LAUSR

The study is investigated socioeconomic variations in perceived oral health status and contribution of oral health behavioral factors. A nationally representative sample (365 health and 1,787 unhealth aged 20 over years) from the 2015 Korea National Health and Nutrition Surveys was analyzed using logistic regression. Perceived oral health was lower among lower socioeconomic groups compared with higher socioeconomic groups. This association was increased when demo-socioeconomic factors and oral health behavioral were adjusted. When each oral health behavioral factor was considered separately, mediators such as smoking, frequency of tooth brushing and used oral care products or oral health examination explained a large part of the increased socioeconomic oral health status. Subjective bad oral health arise from different socioeconomic status, but this difference is increased by oral health behavioral factors. Therefore, socioeconomic inequity in perceived oral health status can be corrected more effectively by promotional oral health behaviors.
