Abstract

This cross-sectional study aimed to investigate the association between sociodemographic factors and levels of health-related physical fitness and in school children. The sample consisted of 1000 children and adolescents aged 7 to 17 years, from Santa Cruz do Sul-RS. Socioeconomic status was evaluated by the criteria of the Brazilian Association of Research Companies (ABEP) and the nutritional status through the body mass index (BMI). The flexibility, abdominal strength and cardiorespiratory fitness (CRF) were evaluated following the protocols of Sport Brazil Project (PROESP-BR). All analyzes were performed using SPSS v. 23.0 considering a significance level of p<0.05. The results showed that low levels of flexibility are more prevalent among boys (PR: 1.16; p<0.001) and school children of urban area (PR: 1,06; p=0.045). The prevalence of low levels of abdominal strength are also associated with male sex (PR: 1,12; p<0.001), as well as the municipal (PR: 1.13; p=0.011) and state (RP: 1,19; p <0.001) education. The prevalence of overweight/obesity is higher in males (RP: 1,05; p=0.025) and lower among adolescents (PR: 0.89; p<0.001). On the other hand, male students have a 6% lower prevalence of low levels of CRF (p=0.001). Adolescents (RP: 1,07; p=0.005), students of the municipal system (PR: 1,10; p=0.049) and from urban area (PR: 1,09; p=0.002) have a higher prevalence of low levels of CRF. It was concluded that sociodemographic factors are associated with low levels of health-related physical fitness in school.
