Kim and Lee: The relationship of quality of health-related life with the status of oral health in adults

Abstract

Objectives

The purpose of this study was to use the components of the European Quality of Life-5 dimension (EQ-5D) scale to investigate the oral health status and health-related quality of life of adults in order to collect basic data on how to improve quality of life.

Methods

This study was conducted in 2014. Data from the 6th Korean National Health and Nutrition Examination Survey (sixth term; 2 years) were analyzed by utilizing the raw information from the disease management headquarters. The 2,805 subjects were 19 to 59-year-old adults who were not missing values of the main missing value of oral health status in variables and the EQ-5D. Statistical analysis was performed by frequency analysis and chi-squared (χ2) and t-tests. Analysis of variance was performed using multiple regression analysis. The significance level was determined to be 0.05.

Results

Dental pain and mobility (P<0.005), pain and discomfort (P<0.005), chewing problems and speaking discomfort, anxiety and depression (P<0.05), subjective oral health awareness, mobility (P<0.001), self-care (P<0.05), usual activities (P<0.05), pain and discomfort (P<0.005) were significantly related. In the effect on the components of the EQ-5D by logistic regression analysis, gender, age, education level, household income, chewing problems, and periodontal disease prevalence were significant variables in the quality of health-related life.

Conclusions

The results showed that oral health status significantly influenced the quality of life in adults. Through the recognition of the impact of oral health on health-related quality of life, we expect that the data from this study will help promote the development of oral health and oral health education programs for the maintenance and promotion of adult health.
