The objectives of this study were to determine the relationship between lifestyle-implementation and metabolic syndrome in an electronics research and development company, and to provide a foundation for health providers of health management programs for setting priorities. METHODS: From July 1 to July 16, 2008 we carried out a descriptive cross-sectional survey. Consecutive workers of one R & D company in Seoul, Korea (N=2,079) were enrolled in study. A checklist for lifestyle (from the National Health Insurance Corporation) consisted of questions regarding diet, drinking, smoking and exercise. After the survey, researchers obtained data from health profiles for metabolic syndrome(waist-circumference, triglycerides, HDL cholesterol, blood pressure and fasting blood sugar level). Lifestyle was recorded as good or not good. Statistical analysis of metabolic syndrome and the lifestyle of subjects was done using multiple logistic regression analysis. RESULTS: The prevalence of metabolic syndrome in our study gropu was 13.3% (N=277). After adjustment for age, the adjusted odds ratios (odds ratio, 95% confidence intervals) for metabolic syndrome increased in proportion to the number of bad habits: two (1.72, 1.23-2.44), three (2.47, 1.73-3.56), and four (3.63, 2.03-6.34). Relative to subjects eating both vegetables and meat', the OR for 'meat' eaters was 1.66 (1.18-2.31). Compared with 'non-smokers and ever-smoker', the OR for 'current-smoker' was 1.62 (1.25-2.10). Compared with 'Healthy drinker', the OR for 'unhealthy drinker' was 1.38 (1.05-1.83). CONCLUSIONS: Poor lifestyle was associated with an increased likelihood of metabolic syndrome. These findings suggest that lifestyle-based occupational health interventions for young employees should include a specific diet, smoking cessation, and healthy-drinking programs.

AbstractAbstract PDF
An increase in the serum gammaglutamyltransferase (GGT) concentration has been regarded as a marker of alcohol drinking or liver disease. Some reports, however, have suggested that the serum GGT may be a sensitive and early biomarker for the development of prediabetes and diabetes. In this study we investigated whether serum GGT is a reliable predictor of the incident impaired fasting glucose (IFG), including diabetes. METHODS: We performed a prospective study for two years (2002-2004). We analyzed the periodic health examination data from a total of 4,711 men. The examinations were done in the years 2002 and 2004. The analyzed data included a self-questionnaire, a physical examination and the laboratory results. Both IFG and diabetes were defined as a serum fasting glucose concentration of more than 100 mg/dL and 126 mg/dL, respectively. RESULTS: A total of 738 cases (15.7%) of incident IFG and 13 cases (0.3%) of diabetes occurred. The mean serum GGT concentrations were quite different between the normal (38.0 IU) and incident IFG groups (50.3 IU), and the incident diabetes group (66.0 IU) (p <0.001). After multivariable adjustment, the relative risks for incident IFG or diabetes across the baseline GGT categories (<10th, 10th-20th, 30th-40th, 50th-60th, 70th-80th and >90th percentile) were 1.0, 1.172 (0.769-1.785), 1.107 (0.725- 1.689), 1.444 (0.934-2.232), 2.061 (1.401-3.031) and 2.545 (1.784-3.631) (p-value for trend: <0.001). The risks significantly increased with increasing levels of GGT for 2 years; when comparing the increased groups (<10%, 10- 20%, >20%) versus the decreased over 20% group of GGT, the risks for IFG or diabetes were 1.334 (1.002-1.776), 1.613 (1.183-2.199) and 1.399 (1.092-1.794). CONCLUSIONS: Our findings suggest that serum GGT concentrations within its normal range may be an early predictor of the development of IFG and diabetes. As serum GGT is a relatively inexpensive test and a reliable marker, it might have important implications in public health promotion.

AbstractAbstract PDF
This study was performed to determine the incidence density and the prevalence of sero-positive hepatitis C from 1999 to 2002 among adults aged 20 and over residing in Seoul and the Gyeonggi province. METHOD: The data for period was obtained from 114, 635 adults, residing in Seoul or the Gyeonggi province, who had undertaken comprehensive health screening tests from Jan 1999 to Dec 2002 in a University hospital in Seoul. Among them, subjects with sero-negative status against hepatitis C were selected (21, 408 in 1999, 28, 830 in 2000) and then followed up until Dec 2002 to determine the incidence of hepatitis C during this period. The serum was tested with the immunoradiometric assay (IRMA) which uses third generation HCV antibody. Age adjusted rates were estimated by direct standardization using a reference population of 2000 aged from 20 to 80 years. RESULTS: The prevalence of anti-HCV from 1999 to 2002 was 2.1 per 1000 persons (95% CI 1.8~2.4). Male showed 1.7 per 1000 persons (95% CI 1.4~2.1), while female showed 2.7 per 1000 persons (95% CI 2.2~3.2). Age?sex adjusted rate showed 2.8 per 1000 persons (95% CI 2.64~2.96), which is lower than the results of some previous study. The prevalence showed a significantly increasing pattern with age both in males and females (p< 0.05). The incidence density of anti-HCV among the population aged 20 and over was 1.1 per 104 person-years at risk (95% CI 0.6~2.4) ; 1.2 (95% CI 0.6~2.7) for males and 0.8 (95% CI 0.6~4.2) for females. Age adjusted incidence density was 2.91 per 104 person-years at risk (95% CI 2.43~3.38) for those aged 20 and over. It showed an increasing pattern with age (p< 0.05), especially for those age over 50 years. CONCLUSION: The study subjects for this study were supposedly healthier than the general population so the prevalence and incidence for the general population are thought to be higher than the results of the present study.

AbstractAbstract PDF
Hemoglobin(Hb), zinc protoporphyrin(ZPP) and blood lead(PbB) levels were determined for 1,851 blood samples collected from healthy urban population to establish reliable baselines for Hb, ZPP and PbB levels by age and sex. ZPP values were analyzed with a Hmatofluorometer and PbB determinations were concurrently carried out using flameless atomic absorption spectrophotometry. The blood sampling period was about 6 months from May, 1991 and the summarized results were as follows; 1. The mean value of Hb in male female were 14.55+/-1.81 g/dl and 12.61+/-1.81 g/dl respectively and there was statistically significant difference(p<0.05). 2. The mean value of ZPP in pre-schoolchildren was 37.49+/-13.31 microgram/dl for male, 35.77+/-11.85 microgram/dl for female and that of ZPP in after 7 years groups was 31.91+/-8.23 microgram/dl for male, 30.11+/-9.11 microgram/dl for female and there was statistically significant difference(p<0.05). 3. The mean value of PbB in pre-schoolchildren was 25.10+/-5.21 microgram/dl for male, 24.45+/-4.18 microgram/dl for female and that of PbB in after 7 years groups was 24.28+/-3.00 microgram/dl for male, 21.99+/-5.05 microgram/dl for female and there was statistically significant difference(p<0.05).
