Abstract

Purpose

To establish the effect of a long-term multicomponent exercise (LTMEX) intervention (24 months) on health-related quality of life (HRQoL), in older adults with type 2 diabetes (T2D).


Methods

This longitudinal retrospective cohort study analyzes the effects of a supervised LTMEX program on HRQoL in older adults with T2D (n = 279). Participants underwent one of two conditions: LTMEX (n = 241) trained three times per week; and unchanged lifestyle—the control group (CO; n = 38). Participants completed baseline, and 2-year follow-up evaluations including the Short Form Health Survey 36 (SF-36), anthropometric, hemodynamic components, and cardiorespiratory fitness (VO2 peak).


Results

LTMEX improves HRQoL, specifically physical functioning (P < 0.001), general health (P < 0.05), vitality (P < 0.001), mental health (MH; P < 0.05), physical component score (P < 0.001), mental component score (P < 0.001), and total SF-36 (P < 0.001). LTMEX group also decreased body weight (BW; P < 0.005), waist circumference (WC; P < 0.001), waist-to-hip ratio (WHR; P < 0.001), and systolic blood pressure (SBP; P < 0.001), and increased VO2 peak (P < 0.001). CO group increased WC (P = 0.012), BMI (P = 0.024), waist-to-hip ratio (WHR; P = 0.003) and SBP (P < 0.001), and decreased vitality (P < 0.001) and MH (P < 0.05).


Conclusions

A LTMEX intervention improves physical and mental HRQoL in older adults with T2D, and also anthropometric, hemodynamic profile, and cardiorespiratory fitness.
