Effectiveness of game-based exercise interventions on modifiable cardiovascular risk factors of individuals with type two diabetes mellitus: A systematic review and meta-analysis.

Background: Sedentary lifestyles have been identified as a major risk factor for cardiovascular complications for individuals with type 2 diabetes mellitus (T2DM). Using video-gaming components, game-based exercise interventions can encourage these individuals to engage in regular physical activity (PA), given their favorable interactive interfaces, feedback, and on-demand flow experiences.

Aim: To evaluate the effectiveness of game-based exercise interventions, on modifiable cardiovascular risk factors, quality of life, and PA levels among individuals with T2DM.

Methods: Published and unpublished studies were retrieved from eight electronic databases and reference lists of the included studies. Articles included in this study were from the inception of the databases to January 2022. Two reviewers performed screening, quality appraisal, and data extraction independently. Meta-analyses were conducted for the primary and secondary outcomes through RevMan. The protocol was registered on PROSPERO (CRD42022298894).

Results: Of the 11 selected studies involving 1045 individuals of both genders with T2DM, 9 were included in the meta-analyses for glycosylated hemoglobin, blood pressure (BP), low-density lipoprotein cholesterol, quality of life, and physical activity levels. The meta-analyses reported very small to large effect sizes favoring game-based exercise interventions. Large effect sizes were reported for systolic BP, diastolic BP, and quality of life measured through SF-12 Mental Component Summary scores.

Linking evidence to action: Game-based exercise interventions may improve modifiable cardiovascular risk factors, quality of life, and PA levels among individuals with T2DM. Supervision, PA levels, or motivation can affect the effectiveness of game-based exercise interventions.
