Item Acesso aberto (Open Access) Características do ambiente escolar associadas à prática de educação física e ao deslocamento ativo em adolescentes de Belém-PA: um estudo multinível(Universidade Federal do Pará, 2025-02-26) SOUZA, Naicha Stefanie Félix; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; https://orcid.org/0000-0003-4683-9576Understanding 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.Item Acesso aberto (Open Access) Desigualdade e interseccionalidade em domínios da atividade física e tempo de tela entre adolescentes de Belém(Universidade Federal do Pará, 2024-12-27) SILVA, Lucas Fernando Alves E; CRISP, Alex Harley; http://lattes.cnpq.br/1187580727139009; https://orcid.org/0000-0003-4683-9576Inequities influence various aspects of health, including physical activity and sedentary behaviors among adolescents. In Belém, these disparities may be exacerbated by the socioeconomic and demographic conditions characteristic of the Amazon region. This study investigated inequalities across different domains of physical activity and screen time among adolescents in Belém (PA), considering the wealth index, sex, and school administrative dependency, while also exploring the intersectionality of vulnerabilities across multiple dimensions. Data from 1,719 adolescents (49% girls, 58% from public schools) were analyzed. Prevalence rates were calculated for school-based physical education (≥1 day/week and ≥30 minutes), active transport (≥5 days/week), leisure-time physical activity (≥60 minutes/day), and excessive screen time (≥4 hours/day). Inequalities were assessed using the Slope Index of Inequality (SII) and absolute differences, with 95% confidence intervals obtained via bootstrap. Determinants included the wealth index (quintiles), sex, school administrative dependency, and the Jeopardy Index for multiple risk factors. Adolescents in the fourth quintile of the wealth index had higher prevalence rates for leisure-time activities (32.9%) and participation in physical education classes (39.9%), while active transport was more frequent among those in the first quintile (58.7%). Excessive screen time was more prevalent among girls (57.0%) and private school students (72.3%), whereas boys (46.5%) and public-school students (54.4%) had higher prevalence rates for active transport. Analysis using the Jeopardy Index revealed greater inequality in excessive screen time (66.2%) among girls attending private schools with higher socioeconomic levels, while boys in the same group showed higher prevalence of leisure-time activities (44.4%). Conversely, students with greater vulnerability according to the Jeopardy Index demonstrated a higher prevalence of active transport (57.0%). The greatest magnitude of inequality was observed for active transport (SII = 0.398; 95% CI: 0.324 to 0.466) and screen time (SII = -0.328; 95% CI: -0.405 to -0.258). Leisure-time activities (SII = -0.180; 95% CI: - 0.244 to -0.110) and physical education (SII = -0.104; 95% CI: -0.182 to -0.026) also exhibited significant inequalities, albeit with lower magnitudes, disproportionately affecting more vulnerable adolescents. In conclusion, physical activities and screen time are influenced by various layers of inequality, with boys of higher socioeconomic status being more active in leisure-time activities and girls more exposed to excessive screen time. Among the most vulnerable groups, higher rates of active transport were observed, potentially reflecting a need rather than a choice.
