Abstract: Objective To explore the relationship between serum magnesium (Mg) levels and glucose metabolism disorders in the elderly.Methods The data of health examination of 126 elderly people were collected in our hospital.There were 50 patients with type 2 diabetes,35 patients with impaired glucose regulation (IGR) and 41 people with normal glucose.The clinical data of the three groups were compared and analyzed.Results (1)There were no significant differences in age,body mass index (BMI) and blood lipid level among the three groups.The mean serum Mg level was lower in normal glucose group [(0.84±0.1) mmol/L] than in diabetic group [(0.75±0.11) mmol/L,P＜0.01] and IGR group [(0.78±0.12) mmol/L,P＜0.05].(2)The prevalence of hypomagnesemia was higher in diabetic group and IGR group than in normal glucose group (24%,28.6% vs.7.3%,P＜ 0.01 ).(3)The correlation study showed that the serum magnesium level was negatively associated with fasting plasma glucose and HbA1c (r= - 0.343,- 0.271,P＜0.01 ),but not associated with age and BMI.Conclusions The low serum magnesium level is associated with glucose metabolism disorders in the elderly.
