Lower hormone therapy use linked to decline in mammography rates in U.S. women aged 50 to 64
TUESDAY, Aug. 23 (HealthDay News) -- The decrease in hormone therapy (HT) use seen in the United States is correlated with a decrease in mammography rates among U.S. women aged 50 to 64 years, but not in women 65 years or older, according to a study published online Aug. 22 in Cancer.
Nancy Breen, Ph.D., from the National Cancer Institute in Bethesda, Md., and colleagues investigated whether the decrease in HT use by 2005 in the United States was associated with decreased mammography rates in women aged 50 years or older. Data on HT and mammography use were collected from 2000 and 2005 National Health Interview Surveys. After adjusting for measurable factors, the interaction between HT use and survey year was tested using multivariate logistic regression analysis.
The investigators found that a recent mammogram was more likely to be reported by women in the age group 50 to 64 years if they were more educated, had a usual source of care, had private health insurance, were from any race except non-Hispanic Asian, had talked with an obstetrician/gynecologist or other physician in the past 12 months, or were currently taking HT. A recent mammogram was more likely in women age 65 years or older if they were a younger age (65 to 74 years), more educated, had a usual source of care, had Medicare Part B or other supplemental Medicare insurance, were in excellent health, were any race except non-Hispanic Asian, talked with an obstetrician/gynecologist or other physician in the past 12 months, or were currently taking HT.
"The change in HT use was associated with the drop in mammography use for women ages 50 to 64 years but not for women aged ≥65 years," the authors write.
