Desenvolvimento e validação de um questionário de avaliação da atividade física para adolescentes

Abstract

OBJECTIVE:To develop a physical activity questionnaire aimed at Brazilian adolescents and to assess its validity and reproducibility. METHODS:A total of 94 adolescents (30 males and 64 females) aged 11-16 years were included in the study, which was conducted in 2004. The questionnaire comprised 17 questions on habitual physical activity in the last 12 months (15 questions on sports and physical exercise and two on transportation physical activity), and was standardized to yield final scores for weekly and yearly activity. As a reference, we used the multistage 20-meter shuttle run test, measuring variables maximum time in minutes, maximum speed, maximum oxygen uptake and maximum heart rate. For validity analysis, we used the Spearman coefficient and age-adjusted correlation. For reproducibility analysis, we repeated evaluations after 15 days and measured the intraclass correlation coefficient. RESULTS:For the weekly score, the highest correlations were obtained for maximum time for the entire sample (r=0.19), maximum speed for males (r=0.20), and both maximum oxygen uptake and maximum time for females (r=0.17). For the yearly score, the highest correlations were obtained for maximum time for the entire sample (r=0.30), maximum heart rate for males (r=0.22), and maximum time for females (r=0.23). In reproducibility analyses, correlations were 0.61 for weekly score and 0.68 for yearly score. CONCLUSIONS:The questionnaire was valid and reproducible. Its use is recommended for the evaluation of physical activity in epidemiological studies with adolescents.

Physical activity of female students in secondary schools in the context of physical activity recommendations fulfilment

“…It turns out that walking is highest represented criterion in both the aspect of physical activity recommendations fulfilment and the structure of physical activity presented in MET/minutes/week. As observed in another research [34], walkers have also a tendency to practice more vigorous and moderate intensity activities. It corresponds with our results, where the group of 18-yearold females, who reached the highest percentage rate of physical recommendation fulfilment, undertook the most volume of moderate and vigorous physical activity.…”

“…The results of the presented studies indicate that actions for promoting various forms of physical activity among adolescents should be continued and intensified [34].…”

Fatores associados à baixa duração do sono em adolescentes

“…The level of physical activity was investigated through the questionnaire proposed by Florindo et al26 This questionnaire consists of 17 questions on habitual physical activity, considering the total time in minutes and weekly, and was validated considering the cardiorespiratory fitness. The adolescents were classified as insufficiently active if they performed less than 300 min of weekly physical activity 27…”

“…O nível de atividade física foi investigado por meio do questionário proposto por Florindo et al26 É composto por 17 questões sobre atividades físicas habituais, considerado o tempo total em minutos e semanal, e foi validado com base na capacidade cardiorrespiratória. Os adolescentes foram classificados como insuficientemente ativos se fizessem menos de 300 minutos de atividades físicas semanais 27…”

Validade e reprodutibilidade de um questionário para medida de atividade física em adolescentes: uma adaptação do Self-Administered Physical Activity Checklist

“…Há poucos estudos publicados sobre a validade de questionários de atividade física testados em adolescentes brasileiros. Os que foram desenvolvidos focaram adolescentes das regiões Sul [14][15][16] e Sudeste do país 17 , mas raramente da região Nordeste 16 . Um determinado questionário pode apresentar níveis satisfatórios de reprodutibilidade e validade em uma determinada população, mas necessariamente não terá o mesmo desempenho quando aplicado em sujeitos que apresentam características distintas daquelas apresentadas pela população de referência 6 .…”
