[Physical inactivity behavior: is this an adaptive answer that is normal and inappropriate to public health in the 21st century?].

Physical inactivity or sedentary behavior is more and more widespread, a fairly recent worldwide health phenomenon. It currently takes the shape of a chronic illness with dire consequences. Its factors are influenced by personal motivation and the social and physical environments in which people live. Screening for physical inactivity or sedentary behavior enables patients and caregivers to become fully aware of its risks. The health benefits of simply adding walking to our everyday activities or adding low-impact movement in oureveryday lives would improve the health, the quality of life and longevity for most adults. Caregivers can successfully assist patients in changing their behavior. For certain patients suffering from diseases or complex cases, interdisciplinary specialized surveillance care is useful. There is a need to put this issue at the forefront of public health and adopt a positive stance towards strategies in our places of work, our schools, our means of transportation and overall urban planning and development.
