This study was carried out to compare the bone mineral density and risk factors of osteoporosis between normal and rheumatoid arthritis in postmenopausal women. Sixty-eight postmenopausal patients with rheumatoid arthritis(RA) were compared with 124 postmenopausal normal women. Data were collected from october, 1998 to April, 1999 at Dong-a university hospital in Pusan. From all subjects, individual characteristics such as age, body weight, height, age of menarche, duration of menopause, gravity, parity, and breast feeding period and factors of life style such as milk consumption, exercise, alcohol intake, cigarette smoking, coffee consumption were identified as influencing factors of osteoporosis by questionnaire. From RA patients, health assessment score, Ritchie articular index, erythrocyte sedimentation rate, C-reactive protein and steroid dosage were measured by rheumatologist on measuring bone mineral density. Bone mineral density was measured at the Lumbar spine, femoral neck, femur Ward's triangle, and femur trochanter using dual x-ray absorptiometry. The data was analyzed by using a frequency, t-test, Chi-square, ANCOVA with SPSS PC program. The results could be summarized as follows : 1) There was a significant difference in age and breast feeding period between RA patients and normal women. 2) RA patients took less calcium in the past and practiced less regular exercise in past and present than normal women. 3) There was no difference in lumbar bone mineral density between RA patients and normal women. 4) There was a significant difference in femur Ward's triangle and femur trochanter between RA patients and normal women after adjustment for age and breast feeding period. 5) The prevalence of osteoporosis of all subjects was the highest in femur Ward's triangle. In summary, our findings suggest that the bone mineral densities of femur Ward's triangle and trochanter in postmenopausal women with RA is significantly lower than normal women. Also the exercise participation rate of postmenopausal women with RA is lower than normal women. For the further study, we recommend to develop exercise program that improve the bone mineral density in femur Ward's triangle and trochanter and to test the effect of that exercise program.

Benzidine Industry in Korea has started after Japan has banned its production in early 1970's, and it has been in operation in Korea for over 20 years. However, it is not known yet whether any bladder cancer has developed from benzidine exposure. This study was done to screen benzidine-exposed workers for bladder cancer, and to examine the feasibility of employing screening test at the workplace. All the workplaces that manufacture or use benzidine for more than 20 years in Korea have been covered in this study, and they include 2 benzidine manufacturing factories, 5 benzidine using factories, as well as 2 benzidine free factories as an outside control. In total, 516 workers were screened with urine stick test and urine cytology test for the evidence of hematuria and abnormal urothelial cells. Each worker was also asked about risk factors and symptoms of bladder cancer including past medical history, smoking, medication and occupational history Benzidine in the air was measured by personal and area sampling. Out of 516 screened workers, 84(16.3%) workers showed positive hematuria in urine stick test, and 7(1.4%) workers showed degenerative cells in urine cytology tests. Those workers with abnormal urine test results who have been exposed to benzidine fo more than 10 years were further screened, and, in total, 23 workers were examined with intra-venous pyelography and cystoscopy. None of those screened had any evidence of bladder cancer When workers with only past hematuria history were included in the positive hematuria group, 96(18.5%) had positive hematuria. On the multiple logistic regression analysis, positive hematuria was significantly associated with benzidine exposure, history of other occupations with elevated bladder cancer risk, pyuria and glycosuria. The association got stronger as direct benzidine exposure was accounted through individual task analysis, and as exposure duration was accounted with tenure analysis. For those with benzidine exposure with more than 10 years of tenure, the odds of having positive hematuria was elevated 2.14(95%C.I is 1.08 to 4.25) times more than for those without exposure. Even though bladder cancer was not detected for several limitations including short observation period, majority of studied workers with short latency, healthy worker effect, and low sensitivity of single screening test in a cross-sectional study, the study results suggest that hematuria screening is a feasible and very useful test for bladder cancer screening among benzidine exposed workers.

Although Traditional Korean Medicine had always referred to Mamok(痲木: Paresthesia) as the prodrome of stroke for a long time, yet there were only few research papers on it. Hence, the purpose of this research is to explore the relationship between Mamok(痲木; Paresthesia) as the prodrome and an attack of stroke. Setting 509 Korean impatient women as the subject of research, 264 of the whole are stroke patients and 245 are non-stroke patients. Blood tests, questionnaires, and body measurements (height, weight, waist, hip) are performed to the subjects. Basic population traits, life-style, and past history are included in the contents of questionnaires. whether or not they have experience the numbness, description about the clinical characteristics of the symptom, the body parts which the symptom occurred, the onset of the symptom, and the incidences are examined in the category inquiring the numbness of the hand and foot. After adjusting for age, unilateral numbness was associated with significantly increased risk of stroke. When adjusted for other factors(Half of WHR, History of Hypertension and Diabetes mellitus, Cigarette smoking, Alcohol drinking, Education, Marital status, Regular exercise), the risk of stroke was positively associated with unilateral numbness.(Age Adjusted Odds Ratios=2.282(95%CI=1.107-4.705), Multivariate Odds Ratios=4.105(95% CI=1.233-13.671)) Whereas no significant association was observed in the onset and the incidence of unilateral numbness. This study suggest that preceding Mamok(痲木; paresthesia) before stroke attack is may be common prodrome symptoms of stroke. Prospective cohort study on the association between Mamok(痲木;Paresthesia) as the prodrome and an attack of stroke in Korean population will be necessary.

Purpose: The purpose of this study was to describe the sexual behavior, health risk related to reproductive health, and characteristics of sexual experience among college students in Korea. Methods: Six thousands college students were selected through proportional quota sampling based on region, college, and gender. Structured questionnaires were used for data collection. Descriptive statistics and chi-square test were used to describe the data. Results: Thirty eight percent (N=2,285) of the participants reported sexual intercourse. The mean age of first time sexual intercourse was 19.3 years old. Respondents reported the following health risks such as smoking, drinking, not exercising, no regular meal patterns, chronic disease status, and weight loss over 10 kg in the past three months showed significant differences by sexual intercourse experience (p<.01). Among those who had sexual intercourse experiences, 7.1% of them reported having a history of STDs and 11.6% reported a pregnancy or pregnancy of one's partner. Conclusion: The findings of this study reflect the current trends of sex behaviors among college students and correlations between health risks related to reproductive health and sexual intercourse experiences. Developing reproductive health education programs based on the findings and providing the programs to college students through a school nurse is suggested.

Purpose: The purpose of the study was to investigate the health status(present illness, ADL and IADL), health perception, and health promotion behaviors of low-income elderly who are receiving the visiting nurse service in the community. Method: The sample of the study was 735 elderly over 65years old with basic livelihood security, who were conveniently selected from 245 public health centers nation-wide. Data collection was done using a structured questionnaire through interviews by visiting nurses. Result: The average number of present illnesses in the study subjects was 4.18. The average scores of ADL and IADL were 15.903.39and 9.772.97 respectively, which indicates a relatively independent everyday life. However, $64.2\%$ of the subjects perceived their health status as 'not healthy'. In terms of health promotion behaviors, $77.8\%$ of the subjects had ceased smoking, $83.9\%$ stopped drinking, $56.4\%$ had a regular diet, $45.8\%$ received regular physical check-ups during the past two years, and $66\%$ received flu shots. Approximately $50\%$ of the subjects were practicing 3-4 health promotion behaviors. Significant factors associated with health promotion behaviors were ADL, IADL and self-efficacy. Conclusion: Health promotion programs which focus on regular diet, exercise, and regular physical check-ups should be developed to improve independence of everyday life and quality of life among low-income elderly.

Purpose: This study was performed to identify the prevalence of menstrual disorders in Korean women based on body mass index (BMI) and lifestyle factors, by utilizing the Korean National Health Insurance Database. Methods: A retrospective observational study design was used for the secondary data analysis. Data of women aged 15 to 49 years who were diagnosed with menstrual disorders were extracted from The National Health Insurance Service-National Health Screening Cohort in Korea from 2009 to 2016. The age-standardized prevalence rate of menstrual disorders was calculated using SAS version 9.4, and a Chi-square test and Cochran-Armitage test were performed. Results: In total, 2,219,445 cases were extracted from the database. The prevalence of menstrual disorders significantly increased from 8.6% to 11.6% (Z=135.16, p for trend <.001) over the past eight years. In particular, it was higher in underweight women than in women with normal weight across all years (Z=-4.18~-14.72, p<.001). Moreover, statistically significant differences in the prevalence of menstrual disorders were found to be associated with drinking and smoking in all years and with physical activity levels in part (p<.05~.001). Conclusion: These findings present compelling evidence on the prevalence of menstrual disorders based on a national database. Since the prevalence of menstrual disorders has steadily increased and differs based on BMI and lifestyle factors, educational and clinical interventions are necessary to promote risk awareness and appropriate behavioral changes among Korean women.

Background: Adolescence is the transitional period between childhood and adulthood. We have to pay attention to their psycho-social problems as well as their physical symptoms. In this context, we need to investigate the adolescent depression tendency and its related factors. Method : From May to June in 1008, we chose one elementary school, one middle school and one high school in Seoul and surveyed for all students who were above the 4th grade of elementary school and their parents. We analyzed the data for 3,685 students. Result: From the 6th grade of elementary school to the 1st grade of high school, the girls' DSRS(Depression self-rating scale) score was significantly higher than the boys'. The DSRS score was increased from the 2nd grade of high school for boys and from the 1st grade of high school for girls. The Pearson correlation coefficient between age and DSRS score was 0.16(p<0.01) and that between APGAR and DSRS score was -0.45(p<0.01). The median number of psychosomatic symptoms of the past month was 6, and when students complained for more psychosomatic symptoms, the DSRS scores were higher. Those who drank or smoked ranked significantly higher in DSRS score; and, those who exercised regularly, had leisure activity, and had a faithful person for counselling ranked significantly lower in DSRS score. Conclusion : Adolescents who complained of many psychosomatic symptoms needed to be screened for depression. A primary physician have to intervene about health related behavior such as family function, smoking, exercise and relieving stress.

This study investigated the symptoms, medical and occupational history of 424 workers of 5 reactive dye Industries in the Inchon area in Korea. The study was performed on March 6 and July 19, 1989. The tests applied to the subjects were : serum total IgE, specific IgE, skin prick test with 7 inhalatory antigens, pulmonary function test, chest X-ray, methacholine test, and bronchoprovocation test. The workers were classified according to these tests into 4 groups (healthy, realtively healthy, need careful medical observation, and occupational asthma), and were compared in terms of the group characteristics and the symptom prevalence. The prevalece of occupational asthma of workers in reactive dye was 5.9% Significant differences were observed among the 4 groups. The groups were significantly different in the variables of sex and duration of smoking among their general characteristics ; and dyspnea, wheezing, chest pain, cough, nasal symptoms and sore throat among symptoms ; asthma, bronchitis, and other respiratory diseases with respect to their past medical history. This study suggests that we should pay special attention to the workers exposed to the risk of occupational asthma.

Objectives: A community-based, cross-sectional survey was conducted to determine theprevalence of osteoporosis and to evaluate the effects of body composition, health behaviors and reproductive history on bone density in postmenopausal women. Methods: The study subjects were 362 postmenopausal women, aged 45 years old or over, who were invited to the hospital. Information on their socio-demographic characteristics and the potential risk factors such as their past medical history, smoking, alcohol intake, exercise, diet and menstrual/reproductive histories were collected by trained interviewers. Weight, height, the body mass index ($kg/m^{2}$), and body composition variables were measured. Bone mineral density of the lumbar spine was measured by dual energy X-ray absorptiometry (DXA). Results: The prevalence of osteoporosis was 30.6% in the $45{\sim}64$ years old women, 52.5% in the elderly women aged $65{\sim}74$, and 68.7% in the women aged 75 years or over. After adjustment for the effect of potential covariates, those women in the highest 25% (4th quartile) of the lean body mass are less likely to have osteoporosis (aOR=0.31, 95% CI=0.12-0.76), compared with the lowest quartile group. More parity also had significantly detrimental effects on osteoporosis. Conclusions: These findings suggest that the prevalence of osteoporosis in postmenopausal women increased with age from 46.3% of those aged 45-64 to 68.7% for those aged 75 and over. Lean body mass and parity appeared significant contributor to bone mineral density in postmenopausal women in this population.

Objectives: This study was conducted to analyze health behavior and utilization of university health clinics by college and university students. Methods: There are 376 colleges and universities in Korea as of May 2007. Of them 243 (69.6%) run health clinics in their campuses. Twenty of them were selected and 1,754 students were surveyed by using self reporting questionnaires. The data collected were analyzed by SPSS ver. 12.0. Results: Out of 1,754 students 56.5% were in good health. Of the subjects 15.6% were cigarette smokers, 30% were non drinkers, 20.8% exercise regularly, 53.7% sleep for seven to eight hours a day, 48% had proper body weight (BMI) 20-25) and 20% had physical examination in the past two years. The scores of health practices were higher in male students than female students (P 0.05). Perception rates of university clinics were higher in female students than male students. (P 0.01). Many students have intention to use the clinics (P 0.01). On health promotion program 35.2% of the subjects used clinics for emergency service, 32.8% participated in drinking control program, 32.8% in smoking cessation program, 20.4% in immunization program and 19.2% in regular health screening program. Conclusions: Comprehensive data for health behavior and need of health promotion services by the students should be collected regularly in order to meet the needs of students and faculty members in higher education institutes. The university authorities should pay more attention on the activities of health clinics in order to promote health of the students.
