Racial, Ethnic, and Socioeconomic Disparities in Meeting Physical Activity Guidelines among Female Breast Cancer Survivors in the United States

Menée aux Etats-Unis à partir de données portant sur 5 845 patientes ayant survécu à un cancer du sein et sur 160 162 témoins, cette étude analyse leur adhésion aux recommandations concernant la pratique d'une activité physique en fonction de critères ethniques et socioéconomiques

Résumé en anglais

Cancer survivors show low physical activity participation rates in the United States. However, there are limited national-level data on disparities in the prevalence of meeting physical activity guidelines among women with and without breast cancer. We aimed to evaluate national-level trends in meeting physical activity guidelines across demographic and socioeconomic characteristics of breast cancer survivors and women without cancer.Data for women ≥35 years of age with and without breast cancer were obtained from the 2004 to 2018 National Health Interview Survey. We used National Health Interview Survey sample weights to generate national-level prevalence estimates and calculate absolute and relative indices of disparity for breast cancer survivors and women without cancer meeting aerobic (150 minutes/week) and muscle-strengthening guidelines (2 sessions/week) stratified by demographic (e.g., race/ethnicity) and socioeconomic (e.g., homeownership) characteristics.We included 5,845 breast cancer survivors and 160,162 women without cancer. The weighted percentage of breast cancer survivors meeting aerobic guidelines was 37.7% compared with 40.9% of women without cancer. Fewer women met muscle-strengthening guidelines. There were lower proportions of women who were younger (<50-years), were non-Hispanic Black, were Hispanic, worked 35+ hours/week, or rented their home among breast cancer survivors meeting aerobic guidelines compared with women without cancer meeting aerobic guidelines.Breast cancer survivors were less likely to meet physical activity guidelines compared with women without cancer. Demographic and socioeconomic disparities may exist among breast cancer survivors and women without cancer meeting physical activity guidelines.Targeted interventions may be necessary to address low physical activity participation among breast cancer survivors.
