Daily pedometer steps among older men: Associations with health-related quality of life and psychosocial health

Abstract

Purpose. To determine the associations of daily pedometer steps with health-related quality of life (HRQoL) and psychosocial health. Design. Cross-sectional. Setting. Alberta, Canada. Subjects. Three hundred eighty-five older-aged men 55 years of age and older. Measures. Subjects completed a mailed survey that assessed HRQoL (RAND-12 Health Status Inventory [RAND-12]), depression, anxiety, and satisfaction with life. Steps/day were assessed with a pedometer via a 3-day step-monitoring period. Analysis. Average pedometer steps/d were categorized into quartiles (Qs). The primary model assessed the association between average pedometer steps/d as the independent variable of interest and our dependent variables of interest (physical, mental, and global health component scores of the RAND-12). Results. For HRQoL, all three adjusted models (i.e., physical, mental, and global health) indicated a significant linear trend between HRQoL indices across pedometer step Qs, with participants in Q3 and Q4 demonstrating higher physical, mental, and global health compared to participants in the lowest Q of pedometer steps (Q1) (all p
