Objectives: The purpose of this study was to determine if self-rated oral health differed according to self-reported oral health behaviors in Korean adolescents. Methods: The raw data of 'The 6th Youth Health Behavior Online Survey' carried out by the Korea Center for Disease Control and Prevention were analysed. Independent t-test, one-way ANOVA, and Logistic regression analysis were used to assess the relationships between oral health behaviors and self-rated oral health (n=73,238). Results:Oral health behaviors had stronger influence on daily toothbrushing habits. In particular, participants who brushed their teeth in the morning and participants who brushed their teeth more than 3 times a day were more likely to have good self-rated oral (P<0.001). Conclusions: Korean adolescents with high self-rated oral health reported practicing good oral health behaviors. These results highlight the need for the further practicable oral health education programs.

This study aimed to design and operate a complementary integrated health management program based on the connection between the hypertension and diabetes management programs and the oral health programs at a public health center. It also proposed to suggest the phased evaluation indicators. In this study, 48 adults registered in the hypertension and diabetes management program were selected from the Gangneung public health center. The clinic-specific programs were led by dental hygienists and operated for visitors twice every two weeks. The programs were designed based on the logical model, and indicators for evaluating the structure, process, and outcome were presented and applied to the input, process, output, and outcome. The evaluation indices consisted of quantitative and qualitative indicators, and the planning and operation, goal achievement, and effect of each program were assessed. The process evaluations were assessed by the appropriateness of the managers and the operating fidelity of the programs. Indicators for evaluating the outcomes were gingival bleeding, oral health knowledge, oral health awareness, and the satisfaction of the participant and the manager. The clinic-specific programs resulted in positive changes in the evaluated outcomes. The integrated health management of visitors to the hypertension and diabetes management program is important as the general and oral health has common risk factors. Furthermore, long-term operation and continuous monitoring of oral health programs are necessary to evaluate the common factors in chronic disease management.

The purpose of the present study was to elucidate such a relationship by comparing the indices of obesity, liver function, and hyperlipidemia with & without fatty liver by using data from health check-up for the adult males in a university hospital. Study subjects were 772 adult males of 30 years and over, who underwent health package check-up at the health promotion center of a university hospital. The prevalence rates of fatty liver of study subjects were 25.5%, and this study shows that fatty liver by abdominal ultrasound has a close correlation with indices of obesity(body weight, BMI, body fat, waist to hip ratio, & waist to stature ratio), liver function(AST, ALT,& GGT), and hyperlipidemia(TG, TC, & HDL-C), and that was independent of age that was relevant.

Recently, several studies conducted for other countries show that housing price has very close relationship with personal or neighborhood level obesity. Also these studies suggest the use of housing price as a new SES(Socio-Economic Status) variable for health related studies. In this study, whether this relationship can be found in regions of the Seoul Metropolitan Area is investigated. The results of this study show that, as in the cases of other countries, the regions with SES represented by higher housing prices show lower obesity levels. Further, the results show that the differences in regional housing prices well explain the variations of regional obesity levels as other traditional SES variables do. This finding indicates that housing price which is objectively, continuously, and spatially measured in Korea can be used as a new SES indicator for health research in Korea.

This study aimed to investigate the association between plant protein intake and health-related quality of life (HRQoL) in Korean individuals aged 50 years or older. Using the 2016-2018 Korea National Health and Nutrition Examination Survey data, 7,956 participants (3,434 men and 4,522 women) were included in the study. HRQoL was measured using the Euro-quality of life five-dimension (EQ5D), composed of physical function, self-care, daily activities, pain/discomfort, and anxiety/depression problems. The EQ5D estimates were converted into an EQ5D index score. The association between daily intake of plant proteins and HRQoL was evaluated using regression analysis. The intake of total plant protein, legume nut seed (LNS), and fermented bean (FERMB) proteins were all positively associated with HRQoL in both men and women (p < 0.01). Of EQ5D's five dimensions, physical function and daily activities were most commonly associated with plant protein intake. Compared to LNS protein or FERMB protein intake, total plant protein intake showed a better association with HRQoL. In conclusion, a significant association was observed between plant protein intake and HRQoL. It suggests that adequate intake of plant protein might be helpful for the maintenance or improvement of HRQoL in Korean adults.

흡연여부를 감별하는 지표가 있지만 반감기 등 여러 가지 요인에 따라 결과가 변한다는 단점이 있다. 그렇기 때문에 흡연여부 감별 시 외부요인에 영향을 덜 받는 지표가 필요하게 되었다. 그래서 흡연 여부 감별하는데 적합한 모형을 찾아 외부요인에 영향이 적은 지표를 개발에 도움이 될 것을 기대하며 연구를 진행하였다. 실험은 국민건강보험공단에서 제공한 건강검진정보데이터를 기반으로, SVM, Logistic Regression, KNN 등의 머신러닝 모델을 이용하여 흡연 여부를 감별하는 것을 진행한다. 이 실험은 속성에 따른 모형의 성능변화와 학습데이터 수에 따른 모형의 성능변화에 대한 2가지 측면에서 모델의 성능을 측정하였다. 모델의 평가는 정확도(accuracy), 정밀도(precision), 재현율(recall), 조화 평균(f1-score)으로 진행하였으며, 약 70퍼센트 정도의 정확도와, 60퍼센트 대의 재현율을 보인다. 실험 결과, SVM이 속성에 따른 모형의 성능 변화 실험에서는 63%의 재현율, 학습데이터 수에 따른 성능 변화 실험에서는 68%의 재현율을 보여, 흡연자 판별에 가장 좋은 성능을 보였다. 또한 재현율을 기준으로 실험 차수별로 가장 좋은 성능을 보인 모델과 가장 저조한 성능을 보인 모델의 차이를 비교한 결과, '속성에 따른 모형의 성능 변화 실험'에서는 최고 36%의 차이를 보였으며, '학습데이터 수에 따른 성능 변화 실험'에서 최고 42%의 차이를 보여 주었다. 이에 판별을 위한 속성도 중요하지만, 적합한 모형 선택 또한 중요하다는 것을 확인하였다.

Background: Abdominal obesity as measured by waist-to-height ratio (WHtR) may have stronger and inverse associations with cardiovascular (CV) health than overall obesity as measured by body mass index (BMI). However, there was some challenges for controversies. We aimed to examine the associations of WHtR and BMI with CV health among Korean children using data of the 2010-2012 Korea National Health and Nutrition Examination Survey. Methods: A cross-sectional study was conducted with the sample of 2,363 children by analyzing by gender and two-age groups (10-12 and 13-18 years). Overall obesity was categorized into 3 groups by BMI percentile: non-overweight (<85), overweight (${\geq}85$), and obesity groups (${\geq}95$). Abdominal obesity was categorized into 2 groups by WHtR: normal (<0.5) and abdominal obesity groups (${\geq}0.5$). The CV health score was defined as a z-score by calculating the sum of 7 CV factors. Results: The overweight/obesity groups had significantly lower CV health scores than the normal group (P<0.05) in boys and girls aged either 10-12 years or 13-18 years after adjusting for covariates. The abdominal obesity group also showed significantly lower CV health scores than the normal group (P<0.05) in all the groups; this significant association remained significant in boys aged 13-18 years even after further adjusting for BMI category (P<0.01). Conclusions: Among boys aged 13-18 years, abdominal obesity as measured by WHtR was significantly and inversely associated with CV health, independent of BMI category. Therefore, it should be considered to assess the level of abdominal obesity as a measure of CV health in late adolescent boys.

This study confirmed the validity of the health score(HS) calculation methodology and results. HS is an index that scores the degree of personal health by applying clinical standards and statistical function to health check-up items. It's calculated by the total size of the biomarker on the health change, the influence on the health change, the weight change rate according to the degree of outlier, and the standardized value. In order to confirm the validity of the results, several diseases were selected and HS was compared between the disease occurrence group and the disease absence group. And by segmenting the ranked HS, the disease incidence rate was compared. As a result, in all selected diseases, the difference in the mean of HS was significant according to the presence or absence of disease, and the incidence of selected diseases showed a tendency to increase as HS decreased.

Recently, with the development of advanced medical technology and the introduction of most advanced medical equipments, life expectancy increases accordingly. Many people want to live long-lived in health. Therefore, if it is possible to pre-diagnose the sub-health condition and formulate an appropriate treatment plan, we can prevent the disease and reduce social expenditure costs. In this study, we statistically analyzed the data in responding to each questionnaire for healthy biorhythm and sub-health among targeted members of a specific group. The analysis for the effects of healthy biorhythm to male and female showed that there was a significant difference between male and female. In the analysis of the effects of the conditions of healthy biorhythm to the 10 sub-health indicators, the significant effects of good and bad condition has been observed. The results of the decision tree analysis showed that all the respondents with poor hormone and urological sub-health status have bad healthy biorhythms. In summary, in this paper we have shown that it may be possible to improve the sub-health condition and prevent disease in advance if the healthy biorhythm is well controlled.
