Background/Objectives: Obesity and dental caries are significant health issues affecting children worldwide. This study aims to investigate the prevalence of obesity and dental caries among kindergarten children in Saudi Arabia during the early implementation years of the Vision 2030 initiative. Specifically, it examines the obesity rates between public and private kindergartens and assesses the correlation between obesity and caries risk. Methods: We conducted a cross-sectional study involving a stratified sample of 347 kindergarten children in Jeddah, Saudi Arabia, from September 2022 to March 2023, as part of a larger project assessing the obesity and dental caries prevalence in school-aged children. Their body mass index (BMI) was computed after their weight and height were measured. Following an oral examination, the decayed, missing, and filled teeth (dmft) scores were noted. The relationships between dmft and BMI, sex, and school type were studied using non-parametric tests, and its predictors were assessed as well. Results: Our findings indicate that 15.3% of the children were classified as obese based on the BMI measurements, while 9.8% were categorized as overweight. The prevalence of obesity did not show significant differences by school type when classified by BMI. The mean dmft score was 2.8 ± 3.6, with those children in public kindergartens demonstrating significantly higher dmft scores compared to their private counterparts (p < 0.001). Notably, there was no observed relationship between obesity and caries activity. Conclusions: Despite the implementation of Saudi Vision 2030, the high prevalence of obesity and dental caries among kindergarten children suggests that the current health initiatives may be insufficient. The lack of a relationship between obesity and caries activity highlights the complexity of these health issues and the need for targeted interventions. To improve the health outcomes, it is recommended to enhance the awareness campaigns regarding oral health and nutrition, increase access to preventive dental care, and integrate nutrition education into kindergarten curricula.

Saudi Vision 2030 was launched in 2016. Obesity and dental caries are both highly prevalent in Saudi adolescents and have been targeted by the Vision’s health initiatives. The aim is to assess their prevalence in adolescents during the first decade since the launch of the Vision. This cross-sectional study was conducted in Jeddah, Saudi Arabia using a stratified sample of 571 high school students, with an average age of 16.7 (0.6). Their height and weight were measured, and their body mass index (BMI) was calculated. The decayed, missed, and filled scores (DMFTs) were recorded after an oral examination. Non-parametric tests were used to assess the associations of DMFT with BMI, sex, and school type; and its predictors were assessed. One-third of males were overweight/obese compared with 22% of females. Males exhibited higher DMFTs than females. DMFTs were higher among public school students than among their private school counterparts. No significant association was observed between DMFT and BMI. Sex and school type were significant predictors of DMFT. The prevalence of obesity has slowly decreased in adolescents, but the prevalence of dental caries has not. There was no significant relationship between these conditions. Saudi Vision 2030’s current preventive/educational initiatives may be more effective in combating obesity than dental caries.
