Nutrition, Lifestyle and Health Outcomes in Older Adults

Dear Colleagues,

The global population is aging rapidly. The number of people aged 60 years and older has reached 1.1 billion, and by 2050, this number will have doubled, comprising 25% of the population in the world. This demographic shift emphasizes the need for focused research on the health and well-being of older adults. Older adults are more susceptible to chronic conditions such as cardiovascular diseases, diabetes, and cognitive decline. Nutrition and lifestyle choices play a critical role in the prevention and management of these conditions, and these are key determinants of the quality of life in older adults. Proper diet, physical activity, and social engagement can significantly enhance physical, mental, and emotional well-being, promoting healthy aging and independence. However, aging is often accompanied by physiological changes that affect nutrition (such as decreased appetite and digestive issues) and lifestyle (e.g., fewer physical activities), with malnutrition being a common concern in older adults, with this condition leading to frailty and a low body mass index (BMI). Therefore, the aim of this Special Issue is to both investigate how nutrition and lifestyle in older age affect health outcomes and address these challenges through research to improve health in older adults. Our Special Issue will publish papers that (1) investigate the determinants of nutrition and lifestyle in older adults, (2) explore the impacts of nutrition and lifestyle in older age on the risk of chronic diseases and quality of life, as well as the mechanisms of their impacts, (3) examine combined and interactive effects of nutrition and lifestyle on health outcomes in older populations, or (4) assess the impacts of nutrition and lifestyle on prognosis in older adults with chronic conditions.
