Patients hospitalized due to an exacerbation of chronic obstructive pulmonary disease (ECOPD) often exhibit increased sedentary behavior (SB), which may persist after discharge and negatively affect recovery. However, early determinants of SB during this period remain unclear. To identify the factors at hospital discharge that predict SB 30 days later in patients with ECOPD. This observational longitudinal study included patients hospitalized for ECOPD, assessed during the first week after discharge and reassessed 30 days later. Data collected included sociodemographic information (age, sex, name, telephone number, and address), anthropometric measurements (weight, height, and body mass index [BMI]), clinical history (previous hospitalizations, exacerbations, and smoking status), dyspnea (Medical Research Council scale, mMRC), health status (COPD Assessment Test, CAT), co-morbidities (Charlson Comorbidity Index), and exercise capacity (6-minute walk test, 6MWT). Physical activity and sedentary behavior-including SB, light (LPA), moderate (MPA), and vigorous (VPA) physical activity, step count, and sleep-were measured using a triaxial accelerometer worn for seven consecutive days. Accelerometer data were processed with ActiPASS software, and statistical analyses were performed in RStudio. Stepwise regression analysis was used to identify the discharge variables that could predict SB at 30 days. Forty-four patients (61% female; age 66 ± 8 years; FEV Show less

The aim of this study was to explore the prospective association between compositions of accelerometry-measured occupational physical behaviors and the risk of knee pain among eldercare workers. We performed a prospective study among 377 eldercare workers employed across 20 Danish nursing homes. Occupational physical behaviors were measured using thigh-worn accelerometers over 1-4 working days. Workers reported intensity of and days with knee pain in a questionnaire at baseline and after one year. We explored associations between compositions of occupational physical behaviors [ie, sedentary, standing, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA)] and knee pain, adjusting for potential confounders. No significant associations were found. Trends were found for increased occupational time spent in MVPA and decreased risk of days with knee pain [relative risk (RR) 0.58, 95% confidence interval (CI) 0.32-1.05, P=0.07] in main analyses, and for decreased risk of knee pain intensity among non-knee pain cases (RR 0.36, 95% CI 0.12-1.13, P=0.08) in sensitivity analyses. No significant associations were found between baseline occupational physical behaviors and knee pain at one-year follow-up. However, a non-significant trend suggested that increasing occupational MVPA might be associated with reduced risk of knee pain at follow-up, though studies with larger samples are needed to confirm this finding.
