This study was carried out to estimate the relationship between dietary intake, blood level, and urinary excretion of minerals and blood pressure in 30 healthy adults living in rural area of Korea(12 males and 18 females). Analysis for the nutritional status of the subjects were performed by 3-day dietary intake record, duplicated diet collection, 24-hour urine collection, and venous blood sampling before measuring blood pressure. The mean blood pressure of subjects was 117.50/80.83mmHg in males and 110.00/73.89mmHg in females. The mean daily intakes of Na, K, Ca, P, Mg, Fe, Cu, Zn estimated for 3 days were 199.97mEq, 49.56mEq, 452.50mg, 725.57mg, 240.40mg, 12.48mg, 3.41mg, 8.28mg, respectively. The serum concentration of Na, K, Ca, P, Mg, Fe, Cu, Zn were 139.83mEq/dl, 4.06mEq/dl, 8.86mg/dl, 3.28mg/dl, 2.13mg/dl, 0.12mg/dl, 0.12mg/dl, 0.14mg/dl, respectively. The 24-hour urinary excretions of Na, K, Ca, p, Mg, Fe, Cu, Zn estimated for 169.60mEq, 39.37mEq, 80.40mg, 398.97mg, 64.77mg, 0.21mg, 0.07mg, 0.29mg, respectively. No significant correlation was found between dietary intake, serum concentration, and urinary excretion of minerals and blood pressure. But, the serum Ca/Mg ratio showed negative correlation with the systolic and diastolic blood pressure at the level of significance of 5%. The study verifies the need for more systematic studies on interrelationship among minerals and mineral requirements in normotensive and hypertensive subjects.

Purpose: This study was conducted to estimate the relationship between health behavior and follow-up needed for results of health examinations. Methods: The participants were 2,245 adults over age 19. Data from the National Health and Nutritional Examination Survey VI-1 was used. Health behavior was defined as smoking, alcohol consumption, physical activity, hours of sleep and BMI. Those who needed follow-up care after a health examination were defined as having abnormal blood pressure, abnormal blood sugar, or abnormal blood cholesterol. Results: The proportion needing follow-up was 77.4%. The odds ratio (95%CI) for needing follow-up for blood pressure for men was 1.59 (1.18-2.15) with excessive alcohol consumption over one month, and 2.33 (1.73-3.13) with obesity, and for women, 3.55 (2.66-4.74) with obesity. For blood sugar in men it was 1.59 (1.18-2.15) with excessive alcohol consumption and 2.33 (1.73-3.13) with obesity, and for women, 3.55 (2.66-4.74) with obesity. For low HDL-C in men it was 0.53 (00.40-0.72) with excessive alcohol consumption and 2.39 (1.81-3.15) with obesity, and in women, 0.73 (0.57-0.94) with excessive alcohol consumption and 1.66 (1.29-2.14) with obesity. For high triglycerides it was 2.37 (1.42-2.39) with smoking and 2.34 (1.70-3.22) with obesity in men and in women, 1.51 (1.05-2.16) with obesity. Conclusions: The results of this study indicate that obesity is associated with high blood pressure, high blood sugar, low HDL-C, and high triglycerides.

Limited epidemiologic data is available regarding the cardiovascular effects of mercury exposure. The purpose of this study was to determine the relationship between mercury exposure from fish consumption and cardiovascular disease in a nationally representative sample of Korean adults using the Fourth Korea National Health and Nutrition Examination Survey (KNHANES IV 2008~2009). Survey logistic regression models accounting for the complex sampling were used to estimate the odds ratios (OR) adjusted for fish consumption frequency, age, education, individual annual income, household annual income, body mass index (BMI), waist circumference (WC), alcohol consumption status, and smoking status. The mean blood mercury level in the population was $5.44{\mu}g/L$. Trends toward increased blood mercury levels were seen for increased education level (P=0.0011), BMI (P<0.0001), WC (P<0.0001), and fish (i.e., anchovy) consumption frequency (P=0.0007). The unadjusted OR for hypertension in the highest blood mercury quartile was 1.450 [95% confidential interval (CI): 1.106~1.901] times higher than that of the lowest quartile. The fish consumption-adjusted OR for hypertension in the highest blood mercury quartile was 1.550 (95% CI: 1.131~2.123) times higher than that of the lowest quartile, and the OR for myocardial infarction or angina in the highest blood mercury quartile was 3.334 (95% CI: 1.338~8.308) times higher than that of the lowest quartile. No associations were observed between blood mercury levels and stroke. These findings suggest that mercury in the blood may be associated with an increased risk of hypertension and myocardial infarction or angina in the general Korean population.

This study was designed to investigate the relationship between the nutrient intakes, antioxidants, and inflammatory markers of overweight and obese adults (46 females and 16 males) in Yeongdong area. The study was conducted through questionnaires, anthropometric checkups, 2-day 24 hr recalls and blood biomarker analyses. Body fat was significantly higher in women compared to men. Diastolic blood pressure (DBP) and systolic blood pressure (SBP) were significantly higher in men compared to women. There were no significant differences in height, weight, body mass index, and waist size among the two groups. The intake of nutrients was significantly higher in men compared to women. Ferric reducing ability plasma (FRAP) was significantly higher in men compared to women. Body fat was positively associated with blood IL-6 and IL-8 levels. DBP was positively associated with FRAP. The intake of protein was negatively associated with IL-6 levels. The intake of carbohydrates was negatively associated with total antioxidant capacity (TAC). Prostaglandin E2 (PGE2) levels were negatively associated with TAC. These results suggest that antioxidant and inflammatory markers may be related to the body fat percentage and dietary intake in overweight and obese adults.

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.

Objectives: Blood lead and hyperhomocysteinemia have been found to be associated with cardiovascular disease. The objective of the present study was to assess the relationship of lead biomarkers on plasma homocysteine and blood pressure. Methods: To evaluate the effect of lead biomarkers including blood lead on plasma homocysteine and blood pressure in retired lead workers, 66 retired lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 42 controls were recruited from same area of retired lead workers with consideration of demographic characteristics. Results: The mean levels of blood lead and ZPP of retired lead workers were significantly higher than control group. There were positive significant correlations between blood lead and plasma homocysteine, also systolic and diastolic blood pressure. The multiple linear regression analysis also reveled that plasma homocysteine was significantly associated with blood lead after adjusting for age, gender, body mass index, lead exposure, smoking and drinking. Diastolic blood pressure was significantly associated with blood lead, plasma homocysteine, and total cholesterol; whereas, systolic blood pressure was significantly associated with plasma homocysteine only. Conclusions: Blood lead showed significant association with plasma homocysteine and blood pressure even after more than mean 10 years from their retirements.

This study was designed obtain and early detection the workers exposed to excessive copper dust and also to present biological exposure index. The exposed group consisted of 62 male workers at the metallurgy workplaces. To evaluate the degree of individual exposure the copper dust, each personal air sampling was collected. Biological exposures in the exposed group was quantified for the blood and urine copper levels using flameless atomic absorption spectrophotometer. The control group consisted of 70 male adults with the history of nonexposure to copper by the inhalation occupationally. The average concentration of copper in blood and urine of the exposed group was $49.44{\pm}8.90(29.05-80.63){\mu}g/dl$, $39.99{\pm}11.04(29.62-80.63){\mu}g/l$ respectively. The average concentration of air borne copper was $0.48{\pm}0.31(0.03-1.18)mg/m^3$. The average concentration of blood and urine copper in the control group was $42.93{\pm}5.84(25.05-57.85){\mu}g/dl$, $33.02{\pm}13.38(12.00-82.05){\mu}g/l$ respectively. The difference observed in the average concentration of blood and urine copper of the exposed and control groups was statistically significant seperately (blood copper, p<0.05 ; urine copper, p<0.05). The relationship between the individual exposure concentration of air borne copper and the concentration of the blood and urine copper was statistically significant, respectively (blood copper, r=0.54, p<0.05 ; urine copper, r=0.37, p<0.05). The relationship between the working duration and the concentration of blood and urine was not statistically significant respectively (blood copper, r=0.14 ; urine copper, r=0.12). The relationship between the age and the concentration of blood and urine copper was statistically not significant respectively (blood copper, r=013 ; urine copper, r=-0.06). The relationship between blood and urine copper concentration in the exposed group was statistically significant (r=0.62, p<0.05), and the relationship between blood and urine copper concentration in the control group was also statistically significant (r=0.39, p<0.05).

Background: Obesity and dental caries have common risk factors such as food intake, eating habits, and lifestyle. Nevertheless, there has been no consensus on the significant association between obesity and dental caries, and additional studies are needed. We investigated the relationship between obesity and dental caries in some college students in this pilot study. Methods: Forty-two obese college students (body mass index [BMI]≥25) registered at a University Obesity Clinic and 19 normal students (18.5≤BMI<25) were recruited. Oral examinations were conducted, and anthropometric data and blood samples were collected. The blood concentrations of low-density lipoprotein (LDL), high-density lipoprotein, and triglyceride were also measured. After controlling for dental plaque index, a univariate analysis of dental caries indicators related to obesity was performed; partial correlation analysis was also conducted. A nonparametric test was used for the analysis of gender-related trends due to the limited number of participants. Results: The obese group had significantly fewer missing teeth (p=0.014), missing surfaces (p=0.035), filled surfaces (p=0.038), and decayed-missing-filled surfaces (p=0.020) than the normal group. There was no difference between the males in the normal and obese groups. The females in the obese group had significantly fewer missing teeth (p=0.003), missing surfaces (p=0.003), and decayed-missing-filled surfaces (p=0.046). Partial correlation analysis showed a weak negative correlation (r=-0.256) between the blood LDL concentration and decayed-missing-filled teeth. The other obesity and dental caries indicators were not correlated. Conclusion:The blood cholesterol concentration had a negative relationship with dental caries, and there were fewer cases of dental caries in the obese group in this study. However, it is important to clarify the relationship between obesity and dental caries through a dietary survey or additional investigations considering other confounding factors.
