Abstract
Physicalinactivity has been a public health problem worldwide for more than a decade. Of those who are physically active, a substantial percentage engage solely in low or very low physical activity (PA) levels. In the last 3 decades, the prevalence of PA in the United States has decreased with approximately 80% of adults not meeting the recommended guidelines for aerobic and muscle strengthening PA. The PA levels of youth have dramatically decreased with 85% of adolescents reporting no PA. Regular PA participation can aid in preventing chronic diseases. A strong inverse dose-response relationship exists between PA and the incidence of cardiovascular disease, all-cause and cardiovascular mortality. Moreover, low cardiorespiratory fitness levels are a risk factor for cardiovascular diseases: the leading cause of death and disability globally. Conversely, high amounts of moderate-to-vigorous intensity PA at levels 3-5 times recommended in guidelines reduce risk for all cause mortality. Socio-ecological determinants of PA are essential considerations for promoting across the life course. In health care and community settings, public health nurses have opportunities to promote PA through a socio-ecological approach across the life course of individuals and diverse populations.
