OBJECTIVES. Recent legislation will improve insurance coveragefor screening mammography and effectively lower its cost tomany women. Although cost has been cited as a barrier to use,evidence of the magnitude of its effect on use is limited. METHODS.Mammography use in the past 2 years among women aged 50 to 75residing in four suburban or rural counties in Washington Statewas estimated from 1989 survey data. Logistic regression analysiswas used to estimate the odds ratio of mammography use as afunction of economic and other variables. Within a residentialarea, averages were used to measure the market price of mammographyand the time cost to obtain a mammogram. RESULTS. Use was loweramong women who faced a higher net price or who preferred toobtain a mammogram during weekend or evening hours and higheramong women with higher incomes. Visiting no doctor regularlyand smoking were predictors of failure to use mammography. CONCLUSION.The effects of economic variables on mammography use are importantand stable across subsets of the population, but they are modestin size.
