Accelerometer-Measured Physical Activity and Sedentary Behavior in Individuals With and Without Chronic Diseases: Cross-Sectional Results of 27,890 Adults From the Swedish CArdioPulmonary BioImage Study Cohort.

BACKGROUND

This study compared levels of physical activity (PA) and sedentary behavior (SB) in adults with and without chronic diseases or multimorbidity, acknowledging sociodemographic factors.

METHODS

A cross-sectional analysis was conducted with data from 27,890 participants (52% women), aged 50-64, from the Swedish CArdioPulmonary bioImage Study cohort. Over 1500 chronic diseases were included and categorized into chronic disease and multimorbidity groups. Chronic diseases were retrieved from national registries, using International Classification of Disease codes. PA and SB were measured with a triaxial hip-worn accelerometer, over 7 consecutive days. General linear models were used to calculate estimated means for daily time spent in light-intensity PA (LIPA), moderate- to vigorous-intensity PA and SB.

RESULTS

Time spent in LIPA, moderate- to vigorous-intensity PA, and SB did not differ between individuals in a chronic disease group and individuals without chronic diseases. Individuals living with any multimorbidity spent less time in moderate- to vigorous-intensity PA than participants without chronic diseases. Individuals living with 4 or more chronic diseases spent more time sedentary than individuals without chronic diseases. Women spent more time in LIPA and less time in SB than men, regardless of chronic disease or multimorbidity. Individuals with less education spent more time in LIPA and less time in SB than individuals with more education, regardless of chronic disease or multimorbidity.

CONCLUSIONS

When using an extensive set of chronic diseases, marginal differences in PA and SB were seen between individuals living with and without chronic diseases. PA and SB seem to significantly differ by sex and education, rather than living with chronic disease.
