Abstract Objective: To analyze the tendency of alcoholic beverage consumption among adolescents and young adults at school age according to their sexes. Methods: This is a trend research study in public schools of the municipality of Petrolina, between 2014 and 2016, with 3146 students aged between 12 and 24 years old. The instrument was constituted by socio-economic inquiry and the Youth Risk Behavior Survey. Trends were assessed using the Centers for Disease Control and Prevention recommended approach. The analyses were conducted using logistic regression, with a statistical significance of 0.05. Results: Close to 56% of the adolescents had already tried some alcoholic beverage, most of which had contact after 13 years of age. The prevalence of binge drinking ranged between 17% and 25%. The percentage of girls who tried alcohol before 13 years old remained similar over the three years (p = 0.943). The prevalence of this behavior was stabilized at around 20%. There was a trend to decrease in the prevalence of boys who reported having tried alcohol before 13 years old (p = 0.014). The percentage of boys who reported involvement in binge drinking in the past 30 days remained stable at around 20% over the years (p = 0.951 ). The girls’ data revealed a significant decrease in binge drinking (p = 0.019). Conclusions: The general analysis suggests a trend towards stabilization of consumption among boys, and an increase among girls.

Resumo Objetivos: Determinar a prevalência de uso atual do tabaco e sua associação com fatores sociodemográficos e comportamentos de risco entre adolescentes e jovens escolares, segundo o sexo. Métodos: A amostra foi composta por estudantes da rede estadual entre 12 e 24 anos, que responderam a versão brasileira do questionário Youth Risk Behavior Survey. Os dados foram analisados no SPSS (versão 20.0), por meio da Regressão de Poisson para avaliar a Razão de Prevalência (RP) das variáveis independentes em relação ao desfecho. Foi adotado p < 0,05. Resultados: A análise final foi composta por 1.275 adolescentes, dos quais 716 (56,2%) eram meninas e 559 (43,8%) meninos. A prevalência de consumo atual do tabaco foi de 6,6% entre as meninas e 9,7% entre os meninos. No sexo feminino, consumir álcool nos últimos 30 dias (3,91 [1,54-9,94]) e ter 14 anos ou menos (0,50 [0,26-0,96]) influenciaram o uso atual de tabaco. No sexo masculino, o uso de tabaco nos últimos 30 dias foi influenciado pelo consumo atual de álcool (2,92 [1,21-7,08]) e envolvimento em luta corporal nos últimos 12 meses (2,32 [1,32-4,09]). Conclusão: Embora a prevalência de consumo atual do tabaco tenha sido baixa em ambos os sexos, a população estudada ainda exibe risco, pois o envolvimento em luta corporal no sexo masculino e o consumo atual de álcool em ambos os sexos aumentaram a probabilidade da população se envolver com uso atual do tabaco.

Abstract Objectives: To determine the prevalence of current tobacco use and its association with sociodemographic factors and risk behaviors among adolescents and young students, according to gender. Methods: The sample consisted of students from the state public school network aged between 12 and 24 years, who answered the Brazilian version of the Youth Risk Behavior Survey questionnaire. The data were analyzed in SPSS software (v. 20.0), using Poisson regression to evaluate the prevalence ratio (PR) of the independent variables in relation to the outcome. p < 0.05 was established as the significance level. Results: The final analysis consisted of 1275 adolescents, of whom 716 (56.2%) were girls and 559 (43.8%) were boys. The prevalence of current tobacco use was 6.6% among girls and 9.7% among boys. In females, consuming alcohol in the last 30 days (3.91 [1.54-9.94]) and being 14 years old or younger (0.50 [0.26-0.96]) influenced current tobacco use. In the male gender, tobacco use in the last 30 days was influenced by current alcohol consumption (2.92 [1.21-7.08]) and involvement in physical fighting in the last 12 months (2.32 [1.32-4.09]). Conclusion: Although the prevalence of current tobacco use was low in both genders, the assessed population still presents a risk, since male involvement in physical fighting and current consumption of alcohol in both genders increased the probability of this population becoming regular tobacco users.

Abstract Aims: To verify the effects of flexibility training conducted at different intensities in young adults. Methods: Twenty-one (21) young adults of both genders with no history of surgery, fracture, and/or rheumatic diseases in the lower limbs and hip, were randomly assigned to low intensity (LI) or high intensity (HI) stretching groups. Two researchers were assigned to evaluate the active knee extension range of motion (ROM) of the volunteers and two other researchers were responsible for the training program. The training consisted of a single exercise for the hamstring muscles (biceps femoris, semimembranosus, semitendinosus). Each session consisted of three repetitions of passive static stretching, maintained for the 60s each, with 30s interval between them, and performed three times a week for four weeks. The stretching intensity was based on the Numerical Verbal Scale, the LI group maintained the intensity between 1 and 2, while the HI group between 9 and 10. Three ROM evaluations were performed pre-intervention, after the 6th session and at the end of the 12th session. Results: No difference was observed between the groups that underwent either high- or low-intensity programs. Both groups achieved gains in flexibility after four weeks of training. Conclusions: The study demonstrated that both high- and low-intensity stretching exercises are effective for ROM and there were no differences between them. Therefore, the intensity can be defined by the preference of the therapist or patient.

Abstract Aim: Resistance exercise (RE) is a widely accepted strategy to counteract the effects of aging and chronic diseases on health-related outcomes. Studies have been suggested that RE improves brain and cognitive health. RE with unstable devices (REI) is a neuromotor complexity strategy with the potential to improve strength, power, and balance in onder adults, however, their effects on neurocognitive function in individuals at risk of cognitive decline are poorly understood. Thus, we describe the REI study protocol, a randomized clinical trial design to assess the effects of 12-weeks of REI and RE on neurocognitive functions in older adults with subjective cognitive complaints. Methods: The sample will consist of individuals (aged 65 or older) with subjective cognitive complaints, who will be randomized in one of three experimental groups: control, RE or REI. Participants of the RE group will receive 12-weeks of progressive resistance training (seven exercises structured into 3 sets of 10-15 repetitions maximum, three times per week). Participants of the REI group will receive the same RE protocol performed on unstable devices that promote progressive instability. The control group received a health education program. The primary outcome is a composite score of neurocognitive functions. Secondary outcomes include each separately neurocognitive domain, functional performance, balance, falls-related parameters, cardiovascular and mood variables. The study results will provide information to design a future and larger preventive trial on populations at risk of cognitive decline and dementia, which is imperative in public health terms. Trial registration: Brazilian registry of clinical trials number RBR-4kqs22.

Resumo Objetivo Determinar a prevalência de comportamentos de risco e sua associação com sobrepeso e obesidade em adolescentes escolares. Métodos Trata-se de estudo transversal, realizado em escolas públicas com adolescentes de 12 a 17 anos. Foi utilizado o questionário Youth Risk Behavior Survey. Os percentis do índice de massa corporal foram obtidos utilizando as tabelas do Centers for Disease Control and Prevention. Possíveis associações foram avaliadas usando o teste do χ2 e um modelo de regressão logística binária. Foram calculados os valores de odds ratio e o IC95%. Resultados Foram avaliados 1.169 estudantes, e 33,9% reportaram ter tido relação sexual. Desse grupo, 33% não utilizaram preservativo na última relação sexual, e 32,7% relataram ter tido quatro ou mais parceiros na vida. Considerando o estado nutricional, 15,3% apresentavam sobrepeso ou obesidade. Em relação ao não uso de preservativo, somente foi observada associação com o número de parceiros sexuais na vida (OR: 0,50; IC95%: 0,28-0,88). O número de parceiros sexuais na vida apresentou associação com o sexo masculino (OR: 9,17; IC95%: 4,16-20,22), idade da primeira relação sexual inferior a 13 anos (OR: 2,51; IC95%: 1,23-5,13) e uso de álcool ou drogas antes da última relação sexual (OR: 6,16; IC95%: 2,14-17,73). Conclusão As taxas de comportamento sexual de risco foram altas, e não foi observada sua associação com sobrepeso e obesidade.

Abstract Objective To determine the prevalence of risky sexual behavior and its association with overweight and obesity among adolescent students. Methods This is a cross-sectional study, conducted in public schools with adolescents aged 12 to 17 years. We used the questionnaire Youth Risk Behavior Survey. The body mass index percentiles were calculated by means of table from the Center for Control and Prevention of Diseases. Possible associations were assessed using the χ2 test and binary logistic regression model. The odds ratio and 95%CI were calculated. Results We evaluated 1,169 students, and 33.9% reported having had sexual intercourse. Of those, 33% did not use a condom during their last intercourse, and 32.7% had had four or more sexual partners thus far. Regarding nutritional status, 15.3% were overweight or obese. In relation to the non-use of condoms, we observed only an association with the number of lifetime sexual partners (OR: 0.50; 95%CI: 0.28-0.88). The number of lifetime sexual partners was associated with males (OR: 9.17; 95%CI: 4.16-20.22), sexual debut age at 13 years or less (OR: 2.51; 95%CI: 1.23-5.13) and drinking alcohol or using drugs before the last intercourse (OR: 6.16; 95%CI: 2.14-17.73). Conclusion Risky sexual behavior rates were high and no association was found between risky sexual behaviors and overweight and obesity.

RESUMO JUSTIFICATIVA E OBJETIVOS: A discinese escapular tem sido associada a lesões e dor no ombro, no entanto essa relação em adolescentes atletas ainda não é bem definida. O objetivo deste estudo foi avaliar a prevalência de discinese escapular em adolescentes atletas amadores e sua associação com a dor e medidas de função no ombro. MÉTODOS: 178 adolescentes do sexo masculino (14,58±2,16 anos) participaram do estudo. Os sujeitos responderam ao questionário Quick Disability Arm Shoulder Hand. Também foram avaliados massa corporal, estatura, rotação interna do ombro e Closed Kinetic Chain Upper Extremity Stability. Para avaliação da discinese escapular, utilizou-se o método visual dinâmico. A regressão logística binária foi utilizada para analisar a associação entre discinese e as demais variáveis. A comparação entre os grupos com e sem discinese foi feita pelo teste te Mann-Whitney, sendo aceito significância estatística quando p<0,05. RESULTADOS: A prevalência de discinese foi de 56,7% e essa condição não teve associação com dor no ombro. Atletas mais jovens têm 159% mais chances de apresentar discinese, enquanto aqueles que treinam mais de uma hora por dia, durante três vezes por semana, têm 77% mais chances de ter o mesmo desfecho. Nenhuma diferença na função do ombro foi encontrada. CONCLUSÃO: A discinese escapular não está associada à dor e não altera medidas de função no ombro em adolescentes atletas. Modalidade, idade e volume de treinamento parecem induzir mudanças na movimentação escapular.

ABSTRACT BACKGROUND AND OBJECTIVES: Scapular dyskinesis has been associated to shoulder injuries and pain. However, this relationship with adolescent athletes is not well established. The objective of this study was to evaluate scapular dyskinesis in young athletes and its association with pain or shoulder function. METHODS: 178 male adolescent athletes (14.58±2.16 years) were evaluated. The subjects completed the Quick Disability Arm Shoulder Hand questionnaire. Body mass, height, shoulder internal rotation and Closed Kinetic Chain Upper Extremity Stability test were measured. A dynamic visual method was applied to assess dyskinesis. Binary logistic regression was applied to analyze the association between dyskinesis and other variables. The comparison between groups with and without dyskinesis was made by the Mann-Whitney andt-test, accepting a statistical significance of p<0.05. RESULTS: The dyskinesis prevalence was 56.7% and this condition was not associated with shoulder pain. Younger athletes are 159% more likely to have dyskinesis, while those who practice more than one hour a day for three times a week are 77% more likely to have the same outcome. No difference in shoulder function was found. CONCLUSION: Scapular dyskinesis is not associated with pain and does not affect shoulder function in adolescent athletes. Sports modality, age and training volume seem to induce changes in scapula movement.

Psychological distress is among the main causes of the onset or worsening of pain symptoms in young sports people. The increasing participation of adolescents in various sports increases the need to verify the prevalence and association of these affective disorders such as anxiety, stress and depression with pain in the shoulder girdle and in the cervical region that are typical in sportspeople who use more frequently the upper limbs. The sample (n = 310; 14.16±2.12 years). Corlett's body diagram and the Brazilian short version of the anxiety, depression and stress scale (DASS-21) were used. Independent t-tests, chi-square and multiple logistic regression were used. The girls had a higher prevalence of anxiety/stress (62%, p = 0.02). The variables associated with anxiety/stress were female (OR = 2.16), aged 15 to 19 years (OR = 2.39) and individual modality (OR = 1.88). The variables associated with depression were age 15 to 19 years (OR = 1.74), individual modality (OR = 1.84) and pain in the shoulder girdle and cervical region (OR = 2.33).

RESUMO Objetivo: Verificar a prevalência de má qualidade de sono e sua associação com características pessoais e sintomas de depressão, ansiedade e estresse em adolescentes atletas amadores. Métodos: Foram avaliados 309 adolescentes atletas, entre 10 e 19 anos. Para a coleta de dados foram utilizados: questionário estruturado, contendo informações pessoais; Índice de Qualidade do Sono de Pittsburgh (PSQI); e Escala de Ansiedade, Depressão e Stress de 21 itens (EADS-21). Na análise descritiva foram calculados a média e o desvio padrão das variáveis numéricas e as frequências absolutas e relativas das variáveis categóricas. Para a análise inferencial foram realizados teste t de Student e teste do qui-quadrado, além de regressão de Poisson, sendo calculadas as razões de prevalência (RP) em um intervalo de confiança de 95% (IC95%). Resultados: A média de idade dos participantes foi de 14,1±2,1, sendo 13,8±2,0 para o grupo de adolescentes com boa qualidade do sono e 15,0±2,1 para o grupo com má qualidade do sono. A má qualidade do sono foi registrada em 28,2% (n=87), a depressão, em 26,9% (n=83) e a ansiedade/estresse, em 40,1% (n=124) da amostra. A má qualidade do sono se associou à faixa etária de 15 a 19 anos (RP 1,24; IC95% 1,14-1,37), a adolescentes com sobrepeso (RP 1,12; IC95% 1,01-1,24) e com sintomas de depressão (RP 1,23; IC95% 1,08-1,40) e de ansiedade/estresse (RP 1,16; IC95% 1,04-1,28). Conclusões: A presença de sobrepeso e sintomas psicológicos, bem como a idade superior a 15 anos, se mostraram fatores de risco para aumentar a chance da má qualidade do sono em adolescentes atletas.

ABSTRACT Objective: To verify the prevalence of poor sleep quality and its association with personal characteristics and symptoms of depression, anxiety and stress in amateur adolescent athletes. Methods: 309 adolescent athletes aged between 10 and 19 years were enrolled. Data collection included: a structured questionnaire, with personal information; the Pittsburgh Sleep Quality Index (PSQI); and the Depression, Anxiety and Stress Scale (DASS-21). Results are described in mean and standard deviation (numeric variables) and absolute and relative frequencies (categorical variables). For the inferential analysis, Student’s t-test and chi-square test were performed, in addition to Poisson regression. Prevalence ratios (PR) were calculated in a 95% confidence interval (95%CI). Results: The mean age of participants was 14.1±2.1, being 13.8±2.0 and 15.0±2.1, respectively, for those with good and poor sleep quality. Poor sleep quality was recorded in 28.2% (n=87), depression in 26.9% (n=83) and anxiety/stress in 40.1% (n=124). Poor sleep quality was associated with ages between 15 and 19 years (PR 1.24; 95%CI 1.14-1.37), overweight (PR 1.12; 95%CI 1.01-1.24) and psychological symptoms of depression (PR 1.23; 95%CI 1.08-1.40) and anxiety/stress (PR 1.16; 95%CI 1.04-1.28). Conclusions: The presence of overweight and psychological symptoms and the age over 15 years were risk factors for increasing the likelihood of poor sleep quality in adolescent athletes.

Resumo Objetivos: determinar a prevalência e fatores associados a gravidez de repetição rápida (GRR) em gestantes adolescentes. Métodos: estudo transversal desenvolvido com gestantes adolescentes assistidas nas Estratégias de Saúde da Família de Caruaru-PE no período de março a agosto de 2013. Foi utilizado um questionário com características sociodemográficas, econômicas, escolares, ginecológicas, obstétricas e contraceptivas. Os dados foram analisados no Statistical Package for the Social Sciences (SPSS), versão 20. Empregou-se modelos de regressão logís-tica binária. Resultados: dentre as 204 gestantes adolescentes entrevistadas, foram analisados os dados de 26,5% (n=54) que eram multigestas. A ocorrência de GRR foi de 42,6% (n=23) [IC95% 29,23-56,79]. As variáveis associadas à GRR foram não uso de métodos contracep-tivos [OR 7,40 (IC95% 1,56-3,49)] e não planejamento da gravidez anterior [OR 0,19 (IC95% 0,05-0,78)]. Conclusões: foi elevado o percentual de GRR nas adolescentes. O não uso de métodos contraceptivos aumentou as chances de GRR, enquanto a não realização de planejamento da gestação anterior diminuiu as chances das adolescentes engravidarem novamente sem programação prévia.

Abstract Objectives: to determine the prevalence and factors associated with the rapid repeat pregnancy (RRP) in pregnant adolescents. Methods: a cross-sectional study was carried out with pregnant adolescents assisted at the Family Health Strategies in Caruaru-PE from March to August 2013. A questionnaire with sociodemographic, economic, schooling, gynecological, obstetric and contraceptive characteristics was used. The data were analyzed in the Statistical Package for Social Sciences (SPSS), version 20. Binary logistic regression models were used. Results: among the 204 pregnant adolescents interviewed, the data of 26.5% (n = 54) multiparous were analyzed. The occurrence of RRP was 42.6% (n = 23) [95% CI 29.23-56.79]. The variables associated with RRP were non-use of contraceptive methods [OR 7.40 (CI95% 1.56-3.49)] and no previous pregnancy planning [OR 0.19 (95% CI 0.05-0.78)]. Conclusions: the percentage of RRP in adolescents was high. The non-use of contracep-tive methods increased the chances of RRP, while the no previous pregnancy planning decreased the chances of adolescents getting pregnant again without previous program-ming.

Resumo O objetivo deste trabalho foi analisar a tendência da completitude dos dados de violência perpetrada contra adolescentes registrados em Pernambuco, em 2009-2012. Estudo transversal, com 5.259 adolescentes vítimas de violência notificadas no SINAN-VIVA da Secretaria Estadual de Saúde de Pernambuco. Utilizou regressão linear simples para investigar a tendência de completitude das variáveis. Os percentuais de completitude foram considerados como variáveis dependentes (Y) e os anos da série, como independentes (X). Os resultados mostram um incremento significativo de 204% no número de notificações. Porém, das 34 variáveis analisadas, 27 (79,4%) apresentaram tendência Estacionária, 6 (17,6%) Decrescente e apenas uma (2,9%) Crescente. A completitude foi considerada ‘Muito Ruim’ para as variáveis: Escolaridade (47,3%), Complemento (21,3%), Hora da Ocorrência (38,0%) e Uso de Álcool Pelo Agressor (47,0%). Portanto, apesar do grande incremento no numero de notificações, a qualidade dos dados permaneceu comprometida, dificultando uma análise mais realista neste grupo.

Abstract The scope of this study was to analyze the trend of completeness of the data on violence perpetrated against adolescents registered in the State of Pernambuco between 2009 and 2012. This involved a cross-sectional survey of 5,259 adolescents, who were the victims of violence reported in SINAN-VIVA of the Pernambuco State Health Department. Simple linear regression was used to investigate the trend of completeness of the variables. The percentages of completeness were considered to be dependent variables (Y) and the number of years as independent variables (X). The results show a significant increase of 204% in the number of notifications. However, of the 34 variables analyzed, 27 (79.4%) showed a stationary trend, 6 (17.6%) a downward trend, and only one variable (2.9%) an upward trend. Completeness was considered ‘Very Poor’ for the variables: Education (47.3%), Full Address (21.3%), Occurrence Time (38%) and Use of Alcohol by the Attacker (47%). Therefore, despite the large increase in the number of notifications, data quality continued to be compromised, hampering a more realistic analysis of this group.

RESUMO Objetivo Avaliar a reprodutibilidade interdias, a concordância e a validade do construto da versão reduzida da Depression Anxiety Stress Scale-21 aplicada a adolescentes. Método A amostra foi composta por adolescentes de ambos os sexos, com idades entre 10 e 19 anos, recrutados de escolas e centros esportivos. A validade de construto foi realizada por análise fatorial exploratória, e a confiabilidade foi calculada para cada construto, por meio de coeficiente de correlação intraclasse, erro padrão de medida e mudança mínima detectável. Resultados A análise fatorial combinando os itens correspondentes a ansiedade e estresse em um único fator, e depressão em um segundo fator apresentou melhor adequação de todos os 21 itens, com cargas fatoriais mais altas em seus respectivos construtos. Os valores de reprodutibilidade para a depressão foram coeficiente de correlação intraclasse com 0,86, erros padrão de medida com 0,80 e mudança mínima detectável com 2,22 e, para a ansiedade/estresse, foram coeficiente de correlação intraclasse com 0,82, erro padrão de medida com 1,80 e mudança mínima detectável com 4,99. Conclusão A versão reduzida da Depression Anxiety Stress Scale-21 apresentou excelentes valores de confiabilidade e também uma forte consistência interna. O modelo de dois fatores com a condensação dos construtos ansiedade e estresse em um único fator foi o mais aceitável para a população adolescente.

ABSTRACT Objective To evaluate the interday reproducibility, agreement and validity of the construct of short version of the Depression Anxiety Stress Scale-21 applied to adolescents. Methods The sample consisted of adolescents of both sexes, aged between 10 and 19 years, who were recruited from schools and sports centers. The validity of the construct was performed by exploratory factor analysis, and reliability was calculated for each construct using the intraclass correlation coefficient, standard error of measurement and the minimum detectable change. Results The factor analysis combining the items corresponding to anxiety and stress in a single factor, and depression in a second factor, showed a better match of all 21 items, with higher factor loadings in their respective constructs. The reproducibility values for depression were intraclass correlation coefficient with 0.86, standard error of measurement with 0.80, and minimum detectable change with 2.22; and, for anxiety/stress: intraclass correlation coefficient with 0.82, standard error of measurement with 1.80, and minimum detectable change with 4.99. Conclusion The short version of the Depression Anxiety Stress Scale-21 showed excellent values of reliability, and strong internal consistency. The two-factor model with condensation of the constructs anxiety and stress in a single factor was the most acceptable for the adolescent population.

Conclusão O não uso de preservativos esteve associado com bebedeira nos últimos 30 dias nas meninas.

ABSTRACT Objective To determine the association between not using the male condom and alcohol consumption in adolescents and schoolchildren. Methods An epidemiological study, with a cross-sectional, descriptive, and correlation design carried out from March to July 2014. The sample consisted of students in public primary and secondary education, aged between 12 and 24 years. The social and demographic survey and the Youth Risk Behavior Survey questionnaire were used. Results The study included 1,275 students, of these; 37.0% reported having had sexual relations. The prevalent age of sexual initiation was 14-16 years 55.7% and 65.6% used condom in the last sexual intercourse. Regarding the lack of condom use at the last intercourse, girls showed an association with drunkenness in the previous 30 days (2.19; 95%CI: 1.06-4.54). Conclusion In females, the non-use of condoms was associated with drunkenness in the previous 30 days.

Resumo Objetivo: Investigar a presença de sintomas musculoesqueléticos em adolescentes estudantes do ensino médio em escolas públicas e sua associação com o uso de dispositivos eletrônicos. Método: A amostra foi composta por 961 meninos e meninas entre 14 e 19 anos que responderam questionário sobre o uso de computadores, jogos eletrônicos e questões relacionadas a sintomas dolorosos e atividade física. Além disso, todos os voluntários foram submetidos à avaliação antropométrica. Para análise inferencial foram usados os testes de qui-quadrado e modelo múltiplo de regressão logística. Resultados: A presença de sintomas de dor musculoesquelética foi reportada por 65,1% dos adolescentes, mais prevalente na coluna toracolombar (46,9%), seguida por dor nos membros superiores (20%). O tempo médio de uso de computador e jogos eletrônicos foi de 1.720 e 583 minutos por semana, respectivamente. O uso excessivo dos dispositivos eletrônicos mostrou-se como fator de risco para dor cervical e lombar. O sexo feminino apresentou associação com a presença de dor em diferentes partes do corpo. A atividade profissional esteve associada com a dor cervical. Conclusão: Observou-se alta prevalência de dor musculoesquelética nos adolescentes e elevado tempo de uso dos dispositivos eletrônicos. Entretanto, foi possível observar somente a associação do uso excessivo desses dispositivos e a presença de dor cervical e lombar.

Abstract Objective: This study investigated the presence of musculoskeletal symptoms in high school adolescents from public schools and its association with electronic device use. Methods: The sample consisted of 961 boys and girls aged 14–19 years who answered a questionnaire regarding the use of computers and electronic games, and questions about pain symptoms and physical activity. Furthermore, anthropometric assessments of all volunteers were performed. The chi-squared test and a multiple logistic regression model were used for the inferential analysis. Results: The presence of musculoskeletal pain symptoms was reported by 65.1% of the adolescents, being more prevalent in the thoracolumbar spine (46.9%), followed by pain in the upper limbs, representing 20% of complaints. The mean time of use for computers and electronic games was 1.720 and 583 minutes per week, respectively. The excessive use of electronic devices was demonstrated to be a risk factor for cervical and lumbar pain. Female gender was associated with the presence of pain in different body parts. Presence of a paid job was associated with cervical pain. Conclusion: A high prevalence of musculoskeletal pain in adolescents, as well as an increased amount of time using digital devices was observed. However, it was only possible to observe an association between the increased use of these devices and the presence of cervical and low back pain.

The aim of the present study was to investigate the perception of health care service managers about the network action for the care of adolescent victims of violence. A qualitative, exploratory, descriptive study conducted from May to July of 2013. The subjects were 15 managers of a hospital that is a referral center for cases of violence in the Brazilian State of Pernambuco. Data were collected through semi-structured interviews and explored using content analysis. The results indicate that social work plays an aggregating and interconnecting role as required by the network action.
