Comparing screening and preventive health behaviors in two study populations: daughters of mothers with breast cancer and women responding to the behavioral risk factor surveillance system survey

Abstract

Background: Studies show that daughters of mothers with breast cancer may be at increased risk for developing the disease. However, daughters' adherence to health behavior and screening recommendations, compared to the general population, is unknown.

Methods: Telephone interviews explored characteristics of adult daughters (n=147), including primary and secondary preventive behaviors, body mass index (BMI, kg/m(2)), physical activity, fruit/vegetable intake, alcohol intake, smoking, and mammography. Daughters of mothers with breast cancer were recruited from the community and were compared with Virginia women (n=2528) from the 2005 Behavioral Risk Factor Surveillance System (BRFSS) survey. Differences were examined using logistic regression, adjusting for demographic covariates.

Results: Daughters were younger (p<0.001), more highly educated (p<0.001), and more likely to never have been married (p<0.001) than BRFSS participants, but groups were similar by race. In adjusted analyses, daughters were significantly more likely to have ever had a mammogram (p<0.001) and to have had one recently (p=0.001). Daughters also were significantly less likely to consume>3 fruit/vegetable servings daily (p=0.032) compared to BRFSS results. There were no differences in BMI, smoking rates, alcohol consumption, or level of physical activity at work.

Conclusions: Daughters with familial breast cancer risk were more likely to receive mammography screening than BRFSS participants, but they were no different in BMI, physical activity at work, exercise, or smoking than BRFSS participants and were less likely to consume more fruits and vegetables. More research is needed to explore group differences in screening practices compared to modifiable health behaviors in daughters of mothers with breast cancer.
