Abstract Body:
Purpose/Background: The purpose of our study was to determine whether multi-lifestyle factors predict mammography screening in U.S. women. It is well established that several lifestyle factors, including physical activity, alcohol intake, smoking, BMI, and dietary factors, influence breast cancer risk. However, the link between these factors and mammography screening remain unclear. Moreover, multi-factor lifestyle approach may be more informative than looking at an individual factor at a time. Methods: Women aged 50-75 years who were non-adherent to breast cancer screening guidelines (n=858) were enrolled in an intervention study to promote adherence. Medical records were obtained at 6 months post intervention to verify screening. The women were surveyed at baseline and provided information on their lifestyle factors. The factors vegetable intake, physical activity, smoking, BMI, and alcohol intake were combined into a multi-factor lifestyle index. The index scores were based on CDC guidelines, and the scores ranged from 0-20. Binary logistic regression was used to estimate multivariable-adjusted odds ratios (OR) and 95% confidence intervals (CI). Results: The mean score for the multi-lifestyle index was 11.54. Overall, increase in multi- lifestyle index score predicted mammography adherence [OR = 1.05 (1.00 — 1.10)]. However, the association was stronger among subjects who received a doctor’s recommendation for mammography [OR = 1.10 (1.04 — 1.18)], while no association was observed among those without a doctor’s recommendation [OR = 0.97 (0.90 — 1.06)]. When assessing the association of single lifestyle factors, non-smoking [OR = 1.12 (1.00 — 1.26)] and increase in physical activity [OR = 1.16 (1.04 — 1.31)] significantly predicted mammography screening. Other lifestyle factors did not predict mammography adherence. Conclusion: Women who engaged in a healthier behavioral lifestyle were more likely to be screened for breast cancer, especially if they received a physician recommendation for breast cancer screening. These findings suggest that improved multi-lifestyle factors and efforts to increase patient-physician communication regarding breast cancer screening may increase mammography adherence to among U.S. women.
