Under repeated surveys, missing values often appear for various reasons and are replaced by new samples. It is investigated that the existing estimator in repeated survey by Jessen (1942), which has been originally developed for the new samples of fixed size, can be used in such situation where the size of new samples is random. It is shown that the proposed estimator has smaller variance than the sample mean.

Objectives: The purpose of this study was to examine the association between periodontitis and health behavior in women aged ≥40 years. In addition, related factors were compared according to the presence or absence of cardiovascular disease. Methods: Data from the 7th Korean National Health and Nutrition Examination Survey (2016-2018) were used. The study included 3,801 women aged 40-79 years, who participated in a questionnaire health survey related to hypertension, stroke, myocardial infarction, and angina pectoris, as well as completed blood tests, anthropometry, and oral examination. Statistical analyses were performed using complex sample general linear, complex sample crosstabs, and complex sample logistic regression analyses. Results: In all subjects, smoking and drinking, use of interdental care products, and dental checkups were confirmed to be significantly related to periodontitis. In the group with cardiovascular disease, the use of interdental care products, experience in dental checkups, and toothbrushing more than three times a day were confirmed as significant factors for lowering the prevalence of periodontitis. In the group without cardiovascular disease, smoking and drinking, use of interdental care products, and experience in dental checkups were confirmed as the significant factors. Conclusions: To improve the periodontal health of women over 40 years of age with cardiovascular disease, a health education program including self-care methods for proper dental plaque management and regular dental checkups are critical. Additionally, awareness of the risks of smoking and drinking would be helpful even for women without cardiovascular diseases.

Objectives: The purpose of this study was to examine the effects of oral and mental health status on temporomandibular joint disorders (TMDs) and the effects of TMD symptoms on quality of life using data from the 5th 2012 National Health and Nutrition Examination Survey. Methods: A total of 1,154 people were selected as subjects for the study. Temporomandibular joint (TMJ) sounds (672 persons), TMJ pain (227 persons), and TMJ dislocation (255 persons) were the factors studied. The complex sample chi-square test was performed to compare demographic characteristics according to the three groups of TMD symptoms. Complex sample logistic regression analysis was performed to confirm the effect of oral and mental health status on TMDs, and complex sample linear regression analysis was performed to check the effect of TMDs on the quality of life (EQ-5D). Results: After adjusting for demographic characteristics, those without TMJ sound symptoms had lower pain/discomfort (OR: 0.055, CI: -0.095 to -0.016) and anxiety/depression (OR: 0.053, CI: -0.092 to -0.014). Those without TMJ pain had lower pain/discomfort (OR: 0.119, CI: -0.192 to -0.046) and anxiety/depression (OR: 0.071, CI: -0.137 to -0.004). Pain/discomfort (OR: 0.063, CI: -0.125 to -0.001) was lower in those without TMJ dislocation symptoms. After adjusting for mental health status, pain/discomfort (OR: 0.088, CI: -0.161 to -0.014) was found to be lower in those without TMJ pain symptoms (p<0.05). Conclusions: Based on the results of this study, the treatment of TMDs, oral health, and also mental health, is needed to improve the quality of life.

Purpose: This study aimed to compare the differences in the prevalence of metabolic syndrome between menopausal women and women of childbearing age and to determine the risk of metabolic syndrome among women in each group depending on whether they eat alone. Methods: Data of 1,813 women from the seventh Korea National Health and Nutrition Examination Survey (2016) were used. The collected data were analyzed using SPSS 20.0, and complex sample frequency analysis, descriptive statistics, complex sample cross analysis, complex sample general linear regression, and complex sample logistic regression analysis were performed. Results: According to the results of the study, there was no difference in the prevalence and risk of metabolic syndrome according to the presence of companions during meals between women of childbearing age and post-menopausal women, but there was a difference in health behavior. In other words, women of childbearing age who ate alone had a lot of experience of drinking, and menopausal women who ate alone did not tend to make any efforts to control their weight and did not perform aerobic exercise. In particular, the negative health behavior of menopausal women who ate alone increased the risk of prevalence of metabolic syndrome. Conclusion: The findings indicate that, for women who eat alone, interventions to prevent metabolic syndrome should be differentiated before and after menopause. Therefore, it is suggested to offer an educational program to prevent metabolic syndrome in women of childbearing age as well as provide regular assessments to diagnose metabolic syndrome and health behavior improvement programs for menopausal women.

Purpose: The purpose of this study was to investigate the relationship between systemic diseases and denture wear status in elderly. The subjects of this study were 4,340 seniors aged 65 or older who conducted screenings and health surveys using the National Health and Nutrition Survey data during the sixth period (2013, 2014 and 2015). Methods: For the general characteristics and denture wear status according to general systemic diseases, complex sample frequency analysis and cross-analysis were performed. After controlling the general characteristics, complex sample logistic regression analysis was performed to determine the relationship between systemic diseases and denture wear status. Statistical software was used for SPSS (SPSS 23.0 for Windows, SPSS Inc, USA). Significance level was considered as 0.05. Results: A multisample logistic regression analysis was performed to determine the relationship between systemic diseases and denture wear status. The results showed that the dentured state had a significant effect on dyslipidemia and diabetes. Conclusion: Dyslipidemia and diabetes, which are related to denture wearing condition, need to be prevented and treated with regular checkups. In addition, based on the results of the study, it is thought that the elderly need denture prosthetic treatment after tooth extraction. In addition, it can be used as basic data for oral health business plan that can maintain and manage oral health.

Purpose: This study investigated the association between adolescent health behaviors (drinking, smoking, and drug use) and sexual intercourse, as well as the moderating effects of economic status, cohabitation with parents, and school type, among adolescents in Korea. Methods: Secondary data from the 16th Adolescent Health Behavior Survey (2020) were used. A total of 395 schools and 54,948 middle and high school students participated in the study. Complex sample frequency analysis, the Rao-Scott test, and complex sample logistic regression analyses were performed. Results: Sexual intercourse rates for men and women were 5.8% and 3.3%, respectively. Approximately 7.3% of high school students and 1.8% of middle school students reported having had sexual relations. Drinking (odds ratio [OR] = 3.15, 95% confidence interval [CI] = 2.82~3.52), smoking (OR = 6.75, 95% CI = 5.90~7.71), and drug use (OR = 3.03, 95% CI = 2.23~4.11) significantly increased the risk of sexual intercourse. Economic status and school type had moderating effects on the association between drinking and sexual intercourse. Conclusion: Adolescent drinking, smoking, and drug use are associated with a higher risk of sexual experience. Thus, to reduce this risk, controlling alcohol consumption, smoking, and drug use is necessary. In addition, programs for healthy lifestyles and sexual intercourse should be differentiated according to the school type and the economic conditions of the adolescents' households.

The purpose of this study was to identify chronic diseases and oral health care behaviors in 65-year-old individuals and to determine the factors that influence masticatory mobility. The raw data from the 8th National Health and Nutrition Examination Survey in 2020 were utilized to analyze factors associated with chewing discomfort in 1,278 elderly Koreans. Using IBM SPSS Statistics 27.0, we conducted complex sample cross-analysis to examine the difference in chewing discomfort based on general characteristics, chronic diseases, and oral health care behaviors. Additionally, we performed complex sample multiple logistic regression analysis to identify the factors associated with chewing discomfort. As a factor influencing chewing discomfort, unmet dental care was 3.33 times higher (p<0.001), and subjective oral health was 0.18 times more likely to be moderate (p<0.001) and 0.48 times more likely to be good (p<0.001) lower. In the case of arthritis, the level of chewing discomfort was high (OR=1.08, p=0.694), but there was no significant difference. As a result of the aforementioned factors, it is believed that there is a need for policies and systems to provide dental care to the elderly before their oral health deteriorates. Additionally, tailored oral health promotion programs should be implemented.

Objectives: To investigate factors related to scaling between Korean and multicultural families using data from the 18th Youth Health Behavior Survey (KYRBS), 38,320 Korean adolescents were selected as subjects. Methods: A complex sample cross-analysis was conducted on general characteristics and oral health characteristics using the IBM SPSS program. Factors related to adolescent scaling were analyzed using complex sample logistic regression analysis. Results: Compared to Korean families, adolescents from multicultural families had 0.50 times less scaling experience within 12 months. Learning achievement was 1.30 times higher in high compared to low, indicating that scaling experience was high. In terms of economic status, scaling experience was found to be high at 1.50 times in high compared to low. Non-smoking adolescents had 1.26 times higher scaling experience. It was found that adolescents who do not use dental floss and interdental brushes have 0.71 and 0.55 times less scaling experience, respectively. Conclusions: Based on the above results, there is a need to increase adolescents awareness of oral health and motivate them to manage their own oral care. There is a need to provide opportunities to participate in various oral health education programs and to deepen continuous oral health education on oral disease prevention.
