This research analyzed the hematological index and health related habits such as alcohol drinking, smoking and exercise, by classifying 539 middle-aged men (age: 40 - 59) into a normal weight group, an overweight group and an obese group, according to BMI (body mass index). As a result, 33.6% (n = 181) of subjects had a BMI of 23 or less and 30.2% (n = 163) were overweight and 36.2% (n = 195) were obese (BMI > 25). The average systolic/diastolic blood pressures of total subjects were 130.96mmHg and 80.38mmHg, respectively. And the average pressure of normal subjects was 126.85/77.57mmHg, which was significantly lower than in overweight and obese subjects. Diastolic blood pressure shows significant differences among the three groups. The overall average cholesterol level of normal subjects was 193.81mg/dl, which was significantly lower than those in overweight subjects. Those in obese subjects were significantly higher than in overweight subjects. The GOT (glutamic oxaloacetic transaminase), GPT (glutamic pyrutic transaminase), ${\gamma}$-GTP (gamma-glutamyl transpeptidase) levels of obese subjects were significantly higher than in the overweight subjects. Frequency of alcohol drinking showed no significant difference among the groups. The smoking ratio in the obese group was higher than in the normal and overweight groups. The ratio of smokers was 53.1 %, and the alcohol drinking ratio was 81.0% of the total subjects. The frequency of drinking showed significant correlations with systolic blood pressure (p < 0.05) and diastolic blood pressures (p < 0.01) and ${\gamma}$-GTP (p < 0.01). The duration of smoking showed a negative correlation (p < 0.01) with diastolic blood pressure, total cholesterol and ${\gamma}$-GTP. On the other hand, exercising frequency showed negative correlations with blood glucose, ${\gamma}$-GTP and GPT(p < 0.01). These hematological indices were correlated with health related habits such as alcohol drinking, smoking and lack of exercise, and to be the cause of chronic diseases. Therefore, proper nutritional education is needed to establish advisable health related habits to maintain proper body weight. (J Community Nutrition 8(2): 63-68, 2006)

The purpose of this study was to conduct a survey of general status of drinking culture among college students in Korea. Three hundred college students answered the self-administered questionnaire from May 6 to May 10 in 2009. The questionnaire consisted of drinking-related behavior by gender, recognition and need for moderation in drinking program, and the reason for stopping drinking by gender. The statistical method was done by SPSS WIN version 14.0. The first drinking time was high school comprising 41.0% of the respondents. The reason for drinking was to get the personal relationship. The experience of blackout was 50.3% in twice a year and 26.0% in twice per six months. The reasons for stopping drinking were health problem(36.9%), personal relationship(34.5%), and financial difficulty(20.8%). These results will make it possible to establish the right drinking habit, prevention of sexual violence and vehicle accident and health promotion of the students.

This study was conducted to investigate the relationship between alcohol consumption, physical activity and breast cancer risk in Korean women. Newly histologically identified cases (N = 108) were selected at Hanyang and Soonchunhyang University Hospitals in Seoul, from January 1998 to August 1999. Hospital-based controls (n = 121) were the patients who visited at the same hospital in the department of plastic surgery, general surgery and opthalmology. Subjects were asked informations on demographic, reproductive, and history of breast feeding as well as physical activity, exercise habit, alcohol consumption by individual interview. Odds ratio (OR) and 95% Confidence Intervals (CI) were calculated by using unconditional logistic regression after adjusted for confounding factors. Among postmenopausal women, the risk of breast cancer increased with increasing alcohol drinking: relative risk for the highest group ( $\geq$ 150 g per week) compared with the lowest group (never drinking) was 2.05 (CI=1.74-3.79). Association of exercise and high physical activity for breast cancer appeared to be limited to women with high physical index among postmenopausal women. We observed decreasing risk of breast cancer with increasing physical activity index among postmenopausal women (OR=0.49,95% CI=0.56-0.92). Results of this study support a protective effects of physical activity during adulthood for breast cancer. (Korean J Nutrition 36(1): 40-48, 2003)

Purpose: This study aimed to identify the level of knowledge on preventing cardiovascular disease (CVD) and nicotine dependency among smoking male college students, and to examine the predicting factors of nicotine dependency. Methods: This study was conducted as cross-sectional descriptive research using structured questionnaires. Data were collected from 411 smoking male college students ($22.5{\pm}2.59$ yr) at two universities located in two cities in Korea from September 2012 to April 2013. Logistic regression analysis was performed to estimate age-adjusted odds ratios of nicotine dependency. Results: The mean value of nicotine dependency was $4.2{\pm}1.96$ and the percentage of participants who had strong nicotine dependency (${\geq}7$) was 10.7%. Logistic regression analysis showed that, when adjustment was made for age, nicotine dependency was predicted by the frequency of alcohol drinking (${\geq}3$ times/week), knowledge on CVD prevention, the age starting drinking, and the total length of smoking. Conclusion: Nicotine dependency was strongly related to the frequency of drinking alcohol and lower knowledge on CVD prevention. Therefore, male college students who have a dependent smoking habit and drink alcohol frequently need to take more interest in health through educational counseling to modify their lifestyle behaviors and to have preventive knowledge related to CVD.

The purpose of this study is to analyze the contents of the questionnaires used in dietary surveys and to evaluate each item in relation to the item construction strategy. Articles of which the contents were related to food, nutrition, diet, dietary behavior, and related areas. Published from 1997 to 1999 were searched fir and a total of 121 questionnaires were collected and analyzed. The questions in the questionnaires were classified into related areas and sub-areas. Among the keywords in the title of the articles, the term 'nutritional status'(or 'dietary intake status') was most frequently used. The terms such as dietary status, obesity, health, food habit, and dietary behavior were also frequency used. Major topics of the items in the questionnaires varied according to the life cycle of the subjects of the study. The topics most frequently asked in each lift cycle were as follows : overeating, snack, and food preference for preschool- and school-aged children ; anthropometry, weight control, and snack for middle and highschool students : meal skipping, smoking, and drinking for college students : disease, smoking, drinking, and exercise for adults : and smoking, drinking, disease and perceived health for the elderly. Inappropriate questions with complicated language, typographic and grammatic errors, unnecessary words, and negative questions were found. Therefore, care should be taken to construct each question so as to avoid possible misinterpretation. Also, a standardized questionnaire be developed for survey researchers.

The purpose of this study was to identify the association between health-related behaviors including smoking, alcohol intake, and the practice of a low-salt diet using data from a Community Health Survey conducted in 2008. The study subjects were 129,151 persons (19 years and older) without cardiovascular diseases or diabetes mellitus diagnosis history. An index for evaluating low salinity was created by summing three low salinity-related questions (range: 0~3), and a low-salt diet was defined if the index of low salinity was 3. We examined the levels of smoking and alcohol intake according to the index of low salinity, and conducted multiple logistic regression analysis to examine the odds ratios of low-salt diet practice in relation to smoking and drinking behavior, adjusting for general characteristics. The smoking and drinking status significantly improved as the level of low salinity index increase. Adjusting for general characteristics, those with smoking, alcohol intake, or a combined habit of the two behaviors had significantly lower odds ratios for practice of a low-salt diet. In conclusion, smoking and drinking behavior were negatively associated with the practice of a low-salt diet. Based on these findings, it may be necessary to have comprehensive nutritional education programs that consider the multiple effects of smoking, drinking, and a low-salt diet.

We investigate how smokers and drinkers have influenced on self-reported risk assessment and workplace injuries, using the Korean Working Conditions Survey. Our empirical results indicate that persistent smoking habit raises workers' job risk assessments and work injuries significantly. Also, former smokers notice relatively higher risk assessments in various work activities, but they are less likely to affect work injuries. More frequent drinking behavior leads to a positive effect of job risk perception and workplace injuries. Regular smoking with frequent drinking for high income classes, however, have significantly reduced the chance of work injuries. Furthermore, establishing smoking-designated area at the workplace makes workers reduce workplace accidents positively. Therefore, the network effect of smoking and drinking behaviors in private circle levels is suggested to extend into public and constructive activies at the workplace levels for sharing useful and productive information, which will eventually reduce workplace injuries dramatically.

We have conducted questionnaire and measured serum kidney function tests on 156 patients whom have received a treatment at a local Oriental medicine clinic in Seoul from Sept. 1, 2002 to Dec. 31, 2002. Patients were categorized into five groups. The groups are control(10 samples), herbal extract group(41 samples), herbal pills group(5samples), western medicines(45samples), and combination group(55 samples). This study was conducted to investigate how these treatment methods can affect the kidney functions. Following results were obtained : 1) Most of the research subjects were male(103 individuals) living in large urban area, with a drinking habit, highly educated, and with normal marriage. For the treatment history, 45 individuals received western medicine treatment(28.85%), 46 with Oriental medicine(29.49%), and 55patients (35.26%) experienced both forms of the treatment. 2) For measuring Mean(SD) of serum kidney functions for all the research subjects, Bun was 12.16(3.90)g/dl, 0.51(0.19) g/dl for Creatinine, and 4.64(1.49)g/dl for Uric acid. All the measurements were within the normal range. 3) Confounding variables which may affect the kidney functions such as age, smoking, drinking, occupation, and residency were eliminated in calculation and no significant differences were witnessed between the control and experiment groups. 4) In measuring affects of treatment duration on the kidney functions, no statistical significances were shown in multiple regression's ${\beta}(SE)$ values. 5) Correlations affecting the kidney functions are duration of drinking, drinking volume per round, drinking volume per week, smoking, gender, and age difference caused significant correlations. From the above results, we can deduce that taking herbal and western medicine didn't cause significant effects between the control and experiment groups in the kidney functions. Further research is needed in this field to verify this evidence by adding odds ratios and etc.

Purpose: The purpose of this study was to examine the relationship between health behavior and residence types of university students. Methods: Using a quota sampling method by gender and residence type, 364 male and female students (126 students who live in their own house (SH), 123 students who live in board themselves (SB), and 115 students who live in a dormitory (SD)) were selected from one university in Ulsan. Five categories on smoking, drinking, exercise, eating, and sleeping were used to describe health behavior of the participants. Results: Difference of smoking, drinking, eating, and sleeping habits was existed in classifications of residence types of participants. Regarding the current smoking rate, frequency of drinking, and amount of drinking, the result of SB was higher than that of SH or SD. The score of eating habit of SB was lower than that of SH or SD. SD exercised much less than SB or SH. Conclusion: To prevent aggravation of SB health habits, an education program for comprehensive health promotion is needed for university students to improve their smoking, drinking, exercise, and eating habits.

This study aims to find out the prevalence of smoking, and to analyze the effect of smoking for health status, and then to emphasize the necessity of stop smoking. The data used in this study are obtained from periodic health care programe at Health Care Center in a suburban hospital, and selected 435 males who have occupation. The independent varibles chosen for the analysis are general charactersitic variables and smoking habit. The dependent variables are designed to cover the health status of individual cases, and include blood pressure, blood cholesterol level with HDL-cholesterol and blood triglyceride level, recent symptoms and recently being managed diseases. The result of this study are summarized as follows. 1) Percentage of smoker by the age groups is highest in 4th decade, being 71.1%. The second and third ranks are 6th and 7th decades, being 53.5% and 44.4%, respectively. 2) In the view of socio-economic levels, smoking rate is higher in the groups who live at rural area and whoes occupation is labor or merchant. Smoking rate is significantly higher in the heavy drinking group. 3) Among the atherosclerotic risk factors, which include hypertension, HDL-cholesterol by total cholesterol ratio lower than 0.2 and triglyceride level higher than 200gm/dl, hypertension was not statistically associated with smoking, but others revealed statistically high association with smoking. 4) The groups who have the symptoms of severe fatigue, gastrointestinal symptoms, pulmonary symptoms, palpitation and chest tightness havepositive association with smoking. 5) The groups who have hypertension with cardiovascular diseases and gastrointestinal diseases showed highly significant association with non-smoking. 6) In relation of the smoking habit to the atherosclerotic risk factor index, smokers have more atherosclerotic risk factors, but that is not statistically significant. 7) In relation of the smoking habit to the recent symptom index, smokers have more symptoms than non-smokers with statistical significance. In conclusion, smokers have worse health status than non-smokers especially in the atherosclerotic risk factors such as hypertension or abnormal blood lipid status and have more symptoms such as severe fatigue, gastrointestinal symptoms, pulmonary symptoms, palpitation and chest tightness. And the campaingn against smoking should direct for the male in 4th decade because they have highest smoking rate.
