The relevance of subjective health recognition and happiness index of local community residents (Using community health survey data 2014) / 대한구강보건학회지

OBJECTIVES: Health is closely related to an individual's assessment of their quality of life and their subjective level of happiness. The aim of this study was to investigate the association between happiness index and self-rated health by utilizing a community health survey in Korea. METHODS: The study participants were 17,937 people living in Gyeongsangnam-do, Korea, who completed a community health survey in 2014. The non-subjective variables included in the statistical analysis were sex, age, region, education, income, and economic activity. The subjective awareness variables included self-rated health, self-rated oral health, chewing difficulty, pronunciation difficulty, and happiness index. Statistical analysis of the data was done using the SPSS 21.0 program. RESULTS: Evaluation of the subjective awareness levels revealed that the respondents that were better educated, whose income levels were higher, and those who engaged in an economic activity found themselves to be in better physical health and oral health. In contrast, the respondents that were female, older, and with residence in the counties reported a higher incidence of chewing difficulty. There was a positive correlation between happiness index and subjective awareness level, and a negative correlation between chewing difficulty and pronunciation difficulty. Happiness index was influenced the most by subjective health levels, followed by income, age, pronunciation difficulty, subjective oral health, chewing difficulty, academic credential, region, and sex. CONCLUSIONS: Therefore, in order to improve the happiness index of community residents, regular health checkups and systematic oral health education should be prepared in order to improve awareness of subjective health and reduce discomfort in the oral cavity, and efforts should be made to reduce the gap between regions.

Correlation between depressive symptoms and subjective mastication ability and ability to pronunciation among Korean elderly / 한국역학회지

OBJECTIVES: The present study examines the relationship between depressive symptoms and subjective chewing and pronunciation ability in Korean seniors. Our goal is to provide the data required to develop appropriate oral health interventions programs for seniors. METHODS: The Center for Epidemiologic Studies-Depression Scale (CES-D) is widely used depressive symptoms assessment. A Korean version was used for the 2009 Community Health Survey, which was consulted to extract the present study's subjects, comprising 50,694 Korean seniors (males, 20,582; females, 30,112) aged ≥65 years. Those with a CES-D score ≥16 were rated 'depressed.' SAS version 9.3 was used for the data analysis. RESULTS: Prevalence of depressive symptoms increased as the subjects' socioeconomic status decreased, number of health issues increased, health behavior worsened, and chewing and pronunciation discomfort increased. Males with chewing difficulties were found to have 1.45 times (95% confidence interval [CI], 1.29 to 1.63) greater risk of depressive symptoms than those without, while males with pronunciation discomfort were found to have 1.97 times greater risk of depressive symptoms than those without (95% CI, 1.76 to 2.20). Females with chewing difficulty were found to have 1.50 times (95% CI, 1.39 to 1.61) greater risk of depressive symptoms than those without, and females with pronunciation discomfort were found to have 1.55 times greater risk of depressive symptoms than those without (95% CI, 1.44 to 1.67). CONCLUSIONS: Intervention programs designed to help with oral health management and alleviate depressive symptoms in seniors are urgently needed. As the prevalence of depressive symptoms may vary geographically, research examining potential variance at city, district, and town levels would be beneficial.

Socio-economic inequalities in tooth loss and chewing difficulty in the Korean elderly / 대한구강보건학회지

OBJECTIVES: This study aimed to assess socio-economic inequalities in subjects with 20 or more natural teeth and chewing difficulty in the Korean elderly, and to assess the association of health behavior factors, psychological factors, and oral health status on social gradients of subjects with tooth loss and chewing difficulty. METHODS: Cross-sectional data were from the Fourth Korea National Health & Nutrition Examination Survey. Subjects were 3,598 people over the age of 65 years, who participated in a health interview, dental examination and dietary survey. Income status and educational status were selected as measures of socio-economic position (SEP). Logistic regression models were used to assess socio-economic inequalities of subjects with 20 or more natural teeth and chewing difficulty. To assess the association of related factors, a logistic model that was adjusted for each group of variables was compared to those that were not adjusted for it. RESULTS: We found that there were socio-economic differences in subjects with 20 or more natural teeth and chewing difficulty in Korean elderly. The social gradient for subjects with 20 or more natural teeth and chewing difficulty persisted, after adjusting for different factors. While adjusting for oral hygiene factors and smoking factors attenuated the association between 20 or more natural teeth and SEP, adjusting for oral health status and psychological factors attenuated the association between chewing difficulty and SEP. Education status was a more apparent measure than income status, in socio-economic inequalities in oral health among the Korean elderly. CONCLUSIONS: Socio-economic inequalities in oral health among the Korean elderly might be important social problems. More extensive longitudinal research to confirm the pathways that explain oral health inequalities among the elderly is required, to develop effective intervention strategies to reduce socio-economic differences in oral health among the Korean elderly.
