      Validation of the PAQ-C and IPAQ-A questionnaires in school children. (English)
    • Abstract:
      Physical activity questionnaires have been proposed as useful alternatives of objective measures (accelerometry or podometry). Nonetheless, there is a lack of consensus regarding which questionnaire better quantifies physical activity levels in Spanish children. The main aim of the present study was to determine the validity of the "Physical Activity Questionnaire for Children" (PAQ-C) and the "International Physical Activity Questionnaire for Adolescents" (IPAQ-A) questionnaires completed both by children and their parents. Twenty-four healthy children (9.1±0.6 years) wore an accelerometer seven consecutive days. The children and their parents completed the PAQ-C and IPAQ-A questionnaires. The PAQ-C was compared to the moderate and vigorous physical activity obtained by the accelerometer, while the IPAQ-A was compared according to intensities of physical activity (PA). Correlations obtained between the PAQ-C and accelerometry were positive for children (rho=0.42;p<.05), although the contingency tables showed differences between methods. For the IPAQ-A the correlations between accelerometry and data reported by the children were low (Pearson(r) -0.36 to 0.31), while those reported by the parents were slightly higher. Significant differences were found between the reported data registered by the questionnaires and accelerometry data. To summarize, the PAQ-C and IPAQ-A questionnaires have a questionable validity when quantifying PA in Spanish children. [ABSTRACT FROM AUTHOR]
    • Abstract:
      Los cuestionarios se han propuesto como una buena alternativa a los métodos objetivos (acelerometría o po-dometría), sin embargo, no parece existir un consenso sobre qué cuestionario es el mejor para cuantificar los niveles de actividad física en niños españoles. El objetivo del presente estudio fue el de validar los cuestionarios "Physical Activity Questionnaire for Children" (PAQ-C) y el "International Physical Activity Questionnaire for Adolescents" (IPAQ-A) completados por niños/as y sus padres. Para ello, 24 niños/as sanos (9.1±0.6 años) llevaron un acelerómetro siete días consecutivos, completando tanto ellos como sus padres el PAQ-C e IPAQ-A. La puntuación del PAQ-C se comparó con la actividad física (AF) moderada y vigorosa obtenida por el acelerómetro, mientras que en el IPAQ-A se compararon minutos por intensidades de AF con los del acelerómetro. Las correlaciones obtenidas entre el PAQ-C y acelerometría fueron positivas para niños/as (rho=0.42; p<.05), aunque las tablas de contingencia mostraron diferencias entre métodos. Para el IPAQ-A las correlaciones con lo reportado por niños/as fueron bajas (Pearson(r) -0.36 a 0.31), mientras que las de los padres fueron ligeramente superiores. Se observaron diferencias significativas entre lo reportado en los cuestionarios frente a lo registrado por los acelerómetros. A partir del presente estudio se puede concluir que los cuestionarios PAQ-C e IPAQ-A tienen una validez cuestionable para cuantificar la AF en niños/as españoles. [ABSTRACT FROM AUTHOR]
