Comprehensive analysis of vitamin d deficiency in elderly patients, children, and postmenopausal women: Insights from Mohammed VI university hospital Oujda

This comprehensive paper amalgamates findings from three extensive studies conducted at Mohammed VI University Hospital Oujda, which examine the prevalence and predictors of vitamin D deficiency across different demographic groups: elderly patients, children, and postmenopausal women. The studies, covering a period of 92 months, retrospectively analyzed serum 25(OH)D concentrations to reveal a significant prevalence of vitamin D deficiency in all three populations. The findings underscore the critical need for routine monitoring and interventions to mitigate the associated health risks.
