size (N), were weighted to account for the probability of sample selection and for post-stratification adjustment for non-response and non-coverage of households without telephones.
