Abstract
Background: Currently, obesity is a major public health concern. The proportion of elderly in South Korea has increased gradually, and the prevalence of obesity among the elderly has also increased. Obese elderly are more prone to illnesses, which can negatively affect their quality of life. However, there have not been many studies about the relationship between weight and health-related quality of life (HRQoL) among elderly Korean women. This research aimed to identify how weight influences quality of life of women over 65 years of age in Korea by analyzing the relationship between weight and HRQoL.
Methods: This study used data from the 2010–2011 Korean National Health and Nutrition Examination Survey. EuroQol five dimensions questionnaire (EQ-5D) index scores were classified as satisfactory or unsatisfactory based on the median value. Univariate and multivariate logistic regression analyses were then used to assess the influence of weight on HRQoL with consideration for socioeconomic and pathologic variables in subjects.
Results: In the analysis, valid body weight measurements and EQ-5D index scores from 1,607 female subjects aged 65 years or older were selected. Higher body weight did not appear to be associated with lower HRQoL according to the univariate logistic regression. In addition, weight had little influence on HRQoL according to the multivariate logistic regression with adjustments for covariates.
Conclusion: There is no meaningful association between weight and HRQoL in elderly Korean women.
