Seasonal Difference of Nutrient Intake, Serum Lipid and Antioxidative Index in Female College Students: Young Sook Ko, Hong Seok Ahn; Korean J Community Nutr 2007;12(2):142-149. Published online April 30, 2007

Abstract PDF: To evaluate the seasonal differences of nutrient intake and serum biochemical indices (total cholesterol, HDL-, LDLcholesterol, TG, MDA:malondialdehyde, TAS : total antioxidant status, folate) in Korean college women with a mean age of 20.15y, this study was conducted twice: once in winter and a second time in summer. Anthropometric assessment was also measured in the two seasons. As a result, body fat mass (p < 0.05), body fat% (p < 0.05), and abdominal fat% (p < 0.01) in the summer were significantly lower than those in winter. Intake of fat (p < 0.05), polyunsaturated fatty acid (p < 0.01), zinc (p < 0.05), and vitamin E (p < 0.05) were at significantly higher levels in the summer period compared with the winter period. In addition, nutrients with an intake level less than 75% RI of KDRIs were folate in winter and calcium, and folate in the summer. Total cholesterol (p < 0.05) and HDL-cholesterol in summer, according to lipid profiles, were significantly lower than those in winter. Although MDA, one of the products of lipid peroxidation, remained unchanged, TAS was significantly higher in summer than in winter. The level of folate in summer showed significantly lower than that in winter. The present study suggests that nutrient intake of college women women differs according to the seasons and anthropometric indices and serum biochemical indexes were associated with seasons. Thus nutritional education programs on the basis of season are needed for college women.

Obesity Indices and Plasma Total Antioxidant Status in Hypertensive Elderly Living in Ulsan Area: Jung Hee Kim, Mi Joung Kim, Ho Kyung Kwak; Korean J Community Nutr 2006;11(2):279-288. Published online April 30, 2006

Abstract PDF: The role of free radicals in the progression of many diseases and aging has been given a great attention and total antioxidant status (TAS) has shown to be reduced with aging. The incidence of hypertension has shown to be relatively high in the aged population, and it is known to be associated with increased obesity and oxidative stress. The aim of this study was to examine the obesity indices and the total antioxidant status in hypertensive elderly (64y

Comparison of Nutrient Intake and Antioxidant Status in Female College Students by Skin Types: Hyun Sook Bae, Yunhi Cho, Ju Young Kim, Hong Seok Ahn; Korean J Community Nutr 2006;11(1):63-71. Published online February 28, 2006

Abstract PDF: The objective of this study was to evaluate whether nutrient intakes and serum biochemical indices are associated with the skin condition of humans. Anthropometric data, skin surface hydration, ceramide content, dietary intake of nutrients and serum lipids (total cholesterol, HDL-, LDL-cholesterol, TG, MDA: malondialdehyde, TAS: total antioxidant status) were obtained from 36 healthy young women. Subjects were classified into 2 groups {LM: Low Moisture Group (n = 20), HM: High Moisture Group (n = 16)} by forehead skin hydration. The results of this study were as follows: The average age, BMI, total body water, LBM, body fat%, WHR, forehead hydration, ceramide content were 20.2 yrs, 20.7, 28.8 l, 39.2 kg, 28.0%, 0.8, 44.3%, and 1.05 microgram/microgram protein, repectively. The intakes of SFA (saturated fatty acid), MUFA (monounsaturated fatty acid) in the HM group were significantly higher (p < 0.05) than in the LM group, but zinc intakes in the LM group were higher than in the HM group. Serum levels of TAS in the LM group (1.27 mmol/l) were significantly higher (p < 0.05) than that of in the HM group (1.20 mmol/l). Whereas other lipid levels were not significantly different, intakes of vitamin B6 and folate showed significant positive correlation with the forehead hydration (r = 0.447, r = 0.377). Intakes of calcium and phosphorus showed significant negative correlation with forearm ceramide content (r = -0.496, r = -0.485). Several associations between nutrient intakes and skin conditions were observed, indicating that changes in baseline nutritional status may affect skin health.

Comparison of the Total Antioxidant Status and Usual Dietary Intake in Normal and Overweight Males: Soon Kyung Kim, Young Sook Park, Kwang Eui Byoun; Korean J Community Nutr 2000;5(4):633-641. Published online December 31, 2000

Abstract PDF: This study was conducted to measure the difference in the total antioxidant status(TAS) of overweight and normal weight adults, and to investigate the correlation between TAS and the nutrient intake. Anthropometric parameter, TAS, biochemical parameters and dietary intake were measured in the normal weight group(n=17, BMI 20-25, obesity index 90-110%, body fat 16-20%) and overweight group(n=13, BMI > 25, obesity index > 120%, body fat > 25%) among Korean young males. The TAS of the overweight group was significantly higher than that of the normal weight group(p<0.01). Among biochemical parameters, the average uric acid concentration of the overweight group was significantly higher(p<0.05) compared to that of the normal weight group indicating, the uric acid concentration reflects TAS. Usual dietary intake showed that the intakes of Ca and vitamin B2, are below RDA. The average intake of vitamin C in the overweight group was significantly lower than that in the normal group(p<0.05). There was no difference in the intake of carotene and vitamin E between groups. The diet quality of both groups was satisfactory. The result of the correlation analysis on TAS, the uric acid concentration, and the measured indexs are as follows : In the overweight group, TAS was negatively correlated with alchol drinking, and uric acid concentration was positively correlated with BMI, obesity index, and TAS. In conclusion, TAS was significantly higher in the overweight group than that of the normal group, although no association was found with nutrient intakes. Serum uric acid showed a positive relationship with TAS indicating, it is a possible determinant of the antioxidant capacity.
