Abstract PDF: PURPOSE: This study was conducted to assess the level of agreement among survey instruments used to study dementia and to determine the prevalence rate of suspected dementia using different instruments. SUBJECTS AND METHODS: A total 171 subjects older than 65 in Gyeongju-si, Gyeongsangbuk-do, were surveyed from February to October 2003. The age, sex and educational level were examined through interview surveys, and cognitive function was evaluated using three survey instruments including MMSE-K, S-SDQ, and KDSQ. RESULTS: The cognitive function scores obtained with the MMSE-K showed significant difference according to age. For sex and educational level significant differences were observed with all three survey instruments. The kappa index, the level of agreement between the questionnaires, was 0.302 between MMSE-K and S-SDQ, 0.401 between MMSE-K and KDSQ, and 0.762 between KDSQ and S-SDQ. The prevalence rate of suspected dementia based on the criteria suggested by MMSE-K, S-SDQ, and KDSQ was 27.5%, 15.2%, and 17.0% respectively. CONCLUSION: The results of this study suggest that caution is needed when comparing the measured cognitive function scores and analyzing the prevalence of dementia; this is because the prevalence of dementia and cognitive functions vary according to the questionnaires used.

OBJECTIVES
The purpose of this investigation was to study the health status of apartment guards and associated factors. MATERIALS AND METHODS: This investigation was conducted for 1 month starting from August, 1997. Study population in this cross-sectional survey consisted of 182 guards of apartments located throughout the district of Taegu. Each subject completed a questionnaire about his general characteristics, health behaviors, job descriptions, subjective GIT symptoms and somatization and depression using Symptom Checklist-90-Reversion (SCL-90-R) by self administrated questionnaire and personal interview). RESULTS: Study subjects had one or more GIT symptoms(53.3%), somatization symptoms(83.5%) and depression symptoms(79.7%). The mean scores of GIT, somatization and depression symptoms were not different among the age groups and based on marital status, respectively, but, significantly different by education level(p<0.05). The mean scores of GIT, somatization and depression symptoms were not different among the age groups and hased on marital status, respectively, but, significantly different by regular diet and by the subject's health status(p<0.05). The mean scores of GIT, somatization and depression symptoms were not different by duration of shift work, by job tenure and by the number of managed houses but, those of somatization and depression symptoms were significantly different by level of job satisfaction(p<0.05). CONCLUSION: The health statuses of guards at apartments were different from other shift workers because of health worker effects and characteristics of their jobs.

Abstract PDF

A cross-sectional study was performed to evaluate the effects of chronic exposure to low-dose solvent on neurobehavioral performance of 48 male workers exposed to organic solvents. A control group of 50 workers was selected from same factories. Each worker completed a medical and occupational questionnaire and four tests of Neurobehavioral Core Test Battery. These included Benton visual retention test, digit symbol, digit span, and pursuit aiming. Comparison of mean performance showed a significantly poorer performance on digit symbol, digit span, and pursuit aiming. In univariate analysis, age contributed to poor performance on Benton visual retention test and educational level was found to reduce the performance on symbol digit in both groups. Amount of alcohol intake was found to reduce the performance on digit symbol and smoking appeared to slow pursuit aiming in the exposure group. In multiple regression analysis, controlling for age, educational level, alcohol, and smoking, solvent exposure was found to be associated with performance of digit span, and number of correct dot of pursuit aiming. Age on Benton visual retention, educational level on digit symbol, and smoking on pursuit aiming were found to be a significant factors on each test items. This study suggest that short-term memory, and perception can be affected easily by chronic exposure of organic solvents which air concentration level were under the Threshold Limit Value.
