Objectives: The aim of the study was to investigate the association of self-perceived oral health and depression in the Korean elderly. Methods: The subjects were 1,329 elderly in Korea from the sixth Korea National Health and Nutrition Examination Survey (the 6th KNHANES). The dependent variable was depression that continued more than two weeks. Model I for the impacts of depression on self-reported oral health, Model II for the impacts of depression on chewing problem, Model III for the impacts of depression on speaking problem was evaluated. PASW Statistics 18.0 version was used for frequency analysis, chi-square test and logistic regression analysis. Results: Female elderly were much more prone to depression than male. Female had lower monthly compensation, less medicaid, chewing problem, speaking problem, and less education. For these reasons, they tended to have more depression than male (p<0.001). Self-perceived oral health impacts on depression included poor self-reported oral health(p<0.01), poor chewing problem(p<0.01) and poor speaking problem(p<0.05). On the other hand, male did not show a statistically significant association. Conclusions: The study showed the self-perceived oral health related quality of life had a significant influence on depression in the elderly. The continuing lifelong oral health care can prevent depression in the later life because oral health care improvement can enhance the self-perceived oral health status.
Objectives: This study aimed to investigate the effect of the oral health status on risk factors for obstructive sleep apnea (OSA) using data from the 2019 National Health and Nutrition Examination Survey. Methods: Of a total of 2,422 persons, 1,295 and 1,127 were categorized into the control group (CG) and OSA risk group (OSARG), respectively. The effect of the oral health status on OSA risk factors was presented in Model 1 by performing a complex sample linear regression analysis. Results: Our findings showed that OSA risk factors decreased by 0.075 points when there were no speaking problems with demographic characteristics adjusted. In addition, when systemic diseases were adjusted for, OSA risk factors decreased to 0.074 points (p<0.05). Conclusions: Therefore, in order to reduce oral problems that affect OSA risk factors, dentists and dental hygienists should seek accurate recognition of OSA and effective oral care methods.
Objectives: The purpose of the study was to identify the relationship between metabolic syndrome and oral diseases in the middle aged and elderly in Korea. Methods: The study subjects were 6,390 people over 40 years old from 2010 and 2012 Korea National Health and Nutrition Examination Survey. The survey questionnaire consisted of health, nutrition, and oral examination surveys. The independent variables included general characteristics, health behavior, oral health behavior, and metabolic syndrome. The dependent variables included dental caries experience and periodontal disease. The oral examination was carried out by the dentist based on World Health Organization standard. Results: The average prevalence rate of metabolic syndrome MS was 23.79%, including 54.84% of risk group and 21.37% of normal group. The missing teeth rate was 82.38%, DMFT rate was 90.28% and the periodontal disease rate was 33.15%. Those having abnormal fasting blood glucose had 1.17 fold(95% CI: 1.00~1.37) higher periodontal disease than the normal group. The abnormal HDL cholesterol group had 1.25 times higher odds ratio(95% CI: 1.07~1.46) and the obese group had 1.27 times higher odds ratio(95% CI: 1.07~1.51). The risk group had 1.20 times higher odds ration(95% CI: 1.00~1.44) and that of the metabolic syndrome group was 1.60 times higher(95% CI: 1.29~1.97) in periodontal disease. The high blood pressure group had 1.25 times of missing teeth prevalence rate(95% CI: 1.00~1.37). The metabolic syndrome group had 1.47 times of missing teeth prevalence rate(95% CI: 1.11~1.94). Conclusions: The middle aged and elderly people in Korea had higher rate of metabolic syndrome and oral disease. It is necessary to implement the preventive oral health examination for the control of metabolic syndrome and oral diseases prevalence.
Objectives: The purpose of this study was to investigate the influence of demographic characteristics and oral health status on unmet dental needs among preschool children and to provide a basis for improvement of the dental care equality and accessibility using data from the $6^{th}$ National Health and Nutrition Survey. Methods: This study was performed using data collected from the $6^{th}$ National Health and Nutrition Survey. The subjects were 1,472 out of 22,940 people, who participated in the survey and under went oral examination. IBM SPSS Statistics (Version 20.0) was used for statistical analyses based on the complex sampling design. Frequency analysis was performed to determine the distribution of unmet dental needs according to the characteristics of the subjects. The Rao-Scott ${\chi}^2$ test was performed to examine the relationship of unmet dental needs with general characteristics and health- and oral health-related variables. Relevant factors were determined using binary logistic regression analysis. Results: The factors that had statistically significant relations with unmet dental needs included age, medical insurance, household income, limited physical activity, history of dental caries in deciduous teeth, and subjective health status. Logistic regression analysis of complex samples was conducted to determine factors related to unmet dental needs. The results of analysis showed that limited physical activity and history of dental caries in deciduous teeth were related to unmet dental needs. Conclusions: The results show the factors affecting, and the reasons for, the unmet dental needs of preschool children. Future studies are needed to develop national projects and oral health education reforms to address inequalities in preschool children's dental care.
Background: Parental attention is crucial for preventing childhood oral diseases. Mothers play a significant role in maintaining their families' oral health, and their educational level influences their children's oral health behaviors. This study investigates the impact of mothers' educational levels on adult oral health behaviors using data from a national survey. Methods: This study employed a cross-sectional analysis of secondary data. The data used were obtained from the 8th Korea National Health and Nutrition Examination Survey. Descriptive statistics were calculated to identify participant characteristics. Next, t-tests and one-way analysis of variance were conducted to examine the effects of the explanatory variables on the distribution of the dependent variable. Finally, logistic regression analysis was used to investigate the influence of the explanatory variable on the dependent variable, using "no education" as the reference value, and calculate the odds ratios. Results: Children of mothers with a college education or higher had a 1.13 times higher likelihood of receiving oral examinations than those whose mothers had no education. Children whose mothers graduated from college or higher had a 2.23 times higher probability of receiving preventative dental treatment than those whose mothers had no education. Children whose mothers graduated from college or higher had a 1.92 times higher probability of receiving scaling than those whose mothers had no education. Children whose mothers graduated from high school had a 1.35 times higher probability of receiving scaling than those whose mothers had no education. Conclusion: Developing oral health programs is important for low-educated and low-income parents to change theirs and their children's oral health behaviors/attitudes. This will help reduce oral health disparities among adults raised by parents of higher and lower socioeconomic statuses. Therefore, a comprehensive approach is essential for adults to maintain good oral health, regardless of variations in their parental educational levels during childhood.
Objectives: The aim of this study was to evaluate the relationship between depressive symptoms and oral health status in Korean middle-aged women. Methods: We analyzed data from the sixth Korea National Health and Nutrition Examination Survey (KNHANES VI). The final sample consisted of 2,691 adults aged 40-64 years. The Chi-squared test was used to assess the rate of depressive symptoms, oral health status, and relationship between oral health status and depressive symptoms. Moreover, logistic regression analysis was used to examine the association between depressive symptoms and oral health status. Data were analyzed using SPSS 20.0 program. Results: Overall, 15.1% of subjects experienced depressive symptoms. The rate of depressive symptoms in self-aware oral health, toothache, and mastication problem groups were 19.6%, 19.9%, and 25.3%, respectively. Compared to other groups, the likelihood (odds ratio) of having depressive symptoms was 1.47 (95% confidence interval [CI] : 1.16-1.88), 1.58 (95% CI: 1.22-2.04), and 1.73 (95% CI: 1.32-2.28) higher in self-aware bad oral health, toothache, and mastication problem groups, respectively. Conclusions: We found an association between depressive symptoms and oral health status. Thus, oral health status should be evaluated as a potential risk factor for depressive symptoms.
Objectives: The purpose of this study was to investigate the oral health status and oral health behavior and identify the factors related to the oral health status by age-specific groups in vulnerable elderly individuals. Methods: We used data from the 7th Korea National Health and Nutrition Examination Survey. The differences in the oral health status and oral health behavior by age-specific groups were analyzed using complex sample chi-square tests and a generalized linear model. The relationship between the oral health status and oral health behavior by age-specific groups was analyzed using a complex samples general linear model. Results: The DMFT index of the young-old elderly was 10.65±0.60, and that of the old-old elderly was 12.78±0.72, which was higher. The condition of the mandibular prosthesis was more common in the old-old elderly, and there was a statistically significant difference (p<0.05). The DMFT index in the old-old elderly was found to be higher as the average number of brushings per day decreased, and no oral examination was performed. Conclusions: The vulnerable elderly themselves are interested in maintaining their own health, and the government needs to undertake efforts to reduce the medical blind spots by supporting institutional and environmental conditions so that health care services can be provided to the vulnerable elderly.
Background: With increased interest in oral health, several efforts have been made to improve oral health conditions. To achieve this, needs for oral health must be precisely determined and accurately measured. Therefore, factors influencing both objective unmet dental needs, which were determined by experts, and perceived unmet dental needs, which were determined by patients, were examined in this study. Methods: Responses of 17,735 respondents aged greater than 19 years from the Korean National Health and Nutrition Survey collected using the fifth (2010~2012) rotation sample survey were analyzed. Based on the information collected from the survey and dental examination, we determined the associations between the independent (sex and socioeconomic level) and dependent variables using a chi-squared test. Moreover, ordinal logistic regression analyses on multiple categorical values were performed using perceived and objective dental needs as the dependent variables. Results: Generally, factors influencing both perceived and objective dental needs were similar. These included sex, household income, educational level, private insurance, and subjective oral health status. However, the high-income groups had lesser perceived and objective dental needs compared to the low-income groups. Furthermore, factors such as sex, educational level, and marital status had different influence on both needs. Conclusion: Generally, factors that affect perceived and objective dental needs were similar. To minimize unmet dental needs, factors influencing both perceived and objective dental needs should be examined for a broad dental insurance coverage, and efforts to prevent oral diseases are also required.
Objectives: In this study, raw data from the 7th (2016-2018) of the Korea National Health and Nutrition Examination Survey were used, and a total of 2,430 people were selected as participants to analyze the factors related to unmet dental care needs in postmenopausal women. Methods: Frequency analysis, cross analysis, and logistic regression analysis were performed for general characteristics, oral health characteristics, and unmet dental care needs related factors using IBM SPSS Statistics 21.0 program. Results: The unmet dental care related factors were 1.527 times higher in the case of not having oral examinations than in the case of having oral examinations. For those who did not make use of the dental clinic, 8.667 times, 2.913 times for bad oral health, and 1.912 times for usually showed that unmet dental care was higher. Inconvenience with speaking was 1.578 times higher, and in the absence of implants, unmet dental care needs was 1.510 times higher. In the case of no chewing difficulty, was 0.380 times lower. Conclusions: Based on the above results, in order to achieve the policy goal to reduce unmet dental care needs, policy support and interest are needed above all to accurately identify and solve specific problems.
Objectives: The objective of the study was to review the correlation between self-perceived oral health status and periodontal diseases in elderly Koreans, using data from the $6^{th}$ (2nd year) Korea National Health and Nutrition Examination Survey (2014). Methods: The subjects for this study were a total of 1,454 elderly people aged 65 years or older who responded to the health questionnaires of the $6^{th}$ (2nd year) Korea National Health and Nutrition Examination Survey conducted in 2014. Their general characteristics were analyzed using frequency analysis, while a cross-tabulation analysis (${\chi}^2-test$) was performed to understand the correlation with periodontal diseases. To clarify any effect of self-perceived oral health status on periodontal diseases, the selected variables were controlled and subsequently analyzed according to the logistic regression analysis. Results: In terms of the difference between elderly people with periodontal disease and those without periodontal disease, higher prevalence rates of periodontal diseases were found in women, those of younger age, those with lower educational and income levels, those with poorer subjective oral health status, those in the presence of chewing discomfort, those who had a toothbrushing frequency of twice per day, and/or those who had received no oral examination over the previous one year. Regarding the effect of self-perceived oral health status on periodontal diseases, 1.78-fold and 1.74-fold higher prevalence rates of periodontal diseases were shown with poorer subjective oral health status and in the presence of chewing discomfort, respectively. Conclusions: Based upon the results above, it is considered that a better understanding of self-perceived oral health status is necessary for a healthy life of the elderly. Furthermore, constant relevant studies and effective prevention programs intended to moderate the progress of or prevent periodontal diseases in the elderly in communities should be performed and implemented for the sake of better quality of life and oral health.
