Abstract

Novel approaches, such as exergaming, the utilization of video games that promote physical activity, have been proposed as potential solutions for the prevention and treatment of childhood obesity, a severe public health concern. However, exercise activities have not been demonstrated to be effective. This meta-analysis was designed to evaluate the effectiveness of exergaming in obesity-related outcome measure variables, including body mass index (BMI), body fat percentage, energy expenditure, and weight management, in both prevention and treatment settings. Exergaming was assessed for obesity prevention in seven studies, which included 653 participants, and for treatment in six studies, which included 248 participants. Research was categorized accordingly. Outcomes included BMI, body fat percentage, energy expenditure, and weight loss, and effect sizes were aggregated using fixed- or random-effects models based on the level of heterogeneity. In comparison to health education or no intervention, exergaming did not have a significant impact on BMI for obesity prevention. Weight control, energy expenditure, and percentage of body fat did not exhibit any significant differences. In comparison to no intervention, exergaming significantly reduced BMI, percentage of body fat, and weight among individuals with obesity. No significant differences were observed when exergaming was contrasted with traditional/non-structured exercise. Exergaming appears to be an ineffective obesity prevention tool for high-risk children; however, it is a promising treatment for obese children. In the treatment setting, exergaming led to substantially greater reductions in BMI, body fat, and weight loss. Nevertheless, the results of exergaming were comparable to those of conventional exercise.
