Impact of diabetes on longevity and disability-free life expectancy among older South African adults: A prospective longitudinal analysis
Authors' conclusion
We find large and important decrements in disability-free aging for people with diabetes in South Africa. This finding should motivate efforts to strengthen prevention and treatment efforts for diabetes and its complications for older adults in this setting.
