Feasibility, acceptability and efficacy of a pilot exercise physiology group service for older people with type 2 diabetes

Abstract

Background and objective Type 2 diabetes affects over half a million older Australians. Australian Medicare group exercise and education interventions can support older adults’ diabetes management. However, the feasibility and acceptability of accredited exercise physiologist (AEP)-delivered services are yet to be assessed. This study aimed to assess the feasibility, acceptability and preliminary efficacy of a Medicare type 2 diabetes group exercise and education intervention for older adults. Methods This study was a single-arm feasibility, acceptability and preliminary efficacy trial of an AEP-delivered type 2 diabetes group service for older adults with the condition. Participants attended the diabetes clinic once per week for eight weeks, through Medicare, for a group exercise and education session. Attendance, participation, enjoyment, suitability, usefulness and pre–post clinical health outcomes were assessed. Results The intervention was feasible and acceptable, with 40 participants (mean [±standard deviation] age 71.8±4.5 years [range 65–81 years]; 45% female) attending 87% of sessions. Almost all participants (97%) strongly agreed that the program was enjoyable. Participants also improved fitness and cardiometabolic health outcomes. Discussion More Australians should be referred to and attend Medicare-subsidised exercise physiologist-delivered group sessions. The potential for additional sessions to achieve greater physical activity engagement and diabetes self-management should be further investigated.
