Assessing the Predictive Value of Serum Vitamin D Levels for Hip Fracture Risk in Older Adults and Identifying Associated Risk Factors
Abstract
Background As the elderly population continues to grow globally, the incidence of hip fractures among this demographic is becoming an increasingly pressing public health issue. Hip fractures often result from a complex interplay of factors, including sociodemographic variables, clinical comorbidities, medication use, physical activity, and vitamin D levels. Understanding these factors is essential to mitigating the risk of hip fractures in older individuals. Objective This study aims to explore the relationship between vitamin D levels and hip fracture risk in elderly patients, identifying the clinical, demographic, and environmental factors contributing to fracture risk, with a particular focus on the role of vitamin D in bone health. Methodology This cross-sectional observational study was conducted at Mardan Medical Complex between January 2024 and February 2025. A total of 119 older adult patients (aged 50 years and above) with confirmed hip fractures were included. Demographic data, comorbidities, vitamin D levels, and relevant biomarkers were collected. Serum 25-hydroxyvitamin D [25(OH)D] levels were measured using electrochemiluminescence immunoassay. Statistical analysis, including ANOVA, Mann-Whitney U tests, and decision tree modeling, was employed to assess the relationship between vitamin D and other variables, including BMI, mobility, supplementation, and comorbidities. Results The study found a high prevalence of vitamin D deficiency among older adult patients…
