Objectives : A few culture-confirmed cases of S. sonnei have been notified from Korean hospitals. The source of epidemic can't be firmly determined in such cases because of the rarity of this illness in the local communities and the timing of the outbreaks. The objective of this study is to estimate the source of epidemic by investigating the patients' lifestyles. Methods : Alibi verification was used to access the presumed source of the epidemic. PCR (Polymerase Chain Reaction) was used to rapidly detect the genes of Shigella in water specimens. Results : The common lifestyle trait among the Shigella infected patients was connected with Mt. Martyr in J city, Korea. The first patient's son had gone on a pilgrimage to Mt. Martyr with 41 friends and he had only eaten rice cakes on April 5th; the second patients had visited Mt. Martyr with their mother for a picnic on April 12th; the third patient had visited Mt. Martyr with 22 friends for a pilgrimage and the patient had only drunk holy water on April 13th. Therefore, the holy water of Mt. Martyr was reckoned to be the source of the epidemic. PCR detected the genes of Shigella two days before the S. sonnei was confirmed. Conclusion : The patients' lifestyles for 7 days before the onset of symptoms should be determined in terms of time, place and contacted people to find the source of infection when cases with food poisoning are seen in the hospital setting.

The aim of this study was to determine the predictors of desirable pregnancy outcomes. The subjects were 795 pregnant women participating in the 2007 Mom and Baby Expo. They were grouped by gestational age: group I (3-12 wk: n = 95), group II (13-25 wks: n = 263) and group III (26-42 wks: n = 437). We collected data for general characteristics, sociocultural factors, life styles and nutrient intakes. We also collected pregnancy outcome data of 634 pregnant women including birth weight, maternal weight gain and gestational age. Dietary intakes of the subjects were estimated by Food Frequency Questionnaire. folate, iron and calcium intakes from foods of pregnant women were 88%, 79% and 58% of KDRIs, respectively. Bivariate analysis showed that birth weight was significantly associated with pre-pregnancy BMI, maternal weight gain, maternal age, gestational age and intakes of iron, potassium, $vitaminB_1$, $B_6$, fatty acids, MUFA. And also, bivariate analysis showed that maternal weight gain was significantly associated with pre-pregnancy BMI, maternal age, gestational age and intakes of energy, potassium. Further multivariate analyses suggest that vitaminB6 may be a significant predictor for low birth weight and energy intake and maternal age for maternal weight gain. Our findings suggest that dietary and lifestyle interventions during pregnancy can improve maternal and infant pregnancy outcomes. Prepregnancy weight control and intakes of energy and vitamin $B_6$ need to be taken into considerations in developing strategic prenatal care programs to promote desirable pregnancy outcome.

Objectives : The present study was carried out to provide basic information necessary for the prevention and efficient treatment of stroke through a comparison between thr patients of the first attack and those of recurrence. Methods : The observation f3r the current study was made on 210 cases of stroke that were confirmed through brain CT-scan. The patients were hospitalized at one of two oriental medical hospitals in Seoul during 2006. Result : The main results were as follows. First, the male-to-female ratio of stroke patients were 1:1.26, with more primary stroke far females and more recurrent stroke for males. Second, in the age distribution, seventies was the top, and sixties, fifties, and forties were next in the order of frequency. A large city was the most frequent residential site and unemployment was the most frequent occupation to have stroke. The incidence of stroke became higher as patients had a taste for spicy and salty food. Third, the most common preceding disease was hypertension. In the relationship of diastolic blood pressure with recurrence, there was significance in the test of independence. Fourth, the most important precipitating conditions at the onset of stroke were rest and steeping. The most common precedent symptoms were verbal disturbance, numbness, and dizziness. In the stroke patients with hemiparesis, male and female patients usually showed It. hemiparesis. Fifth, as a result of brain CT-scan, cerebral hemorrhage was inclined to reduce but cerebral infarction was inclined to increase due to senility and change of lifestyle. Finally, total cholesterol findings disclosed that 22.4% were hypercholesteremia, 18.6 % were hyperlipemia in triglyceride findings, and 19.0% were glycosemia in glucose findings. Conclusions : The above results suggested avoidance of meat and salty fDod and positive control of hypertension and diabetes mellitus in order to prevent stroke.

This study was conducted to detennine the dietary and lifestyle factors related to bone the mineral density (BMD) of postmenopausal women with decreased BMD. The subjects (N =163) were recruited from women who visited a orthopedic clinic for BMD check up. A trained dietition interviewed subjects individually to obtain data about dietary behavior, consumption frequency of foods known as main dietary source of calcium and potassium, and clinical symptoms. The risk factors were identified by correlation and multiple regression analysis of variables. The mean age of the subjects was 66.8 yews. Most of them showed low levels of education and monthly income. The mean age of menarche and menopause were 17.2 and 48 year, respectively. The mean menopause duration was 18.7 year. Most of the consumption of calcium was centered to vegetable foods. Education level were positively correlated (r =0.272, P < 0.05) with BMD whereas age, menarch age, menopause duration, number of children were negatively correlated (r=-0.355, r=-0.240, r=-0.283, r=-0.193, respectively, p < 0.05) with BMD. The consumption of soybean, radish were positively correlated (r=0.187, r=0.158, respectively, p < 0.05) with BMD. Potassium intake with rice showed significantly negative correlation with BMD (r =-0.189, P < 0.05), but calcium intake with brown seaweeds, bean sprouts were positively correlated (r =0.247, r =0.254 respectively, p < 0.05) with BMD. Protein intake with roasted pork was also positively correlated (r =0.216, P < 0.05) with BMD. Multiple regression analysis showed that the most prominent negative predictor influencing the BMD was age. Minor negative factors influencing the BMI were age of menarche, potassium intake from rice. But the significantly positively factors influencing the BMD were consumption of radish and soybean intake, education, and protein intake with roasted pork. In conclusion brown seaweeds, radish or soybeans can be promoted as cheap foods replacing milk and milk products for menopausal women with low income.

Chungkookjang (CKJ) is a fermented soybean product and one of favorite traditional foods in Korea. In this study, the alcoholic extract from Korean fermented soybean (CKJ) and its one of major flavonoids, genistein were evaluated for their protective effect against B(a)P induced cytotoxicity and DNA damage in HepG2 cells. CKJ extract and genistein decreased B(a)P-induced cell cytotoxicity. CKJ extract inhibited DNA single strand breaks evaluated by single cell gel electrophoresis. From RT-PCR study, it was revealed that CKJ extract decrease DNA damage induced in HepG2 cells expressing CYP1A1 and 1A2 by B(a)P. The metabolizing activities of CYP1A1 and CYP1A2, as measured by the 7-alkoxy resorufin O-deethylation (AROD) assay, showed that CKJ extract and genistein inhibited CYP1A1 and CYP1A2 activities. Genistein may contribute to these biological effects of CKJ extract at least in part. All these results indicate that CKJ extract and genistein may be useful for protection against B(a)P-induced cytotoxicity and DNA damage. Therefore, the alcoholic extract of Korean fermented soybean (CKJ) is suggested to be promising functional food which can prevent the cellular genotoxicity of dietary and lifestyle related carcinogens.

Maintaining adequate fluid balance is essential for all biological functions in the body. The purpose of this study was to evaluate vulnerability to dehydration by analyzing age, gender, body mass index (BMI), and blood lipid parameters in health checkup examinees who visited Sahmyook Seoul Hospital for comprehensive health checkups. In a binary logistic regression analysis stratified by age and body mass index the odd ratio for dehydration was as high as 3.317 (95% CI: 1.666~6.605) in the 50s age group, 4.224 (95% CI: 2.038~ 8.755) in the 60s age group, and 4.610 (95% CI: 1.943~10.940) in the above 70s age group compared to 20s reference age group. Aged females showed greater vulnerability to dehydration with significance levels of P<0.01 and P<0.001. Compared to a normal weight (BMI: 18.5~22.9) the odd ratio was higher in males with an under weight (BMI: less than 18.5) (5.130 [95% CI: 1.631~16.132]) and in females with an over weight (BMI: 23.0~24.9) (1.500 [95% CI: 1.065~2.114]). In conclusion, our results showed that vulnerability to dehydration increased with age and was higher in under weight males and over weight females than that in normal weight.

Objectives : A common problem with analyzing survey data involves incomplete data with either a nonresponse or missing data. The mail questionnaire survey conducted for collecting lifestyle variables on the members of the Korean Elderly Phamacoepidemiologic Cohort(KEPEC) in 1996 contains some nonresponse or missing data. The proper statistical method was applied to evaluate the missing pattern of a specific KEPEC data, which had no missing data in the independent variable and missing data in the response variable, BMI. Methods : The number of study subjects was 8,689 elderly people. Initially, the BMI and significant variables that influenced the BMI were categorized. After fitting the log-linear model, the probabilities of the people on each category were estimated. The EM algorithm was implemented using a log-linear model to determine the missing mechanism causing the nonresponse. Results : Age, smoking status, and a preference of spicy hot food were chosen as variables that influenced the BMI. As a result of fitting the nonignorable and ignorable nonresponse log-linear model considering these variables, the difference in the deviance in these two models was 0.0034(df=1). Conclusion : There is a lot of risk if an inference regarding the variables and large samples is made without considering the pattern of missing data. On the basis of these results, the missing data occurring in the BMI is the ignorable nonresponse. Therefore, when analyzing the BMI in KEPEC data, the inference can be made about the data without considering the missing data.

Objectives: To measure the prevalence of behavioural risk factors for obesity among urban adolescent school children in Chennai, India. Methods: This study was performed as a cross-sectional study using a World Health Organization-designed Global School-based Student Health Survey questionnaire (modified for India) among adolescent school children studying in 30 randomly selected secondary and higher secondary schools in Chennai city. 1842 adolescents studying in the VIII to XII standards were randomly selected for the study. Results: In the present study, 40.7% of the students ate fruit one or more times per day and 74.5% of the students ate vegetables one or more times per day. Nearly 20% of the students ate fast food items on 4 to 7 days during the previous week. Among the students, 30.4% watched television for more than two hours per day. Nearly 68% of the girls and 22% of the boys did not participate in outdoor sports activities. When the pattern of physical activity of the students was assessed, it was observed that 15.6% were inactive, 43.4% were minimally active, and the remaining 41.0% belonged to the category of health enhancing physical activity. Among the students, 6.2% were overweight and 5.2% were obese. Conclusions: The prevalence of risk factors for obesity was quite high among the adolescents. This study also showed that a great proportion of overweight/obese adolescents had a correct perception of their body weight and they were making efforts to modify risk factors such as television viewing, computer use, a sedentary lifestyle, and unhealthy dietary habits.

Background: This study aimed to investigate associations between self-reported sleep duration and general and abdominal obesity in Korean adults stratified according to gender and age. Methods: Data from 41,805 adults, 18-110 years of age, collected by the Korea National Health and Nutrition Examination Survey (KNHANES) in 2007 and 2015, were analyzed. Multivariable logistic regression was used to calculate adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for obesity and abdominal obesity by sleep duration after controlling for sociodemographic and lifestyle variables. Results: Among individuals 30-49 years of age, there was an increased AOR for obesity only for sleep duration ${\leq}5hour/day$ compared with sleep duration 6 to 8 hour/day, both in men (OR, 1.25; 95% CI, 1.02-1.54) and women (OR, 1.56; 95% CI, 1.29-1.90), after controlling for covariates. Regarding women, there was increased AOR for abdominal obesity for sleep duration ${\leq}5hour/day$ (OR, 1.45; 95% CI, 1.18-1.78) and ${\geq}9hour/day$ (OR, 1.38; 95% CI, 1.09-1.76) compared with sleep duration 6 to 8 hour/day. However, for elderly individuals (${\geq}65years$), there was a negative association between sleep duration ${\leq}5hour/day$ and obesity, but not with abdominal obesity, in both men and women. Conclusion: This study demonstrated a significant association between sleep duration and obesity, which varied according to gender and age.
