[The efficacy of e-health management on weight control in adolescents: a systematic review].

Background: Advances during the past decade have made it feasible to apply e-health methods to chronic disease management. Researchers have recently begun applying these methods to weight control. The application of e-health management methods to weight control in adolescents has yet to be investigated empirically.

Purpose: This study conducted a systematic review of reports discussing the weight-control effects of e-health management in adolescents.

Methods: Researchers searched 6 electronic databases for relevant articles published between 1995 and April 2013. Data were collected using inclusion and exclusion criteria. A modified Jadad Scale was used to evaluate the quality of the identified articles.

Results: Seven studies met the inclusion criterion of targeting adolescent subject populations. A total of 3728 adolescents and 1394 parents participated in these studies. The majority of participants were overweight girls and median participant ages ranged from 12.52 (SD = 3.15) to 15.31 (SD = 0.69). All studies reported that e-health management reduced body mass index and body fat percentage. Four studies indicate that e-health management may improve physical activity knowledge and skills. However, diet control outcomes among the seven studies varied.

Conclusions: Empirical results demonstrate that e-health management significantly affects weight control. However, the effectiveness of log-in versus primary outcome indicators was inconclusive. Future studies should consider the use of incentives, reminder systems, and other strategies to enhance website usage. The development of an Internet-based, computer-tailored weight-management intervention for overweight adolescents and the development of an appropriate care model are recommended.
