Evaluación de los cambios en la actividad física de los participantes de un programa implantado en una empresa\EVALUATION OF CHANGES IN PHYSICAL ACTIVITY AMONG PARTICIPANTS IN A COMPANY-BASED PROGRAM. (Spanish)

Objective: To analyze the effectiveness of a company-based physical activity program using the International Physical Activity Questionnaire (IPAQ) questionnaire. Methods: In March 2014 we implemented a company-based physical activity program (Mueve-T, by its Spanish acronym) with the objective of increasing awareness of physical activity among employees, and measuring improvements in activity level. To evaluate the effectiveness of the program, we administered the IPAQ Questionnaire, before the program began in 2014 and two years later, in 2016. Descriptive summary statistics included frequencies, percentages and bar charts. To compare pre- and post-intervention results, we used a logistic repeated measures model, adjusted for two populations, with an ordinal polytomous response for IPAQ (low or inactive, moderate and high), applied to the overall study population and further examined by sex, workplace and job. Results: A total of 746 participants responded in 2014 and 563 in 2016. Only 314 respondents completed both surveys. In 2014, 35.4% of the respondents reported a low level of activity, moderate was 39.5% and highwas, 25.2%. In 2016, 36.3% reported a low level of activity, moderate was 39.8% and a high level was indicated by 23.9%. Overall, there were no significant differences in physical activity levels between the pre- and post-intervention period, among those who participated in both surveys. Likewise, there were no significant differences when this result was examined by sex, although employees sales or commercial tasks has lower levels of physical activity as compared to other centers or jobs. Conclusions: The results did not find this intervention program to be effective in increasing levels of physical activity. The differences found among the sales and commercial task employees could have been due to differences in the effect on awareness achieved by com- panywide information dissemination (e.g., newsletters, talks, intranet notes, etc.) as compared to specific individual activities (e.g., (yoga classes, zumba, cycling, walks, etc.). A longer evaluation period is needed to confirm these findings. [ABSTRACT FROM AUTHOR]

Objetivos: Evaluar los cambios en la actividad fisica de los participantes de un programa de actividad fisica (Mueve-T) implantado en el medio laboral. Métodos: En marzo del 2014, se iniciaron las actividades del programa Mueve-T con los objetivos de sensibilizar a los trabajadores en la practica de la actividad fisica y conseguir una mejora en el nivel de actividad. Para evaluar su efectividad se utilizó el Cuestionario IPAQ (International Physical Activity Questionnaire) antes de iniciarse el programa (2014) y a los dos anos (2016). Se realiza la comparación entre anos ajustando un modelo logistico de medidas repetidas de dos poblaciones de trabajadores de distintos centros de trabajo de la misma empresa con respuesta ordinal politómica para IPAQ (nivel bajo o inactivo, moderado y alto), para toda la población y estratificado por sexo, centro de trabajo y puesto de trabajo. Resultados: Se incluyen los 314 trabajadores que respondieron el cuestionario en los dos anos. En 2014 un 35,35% de los encuestados reportaron un nivel bajo de actividad, un 39,50% moderado y un 25,15 un nivel alto. En 2016 un 36,30% reportaron nivel bajo de actividad, un 39,80% nivel moderado y un 23, 90% un nivel alto. El analisis de respuesta entre anos no ha mostrado evidencia de cambio entre anos (p=ns). No se han encontrado diferencias por sexo, pero si una menor actividad en determinados centros y puestos de trabajo. Conclusiones: Si valoramos los resultados del programa y su efectividad con el cuestionario IPAQ, observamos que estadisticamente no muestran cambio en actividad fisica estadisticamente significativo; pero si hay cambios en el nivel de actividad manteniéndose y au- mentando en un grupo de trabajadores, a su vez consideran el programa efectivo y desean continuar con las actividades. Para obtener un aumento del nivel de actividad fisica se precisaria de un periodo mas largo de evaluación. [ABSTRACT FROM AUTHOR]
