Abriendo puertas para la vida: Programa de prevención de conductas suicidas a través de docentes Gatekeepers / Opening doors to life: A suicidal behavior prevention program involving Gatekeeper teachers / Abrindo portas para a vida: Programa de prevenção ao comportamento suicida por meio de professores Gatekeepers

Introducción: El suicidio es la tercera causa de muerte de jóvenes entre 15 y 19 años. Ante esto, los ambientes escolares pueden favorecer el fomento de la salud mental de los adolescentes, permitir la identificación temprana de factores de riesgo y aportar en la prevención de conductas suicidas. Una de las estrategias de prevención es el entrenamiento de "gatekeepers". Objetivo: Determinar el efecto del programa "Abriendo Puertas para la Vida" sobre conocimientos, actitudes y prácticas en prevención de conductas suicidas en un grupo de profesores de secundaria de una institución educativa de San Juan de Pasto, Colombia. Materiales y métodos: Estudio preexperimental, con un grupo de intervención y medidas pre y pos-seguimiento. Participaron nueve docentes voluntarios durante dos jornadas de formación. Resultados: Se identificaron cambios positivos en conocimientos, actitudes y prácticas de los participantes entre pretest y postest, en la mayoría de las subdimensiones evaluadas; sin embargo, tres años después, estos cambios se mantuvieron tan solo en conocimientos sobre las conductas suicidas y en actitudes hacia la prevención. Conclusión: El programa "Abriendo Puertas para la Vida" evidenció efectividad y pertinencia, sin embargo, el mantenimiento de sus efectos requiere de acciones de seguimiento y acompañamiento a los docentes formados.

Introduction: Suicide is the third cause of death in young people aged between 15 to 19 years. Thus, school environments can promote mental health of adolescents through early identification of risk factors and prevention of suicidal behaviors. One prevention strategy is the training of "gatekeepers". Objective: To determine the impact of the "Opening Doors to Life" program on the knowledge, attitudes, and practices regarding prevention of suicidal behavior in a set of high school teachers from an educational institution in San Juan de Pasto, Colombia. Materials and methods: A pre-experimental study with an intervention group and pre- and post-follow-up measurements. Nine volunteer teachers participated during two training sessions. Results: Positive changes regarding knowledge, attitudes, and practices of the participants during pretest and posttest were observed for the majority of evaluated sub-dimensions. However, after three years, the positive measures prevailed only for knowledge about suicidal behavior and attitudes toward prevention. Conclusion: The "Opening Doors to Life" program showed effectiveness and relevance. However, maintaining its impact requires follow-up actions and support of trained teachers.

This situation of exposure to isolation could affect the mental health of young university students. Objective: To determine the levels of depression, anxiety, and stress in university students, their relationship with sociodemographic variables, and the characteristics of social isolation during the COVID-19 Pandemic. Methods: A descriptive, observational, cross-sectional, and quantitative study was carried out with a sample of 818 university students from health sciences faculties using the DASS-21 self-administered questionnaire. Results: The main findings were a higher prevalence of high levels (severe and highly severe) in anxiety, reaching almost 4 out of 10 of those evaluated; On the other hand, in depression and stress, 2 out of 10 of those evaluated were found at the mentioned levels. Concerning the sociodemographic variables, those related to COVID-19 and social isolation, statistically significant differences were found with gender (women > men), having had COVID-19 (Yes > No), and living with relatives as before. On average, the pandemic (Yes > No) obtained higher scores in depression, anxiety, and stress. Conclusion: The students who presented greater depression, anxiety, and stress with a significant difference were female, with a history of having had Covid-19, less contact with family members, and having complied with total social isolation

Percepção e satisfação corporal de estudantes universitários vegetarianos / Perception and body satisfaction of vegetarian students / Percepción y satisfacción corporal de los estudiantes vegetarianos

INTRODUÇÃO: A percepção e satisfação corporal têm sido amplamente estudadas em diversos públicos, principalmente em estudantes universitários; porém, existem poucas investigações com vegetarianos, sendo assim, torna-se necessário avaliar se o padrão alimentar vegetariano está relacionado com os fenômenos inerentes à imagem corporal. OBJETIVO: Avaliar a percepção e a satisfação corporal entre estudantes universitários vegetarianos. MÉTODO: Trata-se de um estudo transversal com 123 participantes, no qual foram aplicados o Questionário de Imagem Corporal - BSQ (Body Shape Questionnaire) e a Escala de Silhuetas de Stunkard. RESULTADOS: Os dados mostraram que 86,2% dos participantes eram eutróficos (IMC=22,4±3,3), sendo o score obtido no BSQ foi de 84,6 pontos (±36,0) correspondente à leve insatisfação com a imagem corporal. Cerca de 82,1% dos estudantes se mostravam insatisfeitos com a silhueta, dentre estes, 61,4% desejavam diminuí-la. CONCLUSÃO: O padrão alimentar (ovolactovegetariano, lactovegetariano, vegetariano estrito e vegano) não se relacionou com a insatisfação corporal, mas sim o desejo de ter silhuetas magras que são valorizadas pelo padrão de beleza vigente.

INTRODUCTION: For Body perception and satisfaction have been widely studied among different publics, especially among college students; however, there are few investigations with vegetarians. Therefore, it is necessary to evaluate whether the vegetarian eating pattern is related to the phenomena inherent to body image. OBJECTIVE: To evaluate body perception and body satisfaction among vegetarian college students. METHOD: This is a cross-sectional study with 123 participants, in which the Body Image Questionnaire (BSQ) and the Stunkard Silhouette Scale were applied. RESULTS: The data showed that 86.2% of the participants were eutrophic (BMI=22.4±3.3), and the score obtained in the BSQ was 84.6 points (±36.0) corresponding to a mild dissatisfaction with body image. About 82.1% of the students were dissatisfied with their silhouette, and 61.4% of them wanted to reduce it. CONCLUSION: Dietary patterns (ovolactovegetarian, lactovegetarian, strict vegetarian, and vegan) were not related to body dissatisfaction, but rather the desire to have thin silhouettes that are valued by the prevailing beauty standard.

Relationship between physical activity levels and depressive symptoms in college students: a cohort study / 中国学校卫生

Objective@#To explore the association between physical activity levels and depressive symptoms among college students, so as to provide evidence for promoting physical and mental health of college students.@*Methods@#Using a cohort study design,a baseline survey of 1 415 college students in Shenyang Normal University in 2017 followed for three years from 2018 to 2020. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) and Selfrating Depression Scale (SDS) were used to evaluate the physical activity levels and depressive symptoms of college students. According to the level of physical activity at baseline (MET ·h/week), participants were divided into three groups [T1 (≤36.4), T2 (>36.4-89.3) and T3 (>89.3)]. Logistic regression analysis was used to examine the association between baseline physical activity levels and the incidence of depressive symptoms during the school years.@*Results@#In the 3year followup (2018-2020), 852 (60.2%) participants exhibited depressive symptoms. The numbers of individuals with depressive symptoms in the T1, T2, and T3 groups were 324, 268, and 260, respectively. Logistic regression analysis showed that college students who participated in higher levels of physical activity decreased the risk of depressive symptoms by 34.2% [T2: OR(95%CI) = 0.658 (0.500-0.866)] and 38.9% [T3:OR(95%CI)=0.611(0.465-0.804)] compared with T1 group after adjusting for demographic, lifestyle, healthrelated factors, and baseline depressive symptoms as covariates. The sexstratified analysis showed a negative correlation between physical activity levels and the incidence of depressive symptoms in female college students. Compared with T1 group, higher levels of physical activity reduced the incidence of depressive symptoms by 39.6% [T2: OR(95%CI)=0.604(0.445-0.820)] and 37.7% [T3: OR(95%CI)=0.623(0.459-0.846)], respectively (P<0.01). However, there was no significant correlation between physical activity levels and depressive symptoms in male college students (P>0.05).@*Conclusions@#There is an inverse relationship between physical activity levels and depressive symptoms. The findings suggest that schools should reduce the risk of depressive symptoms by promoting physical activity levels among college students.

Relationship among screen time，depressive symptoms and sleep parameters among college students / 中国学校卫生

Objective@#To explore the relationship between daytime or nighttime screen time, sleep duration, bedtime, sleep quality and depressive symptoms, so as to provide reference for preventing depression symptoms in college students.@*Methods@#A total of 1 259 college students in one university in Beijing were recruited by using a cluster random sampling method for online and offline questionnaire surveys in October 2022 and April to May 2023. The sleeping quality, depression symptoms and screen time of participants were measured with the Pittsburgh Sleep Quality Index(PSQI), Chinese Version of the Beck Depression Inventory-II (BDI-II-C) and Screen Time Questionnaire. Logistic ordered regression and multiple linear regression were used to analyze the correlation among screen time, sleep parameters and depressive symptoms.@*Results@#The prevalence of depressive symptoms was 24.9 %. There was no significant correlation between daytime screen time and depressive symptoms for a week after controlling for night screen time in a week, gender and age ( OR= 1.00 , 95%CI=1.00-1.01, P >0.05). There was a significant correlation between night screen time and depressive symptoms for a week ( OR=1.05, 95%CI=1.03-1.06, P <0.01) after controlling for daytime screen time in a week, gender and age. However, after controlling for the weekday sleep duration, weekend bedtime, and sleep quality step by step, there was no significant correlation between the night screen time for a week and the depressive symptoms ( OR=1.01, 95%CI= 0.99 -1.02, P >0.05). After adjusting for gender and age, multiple linear regression analysis found that the duration of one week s night vision screen had statistical significance in predicting weekday sleep duration, weekend sleep time and sleep quality ( β=-0.29, 0.45, 0.26, P <0.05). There were positive correlation between the duration of sleep on study days, the duration of sleep on rest days, and the quality of sleep with depressive symptoms（ OR =1.27,1.39,1.45， P <0.01）.@*Conclusions@#Excessive night screen time has a greater impact on sleep problems and depressive symptoms. Reducing nighttime video and improving sleep habits are potential intervention goals for reducing depression symptoms in college students.

Associations of family functioning and parental styles with anxiety symptoms among high grade primary school students / 中国学校卫生

Objective@#To investigate the prevalence of anxiety symptoms among high grade primary school students in Guangzhou and their correlation with family functioning and parental parenting styles, so as to provide theoretical basis and guidance for family based interventions for children s anxiety symptoms.@*Methods@#From June to September 2022, a multi stage cluster random sampling method was employed to select 5 396 students from grades 4 to 6 in 13 primary schools in Guangzhou. The Family Functioning Assessment Scale for Children, Parental Bonding Instrument, and Spence Children s Anxiety Scale Short Version were used for the survey. Inter group comparison was analysed by t test or analysis of variance. Linear regression analysis was used to explore the effects of family function and parental parenting styles on anxiety symptoms in primary school students.@*Results@#The average score for anxiety symptoms among high grade primary school students in Guangzhou was (11.63±10.88). In terms of parenting styles, mothers scored higher than fathers in the dimensions of "care" (25.63±4.92) and "control" (5.08±2.58) compared to fathers ( 24.74± 5.50, 5.00±2.51) ( t =15.80, 4.21, P <0.01). However, there was no statistically significant difference in the scores of parents on the dimension of "encouragement of independence"（12.98±4.06,13.05±3.95)( t =-1.77， P >0.05）. After adjusting for general demographic characteristics, the results of linear regression analysis showed that primary school students family functioning ( B =0.47) and parental "control" ( B =0.67, 0.75) were positively associated with anxiety symptoms scores ( P <0.01). Meanwhile, parental "care" ( B =-0.53,-0.55) and "encouragement of independence" ( B =-0.62,-0.68) were negatively associated with anxiety symptom scores ( P <0.01). These associations remained statistically significant even after further adjusting for family functioning ( P <0.01).@*Conclusions@#Family functioning, parenting styles are closely associated with anxiety symptoms among high grade primary school students. Positive family functioning and parenting styles may mitigate childhood anxiety symptoms, whereas excessive parental control may increase the risk of childhood anxiety symptoms.

Association of agression and angry expression category perception under social exclusion among male students in reform school / 中国学校卫生

Objective@#To explore the relationship between aggression and category perception of angry expression in reform school students under social exclusion, so as to provide reference for the reform school students mental health promotion.@*Methods@#In May 2023, 144 students were randomly selected from a reform school in Guizhou Province, and were divided into high and low aggression groups(77 and 67 students) by Aggression Questionnaire. Cyberball game was used to induce social exclusion and acceptance, subjects were divided into high aggressive exclusion group ( n =42), high aggressive acceptance group ( n =35), low aggressive exclusion group ( n =37) and low aggressive acceptance group ( n =30). All the participants completed the discrimination and identification tasks of category perception paradigm, and the relationship between aggression and category perception of angry expression of reform school students under social exclusion was analyzed by using category turning point, identification curve and analysis of variance.@*Results@#The total score of aggression(97.34±8.00) and four dimensions (physical aggression: 29.75± 4.61, verbal aggression:17.19±2.58, anger:22.29±3.66, hostility:28.10±3.54) in the high aggression group were higher than those in the low aggression group(74.10±9.02，21.09±4.98，14.30±2.66，17.16±3.83，21.55±3.88), and the differences were statistically significant ( t =16.38, 10.85, 6.62, 8.20, 10.59, P <0.01). For identifying the turning point of the fear anger continuum, the social exclusion group（2.58±0.07）was significantly smaller than the social acceptance group（2.79±0.07）( F =4.85, η 2=0.07, P < 0.05 ）, and the social exclusion group had a tendency to shift the category boundary to the fear side. For identifying the slope at the angry happiness continuum category boundary curve, the high aggression group (0.63±0.03) was significantly higher than the low aggression group (0.53±0.03)( F =5.38, η 2=0.08, P <0.05). In the fear anger continuum,the high aggression group[(694.86± 78.29 )ms] reacted more quickly than the low aggression group[(660.70±79.86)ms]( F =5.08, η 2=0.05， P <0.05) In the angry happiness continuum, there was no statistical significance of social exclusion and aggression( P >0.05).@*Conclusions@#The suggests that social exclusion can lead to hostility attribution bias in individuals, while aggression can make individuals more sensitive to angry expression. The mechanisms by which social exclusion and aggression affect expression category perception are independent rather than interactive. The society should give tolerance and acceptance to reform school students, reduce exclusion and discrimination, and the reform education department should correct the aggressive behavior of reform school students and promote their mental health.

Relationship between ruminative thinking, life events and learning value doubt among junior high school students / 中国学校卫生

Objective@#To explore the mediating effect of rumination between life events and learning value doubt among junior high school students, so as to provide reference for the psychological health education of junior high school students.@*Methods@#From March to July 2023, a total of 930 junior high school students from Guangdong, Jiangsu and Hebei were selected by a combination of convenient sampling methods. Participants completed the Scales of Value of Learning (SVL), Ruminative Response scale (RRS) and Adolescent Self rating Life Events Checklist (ASLEC). The t test and ANOVA were used for inter group comparisons and Pearson correlation analysis was used for correlation analysis and bootstrap method was used for mediating effect test.@*Results@#The life events of junior middle school students were positively correlated with learning value doubt ( r =0.18), rumination ( r = 0.65 ) and its three dimensions (brooding, reflective pondering, and symptom focused rumination) ( r =0.60, 0.59, 0.66). Learning value doubt was positively correlated with rumination ( r =0.15) and its three dimensions ( r =0.07, 0.13, 0.19) ( P <0.05).The symptom focused rumination (effect size=0.09, 95% CI =0.06-0.11) and brooding (effect size=-0.07, 95% CI =-0.09--0.04) dimensions partially mediated the relationship between life events and learning value doubt. In the two influential pathways, symptom focused rumination exerts a stronger impact, and the difference was statistically significant (effect size=0.15, 95% CI =0.11- 0.20 , excluding 0) ( P <0.05).@*Conclusions@#Life events experienced by junior high school students can positively predict learning value doubt through symptom focused rumination, and negatively predict learning value doubt through brooding. Active attention should be paid to the mental health status of junior high school students, intervene promptly when they experience life events, reduce symptom based rumination, and improve their learning enthusiasm.

Objective@#To explore the effects of happy physical education based on constructivism on physical education learning burnout, body shape and mental health of college students, so as to provide a reference for the reform of physical education teaching in universities.@*Methods@#By using cluster sampling method, students from two teaching classes of the 2022 physical badminton elective course were enrolled as the research objects at Shanghai Institute of Commerce and Foreign Languages from September to December 2022. They were randomly divided into experimental group ( n =38) and control group ( n =40) by drawing lots. The control group received routine physical education teaching for 16 weeks, with 2 class hours weekly and 45 minutes per class hour. While the experimental group was given happy physical education based on constructivism, with a teaching process of building a framework, independent exploration, collaborative learning, and effect evaluation. The idea was to integrate Happy Sports into badminton technology and tactical training courses, emphasizing the fun of sports activities, and drawing on various forms of sports games when designing sports activities. Two groups of students were tested for body shape, surveyed with the Physical Education Learning Burnout Scale and Symptom Check List-90 (SCL-90). The scores of Physical Education Learning Burnout Scale, body mass index (BMI), waist to hip ratio, body fat rate and SCL-90 were compared between the two groups by t-test, Chi-square test and Fisher s exact probability test.@*Results@#At the end of the semester, BMI [(21.58±1.59,22.30±1.46)kg/m 2], waist to hip ratio (0.75±0.08, 0.79 ±0.07) and body fat rate [(19.77±2.50)%,(21.02±2.46)%] in experimental group were lower than those in control group ( t= -2.09, -2.35, -2.23, P <0.05). The scores of depression (15.10±3.92,17.24±4.18), improper behaviors (13.60±3.05,15.48± 3.52 ) and low sense of achievement (5.52±1.36,6.54±1.42) and total score of Physical Education Learning Burnout Scale ( 34.22± 7.55,39.26±7.86) in experimental group were lower than those in control group ( t=-2.33, -2.52, -3.24, -2.89, P <0.05). The scores of somatization (16.27±3.75,18.57±4.12), interpersonal sensitivity (14.30±4.57,16.85±4.21), depression (17.02±3.89,19.36±4.28) and anxiety (12.68±3.96,15.32±3.87), and total scores of SCL-90 (127.87±22.54,140.54±25.83) in experimental group were lower than those in control group ( t=-2.57, -2.57, -2.52, -3.00, -2.30, P <0.05).@*Conclusions@#The happy physical education mode based on constructivism can alleviate learning burnout, improve mental health and optimize body shape of college students. Appropriate reforms should be made to the teaching mode of physical education in universities to promote the physical and mental health development of college students.
