    The application of the health belief model in oral health-related dietary behavior

    Ja-Young Na , Hyo-Won Oh , Heung-Soo Lee

    Abstract : Objectives: This study aimed to investigate the relationship between oral health beliefs and oral health-related dietary behavior.Methods: The participants of this cross-sectional study were 728 middle school students living in Jeonju who were selected through convenience sampling. For the survey, self-administered questionnaires were completed in individual settings. The analysis model was the oral health belief model, and the analysis method was path analysis.Results: Among oral health beliefs, perceived susceptibility, perceived severity, perceived barriers, and self-efficacy were found to be correlated with the oral health-related dietary behavior index. Multiple regression analysis showed that factors affecting the oral health-related dietary behavior index were gender (female), perceived susceptibility, perceived severity, perceived barriers, and self-efficacy. Path analysis showed that variables that significantly impact the oral health-related dietary behavior index are perceived susceptibility, perceived benefits, perceived barriers, and likelihood of action. The factor with the greatest impact was perceived barrier; the lower the barrier, the higher the level of dietary behavior undertaken to prevent dental caries.Conclusions: Oral health beliefs are related to oral health-related dietary behavior. Since perceived barriers had the greatest correlation with oral health-related dietary behavior, measures must be taken to help remove the barriers.

    You-Jin Cho , Min-Ji Byon , Eun-Joo Jun et al.

    Abstract : Objectives: This study compares the labeling information on the sizes of interdental brushes marketed in Korea to their actual sizes. Moreover, it analyzes the relationship between the size of the passage hole diameter (PHD), brush diameter, stem diameter, and stem length.Methods: Among the commercially available interdental brushes in Korea, 171 interdental brushes, 3 in each size, were collected from 9 companies. The labels of the collected interdental brushes were researched, and the PHD was measured and compared. The correlation between the passage hole diameter, brush diameter, stem diameter, and stem length was analyzed. Multiple regression analysis was performed to verify the effect of brush diameter, stem diameter, and stem length on the determination of the PHD.Results: The sizes of the interdental brushes were expressed using the ISO labeling or the Small, Medium, Large (S, M, L) labeling and indicated in units of 0.1. The concordance rate of the measured PHD and named PHD was 39.7%. The measured brush diameter, stem diameter, and stem length increased as the interdental brush size increased. There was a significant correlation (P

    Effect of oral health-related self efficacy and social support on oral health-related quality of life among adolescents

    Boo Young Choi , Heung-Soo Lee , Hyo-Won Oh

    Abstract : Objectives: This study aimed to examine the effects of oral health-related self efficacy and social support on oral health-related quality of life, and analyze the related factors.Methods: A cross-sectional study was carried out on 979 high school students living in Iksan. Data were collected from January 15 to 30, 2014. Individual self-administered surveys were conducted through the sampling method. The contents of the survey were the characteristics of the subjects, oral health-related self efficacy (OHSE), social support related to oral health (OHSS), and quality of life related to oral health (QHRQoL). A survey tool designed by the author was used to measure OHSE and OHSS. QHRQoL used Child Oral Health Impact Profile-Short Form 19 (COHIP-SF 19) for examination. The statistical analysis methods used were mean difference, correlation, and multiple regression analyses.Results: QHRQol was correlated with OHSE, but not OHSS. Per the multivariate analysis, factors that affected QHRQoL were gender, mother’s education level, academic stress, and OHSE; OHSS did not have any effect.Conclusions: It was found that OHSE influenced QHRQoL. Therefore, it is necessary to develop education programs that can enhance OHSE.
