This study was conducted to compare the frequency and to find epidemiologic characteristics of the diseases by analyzing the results of routine first health examination for partial healthy public officials. The total number of the examined was 1.128(876 male, 252 female) The results were as follow; 1. The prevalence rate of suspicious disease was liver disease 5.9% hypertension 5.4%, hyperlipemic disease 3.8%, pulmonary tuberculosis 1.2% by order. 2. The mean systolic blood pressure and diastolic blood pressure showed increasing trend by age increasing. The mean of blood pressure in man was rather higher than that in woman. 3. The prevalence rate of suspicious borderline hypertension increased by aging. And the distribution of high cholesterol group and over than overweight group increased by aging. 4. In male, significant relation among age, systolic blood pressure, diastolic blood pressure, relative body weight was found. And significant relation between total cholesterol level and relative body weight was found. In female, age and relative body weight was related to systolic blood pressure, diastolic blood pressure and total cholesterol level. 5. According to the retrospective follow-up for those who had suspicious disease, correspondence rate of results was 5.2% in circulatory disease and 1.5% in liver disease.

Blood pressure distribution of adolescents and its several related factors including obesity were investigated through blood pressure measuring by automated oscillometric method, anthropometry, and questionnaire. Subjects were 480 female and 480 male middle school students living in Taejon. Mean values of systolic(SBP)/diastolic(DNP) blood pressure of male and female students were 118.4$\pm$11.0/69.5$\pm$9.6 mmHg and 116.9$\pm$10.4/69.5$\pm$8.6 mmHg, respectively. Their blood pressures, particularly SBP, increased with age and showed higher value in the males than in the females. All frequency distributions of SBP and DBP, by sex and age, showed normal curves and their 50th, 90th, and 95th percentiles were presented. As obese index increased, both SBP and DBP were elevated and the prevalence of hypertension which was classified by Task Force Report(1987) increased, particularly in male students. Body weight and BMI were positively correlated with both SBP and DBP, and hight was also positively correlated with SBP or DBP. Our data inicated that blood pressure and hypertension prevalence of adolescents tended to increase and various internal and external environmental factors affected them. It was emphasized that blood pressure measurement should be done in every medical examination of adolescents and the nationwide Korean standard of blood pressure for adolescents have to be prepared.

Objectives: Self-reporting can be used to determine the incidence and prevalence of hypertension (HTN). The present study was conducted to determine the validity of self-reported HTN and to identify factors affecting discordance between self-reported and objectively measured HTN in participants in the Ravansar Non-Communicable Diseases (RaNCD) cohort. Methods: The RaNCD cohort included permanent residents of Ravansar, Iran aged 35-65 years. Self-reported data were collected before clinical examinations were conducted by well-trained staff members. The gold standard for HTN was anti-hypertensive medication use and blood pressure measurements. The sensitivity, specificity, positive and negative predictive values, and overall accuracy of self-reporting were calculated. Univariate and multivariate logistic regression were used to examine the discordance between self-reported HTN and the gold standard. Results: Of the 10 065 participants in the RaNCD, 4755 (47.4%) were male. The prevalence of HTN was 16.8% based on self-reporting and 15.7% based on medical history and HTN measurements. Of the participants with HTN, 297 (18.8%) had no knowledge of their disease, and 313 (19.9%) had not properly controlled their HTN despite receiving treatment. The sensitivity, specificity, and kappa for self-reported HTN were 75.5%, 96.4%, and 73.4%, respectively. False positives became more likely with age, body mass index (BMI), low socioeconomic status, and female sex, whereas false negatives became more likely with age, BMI, high socioeconomic status, smoking, and urban residency. Conclusions: The sensitivity and specificity of self-reported HTN were acceptable, suggesting that this method can be used for public health initiatives in the absence of countrywide HTN control and detection programs.

The purpose of this study was to compare the nutrient intake of elderly according to their cohabitation status and determine its effects on the prevalence of anemia. Data from the KNHANES were used for this study, including raw data on socioeconomic characteristics, nutrient intake, health status, and clinical laboratory findings. Study subjects aged 60 to 80 years were retrieved and analyzed. As a result, the prevalence of anemia was 12.0% (men, 11.6%; women, 12.3%). The prevalence rate increased with age, and odds ratio [OR] of anemia among those aged 75 to 80 years was 4.16 times higher in men (OR=4.16, 95% confidence interval [CI]=2.48-6.97) and 2.77 times higher in women (OR=2.77, 95% CI=1.86-4.14) compared to 60~64 years old. Socioeconomic factors (area of residence, education level, household income), including cohabitation Status (living alone VS living with other family members), and health behaviors (high-risk drinking, smoking, aerobic exercise) did not significantly effect on anemia. In addition, other than protein intake for men, nutrient intake did not have a significant effect on the prevalence rate of anemia. Hypertension, diabetes, and cancer significantly increased the risk of anemia. In Korea, the influencing factors of elderly anemia change over time, so periodic follow-up studies are needed.

The labor environment in Korea has changed and problems related to employment types are treated as important issues. Especially, the ratio of irregular workers has not only increased relatively, but the labor conditions in Korea also have worsened in the current years. Studies have reported an association between temporary workers and the prevalence of diseases. However, there is insufficient research on chronic disease and employment types. Methods: The current study examines the prevalence rate of diseases and health behavior by categorizing employment types among Korean adults. Data were obtained from the 2016-2018 Korea National Health and Nutrition Examination Survey. Totally, the data of 2,366 workers (1,239 regular and 1,127 irregular) were analyzed in the study. The types of employment were classified by a questionnaire querying about working conditions. The results showed that irregular workers earned less than regular workers and had a significantly higher prevalence of diabetes mellitus and hypertension. We propose that if discrimination related to working conditions were relieved, irregular workers would be able to invest more time to exercise and doing check-ups regularly. In addition, individual nutrition consultations considering the knowledge and personal environmental factors of each individual are necessary for the improved health of all workers.

Objectives: The purpose of this study was to evaluate the predictors of metabolic syndrome among police officers and determine its prevalence. Methods: Data were collected through a questionnaire survey and medical examination among 1,089 male police officers from 2010 to 2013. Information about age, marital status, smoking, drinking and exercise were based on data from the self-administered questionnaire. We collected job type, working position, and work duration from company personnel data and the indices of metabolic syndrome through the medical examination. Metabolic syndrome was assessed according to the NCEP-ATP III definition and the Asia-Pacific obesity guidelines. Results: The prevalence of metabolic syndrome among the 1,089 police officers was 33.4%. The prevalence of metabolic influencing factors were 47.5% for abdominal obesity, 30.1% for hypertension, 37.1% for hypertriglyceridemia, 22.0% for low HDL-cholesteralemia and 13.2% for hyperglycemia. Factors such as age, drinking, and family history were significantly associated with metabolic syndrome. Conclusions: Weight control and a moderate drinking program may decrease the prevalence of metabolic syndrome among male police officers.

The purposes of this study were to identify the degree of postprandial blood pressure reduction and the prevalence of postprandial hypotension by 3 different mealtimes of elderly people diagnosed with hypertension in nursing homes. After the informed and written consent, a total of 187 elderly people were recruited in the study. Systolic BP, diastolic BP were measured with ambulatory BP monitor every 15 minutes interval from 30 minutes before a meal until 120 minutes after each meal. The maximum SBP reduction was significantly bigger at breakfast than lunchtime or dinnertime. Among 187 elders, 137(73.4%) showed PPH at breakfast, 103(54.2%) at lunchtime, and 96(50.2%) at dinnertime. The most prevalent time point of PPH was 90 minutes after the initiation of a meal in all of 3 mealtimes. Among 8 measurement times, the prevalence of PPH was significantly higher in breakfast (3.0±2.7 times) than both lunchtime (2.1±2.5 times) and dinnertime (1.9±2.4 times). Although the occurrence of PPH by every mealtime should be taken into account in caring for the elderly, postprandial BP measurements need more attention after breakfast. Nurses should develop appropriate nursing interventions that can prevent postprandial blood pressure reduction in elderly people with hypertension.

The purpose of this study was to investigate the prevalence and differences of risk factors of Metabolic syndrome according to menopausal status. From the database of the 5th Korea National Health and Nutrition Examination Survey (KNHANES V) conducted in 2012, data of 3,537 women who responded to health interview and health examination questionnaires. The presence of Metabolic syndrome was assessed using the International Diabetes Federation (IDF) criteria. The prevalence of Metabolic syndrome was 17.3% in premenopause and 54.3% in postmenopause. BMI, waist circumference, blood pressure, total cholesterol, LDL cholesterol, triglyceride, and Ferritin were higher in postmenopausal women compared to premenopausal women. However, postmenopausal women had lower HDL cholesterol and TIBC when compared to premenopausal women. Hypertension was the most prominent characteristic of postmenopausal women. Low HDL cholesterol showed up as a meaningful factor in premenopausal women. According to multiple regression analysis, waist circumference, fasting glucose, and HDL cholesterol were independent predictors of menopause. Therefore, obesity control and blood lipids management is recommended for postmenopausal women.

Objectives: The purpose of this study was to investigate the effects of oral health behaviors of patients with hypertension and diabetic patients on the number of remaining teeth in Korean adults over 45 years of age, furthermore, we also aimed to develop oral health care programs and health promotion for patients with hypertension and diabetes. Methods: Altogether, 1,526 subjects with hypertension and diabetes from the 6th Korean National Health and Nutrition Survey (2013-2015) were analyzed. Results: A multiple logistic regression analysis was performed to determine the effects of oral health behavior and periodontal disease on residual teeth in patients with hypertension and diabetes after adjusting for age. We found 1.53 times the risk of having less than 20 remaining teeth in the group of brushing more than 3 times a day (95% CI: 1.00,2.35, p<0.001), 2.27 times (95% CI: 1.23-4.17, p<0.05) in the group not using the dental floss group 0.05), compared to the group undergoing regular dental check-up (95% CI: 0.93-1.85, p>0.05), compared to the non-smoking group 0.77 times (95% CI: 0.51-1.14, p>0.05), 1.33 times (95% CI: 0.98-1.80, p>0.05) in the drinking group compared to the non-drinking group, in the periodontal disease group, the risk of having less than 20 remaining teeth was 2.19 times higher (95% CI: 1.48-3.24, p>0.001) than in the normal group. Conclusions: As a super-aging society, develops in Korea, the prevalence of hypertension and diabetes will increase gradually. Therefore, an oral health policy should be implemented at the national level for the prevention and treatment of periodontal disease as well as the management of oral health the elderly.

The prevalence of obesity in Korean children is estimated to be around 10%, and has increased significantly over the past 20 years. Metabolic syndrome, which includes central obesity, glucose intolerance, insulin resistance, dyslipidemia, and hypertension, is a well documented risk factor for cardiovascular diseases, but there is no general consensus concerning its definition for children. In this study, ablut 30-40% of overweight or obese children had metabolic syndrome compared to less than 10% in the general population. Dyslipidemia was the most common component and hyperglycemia was the least common component of metabolic syndrome. If the prevalence of childhood obesity continues to increase, it is highly likely that the prevalence of the metabolic syndrome will also increase. These findings emphasize the importance of preventing obesity in addition to the diagnosis and management of metabolic syndrome in Korean adolescents.
