ABSTRACT
Vitamin D deficiency is a globally recognized health concern, with particular prominence in specific geographies and demographics. Saudi Arabia, with its unique climatic conditions and cultural practices, has been under scrutiny regarding the prevalence of this deficiency, especially among children and adolescents. This systematic review aimed to assess the prevalence of vitamin D deficiency among children and adolescents in Saudi Arabia by compiling and analyzing various studies to offer a comprehensive view of the situation. The comprehensive web search encompassed a range of databases, including Google Scholar and PubMed, to gather studies published between 2012 and 2023. An analysis was conducted on seven studies, totaling 2,429 participants, with each study focusing on various aspects, regions, and cohorts within Saudi Arabia. These studies employed different methodologies, ranging from cross-sectional surveys to randomized clinical trials. The review unveiled an alarming prevalence of vitamin D deficiency in the studied population. On average, around 81.1% of children and adolescents showcased inadequate vitamin D levels. Specific vulnerable groups, such as those with Type 1 diabetes mellitus or asthma, had pronounced deficiencies. Factors influencing these levels ranged from dietary habits, sun exposure, physical activity, and socioeconomic parameters. The compelling evidence from the studies underscores a consistent health issue among the pediatric population in Saudi Arabia that the overwhelming majority of Saudi children and adolescents lack adequate vitamin D. Addressing this widespread deficiency needs a multifaceted approach. Implementing policies that support vitamin D food fortification, encouraging routine screenings, and launching public awareness campaigns about safe sun exposure and diet can play a transformative role in this health crisis.
