Sim Seon-Ju

Abstract
Objective: The purpose of this study was to examine association between oral health bahaviors and health related quality of life (HRQoL).

Methods: The study used data from Korea National Health and Nutrition Examination Survey (KNHANES V: 2010-2012 & VI KNHANES VI: 2013?2015). A dependent variable, HRQoL, was decided as EuroQol-5 dimension (EQ-5D). Oral health behaviors were defined as the frequency of toothbrushing, the presence of interdental cleaning, and the presence of regular dental check-up and socioeconomic variables and health-related were collected. HRQoL was analyzed by social class, health behaviors, and oral health behaviors. Multiple logistic regression analysis was used to evaluate the association between oral health behaviors and EQ-5D.

Results: The subjects with low social class, hypertension, diabetes mellitus had any problem with EQ-5D (p<0.001). The group with less tooth brushing frequency had problem with low HRQoL and high odds ratios (ORs) for low HRQoL (ORs [95% confidence Interval, CI]; mobility 1.56 [1.39-1.79], self-care 1.47 [1.15-1.89], usual activity 1.35 [1.16-1.56], pain/discomfort 1.10 [1.02-1.19], and anxiety/depression 1.19 [1.06-1.32]). The group without interdental cleaning had problem with low HRQoL and high ORs for low HRQoL (ORs [95% Cl]; mobility 1.52 [1.33-1.72], usual activity 1.18 [1.01-1.39], and anxiety/depression 1.14 [1.02-1.27]. The group without regular dental check-up had problem with low HRQoL and high ORs for low HRQoL (ORs [95% CI]; mobility 1.23 [1.09-1.41] and anxiety/depression 1.14 [1.02-1.28]).

Conclusion: HRQoL was associated with oral health behaviors. Therefore, it is necessary that oral health promotion programs had better be planned with health promotion program to improve HRQoL.
