Abstract

Background: About 29 million US adults are living with diabetes, a condition that can lead to many negative health outcomes, including poor physical function. Physical activity has been shown to decrease the risk for diabetes and improve physical function in adults as they age. The purpose of this review was to evaluate if physical activity interventions improve the physical function of older adults at risk for diabetes and identify intervention characteristics that might impact results.
Methods: The PubMed database was searched to identify publications of randomized clinical trials of physical activity interventions to impact physical function in older adults at risk for diabetes. Eligible studies included adults age ≥ 50 years with ≥ overweight, metabolic syndrome or pre-diabetes, and evaluated change in physical function (gait speed, strength, or the short performance physical battery test). The search was limited to English language articles, using the terms ‘physical activity’, ‘exercise’, ‘sedentary’, ‘physical function’, ‘gait speed’, ‘obesity’, ‘metabolic syndrome’, and ‘pre-diabetes’.
Results: Of the 140 studies that were identified from PubMed, 8 met eligibility criteria. One additional study was identified through the reference lists of eligible studies. Eight of 9 studies found significant improvements in physical function outcomes in the PA intervention vs control group. Interventions that included both aerobic and resistance training together resulted in better improvements in physical function than just aerobic or resistance training alone.
Conclusion: Increasing physical activity levels in this population has shown to improve physical function, which can potentially lead to increased independence, decreased healthcare costs, and improvements in quality of life for these adults as they age. These results indicate important findings for the public health of older adults at risk for diabetes.
