Objective: To examine whether a testosterone and a high calorie nutritional supplement intervention can reduce frailty scores in undernourished older people using multiple frailty tools. Design: Randomized controlled trial. Setting/Participants: 53 community-dwelling, undernourished men and women aged >65 years from South Australia, Victoria and New South Wales. Intervention: Intervention group received oral testosterone undecanoate and a high calorie supplement (2108-2416 kJ/day) whereas the control group received placebo testosterone and low calorie supplement (142-191 kJ/day). Measurements: Frailty was operationalized using three frailty indices (FI-lab, FI-self-report, FI-combined) and the frailty phenotype. Results: There were no significant differences in changes in frailty scores at either 6 or 12 months follow up between the two treatment groups for all scales. Participants at the intervention group were 4.8 times more likely to improve their FI-combined score at both time points compared to the placebo group. Conclusion: A testosterone and a high calorie nutritional supplement intervention did not improve the frailty levels of under-nourished older people. Even so, when frailty was measured using a frailty index combining self-reported and lab data we found that participants who received the intervention were more likely to show persistent improvement in their frailty scores.
