The use of self reported height and weight is very common in epidemiologic studies and clinical settings. In this study we assessed the accuracy of selfreported weight, height and body mass index by comparing with measured data. Data were obtained from 1065 persons(657 men, 358 women) who visited a health care center for routine medical check-up during the period September 1994-February 1995. The correlation between reported and measured height and weight was very strong. There were some discrepancies between two data, however, and men and women differ ed somewhat in their pattern of misreporting. Weight was overestimated by 0.27kg in men and underestimated by 0.09kg in wo men whereas height was overestimated in men(0.88cm) and women(2.15cm). These misreported data resulted in an underestimation of body mass index and low sensitivity for diagnosing overweight in men and women. The size of error was larger in women than in men. So it suggests that the self reported height and weight data could be used as a continuous variable with little error, but misclassification could be occured when the self reported data were used as a categorical variable. Errors in self reported weight and height, BMI were related to a person's over-weight status. The more people overweighed the more they underestimated their weight. Educational level and age, exercise, marri age had no relationship with the accuracy of self reported data. In conclusion, the use of self reported weight and height in epidemiologic studies and clinical settings could result underestimation of obesity, especially in obese female group.

PURPOSE: To evaluate the effects of case management using Resident Assessment Instrument-Home Care (RAI-HC) in home health service for older people. METHODS: All elders were assessed at baseline and 3 months later using RAI-HC. The change of function in the intervention group was compared with that of a conventional intervention group. Function was measured with Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Cognitive Performance Scale (CPS), Depression Rating Scale (DRS), Pain and the number of Clinical Assessment Protocols (CAP). RESULTS: Among ninety two elders participated in the program, 59 were allocated to the case management group and 33 to the conventional group. The intervention, home health service by a nurse over a 3 month period, consisted of comprehensive assessment, case conference for care plan, direct care, education and referral, and outcome evaluation. The percent of elders whose function improved in the intervention group was greater than the conventional group for depression (odds ratio [OR]: 10.941, confidence interval [CI]: 2.338-51.206), IADL (OR: 4.423, CI: 1.151-16.999) and the number of CAP (OR: 11.443, CI: 3.805-34.410). CONCLUSION: Case management was effective for older people in the community. The effect might have resulted from individual, systematic intervention, however, standards of service including eligibility criteria for case management and collaboration of multi-disciplines is required for more effective home health service programs.

BACKGROUND: Frailty is a wasting syndrome that presents loss of physiological function by aging, lowering of reserve capacity, and disability of body system. It is currently being considered an important issue in geriatrics. This study examined frailty level of Korean elderly in community and whether frailty can be meaningful a predictive factor for functional disability. METHODS: Demographic characteristics, the number of chronic diseases and medications, cardiovascular health study (CHS) frailty index, study of osteoporotic fractures (SOF) frailty index, activities of daily living, Instrumental activities of daily living, depression, mini-mental state examination (MMSE) and fall history were examined for 302 men and women over 65 years old who visited the three community seniors welfare centers from February 2008 to June 2008. RESULTS: There were definite differences of frailty status by age, educational level, marital status, monthly income, body mass index, the number of chronic diseases, the number of medications, depression, MMSE and fall history (P < 0.05), except in gender (P < 0.432). In logistic regression analysis for functional disability with frailty status defined by SOF frailty index, odds ratio to dependency of instrumental activities of daily living (IADL) from the healthy to the prefrail stage increased 6.84 times while from the healthy to the frail stage increased 130.87 times. These effects still increased after covariate adjustment. Also, the CHS frailty index showed the same result although there was some difference in odds ratio. CONCLUSION: There were meaningful correlations of frailty with functional disability when dividing Korean elderly's frailty levels into the healthy, the prefrail and the frail stages.

BACKGROUND: Frailty is considered to be a clinical syndrome characterized by decreased physiological reserves associated with a greater risk of health-related problems, hospitalization, and death. The current study examined hospitalization, falls, cognitive decline and disability between robust, prefrail and frail elderly in one year. METHODS: 110 participants aged 65 or more who visited two senior welfare centers in Seoul from February 2008 to June 2008 were surveyed again from March 2009 to June 2009 with demographic characteristics, number of chronic diseases and medication, study of osteoporotic fractures (SOF) frailty index, instrumental activity of daily living (IADL), depression, mini-mental state examination-Korean version (MMSE-K), falling history and admission history within one year. These results were compared with participants' previous survey done one year ago. RESULTS: Among total 110 subjects, 48 (44%) robust, 30 (27%) prefrail, and 32 (29%) frail subjects changed to 26 (24%), 54 (49%), and 30 (27%) respectively over the year. There were statistical significances in age, number of chronic disease, depressive mood, MMSE, falls, hospitalization, IADL disability contributing to frailty (P < 0.05). Frailty defined by SOF frailty index was associated with greater risk of adverse outcomes. Frail subjects had a higher age-adjusted risk of cognitive function decline (odds ratio [OR], 3.57), disability (OR, 9.64), fall (OR, 5.42), and hospitalization (OR, 4.45; P < 0.005). CONCLUSION: The frailty index like SOF frailty index might predict risk of falls, disability, hospitalization, and cognitive decline in the elderly, emphasizing special attention to the individuals showing frailty in outpatient examination.

BACKGROUND: Due to rapidly growing elderly population, there are increasing numbers of older persons with multiple chronic disorders and geriatric problems arising from polypharmacy. In this study we tried to find out the state of polypharmacy and inappropriate drug prescription and their related factors in community-dwelling elderly by review of drugs taken by older persons visiting a day health center. METHODS: From April 2007 to July 2007, 80 subjects of 65 year-old or over with chronic illness who visited a elderly-wellness and health care center were randomly sampled. All of them were surveyed by structured questionnaires, medical records review, pill counts about all medications they are taking and experience of adverse drug reactions. And all the prescribed medications were reviewed or their drug prescription's appropriateness for each elderly according to Beers criteria. Data results were evaluated by frequency and correlation analyses. RESULTS: The average counts of drugs taken by elderly with chronic disorders were 7.23, minimum 1 to maximum 27 drugs a day. Patients experienced more adverse effects significantly when more prescribed medications were taken (P=0.005), and patients with lack of information about their drugs had taken increased number of medications (P<0.001). Referred to Beers criteria, inappropriate cases of prescription were observed in 26 persons. Those drugs were NSAIDs including aspirin in 17 subjects (21%), amitrityline in 3 (4%), short-acting benzodiazepines in 3 (4%), long acting benzodiazepines in 2 (3%), and anticholinergic antihistamine in 1 (1%). CONCLUSION: Polypharmacy is very common in community-dwelling elderly with chronic disorders. More medications were related to more adverse drug reactions and lack of information about their drugs related to increased number of drug taking. High proportion of inappropriate drug prescriptions was observed in the elderly, which may have resulted from poor education concerning geriatric care of the medical personnels.

BACKGROUND: Since 1998, mass urinary screening tests have been conducted in Korean school children. We analyzed the urinary screening test data gathered from the metropolitan city, Seoul, to identify the prevalence of persistent urine abnormalities. METHODS: The students were tested for hematuria and/or proteinuria using dipstick urinalysis. If the results were positive, the students were asked to visit a medical clinic to recheck urinalysis and in report their results. RESULTS: Among 1,337,210 students, who were screened with initial urinalysis, 10,871 students (proteinuria, 3,626 (0.27%); hematuria, 7,634 (0.57%); both, 389) were recommended to undergo second urinalysis in which 8,819 students (81.1%) did. Among them, 851 had persistent proteinuria and 2,618 had persistent hematuria. The results of the first urinalysis were scored based on the severity of hematuria and proteinuria from +1 to +4. Among all students 24.7% of the students who scored +1 and 40.4% who scored +3 proteinuria on the first test had persistent proteinuria, and 56.4% with both proteinuria and hematuria had persistent proteinuria on the second test. For hematuria, the more positive in the first test showed more prevalence of persistent hematuria. And 61.6% of students with both proteinuria and hematuia had persistent hematuria on the second test. CONCLUSION: The presence of both hematuria and proteinuria seemed to be a powerful predictor for persistent abnormal urine finding. And the more positive response in the first test was related to persistent abnormal finding. Therefore we should follow up closely for those students with positive findings.

BACKGROUND: Inpatient smoking cessation programs have been known to be quite effective for smoking cessation, but it was rarely conducted among Koreans. This study was to investigate the effect of inpatient smoking cessation program among Korean smokers. METHODS: From March 1 to April 30, 2008, we carried out a randomized controlled trial for inpatient smoking cessation program among 70 smokers who were 18 years of age or over and admitted to a university hospital in Seoul, Korea. For the intervention group, a trained doctor conducted the systematic educational program for smoking cessation of 30 minutes to an hour. For the control group, they were advised with a 3-minute explanation for smoking cessation. We assessed the abstinence rates of study participants at 1 week, 1 month, and 3 months after discharge. RESULTS: In 3 months after the discharge, the abstinence rate for the intervention group was 37.1% while that of the control group was 14.3%. In simple logistic regression analysis, the smokers among the intervention group were 3.5 times more likely to abstain than those in the control group. After controlling for confounding factors, the smokers among the intervention group was 11.4 times more likely to abstain than those in the control group. CONCLUSION: For Korean smokers, the inpatient smoking cessation program showed a higher success rate of abstinence compared to simple advice and limited counselling.

OBJECTIVES: Korea faces a number of challenges to meet demands in the area of geriatric professional medicine in a country with a rapidly ageing population. We evaluated the satisfaction and feasibility of the current education certification for geriatric physicians. METHODS: Geriatric physicians who were deemed qualified by the Korean Geriatrics Society during the period of 2001 to 2005 (n=2,200) were asked to complete structured questionnaires sent to them by mail about their satisfaction of and need for certificates of education, as well as their opinions on their geriatric specialty training. A total of 419 physicians responded. Descriptive analysis and hierarchical regression were performed to rate the respondents.satisfaction, the characteristics of the need for clarity and utility in education certification, and the characteristics of their patients. RESULTS: Although most respondents were satisfied with their education certification, those who had more elderly patients, aged 65 or older, and those who had more cognitively impaired patients, rated their education as significantly lower than did other physicians. Both groups expressed the need for more the comprehensive care and assessment concerning of their education. Multiple regression analysis indicated that satisfaction with geriatric physician qualification was associated with a physician's age, specialty, and percentage of elderly patients. CONCLSIONS: This study suggests that the current system of education certification is limited in terms of feasibility and physician satisfaction.

BACKGROUND: The prevalence of hypertension reaches 29% in adults over 30 years of age in the Korean population; however, the control rate is merely 44%. The aim of this study was to investigate the associated factors for target blood pressure achievement after triple combination therapy in hypertensive patients. METHODS: From February 2016 to May 2018, 10 family physicians recruited 348 patients, who newly started a triple combination antihypertensive medication. Target blood pressure was defined as a systolic blood pressure (SBP) <140 mmHg and diastolic blood pressure (DBP) <90 mmHg after 6 months of triple combination therapy. Multivariate logistic regression analyses were performed to analyze the associated factors for target blood pressure achievement. RESULTS: Among the 348 study participants, 317 completed 6 months of treatment. The target achievement rate was 76.3% (242/317). The mean absolute difference and 95% confidence interval (CI) for the SBP and DBP were 10.8 mmHg (8.8 to 12.7) and 6.4 mmHg (5.1 to 7.8), respectively (P<0.05). The odds ratio (OR) for the target blood pressure achievement increased in those with college education or higher (OR, 2.69; 95% CI, 1.22–5.92), those with dyslipidemia (OR, 1.74; 95% CI, 1.01–2.99), and those who were satisfied with the medication (OR, 29.91; 95% CI, 3.70–241.92). CONCLUSIONS The presence of dyslipidemia and patient's satisfaction with the medication were associated with target blood pressure achievement in our analyses. Our findings suggest the importance of patient's factor in the control of blood pressure.
