Purpose: This review examined literature relevant to adolescent's health behavior in order to identify key behaviors and factors related to health behaviors for targeting health promotion interventions. Method: A critical review of 29 research articles was carried out using the guidelines suggested by Cooper. Result: The majority of the studies were descriptive and cross-sectional. Generally. the study includes sub-dimensions such as general hygiene and daily life habit, safety and accident prevention, nutrition and eating (tobacco, drinking), exercise, mental health and stress management, health duty (drug, health examination, disease prevention). Factors highly related to health behaviors were age, living areas, economic status, parent health behaviors, parent health concern, social support, friends influence, self-efficacy, self-esteem, locus of control, and the perceived health status. Sex, parent education and health knowledge were not related to health behaviors of adolescents. Conclusion: Several conceptual and methodological problems were identified in the studies review, such as restricted conceptualization of health behaviors and sampling issues which limit the generalizability of the study outcomes. Further research is needed to enhance the concept clarification and generalizablity of the study results.

Yoga has been known to have stimulatory or inhibitory effects on the metabolic parameters and to be uncomplicated therapy for obesity. The purpose of the present study was to test the effect of an 8-week of yoga-asana training on body composition, lipid profile, and insulin resistance (IR) in obese adolescent boys. Twenty volunteers with body mass index (BMI) greater than the 95th percentile were randomly assigned to yoga (age $14.7{\pm}0.5$ years, n=10) and control groups (age $14.6{\pm}1.0$ years, n=10). The yoga group performed exercises three times per week at 40~60% of heart-rate reserve (HRR) for 8 weeks. IR was determined with the homeostasis model assessment of insulin resistance (HOMA-IR). After yoga training, body weight, BMI, fat mass (FM), and body fat % (BF %) were significantly decreased, and fat-free mass and basal metabolic rate were significantly increased than baseline values. FM and BF % were significantly improved in the yoga group compared with the control group (p<0.05). Total cholesterol (TC) was significantly decreased in the yoga group (p<0.01). HDL-cholesterol was decreased in both groups (p<0.05). No significant changes were observed between or within groups for triglycerides, LDL-cholesterol, glucose, insulin, and HOMA-IR. Our findings show that an 8-week of yoga training improves body composition and TC levels in obese adolescent boys, suggesting that yoga training may be effective in controlling some metabolic syndrome factors in obese adolescent boys.

BACKGROUND/OBJECTIVES: Most child and adolescent food literacy measurement tools focus on nutrition and food safety. However, the importance of aspects related to the food system such as food distribution and food waste and their effects on environmental sustainability is growing. We therefore developed and validated a two-dimensional tool for children (8-12 years old) and adolescents (13-18 years old) that can comprehensively measure food literacy. The association of food literacy with diet quality and self-reported health was assessed. SUBJECTS/METHODS: First, we developed a food literacy conceptual framework that contains food system and literacy dimensions through a literature review, focus group interviews, and expert review. After a face validity study, we conducted the main survey (n = 200) to validate the questionnaire. Construct validity and reliability were assessed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and Cronbach's alpha. RESULTS: As a result of the Delphi study, content validity was confirmed for the remaining 30 items after two items were excluded (content validity ratio = 0.86). Eleven items were excluded from the EFA results, while the CFA results indicated appropriate fit indices for the proposed model (comparative fit index = 0.904, root mean square error of approximation = 0.068). The final food literacy questionnaire consisted of 19 questions and comprised 5 factors: production, distribution, selection, preparation and cooking, and intake. Food literacy was positively associated with diet quality, as assessed by the Nutrition Quotient score, in both children and adolescents and with self-reported health in adolescents.

Purpose: This study was conducted to identify the factors influencing sleep among Korea adolescents. Methods: This was a secondary data analysis of the 7th-8th National Health and Nutrition Survey 2016-2020. Participants were 1,984 people age 12-18. Data were analyzed using frequency, percentage, χ² test, and complex sample multiple logistic regression analysis. Results: The risk of sleeping more than 10 hours was 2.50 times higher in normal subjects, than subjects underweight in body weight perception (95% CI= 1.29-4.81). The risk of sleeping more than 10 hours was 2.10 times higher in overweight subjects, than subjects underweight in body weight perception (95% CI= 1.14-3.87). The risk of sleeping less than 8 hours was 1.36 times higher in subjects high in stress status, than subjects low in stress status (95% CI= 1.05-1.75). The risk of sleeping more than 10 hours was 1.99 times higher in subjects who had not eaten, than subjects who had been eating breakfast (95% CI= 1.11-3.55). Conclusion: Thus, it is necessary to intensify sleep management required through proper health behavior as well as the mental health management of adolescents and improvement in eating behavior.

This study aimed to investigate the relationship between eating speed and nutritional status among Korean high-school students using Nutrition Quotient for Korean Adolescents (NQ-A). In this study, a questionnaire survey was conducted in 453 high-school students (227 boys and 226 girls) from September 2019 to October 2019 in Chungbuk area. Based on the self-reported speed of eating data, subjects were classified into a fast group (n=180), a medium group (n=184), and a slow group (n=89). NQ-A scores for each group were measured in each speed group. In the environment section, girls showed a significant difference in usage time of electronic devices, such as TVs and smartphones: the fast group spent significantly more time than the medium group (p=0.035). In the practice section, among boys, the slow group had significantly higher scores for washing hands before eating than the medium and the fast groups (p=0.022). This study suggested that eating speed of high school students is associated with health-related environment factor and practice factor of NQ-A, such as time spent on smart devices or washing hands before eating. The study results can provide baseline data for nutrition education on health management of high school students.

The purpose of this study was to investigate snacking behavior in adolescents. We selected one middle school and one high school in 11 school districts in Seoul. The subjects were 1,813 students (904 boys and 909 girls) in 21 schools (11 middle schools and 10 high schools). Subjects reported their snacking behavior: snack frequency, snack type, snack time, with whom to eat snack, place to purchase snack. The subjects were classified into four groups by gender and schooling. The mean snack frequency was 2.8. Girls ate snacks more frequently than boys (p < 0.001). More than half of subjects ate 1 to 3 snacks a day. Only 9.3% of them did not eat any snack. Tangerine was highly ranked in snack type. Each subject groups had different snack time (p < 0.01) and type of snack (p < 0.001). Most snack was consumed alone (46.6%), however they mainly ate fruits and other foods with family. 46.9% of snacks were purchased outside. A typical snack time was 'before dinner' for most snacks except fruits. Unhealthy foods like soft drinks, cookies, chips, candies, chocolates, ice creams had relatively high proportion in snack consumption with friends. In conclusion, adolescents had different snacking behaviors by their age and gender. These results indicate necessities of multi-dimensional efforts at home, school, media and government level considering adolescents' age and gender for their healthy snacking behavior.

Thesedays, Home Economic in Korea is faced with the danger of a discord caused by the outer pressure of reorganization in the process educational reformation. The first purpose of this study was to examine the characteristics of the informatized society and the changes of families lived in the informatized society. The second was to assert to strengthen Home Economics in the informatized society. Ultimately we suggested an integrative and interdisciplinary model about Home Economics from the ecological and informative perspective. This model consist with three parts: Human development(Child studies, Gerontology, & Adolescent studies) and family studies division(Family relation studies, family resource management studies, & Consumer studies) Environmental division(Clothing and Textiles, Food and Nutrition, & Housing) and HEIS(Home Economics Information System). This classification is correspond with the one Human-Behavioral Environment and Human-Constructed Environment of Ecological theory.

BACKGROUND/OBJECTIVES: Previous research has shown maternal betaine supplementation alleviates fetal-derived hepatic steatosis. Therefore, this study examined the anti-inflammatory effect of maternal betaine intake in offspring mice and its mechanism. MATERIALS/METHODS: Female C57BL/6J mice and their offspring were randomly divided into 3 groups according to the treatment received during gestation and lactation: control diet (CD), fatty liver disease (FLD), and fatty liver disease + 1% betaine (FLD-BET). The FLD group was given a high-fat diet and streptozotocin (HFD + STZ), and the FLD-BET group was treated with HFD + STZ + 1% betaine. After weaning, the offspring mice were given a normal diet for 5 weeks and then dissected to measure the relevant indexes. RESULTS: Compared to the CD group, the offspring mice in the FLD group revealed obvious hepatic steatosis and increased serum levels of alanine aminotransferase, interleukin (IL)-6, and tumor necrosis factor (TNF)-α; maternal betaine supplementation reversed these changes. The hepatic mRNA expression levels of IL-6, IL-18, and Caspase-1 were significantly higher in the FLD group than in the CD group. Maternal betaine supplementation reduced the expression of IL-1β, IL-6, IL-18, and apoptosis-associated speck-like protein containing C-terminal caspase recruitment domain (ASC). Maternal betaine supplementation also reversed the increasing protein expressions of nitric oxide dioxygenase-like receptor family pyrin domain containing 3 (NLRP3), ASC, Caspase-1, IL-1β, and IL-18 in offspring mice exposed to HFD + STZ. Maternal betaine supplementation decreased the homocysteine (Hcy) and s-adenosine homocysteine (SAH) levels significantly in the livers. Furthermore, the hepatic Hcy concentrations showed significant inverse relationships with the mRNA expression of TNF-α, NLRP3, ASC, and IL-18. The hepatic SAH concentration was inversely associated with the IL-1β mRNA expression. CONCLUSIONS: The lipotropic and anti-inflammatory effect of maternal betaine supplementation may be associated with the inhibition of NLRP3 inflammasome in the livers of the offspring mice.

This study was conducted to investigate the relationship among body image Perception, eating behavior and health status in young females. The survey was carried out by self-questionnaires for 293 female high school students(HS) and 164 female college students(CS) living in Daegu and suburbs of Daegu. For the perception of body image, 9-grade body figure drawings were used based on average Korean body size. EAT-26 and Rosenberg Self-Esteem Scale were used to measure the tendency of eating disorder and self-esteem. It appeared that 40.5% of the subjects were off the normal range of body weight; especially 34.2% of the subject were underweight. The subjects' perception about current body image was within normal range. Almost of all the subjects believed that the ideal body image was thinner than their own current body image, and they wanted to be thinner than their current body image. The change of eating behaviors related to weight control of CS was significantly higher than that of HS students. EAT-26 score, self-esteem score, and subjective health status score were no difference between groups. The cut-off point of the eating disorder in this study was equal to or greater than 20 in EAT-26 score. The rates of the eating disorder were very high as 9.6% of HS and 8.5% of CS. Eating disorder was positively correlated with BMI, current body image, dissatisfaction of body image and the change score of eating behavior. But eating disorder was negatively correlated with health status. From the results of this study, we suggested that one of causes related to the eating disorder behaviors in adolescent females was resulted from misperception about ideal body image. There is a great need to provide nutrition educations concerning appropriate perception of body image and weight control among adolescent females.
