Objective The aim of this meta-analysis is to estimate the increased risk of Vitamin D Deficiency (VDD) associated with non-ambulatory status (Gross Motor Function Classification System [GMFCS] Levels IV-V) compared to ambulatory status (GMFCS Levels I-III) to estimate evidence-based screening protocols.

Background Vitamin D deficiency significantly compromises bone health and motor function in Cerebral Palsy (CP), yet a unified risk quantification for the most severely affected children has been lacking. Establishing this quantification is essential to guide standardized screening practices.

Design/Methods We conducted a random-effects meta-analysis of observational studies that reported serum 25(OH)D levels and GMFCS classification in children with cerebral palsy aged 0-18 years. Vitamin D deficiency was typically defined using 25(OH)D cutoffs below 20 ng/ml. Six studies (N=676 CP patients) were included, with four contributing 2×2 count data for the primary analysis. The Risk of bias was evaluated using Newcastle-Ottawa Scale (NOS).

Results The pooled analysis demonstrated a strong and consistent association between severe motor impairment and VDD risk. Non-ambulatory children (GMFCS IV-V) had 2.62 times greater odds of Vitamin D deficiency compared to those who were ambulatory (OR = 2.62; 95% CI : 1.38, 4.98). We observed considerable variability across the studies (I²= 59.8%). A Sensitivity analysis excluding one outlier study confirmed that the association remained significant (OR of 3.21; 95% CI : 1.87, 5.51) with lower heterogeneity (I² = 44.9%). The median Newcastle-Ottawa Scale score was 6 of 9, indicating moderate risk of bias.

Conclusions Non-ambulatory status (GMFCS IV-V) is a major risk factor for vitamin D deficiency in children with cerebral palsy. These findings highlight the need to include routine vitamin D screening and prophylactic supplementation in non-ambulatory pediatric CP care.
