  • Background: The prevalence of tuberculosis is closely related to socioeconomic status. Although the nation-wide prevalence of pulmonary tuberculosis was constantly decreasing during past 30years, there were few studies about prevalence of specific social groups in Korea. We examined prevalence of pulmonary tuberculosis among university freshmen, which might represent one of the specific social groups in Korea. Methods: The prevalence of radiologically active pulmonary tuberculosis among Seoul National University(SNU) freshmen was investigated from 1988 to 1997. And those results were compared with prevalence data of SNU freshmen from 1977 to 1987 and also with prevalence of age matched general population. Results: There was continuous decrement of prevalence of pulmonary tuBerculosis among university freshmen. In 1985 and 1990, there was significant prevalence difference between university freshmen and general population. But in 1995, the prevalence of both groups was not significantly different. Conclusion: The prevalence of pulmonary tuberculosis in university freshmen has decreased steadily. The prevalence of pulmonary tuberculosis in university freshmen was lower than that of age-matched general population during past 20years. However, this trend was not evident in 1995.

  • Purpose: Obesity and headache are two highly prevalent diseases both in childhood and adolescent. In this study, we assessed the prevalence of obesity in pediatric headaches patients in a single institution in Korea, and differences according to age, sex, headache type, frequency, intensity, and disability. Methods: We retrospectively reviewed the medical records of 340 subjects (6-18 years of age) who visited the Pediatric Headache Clinic of Bucheon St. Mary's Hospital during the period from January 2015 through March 2018. Data on age, sex, height and weight, as well as headache type, frequency, intensity and disability, were collected. Body Mass Index (BMI) percentile was calculated based on the 2017 Korean Children Adolescence Growth Chart. Results: 17.6% of the pediatric headache patients were obese. The prevalence of obesity in male patients was higher than females (Male 23.8% VS Female 11.6%, P=0.002). There were no significant differences in obesity rate according to age, headache type, frequency, intensity, and disability. Conclusion: The prevalence of obesity in the pediatric headache population was 17.6% which is higher than 10.1% in general population (Korea National Health and Nutrition Examination Survey, KNHANES, 2013).

  • Heartworm infection is a fatal disease causing heart failure and pulmonary diseases in dogs. This heartworm infection can also occur in wild carnivores including Raccoon dogs. Recent study found that relatively high prevalence rate in wild Raccoon dog population. Therefore, this study was designed to evaluate the prevalence rate of D. immitis in free-roaming Raccoon dogs and the recovery rate of microfilariae in infected Raccoon dogs in Korea. Overall prevalence rate of D. immitis in Korean Raccoon dogs was 17.8%. Prevalence rate in male Raccoon dogs was 21.8%, while that in female Raccoon dogs was 12.8%. Microfilariae were not detected in 17 Raccoon dogs having positive in heartworm antigen test. Our study result suggested that the prevalence rate of D. immitis in Korea is twice higher than that of Japan. In addition, microfilaremia is rare in Raccoon dogs as commonly noticed in cats.

  • Objectives: This study is to investigate the prevalence and related factors of metabolic syndrome among Korean adults aged 20 years and above. Methods: From the database of the $5^{th}$ Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2010, data of 5,670 adults who responded to all the questionnaires of health interview and had metabolic syndrome in the health examination were included in this analysis. SAS 9.2 was used for statistical analysis with complex sample survey modules and commands. Results: The prevalence rate of metabolic syndrome based on the criteria proposed by International Diabetes Federation (IDF) was 18.8%. The prevalence of metabolic syndrome in each group was: 20.7% of women, 43.1% among elderly over 70 years old, 40.6% of the divorced or the separated, 27.6% of recipients of economic support from the government, 23.6% of people who had alcohol dependency problem, and 43.7% of overweight or obese adults. Independent risk factors based on the multiple logistic regression analysis revealed that prevalence of metabolic syndrome was associated with female (odds ratio 1.59 [95% confidence interval 1.20-2.11]), age (50s 3.95 [2.11-7.37], 60s 5.62 [2.98-10.61], 70s 10.56 [5.25-21.25]), high school education (0.52 [0.37-0.74]), clerk occupation (2.14 [1.27-3.60]), divorced marital status (1.72 [1.15-2.59]), alcohol dependency (1.86 [1.16-2.98]), higher BMI (14.08 [10.60-18.70]). Conclusions: The metabolic syndrome is prevalent among Korean adult population according to IDF criteria. Several demographic characteristics and potentially modifiable factors are associated with metabolic syndrome. Identification of this high-risk group and management of these modifiable factors are warranted to reduce the prevalence of metabolic syndrome.

  • The study found out developmental factors of the liver diseases in 29, 531 cases of the healthy adults who were diagnosed by using ultrasound at domestic healthcare centers in 6 cities. The results are as follows. Based on the result of the study, the liver diseases diagnosed by using ultrasound was revealed to show 43.1% of prevalence, and the occurrence was significantly higher in male (23.3%) than in female (19.8%). The prevalence of hepatic diseases related to the BMI was revealed to show highest prevalence of the fatty liver in obese group (BMI $\geqq$ 25) by recording 44.3%. Smoking contributed to the high prevalence of all liver diseases. Although the fatty liver was the most frequently occurred form of liver diseases by recording the prevalence of 49.1% (22.2% in male, 26.9% in female), the significant difference was found only in female (p < 0.05), but male group did not show significant difference (p > 0.05). The prevalence of hepatic diseases related to the hypertension was revealed to show highest prevalence of the fatty liver in hypertension group by recording 67.7%. The prevalence of hepatic diseases related to the diabetes was revealed to show highest prevalence of the fatty liver in diabetes group by recording 66.2%. The high prevalence of all hepatic diseases was related to diabetes mellitus with statistical significance (p < 0.001). The multiple regression analysis for the related factors which affect the prevalence of the liver diseases showed the higher prevalence by age. Sex, obesity and diabetes mellitus were positively related to the prevalence (p < 0.05) while hypertension and smoking showed no significant relationship to the prevalence of the disease (p > 0.05).

  • Purpose: The purpose of this study was to explore the relationship between milk intake and prevalence rates of chronic diseases using KNHANES data, and the significance of the relationship was tested based on meditators, socioeconomic status (income, education), dietary behaviors (smoking, alcohol drinking, breakfast, and eating out), and physical activity (walking, medium, and high). Methods: Using the 5th and 6th survey data of KNHANES, milk intake rates and presence of seven chronic diseases were summarized and analyzed by ANOVA for two groups of adult men and women as follows: hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, abdominal obesity, obesity, and metabolic syndrome. The dependent variables for the presence of seven chronic diseases regressed with socioeconomic, dietary behavior, and physical activity variables according to Logistic models. The dependent variables for milk intake using predictor variables of socioeconomic, dietary behaviors and physical activity were analyzed according to Logistic models. Finally, the significant socioeconomic, dietary behavior, and physical activity variables in the above model along with milk intake as a control variable or mediator variable regressed with significant chronic diseases according to Logistic models. Results: Milk intake, socioeconomic status, dietary behaviors, and physical activity were significantly different among the two groups of adult men and women, which were also critical factors to the prevalence of chronic diseases. The dependent variable for prevalence of chronic diseases regressed with significant factors of socioeconomic status, dietary behavior, and physical activity variables according to chronic diseases using the control or mediator variable of milk intake and summarized as follows: For adult men, milk intake controlled the education effect on diabetes partly, alcohol on hypertension and hypertriglyceridemia, low HDL-cholesterol, metabolic syndrome, breakfast on metabolic syndrome, eating out on obesity, and medium physical activity on hypertriglyceridemia. For adult women, household income on hypertriglyceridemia, diabetes, abdominal obesity, education level on hypertension, alcohol drinking, eating out, and walking activity on abdominal obesity, alcohol, breakfast, eating out, walking activity on low HDL-cholesterol, and medium physical activity on hypertriglyceridemia and low HDL-cholesterol were partly controlled by milk intake. Other significant socioeconomic status, dietary behavior, and physical activity variables related to prevalence of chronic diseases were fully controlled or mediated by milk intake. Conclusion: This study shows that milk intake (daily more than 200 g) prevents chronic diseases such as hypertension, hypertriglyceridemia, low HDL-cholesterol, diabetes, obesity, abdominal obesity, and metabolic syndrome.

  • Preschool children in Iksan city, 3-5 years old, were examined for their prevalence of severe early childhood caries. The case definition was 1 or more cavitated, filled, or missing (due to caries) smooth surfaces in primary maxillary anterior teeth. Feeding behavior and oral hygiene behavior were investigated by a questionnaire. The prevalence was 20.8% for 36-47 months, 23.6% for 48-59 months, and 30.8% for 60-71 months. Going to sleep with bottle beyond 1 year (P<0.05), immediate removal of bottle after child fell on sleep (P<0.01), beginning time of toothbrushing (P<0.01) had significant relationship with the prevalence of severe early childhood caries. Toothbrushing frequency of primary care provider and use of oral cleaning aids by primary care provider had a tendency to be related with the prevalence(P<0.10).

  • A total number of 100 fecal samples were examined for the presence of Giardia intestinalis infection in dogs using a Giardia ELISA kit (SNAP$^{(R)}$ test, IDEXX Laboratories, Inc., Westbrook, ME). 49 males and 51 females were examined for a G. intestinalis infection in Daejeon and Chungnam area of South Korea. The overall positive rate of G. intestinalis infection was 12.00%. G. intestinalis infection resulted to be more prevalent in males (12.24%) than in females (11.76%), and in symptomatic dogs (18.18%) than in asymptomatic dogs (11.54%). There were no significant differences between the two groups. 19.60% being found in the < 2-year-old group, 4.08% in the over 2 year-old group. $X^2$ analysis revealed a significantly higher prevalence (p < 0.05) in the < 2-year-old group than in the other, and a significantly higher prevalence in dogs kept in a shared kennel (36.00%, p < 0.001). This study is the first survey of G. intestinalis infection prevalence in South Korea according to life style (particularly between dogs kept in a shared kennel and that of dogs kept separately) using an ELISA kit, and this study is expected to provide a useful reference for clinicians and breeders.

  • Korea Health Panel (KHP) data and Korea National Health and Nutrition Examination Survey (KNHANES) data are collected by self-assess and self-report for individual's health status and medical use. Previous studies have claimed that the reliability for prevalence rates and health life expectancies obtained from these data should be validated. National Health Insurance Services in Korea recently released a sample cohort DB that contain all data related to the use of medical facilities for all entire Korea citizens. It has been shown that disease-specific prevalence rates calculated from these data are representative and reliable for the entire population. In this paper, we evaluate the reliability of prevalence rates derived from self-reported data such as KHP and KNHANES by comparing to the prevalence rates from the sample cohort DB. We found that both KHP and KNHANES underestimate prevalence rates and in turn overestimate health life expectancies. Moreover, the general trends of health life expectancies might be distorted (except for the sample cohort DB) because of sampling and non-sampling errors.
