OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation and high symptom burden that interferes with physical activity and results in a vicious cycle of inactivity and symptom worsening. The aim of this multicenter, observational study was to determine the prevalence and severity of morning, daytime and night-time symptoms as well as patterns of physical activity levels (PALs) and their interrelation in Belgian COPD patients, enrolled in the multinational SPACE study (NCT03031769). METHODS: Socio-demographic, socio-economic and disease characteristics data were collected from patients' medical records as part of a routine visit to their primary care practice or pulmonologist. Dedicated questionnaires were used to evaluate respiratory symptoms for each part of the day. PAL was assessed by means of self- and interview-reported tools, and physician's judgment. Patients were also classified according to GOLD recommendations 2013 and 2017. RESULTS: Overall, 102 Belgian patients participated in the study (mean age 67 years, 60.8% males). Over 85% of patients experienced respiratory symptoms throughout the day and about one-third were considered as 'active' (PAL ≥150 minutes/week). Physician-assessed PALs were higher than self-reported PALs, categorizing fewer patients as 'inactive' (17.6% versus 42.2%, respectively). PALs and symptoms were weakly interrelated. Inactive patients were present in all GOLD classification groups. CONCLU...
