Purpose: The purpose of this study was to examine the association between the intake of semi-solid yogurt and periodontitis in Korean adults using a national database. Methods: The data analyzed in this study are a subset of the sixth Korean National Health and Nutrition Examination Survey conducted in 2015 by the Korea Centers for Disease Control and Prevention. The sample size for this study was 4,727. We collected data on sociodemographic characteristics, oral health-related variables, oral and general health status, and intake of semi-solid yogurt. Semi-solid yogurt intake (YI) was calculated by multiplying the frequency of YI over the previous week by the average intake per serving. We assessed periodontal conditions using the Community Periodontal Index (CPI) and defined periodontitis as a CPI score ${\geq}3$. Multivariate logistic regression analyses were performed after adjusting for sociodemographic variables, and oral and general health behaviors and status. Results: The mean weekly YI among those without periodontitis ($1.03{\pm}0.06cups$) was significantly higher than among those with periodontitis ($0.77{\pm}0.08cups$) (P<0.001). Individuals who consumed more than 2 cups of yogurt per day were 76% less likely to have periodontitis than those who consumed less than 1 cup of yogurt per week after adjusting for all covariates (odds ratio, 0.24; 95% confidence interval, 0.10-0.60). Conclusions: We found a significant association between increased intake of semi-solid yogurt and periodontal health. We therefore recommend daily consumption of semi-solid yogurt as a probiotic to improve periodontal health. Further longitudinal studies are required to elucidate plausible mechanisms through which probiotics impact periodontal disease, considering both periodontal pathogens and clinical periodontal parameters.

Purpose: The purpose of this retrospective study was to investigate the relationships of types of dental insurance coverage in Korea with sociodemographic characteristics and the prevalence of systemic and oral diseases, as well as to evaluate the socioeconomic impact of Korean dental insurance policies. Methods: Sample cohort data from 2006 to 2015 were obtained from the National Health Insurance Service. Patients were divided into 2 groups. The exposed group comprised patients who received insurance benefits for complete dentures, removable partial dentures, and implant care, while the control group comprised patients who did not receive these benefits. The type of insurance coverage and the prevalence of systemic and oral diseases were compared between the 2 groups. Results: Patients who received benefits in the form of complete dentures, removable partial dentures, and implants had similar sociodemographic characteristics in terms of sex, age, income quintile, and type of insurance coverage to the control group. The prevalence of hypertension, anemia, renal disease, rheumatoid arthritis, osteoporosis, asthma, and cerebral infarction was higher in the exposed group than in the control group (P<0.05). The prevalence of periodontal diseases and dental caries was also higher in the exposed group. Conclusions: Korean dental health insurance policy has been beneficial for the medical expenses of low-income and elderly people suffering from a cost burden due to systemic diseases. However, since there is a tendency to avoid invasive interventions in older patients due to the high risk of systemic diseases, insurance coverage of dentures may be more helpful from a socioeconomic perspective than coverage of dental implant treatments.

Objectives: The study aims to examine the influence of university students' sociodemographic variables, parents' variables, and personal variables on their level of depression. Method: The study included a total of 334 university students enrolled in Busan. The data were used to perform correlational analysis and hierarchical regression analysis and were processed using the SPSS 23.0 program. Results: The main results of this study were as follows: First, the hierarchical regression analyses revealed that the most influential model was the model of personal variables. Among the personal variables, self-esteem was the most influential factor responsible for university students developing depression - the higher their level of self-esteem, the lower their level of depression. Among the parent variables, attachment to their father was the second most significant influence on the depression level of university students. Conclusions: This study showed that, in addition to attachment to their father, their self-esteem was highly significant in predicting university students' depression. The results of these findings have implications for future research in the form of programs and education to improve the relationship with fathers. Furthermore, the results of this study could be used to help and provide basic resources to alleviate and prevent university students' depression by strengthening their self-esteem.

Objectives: This study aimed to evaluate dietary protein intake and its adequacy among Korean adults during recent 10 years. Methods: Based on the 2010 ~ 2019 Korea National Health and Nutrition Examination Survey (KNHANES) data, a total of 51,296 adults aged 19 years old or more who participated in a one-day 24-hr dietary recall were included. Dietary protein intake was estimated as percentages of total energy (% of energy) and grams per body weight (g/kg/day) and compared with the 2020 Dietary Reference Intakes for Koreans to evaluate the adequacy of protein intake. In addition, proportions of people whose protein intakes were less than the estimated average requirement (EAR) and above the upper limit of the acceptable macronutrient distribution range (AMDR) (> 20% of energy) were calculated according to sociodemographic characteristics. Results: Protein intake was increased from 14.7% of energy in 2010 to 15.6% of energy in 2019 among Korean adults. However, there was no increase in protein intake relative to the recommended nutrient intake (% RNI) during the recent 10 years. Protein intake relative to the RNI was decreased from 130.2% in 2010 to 121.1% in 2019 (P for trend < 0.0001) among total participants, and a significant decreasing trend was observed in all age groups except for over 65 years old. However, protein intake relative to the RNI was lowest in the elderly (98.6%). Proportions of low protein intake (< EAR) and high protein intake (> AMDR) increased in the past 10 years (P for trend < 0.0001 for all), and these were associated with socioeconomic statuses, such as education and household income levels. Conclusions: These findings suggest that protein adequacy in Korean adults has not been improved over the past decade compared with recommended levels. Nutritional education and intervention programs should consider different intake levels according to sociodemographic characteristics.

Objectives: Dehospitalization of long-term inpatients with schizophrenia can be difficult because of complex factors such as chronic symptoms and low family and social support. The aim of this study was to identify factors related to dehospitalization and readmission of long-term inpatients with schizophrenia. Methods: This retrospective study reviewed the medical records of patients discharged from a psychiatric hospital in Yongin, South Korea, from February 1, 2016, to July 31, 2017. Patients who were hospitalized for over 3 months were divided into two groups: readmission (n=47) and dehospitalization (n=55). Differences in sociodemographic and clinical factors were analyzed between the two groups. Results: Regarding sociodemographic characteristics, female sex, familylessness, discharge to nursing homes, and discharge after symptom improvement were more prevalent in the dehospitalization group, whereas male sex, having a sibling as next of kin, and discharge because of other problems were more prevalent in the readmission group. Among clinical characteristics, hospital stay was longer in the readmission group. Conclusion: In this study, patients without a family showed a tendency to not be readmitted when they were discharged to nursing homes after symptom improvement. Expansion of social welfare support may encourage dehospitalization of long-term inpatients with schizophrenia.

Purpose: This study evaluated the internal structure (structural validity, internal consistency, and measurement invariance) of the Health-Related Quality of Life Instrument with Eight Items (HINT-8), developed to measure Korean people's health-related quality of life. Methods: A secondary analysis was conducted using data from the Korea National Health and Nutrition Examination Survey, involving 6,167 adults aged over 18 years. The structural validity of the HINT-8 was assessed using exploratory graph analysis and confirmatory factor analysis. Internal consistency and measurement invariance were analyzed using McDonald's omega (ω) and multigroup confirmatory factor analysis, respectively. Results: The HINT-8 had a single dimension and good internal consistency (ω =.804). The one-dimension HINT-8 exhibited matric invariance but not scalar invariance across sociodemographic groups (sex, age, education, and marital status). Further, it exhibited scalar or partial scalar invariance across medical condition groups (hypertension, diabetes, depressive symptoms, and cancer). Conclusion: The study finds that the HINT-8 demonstrated satisfactory structural validity and internal consistency, indicating its suitability for practice and research. However, the HINT-8 scores cannot be compared across different groups regarding sex, age, education, and marital status, as the interpretation varies within each sociodemographic category. Conversely, interpretation of the HINT-8 is consistent for individuals with and without hypertension, diabetes, depressive symptom, and cancer.

Taking vitamin and mineral supplements is increasingly common with the rapid economic growth. The aim of this study was to determine the prevalence of vitamin and mineral supplement use among adults aged 20 or older from the third Korean National Health and Nutrition Survey data and to explore the effect of sociodemographic and lifestyle factors as well as nutrient intake on taking supplements. People who had participated in both a health questionnaire and a nutritional survey were selected, and 2,871 men and 3,555 women were finally included in this analysis. Both men and women with a higher level of education, those residing in a metropolitan area, and those with higher income were more likely to take supplements. Health behaviors were not significantly associated with taking supplements. Mean nutrient intake of all nutrients except energy intake was not significantly different in men or women taking supplements after adjusting for age, education, marital status, resident area, smoking, and energy intake. Compared to Dietary Reference Intake (DRI) for Koreans, most vitamins and minerals, except vitamin $B_2$ and calcium, were consumed at higher than the Recommended Intake (RI) without supplements. In conclusion, taking supplements such as vitamin $B_2$ and calcium may promote health and prevent disease. However, the type and frequency of other vitamin and mineral supplements consumed should be considered with caution.

Background and Objectives : This study aims to identify sociodemographic and disease-related variables which predicts continuity of outpatient treatment after discharge among bipolar patients. Materials and Method : The medical records of patients who discharged with the diagnosis of bipolar disorder from Department of Psychiatry, St. Mary's hospital from 2005 to 2009 were reviewed. Data on sociodemographic and disease-related variables were analyzed. Results : It showed older age, higher rate of male and higher rate of being married in 1-year follow-up group than in non-follow-up group. And it showed longer duration of index hospitalization, higher rate of previous psychiatric outpatient treatment within 3 months before index hospitalization, higher rate of involuntary admission in 1-year follow-up group than in non-follow-up group. The univariate logistic regression analysis revealed that older age, being male, previous psychiatric treatment and longer duration of index hospitalization were significantly related to an increased likelihood of 1-year follow-up visits. Conclusion : Age, sex, history of previous psychiatric treatment, and duration of hospitalization seems to have influence on continuity of outpatient treatment after discharge.

The purpose of this study was to examine the paternal involvement tendency and its effect on adolescent's self-esteem for boys and girls. Subjects were 607 1st and 2nd grade middle school students in Busan. The data were analyzed by t-test, one-way Anova, Pearson's correlation, and multiple regression analysis. The results were as follows. The scores on paternal involvement were influenced by the amount of time spent with parents, 5days work a week of father, flexibility of leaving work-time of mother, regularity of holiday work of mother as well as adolescents' and fathers' sociodemographic characteristic. For boys, self-esteem was influenced by all sub-scales of paternal involvement : the leisure-life, proffering information, academic support, eveηday life, material support, discipline, and tradition-inheritance. For girls, self-esteem was influenced by leisure-life, proffering information, academic support, everyday life, and material supports.
