The purpose of this study was to examine factors related to the oral health by stress in college women. This survey was conducted between June 16, 2014 and July 18, 2014 to investigate the correlation between stress and oral health Data were obtained from 393 women students of 5 colleges in Gwangju and Jeollanam-do. The oral health of college students is related with the stress which has a correlation between oral condition satisfaction(-) and inconvenient(+) of mastication and pronunciation (p<0.01). Also, factors affecting stress are discomfort during mastication and oral state satisfaction and discomfort during mastication. The discomfort during mastication showed the highest stress while the higher status of oral satisfaction showed lower stress (p<0.05). Therefore, college women stress is related with oral health. Colleges should consider developing a program which can appropriately manage and regulate stress to relieve their stress.

This study was conducted to determine which factors would predict metabolic syndrome (MetS) perception and exercise by applying a machine learning classifier, or Extreme Gradient Boosting algorithm (XGBoost) from July 2014 to December 2015. Data were obtained from the Korean Community Health Survey (KCHS), representing different community-dwelling Korean adults 19 years and older, from 2009 to 2013. The dataset includes 370,430 adults. Outcomes were categorized as follows based on the perception of MetS and physical activity (PA): Stage 1 (no perception, no PA), Stage 2 (perception, no PA), and Stage 3 (perception, PA). Features common to all questionnaires for the last 5 years were selected for modeling. Overall, there were 161 features, categorical except for age and the visual analogue scale (EQ-VAS). We used the Extreme Boosting algorithm in R programming for a model to predict factors and achieved prediction accuracy in 0.735 submissions. The top 10 predictive factors in Stage 3 were: age, education level, attempt to control weight, EQ mobility, nutrition label checks, private health insurance, EQ-5D usual activities, anti-smoking advertising, EQ-VAS, education in health centers for diabetes, and dental care. In conclusion, the results showed that XGBoost can be used to identify factors influencing disease prevention and management using healthcare bigdata.

The purpose of this study was to evaluate smoking patterns, oral health behavior and perception of dental healthcare of military personnel in the South Korea Army. All 367 subjects were surveyed by the structured questionnaires with convenience sampling method. The questionnaires were consisting of 22 items. Depending on the conditions of military training, the distribution and differences of smoking patterns and oral behaviors were evaluated by frequency test, Weighted Kappa, Paired t-test and ANOVA. The differences of oral health perception on smoking were demonstrated by Mantel-Haenszel Chi-square test. In addition, Generalized Estimating Equation (GEE) was used to estimate the effects of oral behavior for the conditions of military training and smoking. The number of cigarette during military training period was similar to that during non-military training (p=0.109). The perception of smokers such as smoking effect on oral health, oral health and systemic health, and need of education for smoking cessation was significantly lower than non-smokers (p=0.0095, p=0.0007, and p<0.0001). The probability that toothbrush frequency per day was only one was associated with higher during military training period than non-military training (OR=9.29, 95% CI 5.05-17.07). Moreover, the probability that hours of toothbrush were less than one minute was associated with higher during military training than non-military training (OR=2.19, 95% CI 1.78-2.71). To improve knowledge, attitude, and behavior of oral health for the members, the army needs to develop oral health education and tobacco cessation programs. In particular, motivation and practice for oral health care are required to improve poor oral health behavior during the military training.

Workers' oral health is important to guarantee workers' right of health and increase productivity. The aim of this study was to investigate recognition and satisfaction of national oral examination for workers in Incheon and Daejeon. Three hundred seventy-nine workers who were selected by convenience cluster sampling answered the questionnaire about experience, recognition and satisfaction of national health examination and oral examination by self recording type. A total of 76.0 percent of the subjects had national health examination, and 51.7% had national oral examination. A total of 64.9 percent had experienced notice about national health examination from the company, and 28.2% about national oral examination. The subjects had high positive score about intention of treatment, dental scaling, and change of toothbrushing method depending on oral examination, need of national health and oral examination, and usefulness to one's health through national health and oral examination. Office workers, regular workers, and the workers with monthly income more than 2 million won had more notice about national health and oral examination compared with sales and production workers, contract workers and the workers with monthly income less than 2 million won. We suggest institutional management of the notice about national oral examination be needed, especially for economically poor, or contract workers to increase the ratio to have national oral examination.

Background: Electronic cigarette (e-cigarette) has rapidly increased. Even though e-cigarettes are actually not smoking cessation alternative supplies, some people perceive them as smoking cessation alternative supplies. The purpose of this study is to identify the relationship between e-cigarette experiences and smoking cessation behaviors among Korean adults. Methods: Cross-sectional data was collected from 7,550 participants of Korea National Health and Nutrition Examination Survey in 2014. A total of 867 participants who were current smokers were enrolled in this study. Multi-variable logistic regression analysis were performed to identify the relationship between the smoking cessation behavior and the e-cigarette experience. Results: The e-cigarette experience rate of current smokers was 22.1%. The e-cigarette experience rate was higher in groups with the higher income, the higher education level, and the white collar jobs. Smokers with experience of smoking cessation (odds ratio [OR], 3.03; 95% confidence interval [CI], 1.67 to 5.76) and with intention to smoking cessation in the future (OR, 1.59; 95% CI, 1.05 to 2.43) were more likely to experience the e-cigarette. Especially, smokers who used smoking cessation alternative supplies were more likely to experience the e-cigarette than smokers who did not use it (OR, 2.87; 95% CI, 1.59 to 5.18). Conclusion: We confirmed that e-cigarette experiences were associated with smoking cessation experience, smoking cessation plan, and use of smoking cessation aid among smokers in Korea. Additional studies should be continued to confirm whether e-cigarette are continuously influencing the smoking cessation of current smokers in South Korea as one of the smoking cessation alternative supplies.

The purpose of this study was to investigate the association between antioxidant food intake pattern and asthma control status in Korean adolescents. This study was conducted using data from 1,578 patients diagnosed with asthma among the participants in the 11th online health behavior survey. Statistical analyses were performed for sociodemographic variables, known risk factors for asthma worsening, and all variables which were related to food intake pattern. For final decision, logistic regression analysis was used to estimate the associations between antioxidant food intake and asthma worsening. Male gender and smoking experiences were associated with asthma exacerbation. Low intake of antioxidant foods status also significantly increased asthma exacerbations. Antioxidant food intake and smoking prevention education is important for adolescent asthma patients. It is highly needed to recommend taking fruits and vegetables properly.
