| Abstract | |
A cross-sectional study was carried out to evaluate Mg status in patients with type 2 diabetes mellitus. The sample comprehended 51 individuals, both male and female, aged 53.6 ± 10.5 years, selected from the Endocrinology Clinic of the University Hospital Onofre Lopes (HUOL) in Natal/RN, Brazil. The project was approved by the Commission on Ethics in Research of the HUOL and Faculty of Pharmaceutical Sciences of the University of São Paulo. The patients were assessed concerning anthropometry, diet, blood-glucose control, kidney functioning and lipid profile, besides plasma, erythrocyte, urinary and dietary Mg. An adequate intake of macronutrients and a low consumption of dietary Mg and fibers were observed. Unsatisfactory blood-glucose control and lipid profiles, besides kidney functioning without significant alterations, were also observed. Concerning Mg status, 70.6% of the sample presented biochemical parameters for this mineral below the reference values, and such parameters were lower in individuals with more extensive metabolic complications and microalbuminury. Inverse correlations between plasma Mg with fasting (r = -0.281, p = 0.046) and postprandial plasma glucose (r = -0.322, p = 0.021), and a positive correlation between urinary Mg with fasting plasma glucose (r = 0.291, p = 0.038), waist circumference (r = 0.288, p = 0.041) and body weight index (r = 0.282, p = 0.045) were observed. Therefore, alterations in Mg status were detected in the studied population. Such alterations were more evident in patients with more extensive complications, thus demonstrating the association of factors related to this disease and Mg. (AU) | |
