Special Issue Information

Dear Colleagues,

In an aging of the world, various changes will occur in lifestyle behavior in daily life. In particular, nutritional problems cause weight loss due to reductions in energy intake against the backdrop of various factors. Reductions in energy consumption due to a decrease in physical activity and an increase in sedentary behavior, and the associated decline in physical fitness and motor function that comes with this, induce the onset of frailty, which leads to cognitive decline and the onset of dementia. In this Special Issue, in addition to the involvement of nutrition and physical activity in the onset of frailty and cognitive decline, we focus on lifestyle factors as contributors to improvement and summarize the latest scientific findings. Specifically, the following contents are included:

  • Frailty, cognitive function, and lifestyle factors such as nutrition, physical activity, and sedentary behavior in the elderly, and proposals for health issues that need to be addressed;
  • The involvement and mechanisms of nutrition, physical activity, and sedentary behavior as factors in the development of frailty and cognitive decline;
  • The prevention and improvement of frailty and cognitive decline through nutrition and physical activity interventions, and their mechanisms.
