Background: Most studies that estimate the occurrence of childhood stroke use heterogeneous methods and rely on International Classification of Diseases codes, a strategy that may be unreliable.Purpose: This study aimed to estimate the occurrence of childhood stroke in Indonesia using imaging and clinical data from a private hospital network. Methods: This cross-sectional study used consecutive retrospective multicenter data samples collected in 2019– 2023. The study cohort included children aged >28 days to young adults aged 24 years with confirmed ischemic or hemorrhagic stroke on computed tomography (CT) or magnetic resonance imaging (MRI). The 1-year occurrence was calculated, and the data analysis was performed using IBM SPSS Statistics ver. 26.0. Results: Over 5 years, the performance of 8,987 CT and 6,133 MRI scans resulted in the identification of 1,074 stroke cases. The average patient age was 14.8±7.0 years. Stroke occurrence was highest in 2021 (9.08%) and lowest in 2022 (5.91%). Male patients accounted for 67.9% of cases, with hemorrhagic strokes accounting for 83.4% of the total, primarily resulting from accidents (73.2%) and predominantly occurring in the frontal region (37.1%). A significant majority of cases (66.7%) were reported in Java. Males had a relative risk of 1.93 (95% confidence interval, 1.48–2.52; P<0.001) for hemorrhagic stroke versus females. Conclusion The incidence of childhood stroke revealed critical epidemiological trends and disparities, emphasizing the need for targeted public health interventions and enhanced stroke prevention strategies in Indonesia.

Purpose: This study aimed to describe the prevalence of vitamin D deficiency in Indonesian children and adolescents. Methods: This was a meta-analysis of prevalence using the Hartung-Knapp-Sidik-Jonkman method with a random effects model. A prediction interval was used to estimate true effects. We searched PubMed, MEDLINE, Cochrane Library, Science Direct, Google Scholar, and 3 Indonesian databases (Indonesian Scientific Journal Database, Neliti, and Indonesia One Search). We included cross-sectional or case-control studies that provided data on the prevalence of vitamin D deficiency. We excluded case reports, case series, cohort studies, or studies outside Indonesia. We computed point prevalence by dividing the number of children with hypovitaminosis D by the total number of subjects in that study. This review was registered with PROSPERO (International Prospective Register of Systematic Reviews) (CRD42022329814). Results: Of 1,397 manuscripts identified, 7 were included in this review. A total of 5,870 children were included in this meta-analysis, ranging in age from 6 months to 19 years. The prevalence of hypovitaminosis D in Indonesia was calculated as 33% (95% confidence interval [CI], 9–56) and was higher in females (60% [95% CI, 58–62]) than in males (40% [95% CI, 38–42]). Mean serum vitamin D level was 22.74 ng/mL (95% CI, 16.95–30.51) with a prediction interval of 15.96 ng/mL to 29.52 ng/mL. Conclusion Vitamin D deficiency is a public health emergency in Indonesia. Strategies to detect and treat vitamin D deficiency in Indonesian children and adolescents should be implemented immediately.
