The purpose of this study was to determine the prevalence of non-nutritive sucking in preschool children in Daejeon. This study assessed the relationship between contributing factors influencing the prevalence of non-nutritive sucking. Also, the effects of non-nutritive sucking on the primary dentition were investigated. The study included 841 children 18~65 months of age that visited a pediatric private dental clinic for oral examination. Both children and their guardians were surveyed. It was found that 32.8% of children exhibited non-nutritive sucking, and 37.7% of females displayed this behavior. The number of females showing this behavior was significantly greater than that of males. The prevalence decreased significantly with the breast-feeding period, and there was no association with either birth rank or maternal occupation. Finger sucking (62.6%) was more prevalent and of longer duration than pacifier sucking (37.4%). Malocclusion of the primary dentition was associated with the duration of this behavior.

Diabetic mellitus in an older population is associated with increased basal oxidative stress and free radical accentuated by hyperglycemic challenge. Enhanced free radical in diabetic elderly can cause the oxidative damage and such damage can be protected by antioxidant defense system. It is believed that vitamin C, A and E are the most abundant and effective antioxidants in human plasma. The purpose of this study was to determine the antioxidant status in Korean diabetic elderly using the case-control study. The antioxidant status was examined by determining plasma levels of antioxidant vitamins (vitamin C, A, E, ${\beta}$-carotene), total antioxidant status (TAS) and thiobarbituric acid reactive substance (TBARS) and intakes of vitamin C, A, ${\beta}$-carotene and retiol. Fasting glucose and HbA1c levels and serum lipid profiles (triglyceride (TG), total cholesterol, HDL-cholesterol and LDL-cholesterol) were also determined. Diabetic subjects were 122 elderly persons over 60 years old, visiting public health center, and control subjects were 96 healthy elderly persons living in Ulsan, Korea and they were matched by age, gender, smoking and drinking status. The diabetic and control subjects were divided into sub-groups according to the status of using diet therapy and vitamin supplement. The subjects were interviewed to collect data on their general characteristics, disease history, vitamin supplement, diet therapy and health-related habits by questionnaires. Their dietary intakes were obtained by means of semi-quantitative food frequency questionnaires (SQFFQ). Fasting plasma glucose and HbA1c levels were significantly higher in diabetes than in control subjects, and plasma total cholesterol level of diabetes was not significantly different from that of control subjects. However serum HDL cholesterol level of diabetes was significantly lower and serum TG level of diabetes was significantly higher than those of control group. The average vitamin A and ${\beta}$-carotene intakes of diabetes were significantly higher than those of control subjects. There was no significant difference in plasma vitamin C, ${\beta}$-carotene, and TBARS levels between two groups, but plasma vitamin A, E and TAS levels were significantly higher in diabetes than those in control group. Plasma vitamin A and TAS levels of diabetic subjects using diet therapy were higher than those of control using diet therapy, and plasma vitamin E, ${\beta}$-carotene and TAS levels of diabetic subjects using vitamin supplements were significantly higher than those of controls using vitamin supplements. These results suggested that diabetic mellitus could enhance antioxidant defences against reactive oxygen species and interest in healthy eating such as consumption of more antioxidant nutrients.

This study aimed to investigate the relationship between the nutrition quotient and the dietary intake of adolescents. A total of 393 adolescents were surveyed to evaluate their Nutrition Quotient for Korean Adolescents (NQ-A) scores and dietary intake. The average age of the survey subjects was 15 years and the average NQ-A score of the subjects was 49.11±13.35. There was no significant difference in the NQ-A scores according to gender and age. The average dietary diversity score was 3.77±0.85, and it was significantly higher in boys than in girls (p< .05) with the scores of 12-14-year-old students being significantly higher than those aged 15-18 years (p< .01). The results of comparing the percentage of recommended intake or adequate intake and the mean adequacy ratio (MAR) according to the NQ-A grade, showed that the 'High' grade had a significantly higher intake percentage of vitamin B1, B12, folate, phosphorus, iron and a significantly higher MAR (p< .05). From a long-term perspective, efforts to improve dietary habits are deemed necessary to meet an individual's nutritional requirements. Adolescents themselves should develop proper eating behaviors and acquire suitable dietary management skills to enhance their nutritional status, ultimately contributing to an improvement in their quality of life.

BACKGROUND/OBJECTIVES: Available data suggest that seasonal changes may influence the nutritional status and overall health of elderly individuals. Therefore, this study was conducted to investigate the effects of seasonal changes and related factors on energy and nutrient intake of older adults. SUBJECTS/METHODS: Individuals aged 65 years or over were prospectively enrolled in this single-center study (male: 11, female: 20). Data were collected between May 2013 and February 2014 during winter, spring, summer and autumn. Food consumption and biochemical parameters were taken during each season to assess the seasonal nutrition status of the elderly. Upon analysis of biochemical parameters (retinol, vitamin D and vitamin C), an high-performance liquid chromatography device was utilized whereas an Immulite 2000 device was utilized during analysis of serum folic acid and parathyroid hormone. RESULTS: Fruit, fat, egg and bread consumption varied seasonally in males and females (P < 0.05). During winter, daily energy intake was found to be greater than in other seasons in males (557 kcal) and females (330 kcal) (P < 0.05). Additionally, carbohydrates, vegetable protein, n-3 fatty acid and sodium intake increased in winter, while the n-6/n-3 ratio increased in summer among males (P < 0.05). Dietary fiber and sodium intake in winter, vitamin C, iron and zinc intake in spring, and cholesterol, retinol, vitamin D and niacin intake in autumn were found to be higher in females when compared to other seasons (P < 0.05). Serum parathyroid hormone level was higher in winter, and vitamin D level was higher in autumn in both genders (P < 0.05). In males, blood folic acid level was higher in winter, while vitamin C level was higher in females, and there was no seasonal variation in retinol concentration (P < 0.05). CONCLUSION: Food consumption and biochemical parameters showed significant seasonal variations in older adults. It is not clear if nutrition plans in older adults will benefit from consideration of seasonal changes in eating habits.

Objectives: Ginseng has a long history of being used in insomnia treatment and there is some evidence from animal studies of its sleep-enhancing property. From this, it can be assumed that ginseng has sleep-promoting effect in humans. The purpose of this study was to investigate the effect of Korean red ginseng on change of sleep architecture in humans. Methods: A total of 20 healthy young males with regular sleep and wake habits and without any psychiatric nor cognitive problems were selected based on review of sleep questionnaires and sleep diaries they completed followed by an interview with a board-certified psychiatrist. The subjects were randomly assigned to red ginseng or placebo for 2 weeks of trial. The total daily dose of ginseng was 4,500 mg. The polysomnographic recordings were made at baseline and at 2 weeks after. The effects of red ginseng and placebo on sleep were assessed by comparing the changes in polysomnographic variables between the two groups. Results: A total of 15 subjects, 8 from red ginseng group and 7 from placebo group, were included to undergo polysomnographic procedures. The red ginseng group showed tendencies to increase stage 3 sleep (p=0.087) and to decrease stage 2 sleep (p=0.071) from the baseline compared with the placebo group. Conclusion: Korean red ginseng tends to increase deep sleep and decrease shallow sleep. Our result is in line, at least in part, with previous findings that Korean red ginseng increased total and NREM sleep in rats. Further studies with higher ginseng dosage, larger sample size and longer trial duration should be conducted to confirm the sleep stabilizing and balancing effects of Korean red ginseng.

High blood pressure is an important determinant of the incidence of coronary heart disease, stroke, congestive heart failure, renal failure, and peripheral vascular disease. Recommendations for control of high blood pressure emphasize lifestyle modification, including weight control, reduced sodium intake, increased physical activity. Subjects who were normotensive (n=19, $47.2\pm9.0$ y, BP l16/81 mmHg) ,treatment hypertensive (n=33, $54.2\pm6.9$ y, BP 132/85 mmHg) and non-treatment hypertensive (n=14, $50.1\pm11.0$ y, 149/94 mmHg) recruited. Anthropometric assessment (height weight waist circumference, hip circumference, fat$\%$, fat mass, and lean body mass) and dietary assessments (using 3-days food records, daily nutrient intakes were inuysed by CAN PRO 2.0 were carried out. Blood and 24-hour urine were collected). Test of recognition for salt taste threshold were performed. In non-treatment hypertensive male subjects, weight, $\%$IBW, BMI, and waist circumference were significantly higher than those of normotensive and treatment hypertensive subjects (p<0.05) .Food habits were not significantly different among the three groups. Intakes of vitamin A, vitamin B,, and vitamin B, were significantly higher in normotensive group (p<0.05). Intakes of sodium and salt taste recognition threshold were the highest in normotensive group and the lowest in treatment hypertensive group (p<0.05). Blood levels of lipids and minerals were not significantly different among the three groups. Urinary calcium level of normotensive group were significantly higher than that of treatment hypertensive and non-treatment hypertensive groups (p<0.05). These results indicate that continuous management of hypertension by drug and non-drug treatment affects salt taste recognition threshold and reduced the consumption of sodium. However, dietary sodium intake exceed recommended sodium intake to prevent and treat hypertension. It is necessary to develop the lifestyle modification program that may have beneficial effects on hypertension treatment.

For the purpose of investigating the etiologic factors of early childhood caries in 18-month old infants which is an important period in pediatric dentistry, 234 infants of 18-month age and their first care-givers (mothers in most cases) who visited Ilsin Christian Hospital in Busan for the baby-care counseling and vaccination were examined. The oral examination was performed on the infants and their care-givers were individually interviewed about various items, and the data was statistically processed to yield the results as follows : 1. The prevalence rate of early childhood caries was 27.4%. 2. The percentage of the eldest child, the education level of the mother and monthly income were revealed lower in caries group infants. 3. The percentage of prolonged breast-feeding and the frequency of daily nursing was higher in early childhood caries group. 4. In early childhood caries group, the between-meal snacks were tend to be provided irregularly without predetermined time, and sugar containing snacks such as chocolates and candies were ranked in higher order whereas the fruits and milks were in lower ranks. 5. In early childhood caries group, the percentage of those performing the oral hygienic care was lower and the timing to start the toothbrushing was comparatively later. From the above results, it can be concluded that prolonged breast-feeding, poor snack habits and lower socioeconomic status act an important role in early childhood caries in 18-month old infants.

This study was carried out to investigate the exposure pathway of PBDEs in human breast milk collected from new mothers residing in Chuncheon, a comparatively clean area in Korea. The congeners of PBDE in 22 human breast milk samples were analyzed using a high resolution gas chromatography with a high resolution mass detector. The residue level of ${\sum}PBDEs$ was higher in primipara subjects than in multipara subjects (p<0.05). The levels in this study were similar to those of people in some Asian and European countries, but were lower than those of people in north America. In the congener profiles, BDE-47 (mean contribution=36.1%) was predominant, followed by BDE-153 (27%), BDE-99 (11.7%), BDE-100 (11.1%), BDE-28 (7.9%) and BDE-183 (3.5%). The sum of BDE-47 and BDE-153 accounted for more than 50% of ${\sum}PBDEs$ in most samples. BDE-47 was highly correlated with ${\sum}PBDEs$ (r=0.94, p<0.001). No strong trend was observed between PBDE levels and a number of key biological factors (women's age, weight, height and body mass index) examined in this study, however, weak correlations were observed in PBDE levels measured against dietary habits, particularly in fish consumption frequency. It seems that Korean people might be exposed to multiple sources including products of PBDEs, and particularly food resources.
