Iranian children with overweight and obesity: an internet-based interventional study

A Comprehensive Review of School-Based Lifestyle Interventions to Reduce Childhood Obesity in the Eastern Mediterranean Region

Childhood obesity prevalence has increased worldwide and substantially in the 22 countries of the Eastern Mediterranean Region (EMRO). Weight-related interventions are urgently required in these countries to tackle childhood obesity and its related consequences. There has been no review to date of obese children in the Eastern Mediterranean Region. This review discusses the different school-based lifestyle interventions conducted among obese children in the EMRO and assesses the applicability of future programs in Saudi Arabia. A thorough search of the literature was conducted on PubMed. A total of 170 studies were found, and eight of them were included in this review. The included studies were all randomized controlled trials or quasi-experimental. This review article showed that school-based lifestyle interventions may reduce childhood obesity by integrating interactive learning about healthy diet and physical activity within a whole school approach, involving children and their parents, modifying the school environment, and facilitating a workshop on healthy food preparation. To motivate children to change their behavior, it is crucial to meet with parents in person and utilize technology and rewards. School-based lifestyle programs can lower childhood obesity by involving all relevant parties, such as families and schools, and using reliable instruments to track results to establish a healthy community. In order to confirm these findings, more research is required for a longer period of time, more than six months.

[Strategies and effects of digital interventions in overweight and obesity treatments in children and adolescents-a systematic review]

BACKGROUND

Rising obesity prevalence in childhood and adolescence are characterized by unhealthy lifestyles such as low physical activity due to high media use. Recent studies use the accessibility of this target group through digital media, whereby technologies represent new approaches in the intervention design of weight reduction. However, the question arises as to which digital combinations and methodological program concepts condition effective body mass index (BMI) changes.

AIM

To gain insights into effective program design and media use; digital intervention strategies for BMI reduction in overweight and obese children and adolescents will be analyzed and evaluated.

METHODS

A systematic review was conducted in the databases MEDLINE via PubMed, Science Direct, and Web of Science to analyze studies from 2016 to 2021 on changes in BMI and BMI z‑score of overweight and obese 6‑ to 18-year-olds. Methodological study quality was assessed according to the Cochrane Risk of Bias guidelines.

RESULTS

From 3974 studies, seven articles describing the use of fitness wristbands, smartphones, and computer-based programs were identified. All media achieved BMI reductions, with smartphone interventions via calls and messages causing the most significant changes.

DISCUSSION

Smartphones as providers of digital programs (e.g., apps) offer effective approaches to obesity reduction. Based on the data, the selection and combination of several media as well as the relevance of family involvement and the methodological foundation of the measures are confirmed. Due to the young age of the participants, media interventions must be made accessible to the target group.
