Abstract
OBJECTIVE: To determine the test-retest reliability and validity of the Spanish version of the short-form International Physical Activity Questionnaire (IPAQ) among adults in Mexico. METHODS: This was a cross-sectional study of a convenience sample of 267 adult factory workers in Mexico City. Participants were 19 - 68 years of age; 48% were female. Participants wore an accelerometer for 9 consecutive days and were administered the Spanish version of the short form IPAQ on two occasions (IPAQ1 and IPAQ2, separated by 9 days). The relation and differences between moderate-to-vigorous physical activity (MVPA) measures obtained from IPAQ1, IPAQ2, and the accelerometer were determined using correlations, linear regression, and paired t-tests. RESULTS: IPAQ1 and IPAQ2 measures of MVPA were significantly correlated to each other (r = 0.55, P 0.01). However, MVPA was 44 ± 408 minutes/week lower in IPAQ1 than in IPAQ2, although this difference did not reach statistical significance (P = 0.08). The (min/week) measures from IPAQ1 and IPAQ2 were only modestly correlated with the accelerometer measures (r = 0.26 and r = 0.31, P 0.01), and by comparison to accelerometer measures, MVPA values were higher when based on IPAQ1 (174 ± 357 min/week, P 0.01) than for IPAQ2 (135 ± 360 min/week, P 0.01). The percentage of participants who were classified as physically inactive according to the World Health Organization guidelines was 18.0% in IPAQ1, 25.1% in IPAQ2, and 28.2% based on the accelerometer. CONCLUSIONS: Similar to what has been observed in other populations, the short form IPAQ has a modest reliability and poor validity for assessing MVPA among Mexican adults.(AU)
 
OBJETIVO: Determinar la fiabilidad en aplicaciones repetidas (test-retest) y la validez de la versión abreviada en español del Cuestionario Internacional de Actividad Física (CIAF) en adultos de México. MÉTODOS: Se llevó a cabo un estudio transversal de una muestra de conveniencia de 267 adultos que trabajaban en una fábrica de la ciudad de México. Los participantes tenían de 19 a 68 años de edad; 48% eran mujeres. Los participantes llevaron un acelerómetro durante nueve días consecutivos y se les administró la versión abreviada en español del CIAF en dos ocasiones (CIAF1 y CIAF2, con un intervalo de nueve días). Se determinó la relación y las diferencias entre las mediciones de la actividad física de moderada a vigorosa (AFMV) obtenidas mediante el CIAF1, el CIAF2 y el acelerómetro usando análisis de correlación y regresión lineal, y pruebas de la t para datos emparejados. RESULTADOS: Las mediciones de la AFMV mediante el CIAF1 y el CIAF2 se correlacionaron significativamente entre sí (r = 0,55, P 0,01). Sin embargo, en el CIAF1 se obtuvo una AFMV inferior a la del CIAF2 en 44 ± 408 minutos/semana, aunque esta diferencia no alcanzó significación estadística (P = 0,08). Las mediciones en minutos/semana del CIAF1 y el CIAF2 solo se correlacionaron moderadamente con las mediciones del acelerómetro (r = 0,26 y r = 0,31, P 0,01) y, en comparación con las mediciones del acelerómetro, los valores de la AFMV fueron mayores cuando se basaron en el CIAF1 (174 ± 357min/semana, P 0,01) que en el CIAF2 (135 ± 360 min/semana, P 0.01). El porcentaje de participantes que se clasificaron como físicamente inactivos según las directrices de la Organización Mundial de la Salud fue de 18,0% mediante el CIAF1, de 25,1% mediante el CIAF2 y de 28,2% mediante el acelerómetro. CONCLUSIONES: De manera análoga a lo observado en otras poblaciones, la versión abreviada del CIAF presenta una fiabilidad moderada y una validez deficiente para evaluar la AFMV en adultos mexicanos.(AU)
