Background

Mild cognitive impairment MCI represents a critical window to intervene against dementia. Exercise training is a promising intervention strategy, but the efficiency i.e., relationship of costs and consequences of such types of training remains unknown. Thus, we estimated the incremental cost-effectiveness of resistance training or aerobic training compared with balance and tone exercises in terms of changes in executive cognitive function among senior women with probable MCI.

Methods

Economic evaluation conducted concurrently with a six-month three arm randomized controlled trial including eighty-six community dwelling women aged 70 to 80 years living in Vancouver, Canada. Participants received twice-weekly resistance training n = 28, twice weekly aerobic training n = 30 or twice-weekly balance and tone control group classes n = 28 for 6 months. The primary outcome measure of the Exercise for Cognition and Everyday Living EXCEL study assessed executive cognitive function, a test of selective attention and conflict resolution i.e., Stroop Test. We collected healthcare resource utilization costs over six months.

Results

Based on the bootstrapped estimates from our base case analysis, we found that both the aerobic training and resistance training interventions were less costly than twice weekly balance and tone classes. Compared with the balance and tone group, the resistance-training group had significantly improved performance on the Stroop Test p = 0.04.

Conclusions

Resistance training and aerobic training result in health care cost saving and are more effective than balance and tone classes after only 6 months of intervention. Resistance training is a promising strategy to alter the trajectory of cognitive decline in seniors with MCI.
