Assesment of serum magnesium level in postmenopausal women with osteoporosis

This study was designed to assess nutritional and biochemicalfactor of magnesium in postmenopausal osteoporotic women. Materials AND METHODES: The population of this analytical crosssectionalstudy, was 60 postmenopausal osteoporotic women, referred torheumateology clinic of Tabriz. Nutritional intake was determined by 3 dayfood recall and food frequency questionnaire، individual and clinicalinformation by questionnaire and weight and height of subjects weremeasured by scale. Serum magnesium concentration was measured byatomic absorption spectrophotometer. Data were analyzed using analyticaland descriptive statistical methods. Mean age of women were 58. 85 years old. Mean of energy andprotein intake from diet was 1876 kcal, 53. 3 g/day, respectively. The meanintake of magnesium from diet was 120 mg/day that was significantly lowerthan recommended dietary allowance (P<0. 05) (37%RDA). Mean ofmagnesium serum concentration in this patients was 0. 7±0. 01 mmol/L thatwas in less normal ranges. The correlation between magnesium intake andage was significantly negative. Base on this study finding, magnesium status in women withpostmenopausal osteoporosis was not siutable considering the significantcorrelation between magnesium intake and bone mineral density andimportant role of magnesium on bone metabolism, nutritional education tointake magnesium rich foods, is suggested for maintanence of bone density.
