A high prevalence of musculoskeletal pain/syndromes was observed in female adolescents. Musculoskeletal pain was mostly reported at a median age of 15 years, and students used at least two electronic devices. Reduced use of electronic games was associated with musculoskeletal pain syndromes.

Objective To evaluate physical and mental health indicators in adolescents with preexisting chronic immunocompromised conditions during coronavirus disease 2019 (COVID-19) quarantine. Methods A cross-sectional study included 355 adolescents with chronic conditions and 111 healthy adolescents. An online self-rated survey was used to investigate socio-demographic features, healthcare routine, and the quarantine impact on physical and mental health. The validated self-reported version of the Strengths and Difficulties Questionnaire (SDQ) was also applied. Results The median of age [14 (10-18) vs. 15 (10-18) years, p = 0.733] and frequencies of female (61% vs. 60%, p = 0.970) were similar between adolescents with preexisting chronic conditions and healthy adolescents during quarantine of COVID-19 pandemic. The frequencies of abnormal total difficulties score of SDQ were similar in patients and controls (30% vs. 31%, p = 0.775). Logistic regression analysis showed that being female (OR = 1.965; 95% CI = 1.091-3.541, p = 0.024), fear of underlying disease activity/complication (OR = 1.009; 95%CI = 1.001-1.018, p = 0.030) were associated with severe psychosocial dysfunction in adolescents with chronic conditions, whereas school homework (OR = 0.449; 95% CI = 0.206-0.981, p = 0.045) and physical activity (OR = 0.990; 95% CI = 0.981-0.999, p = 0.030) were protective factors. Further analysis of patients with chronic immunocompromised conditions and previous diagnosis of mental disorders (9%) compared with patients without diagnosis showed higher median of total difficulties score (p = 0.001), emotional (p = 0.005), conduct (p = 0.007), peer problems (p = 0.001) and hyperactivity (p = 0.034) in the former group. Conclusion Adolescents with preexisting chronic immunocompromised conditions during COVID-19 quarantine were not at higher risk of adverse health indicators. Being female, fear of underlying disease activity/complication, and household members working outside of the home were relevant issues for adolescents with preexisting chronic conditions. This study reinforces the need to establish mental health strategies for teens with chronic conditions, particularly during the pandemic.

Lourenço B, Queiroz LB. Crescimento e desenvolvimento puberal na adolescência. Rev Med (São Paulo). 2010 abr.-jun.;89(2):70-5. RESUMO:A puberdade é um período da adolescência que se caracteriza pelas mudanças biológicas que ocorrem nessa fase da vida. Com duração de cerca de dois a quatro anos, ela é marcada por crescimento esquelético linear; alteração da forma e composição corporal; desenvolvimento de órgãos e sistemas e desenvolvimento de gônadas e caracteres sexuais secundários. Este artigo se propõe a discorrer sobre esses eventos que compõem a puberdade, bem como os fatores que podem influenciá-los. . Constitui-se por um período relativamente curto, de cerca de dois a quatro anos de duração, no qual ocorrem todas as modificações físicas desse momento de transição da infância para a idade adulta. Essas transformações somáticas que ocorrem na adolescência têm caráter universal, ou seja, representam um fenômeno comum a todos os indivíduos nessa fase da vida. Embora ainda persistam dúvidas sobre a complexa dinâmica da ativação puberal, sabe-se que esse momento se inicia apos a reativação de neurônios hipotalâmicos, que secretam, de uma maneira pulsátil bastante específica, o hormônio liberador de gonadotrofinas (GnRH). A secreção desse resulta na consequente liberação também pulsátil dos hormônios luteinizante (LH) e folículo-estimulante (FSH) pela glândula hipó-fise. Isso ocorre inicialmente durante o sono e, mais tarde, estabelece-se em ciclo circadiano 2 . O crescimento e o desenvolvimento são DESCRitORES
