The effectiveness of self-guided web-based physical activity interventions among patients with a chronic disease: a systematic review.

Background: Despite well-documented health benefits, adults with a physical chronic condition do not meet the recommended physical activity (PA) guidelines. Therefore, secondary prevention programs focusing on PA are needed. Web-based interventions have shown promise in the promotion of PA behavior change. We conducted a systematic review to summarize the evidence about the effectiveness of web-based PA interventions in adults with chronic disease.
Methods: Articles were included if they evaluated a web-based PA intervention and used a randomized design. Moreover, studies were eligible for inclusion if they used a non- or minimal-treatment control group and if PA outcomes measures were applied. Seven articles were included.
Results: Three high-quality studies were statistically significant to the control group, whereas 2 high- and 2 low-quality studies reported nonsignificant findings.
Conclusion: Our best evidence synthesis revealed that there is conflicting evidence on the effectiveness of web-based PA interventions in patients with a chronic disease.
