ABSTRACT
ObjectiveTo analyze the association between alcohol dependence and overweight and obesity among high school students. MethodsThis study adopted stratified cluster sampling method. Four high schools （one vocational high school included） were selected as the research sites. We used self-designed questionnaires to investigate the drinking behavior of high school students. This study used propensity score matching method to control confounding factors （e.g gender， school type， etc.）. Then we compared the differences in drinking behavior between obese/overweight group and normal weight group after matching， and used a multivariate logistic regression model to analyze the relationship between drinking behavior and overweight and obesity. ResultsA total of 811 high school students participated in the survey. 60 people were excluded due to mild and moderate weight loss， and 751 people were normal or obese/overweight. After 1：1 propensity score matching， there were 217 people each in obese/overweight group and normal group. The characteristics of gender， school type， grade and family economic level of the two groups were balanced after matching. The difference was statistically significant （P<0.05） between obese/overweight and normal group in the following： drinking of alcohol at high school， alcohol dependence， the maximum drinks at one time， drinking of alcohol at family gatherings， whether bought alcohol for others， whether their family members recommended drinking， whether they have tried to quit drinking in the past year， and the time of blush after drinking. The multivariate logistic regression analysis indicated that the degree of alcohol dependence （the alcohol use disorder score ≥ 8） was a risk factor for overweight and obesity （OR=3.600， 95%CI： 1.244‒10.424）. Besides， having bought alcohol for others and family members advising alcohol consumption were suggested to be protective factors for overweight and obesity （OR=0.525， 95%CI： 0.309‒0.890 and OR=0.377， 95%CI： 0.222‒0.641）. ConclusionHigh school students who have alcohol dependence suffer a higher risk of obesity/overweight， while high school students who may have drinking behaviors but do not have alcohol dependence have a lower risk of obesity/overweight. It is critical to guide young people on drinking in terms of health.
ABSTRACT
Lateral ankle sprain (LAS) is one of the most common sport-related injuries among basketball players. Most basketball players experience a first LAS particularly in junior high school. Thus, it is crucial to develop effective prevention strategies for LAS in junior high school populations. However, the characteristics for first-time LAS are not clear. This study aimed to compare the physical and functional characteristics of junior high school basketball players with and without a history of LAS. Two hundred and thirty-eight junior high school basketball players (128 boys and 110 girls) volunteered for this study. We asked participants to complete a self-reported injury history questionnaire. We also assessed physical functions, including range of motion, muscular strength, dynamic balance, and performance. The prevalence of LAS was 75.6% (boys: 73.4%, girls: 78.2%). Boys with a history of LAS had significantly higher height, body mass, and BMI compared to those without a history of LAS (p<0.05). Girls with a history of LAS had significantly lower scores on the star excursion balance test in the anterior reaching direction compared with the control group (p=0.015). Various measures of physical function were associated with LAS, but these associations were different between boys’ and girls’ basketball players. These findings from this study indicate that clinicians should identify sex-specific impairments associated with LAS when designing targeted intervention programs.
ABSTRACT
RESUMEN Las actividades recreativas poseen numerosos efectos positivos en el comportamiento humano, esto puede favorecer a indicadores psicológicos de relevancia como la ansiedad percibida. En tal sentido, se planteó como propósito de la investigación determinar cómo influye un programa recreativo en la disminución de los niveles de ansiedad en estudiantes de bachillerato. La investigación es descriptiva-explicativa, de orden correlacional; se diagnostican intencionalmente a 30 estudiantes de bachillerato a través del test de Beck, antes y después de implementada una propuesta recreativa por ocho semanas. Los porcentajes de ansiedad disminuyeron a medida que se implementa la propuesta de intervención, tanto de forma general como en el análisis por género, al ser significativa la disminución (p=0.003). El presente estudio evidencia que las actividades recreativas pueden contribuir a la disminución de la ansiedad en adolescentes de bachiller, tanto para el género femenino como para el masculino. Se recomienda tres acciones a futuro: ampliar el tiempo de implementación de la propuesta de intervención, realizar estudios por género y direccionar la futura investigación a un nivel cuasiexperimental.
RESUMO As atividades recreativas têm numerosos efeitos positivos no comportamento humano, o que pode favorecer indicadores psicológicos relevantes, tais como a percepção de ansiedade. Neste sentido, o objectivo da investigação era determinar como um programa recreativo influencia a redução dos níveis de ansiedade dos estudantes do ensino secundário. A investigação é descritiva-explicativa, de ordem correlacional; 30 estudantes do ensino secundário foram intencionalmente diagnosticados através do teste Beck, antes e depois da implementação de uma proposta recreativa durante oito semanas. As percentagens de ansiedade diminuíram à medida que a proposta de intervenção foi sendo implementada, tanto em geral como na análise por género, uma vez que a diminuição foi significativa (p=0,003). O presente estudo mostra que as atividades recreativas podem contribuir para a redução da ansiedade nos adolescentes do ensino secundário, tanto para raparigas como para rapazes. Três ações futuras são recomendadas: prolongar o tempo de implementação da proposta de intervenção, realizar estudos por género e orientar a investigação futura para um nível quase experimental.
ABSTRACT Recreational activities have numerous positive effects on human behavior, this can favor relevant psychological indicators such as perceived anxiety. In this sense, the purpose of the research was to determine how a recreational program influences the reduction of anxiety levels in high school students. The research is descriptive-explanatory, correlational; 30 high school students are intentionally diagnosed through the Beck test, before and after implementing a recreational proposal for eight weeks. The percentages of anxiety decreased as the intervention proposal was implemented, both in general and in the analysis by gender, as the decrease was significant (p=0.003). The present study shows that recreational activities can contribute to the reduction of anxiety in high school adolescents, both for the female gender and for the male gender. Three future actions are recommended: extend the implementation time of the intervention proposal, carry out studies by gender and direct future research at a quasi-experimental level.
ABSTRACT
ObjectiveTo investigate the alcohol drinking among high school students， determine the possible influencing factors， and provide scientific evidence for effective control of alcohol drinking among high school students. MethodsThis study adopted stratified cluster sampling and included 4 high schools in Changning District （including one vocational high school）. Self-designed questionnaires were used to investigate alcohol drinking related knowledge and behavior among high school students. The questionnaire included demographics， alcohol drinking frequency and scenarios. SPSS 20.0 was used for Chi-square test and multivariate logistic regression analysis. ResultsThere were 811 high school students included in this study. The proportion of ever alcohol drinking was determined to be 48.09% （n=390） among students. Furthermore， 36.13% （n=293） reported alcohol drinking in the past year， and 14.80% （n=120） reported drinking in the past month. The proportion of excessive alcohol drinking was 8.26% （n=67） and that of alcohol dependence was 3.58% （n=29）. Moreover， the proportion of Chinese Baijiu （Chinese liquor） drinking in the past month was significantly higher than that in the past year （P<0.05）. In contrast， the proportions of wine and rice wine drinking in the past month was significantly lower than those in the past year （P<0.05）. The logistic regression model suggested no alcohol drinking in the past 30 days， parents disagreeing to their children’s drinking， some of friends having alcohol drinking， higher frequency of attending friend gatherings， and smoking were significantly associated with alcohol drinking among the students. ConclusionAlcohol drinking is moderately prevalent among high school students. Possible influencing factors may be correlated to their parents and friends. It warrants targeted intervention measures to prevent and control the early alcohol drinking among adolescents to avert alcohol dependence.

ABSTRACT
Objectives: To describe prevalence of personality dysfuction and personality disorders (PD) and their distribution in senior high school students in Beijing. Methods: By means of cross-sectional study, 10003 senior high school students were investigated by Personality Disorder Questionnaire-fourth edition (PDQ-4), Parental Rearing Questionnaire (Egma Minnen av Bardndosnauppfor-stran, EMBU), General Information Questionnaire, and International Personality Disorder Examination (IPDE) to diagnose PD according to the criteria of ICD-10 and DSM-IV. Results: In the students of first grade, the mean score of PDQ-4 was (25. 38 ± 9. 64). Male students had higher PDQ-4 scroes than those of female. Students in rural high schools had higher PDQ-4 scroes than those of students in urban high schools. Students in general high schools had the highest PDQ-4 scroes, followed by students in disctrict-level key high schools, and the students from city-level key high schools had the lowest PDQ-4 scroes. The prevalence rate of personality dysfunction was 8. 3％ with similar distributions of PDQ-4 scroes by gender, residential area, and rank of school. In the students of third grade, the mean score of PDQ-4 was (23. 10 ± 10. 20). Male students had higher PDQ-4 scroes than those of female. The prevalence rates of personality dysfunction and PD were 5. 8％ and 1. 83％, respectively. The correlation coefficients of EMBU had statistical significances and four common factors were identified by factor analysis. The heritability of overall PD of father and mother were 0. 71 and 0. 72, respectively. The heritability of each PD cluster was higher than 0. 6. Conclusion: The prevalence rates of personality dysfunction and personality disorder in Beijing, China is lower than those in other countries. The genetic factor plays an important role in the development of PD.

Objective To explore the relationship among emotional resilience,stress and school adjustment.Methods Adolescent life events check-list,adolescent emotional resilience scale and school adjustment scale of middle school students were conducted among 394 junior high school students.Results (1)The emotional resilience score and emotion recovery score of male junior high school students(46.07±8.56,24.43±5.80) were higher than that of female ones(44.39±8.39,23.27±5.37),and the differences were statistically significant(t=1.97,2.05,P＜0.05).The total score of emotional resilience(45.46±8.50,44.83±8.56) was not statistically related with whether they were the only children(t=0.68,P=0.50).The emotional resilience score and positive emotion score of rural junior high school students(44.04±8.53,20.63±5.35)were lower than that of urban ones (46.46± 8.34,22.15 ±4.72),and the differences were statistically significant(t=-2.86,-2.99,P＜0.01).The total score of emotional resilience (47.23±7.82,44.63±8.45,43.00±8.97) in different grades was statistically significant (F=8.86,P=0.00),and the first grade students were higher than the second and third year students.(2)Psychological stress was negatively related with emotional resilience and school adjustment(r=-0.23～-0.35,P＜0.01),and emotional resilience was positively correlated with school adjustment(r=0.12 ～ 0.29,P＜0.01).The relationship between stress and school adjustment were mediated by positive emotion and emotional recovery (the mediating effect were 11.11％,21.15％).Conclusion Frotional resilience plays a mediating role between psychological stress and school adjustment.
ABSTRACT
PURPOSE: The purpose of this cross-sectional study was to investigate intake-related factors of energy drinks and educational needs regarding energy drinks in female high school students. METHODS: Subjects were 340 female high school students in Incheon, and data were collected using self-administered questionnaires. Statistical analysis was performed using the SPSS 20.0 program. RESULTS: Subjects who had drunk energy drinks were 74.3% (249 subjects) of all subjects. The first time they drank an energy drink was significantly associated with grade (p < 0.05). In 75.1% of 249 subjects who had drunk energy drinks, the places for buying energy drinks were supermarkets and convenience stores near their homes. For the effects of energy drink intake, sleeplessness (44.6%) and no effect (41.7%) were cited, and 24.5% experienced side effects such as palpitation, tremors, etc. The scores for self-diagnosis of caffeine addiction were significantly higher in the low weight group compared to the overweight group (p < 0.05). The degree of caffeine addiction was significantly associated with effects of energy drink intake (p < 0.001) and type of side effects (p < 0.001). Willingness to stop consuming energy drinks (p < 0.001) and necessity of nutrition education about energy drinks (p < 0.05) were significantly lower in the caffeine addiction group compared to the general group. About 75.0% of subjects wanted to be educated about the side effects of energy drinks and caffeine. CONCLUSION: This study shows that female high school students need proper education about the effects of intake of energy drinks. Therefore, guidelines and a nutrition education program right intake of energy drinks should be provided as well as campaigns concerning the side effects of energy drinks and caffeine in female high school students.

The purpose of this study was to examine the impact of the self-perceived stress of high school students on their oral health care and the relationship between stress and oral health care. The subjects in this study were the students in four different high schools located in Chungcheongnam-do, on whom a self-administered survey was conducted. The answer sheets from 939 respondents were analyzed by PASW Statistics ver.18.0 for Windows. The girls were more stressed than the boys about their studies, appearance and material resource, and the sophomores felt more stress about their home and studies. The group whose academic achievement was good in the past semester had the lowest stress about home and material resource, and the group whose economic standard was higher were less stressed about appearance and material resource. As a result of comparing their oral health care by general characteristics, the groups who were sophomores and whose academic achievement was good in the past semester were most excellent in that regard, and the students whose economic standard was higher and whose average weekly allowances were larger took better care of their oral health. Concerning the influential factors for oral health care, stress about peer relationship was positively related, and stress about material resource was negatively related. Given the findings of the study, the development of oral health care programs that include how to relieve stress is required, and more intensive education is necessary as well. Besides, education for school personnel in charge of student health management and the development of related manuals are both required.

ABSTRACT
The purpose of this study was to evaluate the prevalence rate of low back pain (LBP) in the high school students and to analyze the differences and correlations with the spinal-pelvic structural variations and disability index with LBP. The subjects are 499 high school students (236 males, 263 females: mean age, 16.38 years). They were assessed for LBP with the numerical rating scale (NRS) and for disability with the Korean version Oswestry disability index (KODI). All subjects were to take the plain radiographic examination for spinal-pelvic structural variations including thoracic, lumbar, thoracolumbar Cobb's angle, lumbar lordotic curve, sacral slope, pelvic tilt and pelvic incidence. All subjects were divided into two groups by NRS scores (0, 1=no/minimum pain group [NMP group], 2-10=low back pain group [LBP group]). The prevalence rate of LBP of all subjects was 56.7% (n=283). NRS and total KODI scores were higher in the LBP group (3.38 cm/11.83%) than NMP group (0.07 cm/2.74%) (p0.05). NRS had significantly positive correlation with KODI (p0.05). In conclusion, this study showed high prevalence rate of LBP in the high school students, but did not show significant correlations with the spinal-pelvic structural variations and disability index.

Las respuestas obtenidas a través de preguntas realizadas a grupos de estudiantes de enseñanza secundaria (focus group) en las ciudades más grandes de Chile, sobre en quién y en qué instituciones confía, son unánimes: sólo se confía en la familia, y respecto a las instituciones, no se confía en ellas. En la búsqueda de aquello que podría subyacer a las respuestas, encontré que la confianza opera como un sistema de inclusión/exclusión. La confianza en la familia es un nosotros incluyente que evidencia la existencia de un "ellos", afuera de los cuales hay que protegerse. Por el contrario, la desconfianza en las instituciones es un nosotros excluyente, que entrega beneficios para otros y somete a sus arbitrariedades. Excluidos del nosotros social, sólo queda ser unos "ellos" definidos por otros, sin vida propia.
The answers obtained through questions from groups of high school students (focus group) in the biggest Chilean cities, about what institutions and whom they trust in, are unanimous: they only trust in their families; and with reference to institutions, they do not trust in them. When looking for something that could underlie the answers, I found that trusting functions like an inclusion/ exclusion system. Trusting in the family is an including we which evidences the existence of a "they", when being out of them, protection is required. On the contrary, mistrusting in institutions is an excluding we, which provides others with benefits and subdues to their arbitrariness. Excluded from the social we, then we have to be some "they" defined by others, without an own life.

Na busca daquilo que poderia estar subjacente às resposta, encontrei que a confiança opera como um sistema de inclusão/exclusão. A confiança na familia é um nós inclusivo que evidencia a existencia um "eles", contra os quais é preciso proteger-se. Ao contrario, a desconfiança nas instituições é um "nós" excludente, que entrega beneficios para outros e se submete às suas arbitrariedades. Excluídos do nós social, só resta ser uns "eles" definidos por outros, sem vida própria.
