Sedentary behavior and associated factors on admissions to internal medicine wards

The relationship between sedentary lifestyle and chronic diseases is well known. This study examined the prevalence and factors associated with reduced physical activity (PA) among internal medicine inpatients on admission. In this single-center, cross-sectional study, inpatients aged 50 years or older were prospectively enrolled at a tertiary care facility in Ankara, Türkiye. PA was assessed using the International Physical Activity Questionnaire (IPAQ). Care and performance indicators, quality of life (EQ-5D 3L), nutritional status, timed up-and-go test, muscle strength, and cognitive status were assessed. Participants were classified into 3 groups of PA levels as low, moderate, and high. Study end points were the prevalence of low PA level and associated factors. Of the 240 participants (mean age: 62.7 ± 8.0 years; women: 50%), 47.1% (n = 113), 40.8% (n = 98) and 12.1% (n = 29) had low, moderate, and high PA, respectively. Type 2 diabetes mellitus (45.1%), hypertension (66.4%), coronary artery disease (41.6%), dementia (8.8%), and multimorbidity (53.1%) were more common in the low PA group. Outdoor walking < 3 days per week (OR: 4.44, 95% CI 1.55 to 12.74, p = 0.006, functional dependence in and outside home (OR: 4.25, 95% CI 1.13 to 15.92, p = 0.032) and EQ-5D VAS score (OR: 0.97, 95% CI 0.95 to 0.99, p = 0.011) were independently associated with low PA level on multivariable logistic regression analysis. This study found low or medium levels of PA in almost nine out of ten admissions to an internal medicine clinic. On the other hand, low PA level was not associated with most classical comorbidities but with altered performance and care indicators.
