Relationship between Serum Levels of Microminerals and Lipids in Korean Adults on Self-Selected Diet

Choi, Mi Kyeong

Abstract

The purpose of this study was to investigate the relationship and lipids in healthy adults on self-selected diets. These subjects consisted of 40 female college students residing in Chungnam. Anthropometric measure-ments, diet intake measurements, and blood collection were conducted. Serum concentrations of 5 microminerals(As, Cr, Mn, Se, Ni), lipids(triglyceride, total cholesterol, HDL-cholesterol), and glucose were measured by an ICP spectrometer and biochemical analyzer. The results were as follows. The mean age of the subjects was 22.34 years and the mean weight, height, and BMI were 52.89kg, 161.29cm and 20.34, respectively. The mean serum concentrations appeared to be 14.60ug/dl(As), 1.87ug/dl(Cr), 0.18ug/dl(Mn), 23.50ug/dl(Se), 0.21ug/dl(Ni), 60.73mg/dl(triglyceride), 138.49mg/dl(total cholesterol), 65.95mg/dl(HDL-cholesterol), 60.39mg/dl(LDL-cholesterol) and 88.82mg/dl(glucose). When analyzed by Pearson's correlation coefficient, the serum concentration of Cr was negatively correlated with Ca and vitamin B12 intake(p<0.05, p<0.05) respectively, Mn was negatively correlated with Na intake(p<0.05), Ni, however, was positively correlated with K intake(p<0.05). The serum concentration of Se was positively correlated with LDL-cholesterol(p<0.05), Ni, however, negatively correlated with total cholesterol, HDL-cholesterol, LDL-cholesterol, and glucose, respectively(p<0.001, p<0.01, p<0.05). Further studies are needed to clarify the precise micromineral intakes, nutritional assessment of microminerals, and cause-effect relation of microminerals and serum lipids.
