Background: Pediatric hypertension is the main cause of morbidity and mortality in pediatric populations. Purpose: To examine pediatric hypertension in a clinical setting, we used the percentile rank approach and defined hypertension as that above the 95th percentile. Methods: The present study was linked to the a national analytical cross-sectional community-based Iranian Children and Adolescents' Psychiatric Disorders (IRCAP) survey. The survey was nationwide and funded by the National Institute of Medical Research Development. The IRCAP survey included 31,000 children and adolescents aged 6-18 years in all 31 Iran provinces. The current study included 1,035 children and adolescents and linked the data of the risk factors of cardiovascular disease only in Yazd province via random cluster sampling. Results: Of the total participants, 456 (44.1%) were male and 579 (55.9%) were female. The mean age was 11.2±3.8 years (11.7±3.7 years for males, 11.0±3.6 years for females), while mean height was 146±20.0 cm overall, 147.2±22.0 cm for males, and 144.6±17.0 cm for females (P=0.009). The blood pressure distributions and percentiles were evaluated. Conclusion: Here we determined age- and height-specific 50th, 90th, 95th, and 99th percentiles of systolic and diastolic blood pressures in Yazd boys and girls using 10-cm height intervals.

Objectives: This study aimed to examine the factors that affect the school-based oral health education in adolescents. Methods: This study was analyzed using data from the Korea youth risk behavior web-based survey in 2017. A total of 62,276 adolescents participated. The collected data was analyzed using the chi-square test, and logistic regression using SPSS, version 21.0. Results: Among the general factors related to oral health education in schools, male students experienced 1.14 times more oral health education in schools compared to female students, and middle school students experienced 1.81 times more oral health education than other students (p<0.001). With respect to oral health status, the groups without tooth fractures, pain during mastication, or gum pain and bleeding experienced 1.18 times, 0.95 times, and 1.03 times more oral health education in schools, respectively, compared to the group with complaints (p<0.001)(p<0.05). With respect to oral heath behavior, the group that brushed after lunch 'sometimes' during the last seven days received 1.43 times more oral health education compared to the group that 'always'brushed after lunch. Conclusions: It is necessary to supplement, extend, and strengthen oral health education programs in schools as well as motivate and recognize such programs.

Purpose: This study was conducted to measure the levels of Health status, perceived stress, self-esteem, and achievement motivation and assertive behavior of adolescents. The relationships among these variables as well as predictors of health status were examined. Method: The sample was composed of 496 students (male: 195. female: 301) from 3 high schools in Seoul and Kyunggi-Do regions. The instruments used in this study were as follows: health status scale developed by Noh (1991), perceived stress scale developed by Park(1996), self-esteem scale developed by Rosenberg (1965), achievement motivation scale developed by Park(1986) and assertive behavior scale developed by Kim(1982). The reliability of the five instruments were examined using Chronbachs' a that ranged from, .63 to .90 in this study. The data were analyzed with the SAS program using descriptive statistics, t-test, ANOVA, Duncan multiple comparison, Pearson correlation coefficients, and stepwise multiple regression. Results: The results were as follows: 1. The mean score .of health status was 3.1, which was higher than the median of the instrument. 2. There were significant correlations of health status with self-esteem (r=.381. p=.0001), assertive behavior (r=.503. p=.0001), and perceived stress (r=-.352. p=.0001). 3. Stepwise multiple regression analysis showed that 34% of health status was affected by the level of assertive behavior (25%), self-esteem (7%), and perceived stress (2%). Conclusion: Based on these findings, assertive behavior and self-esteem appear to be specific important areas of future research as to better understand the health status of adolescents, and to develop health status-related interventions for them.

Background: Smartphones are a modern necessity. While they are convenient to use, smartphones also have side effects such as addiction. This study assessed the relationship between smartphone use, a part of everyday life in modern society, and oral health. Methods: An analysis was conducted using 2017 Korea Youth Risk Behavior Web-based Survey data. The propensity score estimation algorithm used logistic regression and 1:1 matching algorithm using nearest-neighbor matching. After matching, a total of 15,032 participants were classified into two groups containing 7,516 teenagers each who did and did not use smartphones, respectively. Results: Comparison of oral health behaviors according to smartphone use revealed a statistically significant difference in the frequency of tooth brushing per day, use of oral hygiene products, intake of foods harmful to oral health, and experience of oral health education (p<0.05). The factors affecting oral pain experience of adolescents were examined. Compared to male participants, female participants had an odds ratio of 1.627 for oral pain (p<0.05). According to the household income level, compared to the group with higher income, the group with lower income showed higher oral pain experience (p<0.05). Oral pain experience was 1.601 times more frequent among teenagers using smartphones (p<0.05). Conclusion: The results of this study indicated that use of smartphones by adolescents affected their oral health. These findings indicate the need for improved oral health management through the use of effective school oral health programs and individual counseling by oral health professionals, promotion of information dissemination through public media, and development of prevention strategies.

Purpose: This study was conducted to analyze the features of poisoning in individuals aged 0-18 years to understand the characteristics of potential victims and eventually prevent poisoning. Methods: We retrospectively analyzed poisoned children and adolescents (0-18 years) who visited the emergency department of one tertiary hospital from January 2003 through December 2013. We collected data including their age, sex, reason for poisoning, components and dose of poison, results of treatment, and psychiatric diagnosis. Results: During the study period, there were 436 cases of poisoning (male 47.2% (n=206); female 52.8% (n=230)). Subjects were classified into four groups (0-1 years, 2-5 years, 6-12 years, 13-18 years). The most common cause of poisoning in all age groups was accidental poisoning (72.9%), but intentional poisoning increased as age increased (p<0.001). Moreover, females were more often subject to intentional poisoning than males (p<0.001). The most common poisoning material was drugs (41.7%). Among intentional poisoning patients, 62.7% patients had consulted a psychiatrist, and their most common diagnosis was adjustment disorder (44.6%). Conclusion: The most common cause of poisoning in individuals aged 0-18 years was accidental poisoning, while intentional poisoning was most common among adolescents. Guardians should take care to prevent accidental poisoning, while psychiatric consultation and national moderation will be needed to prevent intentional poisoning.

Purpose: The study aimed to examine the effects of sleep pattern, stress, and attitude towards menstruation, and behavior that causes a reduction in exposure to endocrine disrupting chemicals (EDCs) in the course of premenstrual syndrome (PMS) in female adolescents. Method: In total, 200 girls attending middle school in K city were recruited via convenience sampling between December 11 and 31, 2018, and 192 subjects were selected for the analysis. Data were analyzed using descriptive statistics, an independent t-test, ANOVA, Pearson's correlation coefficient, and multiple regression. Results: Overall, 9 (4.7%), 152 (79.2%), and 31 (16.1%) students had morning-, intermediate-, and evening-type sleep pattern, respectively. The mean scores for school-related stress were highest. Scores for stress regarding relationships with friends were the lowest. The mean score for attitudes toward menstruation was 72.33 out of 147. The mean score for behavior that led to a reduction in EDCs exposure was 56.57 out of 85. The mean scores for PMS severity were 25.30 and 38.39 out of 60. Analysis of factors affecting PMS revealed that severity of menstrual pain (β=.28), use of analgesics during menstruation (β=.17), family history of PMS (β=-.16), stress (β=.19), and behavior that reduces EDCs exposure (β=-.17) exerted significant effects on PMS. The explanatory power of these variables was 37%. Conclusion: The findings propose the necessity of a health intervention program including educational information, which can reduce PMS in adolescents, induce the behaviors which can decrease exposure to EDCs, and activities for managing the stress levels.

The Korea Convergence Society. The purpose of this study was to examine the effect of suicidal attitude, perception of life, and depression on adolescents' suicide(ideation, plans, attempts). Data on general characteristics, the Attitude Toward Suicide, the Perception about Life, and the Korean version of Center for Epidemiologic Studies Depression Scale-Revised were collected in 889 second-year middle school students in the I area. Two hundreds forty six students (27.67%) indicated they had suicide ideation, 85 had suicide plans (9.56%), and 46 had suicide attempts (5.17%). The proportion of female students was significantly higher than that of male students. The suicide indices (ideation, plans, attempts) increased as one shows lower body image satisfaction, higher depression, lower subjective mental and physical health, and lower leisure satisfaction. Predictors of suicide ideation included suicidal attitude (solution and permissiveness), depression, subjective mental health, and body image satisfaction. Predictors of the suicide plan were permissiveness and solution among suicidal attitude, and depression, subjective mental health, and those of suicide attempts were permissiveness and depression. Conclusion: This study suggests that much effort is required to decrease depression and improve perception of life and suicidal attitude in the suicide prevention education for adolescents.

Purpose: Investigating the prevalence of hyperuricemia and its association with metabolic syndrome (MetS) and cardiometabolic risk factors (CMRFs) in Korean children and adolescents. Methods: This cross-sectional survey used data from the 7th Korea National Health and Nutrition Examination Survey (2016-2017); 1,256 males and females aged 10-18 years were included. Hyperuricemia was defined as serum uric acid levels were >6.6 mg/dL at 10-11 years of age (both sexes), >7.7 mg/dL for males at 12-18 years of age and >5.7 mg/dL for females at 12-18 years of age. MetS was defined by the International Diabetes Federation criteria. Logistic regression analysis was used to analyze hyperuricemia-associated risk factors. Results: The prevalence of hyperuricemia was 9.4% (male, 8.4%; female, 10.5%) (P<0.281). After adjusting for sociodemographic factors and health behaviors in multivariate analysis (model 1), the odds ratio (OR) for hyperuricemia of MetS was 3.05 (95% confidence interval [CI], 1.17-7.92; P=0.022). After adjusting for the same variables in model 1 plus obesity and all MetS components (model 2), only abdominal obesity was significant, and the OR for hyperuricemia was 3.38 (95% CI, 1.72-6.63; P<0.001) After adjusting for the same variables in model 1 plus body mass index (BMI) z scores and all MetS components except abdominal obesity (model 3), only BMI z scores was significant, and the OR for hyperuricemia was 1.59 (95% CI, 1.34-1.89; P<0.001). Conclusion: MetS, abdominal obesity, and BMI z scores were CMRFs significantly associated with hyperuricemia in Korean children and adolescents. Therefore, attention should be paid to hyperuricemia in patients with obesity or MetS.

This study sought to analyze the need for nutritional education to enhance the selection of desirable foods by adolescents. A total of 480 high school students in Incheon were surveyed and their responses were analyzed for the recognition of nutrition labeling and their consumption of processed foods and snacks. Almost all the students (93.1%) recognized nutrition labeling, but 54.6% rarely checked the nutrition labeling. The nutrients recognized as important in the nutrition label of processed foods were total fat/saturated fat/trans fat (3.75 out of 5), calories (3.68), and sodium (3.67) in that order. The recognition of the importance of calories was significantly higher in female students compared to male students (3.78 vs. 3.58, P<0.05). The information identified as important were the date of manufacture and expiration (4.21 out of 5), price (4.14), and the nutrition label (3.15). The preference for processed foods was highest in the order of beverages (4.03 out of 5), noodles (4.02), and frozen desserts (3.97), and the preference of females for processed foods was significantly higher than males (P<0.001). The time when snacks were most frequently consumed were before going to the academy (21.0%), after school (19.4%), and after attending private institutes (15.0%). The main reasons for using processed foods as snacks were taste (44.4%), 'no time to eat a meal' (26.4%), and low price (17.7%). In conclusion, while students mostly recognized nutrition labeling, the actual usage rate was low, and snacks were selected and consumed instead of meals for reasons such as attending academic institutes after school. Thus, to encourage the choice of proper processed foods and snacks for adolescents, practical nutrition education using nutrition labeling is needed.

This study aims to identify the relationship between outcome expectancy and illegal use of music sources, and examined the parallel double mediating model of reward sensitivity and social dilution of responsibility on that relationship. To achieve the purpose this study, data were collected from 302 male and female high school students living in Seoul metropolitan area, and a double mediating effect was analysed with PROCESS Macro 3.5 Model 4. Results indicated that outcome expectancy was positively correlated with reward sensitivity, social dilution of responsibility, and illegal use of music sources of high school students, whereas reward sensitivity and social dilution of responsibility were positively correlated with illegal use of music sources. This study found that reward sensitivity and social dilution of responsibility were mediating outcome expectancy and illegal use of music sources in parallel. These findings suggest that psychological mechanisms lead adolescents use illegal music sources might be important, and provide useful information for making strategies to prevent adolescents' uses of illegal music sources.
