The questionnaire showed high internal consistency and moderate reliability. Furthermore, a model with two factors seems to be the most appropriate to evaluate the quality of sleep in adolescents.

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.

HighlightsThe occurrence of shoulder pain in young people is high and is associated with older adolescents.Handball and judo increase the prevalence of shoulder pain, when compared with other sports.Adolescents with shoulder pain had lower joint function and mobility.

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 O objetivo deste artigo é verificar a associação entre autopercepção negativa em saúde e violência escolar em adolescentes estudantes do Município de Olinda - PE. Estudo transversal, analítico e de base escolar com amostra constituída por 2.614 adolescentes, selecionados por meio de uma estratégia de amostragem aleatória em conglomerados. As informações foram obtidas através do questionário “Youth Risk Behavior Survey” de onde foram retiradas as questões de violência bem como da autopercepção de saúde. Os dados foram tabulados pelo programa Epi-data versão 3.1 e transcrito para o SPSS versão 22. Utilizou-se os teste do Qui-quadrado e o modelo de regressão logística binária stepwise para análise dos dados. Observou-se que 26,7% dos adolescentes tinham uma autopercepção negativa em saúde, sendo maior entre as moças. Em relação à violência escolar, a autopercepção negativa esteve associada ao sentimento de tristeza, pensamento suicida, bullying na escola, roubado na escola e segurança na escola. Sexo e idade também se mantiveram associadas (p < 0.05). Reforça-se a necessidade de ações de cultura e paz na adolescência, envolvendo o ambiente escolar, a fim de refletir na analise de saúde pobre dos adolescentes reduzindo também o índice de violência.
