Clinical Report: Assessment of Serum Vitamin D in Non-Obese Women with PCOS
Overview
This systematic review and meta-analysis evaluated serum vitamin D levels in non-obese women with polycystic ovary syndrome (PCOS). The findings indicate no significant differences in vitamin D concentrations between non-obese PCOS patients and healthy controls, suggesting that vitamin D deficiency may be more closely related to obesity than to PCOS itself.
Background
Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder affecting a significant portion of women globally, often associated with metabolic complications such as insulin resistance. Vitamin D is known to play a role in metabolic health and reproductive function, yet its specific impact on non-obese women with PCOS remains unclear. Understanding the relationship between vitamin D levels and PCOS is crucial for developing targeted interventions.
Data Highlights

Non-Obese PCOS Patients
Controls

Key Findings
No significant differences in serum 25(OH)D or 1,25(OH)2D levels between non-obese PCOS patients and controls.
Heterogeneity in results attributed to factors such as region, diagnostic criteria, BMI, and assay methods.
Significant publication bias detected in the included studies.
Vitamin D deficiency may be driven by obesity rather than PCOS pathogenesis.
Further prospective studies are needed to clarify the role of vitamin D in non-obese PCOS.
Clinical Implications
Clinicians should consider that vitamin D levels in non-obese women with PCOS may not differ significantly from those in healthy controls. This suggests that routine vitamin D supplementation may not be warranted for non-obese PCOS patients, and focus should be directed towards managing obesity-related metabolic issues.
Conclusion
The findings indicate that serum vitamin D concentrations are not significantly associated with non-obese PCOS, highlighting the need for further research to explore the implications of vitamin D in this population.
