Abstract

OBJECTIVE:

To examine the relationship between obesity and mammography use in a large population of black and white women.

METHODS:

Baseline data from 18,756 black and 6,304 white women enrolled in the Southern Community Cohort Study were used to examine the association between body mass index categories (healthy weight: 18.5-24.9 kg/m(2), overweight: 25-29.9 kg/m(2), and obesity classes I: 30-34.9 kg/m(2), II: 35-39.9 kg/m(2), and III: 40+ kg/m(2)) and mammogram use in the past two years. Cross-sectional analyses were conducted using logistic regression controlling for socioeconomic measures, medical conditions, insurance coverage, and lifestyle factors.

RESULTS:

Among white women, obesity class III was associated with a reduced likelihood of recent mammography compared to healthy weight women (OR = 0.70, 95% CI 0.56-0.87) that appeared unrelated to income and insurance coverage. A deterring effect of obesity was not evident among black women; instead, overweight and obesity were associated with small elevations in mammography use compared to healthy weight.

CONCLUSIONS:

In light of rising obesity rates and known associations between obesity and breast cancer risk and prognosis, a deterring effect of extreme obesity on mammography screening for white women is a concern that should be addressed by screening programs and by further directed research into the factors underlying this association.
