This study was conducted to investigate instant coffee-mix intakes and its relations with anthropometric measurements, nutrient intake, and blood lipid in Gangneung and Samcheok residents. Coffee-mix is a mixture of instant coffee, sugar and coffee-creamer. It is a standardized convenience food in Korea. Recently, Koreans appear to consume too much of instant coffee-mix. The respondents of this study were 218 Koreans (Gangneung region 133, Samcheok region 85). The average age was 56.0 years (male), 57.5 years (female). They were divided into 2 groups, the instant coffee-mix drinkers and the non-drinkers. The nutrient intake and anthropometric measurements and their relations with coffee-mix intakes were analyzed (nutrient intakes were calculated by converting per 1,000 kcal and adjusted by age, region). As for male, body fat was significantly higher in coffee-mix drinkers (18.1 kg, 25.0%) than in non-drinkers (17.1 kg, 23.8%). In the case of females, serum triglyceride was significantly higher in coffee-mix drinkers (109.1 mg/dL) than in nondrinkers (102.9 mg/dL). Coffee-mix intakes and coffee-mix's contributions to energy were higher for participants from Samcheok (21.2 g, 4.7%) than those from Gangneung (16.6 g, 3.4%). In addition, for Samcheok, coffee-mix's contribution to energy was significantly higher in male (5.6%) than in female (4.2%). Coffee-mix intakes and energy contribution of coffee-mix were not significantly correlated with anthropometric measurements. Only HDL-cholestrol showed significantly negative correlation with coffee-mix's contributions to energy. Based on the above results, we conclude that usual instant coffee-mix intake may increase intakes of sugar and fat and exert negative effects on serum lipids. Therefore, it is needed to control too much instant coffee-mix intake in the dietary management of rural residents.

The purpose of this study was to examine the status of coffee intake in South Korea by analyzing the 4th Korea National Health and Nutrition Examination Survey. The results showed that 52.3% of Koreans consumed coffee at least once a day. Males consumed coffee more frequently than females and those aged 20-39 years and 40-59 years consumed coffee most frequently. Coffee drinkers consumed coffee two times a day and 138 mL each time on average. Coffee was mainly consumed either at home (44.8%) or in the workplace (36.1%); males drank coffee most frequently in the workplace and females did so at home. Milk coffee including coffee from vending machines and coffee mix (73.8%) was the most common type of coffee consumed. The results of this study would extend the understanding of the general status of coffee intake in South Korea, which has shown steady growth but remains a relatively overlooked research area.

The iron status and its relations with nutrient intake, coffee drinking, and cigarette smoking were evaluated through the blood analysis and 3-day dietary recalls in 102 apparently healthy Korean adults (48 males, 54 menstruating females) aged 20-49 years and living in Daejeon City. Mean values of hemoglobin (Hb) in males and females were 15.5g/dL and 13.2g/dL, mean corpscular hemoglobin concentration (MCHC) 36.0% and 36.8 %, serum iron (SI) 135 $\mu\textrm{g}$/dL and 97 $\mu\textrm{g}$/dL, transferrin saturation (TS) 39.4% and 29.2%, and serum ferritin (Ft) 88.1 $\mu\textrm{g}$/L and 23.4 $\mu\textrm{g}$/L, respectively. For males the prevalences of abnormal values of iron status indicators were 4.2% in Hb, 2.1% in TS, and 4.2% in Ft, and for females 16.7% in Hb, 25.9% in TS, and 35.2% in Ft. Among females 9.3% had abnormal Ft, TS, and Hb, which was considered as iron-defeciency anemia, and 14.8% had abnormal Ft and TS. As a whole, the impaired iron status prevalences were estimated to be 2.1 - 4.2% for males and 9.3 - 35.2% for females. Mean daily intakes of iron and heme-iron were 13.7mg and 1.51mg in males, and 12.3mg and 1.45mg in females. Ft was positively correlated with dietary energy, protein, iron, and vitamin A, Hb with energy and iron, and MCHC with iron and heme iron. Vitamin A also tended to show positive correlations with Hb, SI, and TS. Coffee drinkers taking 3 cups per day or more had higher levels of Hb, MCHC, and Ft in males and MCHC in females, compared to non-coffee drinkers. Higher levels of Hb and MCHC were found in male smokers than in non-smokers. Coffee drinkers took more energy and vitamin A in males and MPF protein in females than non-coffee drinkers. From the above results, it was suggested that the iron status of men was much better than that of women, and the intakes of energy, iron, heme iron, and especially vitamin A were positively associated with the iron status. Cigarette smoking elevated Hb and MCHC, but the effect of coffee drinking on iron staus was not clear. (J Community Nutrition 5(1) : 44∼50, 2003)

In India, among males, leukemia rates vary across the country. The present unmatched hospital-based case-control study conducted at Tata Memorial Hospital included subjects registered between the years 1997-99. There were 246 leukemia cases and 1,383 normal controls. Data on demographics, lifestyle, diet and occupation history were recorded. Cigarette (OR=2.1) and bidi smoking (OR=3.4) showed excess risk for leukemia. Odds ratios were 3.9 for fish-eaters, 0.40 for chilli eaters, 1.5 for milk drinkers and 0.60 for coffee drinkers, compared to non-drinkers/eaters. However, neither exposure to use of pesticides nor cotton dust showed any excess risk for leukemia.

Coffee has been known to have both beneficial and harmful effects upon health. Coffee is one of the most widely consumed beverages, worldwide. Dementia/Alzheimer's disease (AD) and cardiovascular disease (CVD) are public health problems that are rapidly increasing in the aging population. Due to the high consumption of coffee, even small effects on an individual's health could have a large effect on public health. The aim of this review article is to provide an overview of previously published studies of coffee consumption on health. Herein, we focus on epidemiological and experimental findings to investigate whether coffee-drinking habits, and/or the quantity of coffee consumption, have any relationship to CVD, dementia/AD, and other chronic diseases. Although the underlying mechanisms are not fully understood, when comparing coffee drinkers with non-drinkers, moderate doses of caffeine showed protective effects against CVD and AD. We hypothesized that caffeine may be a novel therapy to treat CVD and dementia/AD.

The elevation of plasma total homocysteine(tHcy) is now established as a risk factro for cardiovascular disease. It is also well known that plasma levels of folate and vitamin $B_{12}$ influences homocysteine metabolism as cofactors. Recently, the effects of health-related lifestyle factors, such as smoking, alcohol drinking coffee consumption, regular exercise, and etc, on plasma tHcy have been determined. The Hordalane Homocysteine Study revealed that smoking and coffee consumption are major deter minants of plasma tHcy as well as folate levels; however, the influence of alcohol intake is still controversial. In Koreans, the effects of lifestyle factors of plasma tHcy have not yet been determined. Thus, we investigated the relationships of various lifestyle determinants with plasma tHcy, folate, and vitamin $B_{12}$ levels and the erythrocyte folate concentrations in Korean adults (99 males and 96 fermales). Plasma tHcy levels were significantly hight in male subjects. On the contrary, plasma levels of folate and vitamin $B_{12}$ and erythrocyte folate concentration of the females were significantly higher than those of the males. Among the five lifestyle factors determined in the study, regular exercise significantly affects plasma tHcy levels only in the females, Contrary to the expectation, there were on significant differences in plasma tHcy levels between alcohol drinkers and non-alcohol drinkers as well as smokers and non-smokers. And also, plasma tHcy leverls were not different between coffee consumers and non-coffee consumer and between green tea consumers and non-green tea consumers. Although alcohol intake did not influence plasma tHcy levels, the duration, frequency, and amount of alcohol drinking showed significant negative relationships with plasma folate levers. These results indicate the regular exercise and alcohol intake might influence plasma levels of tHcy and folate in Koreans, although the results were not reveled in both sexes.

The purpose of this study was to investigate the relationship between frequency of coffee consumption, metabolic biomarkers, and nutrition intake in adult participants in the combined 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects (2,095 males and 3,297 females) were classified according to sex and frequency of coffee consumption (${\leq}1$ time/month, ${\geq}2$ times/month and ${\leq}6$ times/week, 1 time/day, 2 times/day, 3 times/day) using food frequency questionnaires. Nutrition intake was analyzed using 24 h recall data. The 3 times/day coffee consumption group had a significantly higher age, and frequency of smokers and drinkers compared to the ${\leq}1$ time/month coffee consumption group in both male and female participants. Males in the 3 times/day coffee consumption group had a significantly lower HDL-cholesterol level, but females had a higher waist circumference compared with the ${\leq}1$ time/month coffee consumption group. Males in the 3 times/day coffee consumption group had a significantly lower nutrient density of fiber, vitamin B2, vitamin C, calcium and phosphorus compared with the ${\leq}1$ time/month coffee intake group. Females in the 3 times/day coffee consumption group had a significantly higher nutrient density of fat and niacin, but lower nutrient density of carbohydrate, calcium, phosphorus, and iron compared with the ${\leq}1$ time/month coffee intake group. In males, the frequency of coffee consumption was not associated with the levels of metabolic biomarkers. In females, the frequency of coffee consumption was positively associated with diastolic blood pressure after adjustments for multiple confounding factors, including age, BMI, smoking status, alcohol consumption, physical activity and energy intake. Coffee consumption was associated with decreased diastolic blood pressure in females. These findings suggest the importance of an awareness of the association between coffee consumption and metabolic risk.

Lifestyle behaviors including dietary habits are well known to play key roles in bone metabolism. The purpose of this study was to investigate the relationship among the factors affecting bone mineral density (BMD) including age, anthropometric parameters, lifestyle behaviors, and dietary habits of men aged more than 50 years. Ninety-one men, who visited health promotion center at one of the university medical centers, were divided into two groups according to the BMD: normal and osteopenia. The BMD of femoral neck in the osteopenia group was significantly lower than that of the normal group ($0.77\;{\pm}\;0.28$ vs. $0.98\;{\pm}\;0.08\;g/cm^2$). The proportion of the regular exercisers was significantly lower in the osteopenia group than in the normal group (p = 0.027). In the osteopenia group, the femoral neck BMD was significantly decreased in smokers and coffee drinkers compared to no-smokers and no-coffee drinkers. The femoral neck BMD was increased among those who consume breakfast and beans and bean products more frequently and those with a greater meal regularity. In the normal group, the lumbar spine BMD was significantly increased among those with frequent consumption of beans and bean products. The lumbar spine BMD was significantly correlated with exercise (r = 0.263), and the femoral neck BMD with weight (r = 0.284), BMI (r = 0.324), relative body weight (r = 0.294), exercise (r = 0.269) and frequency of beans and bean products consumption (r = 0.216). These results indicate that lifestyle behaviors and dietary habits play important roles in maintaining optimum bone health in the middle-aged men.

Objectives: To examine the association between serum gamma-glutamyltransferase(GGT) activity level and blood pressure, serum lipids in the male residents of rural area, we analyzed cross-sectionally the data of 379 male health examinees aged 40 years and older from rural areas in Gyeongsangnam-do prefecture in Korea. Methods: Blood pressure and concentration of serum lipids were compared between high and low level of serum GGT activity by t-test or Wilcoxon rank sum test. Possible confounding effects of age, body mass index and coffee drinking were adjusted by analysis of covariance. Results: Adjusted values of systolic and diastolic blood pressure were higher in the group of high level of serum GGT activity in non-drinkers(P=0.055 and P=0.074 respectively) and drinkers(P=0.284 and P=0.398) of alcohol. Adjusted serum total cholesterol level was also higher in the group of high level of serum GGT activity in non-drinkers(P=0.052) but not in drinkers(P=0.981) of alcohol. In serum triglyceride, adjusted level was significantly higher in the group of high level of serum GGT activity in both non-drinkers(P=0.035) and drinkers(P=0.002) of alcohol. Conclusions: These results suggest the association of serum GGT activity and serum triglyceride, total cholesterol, or blood pressure in non-drinkres of alcohol.
