People who had four or five healthy lifestyle factors -- spanning diet, cognitive activity, physical exercise, smoking, and alcohol patterns -- at age 65 lived longer than their counterparts with zero or one healthy factors, according to Klodian Dhana, MD, PhD, of Rush University Medical Center in Chicago, and colleagues. Women added 3.1 years of life, while men added 5.7 years.
Of their total life expectancy at age 65, women with four or five healthy factors spent 10.8% of their remaining years with Alzheimer's dementia, while women with zero or one factors spent 19.3%, they reported. Men with four or five healthy factors spent 6.1% of their remaining life with dementia, while those with zero or one spent 12%.
