Taken together, accumulated evidence on the cardiovascular health benefits of physical activity, combined with the physical activity/inactivity prevalence and trend data in children, adolescents, and adults, points to the urgent need for more effective individual/clinical and public health strategies designed to promote this health behavior beginning early in life and extending across the life course. The Centers for Disease Control and Prevention (CDC),8 consistent with selected recommendations from AHA,9 provides nurses and other healthcare providers with strategies that can be incorporated with ease in a variety of clinical settings. These recommendations include making physical activity a patient vital sign by ensuring that all healthcare professionals assess physical activity and discuss ways to make progress toward meeting the Physical Activity Guidelines for Americans.10 Relatedly, the AHA recently issued a statement that includes guidelines for assessment of physical activity applicable for providers in a variety of settings.9 Emphasis is placed on dimensions (the mode, frequency, duration and intensity of activity) and domains (occupational, domestic, transportation, leisure time) of physical activity assessment. Available to all healthcare providers, the statement also provides a valuable decision matrix guide to selecting a physical activity measurement based on patient, provider, and contextual factors as well as the purpose(s) of the assessment.9
