Title
Sustained gains from a diabetes prevention program and the role of telephone support
Background An evaluation of the sustainability of lifestyle changes was undertaken for participants completing a 12 month diabetes prevention program. This second part of the study also tested whether regular structured telephone calls could be effective in maintaining lifestyle changes.
Methods Originally, 237 participants completed a 12 month group-based lifestyle intervention study. They were aged 40–75 years, with a moderate to high risk of developing type 2 diabetes. Participants were then randomised to telephone support (n = 107) or self-care only (n = 98) for 18 months, and re-assessed using anthropometric, clinical, psychological and general health measures.
Results A total of 164 participants (85 telephone support and 79 self-care only) completed the follow-up. Changes between 12 and 30 months for the telephone support group were not significantly different from those found in the self-care only group. Beneficial lifestyle changes achieved by participants were generally sustained after the diabetes prevention program, with the exception of fasting plasma glucose and some psychological measures.
Conclusions Positive outcomes achieved at 12 months were generally maintained after a further 18 months. Telephone support did not appear to produce additional benefits.
