Purpose: This study was to investigate the relationship between blood pressure, lipids and body mass index by smoking status among adolescents. Methods: This study was designed as a descriptive correlational study. General and smoking characteristics were collected using a questionnaire. The smoking group consisted of 42 (33%) students and the non smoking group 85 (67%) students. Blood pressure, lipids, height and weight were measured, and body mass index was calculated to $kg/m^2$. The collected data was analyzed by the n(%), ${\chi}^2-test$, t-test and Pearson correlation coefficient (SPSS 12.0). Results: 1. The smoking level was different between grade, smoking status among the family, the contentment of their relationship with their parents, school life and teachers. 2. The smoking group's systolic blood pressure, total cholesterol, triglyceride, low density lipoprotein cholesterol and body mass index were higher than those of the non smoking group. 3. The smoking amount had a significant positive correlation between total cholesterol and low density lipoprotein cholesterol. Conclusion: The result of this study offered basic data to develop intervention programs to prevent hypertension and hyperlipidemia in smoking adolescents.

This study was carried out on 178 bus drivers in the Masan area to investigate their health and nutritional status. THe nutritional status of the subjects was surveyed using a self-administered questionnaire, and blood analyses were conducted through annual health examinations in June, 1999. The results were as fellows: About 51% were classified as normal, 33% as health-concerned, and 17% as disease-suspected. The levels of total seam cholesterol were significantly higher in the over 20 year group (194.64 $\pm$ 41.42 mg/dl) than in the under 10 year group (175,00 $\pm$ 31.33 mg/dl) with respect to the length of their driving careers. Systolic blood pressure (SBP) was significantly higher in the 51 to 60 age group than in the other groups (p < 0.05) . The total seam cholesterol increased with increasing age (p < 0.001), and SBP increased with increasing Body Mass Index (BMI) (p < 0.001). Diastolic blood pressure (DBP), total cholesterol (p < 0.01), hemoglobin (p < 0.05) and glutamate-pyruvate-aminotransferase (GPT) (p < 0.05) were significantly higher in the BMI of over 20, than in the BMI under 20. The GPT was significantly higher in the BMI over 25 than in the BMI under 25. In The mean daily energy intake was 1912.7 kcal (76.5% of the RDA) ultra the protein intake was 74.3 g (106.2% or the RDA). Compared with the recommended allowance, the energy, calcium, thiamin, and riboflavin intakes were below, and the Fe, vitamin A, vitamin C intakes were above the Korean RDA. The average carbohydrate, protein, fat ratio of energy intake was 66 : 15 : 19, respectively. The length of their driving careers had a positive correlation with their ages and total serum cholesterol levels, and their ages had a positive correlation with their blood pressures, total seam cholesterol and hemoglobin levels and BMI. Their BMI had a positive correlation with their ages, blood pressures, total serum cholesterol, hemoglobin, GPT and GOT levels. The results of this study indicate that bus drivers needed regular exercise, and control of their body weights to prevent chronic diseases, and that their health status should be monitored as the length of their driving careers and ages increase.

The purpose of this article is to analyze the conceptual change of nine 11th graders after implementing the model-based instruction of blood circulation by multidimensional framework, and to find some implications about teaching strategies for improving conceptual understanding. The model-based instruction consisted of 4 periods: (1) introduction for inducing students' interests using an episode in the science history of blood circulation, (2) vivisectional experiment on rats, (3) visual-linguistic model instruction using the videotape of heartbeat, and (4) modeling activity on the path of blood flow. Based on the data from pre-test, post-test and interviews, we classified students' models on the path of blood flow, and investigated their ontological features and the conceptual status of blood circulation. Most students could describe the path of blood flow and the changes of substances in blood precisely after the instructions. However, the modeling activity were not sufficient to improve students' understanding of the mechanisms of the blood distribution throughout various organs and the material exchanges between blood and tissues. From the interview of 9 students, we acquired informative results about conceptual status elements that were helpful to, preventing from, or not used for students' understanding. It was also found that conceptual status of students depended on the ontological categories into which students' conceptions of blood circulation fell. The results of this study can help design the effective teaching strategy for the understanding of concept of the equilibrium category.

Background: We investigated the risk of cancer mortality according to obesity status and metabolic health status using sampled cohort data from the National Health Insurance system. Materials and Methods: Data on body mass index and fasting blood glucose in the sampled cohort database (n=363,881) were used to estimate risk of cancer mortality. Data were analyzed using a Cox proportional hazard model (Model 1 was adjusted for age, sex, systolic blood pressure, diastolic blood pressure, total cholesterol level and urinary protein; Model 2 was adjusted for Model 1 plus smoking status, alcohol intake and physical activity). Results: According to the obesity status, the mean hazard ratios were 0.82 [95% confidence interval (CI), 0.75-0.89] and 0.79 (95% CI, 0.72-0.85) for the overweight and obese groups, respectively, compared with the normal weight group. According to the metabolic health status, the mean hazard ratio was 1.26 (95% CI, 1.14-1.40) for the metabolically unhealthy group compared with the metabolically healthy group. The interaction between obesity status and metabolic health status on the risk of cancer mortality was not statistically significant (p=0.31). Conclusions: We found that the risk of cancer mortality decreased according to the obesity status and increased according to the metabolic health status. Given the rise in the rate of metabolic dysfunction, the mortality from cancer is also likely to rise. Treatment strategies targeting metabolic dysfunction may lead to reductions in the risk of death from cancer.

The purpose of this study was to compare health status and diery health practice of middle-aged rural adults with or without hypertension. Eighty three subjects (mean age : 55.6$\pm$11.9), were composed of 22 males and 61 females. Data collection includes serum and urine collections for health status and the questionnaire including dietary habit of salt, sugar, dietary fiber and fat intake for dietary health practice The results were as follows : The subjects were composed 23 persons of under 55 year-old group and 19 persons of over 65 year-old group. Of the 83 subjects, 28.9% were recognized hypertension and 33.7% were measured hypertension by systolic blood pressure. In the aspects of dietary health practice, hypertension group showed that smoking and weight control practice and were significantly low score, alcohol and dietary fiber intake were high score. Hypertension group showed higher frequency in diabetes mellitus and lower in gastrointestinal complain and liver disease. than normal blood pressure group. Serum, TG, bilirubin, BUN and cholesterol, were significantly higher in hypertension than normal blood pressure group. The mean values of serum albumin and urinary creatinine excretion in hypertension group werw significantly lower. The consciousness of health status was lower in hypertension group and also attributed to worse personal feeling health by modified CMI test.

An increasing number of women are becoming victims of their smoking habits. Cigarette smoking is implicated as a major cause or several chronic diseases. This study was performed to investigate the nutritional status associated with smoking and other factors like drinking or fruit and vegetable consumption frequency in Korean adult women. The 2001 Korean National Health and Nutrition Survey provided the current adult women sample (n = 2900), who were categorized as smoking (n= 141) and nonsmoking group (n = 2759). The smoking women declared significantly lower intakes of carbohydrate, calcium and vitamin C and higher alcohol than nonsmokers, but with nonsignificant difference of BMI. The smoking and drinking group showed the lowest intakes in most of the nutrients, the lowest BMI and significantly elevated blood pressure. The smoking group with fruit and vegetable consumption frequency less than 3 times a day also showed lower intakes of most of the nutrients and significantly higher systolic blood pressure. Less proportion of smokers perceived their health status very good or good and more smokers felt depressed often. In conclusion it seems cigarette smoking is associated with the decreased nutrient intakes in adults women. When smoking is connected with other unhealthy dietary habits like drinking or lower fruit and vegetable consumption, it may exacerbate the nutritional status and cause elevated blood pressure.

To assess the nutritional and health status of the elderly, anthropometric measurements and blood test for analyzing biochemical indices were carried out from August to September in 1996. Data on the incidence of a specific disease and clinical symptoms were also collected by interviews with a questionnaire. Among the total of 169 free-living elderly interviewed(91 men, 78 women), 86 elderly(57 men, 29 women) participated in the anthropometric measurements, and 73 elderly(52 men, 21 women) in blood tests. Average heights and weights were much lower than the standards established in the Korean Recommended Dietary Allowances. While average triceps skinfold thickness of men and women were above the 50 percentile of the reference data, mid-arm muscle circumferences were lower than the 50 percentile. Prevalences of anemia, assessed by hemoglobin using WHO definition, were 38.5% for men and 33.3% for women. Blood levels of total protein and albumin were above the normal limit for all participants. Mean blood cholesterol levels of men and women were 163.9mg/dl and 185.8mg/dl, and triglyceride levels were 138.2mg/dl and 161.9mg/dl, respectively. Women older than 75 years generally had high levels of BMI, total cholesterol and triglyceride. Health status assessed by clinical symptoms generally showed no significant difference by age, and their smoking, and drinking habits. Males and the elderly who exercised regularly had better health status. It was suggested that exercise was a good way to improve health status. (Korean J Community Nutrition 2(4) : 568-577, 1997)

This study was out to evaluate the folate nutritional status of Korean pregnant women and to investigate the relationship between serum folate levels of maternal-umbilical cord blood and pregnancy outcomes. Folate intakes of the pregnants was estimated by dietary folate intakes obtained from semiquantitative frequency questionnaire and supplementary folate intakes. The serum folate levels in both maternal blood and umbilical cord of 29 pregnant women at delivery and 13 nonpregnant controls were measured by redioimmunoassay. The total folate intakes(dietary and supplementary)of the pregnant women was 465. 4$\mu\textrm{g}$/d which was 93% of the Korean RDA for folate. Maternal mean serum folate levels of the pregnants was 6.1$\mu\textrm{g}$/ml, significantly lower than that of nonpregnant women(8.9ng/ml). Mean serumfolate level of umbilical cord blood was 14.2ng/ml, which was 2.3 folds higher than that of maternal blood. This finding indicates that the uptake of folate in the fetus may be due to an active placental transport mechanism. Maternal serum folate level correlated positively with that of umbilical cord blood, showing that folate concentration of umbilical cord blood is affected by maternal status. There was no significant correlation between the serum folate levels in maternal-umbilical cord blood and the pregnancy outcomes.(Korean J Nutrition 33(8) : 840-847, 2000)

This study investigated the effects of vitamin C supplementation on immune status in smoking and nonsmoking male college students. Blood samples were obtained from 15 healthy smoking and from 15 healthy nonsmoking volunteers before and 4 weeks after vitamin C supplementation (1000mg/day). Daily nutrient intakes was also calculated. Plasma vitamin C, E, and A concentrations, white blood cells and subpopulations, lymphocytes and subpopulations, NK cell percentage,plasma immunoglobulin A, G, M and complement C3, plasma interleukin-2 , and prostagladin E2 were measured . Daily vitamin C consumption was lower in smokers than in nonsmokers. Vitamin C supplementation significantly increased plasma vitamin C in smokers, and increased NK cell percentage in smokers and nonsmokers. Plasma IL-2 concentrations were significantly increased by vitamin C supplementation in nonsmokers, and decreased helpe $r^pressor T cell ratio were decreased by vitamin C supplementatiion , but the differences were not significant. White blood cells and subpopulation percentage and plasma prostaglandin E2 concentration were not affected by smoking and vitamin C supplementation. These findings as nonsmokers.rs.

PURPOSE: This study examined the specific clinical risk factors in middle-aged men with age-related loss of skeletal muscle mass (ALSMM). METHODS: The present research analyzed the data from a cross-sectional study of 1,564 community-dwelling participants aged between 40 to 49 years old. The participants were screened for ALSMM. The study examined various risk factors, including age, height, weight, body mass index, waist circumference, skeletal muscle mass index, smoking and drinking status, systolic and diastolic blood pressure, fasting glucose levels, and triglyceride and cholesterol levels. RESULTS: The risk factors of ALSMM were height, body mass index, waist circumference, skeletal muscle mass index, systolic blood pressure, diastolic blood pressure, drinking status, fasting glucose, and triglyceride levels (p < .05). The weight, triglyceride, and smoking status variables were non-significant (p > .05). CONCLUSION: The risk factors for ALSMM among community-dwelling adults were determined. These results are expected to contribute to the existing literature on ALSMM and provide potential risk factors associated with the development of ALSMM in middle-aged males.
