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.

BACKGROUND: For gastric cancer, primary prevention by risk factor modification might have some important roles. However, previous studies having investigated the factors associated with stomach cancer reported various results. In addition, there were only a few studies based on Korean population. METHODS: A case control study was carried out on 106 cases matched for age and sex with 106 controls in a tertiary care hospital. In patients who were aged 75 years or less and had been newly diagnosed as adenocarcinoma of stomach between July 1996 and January 1997 were included into the case group. Information on baseline characteristics, health habits, dietary habits of study subjects was obtained through an interview using structured questionnaire. Conditional logistic regression analysis was used to evaluate the factors associated with stomach cancer. RESULTS: Salt preference was associated with significantly increased risk of stomach cancer (odds ratio[OR]=9.81, 95% confidence interval[CI]=2.28 42.2). Eating broiled food more than three times a week significantly increased the risk of stomach cancer (OR=3.33, 95% CI=1.16 9.55) compared to eating it less than once a week. Blood type, family history of stomach cancer, smoking, and alcohol consumption were not associated with stomach cancer. CONCLUSION: Salt preference and frequent eating of broiled food are the risk factors significantly associated with stomach cancer in this study subjects.

In an effort to evaluate the effectiveness of teaching behaviors and to compare the qualitative and quantitative methods of evaluating clinical preceptors, we performed a study with questionnaires to survey students and preceptors who participated in preceptorship in our department of Family Medicine over 6 months from May, 1991 to September, 1991. Students reported humanistic orientation behaviors to be most contributing to their clinical medical education. However, preceptors favored student centered instructional strategies. An analysis and comparison of the qualitative and quantitative evaluation of preceptors suggest that qualitative approach identifies individual preceptor strengths and weaknesses more clearly than quantitative approach and may be more useful for providing feedback to stimulate and guide change.

BACKGROUND: Importance of the participation of clinical practitioners in the development of guideline is increasingly emphasized. We studied the attitude of family physicians to the guideline for hypertension management and compared it with their reported practice patterns. METHODS:We developed a guideline for hypertension management with reference to other guidelines previously published and used by WHO and health organizations in many countries. A questionnaires asking attitude to the contents of the guideline and real practice pattern was sent to 200 Korean family physicians. Response rate to the questionnaire was 27.5%. RESULTS: The agreement rate to annual blood screening in persons aged 15 and older was 87%, while the reported practice rate in most of patients was only 42%. The agreement rates to medical history taking in hypertensives were high in all items, but reported practice rate was very low. The agreement rates to physical examination in hypertensives were relatively high in all items, while reported practice rate was high only in lung and heart examination. The reported practice rate of laboratory tests were less than 60% and that of electrolyte check was only 22%. Most of the study subjects agreed with all behavior modification methods. Although 80% of the subjects agreed that diuretics or beta blocker should be used as an initial regimen, the reported practice rate was only 36 %. CONCLUSION: There observed a big difference between attitude to the guideline and reported practice pattern in this study. It showed the need to narrow the gap between them.
