Objectives: An association between dietary patterns and mental health in children has been suggested in a series of studies, yet detailed analyses of dietary patterns and their effects on ADHD (attention deficit hyperactivity disorder) are limited. Methods: We included 4569 children who had dietary intake data as part of the CHEER (Children's Health and Environmental Research) study conducted nationwide from 2005 to 2010. We assessed ADHD (Attention Deficit Hyperactivity Disorder) by the DuPaul's ADHD Rating Scales and dietary intake by a semi-quantitative food frequency questionnaire. Using intake data, we constructed five dietary patterns: "Plant foods & fish," "Sweets," "Meat & fish," "Fruits & dairy products," and "Wheat based." Results: The overall proportion of ADHD was 12.3%. Boys (17.8%) showed a higher rate of ADHD than girls (6.5%). The total intake of calories (85 kcal) and plant fat (2g) in the ADHD group was significantly higher than that of the normal group. ADHD was significantly negatively associated with dietary habits such as having breakfast and meal frequency, and positively associated with eating speed, unbalanced diet, overeating, and rice consumption. Regarding dietary patterns, the "Sweets" category was relevant to high ADHD risk (OR 1.59, 95% CI: 1.18, 2.15 for Q5 vs. Q1) in a linear relationship. An inverse, non-linear association was found between "Fruits & dairy products" and ADHD (OR 0.55, 95% CI: 0.39, 0.76 for Q4 vs. Q1). Conclusions: Our study confirms both positive and negative associations between diet and ADHD in elementary school age children. Moreover, linear or nonlinear associations between diet and ADHD draw attention to the possible threshold role of nutrients. Further studies may consider characteristics of diet in more detail to develop better intervention or management in terms of diet and health.

에너지절감에 대한 인식이 높아짐에 따라 점차 건물이 밀폐화되고 있으며, 이로 인하여 실내공기질에 영향을 미치는 건축자재로부터의 휘발성유기화합물 방출에 대한 관심이 높아지고 있다. 그러므로 실내공기질을 개선하는데 있어 건축자재로부터의 VOCs 방출특성을 파악하는 것이 무엇보다 중요하다. 본 연구에서는 우리나라가 온돌문화인 점을 고려하여 대표적인 건축자재인 온돌마루와 접착제를 대상으로, 방출챔버시험을 통하여 온도 및 시간경과에 따른 헥산, 톨루엔 및 TVOCs 방출특성을 살펴보았다. VOCs의 방출속도는 온도와 비례관계를 나타내었으며, 바닥재에 존재하는 VOCs 발생원이 어느 위치에, 어떠한 형태로 존재하느냐가 시간의 경과에 따른 방출특성에 크게 영향을 미친다는 것을 알 수 있었다. 즉, 건축자재로부터의 헥산, 톨루엔의 방출은 전반적으로 초기에 방출속도가 높고 시간이 지남에 따라 점차 줄어드는 경향을 보이고 있으나, 온돌마루로부터의 톨루엔 방출은 다른 양상을 보이는데 시간이 지남에 따라 방출속도가 오히려 증가하여 6시간 경과 후 최대값을 보인 뒤 점차 감소하는 경향을 나타내었다. 이는 온돌마루에 함유되어 있는 톨루엔 발생원이 자재의 내부에 많이 존재하고 있기 때문에 시간이 경과함에 따라 방출속도가 증가했다가 다시 감소하는 경향을 보인 것으로 추정된다. 바닥재로부터의 VOCs 방출특성 실험결과를 종합하여 살펴보면, 온돌시스템에서 방출되는 고농도의 VOCs에 인체노출을 줄이기 위해서는 이사하기 전에 적어도 72시간 이상의 Bake-out 시간이 필요할 것이라 사료된다.

Objectives : The objective of this study was to determine the relationship between past smoking and the risk factors for metabolic syndrome. Methods : From January 2007 to December 2007, a total of 3,916 over thirty years old male health screen examinees were divided into the nonsmoking, smoking, ex-smoking groups. The diagnosis of metabolic syndrome was based on the criteria of the NCEP ATP III(Executive Summary of The Third Report of The National Cholesterol Education Program). Metabolic syndrome was defined as the presence of three or more of the following: a blood pressure $\geq$ 130/85 mmHg, a fasting glucose level $\geq$ 110 mg/dL, a HDL-C (High Density Lipoprotein Cholesterol) level < 40 mg/dL, a triglyceride level $\geq$ 150 mg/dL and, a waist circumference men $\geq$ 102 cm, but a waist to hip ratio > 0.90 was used as a surrogate for the waist circumference. Results : After adjustment for age, alcohol consumption and, exercise in the smokers, for the ex-smokers compared with the nonsmokers, the odds ratio (OR) of a lower HDL cholesterol level (<40 mg/dL) was 1.29 (95% CI=1.03-1.61) in the smokers, the ORs of a higher triglyceride level were 1.35 (95% CI=1.09-1.66) in the ex-smokers and, 2.12 (95% CI=1.75-2.57) in the smokers, and the OR of a waist to hip ratio was 1.25 (95% CI=1.03-1.52) in the ex-smokers. When there were over three components of metabolic syndrome in the ex-smokers and smokers as compared with the nonsmokers, the odds ratio against the risk of metabolic syndrome were 2.39 (95% CI=1.00-6.63) and 2.37 (95% CI=1.02-6.46), respectively. Conclusions : The present study suggested that there is an association of smoking with metabolic syndrome in men.

본 연구는 계획적 행동이론을 적용하여, 소비자의 과일 섭취의도에 영향을 주는 요인을 파악하였다. 또한 건강 행동관련 연구에서 상관성이 높게 나타난 '습관' 요인을 추가하여 새로운 연구모형을 개발하여 과일섭취 의도와 과일섭취 행동에 영향을 미치는 요인을 파악하였다. 서울 지역에 거주하는 소비자 734명의 설문조사를 실시한 결과, 과일섭취에 대한 태도, 사회적 규범, 지각된 행동통제, 과일섭취 습관이 과일섭취 의도에 긍정적인 영향을 미치는 것으로 나타났다. 따라서, 과일 섭취의도를 높이기 위해서 과일 섭취에 대한 태도, 사회적 규범, 지각된 행동통제 등을 증가시킴으로써 가능하다는 것을 확인할 수 있었다. 한편 과일섭취 의도가 과일섭취 행동에 미치는 영향에 대한 과일섭취 습관의 조절효과를 분석한 결과, 과일섭취 습관이 과일섭취 의도가 과일섭취 행동으로 이어지는 과정에 (-)의 방향으로 영향을 미치는 것으로 나타났다. 다시 말해서, 과일을 습관적으로 섭취하는 경향이 강한 사람들은 그렇지 않은 사람들에 비해 섭취행동이 섭취의도의 영향을 상대적으로 덜 받는다는 것이다. 이는 개인이 행동을 수행함에 있어 습관강도가 강한 집단의 경우 의도에 의한 영향은 덜 받는 반면, 습관 요인에 의해 행동이 재현되는 경향이 크다는 것을 의미한다. 따라서, 소비자들의 과일섭취 증대를 위해 습관의 정도에 따라 대상을 구분하여 교육하거나 우선 순위 선정시 습관의 조절효과를 활용할 수 있으리라 생각된다. 과일 섭취행동조사 문항으로써 성인 기준 1일 섭취권장량과 비교한 섭취량을 포함하지 못한 것이 본 연구의 한계점이 될 수 있다. 후속연구로 하루 과일 섭취권장량 충족여부를 기준으로 권장량에 미달한 집단에 대한 심층적 분석결과는 과일섭취량을 권장량에 도달할 수 있는 방안을 제시하는데 도움을 줄 수 있을 것이다. 또한 기존의 계획적 행동이론에 '습관'이라는 새로운 요인을 추가하였던 본 연구가 과일 섭취 행동 모델에 설명력을 높였듯이 새로운 요인을 파악하는 후속연구가 필요하다.

This study was conducted to investigate the effectiveness of nutrition counseling on the dietary intake and nutritional status cancer patients undergoing radiotherapy treatment. The study was conducted over 6 week period and included 104 patients : 66 received nutrition counseling as the variable group of 42 male and 24 female and 38 patients received no counseling as the control group of 19 male and 19 female. Nutrition counseling was accompanied with the radiation therapy and adminstered via counseling session and distribution of printed material during radiation therapy for 6 weeks. Nutrition counseling aimed at maintaining a balanced diet and preventing weight loss of subjects, guideline used for energy and protein intake were 35kcal/kg IBW and 1.5-2.0g/kg IBW, respectively. Over the course of the study, the counseling group increased significantly in comparison to the control group's energy intake, evidenced by the counseling group's initial mean daily energy intake of 1932.0kcal, and 4 and 6 week mean energy intake values of 2046.6kcal, 2066kcal, respectively. But mean energy values of control group was 1614.3kcal at 4 week. Th energy intake per weight values and protein intake per weight values for initial, 4 and 6 week intervals for counseling group were 33.2kcal/kg, 33.7kcal/kg, 34.0kcal/kg, and 1.48g/kg, 1.58g/kg, 1.59g/kg, respectively. Based on results, nutrition counseling had positive effects on both the variety of diet and energy intake of the variable group, mostly due to an increase in dairy product and egg consumption. In addition, the percentage of counseling group patients who consumed all 5 food group increased from 48.5% to 54.5%. Sufficient energy intake and protein consumption seem to be important factors in weight loss prevention, evidenced by weight gain by subjects in the counseling group who had 36.1kcal/kg/day mean energy intake and 1.77g/kg/day mean protein intake after 4 weeks. Counseling group subjects experiencing weight loss had lower intake and 1.77g/kg/day mean protein intake after 3 weeks. Counseling group subjects experiencing weight loss had lower intakes of 29.3kcal/kg/day for energy and 1.33g/kg/day for protein during the same period. Another significant factor in weight loss prevention of the counseling group could be the variety of diet. The dietary variety scores(DVS) of both counseling and control groups differed significantly : the counseling group had a mean score of 34 while the control group of patients. At the end of the study, the mean percentage of subjects within each group having a DDS 5 was higher in the counseling group (54.5% v.s. 24.0%). In this study, nutrition counseling for cancer patients undergoing radiation therapy proved to be effective in preventing weight loss, a major complication during radiotherapy. Nutrition counseling not only increased protein and energy intake, but also had desirable effects on variety or diversity of diet.

Antioxidants such as vitamin C and E may play a preventive role in the development of cancer and coronary heart disease. The status of vitamins C and E may be affected by lifestyle habits such as smoking , drinking, and exercise. These habits can modify the dietary requirements of vitamin C and vitamin E. the purpose of this study was to determine whether Korean young healthy men and women consume vitamins C and E in sufficient quantities relative to their lifestyle habits. Among the participants in this study, 52% of the men and none of the women were smokers. ; 84% of all subjects drank alcohol more than once a week ; and the men exercised more often than the women. The concentrations of serum total , HDL-, and LDL- cholesterol were higher in the women than in the men, but the serum triglyceride concentrations were higher in the men than in the women. The men consumed less satuated fat than the women (p<0.05) . The daily intakes of vitamin C for the men and the women were 47.1mg and 65.6mg, respectively. On the other hand , the daily vitamin E intake was higher in the men (11.8mg) than women(6.9mg). The serum $\alpha$-tocopherol concentrations of all subjects were in a normal range, and in no subjects were they below the minimum value of ranges. However, about 19% of male subjects and 10% of female subjects showed deficient status, although the mean serum vitamin C levels were normal . Lifestyle habits fo the sort mentioned above have little influence on the serum vitamin C and $\alpha$-tocopherol concentrations. The serum $\alpha$-tocopherol concentration had a positive correlation with total fat and alcohol consumption. The serum vitamin C concentration was positively associated with regular exercise, but it was negatively correlated with the number of cigarettes smoked. Meanwhile, the serum lipid persoxide concentration , the indirect index of oxidative stress, was influenced by certain variable such as body mass index , the number of cigarettes smoked , alcohol consumption, energy expenditure, vitamin C intake, and serum ${\gamma}$-tocopherol concentration. Serum lipid peroxide concentration was positively associated with body mass index, the number of cigarette smoked , serum triglyceride , and HDL-cholesterol concentration. In conclusion , the vitamin E requirements of the subjects were met by the Recommended Daily Allowance (RDA) regardless of lifestyle habits. However, serum vitamin C concentrations showed individual variation and was below the normal ranges. Smoking and exercise influenced serum vitamin C concentration. Therefore, a reevaluation of the requirements of vitamin C relative to lifestyle habits is necessary.

The aim of this study was to investigate the relationships between eating habits and health among adolescents in Shanghai and Heze, China. A cross-sectional study was conducted in 2013 on 2,089 adolescents; 1,089 students were from Shanghai and 999 students from Heze region. Eating habits, weight, height, and nutritional knowledge were assessed using a self-administered questionnaire. Eating habits score was classified into two categories: healthy eating habits and unhealthy eating habits, based on "Korean Youth Risk Behavior Web-based Survey", for statistical data analysis. Associations between eating habits, BMI, and nutritional knowledge were examined using a general linear model with adjustment of potential confounding factors such as region, gender, age, parents' education level, and pocket money. Statistical analyses were performed using the SAS (version 9.3) program. Proportions of healthy eating habits group were 90.0% for breakfast (3-7 times/wk), 29.1% for fruit (${\geq}once/d$), 12.5% for vegetable (${\geq}3times/d$), 7.3% for milk (${\geq}2times/d$), 90.0% for fast food (<3 times/wk) consumption, respectively. The average BMI score was 20.1 (Shanghai 20.5 Heze 19.6), which is in the range of normal weight. Rates of obesity and overweight were 16.5% and 8.3% in Shanghai and Heze, respectively. There were significant negative correlations between intake frequencies of breakfast, fast food, biscuits, sugar, chocolate, and BMI score. Eating habits and nutritional knowledge score showed a significant positive correlation. These results showed better eating habits regarding eating regularity and consumption of fruits and soft drinks in Chinese adolescents compared with Korean adolescents, although cultural differences were not fully considered. This study demonstrated significant associations of BMI and nutritional knowledge with dietary behavior in Chinese adolescents in two regions of China. Further studies on Chinese adolescents from other regions in China should be considered.

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.
