    Abstract

    Background: The objective was to investigate the longitudinal relationship between physical activity and health-related quality of life (HRQL) in adults with type 2 diabetes. Methods: Data were from a prospective cohort of adults with type 2 diabetes. Weekly moderate-to-vigorous physical activity (MVPA) was reported using the Godin Leisure-Time Physical Activity Questionnaire, and HRQL was reported using the SF-12 and 5-level EQ-5D. Participants were categorized based on current weekly MVPA recommendations. Multivariable linear regression was used to explore associations between MVPA and HRQL, and multinomial logistic regression was used to assess the direction of change in HRQL after 1 year. Results: Mean age of participants (N = 1948) was 64.5 ± 10.8 years and 45% were female. Participants reported a mean of 84.1 ± 172.4 min of MVPA/week, and 21% (n = 416) met weekly MVPA recommendations. MVPA was associated with differences in the physical functioning (b = 5.42; P < .001), general health (b = 2.45; P = .037), and vitality (b = 2.83; P = .016) SF-12 dimensions. Participants who met recommendations were less likely to report a decline (vs. no change) in EQ-5D index score (OR = 0.75; 95% CI [0.57, 0.99]), and SF-12 physical component summary (OR = 0.67; 95% CI [0.50, 0.90]), compared with participants not meeting recommendations. Conclusions: Participants who met weekly MVPA recommendations reported better physical functioning and were more likely to maintain their physical and overall HRQL over time.
