Associations between sedentary time and EQ-5d index score in middle-aged and older adults

초록

Purpose: This study was conducted to identify the associations between sedentary time and EuroQol-5-dimensional (EQ-5D) index score in middle-aged and older adults. Materials and methods: Data were extracted from the 6th Korea National Health and Nutrition Examination Survey (2014-2015). Subjects aged ≥ 45 y were selected for analysis (n=3,543). Self-reported sedentary time and EQ-5D index score were the outcome variables. The sedentary time was dichotomized into ≥ 7.5 h/d and <7.5 h/d. To ensure that the sample represents the Korean population, sampling weights were generated by considering a complex sample. Associations with sedentary time and EQ-5D index score were analysed using multiple logistic regression. Results: Sitting for ≥ 7.5 h/d was significantly associated with 85% (odds ratio, 0.15; 95% confidence interval, 0.08-0.30) lower odds of EQ-5D index score when adjusted for sex and age compared to those who were sitting for <7.5 h/d. Conclusion: These findings imply that in order to improve health-related quality of life in middle-aged and older adults, sedentary time should be reduced. © 2018, Scientific Publishers of India.
