El sedentarismo perjudica gravemente la salud

Cuadro de Vittore Carpaccio, fundación Thyssen, Madrid

En la vida todo acaba matando, incluso el no hacer nada. Todos sabemos que los extremos son malos. Estar picando 12 horas al día en una mina no tiene buena pinta. Pasarse la vida tirado en un sillón tampoco.

Nuestro cuerpo tiene un diseño dirigido a la actividad física. Estamos hechos para caminar y correr, no para anclarnos a una silla.

El mayor problema lo tienen las personas de más edad. Un reciente estudio aporta evidencias de que el sedentarismo es factor de riesgo para la discapacidad y la dependencia. 


De alguna forma esto ya lo sabemos todos. El reto vuelve a ser el mismo: atrevernos a movernos más.

• Si va al supermercado, aparque en un lugar alejado a la entrada

• Cuando se levante a por agua, camine por la casa o la oficina

• Si puede, suba las escaleras a pie en lugar de elegir el ascensor

• Haga los pequeños recados caminando y no coja el coche

• Levantese cuando hable por teléfono o en las reuniones en la oficina
• Planifique actividades de ocio compartido al aire libre: paseos, excursiones...
• Cree rutinas para salir a pasear
• Si se cita para conversar con alguien hágalo caminando

ABSTRACT
Background: The harmful relationship of sedentary behavior to health may reflect an exchange of sedentary activity for moderate-vigorous activity or sedentary behavior may be a separate risk factor.   We examined whether time spent in sedentary behavior is related to disability in activities of daily living (ADL), independent of time spent in moderate-vigorous activity in older adults. Methods:  The nationally representative 2003-2005 National Health and Nutrition Examinations Surveys (NHANES) included 2286 adults aged 60 years and older with accelerometer-assessed physical activity. The association between ADL task disability and the daily percentage of sedentary time was evaluated by multiple logistic regression. Results:  This sample spent almost 9 hours/day being sedentary during waking hours and 3.6% reported ADL disability. The odds of ADL disability were 46% greater (odds ratio 1.46, 95% confidence interval: 1.07, 1.98) for each daily hour spent in sedentary behavior, adjusted for moderate-vigorous activity, socioeconomic, and health factors. Conclusion: These U.S. national data show a strong relationship between greater time spent in sedentary behavior and the presence of ADL disability, independent of time spent in moderate or vigorous activity. These findings support programs encouraging older adults to decrease sedentary behavior regardless of their engagement in moderate or vigorous activity.
