The purpose of this study was to evaluate total sugars intake and determine its relationship with nutrient density and obesity degree in elementary school children. A total of 1,292 elementary school students (638 boys, 654 girls) in Chungnam participated in this study. Daily total sugars intake of subjects was analyzed using the USDA database of sugars after a questionnaire survey using 24-hour recalls. The average age of subjects was 9.7 years, daily energy intake was 1,834.0 kcal, and total sugars intake was 37.6 g/day, which was 8.3% of total energy intake. Sugars intake from the milk group was highest at 18.4 g/day, followed by fruits, cereals, sugars and sweeteners, and beverages. Nutrient density of protein as well as Na, Fe, and Zn levels were significantly lower according to total sugars intake level. There was no significant difference between overweight and obesity risk among the sugars intake quartile groups. In conclusion, total sugars intake of subjects was not significantly high and not associated with obesity risk; however, high sugars intake in children was associated with decreased consumption of protein, Fe, and Zn, which are important for growth.

Purpose: The aim of the present study was to retrospectively investigate the influence of potential risk indicators on the development of peri-implant disease. Methods: Overall, 103 patients referred for implant treatment from 2000 to 2012 were randomly enrolled. The study sample consisted of 421 conventional-length (>6 mm) non-turned titanium implants that were evaluated clinically and radiographically according to preestablished clinical and patient-related parameters by a single investigator. A non-parametric Mann-Whitney U test or Kruskal-Wallis rank test and a logistic regression model were used for the statistical analysis of the recorded data at the implant level. Results: The diagnosis of peri-implant mucositis and peri-implantitis was made for 173 (41.1%) and 19 (4.5%) implants, respectively. Age (${\geq}65$ years), patient adherence (professional hygiene recalls <2/year) and the presence of plaque were associated with higher peri-implant probing-depth values and bleeding-on-probing scores. The logistic regression analysis indicated that age (P=0.001), patient adherence (P=0.03), the absence of keratinized tissue (P=0.03), implants placed in pristine bone (P=0.04), and the presence of peri-implant soft-tissue recession (P=0.000) were strongly associated with the event of peri-implantitis. Conclusions: Within the limitations of this study, patients aged ${\geq}65$ years and non-adherent subjects were more prone to develop peri-implant disease. Therefore, early diagnosis and a systematic maintenance-care program are essential for maintaining peri-implant tissue health, especially in older patients.

The purpose of this study was to investigate the relationship among nutritional status of copper and zinc, serum leptin, and lipids of 99 middle school girls residing in kyunggi-do, Korea. Subjects were divided assigned to one of two groups such as normal (BMI<85 percentile, n=58) and obese (85$\leq$BMI, n=41) groups. Subjects were evaluated based on anthropometric measurements, 24-hr dietary recalls and blood analysis. The mean age was 13.93 years. The mean weight (p<0.001), BMI (p<0.001), body fat (p<0.001) of obese were significantly higher then those of normal group. The mean daily energy intake was 94.2% of RDA for Korean. The ratio of energy coming from carbohydrate, fat and protein was 63:24:13. The mean daily intakes of Cu and Zn were 1.4 mg and 7.4 mg (73.7% of RDA), and there were no significant difference between two groups. The mean serum levels of leptin (p<0.001), LDL-cholesterol (p<0.05), triglyceride (p<0.01), TPH (total cholesterol/HDL; p<0.001), LPH (LDL/HDL; p<0.001) and AI (atherogenic index; p<0.001) of obese were significantly higher than those of normal group. The mean serum Cu level of obese was significantly higher than normal group but, the mean serum Zn level of obese was significantly lower than normal group. Serum Cu showed a significantly positive correlations with body weight (p<0.001), BMI (p<0.001), body fat (p<0.001), serum leptin, and LPH. However, serum Zn showed a significantly negative correlations with body weight (p<0.001), BMI (p<0.001), serum leptin (p<0.001), TPH (p<0.05), and AI (Atherogenic index; p<0.05). To summarize the results, the Zn intakes of middle school girls did not reach to RDA for Koreans. Also, increase of BMI may lead to decrease of serum zinc level and increase of serum copper level, and this change of serum zinc related to the change of serum leptin and serum lipids level in middle school girls during rapid growth.

To elucidate the relationship among body mass index, nutrient intake and blood antioxidant capacity in the postmenopausal period, 60 women residing in Iksan area were recruited. Body mass index (BMI) was calculated base on height and weight, and food and nutrient intakes were estimated by 24-hour recalls of 3 non-consecutive days. Parameters of antioxidant capacity including the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and total antioxidant capacity (TA) were measured in fasting blood samples from the subjects. The average age, height, weight and BMI of the subjects were 65 years, 151.1cm, 59.5 kg and 26.0 m/kg$^2$, respectively. The macronutrient intake rate of carbohydrate : protein : fat were 65:17.5:17.5; the mean intakes of energy and protein were 1532.7 kcal (86.3% of RDA) and 67.1 g (122.0% of RDA) respectively. The mean intakes of phosphorus, vitamin A, niacin and vitamin C were higher than Recommended Daily Allowance (RDA) for Koreans. On the other hand, calcium and riboflavin intakes were only 84.6% and 70.4% of RDA. Among the parameters of antioxidant capacity, SOD activity was significantly lower in lean subjects (BMI<20) than in the normal or overweight subjects (BMI${\geq}$20) (p<0.05). TAs of the subjects with the highest intakes of vegetables and fruits were significantly higher than those of subjects with lower intakes (p<0.05). Antioxidant capacity was compared among subjects according to 3 different nutrient intake levels according percentage of RDA for Koreans for selected nutrients with the following results: The high protein and niacin groups exhibited significantly lower TA status than those of the other intake groups (p<0.05). In conclusion, the low BMI was associated with lower SOD activity in postmenopausal women. Higher consumption of fruits and vegetables was associated with higher TA. When protein and niacin intakes were excessive, SOD activity and TA tended to be low. SOD and TA, among antioxidant indexes, seemed to be mostly influenced by other factors. Therefore, more studies on the effects of nutritional intake and the activity of antioxidant enzyme should be conducted.

Picky eating behavior is a significant factor in causing unhealthy eating and disturbing the growth of children. This study examined picky eating behaviors and food intake of 112 preschoolers aged 3~5 year, picky eaters (n=41) and non-picky eaters (n=71), living in Dobong-gu, Seoul metropolitan area, South Korea. Picky eating questionnaires and three consecutive 24-hour dietary recalls were collected from their caregivers. The difference between the two groups was verified using a Chi-square test or t-test and Pearson's correlation. Compared to the non-picky eaters, fussiness, satiety responsiveness, and refusal of food variety were significantly higher in picky eaters (P<0.001). Compared to the non-picky eaters, an assessnent of the preschooler's behavior and the caregivers' perception were positively correlated in picky eaters (r=0.749, P<0.001). The intakes of shellfish (P<0.05), vegetables (P<0.001), fiber, vitamin E (P<0.01), vitamin A, and folate (P<0.05) were significantly lower in picky eaters than the non-picky eaters. The major food sources of vitamin A and folate were vegetables, of which grains were the source of fiber, fats and oils were the source of Vitamin E, and root vegetables were source of vegetables in both picky and non-picky eaters. In conclusion, picky eating behaviors are related to different fussiness and slowness in eating. Therefore, it is suggested to increase the amount of meal and vegetable intake in picky eaters.

BACKGROUND/OBJECTTIVES: The purposes of the study were to investigate folate intakes and plasma folate concentrations as well as estimate folate status in Korean healthy adults. SUBJECTS/METHODS: A total of 254 healthy 19- to 64-year-old adults (68 men and 186 women) living in Seoul metropolitan area, Gumi, and Kwangju, Korea participated. Three consecutive 24-hour dietary recalls, information on folate supplementation, and fasting blood samples were collected from the subjects. RESULTS: The mean dietary folate intakes were 587.4 and $499.2{\mu}g$ dietary folate equivalent (DFE)/day for men and women, respectively. The median dietary intakes of men and women were 566.6 and $474.6{\mu}g\;DFE/day$, respectively. Forty subjects (16.7% of total) less total folate than the estimated average requirement (EAR). Folate intakes of 23.3% of men and 34.8% of women aged 19-29 years did not meet the EAR for folate. Major food sources consumed for dietary folate were baechukimchi (Chinese cabbage kimchi), rice, spinach, eggs, and laver, which provided 44% of dietary folate intake for the subjects. Plasma folate concentrations were 23.4 nmol/L for men and 28.3 nmol/L for women, and this level was significantly lower in men than in women. Approximately 13% of men and 3% of women were folate-deficient, and the percentages of subjects showing folate concentrations lower than 10 nmol/L were 27.9% of men and 6.4% of women. CONCLUSIONS: Folate intakes of Korean adults in this study were generally adequate. However, one-third of young adults had inadequate folate intakes.

The most abundant long-chain polyunsaturated fatty acid in brain lipids is docosahexaenoic acid(C22 : 6 N-3, DHA). It is incorporated into nerve tissues mostly in utero and during the first year of life. DHA in brain is derived from either pre-formed DHA in human milk or by infant hepatic synthesis from linolenic acid in milk. This study was designed to investigate the effects of DHA supplementation on fatty acid profiles in maternal plasma lipid and breast milk. Twenty lactating women participated in the study. Seven women took 3g of fish oil per day and vitamin E for 28 days starting from the day of giving birth. Five women consumed 1.5g of fish oil as well as tivamin E, and the rest took vitamin E supplements for the same period of time. Dietary questionnaires and 3 consecutive 24-h recalls were collected to evaluate theri nutritional status and food habits. Finding that DHA intake from fish was not significantly different among three experimental groups, the partcipants were instructed to continue eating their usual home diets. Milk samples were taken on the day of giving birth, as well as the 7th, 14th and 28th day being the supplement phase, and finally 2 weeks after the cessating of DHA supplements. The amounts of the fish oil supplements produced significant dose-dependent increased in the DHA content of milk and plasma, but to a lesser degree. Base-line for 28 days raised the level to 2.05$\pm$0.43% and 1.5g/day supplement produced DHA levels of 1.02$\pm$0.19%. The results of this study indicated that relatively small amount of dietary DHA supplementation significantly elevats DHA content in milk. This would clearly elevate the infant's DHA intake which in turn may have implications for the infant's brain development.

We investigated whether socioeconomic differences affect fruit and vegetable (FV) consumption with respect to total intake and intake of various FV subgroups. Our study included 6667 adults aged 40-64 years who completed a dietary survey in the fourth Korean NHANES (2007-2009). FV intake was estimated from 24-hour recalls and food frequency questionnaires. Differences in FV consumption related to educational attainment were analyzed according to different nutritional categories of FV. Both men and women in the low-education group had the lowest intake of total FV and total fruits, and women also had the lowest intake of total vegetables. Also lowest in this group was consumption of mushrooms and vegetables (excluding kimchi) among men, and cruciferous and allium vegetables (excluding Chinese cabbage and radish) among women, while kimchi consumption was the highest in this group. Additionally, an association between educational level and intake of citrus fruits was evident among men. Adults in the low-education group consumed less carotene-rich FV, red fruit and/or vegetables, and dark-green leafy vegetables, fewer total vegetable dishes, and fewer types of fruit than in other groups. Men in this group had the lowest intake of yellow/orange fruit and/or vegetables, and women consumed the least folate-rich FV. There is a clear association between educational attainment and FV intake with regard to total intake, and to specific nutrients, bioactive compounds, colors, and variety.

Postmenopausal women lose more bone mass than men as a result of estrogen deprivation. The resultant low bone mineral density (BMD) is a major risk factor in the development of osteoporosis. Calcium, phosphorus and magnesium are main components of bone. The purpose of this study is to investigate nutrient intake and serum osteocalcin, Ca, P and Mg and their correlation to bone mineral density in Korean postmenopausal women residing in rural areas. We conducted 24 hour dietary recalls, anthropometric measurements and blood analysis on 60 postmenopausal women. The BMD of the lumbar spine (L2$\rightarrow$L4) and the femoral neck were measured by dual energy X-ray absorptiometry (DEXA). Subjects were assigned to one of three groups:normal (T-score> -1, n=20), osteopenia (-2.5> T-score $\leq$ -1, n=23), and osteoporosis ( T-score $\leq$ -2.5, n=17). The mean age, height, weight and BMI were 62.37 yr, 154.36 cm, 55.28 kg and 23.18 $kg/m^2$ respectively. The mean daily energy and protein intakes were 76.35% and 87.41% of RDA for Koreans. The mean intakes of calcium, phosphorus, and magnesium were 463.62 mg (66.23% of RDA), 955.32 mg (136.47% of RDA), 345.87 mg respectively. The mean serum levels of calcium, phosphorus and magnesium were 8.76 mg/dl, 3.80 mg/dl, and 2.10 mg/dl, respectively, and there were no significant differences among the three groups. However, the BMD of the femoral neck showed a significantly negative correlation with serum magnesium (p<0.05). To summarize the results, most nutrient intakes (especially calcium) in postmenopausal women did not reach the RDA values for Koreans. Also, increase of serum magnesium levels may be related to bone loss.
