Understanding how school environment characteristics influence adolescent physical activity behaviors is essential for developing targeted interventions. The aim of this study was to investigate the associations between school environment characteristics and the levels of participation in Physical Education (PE) classes and active commuting to school. This is a cross sectional study with multistage sampling, involving 1,719 adolescents from 46 public and private high schools in the municipality of Belém, Pará. The time spent in PE classes and active commuting during the previous week was self-reported based on the National School Health Survey questionnaire. School environment characteristics were obtained through questionnaires completed by school administrators and researcher observation visits. Zero-inflated negative binomial regression models were used to address overdispersion and excess zeros in the data. The results indicated that the majority of students (55.0%) did not participate in practical PE classes, with only 37.6% reporting 30 minutes or more of activity per week. Regarding active commuting, approximately one-third of adolescents (34.6%) did not engage in this type of commuting. In the logit component of the adjusted models, factors associated with reduced odds of non-participation in PE classes included a higher number of PE teachers (OR = 0.79; 95% CI: 0.71–0.87), the presence of locker rooms (OR = 0.66; 95% CI: 0.54–0.83), and school accessibility (OR = 0.68; 95% CI: 0.54–0.86). For active commuting, the presence of sidewalks (OR = 1.34; 95% CI: 1.03–1.74) and bike racks (OR = 1.61; 95% CI: 1.26–2.05) increased the odds of non-engagement, while speed bumps (OR = 0.60; 95% CI: 0.43–0.82) reduced the odds of non-engagement. In conclusion, school environment characteristics have the potential to decrease non-adherence to practical PE classes among adolescents. However, active commuting behaviors may depend on factors beyond infrastructure, requiring further exploration.

A dança jazz como estratégia de cuidado ao adolescente com Diabetes Mellitus Tipo 1: um relato de caso
(Universidade Federal do Pará, 2024-02-26) DOURADO, Julyanna Nazareth da Silva; BENTO-TORRES, Natáli Valim Oliver; http://lattes.cnpq.br/1927198788019996; https://orcid.org/0000-0003-0978-211X
Diabetes Mellitus (DM) is a metabolic disorder associated with persistent hyperglycemia due to inadequate insulin production or reduced effectiveness of its mechanism of action. Type 1 Diabetes Mellitus (DM1), previously called “insulin-dependent diabetes” or “juvenile-onset diabetes,” accounts for 5 to 10% of DM cases. The DM1 complications can affect the living conditions of adolescents over the years and influence their quality of life. Physical exercise is a therapeutic tool for the treatment of people with DM1 and can improve insulin sensitivity and glycemic control, improving quality of life, mental health, and physical fitness. Dance is a low-explored option of physical exercise in the context of DM. In the present study, we report a single case study to investigate the potential of Jazz Dance as an intervention to achieve glycemic management, promote mental health, improve the physical fitness and quality of life of a 12-year-old female teenager with DM1, improve physical fitness and quality of life in an adolescent with DM1. The intervention program encompasses 24 Jazz classes twice a week, lasting 60 minutes, at moderate intensity (65 to 75% of maximum heart rate, Polar@). Pre- and post-intervention assessments (1 day after the choreographic presentation) include usual physical activity practice (Physical Activity Questionnaire for Adolescents PAQ-A), quality of life (Diabetes Quality of Life for Youths - DQOLY), symptoms of anxiety and depression (Depression, Anxiety and Stress Scale - Short Form - DASS-21), physical fitness (muscle strength of lower and upper limbs and indirect measure of cardiorespiratory fitness), and glycemic control (glycemia and glycated hemoglobin). Discursive textual analysis was also applied to assess the adolescent and her caregiver experiences (CAAE: 66423922.2.0000.0017/Approval number: 5.913.924). The results demonstrated a reduction in Fasting Glycemia (-16.02%), HbA1c (-4.00%), pre-test (-24.21%) and post-test (-9.56%) heart rate, depressive and anxious symptoms (-7.14%), and improved quality of life (3.61%). There was an increase in muscular strength in the upper limbs (20.00%), flight time, strength, and power in the lower limbs (0.27%; 1.62%; 1.70%, respectively). Despite limited evidence on the effect of dancing on people with DM, the data presented indicate the beneficial potential of Jazz in the care of adolescents with DM1, just as the report of the experience lived by the adolescent points to the positive impact of the intervention on her self-care routine and perceived quality of life. Despite the limitations of extrapolating our results to the teenage population with DM1, it is necessary to expand the research to include a more significant number of participants, as well as expand research on dance modalities as part of the treatment of DM1, aiming to quantify and qualify more precisely the potential adaptations and modifications provided to these people through dance.

Redes sociais via estrutura social cognitiva em adolescentes de uma turma do ensino médio
(Universidade Federal do Pará, 2021-06-17) GODINHO, Rejane Célia de Souza; PONTES, Fernando Augusto Ramos; http://lattes.cnpq.br/1225408485576678
Cognitive social structure maps social relationships perceived by the actors. This study characterizes network pattern of a high school classroom and verifies relationship perception and accuracy in this environment. To this end, two interconnected studies were carried out: 1) A review based on cognitive social structure analysis that aimed to investigate and systematize literature regarding the design of Cognitive Social Structure in social network analysis in a school environment to identify gaps, contributions, limitations, and improvement of this technique. 2) Descriptive and exploratory study to characterize differential positioning of adolescents in the social network topology, according to cognitive social structure, in terms of network patterns (greater or lesser density). The results of the first study indicate strategies that measure individual accuracy and group perceptions of the relationships established in each social network. Based on these data, study two characterized the differential positioning of adolescents in the social network topology and found that the subjects with greater precision in identifying real relationships are subjects who perceive the group less densely, and with clear separations between subgroups. Our results differ from little literature in the area regarding greater precision in subjects with less centrality of degree and intermediation.
