The aim is estimate and analyze the disability-free life expectancy (DFLE) among the Brazilian elderly by sex consider the body mass index (BMI) and smoking, alcohol consumption. The DFLE in elderly underweight (BMI <23 kg/m²), normal ( 23=BMI<28), overweight (28=BMI<30), obese (BMI=30), smoking status and alcohol was calculated using the Sullivan Method and the prevalence was estimated from data collected in 2013 through the National Health Survey (PNS). Overweight and obesity has a large effect on DFLE. Women overweight and obese live longer with disability than men. There is a higher prevalence of older women with obesity, approximately 30%. In the case of men, smoking decreases the years free of functional disability. Average time without disability for 60 years old men was 16.8 years compare to 23.4 in women with the same age. Healthy behavior is associated with survival and how the elderly live the remaining years of life.
