[Prevention in older age : key factors].

The extended life expectancy questions the quality of life of these additional years: with or without disability ? A review of the literature gives us some tips on preventive measures to maintain good health at an advanced age. Engaging in regular and moderate physical activity (such as walking) offers a range of health benefits, including reduced risk of all-cause mortality, lower risk for various diseases (ischemic stroke, ischemic heart disease, diabetes, breast and colon cancer), prevention of falls and functional decline in seniors living at home. Maintaining a healthy lifestyle (non-smoking, low alcohol consumption, adequate nutrition) as well as up-to-date immunization status and vitamin D supplementation in the deficient or vulnerable population, are factors that contribute to a better health in the last years of life.
