Prevalence of Childhood Obesity Among Children and Adolescents in Saudi Arabia: A Systematic Review

Childhood obesity is a growing public health concern worldwide, with significant implications for long-term health outcomes. Thus, the aim of this study is to highlight the prevalence and trend of obesity among children and adolescents in Saudi Arabia over the last 24 years. This systematic review included participants aged 2 to 19 years without systemic disease, reporting the prevalence of obesity using the Centers for Disease Control and Prevention (CDC) classification and BMI calculation, from studies in English or Arabic published between January 2000 and April 2024. We conducted a comprehensive search across multiple databases including ProQuest, Google Scholar, ISI Web of Science, Embase via Ovid, and MEDLINE via Ovid, and reviewed references of included studies. Data were extracted and quality assessed independently by two authors, with any disagreements resolved through discussion with a third reviewer, using the Newcastle-Ottawa Scale modified for this study. This systematic review included 21 studies from Saudi Arabia, published between 2006 and 2023, with participants aged 2 to 19 years. The studies involved a total of 63,512 subjects. Among children, the prevalence of overweight ranged from 5% to 29%, while obesity ranged from 3.8% to 49.7%, classified using CDC criteria. Quality assessment rated 10 studies as Very Good, 10 as Good, and one as Unsatisfactory. The systematic review of childhood obesity prevalence in Saudi Arabia over the past 24 years highlights alarming trends and significant public health implications. Our analysis emphasizes an increase in obesity rates among children and adolescents, revealing a complex link of socioeconomic, cultural, and lifestyle factors contributing to this epidemic.
