METHODS
Participants
A total of 230 community dwelling adults (≥45 years old) who were admitted to the physical and rehabilitation medicine outpatient clinic of a tertiary care university hospital were recruited. Subjects who had neuromuscular or rheumatic diseases, history of major orthopedic surgery and mobility limitations were excluded from the study. All participants were informed about the study procedure and subjects were enrolled if they consented to participate. The local ethics committee approved the study protocol.
Demographic data, smoking status, comorbidities (e.g. hypertension, diabetes mellitus, chronic cardiovascular/pulmonary disease) and drug usage were noted. Weight, height and waist/hip circumferences were measured to the nearest 0.1 kg and 1 cm.
