Abstract
Although the etiology of colorectal adenoma is not yet clear, numerous epidemiologic studies of colorectal adenoma(precursors of cancer) have shown a positive association with obesity and an inverse association with physical activity. The difference of the possible association of colorectal adenoma with body mass index(BMI= wt(kg)/ht2(m2) and physical activity(kcal/day) according to anatomic sites and gender was investigated in this case-control study. Between July 1994 and october 1998, 345 cases of patients(male 181, female 164) with pathologically confirmed incident colorectal adenoma and 1655 control subjects(male 598, female 1,057) were collected from Our Lady of Mercy Hospital, The Catholic University of Korea. After colonoscopy, self-reported weight and height, together with measures of intensity and time of exercise and lifetime job activity was obtained by the interviewers. Site- and gender-specific odds ratios relative to the lowest tertile of BMI and physical activity were determined using unconditional logistic regression after adjusting for potential confounders. Compared with subjects in the lowest terile of body mass index, multivariate-adjusted odds ratio of right colon for male and female in highest tertile were 1.49(95% CI:0.74-3.01) and 1.96(95% CI:0.93-4.15), respectively. Compared with subjects in the lowest tertile of physical activity, multivariate-adjusted odds ratio of right colon for male and female in highest tertile were 0.66(95% CI:0.35-1.26) and 0.83(95% CI:0.50-1.39), respectively. These results support a positive association between body mass index and occurrence or progression of adenoma in left colon and physical activity is associated with an elevated risk of right colon.

Abstract
BACKGROUND
Because of their large size and excellent computerized records of illness and services rendered, the importance of national insurance program is getting much attentions from the public health researchers and the national and local health authorities. In reality, however, most health records from medical insurance program suffer very much from inaccurate disease coding, and therefore, they are practically in no use.
METHODS
Pattern of incorrect disease coding of 6 Notifiable Acute Communicable Diseases that believed not to have been occurred in Korea lately was reviewed. The reasons of such incorrect codings in different level of medical institutions were studied. This study also attempted to see how an official intervention asking the medical institutions to correct their coding behavior works by comparing the frequencies of incorrect disease coding before and after the intervention.
RESULTS
Study results showed that more incorrect disease codings came from clinics than hospitals, and non-physician personnel in clinics and hospitals seemed to be responsible for most of the incorrect disease codings. Most frequent diseases coded incorrectly such as cholera and poliomyelitis were the ones that physicians and non-physician personnel in the clinics and hospitals had been familiar with for a long time period.
CONCLUSION
Even a simple official intervention asking the clinics and hospitals to correct their coding behavior was very effective : total number of incorrect disease codings before intervention (398 cases from 144 institutions) dramatically decreased (14 cases from 8 institutions) after intervention. Significant decrease in incorrect disease coding was found more in small institutions such as clinics and public health facilities than large institutions.
