Effectiveness of Behavioral Interventions to Modify Physical Activity Behaviors in General Populations and Cancer Patients and Survivors

摘要

A majority of adults and over a third of children do not engage in adequate physical activity. Further, it has been suggested that exercise may have physiologic and psychological benefits for cancer survivors, from the point of diagnosis and through the balance of life. The objectives were to perform a systematic review of the literature to address: (1) What is the evidence that physical activity interventions alone, or combined with diet modification or smoking cessation, are effective in helping individuals sustainably increase their aerobic physical activity. (a)Is the effectiveness of theoretically based interventions different$ (b) Do hypothesized moderators affect the results of these interventions$ (c) Do these interventions affect theoretically hypothesized mediators$ (d) In these interventions, is there a relationship between changes in theoretically hypothesized mediators and changes in physical activity$ (2) What is the evidence that physical activity interventions, alone or combined with diet modification or smoking cessation, are effective in helping cancer survivors improve their psychosocial or physiological outcomes.
