Resumo: | More objective methods to detect inactive adolescents may help identify young people that are vulnerable to obesity and other chronic diseases. The objective of this study was to examine the association between classifications obtained with the cardiorespiratory fitness test and physical activity level in adolescents, as well as the agreement between tertiles and z-score distribution of the variables generated with these methods (distance covered and total physical activity score). A cross-sectional study was conducted using a random sample of 639 adolescents (61% girls) aged 12 to 19 years (mean age of 16 ± 1.8 and categorized into two age groups: 12-13 and 14-19 years), from public schools in Niterói, Rio de Janeiro, Brazil. Cardiorespiratory fitness was assessed by a 9-min run/walk test (T9) and physical activity level by the International Physical Activity Questionnaire (IPAQ). The chi-square test (or Fisher’s exact test) and Kruskal-Wallis test were applied for the evaluation of associations, and the weighted kappa coefficient and intraclass correlation coefficient were used to investigate agreement between variables. A level of significance of p<0.05 was adopted. A significant association between the classifications obtained with the two methods was only observed for adolescents aged ≥ 14 years. However, there was agreement between the variables generated with the two methods in both age groups. The median distance covered in the T9 increased according to tertiles of total physical activity score. An association between the classifications obtained with the IPAQ and T9 was only found for older adolescents. However, the continuous variables and variables categorized into tertiles generated with the methods were associated and showed agreement in both age groups. |

O objetivo do estudo foi examinar a associação entre as classificações obtidas pelo teste de aptidão cardiorrespiratória e o nível de atividade física, bem como a concordância entre os tercis e a distribuição em z escore das variáveis geradas a partir destes métodos (metros percorridos e escore total de atividade física), em adolescentes. Estudo transversal com amostra probabilística composta por 639 adolescentes (61% meninas), entre 12 e 19 anos (idade média de 16 anos ± 1,8 e categorizados em duas faixas etárias: 12 a 14 e 15 a 19 anos), de escolas públicas de Niterói-RJ. A aptidão cardiorrespiratória foi estimada pelo teste de corrida e caminhada de 9 minutos -T9 e o nível de atividade física pelo International Physical Activity Questionnaire -IPAQ. Para avaliação de associações, foram utilizados os testes Qui quadrado (ou teste de Fisher) e Kruskal Wallis e para concordância o coeficiente Kappa ponderado (Kp) e coeficiente de correlação intraclasse (CCI). Adotou-se p<0,05 para significância estatística. Observou-se associação significativa entre as classificações obtidas pelos dois métodos apenas para os adolescentes com idade igual ou maior que 14 anos, mas houve concordância entre as variáveis geradas a partir dos mesmos para as duas faixas etárias. As medianas de metros percorridos em T9 aumentaram de acordo com os tercis de escore total de atividade física. A associação entre as classificações obtidas com base nos métodos IPAQ e T9 foram observadas apenas para os adolescentes com mais idade. Todavia, as variáveis contínuas e categorizadas em tercis, geradas a partir dos métodos, associaram-se e apresentaram concordância para ambas as faixas etárias.Universidade Federal de Santa Catarina.
