Nutritional Status and Zinc Serum Concentration in Subjects with Bone Fracture

Background and Objectives: Bone fracture is known as a major health problem today and animal studies have shown that zinc deficiency results in reduced bone growth, bone volume and force required for breaking .accordingly this study was designed to assess nutritional status, serum zinc concentration and serum alkaline phosphatase as an enzyme that is dependent on zinc and needed for bone modelingʹ in patients with bone fracture. Material And Methodes: This analytical cross-sectional study, were conducted on 71 patients with traumatic long bone fracture referred to shohada hospital of Tabriz. Nutritional intake was determined by using 3 day food rccords,physical activity-individual and clinical information by questionnaire and weight and height of subjects were measured by scale. Serum zinc concentration was measured by atomic absorption spectrophotometer and serum alkaline phosphatase by using pars azernoon kit. data were analyzed by using analytical and descriptive statistical methods. Results: Of total 71 patients 47 people were male and 24 female. Mean energy and dietary zinc intake were 2385 kcal and 4.82 rug/day, respectively, that meet only 54ʹ1ʹ0 and 43.5% of zinc RDA in female and male respectively, that was significantly lower than dietary recommendation ....ʹalues. Mean serum zinc concentration in this patients was lower than normal values and was significant but serum alkaline phosphatase was in normal range. dietary zinc intake was correlated with dietary intake of protein, fat, calcium, phosphor and magnesium, significantly. however Zinc serum hadnʹt significant correlation with age, BMI, smoking status and serum alkaline phosphatase concentration and dietary zinc. Conclusion: Based the finding of this study, nutritional status and serum zinc concentration in patients with trumatic bone fractures were lower than normal range.thcrcrfore nutritional education to intake of zinc rich foods with calcium and high intake of these food when bone fracrure happened to improve for fracture healing, is suggested.
