Cognitive Functioning and Health in Hispanic/Latina Breast Cancer Survivors

Abstract

We examined the effect of waist-to-hip ratio, body mass index (BMI), diet, and physical activity on cognitive functioning among Hispanic/Latina breast cancer survivors in a cross-sectional design study. Participants were 54 Hispanic/Latina breast cancer survivors and completed the NIH Toolbox Cognition Battery. Linear Regression Models tested if statistically significant correlations held with covariates. After controlling for covariates, moderate and hard physical activity were not associated with cognition. However, very hard physical activity was positively associated with faster processing speed (β = 0.56, p < 0.001) and composite cognition score (β = 0.36, p < 0.05). Total time (minutes) of moderate to very hard physical activity was positively associated with cognitive flexibility (β = 0.52, p < 0.001). Total caloric intake was positively associated with episodic memory (β = 0.35 p < 0.05). BMI and WHR were not associated with cognition. These findings showed positive association with engagement in more MVPA and harder intensity physical activity to better cognitive functioning among Hispanic/Latina breast cancer survivors.ClinicalTrials.gov NCT02780271.
