Navigating airports: a scoping review of physical access challenges and experiences for persons with disabilities.

In this study, we conducted a questionnaire-based survey on the daily lifestyle habits of male workers in a company, aiming to determine the association between lifestyle habits and indicators of sarcopenia. Japan is currently experiencing a decline in its total population, along with an increase in the aging population. Moreover, an increase in the incidence of lifestyle-related diseases among adults and older adults have been noted, leading to rising medical costs and an insufficient balance in the working population. Obesity and reduced muscle mass/strength are worsened by reduced physical activity, further increasing the risk of lifestyle-related diseases and the need for long-term care. For these reasons, prevention of lifestyle-related diseases and long-term care are important. To achieve this, preventing obesity and maintaining/increasing muscle mass and strength by improving lifestyle habits early are thought to lead to disease prevention and an extension of healthy life expectancy. Skeletal muscle mass begins to decrease in the 30s, and 30−40% of the muscle mass of a person in their 20s is approximately lost by the age of 80. Sarcopenia refers to a significant loss of skeletal muscle mass and is considered an important factor leading to the requirement for nursing care because of a decline in activity. Sarcopenia diagnostic criteria for Asians uses handgrip strength measurement (muscle strength) or a chair-stand test (physical function) based on the Asian Working Group for Sarcopenia 2019 (AWGS 2019) guidelines; individuals with a score below the standard are suspected to have sarcopenia.
