OBJECTIVE: To investigate the association between physical inactivity and anthropometric
measures in schoolchildren from Paranavaí-Parana, Brazil. METHODS: Cross-sectional survey, carried out in July and August 2013. Sample of 566
students (287 boys and 279 girls) from 6th to 9th grade, aged 10 to 14 years, from
public and private schools of Paranavaí - PR, Southern Brazil. The variables
analyzed were: time of weekly physical activity through a questionnaire (physical
inactivity <300 minutes/week), body mass index (BMI) and waist circumference
(WC). In the statistical analysis, the U Mann-Whitney and Student's
t tests were used for comparison between genders. To identify
factors associated with insufficient levels of physical activity, univariate and
multivariate logistic regression analysis was applied and expressed in Odds ratio
(OR) and 95% confidence interval (95%CI). RESULTS: There was an association between physical inactivity and anthropometric
measurements for BMI (p<0.001) and WC
(p<0.001), with a prevalence rate of 56.1% and 52.7% of
inactive adolescents, respectively. In the multivariate analysis, there was
significant association of physical inactivity and overweight (OR 1.8, 95%CI:
1.1-3.0) and with increased waist circumference (OR 2.8, 95%CI: 1.4-3.8). CONCLUSIONS: Inadequate levels of physical activity is a determining factor for overweight and
abdominal adiposity. Accordingly, preventive measures should be taken, especially
in schools, emphasizing the importance of exercise for body composition control
and weight reduction.
El objetivo fue analizar las experiencias vivenciadas por los estudiantes que ingresaron a cursos de Licenciatura en Educación Física en el Estado de Paraná (Brasil) con la gimnasia de competición durante la Educación Primaria y Secundaria. La investigación se caracterizó como descriptiva con abordaje cualitativo y cuantitativo. Participaron 168 estudiantes que ingresaron en el año 2017 en cursos de Licenciatura en Educación Física de cuatro universidades públicas de Paraná. Fue utilizado un cuestionario con información sociodemográfica, preguntas abiertas y cerradas sobre la experiencia del contenido de gimnasia de competición en el contexto escolar. Para analizar las preguntas abiertas fue utilizado el análisis de contenido. En el análisis de información sociodemográfica y preguntas cerradas se usó estadística descriptiva. Se evidenció escasa experiencia por parte de los estudiantes con las modalidades de gimnasia de competición y falta de oportunidad de estos alumnos de vivenciar y reflexionar sobre la gimnasia en la Educación Física escolar.
