Purpose: This study examined the effects of a mobile app-based program to reduce the dietary sugar intake according to the stages of the behavioral change in dietary sugar reduction in female college students. Methods: The program used in this study can monitor the dietary sugar intake after recording the dietary intake and provide education message for the reduction of dietary sugar intake. In an eight-week pre-post intervention study, 68 female college students were instructed to record all the food they consumed daily and received weekly education information. At pre-post intervention, the subjects were asked to answer the questionnaire about sugar-related nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. For statistical analysis, ANOVA and a paired t-test were used for comparative analysis according Precontemplation (PC), Contemplation Preparation (C P), and A M (Action Maintenance) stage. Results: Significant differences were observed in the frequency of snacking, experience of nutrition education, and preference for sweetness according to the stages of behavior change in dietary sugar reduction. After finishing an intervention, the sugar-related nutrition knowledge score was increased significantly in the stages of Precontemplation (PC) and Contemplation Preparation (C P). The score of the sugar intake behavior increased significantly in all stages. The intake frequency of chocolate, muffins or cakes, and drinking yogurt decreased significantly in the PC stage and the intake frequency of biscuits, carbonated beverages, and fruit juice decreased significantly in the C P stage. Subjects in the PC and C P stages had an undesirable propensity in nutrition knowledge, sugar-intake behavior, and sugar-intake frequency compared to the A M stage, but this intervention improved significantly their nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. Conclusion: This program can be an effective educational tool in the stages of PC and C P, and is expected to further increase the usability and sustainability of mobile application if supplemented appropriately to a health platform program.

Objective : Patients with sleep apnea should be diagnosed with polysomnography(PSG). However, it is not easy to recommend PSG for all patients suspected with sleep apnea in practice. Therefore, we tried to develop the screening test for referral of PSG. Method : 140 patients with snoring and sleep apnea syndrome were studied by the PSG. Sleep apnea questionnaire. Zung's scale for depression. Stanford Sleepiness Scale(SSS), insomnia scale and neuropsychological test were administered. Also, blood pressure, height, weight and neck circumference were measured and some histories were taken. Correlations between respiratory disturbance index(RDI) and various parameters mentioned above and discriminant coefficients of the parameters to RDI were computed. And, we investigated sensitivities of screening tests for selection of the patients with RDI above 20. Results : Using six parameters(neck circumference, systolic blood pressure before sleep, degree of alcohol drinking, frequency of breath-holding during sleep, degree of dry mouth during sleep, sleep apnea score), the patients with RDI above 20 could be discriminated in 92.8% sensitivity. In case of more than two among six parameters(neck circumference of above 40cm, systolic blood pressure of above 125mmHg, frequent alcohol drinking, frequent breath-holding during sleep, frequent dry mouth during sleep, sleep apnea score of above 35), same patients could be discriminated in 87.6% sensitivity. And, in case of more than one among four parameters(neck circumference of above 40cm. systolic blood pressure of above 125mmHg, frequent alcohol drinking, body weight of above 80kg), discrimination sensitivity was 83.5%. Conclusions : Patients with RDI above 20 could be discriminated by above parameters with high sensitivity. Therefore, the screening test using above parameters can be applied in selection of the patients with sleep apnea for PSG in practice.

This study aimed to investigate the relationships between depressed mood and life style patterns, including smoking, alcohol drinking, and physical inactivity in Koreans aged 40 years, which is a critical life transition period. Based on the Life Transition Period Health Examination at the Korea Association of Health Promotion conducted in 2011 (n=27,684), participants were categorized into a depressed mood group and a non-depressed mood group based on the results of the Primary Mental Health Questionnaire. The depressed mood group showed higher tendency for smoking compared to the non-depressed mood group. Current and ex-smokers were about twice as likely to have a depressed mood as the non-smokers. The prevalence of nicotine dependency was significantly higher in the depressed mood group. The number of days and amount of alcohol consumption were significantly correlated with depressed mood. The prevalence of alcohol dependence and alcohol abuse was higher in the depressed mood group than in the non-depressed mood group. The frequency of high-intensity exercise per week was negatively correlated with the number of people with a depressed mood. This study showed the significant relationships between depressed mood and smoking, alcohol drinking, and physical activity in adults during an important life transition period. This implies that the development of proper lifestyle intervention or education may be needed to prevent depressed moods in this age group.

This study was performed to assess the effects of beverage consumption on nutrient intake and anthropometric measurements. Beverage intake and dietary intake were measured by a beverage frequency and quantity questionnaire and three 24-hour dietary recalls in 160 elementary school students in the Gyeongnam area. The number of drinking moments per month was 93.5 and drinking amount of all beverages was 626.6 mL per day. The amount of milk intake was 253.8 ml per day, which was the highest in all types of beverage consumption, followed by juice(133.6 mL), and carbonated beverage(77.7 mL). The amount of sweetened beverage which was defined as all beverages except milk and soy milk was 359.7 mL per day. Energy intakes from all kinds of beverages and sweetened beverages accounted for 20.3% and for 10.5% of the daily energy intake, respectively. The contributions of sweetened beverage intake to the daily energy intake in girls accounted for 13.5%, whereas in boys it was 7.7% and significantly lower. The number of drinking moments and the contribution of sweetened beverage intake to daily energy intake were negatively correlated with protein, vitamin A and niacin intake, respectively. The consumption of milk and soybean milk combined showed a significant negative correlation with the body fat ratio(%) and it also negatively correlated with waist-hip girth ratio(WHR). However, the sweetened beverage intake was not related any of the anthropometric measurement. In conclusion, consumption of the sweetened beverage dropped the nutritional quality of diet. However it was not related with anthropometric measurements in elementary students.

The purpose of this study was to investigate the factors affecting hearing loss in adolescent's use of PCPs, and to give the basic data for adolescent's hearing conservation program development and prevention education against their hearing loss. This study was a descriptive research about three factors affecting hearing loss; the knowledge and attitude about noise, the perception of hearing loss and the hearing threshold. The subjects of this study were 383 students in two general high schools and two vocational high schools in Teagu. They have been using PCPs but with no current or past ear disease. This study was carried out from Sep. 1. 2000 to Oct. 24, 2000. The instrument used for the knowledge and attitude about noise was a questionnaire developed by Rhee. Kyung Yong and Yi. Kwan Hyung(1996). The instrument used for the perception of hearing loss was a Smith Hearing Screening Questionnaire. A Belton Model 112 Audiometer. air-conduction hearing test instrument. was used for the hearing threshold. Data was analysed by a SPSS/Win 10.0 program with frequency. percentage, t-test. ANOVA and pearson correlation. The results of this study were as follows; 1. The average of concern about hearing scored the highest $3.66{\pm}0.70$. The average of perceived susceptibility scored $2.64{\pm}0.85$ and the average of knowledge about noise scored $2.13{\pm}0.56$. The average of total knowledge and attitude about noise scored $2.82{\pm}0.46$. The average of discomfort of hearing loss($2.51{\pm}0.81$) scored higher than that fear of hearing loss($1.35{\pm}0.53$). The average of total perception of hearing loss scored $1.93{\pm}0.59$. The hearing threshold of the subjects scored the highest at 500Hz(Lt. $23.21{\pm}6.62$, Rt. $23.39{\pm}7.02$) and scored higher in order of 1000Hz, 2000Hz, 4000Hz and 8000Hz. 2. The knowledge and attitude about noise and the perception of hearing loss were both affected only by one important characteristic, which was general and vocational high schools. The knowledge and attitude about noise raked (t=5.258, p=0.000), and perception of hearing loss raked(t=2.241. p=0.026). However. several other important characteristics also impacted significantly on the knowledge and attitudes about noise. They included grade (t = 1. 987. p=0.048), father's education(F=2.745. p=0.043), marks(F=3.157, p=0.044), drinking(t=2.307, p=0.022) and smoking(t=2.587, p=0.010). The left hearing threshold differed significantly by sex at 1000Hz(t=5.175, p<0.001) and 8000Hz (t=3.334, p<0.01). According to general and vocational high schools (p<0.001), at 500Hz (t=-5.056), 1000Hz (t=-5.253), 2000Hz (t=-4.905), 4000Hz (t=-4.704) and 8000Hz (t=-5.204) significant differences were also shown. Marks were significant at 1000Hz (F=3.824, p<0.05) and drinking was found to be significant at 500Hz(t=2.203, p<0.05). The right hearing threshold differed significantly by sex at l000Hz(t=5.557. p<0.001). 4000Hz(t=2.234. p<0.05) and 8000Hz (t=2.730. p<0.01). According to general and vocational high schools(p<0.001) at 500Hz (t=-4.730), 1000Hz(t=-6.271). 2000Hz (t=-4.573). 4000Hz(t=-3.554) and 8000Hz (t=-3.405) significant differences were also shown. Grades impacted at 500Hz(t=2.201. p<0.05) and 4000Hz(t=2.511. p<0.05), while marks were significant at l000Hz(F=4.1l5. p<0.05) and drinking was significant at 500Hz(t=2.333. p<0.05). 3. The left hearing threshold in accordance with use of PCPs differed significantly at 2000Hz(F=2.996. p=0.03l) according to volume level and at 8000Hz(F=2.197. p=0.022) according to duration${\times}$hours per day. The right hearing threshold differed significantly at l000Hz(F=3.075. p=0.028) according to volume level and at 8000Hz(F=2.925. p=0.034) according to duration. 4. The knowledge and attitudes about noise showed a light positive correlation with the perception of hearing loss. A positive correlation was shown. as stated previously in all Hz, between the left hearing threshold and the right hearing threshold, especially the highest correlation at 2000Hz(r=0.761. p=0.000). This study has shown that the factors related to adolescent's use of PCPs are important as they impact significantly an adolescent's hearing. These results then indicate that in future, when designing a hearing conservation program and prevention education this data should be considered.

Objectives : The study aimed to identify factors associated with suicidal attempt in Korean adults experiencing thoughts of suicide. Methods : This study analyzed outcomes of suicidal behavior in the Korea National Health and Nutrition Examination Survey (KNHANES) 2015, 2017, and 2019. This survey was administered by the Korea Centers for Disease Control and Prevention (KCDC). The suicidal idea group was divided into individuals who had attempted suicide (n=92) and those who had not (n=831). Complex samples crosstabs analysis was conducted to compare the two groups' sociodemographic, psychiatric, and clinical characteristics. In addition, factors related to attempted suicide were investigated using complex samples logistic regression analysis. Results : The attempted suicide group had significantly higher rates of depression, recent psychiatric counseling, and suicidal plan (p<0.001) than the non-attempting group. In addition, the groups differed significantly in the frequency of binge drinking and smoking (p<0.05). Adjusted multivariate analysis revealed that the presence of a suicidal plan (Odds ratio [OR]=8.46, 95% Confidential Intervals [CI]=4.72-15.00), daily binge drinking (OR=3.14, 95% CI=1.26-7.84), psychiatric counseling within the past year (OR=3.03, 95% CI=1.75-5.23), low income level (OR=2.89, 95% CI=1.17-7.10), and history of depression (OR=2.39, 95% CI=1.29-4.42) were significantly associated with suicidal attempt. Conclusions : Factors associated with suicidal attempt among suicidal ideators in the general Korean population were identified across all sociodemographic, psychiatric, and clinical variables. Assessment of and intervention in suicidal plan, binge drinking, income level, and depression might prevent progression to suicidal attempt among those contemplating suicide.

To investigate the effect of eating habits and lifestyle on the food intake of university students in Daejeon, 104 male students(26.75％) and 282 female students(73.75％) were surveyed about their food intake, eating habits, and lifestyle using the questionnaire. The major food served as breakfast was steamed rice(76.05％) and there was a little significant difference between male and female. The major food served as lunch was also steamed rice(73.77％) and male students ate it more than female ones. According to the survey, 41.95％ of the subjects had breakfast regularly, and 24.35％ seldom, which showed no significant difference between male and female. In case of lunch, the percentile of subjects(54.55％) who had regularly eaten lunch was more than that of breakfast, and there was a little significant difference between male and female. The survey said most subjects(49.22％) had eaten dinner irregularly, which rate was higher in male students. The meal skipped usually was the breakfast(24.35％), which rate was higher in female students. The reason why the subjects skipped the meal was mainly due to the lack of sufficient time for breakfast and lunch, and for dinner to the weight loss. Among the subjects, 80％ said they were non-smokers; 96.44％ in female students and 35.58％ in male ones. In case of drinking, most subjects said they sometimes drank(67.19％) and the frequency of drinking was once or twice a month(51.99％), which showed the significant difference between male and female. In the aspects of effects of drinking and smoking on the food intake, the drinking practice after eating was shown to be the highest(55.98％); smoking generally affected the food intake, which showed the difference between male and female. Food intake during the examination period didn't show any differences to the usual one or increased a little bit, which showed a difference between male and female. Losing appetite during the examination period was shown mainly in the female students. When they felt blue or tired, the food intake decreased, which showed a significant difference between male and female was shown. When feeling good, the food intake significantly increased, which showed a significant difference between male and female. Therefore, there was a significant difference between male and female in the actual eating habits and in the aspects of food intake.

Objectives: Excess sodium intake has been linked to obesity and obesity-related indices. However, the scientific evidence for this association is inadequate. The purpose of this study was to investigate the association between urinary sodium excretion and obesity-related indices among Korean adults. Methods: A convenience sample of 120 subjects (60 obese and 60 non-obese subjects) were recruited applying frequency matching for sex and age between two groups. Sodium intake level was assessed through 24-hour urine collection. Obesity-related metabolic risk factors, including fasting blood lipid indices, subcutaneous and visceral fat through computed tomography (CT), insulin resistance indices, blood pressure and liver enzymes were measured in all subjects. These obesity-related metabolic risk factors were compared between obese and non-obese group according to sodium excretion levels (<110 mEq/day, 110~180 mEq/day, >180 mEq/day). Results: After adjusting for age, gender, health behaviors (smoking, exercise, drinking), and energy intake, several obesity-related metabolic risk factors, including abdominal circumference, body fat percentage, subcutaneous and visceral fat, triglyceride, and systolic blood pressure were found to be significantly deteriorated as the sodium excretion level increases. In addition, multivariate adjusted-odds ratios of abdominal obesity, high blood triglyceride, and high blood pressure were found significantly higher in the highest sodium excretion group compared to the lowest group. The mean number of metabolic syndrome risk factors was also significantly greater in the highest sodium excretion group than in the lowest group. Conclusions: The current study findings suggested that high sodium intake can affect obesity and metabolic syndrome risk negatively, implying the necessity of future research on low-sodium diet intervention in relation to obesity and related health problems.

Purpose: The purpose of this study is to investigate the status of oral health behaviors and oral health status, and to analysis the association between health behavior and chronic disease and oral health status of male workers. Methods: The survey used structured self administered questionnaires from September to October in 2009 in Daegu and Gyeongsangbuk-do province, randomize thirty workplace which work more than 50 workers and carry out a survey targeting 30 to 50 age male laborers who work selected workplace. Total of 1,532 replies were analysed. Results: Age, education, monthly income, job was significantly associated with number of toothbrushing, scaling experience, number of missing teeth. Smoking, amount of smoking, frequency of drinking, number of tooth brushing, unmet need and subjective oral health condition, HBP and DM was significantly associated with the number of missing teeth. In logistic regression, age(above 40), monthly income and DM were significant factors on loss of teeth. Conclusion: In conclusion, it is important to provide education on the teeth-brushing and DM management to workers engaged in a small or medium sized workplace with many tooth loss and low educational status, and to recommend a regular scaling as well as to establish policy for creating conditions upon an oral health check-up and a tooth scaling and allow the maintenance of an oral health.

This research had the following results after analyzing the questionnaires and the survey on 51 people experienced smoking and 51 people unexperienced smoking out of patients who participated in the practice hours of Department of Dental Hygiene to study the relevance between smoking which is one of the partial factors of oral disease and oral health. 1. 78.4% of patients smoke more while drinking, which level is still high, so it threatens the oral health. 2. 22.5 % of patients had the experience of scaling within recent 1 year, which level is still low. 3. The people who experienced smoking realized the harmfulness of smoking and during the toothbrushing, the level of self-consciousness about halitosis and bleeding gum is higher than the unexperienced. 4. The frequency of smokers' toothbrushing on the average a day is lower than non-smokers. 5. Simplified oral hygiene index of men(4.98) is higher than woman(4.00) and the people experienced smoking(4.59) is higher than the unexperienced(4.18), which means that man and the person who experienced smoking has the bad oral environment.
