Integrative Review of Nurse-Delivered Physical Activity Interventions in Primary Care.

Promotion of physical activity has been a public health priority for decades. The purpose of this integrative review is to examine the effectiveness of nurse-delivered physical activity interventions conducted in primary care settings. Computerized database and ancestry search strategies located distinct intervention trials between 1990 and 2014. Nineteen national and international studies with 7,350 participants were reviewed. The most common intervention was physical activity counseling with supportive or motivational contacts. Few studies utilized exercise training, device-based exercise monitoring, or exercise prescriptions. The most common follow-up durations were 3 to 12 months. Half the studies integrated health behavior theoretical frameworks into the intervention. Almost 80% of the studies reported significant increases in walking, moderate or vigorous physical activity, or overall physical activity in the intervention groups. Interventions successful in increasing physical activity most often utilized tailored techniques such as providing "stage of change"-specific strategies or helping patients set individualized goals.
