Abstract
PDF - The objectives of this study are to estimate the prevalence of diabetes mellitus(DM) and to identify risk factors associated with fasting blood sugar in a rural adult population. We carried out a cross-sectional study on the residents over 30-year old. Among the 1077 eligible subjects, 725 persons responded to the study; the study consisted of interview on family and past history of DM, anthropometry, blood pressure, and blood sugar level in each subjects. Only 707 subjects of 725 participants had fasting blood sugar(FBS) examined and the rest, 18 subjects were had casual blood sugar examined due to failure of fasting over 8-hour. When subjects had FBS >or= 140mg/dl, 2 hours postprandial blood sugar level was checked after 75g oral glucose loading. The prevalence of DM was 8.9%, and age standardized prevalence rate adjusted to Korean population of 1995 was 5.8%. Mean and SD of fasting blood sugar in men was 99.8 +/- 22.6, and in women was 111.5 +/- 29.9. Mean levels of fasting blood sugar were significantly higher in women than in man and as their ages advanced the prevalencies in creased in both sexes. PP2 blood sugar levels were significantly higher in elder age and in persons with higher FBS levels than others. The risk factors associated with FBS were past history of diabetes, sex, socioeconomic status and waist-to-hip circumference ratio; the risk of diabetes was increased in female, people with past DM history, central obesity and low socioeconomic state. The low socioeconomic status associated with DM in this study, which is different from other study results, should be pursued in further studies.

- This study was conducted to analyzed blood lipid profile and other risk factors among crew members who are currently active and had more than 10 years of experience as crew members. Data was analyzed using medical record files in an airline medical department. The results are as follows. 1. The total number of crew members studied was 392. Among age groups, those below age 40 consisted of 26(6.9% of the total), those in age 41~50 were 135(34.4%) and those over age 51 were 230(58.7%). 263 were former air force pilots consisting 66.9%. Those who had captain status numbered 211 comprising 53.7% of the total. The type of aircraft most of the crew members involved were large size aircraft which totaled 268(68.2%). With respect to the number of working years as crew members, 488(48.9%) comprised the largest group with 11~15 years. 2. The rate of smoking among crew members has shown gradual decrease with 50.3% smoking in 1983 to 33.6% in 1993. Among 41~50 age group the rate has shown a decrease from 20.9% to 13.3%. In those group over age 51 it decreased from 25.5% to 16.6%. But group below age 40 were within the range of 3.6~3.8% with no significant change in the rate of smoking. 3. Body Mass Index in age group over 51 was slightly higher than other age groups. On the whole, BMI over 25 was not found. 4. The total cholesterol levels of those below age 40 were 196.9+/-38.5 mg/dl, 216.2+/-39.2 mg/dl in ages 41~50, and 225.1+/-42.5 mg/dl in age group over 51. No significant difference was found among age groups. 5. HDL-cholesterol levels of over age 50 were higher than other age group and ranged from 40~55 mg/dl. 6. LDL-cholesterol levels of those over 51 were 126.7+/-37.7 mg/dl higher than other age groups. But there were no significant changes in all age during 10 years of follow up. 7. Cardiac index of age group below age 40 was 3.8, 4.3 in age group 41~50 and 4.5 in those over age 51 group. No significant changes among groups were found during the follow up period. 8. Triglyceride levels of age group below age 40 was 142.2+/-70.1, 167.3+/-77.5 in age group of 41~50 and 173.6+/-89.7 in age group over 50 showing that triglyceride levels increased with age. No significant changes in pattern were noted.

Abstract
PDF
- This study was attempted to observe leisure time physical activity pattern and its relationship to coronary risk factors(BMI, systolic blood pressure, diastolic blood pressure, serum total cholesterol, triglycerides, fasting blood sugar). Subjects participated in this study were 277 adult male workers of an industry in Kyungpook province, Korea. Energy expenditure were measured using modified Physical Activity History questionnaire of CARDIA study by interviewing. Serum total cholesterol, triglycerides and blood sugar level were tested with 5 ml fasting blood and height, weight and blood pressure were measured. Data on smoking and drinking habits and others were obtained. Geometric mean of leisure time physical energy expenditure were estimated as 212.80 kcal per week for study subjects and only 22.4% of them expended 2,000 kcal or more per week in leisure time physical activity. Taking walks or hikes and jogging or running were more frequent leisure time physical activities in study subjects. Statistically significant mean differences in total weekly leisure time physical activity for all coronary risk factors were not found among three groups. Because energy expenditure of leisure time was generally low in this subjects and most of them were healthy men, we did not found that leisure time physical activity was significantly associated with coronary risk factors.
