This study was conducted to identify major dietary patterns of generally healthy Korean middle-aged women and to examine associations of the dietary patterns with socio-demographic, psychological, and physical characteristics. Data were drawn from the 2001 Korean National Health and Nutrition Examination Survey (KNHANES), which is an ongoing national surveillance system. Healthy female subjects aged 40-64 years and provided the health interview examination and food frequency questionnaire (FFQ) data were included. We conducted factor analysis based on daily mean intake frequency of 26 food groups and identified 3 major dietary patterns, healthy, convenient, and alcohol-animal. The healthy pattern was characterized by higher intakes of fish, seafood, poultry, mushroom, seaweed, vegetable, tomato, potato, and fruit, the convenient pattern by processed meat and fish, ramen, noodle and rice cake, sweet snack, egg, bread, and fast food, and the alcohol-animal pattern by alcohol, poultry, meat, and fish. The healthy pattern was significantly related with higher socio-economic status, more stable family structure, healthier mentality, and sounder status of anthropometric and biochemical variables. Those with higher factor scores for the convenience pattern were found to be younger and having higher socio-economic status, higher subjective levels of health, and lower subjective levels of worry on health. Several physical characteristics significantly improved as the levels of the convenience pattern increased. The alcohol-animal pattern was significantly associated with several socio-demographic characteristics including a low education level, a young age, a small family size, and blue-collar jobs. Public health policy makers can utilize the study findings to select prior target populations with higher needs and to tailor dietary behavioral messages to lower chronic disease risks among Korean middle-aged women.

Antibiotic exposure during pregnancy have an adversely effects on offspring behavior and development. However, its mechanism is still poorly understood. To uncover this, we added ceftriaxone sodium to the drinking water of rats during pregnancy and conducted three-chamber sociability test, open-field test, and Morris water maze test in 3- and 6-week-old offspring. The antibiotic group offspring showed lower sociability and spatial learning and memory than control. To determine the role of the gut microbiota and their metabolites in the changes in offspring behavior, fecal samples of 6-week-old offspring rats were sequenced. The composition of dominant gut microbial taxa differed between the control and antibiotic groups. KEGG pathway analysis showed that S24-7 exerted its effects through the metabolic pathways including mineral absorption, protein digestion and absorption, Valine, leucine, and isoleucine biosynthesis. Correlation analysis showed that S24-7 abundance was negatively correlated with the level of VEGF, and metabolites associated with S24-7-including 3-aminobutanoic acid, dacarbazine, L-leucine, 3-ketosphinganine, 1-methylnicotinamide, and N-acetyl-L-glutamate-were also significantly correlated with VEGF levels. The findings suggest that antibiotic exposure during pregnancy, specifically ceftriaxone sodium, will adversely affects the behavior of offspring rats due to the imbalance of gut microbiota, especially S24-7, via VEGF and various metabolic pathways.

Objectives: The purposes of this study were to comprehend the subjective dental health status and the level of dental health knowledge in some middle school students and to analyze the correlation with dental health behaviors. Methods: A survey was conducted in some middle school students and the final 637 survey data were analysed. As the statistical analysis methods, the subjective dental health status, dental health knowledge and dental health behaviors according to the general characteristics were analyzed by independent t-test, one way ANOVA and Scheffe. The correlations among the subjective dental health status, dental health knowledge and dental health behavior were found by Pearson's correlation and multiple regression analysis. Results: Through correlation analysis of the subjective dental health status, dental health knowledge and dental health behavior, all showed a significant correlation. As a result of the factor analysis affecting dental behaviors, subjective dental health status was the highest (${\beta}=0.304$, p<0.001). Conclusions: The results of this study suggest that the improvement of subjective dental health status and dental health knowledge related to dental behaviors health in the middle school students should be considered. In addition, dental health education should focus on improving subjective dental health status through motivation rather than knowledge transfer training. Moreover, development programs appropriate for the middle school students whose behavioral changes are hard to obtain are needed.

Purpose: With economic development and prolonged longevity, the level of health and health disparities have became growing concerns for individual and society as well. Since youth's health status are influenced by households' socioeconomic status and associated with heath status in later stage of life, assessing health inequality in the youth is a significant step toward lessening health disparity and promoting health. We measured health inequality in high school students and decomposed it into health factors. Methods: The subjects included 3,787 high school students of 12th graders from the Korea Education and Employment Panel (KEEP) in 2004. True health status was assumed as a latent variable and estimated by ordered logistic regression model. The predicted health was used as a measure of individual health after rPSraling to [0,1] interval. Total health inequality was then measured by Gini coefficient and was decomposed into health factors. Results: Health inequality in high school students was observed. Of total health inequality, 44% was explained by biological factors such as body mass index (BMI) (32.5%) and gender (13.5%). Behavioral factors such as smoking, drinking, physical activity, hours in bed and hours of computer ussge added to 11.7%. Household income and work experiences explained 5.6% and 8.8%, respectively. School satisfaction explained 14.6%. Other school related factors such as self-assessed achievement and experience of being bullied accounted for 15.5%. Conclusion: Among the health factors, biological factor was the most important contributor in health disparity. Other factors such as health behaviors, socioeconomic factors, school satisfaction and school related factors exhibited somewhat similar magnitude. For policy purposes, it is recommended to look into modifiable factors depending BM, gender and school surroundings.

Objectives : The aim of this study was to investigate whether verbal and spatial working memory functions were impaired not only in patients with schizophrenia but also in people at ultra-high risk for first-episode psychosis. Methods : Twenty-five patients (M 13, F 12) with schizophrenia (SPR), 21 people at ultra-high risk for psychosis (UHR)(M 10, F 11) and 19 normal controls (NC)(M 10, F 9) were recruited. The working memory was assessed by using the verbal and spatial n-back test. The working memory load increased incrementally from the 0-back to the 3-back condition. Results : SPR performed significantly lower than NC and UHR in terms of hit rates of verbal and spatial n-back test. UHR subjects conducted significantly lower than NC and higher in trend-level than SPR in terms of hit rates of verbal and spatial n-back test. These differences were derived from the high working memory load (2-back and 3-back), not from the low working memory load (0-back and 1-back). There was no significant difference between the verbal and spatial n-back test across the three groups. Conclusion : These findings suggest that verbal and spatial working memory dysfunction may be general rather than differential in terms of stimuli modality, and this working memory deficit may be an important trait factor in schizophrenia.

Purpose. A natural disaster negatively affects children's emotional and behavioral adjustment. The purpose of this paper was to examine the prevalence, symptoms, and correlates of PTSD after the occurrence of Typhoon Rusa. Method. 261 elementary school children living in Kimcheon, which was a devastated rural area in South Korea by Typhoon Rusa, were selected. Data were collected 4 months after the disaster using the PTSD Reaction Index categories recommended by Frederick, severity of PTSD. Results. 12.3% of the children had either moderate or severe PTSD symptoms; 22.7% reported mild symptoms; and the remaining 65% had sub-clinical symptoms of PTSD. The most frequent symptom was recurrenct fear(67.0%). 13% to 17.2% of children exhibited difficulty in concentration, sleep disturbance, and guilt feeling. The regression model of severity of PTSD was composed of the level of exposure to traumatic experiences, grade in school, gender, negative coping style, and social support, and explained 34.3% for PTSD symptoms. Exposure to traumatic experiences was the strongest factor of all predictors. Conclusion. Emotional support from friends and coping style were correlated with PTSD severity. School-based interventions that emphasizes coping with disaster related problems and problem-solving may prove to be useful, and may aid in building close and supportive ties with teachers, classmates, and friends.

Purpose: Adolescence is viewed as a critical period in the formation of health behavior and many health behaviors developed during this era persist into adulthood. Social-cognitive theory, self-efficacy as a central construct, has been used to predict and intervene the health behavioral patterns in adolescent. Previous research demonstrated that the attachment in childhood and self-esteem as psychosocial factors are predictors of the health efficacy in adolescent and it is viewed as solely an antecedent for the lifelong health behavior. Method: To investigate the path pattern of attachment in childhood, self-esteem and health efficacy in adolescents, 381 adolescents in high school from two urban cities in Korea were recruited for cross-sectional sample. Attachment in childhood was measured using Mother-Father-Peer Scale. Self esteem was measured with Hare self esteem. Perceived self efficacy in Health was measured by the School Health Efficacy Questionnaire. The path analysis revealed a significant relationship between attachment in childhood and self-esteem, self-esteem and health efficacy in adolescents. Self esteem was the strongest contributing factor for health efficacy in adolescent. The results suggest that attachment in childhood may aid in formulating positive self -esteem in adolescents and self-esteem played a major role in predicting health efficacy in adolescents. Conclusion: Therefore, self-esteem enrichment should be incorporated with adolescent health promotion and certainly should be a component in any health education program in school health program and interventions. These results have implications of psychosocial and family related factors on health promotion and health education for the health care provider with regard to primary and secondary prevention in adolescent population.

This study was conducted to provide basic data for the prevention and management of precocious puberty by investigating the relevance of physical parents characteristics and behavioral characteristics of girls with precocious puberty. The research period was June 1, 2016 to February 25, 2017. The subjects were 312 girls matched depending on gender and age which were composed of 104 female patients of precocious puberty visiting H oriental medicine clinic and S one in Seoul, 104 girls of A control group and 104 girls of B control group attending elementary school in gun. A total of 312 of each group were compared though t-test, $X^2$-test, and ANOVA to examine the physical parent characteristics and behavioral characteristics between girls with precocious puberty and normal girls, after which influence factors for precocious puberty were analyzed through multinomial logistic regression. The main influencing factor was found to be the height of their own and mothers' menarcheal age in terms of body and parent characteristics. Other factors influencing behavioral characteristics included the frequency of meat intake and eating-out in terms of eating habits. Additionally, watching TV, hours of using smart phone and number of private institute girls attending were also found to be influencing factors. Thus, interest in school and society in increasing precocious puberty in girls is important and extensive investigation of the causes and frequency of precocious puberty is necessary.

The present study was designed to examine the impact of socioeconomic, health-related, and health behavioral factors on the health-related quality of life (HRQoL) of the Korean elderly by gender. The subjects comprised 688 men and 898 women aged 65 or more who had participated in the Sixth Korea National Health and Nutrition Examination Survey conducted in 2014. The associations of factors with the HRQoL as measured with the European Quality of Life 5 Dimensions (EQ-5D) Index were examined in a general linear model. The most influential factor on the HRQoL was depression in both men and women. The perceived health status and walking activity were also associated with the HRQoL in both men and women. The living arrangement and educational status were associated with the HRQoL in women, while the body mass index was associated with the HRQOL in men. Depression management and the promotion of walking activity are essential to the HRQoL of the Korean elderly. Particular attention must be paid to the HRQoL of older women who live alone and have a lower level of education.

The conveyance of health information through mass media is becoming more popular, even through recreation at television programs. This study aims to investigate the influence of health related TV programs for recreation on a practice action of health behavior. In particular, the relationship between attitude, belief, and behavioral practice of the TV audience is explored. Data was collected from 200 respondents for two weeks in May, 2002. The results showed that the motive of the TV audience for watching TV recreation programs was either entertainment or fun. They satisfied with the programs in general. However, the rate of desirable health behavior practice after watching those programs was low. The degree of practice was significantly correlated with belief, satisfaction, and application possibility of the TV audience to the program. In addition, two personal factors such as gender and subjective evaluation of personal health status were significant in influencing health behavior. The appearance of experts on programs was the most important factor influencing the belief of an audience. This implies that audiences want to have the health information fulfilling scientific evidences. It is suggested that TV recreation programs would be beneficial to most audience members for in receiving important health information, only if recreation and interest factors in the program as well as the evidence-based health information and knowledge are successfully combined.
