(February 20, 2014) – New data shows a strong link between sitting down and the presence of ADL disability.

A study by Dorothy Dunlop, PhD, Northwestern Medicine Health Services, evaluated 2,286 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 regressions.

These adults spent almost 9 hours per day being sedentary during waking hours. The study found that the odds of ADL disability were 46 percent greater for each daily hour spent in sedentary behavior, adjusted for moderate-vigorous activity, socioeconomic, and health factors.

These findings support programs encouraging older adults to decrease sedentary behavior regardless of their engagement in moderate or vigorous activity.
