Factors That Influence Physical Activity Behavior in Children and Adolescents During and After Cancer Treatment: A Qualitative Systematic Review of the Literature.

Purpose: The aim of this systematic review is to reveal the social, personal, and contextual factors that influence physical activity (PA) in children and adolescents during and after cancer treatment.

Method: SPORTDiscus, Cochrane, Web of Science, PubMed, and FIS Education electronic database were systematically searched.

Results: The 13 included studies show that social support (parents, siblings, and friends) in particular is rated as important by cancer survivors; for example, doing PA together. Depending on the treatment status and state of health, particularities arise. During the acute treatment phase, parents issued more prohibitions regarding PA than after treatment. The state of health and concern about infections are described as inhibiting factors. Not all hospitals generally offer special exercise programs for cancer patients, and in some cases, only sporadic exercise sessions were conducted by specialized staff. In addition, the hospital atmosphere, such as cramped rooms, tends to be associated with demotivating effects.

Conclusions: Both inhibiting and promoting factors in the area of social, personal, and contextual factors could be identified. The most fundamental factor for PA is the physical condition. Social factors, such as parents or friends, often have a motivating effect and can promote PA. Inhibiting factors are mainly context-related, such as an environment unsuitable for PA. Although the review highlights interesting aspects, further treatment-related and longitudinal studies could provide deeper insights.
