Social and environmental factors can be used as predictors for health conditions, functional and cognitive autonomy, wellbeing and satisfaction on older ages. Reduced incomes, low educational level, situation of loneliness, can also be pointed as predictive factors of a major and premature deterioration of health. The adaptation of social structures must be a priority for all ageing societies. Portugal will also have to find answers to these challenges. The main objective of this study is to understand the process of vulnerability and multiple dependency situations caused by changes in the Portuguese demographic structure, manly regarding old people, as concerns the following aspects: a) levels of well-being in ageing regions determined by a statistical indicator; b) specific health care and long-term care. %K Portugal %K ageing %K health policies %K regional and social diversity %U http://dx.doi.org/10.3384/hygiea.1403-8668.1091397
