Association Between Self-Reported Sedentary Behavior and Health-Related Quality of Life Among Multimorbidity Patients in Singapore.
2021
Background The study examined the association between sedentary behavior and self-rated health-related quality of life (HRQoL) in a sample of patients with multimorbidity in Singapore recruited from a primary care clinic. Methods Sedentary behavior and physical activity were assessed with the International Physical Activity Questionnaire short form (IPAQ-SF). HRQoL was assessed with EuroQol-5 Dimension (EQ-5D) utility index, visual analogue scale (EQ-VAS) and its 5 subscales (Mobility, Self-care, Usual Activities, Pain/Discomfort, and Anxiety/Depression). Depression was assessed via Patient Health Questionnaire (PHQ-9). Logistic and linear regression analyses adjusting for the effect of physical activity, depression, and sociodemographic variables (i.e., age, gender, ethnicity, education) were conducted. Results 932 patients participated in the study (mean age:64.5±8.5 years, range: 35-80) and 55% were men. Results indicated that women were less likely to have sedentary behavior (≥7 hrs/day) than men. Results indicated sedentary behavior was associated with lower EQ-5D index scores, but not EQ-VAS scores. Participants who were sedentary for ≥7 hrs/day were more likely to endorse having problems with mobility, self-care, and usual activities, but not with pain/discomfort, nor anxiety/depression. Conclusion Sedentary behavior was associated with poorer HRQoL. There is a need for interventions and health promotions to reduce sedentary behavior in patients with multimorbidity.
