Abstract
PDF - This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam Province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: 38.9~44.6%%, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.l%), injury and poisoning(7.l%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.

Abstract

- OBJECTIONS: Cotinine, the major metabolite of nicotine, is a useful marker of exposure to tobacco smoke and self-reporting of smoking status is thought not to be reliable. This study aimed to evaluate the agreement between the smoking self-report among adolescents and the urinary cotinine test. METHODS: The study subjects were 1226 middle and high school students in Hanam city, who were selected by stratified random sampling. The self-report about smoking behavior was compared with urine cotinine value measured with PBM AccuSignRfi Nicotine (Princeton BioMeditech Corporation, USA). The percentage agreement, kappa and 95% confidence interval (CI) were calculated. RESULTS: The overall percentage agreement was 88.6%, and those for boys, girls, middle school, general school and vocational school students were 87.3%, 90.1%, 93.7%, 85, 5%, 90.7%, and 78.4%, respectively. The overall kappa index was 0.46 (95% CI=0.39-0.54) for overall, and those for boys, girls, middle school, general school and vocational school students were 0.56 (95% CI=0.48-0.65), 0.20 (95% CI=0.07-0.32), 0.21 (95% CI=0.09-0.34), 0.55 (95% CI=0.47-0.64), 0.42 (95% CI=0.33-0.52), and 0.48 (95% CI=0.36-0.60), respectively. CONCLUSION: The percentage agreement was relatively high but the kappa values very low for girls, and middle school students. Though the prevalence bias can be influenced by these results, the selfreport was not a sufficient tool for the evaluation of adolescents' smoking status, especially in girls or middle school students.
