The purpose of this study was to investigate the health status and food habits of male college students in Seoul according to drinking habits. In order to identify risk factors, health surveys were conducted from October 2013 to December 2013. Average height, weight, and BMI of subjects were 175.47±5.27 cm, 67.93±9.28 kg, and 22.04±2.67 kg/m2, respectively. Weight and BMI were higher in the non-drinking groups compared to the drinking groups (p<0.05). Frequency of drinking was 2~3 times per month, and 52.4% of subjects started drinking when starting university. The motivation to start drinking was cited as “From necessity”. Reason for drinking was “Social relations”. The favorite kind of drink was beer. Rate of taking supplements was 24.4% of the subjects. Vitamin preparations were highest in drinking groups and non-drinking groups (p<0.05). The reasons for skipping meal were “too busy” in the drinking groups, and “oversleep” in the non-drinking groups (p<0.05). The preference for snacking in drinking groups were milk, milk products, and fast food, with the highest being listed first. The non-drinking groups preferred carbonated drinks and ice cream. The drinking groups need more education about their drinking habits. Drinking groups also need an increased intake of vegetables and fruits.

This study was performed with Korean adults to investigate Makgeolli drinking behavior, preference, and perception about Makgeolli and health, as well as Makgeolli complaints and prices. A survey questionnaire was formulated to obtain information on demographic variables, drinking habits, and perceptions about Makgeolli's function, price, and complaints. The questionnaire was distributed to 468 adults living in the capital area. The results are as follows. Makgeolli (16.1%) was third preferred, following Soju (45.1%) and beer (30.7%), and no significant differences were observed by gender and income, but the preference for Makgeolli increased with increasing age (p<0.001). According to the survey, the largest reason both genders drank Makgeolli was that it tastes good. Men preferred Makgeolli for its health effects and cheap price, while women preferred it for the atmosphere while drinking it. Also, older people and those with higher incomes preferred drinking Makgeolli for its health effect rather than its good taste (p<0.001 for each). No significant difference was observed by gender for the question "Do you think that Makgeolli has a health-promoting effect?" Overall, 51% of the subjects gave positive answers and only 5.9% gave negative answers. Significantly, older people and those with a higher income had a higher rate of answering positively to this question. Belching (45.1%) and headache (29.9%) were the most common symptoms among the side effects of drinking Makgeolli. No significant difference was observed by gender or income, but older people had a higher rate of belching and fewer headaches than younger people (p<0.001). Women had a significantly higher rate of perceiving that Makgeolli was cheap than men. Age and income differences did not influence price perception. To the question "What is the ideal price for high quality Makgeolli", 32.1% answered that the present rate (1,000 won) was ideal, and 59.4% answered that a price between 1,000 and 2,000 won was ideal. These results indicate that the high preference for Makgeolli is due to its good taste and health effects. However, belching and headache caused by drinking Makgeolli were the most common complaints and, thus, must be solved. Some opinions indicated that Makgeolli must eliminate its low-quality image, but, according to this survey, most subjects answered that the ideal price of higher-quality Makgeolli should be increased slightly, which would cause price resistance.

This study was conducted in order to investigate and compare anthropometric measurements, bone density, nutrient intake, blood composition and food habits between non-smoking, non-alcohol drinking and smoking, alcohol drinking male university students in Seoul, South Korea. The data for food habits and health-related behaviors were obtained by selfadministered questionnaires. The BQIs of the subjects were measured by Quantitative Ultrasound (QUS). The subjects were divided into two groups: NSND (non-smoking and non-alcohol drinking, n=62) group and General (smoking and alcohol drinking, n=160) group. The results were analyzed using the SPSS program and were as follows: The average heights, weights, and BMIs of the two groups were 173.3 cm, 66.5 kg and 22.1 and 173.4 cm, 68.7 kg and 22.9, respectively. There were no differences between the groups regarding height, weight or BMI. SBP and DBP, however, were significantly higher in the general group than in the NSND group (p〈0.01). The BQIs, Z-scores and T-scores of the two groups were 99.83, -0.23, and -0.31 and 98.24, -0.27 and -0.39, respectively, producing no significant differences between the two groups. The percentages for normal bone status, osteopenia and osteoporosis were 83.88%, 16.12% and 0.0% and 74.37%, 25.62% and 0.01%, respectively. Mean intakes of animal protein (p〈0.05), animal fat (p〈0.05), fiber (p〈0.05), animal Ca(p〈0.05), animal Fe (p〈0.001), Zn(p〈0.05), vitamin B1 (p〈0.05) and niacin (p〈0.05) were significantly different between the two groups, and mean serum levels of SGOT (p〈0.01), SGPT (p〈0.001), γ-GTP (p〈0.001), triglycerides (p〈0.01), total cholesterol (p〈0.05) and hematocrit (p〈0.05) were also significantly different between the two groups. Overall, there were no differences in meal regularity, frequency of snacking, reasons for overeating, exercise and defecation between the groups. However, favorite foods (p〈0.05) and night-time meals (p〈0.05) were significantly different. In conclusion, the health status of the NSND group was superior compared to the general group. Thus, students who smoke and alcohol drink should receive a practical and systematically-organized education regarding the increased health benefits of quitting smoking and alcohol drinking.
