title: Lifestyle factors related to mortality and survival: a mini-review.
abstract: As the world's population ages, elderly people are becoming an increasingly important group that merits special attention with regard to health and social issues. Lifestyles affect health and survival at all ages, but the consequences of poor lifestyle behaviors may be different for elderly people than for younger adults. They can also be heavily dependent on exposure earlier in life. Our current state of knowledge is based predominantly on studies conducted among middle-aged adults or young elderly people. Moreover, studies are sparse throughout the entire older age spectrum, from 65 to 90 years. This article summarizes the evidence regarding the impact of lifestyle behaviors on mortality among elderly people. It focuses on behaviors modifiable by individual actions and public health interventions, such as smoking, obesity and sedentary behavior, which predispose numerous people to diseases that rank among the leading causes of death, including heart disease, cancer, stroke, diabetes and dementia. These factors not only shorten life but, when they occur together, also have a major impact on survival beyond that associated with each single lifestyle factor. We propose an integrated life course model to guide research on longevity to answer questions that remain open and to find new strategies to ensure a longer and healthier life for future generations.
