MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Previous studies have shown that offspring of long-lived parents are not only likely to live longer but to also avoid major chronic diseases (e.g., coronary heart disease), have fewer chronic disease risk factors, and to have better cognitive and physical function in late life. However, few studies have examined parental longevity in relation to an overall measure of successful aging that included reaching old age free of both major diseases and disabilities.
The objective of our study was to determine if parental longevity predicted healthy aging, defined as survival to age 90 without any major age-related diseases (coronary heart disease, stroke, diabetes, cancer, or hip fracture) or physical limitations. The participants of our study were from the Women’s Health Initiative, a large, longitudinal study among postmenopausal women from the United States.
We observed that women whose mothers survived to at least age 90 years were 25% more likely to achieve healthy aging. We also observed that women whose fathers only lived to age 90 did not have increased likelihood of healthy aging. However, women whose mother and father both lived to age 90 were the most likely to achieve healthy aging.
