The prevalence of overweight and obesity: a measurement-based analysis of 6-9-year-old school children from Montenegro.

Introduction: This study aimed to conduct a measurement-based analysis of overweight and obesity prevalence among 6-9-year-old children in Montenegro. Methods: The population of this cross-sectional study included 1993 (1059 boys and 934 girls) primary-school children. The sample of anthropometric variables includes body height, body weight and body mass index, as well as nutrition status that were presented based on BMI standardized categories: underweight, normal weight, overweight, and obesity. The descriptive statistics described the means for each variable, while post hoc tests and ANOVA were applied to explore differences between the proposed means. Results: The results indicate the overweight (including obesity) prevalence was 28% (15% of overweight and 13% of obese children), while boys have a higher overweight prevalence rate than girls. In addition, the tendency of higher prevalence rates to differ by age in both sexes is observed. This study also confirmed that overweight and obesity are affected by geographical regions but not by the level of urbanization in Montenegro. Discussion: The innovation of this study is reflected in the fact that the overweight and obesity prevalence rates among 6-9-year-old children are within an acceptable range in Montenegro, since it does not deviate from the European average, but further interventions and continuous monitoring are necessary, due to the specific nature of this issue.

How digital health technologies promote healthy life in the Post-COVID-19 Era: evidences from national survey on Chinese adolescents and youngsters.

The rapid development of intelligent technologies coupled with the stay-at-home trends in the Post-COVID-19 Era has significantly changed youth's health behavior as well as reshaped their lifestyles. Digital health technologies (DHTs) have been more and more used for health management among youngsters. However, little was known about the use of DHTs among youths and its consequences on their health, especially in developing countries like China. Inspired by behavior intervention technology (BIT) model, this study examined the underlying mechanisms of use and social interactions of DHTs on Chinese adolescents' and youngsters' healthy lifestyles and mental health, using a representatively national survey among high school and freshman students in China (N = 2,297). It found that use of DHTs had a significantly positive effect on Chinese youths' healthy lifestyles and mental health, with behavioral regulation as a mediator. However, social interactions of DHTs were negatively associated with their mental health. The findings contribute to a better guidance on health promotion, as well as the enhanced design of DHTs' products.

Emotion regulation strategies and aggression in youngsters: The mediating role of negative affect.

Aggression in youngsters is a highly prevalent problem worldwide. Given that this problem has negative consequences for society, aggressors, and victims, the present study aims to understand the processes underlying the acts of aggression in this population. Specifically, we analyze the role of two emotional regulation strategies (cognitive reappraisal and expressive suppression) and the positive and negative affect variables in aggressive behavior. For this purpose, 654 primary and high school students aged between 9 and 18 years (47.6% boys) were assessed on emotion regulation, positive and negative affect, and aggression through the Emotion Regulation Questionnaire, the Positive and Negative Affect Schedule, and the Buss-Perry Aggression Questionnaire, respectively. The results revealed that higher use of the cognitive reappraisal strategy was correlated with lower levels of aggression (for total, physical, and anger). In contrast, the opposite was observed with expressive suppression (for total aggression and hostility). More important for the purposes of this study was the finding that the negative affect variable mediated the relationship between expressive suppression and aggressive behavior. Specifically, those individuals who made greater use of the expressive suppression strategy had higher levels of negative affect, which, in turn, was associated with higher levels of aggression. Cognitive reappraisal appeared to be only directly related with a reduction in total aggression. Thus, higher levels of cognitive reappraisal were related to a reduction in aggressive behavior. However, when focusing on the four dimensions of aggression, the relationship between cognitive reappraisal and aggression appears to be mediated by negative affect and, in the case of anger, by positive affect. The limitations and implications of these findings are discussed.

The reciprocal interplay of physical activity and health-related quality of life in children and adolescents: Evidence for both upward and downward spirals.

OBJECTIVE: This study examines the bidirectional effect between physical activity (PA) and health-related quality of life in children and adolescents, focusing on within-person effects. METHODS: PA and health-related quality of life were assessed in children and adolescents (N = 685, age: M = 10.29 years, SD = 1.35, range = 8-14), via self-report across four waves, each 6 months apart, and a random-intercept cross-lagged panel model with time-invariant cross-lagged effects was calculated. RESULTS: Positive cross-lagged effects between prior PA and health-related quality of life 6 months later ( γ y = 0.536, 95% CI [0.016, 1.055], p = .043, d = 0.11) and vice versa ( γ x = 0.015, 95% CI [0.001, 0.030], p = .039, d = 0.12) were found. Furthermore, the random intercept correlation was significant ( T xy = 3.622, 95% CI [2.204, 5.041], p < .001, d = 0.27). CONCLUSIONS: The findings confirm known correlations between PA and health-related quality of life and extends them by indicating both an upward and downward spiral of PA and health-related quality of life in children and adolescents.

Does Regular Exercise Impact the Lung Function of Healthy Children and Adolescents? A Systematic Review and Meta-Analysis.

PURPOSE: To assess the quality of the available evidence on the effect of exercise for the improvement of lung function in healthy children and adolescents. METHOD: We performed a systematic review and meta-analysis of intervention studies examining the effects of regular exercise on spirometric parameters of healthy children and adolescents aged ≤18 years. RESULTS: Within the exercise groups, there were significant improvements in forced vital capacity (mean difference: 0.17 L; 95% confidence interval, 0.07 to 0.26; P < .05) and forced expiratory volume in the first second (mean difference: 0.14 L; 95% confidence interval, 0.06 to 0.22; P < .05). Results were consistent across different age groups and duration of interventions. In the between-group analysis, forced vital capacity, forced expiratory volume in the first second, and peak expiratory flow were higher in the exercise group compared with the nonexercise group, but the differences did not reach statistical relevance. There was significant statistical heterogeneity between studies. CONCLUSION: Regular exercise has the potential to improve lung function parameters in healthy children and adolescents; however, the small number of studies and the heterogeneity between them raise concern about the quality of the currently available evidence. These findings bring to attention the need for well-designed trials addressing this important public health issue.

Perception and assumptions of young waterpipe smokers in Mumbai, India.

Background: Hookah smoking has been on raise all over the world, including India, especially among youngsters. There is growing evidence suggesting the high school children experimenting this form of tobacco. Objective: The objective of this study was to investigate the characteristics, behavior, and perceptions related to hookah smoking among the hookah smokers in Mumbai. Materials and Methods: A cross-sectional survey was conducted among 200 randomly selected young adults between the age group of 15-35 years in Mumbai who visited different dental clinics. The questionnaire was distributed as Google Forms online in the month of November and December 2019 and those who submitted completed responses were included in the study. Results: Only 114 participants returned with the completed forms in the time period of 2 months. The results showed that the majority of participants were between 20 and 24 age, comprising 58% who were having the habit of hookah smoking. Among which 24% females, 76% males had history of hookah habit. Eight percent of males started smoking hookah from very young age. Males (29.89%) shared one hookah pot with four members. Forty percent of the participants stated that they are interested to smoke again because of hookah flavor. Conclusion: Easy availability of newer forms of smoking at online markets could play a role in promoting the use of hookah among youngsters. Most products are being sold without any warnings, and there is no means to control the selling of the products to minors. Educational intervention is urgently needed to create awareness among youth about the harmful effects of hookah smoking.

I Need to Know: Using the CeHRes Roadmap to Develop a Treatment Feedback Tool for Youngsters with Mental Health Problems.

Patient-Reported Outcome Measures (PROMs) are often used to monitor treatment outcomes in youth mental health care. Unfortunately, youngsters are rarely informed about the results of their PROMs or, when they are, it is in an insufficient manner. Therefore, a web application was developed-together with youngsters-aimed at giving them feedback about their PROMs. The aim of this study is to describe the development process of the application. An expert panel consisting of youngsters, web designers and researchers, as well as a representative from a client organisation, developed the e-health application INK (short for 'I Need to Know') in an iterative process based on the Centre for eHealth Research roadmap (CeHRes roadmap). Youngsters prefer, among other aspects, a simple, easy-to-use e-health application with a colourful appearance and want to be able to compare their results across different time points and informants. The INK tool provides youngsters with insight into their PROM results. Based on the youngsters' preferences, INK users can choose which feedback information is visible. INK facilitates youngsters' active participation in their treatment as well as shared decision-making with their professional caregivers.

Analysis of the Financial Costs of a Health Promotion Program for Sexually Exploited Adolescents and Youngsters: The Case of the Vira Vida Program in Brazil.

The Vira Vida program promotes the health of adolescents and young adults, ages 16 to 24, who have been sexually exploited. It has served more than 3000 individuals in 18 Brazilian states. The objective of this research was to estimate the costs of Vira Vida and compare them with the costs of detention policies for juveniles under 18. This program cost study considers two periods: 2008 to 2012 (Cycle 1) and 2013 to 2014 (Cycle 2). The System S perspective and time horizon for one year were adopted. Direct costs incurred by the National Council of Industry Social Services, which coordinates Vira Vida, and by the Regional Departments (RD), responsible for the direct execution of Vira Vida, were analyzed. The cost of detention measures for adolescents and youngsters under the age of 18 was obtained from the literature. The annual cost per student enrolled in Vira Vida varied between US$ 3754.93 and US$27,244.48, depending on the cycle and the state. Most of the costs of the program were lower than those reported for detention measures for adolescents in Brazilian states. Evidence indicates that health promotion interventions targeting sexually exploited children and adolescents can help their recovery; on the other hand, studies indicate that detention measures do not help adolescents recover.

Jovem Nem Nem: Questionamentos a partir de Pesquisas sobre Juventude e Experiências de Jovens Pobres / NEEt Youth: Questions from Research on Youth and the Experiences of Poor Youngsters / Joven NiNi: Cuestionamientos a partir de Investigaciones sobre Juventud y Experiencias de Jóvenes Pobres

Os/as chamados/as jovens nem nem são os/as que nem estudam, nem trabalham, nem procuram emprego. Analisamos sua construção como problema social a partir de um tripé: o desconhecimento e desinteresse pelas experiências dos/as jovens pobres, a espetacularização do fenômeno e a constituição de um conjunto de práticas para solucioná-lo. As análises apresentadas partem de uma pesquisa que realizou, com o auxílio do programa ALCESTE, uma análise lexical de universos semânticos sobre os/as chamados/as jovens nem nem em 19 documentos da Organização Internacional do Trabalho/OIT, e uma pesquisa-intervenção com 14 jovens. Analisamos como as microrrelações, as macropolíticas, os aspectos institucionais e culturais contribuem para a ausência dos/as jovens na escola e no trabalho, o que se contrapõe às noções de que os investimentos necessários para a resolução do problema construído devem se dirigir, exclusivamente, à dimensão individual. Problematizamos as noções que convidam a pensar os/as jovens ditos/as nem nem como sujeitos vulneráveis e como grupo de risco, e destacamos sua construção como simulacro dos/as jovens que têm seus direitos negados cotidianamente.

The so-called NEET youngster consists in those who neither study, nor work, nor search for employment. We analyze its construction as a social problem from a tripod: the unknowing and disinterest of poor youngster's experiences, the glamorization of the phenomena and the constitution of a group of practices to solve it. The analyzes presented are based on research that carried out a lexical analysis of semantic universes, using as support the ALCESTE program, about the so-called NEET youngster in nineteen (19) documents of the International Work Organization/OIT, and an intervention-research with fourteen (14) young. We had analyzed how micro-relations, the macro-politics, the institutional and cultural aspects contribute to the absence of the youngsters from school and work, which are opposed to the notions that needed investments to solve the built-up problem must come exclusively from individual dimension. We had problematized the notions that consider the thought of NEET youngsters as vulnerable individuals and as a risk group, and we highlight its construction as a simulation of youngster which has his/her rights denied daily.

Los/las llamados/as jóvenes nini son los/las que ni estudian, ni trabajan, ni buscan empleo. Analizamos su construcción como problema social a partir del trípode: el desconocimiento y desinterés por las experiencias de los/las jóvenes pobres, una espectacularización del fenómeno y la constitución de un conjunto de prácticas para solucionarlo. Los análisis presentados parten de una investigación que realizó un análisis lexical de universos semánticos, usando como apoyoel programa ALCESTE, sobre los/las llamados/as jóvenes nini en diecinueve (19) documentos de la Organización Internacional del Trabajo/OIT, y una investigación-intervención con catorce (14) jóvenes. Analizamos cómo las microrrelaciones, las macropolíticas y los aspectos institucionales y culturales contribuyen al absentismo escolar y laboral de los jóvenes, lo que se opone a la idea de que las inversiones necesarias para resolver el problema construido deben dirigirse exclusivamente a la dimensión individual. Problematizamos las nociones que invitan a pensar los/las jóvenes dichos/as nini como sujetos vulnerables y como grupo de riesgo, y destacamos su construcción como un simulacro de los/las jóvenes que tienen sus derechos negados cotidianamente.

Investigating oral and systemic pathways between unhealthy and healthy dietary patterns to periodontitis in adolescents: A population-based study.

AIM: To investigate pathways between unhealthy and healthy dietary patterns and periodontitis in adolescents (18-19 years of age). MATERIALS AND METHODS: This population-based study (n = 2515) modelled direct and mediated pathways (via biofilm and obesity) from patterns of healthy diet (fruits, fibre, vegetables, and dairy) and unhealthy diet (sugars, snacks, and salty/fast foods) with initial periodontitis (bleeding on probing [BoP], probing depth [PD] ≥ 4 mm, clinical attachment loss [CAL] ≥ 4 mm), moderate periodontitis (BoP, PD ≥ 5 mm, and CAL ≥ 5 mm), and European Federation of Periodontology and the American Academy of Periodontology (EFP-AAP) periodontitis definitions, adjusting for sex, socio-economic status, smoking, and alcohol, through structural equation modelling (α = 5%). RESULTS: Higher values of healthy diet were associated with lower values of initial periodontitis (standardized coefficient [SC] = -0.160; p < .001), moderate periodontitis (SC = -0.202; p < .001), and EFP-AAP periodontitis (p < .05). A higher value of unhealthy diet was associated with higher values of initial periodontitis (SC = 0.134; p = .005) and moderate periodontitis (SC = 0.180; p < .001). Biofilm mediated the association between higher values of unhealthy diet and all periodontal outcomes (p < .05). CONCLUSIONS: Our findings suggest that both healthy and unhealthy dietary patterns may contribute to reduced or increased extent and severity of periodontitis by local and systemic mechanisms, preceding the effect of other established causes such as smoking and obesity, in younger population.

Microsurgical treatment of symptomatic vestibular schwannomas in patients under 40: different results before and after age of 30.

In 10-15% of cases of vestibular schwannoma (VS), age at diagnosis is 40 years or less. Little is known about the differences in natural history, surgical findings, and postoperative outcomes of such younger patients as compared to those of greater age. To analyze clinical and surgical and imaging data of a consecutive series of n = 50 patients with unilateral sporadic VS, aged 40 years or younger - separated in a very young group (15-30 years) and a moderately young group (31-40 years). Retrospective case series. Fifty consecutive patients under 40 years of age underwent microsurgical resection of unilateral sporadic VS via the retrosigmoid approach. The study cohort was subdivided into two groups according to the age range: group A, age range 15-30 years (n = 23 patients), and group B, age range 31-40 years (n = 27 patients). The adherence of VS capsule to surrounding nervous structures and the tendency of the tumors to bleed were evaluated by reviewing video records; the course of the FN in relation to the tumor's surface was assessed in each case. Microsurgical removal of tumor was classified as total (T), near total (residual tumor volume < 5%), subtotal (residual tumor volume 5-10%), or partial (residual tumor volume > 10%). Mean tumor size of entire cohort was 2.53 (range: 0.6-5.8) cm: 2.84 cm in group A and 2.36 cm in group B (p = NS). Facial nerve course and position within the cerebellopontine angle did not differ significantly between the two groups. At 6-month follow-up, FN functional outcome was HBI-II in 69.5% in group A, versus 96.3% in group B (p < .001). Hearing preservation was achieved in 60.0% of patients of group A and in 58.3% of group B (p = NS). Total and near-total resection was feasible in 95.6% of cases of group A and in 88.9% of group B (p = NS). Tumor capsule was tightly adherent to nervous structures in 69.6% patients of group A and in 22.2% of group B (p < .05). Significant bleeding was encountered in 56.5% of group A tumors, and in 29.6% of group B tumors (p < .01). Microsurgery of VS in patients aged 40 or less is associated with good functional results, and with high rates of total and near total tumor removal. Patients < 30 years of age have more adherent tumor capsules. Furthermore, their tumors exhibit a tendency to larger sizes, to hypervascularization, to profuse intraoperative bleeding and they present worse long-term functional FN results when compared to patients in their fourth decade of life. Our limited experience seems to suggest that a near total resection in very young VS patients with large tumors should be preferred in adherent and hypervascularized cases, in order to maximize resection and preserve function.

Whole-blood magnesium and blood lipids are individually and jointly associated with an elevated likelihood of youngsters being overweight or obese: A matched case-control study using the propensity score.

OBJECTIVES: Youngsters who are overweight or obese (YOO) have become an important global health concern. Some micronutrients may be modifiable influential factors. This study aimed to investigate the individual and joint association of whole-blood magnesium (WBMg) and total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), or high-density lipoprotein cholesterol (HDL-C) in YOO. METHODS: This is a propensity score matching-based case-control study. YOO was defined depending on age- and sex-specific body mass index z-score, calculated with SAS macros (%group_standard and %WHO2007) from the World Health Organization website. WBMg, blood lipids, and covariates were carefully measured by trained technicians using a whole-blood, five-element, basic analyzer and atomic absorption spectrometer or automatic biochemical analyzer. Locally weighted scattered plot smoothing and multivariable conditional logistic regression models were applied to estimate the associations of WBMg and blood lipids in YOO. RESULTS: WBMg was positively associated with YOO. The adjusted likelihood of YOO significantly increased by 21% (odds ratio: 1.21; 95% confidence interval [CI], 1.10-1.33) with per-interquartile range elevation of WBMg. Compared with the 1st quartile, adjusted odds ratios among youngsters in the 2nd, 3rd, and 4th quartiles of WBMg were 1.11 (95% CI, 0.92-1.35), 1.29 (95% CI, 1.06-1.57), and 1.47 (95% CI, 1.18-1.83), respectively. Furthermore, the relationship between WBMg and YOO was moderated by lipid profiles. Compared with those having lower (< median) WBMg and TC, TG, LDL-C, or higher (≥ median) HDL-C, youngsters with both higher WBMg and TC, TG, LDL-C, or lower HDL-C had higher YOO odds, which averagely increased by 188%, 250%, 339%, and 369%, respectively. CONCLUSIONS: WBMg was an independent risk factor of YOO, and the associations were stronger among those with unhealthy blood lipids. Our findings can help to guide clinical and public health policies on the relevance of magnesium nutritional status.

Relación entre el uso problemático de Facebook y la evitación experiencial en jóvenes colombianos / Relationship between the Problematic Use of Facebook and Experiential Avoidance in Young Colombians

Resumen Las tecnologias facilitan la comunicación y la interacción e influyen en los comportamientos y actitudes. Sin embargo, pueden causar impacto negativo cuando interneren en las actividades cotidianas y afectan la salud mental, física y social. El objetivo del estudio fue analizar la relación entre el uso problemático de Facebook, la evitación experiencial y los componentes de la teoría biopsicosocial. Estudio de tipo correlacional con diseno transversal no experimental. En total participaron 677 jóvenes colombianos, que diligenciaron de manera voluntaria los cuestionarios de datos sociodemográficos, la escala de Aceptación y Acción-II (AAQ-II) y la escala de Adicción a Facebook de Bergen (BFAS). Los resultados muestran que los hombres presentaron mayor uso problemático de la red social y puntuaron más alto en los componentes de abstinencia y conflicto. Se encontró una relación positiva significativa entre el uso problemático, la evitación experiencial y todos los componentes de la teoría biopsicosocial. En conclusión, la evitación experiencial aporta a la comprensión del uso problemático de Facebook desde el análisis funcional y la teoría Biopsicosocial que orienta en la identificación de la sintomatología adictiva; estos hallazgos permiten direccionar futuras intervenciones.

Abstract Technologies facilitate communication and interaction, and influence behavior and attitudes. However, they can have a negative impact when they interfere with everyday activities that affect mental, physical, and social health. The objective of the study was to analyze the relationship between the problematic use Facebook, experiential avoidance, and components of the biopsychosocial theory. This study was of a correlational type with a non-experimental cross-sectional design. A total of 677 young Colombians participated, who voluntarily filled out the socio-demographic data questionnaires, the Acceptance and Action-II scale (AAQ-II), and the Bergen Facebook Addiction Scale (BFAS). The results show that men present more problematic use of the social network and scored higher on the abstinence and conflict components. A significant positive relationship was found between the problematic use, experiential avoidance, and all components of the biopsychosocial theory. In conclusion, the experiential avoidance contributes to the understanding of the problematic use Facebook from the functional analysis, and the biopsychosocial theory guides in the identification of the addictive symptomatology. These findings allow directing future interventions.

Estimación de la masa grasa por medio de indicadores antropométricos en jóvenes con síndrome de Down / Estimation of fat mass by anthropometric indicators in young people with Down syndrome

Introducción: la evaluación de la composición corporal es relevante y útil para diseñar intervenciones de estilos de vida saludables y estrategias nutricionales.Objetivos: verificar las relaciones existentes entre los indicadores de adiposidad y la masa grasa (MG), y validar ecuaciones que permitan predecir la MG en jóvenes con síndrome de Down (SD).Métodos: se efectuó un estudio transversal en 48 jóvenes con SD (24 hombres y 24 mujeres). Se evaluaron el peso, la estatura, la circunferencia de la cintura (CC) y la circunferencia de la cadera (CCa). Se calcularon el índice de masa corporal (IMC), el índice de adiposidad corporal (IAC), el índice cintura-cadera (ICC) y el índice cintura-estatura (ICE). Se evaluó la MG mediante absorciometría de rayos X de doble energía (DXA). Resultados: la edad de los hombres era de 19,3 ± 3,0 años y la de las mujeres de 18,9 ± 1,9 años; el peso era de 73,6 ± 14,3 kg en los hombres y de 75,8 ± 20,3 kg en las mujeres; finalmente, la estatura de los hombres era de 168,9 ± 6,5 cm y la de las mujeres de 156,3 ± 6,2 cm. En los hombres, las correlaciones entre la MG (DXA) y los parámetros IMC, CC, CCa, ICE, IAC e ICE oscilaron entre r = 0,01 y r = 0,89; en las mujeres, entre r = 0,10 y r = 0,97. Las correlaciones más altas se observaron con el IMC y la CC en ambos sexos (hombres, r = 0,78 a 0,92 y mujeres, r = 0,83 a 0,97). Se generaron ecuaciones de regresión para estimar la MG en los hombres (R2 = 84 %) y en las mujeres (R2 = 96 %). Se calcularon los percentiles de MG según la DXA y con cada ecuación. Conclusiones:hubo correlaciones positivas significativas del IMC y la CC con la MG. Estos indicadores fueron determinantes para desarrollar ecuaciones que estiman la MG de los jóvenes con SD. Los resultados sugieren su uso y aplicación para evaluar, clasificar y monitorizar los niveles de adiposidad corporal en contextos clínicos y epidemiológicos. (AU)

Introduction: the assessment of body composition is relevant and useful for designing interventions for healthy lifestyles and nutritional strategies. Objective: our goal was to verify the relationships between adiposity indicators with fat mass (FM), and to validate equations that allow predicting FM in young people with Down syndrome (SD). Methods: a cross-sectional study was carried out in 48 young people with DS (24 men and 24 women). Weight, height, waist circumference (WC), and hip circumference (HC) were evaluated. Body mass index (BMI), body adiposity index (BAI), waist-to-hip index (WHI), and waist-to-height index (WHtR) were calculated. FM was evaluated by dual energy X-ray absorptiometry (DXA). Results: age in men was 19.3 ± 3.0 years, and in women it was 18.9 ± 1.9 years; weight was 73.6 ± 14.3 kg in men and 75.8 ± 20.3 kg in women, and height in men was 168.9 ± 6.5 cm, and in women it was 156.3 ± 6.2 cm. In males the correlations between FM (DXA) with BMI, WC, HC, WHtR, BAI and WHtR ranged from r = 0.01 to r = 0.89, and in females from r = 0.10 to r = 0.97. The highest correlations were observed with BMI and WC in both sexes (males r = 0.78 to 0.92, and females r = 0.83 to 0.97). Regression equations were generated to estimate FM in males (R2 = 84 %) and in females (R2 = 96 %). Percentiles were calculated for MG per DXA and for each equation. Conclusions: there were significant positive correlations between BMI and WC with FM. These indicators were decisive for developing equations that estimate FM in young people with DS. The results suggest its potential use and application to evaluate, classify and monitor body fat levels in clinical and epidemiological contexts. (AU)

A Systematic Review on TeleMental Health in Youth Mental Health: Focus on Anxiety, Depression and Obsessive-Compulsive Disorder.

Background and Objectives: The Internet is widely used and disseminated amongst youngsters and many web-based applications may serve to improve mental health care access, particularly in remote and distant sites or in settings where there is a shortage of mental health practitioners. However, in recent years, specific digital psychiatry interventions have been developed and implemented for special populations such as children and adolescents. Materials and Methods: Hereby, we describe the current state-of-the-art in the field of TMH application for young mental health, focusing on recent studies concerning anxiety, obsessive-compulsive disorder and affective disorders. Results: After screening and selection process, a total of 56 studies focusing on TMH applied to youth depression (n = 29), to only youth anxiety (n = 12) or mixed youth anxiety/depression (n = 7) and youth OCD (n = 8) were selected and retrieved. Conclusions: Telemental Health (TMH; i.e., the use of telecommunications and information technology to provide access to mental health assessment, diagnosis, intervention, consultation, supervision across distance) may offer an effective and efficacious tool to overcome many of the barriers encountering in the delivery of young mental health care.

Percursos de jovens em contextos de vulnerabilidade social: um estudo longitudinal / Journeys of young people in contexts of social vulnerability: a longitudinal study

Este estudo busca compreender os significados atribuídos por jovens em contextos de vulnerabilidade social aos seus percursos de vida. A pesquisa possui caráter qualitativo e foi realizada com cinco jovens que, em 2012, haviam participado de um documentário que abordava as experiências de vida de adolescentes de uma Escola Aberta. A partir dos relatos dos participantes e do caráter longitudinal deste estudo, constatou-se que as experiências de ingresso no mundo adulto marcadas por situações de violências, riscos, contextos excludentes e de vulnerabilidades dificultam a concretização de seus projetos e trazem particularidades para a vivência desse período de transições. Como considerações finais, salienta-se a importância de investimentos em ações que possam superar os atravessamentos das vulnerabilidades, como uma forma de evitar possíveis estigmas que fazem parte de determinados contextos. Ressalta-se a relevância do caráter longitudinal desta pesquisa, uma vez que, ao ter escutado esses jovens em dois momentos distintos, ampliaram-se as possibilidades de compreensão de seus percursos de vida.

This study seeks to understand the meanings attributed by young people in contexts of social vulnerability to their life paths. The research has a qualitative character and was carried out with five young people who, in 2012, had participated in a documentary that addressed the life experiences of adolescents at an Open School. From the report of the participants and the longitudinal character of this study, it was found that the experiences of entering the adult world marked by situations of violence, risks, exclusionary contexts and vulnerabilities hinder the implementation of their projects and bring particularities to the experience of this period of transitions. As final considerations, the importance of investments in actions that can overcome the crossings of vulnerabilities is highlighted, as a way to avoid possible stigmas that are part of certain contexts. The relevance of the longitudinal character of this research is emphasized, since, by having listened to the young people at two different moments, the possibilities of understanding their life paths were expanded.

Changes in Attitude to Waterpipe Tobacco Smoking among Youngsters in Eastern Province, Saudi Arabia: A Cross-Sectional Study.

BACKGROUND: A growing number of epidemiological evidence suggests a significant increase in waterpipe tobacco smoking, and its potential to become a major public health concern in most Arabic countries, including Saudi Arabia. METHODS: A cross-sectional study was carried out to assess the prevalence of intention to quit among ever users of waterpipe and intention to start among the never users. The study also investigated the barriers that may prevent users from quitting or trigger the nonusers to start waterpipe smoking. The study consisted of 464 university students from Eastern Province, Saudi Arabia. RESULTS: One hundred and sixty-eight (36.2%) participants were responded that they had WTS at least one time in the past. Among the ever users of WTS, 120 (71.4%) participants had made an attempt or more to quit WTS in the past, 64 (38.1%) had made more than one attempt, and nearly two-third expressed the intention to quit WTS in the future. Forty (13.5%) out of 296 never-users expressed their intention to start WTS in the future. The study further showed that peer influence, social acceptance, and risk perception were significant predictors of intention to start or stop WTS among students. CONCLUSION: It is promising that substantial users have the intention to discontinue WTS, though a fraction of never users wish to try WTS in the future.

Fuzzy analysis of students' perception of traffic safety in school environments: the case of a small Brazilian city.

Thousands of lives are lost every year due to traffic accidents worldwide, and youths are the most affected. The goal of this paper is to analyze the differences in young students' perceptions about traffic safety in school surroundings in order to help in the formulation of public policies and the development of infrastructure to make school travels safer. A questionnaire was used to obtain the perception of high school students from institutions with different urban characteristics. Data modelling with fuzzy logic and statistical analysis of variance indicated that students' perceptions are influenced by the different realities these youths are exposed to daily, such as school socioeconomic category, transport mode, urban environment and gender. Traffic engineering measures, public policies and road safety education action, inciting active mobility, can be validated and supported by these results. This road safety analysis may also be a participative alternative for locations with low data access.

Trends in Physical Fitness Among School-Aged Children and Adolescents: A Systematic Review.

Introduction and Objective: This systematic review aimed to analyse the international evolution of fitness with its distributional changes in the performance on tests of physical fitness among school-aged children and adolescents. Methods: In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, the search was undertaken in four international databases (ERIC, PubMed, Scopus, and Web of Science) to identify the studies reporting temporal trends in the physical fitness among school-aged children and adolescents. Results: A total of 485 potential articles were identified, of which 19 articles were relevant for the qualitative synthesis; 1,746,023 children and adolescents from 14 countries (China, Finland, Sweden, Belgium, New Zealand, Denmark, Spain, Norway, Mozambique, Poland, USA, Lithuania, Portugal, Canada), for the period between 1969 and 2017 were included. The subjects were tested using 45 motor tests from eight battery tests. The quality of the study in eight articles was rated as strong, while in 11 articles it was rated as moderate. Discussion: The vast majority of studies show a constant decline in strength and endurance. Three Chinese studies show an increase in strength from 1985 to 1995 and then a decline until 2014. For endurance, similar patterns were found in the two most comprehensive Chinese studies. The decline in flexibility is also evident in European countries. For agility, speed, balance, and coordination, the trend differs among populations.

Representações sociais sobre uso de cannabis entre jovens: estudo comparativo / Social representações of cannabis use among youngsters: comparative study / Representaciones sociales de la cannabis entre los jóvenes: estudio comparativo

Buscou-se identificar e comparar as representações sociais sobre o consumo da maconha na perspectiva de dois grupos de jovens: frequentadores de uma universidade pública, e participantes não-universitários de um projeto social com oriundos de bairros periféricos. Os dados foram coletados em grupos focais, cada um com seis participantes, sendo a análise fundamentada na teoria das representações sociais e operacionalizada pela análise temática. Foram delimitadas categorias a posteriori: imagens da maconha, visão dos familiares, papel/lugar da maconha, motivação/influência para o uso, contexto de uso, posicionamento da escola/universidade e consequências. Observaram-se aproximações entre os grupos sobre a percepção de inocuidade da maconha por ser produto natural e a dificuldade de dialogar a respeito com os familiares, mas também diferenças, por exemplo, quanto a ser ou não a maconha porta de entrada para outras drogas. Discutir sobre a maconha ainda gera resistências e traz tabus, acentuando a necessidade de promoção de diálogos (AU).

We sought to identify and compare the social representations of marijuana use from the perspective of two groups of young people: those attending a public university, and non-university participants attending a social project with people from suburbs. Data were collected in focus groups, each with six participants, and the analysis was based upon the theory of social representations and carried out through thematic analysis. A posteriori categories were delimited: images of marijuana, family members' view, marijuana's role/place, motivation/influence for use, context of use, school/university positioning and consequences. There were similarities between the groups regarding the perception of the safety of marijuana as a natural product and the difficulty of talking about it within the family, but also differences, for example, as to whether or not marijuana is the gateway to other drugs. Discussing marijuana still generates resistance and brings taboos, accentuating the need to promote dialogues (AU).

Se buscó identificar y comparar representaciones sociales del consumo de marihuana desde dos grupos de jóvenes: los que asisten a una universidad pública y los participantes no universitarios en un proyecto social con personas de los barrios periféricos. Los datos se recolectaron en grupos focales, cada uno con seis participantes, y el análisis se basó en la teoría de las representaciones sociales mediante análisis temático. Se delimitaron categorías a posteriori: imágenes de la marihuana, visión de los familiares, rol/lugar de la marihuana, motivación/influencia para el uso, contexto de uso, posicionamiento de la escuela/universidad y consecuencias. Hubo similitudes en cuanto a la percepción de la seguridad de la marihuana y la dificultad de hablar con los familiares, pero también diferencias, por ejemplo, si la marihuana es o no la puerta de entrada. Hablar de la marihuana aún genera resistencias y trae tabúes, lo que acentúa la necesidad del diálogo (AU).
