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.

The purpose of this study was to compare the awareness of dietary patterns and health of full-time and employed housewives. The investigation gathered information on general characteristics, dietary lifestyle, nutritional status, and health by questionnaire as well as anthropometric measurements. The subjects included housewives living in Seoul and Gyeonggi Province (86 full-time and 127 working housewives) during November 2009 to January 2010. The average age, height, and weight of the housewives were 45.8±7.6 yr, 161.0±8.4 cm, and 55.7±6.3 kg, respectively. The average monthly income of the households was 3 million to 5 million won (31.4% full-time and 37.0% working housewives), and their average food expense was 200,000 to 500,000 won (46.5% full-time and 48.1% working housewives). More than 90% of the studied homes were nuclear families and the most common number of children was 2 to 3 (79.1% full-time and 76.4% working housewives). The ratio of employed housewives who ate regular meals was 35.4%, but that of the full-time housewives was 48.2% (p〈0.05). Of the working housewives, 7.1% never ate breakfast and the primary reason for skipping breakfast was 'busy in the morning' (61.1%). The type of food that the housewives preferred when eating out was Korean food, both for the full-time and employed housewives (76.0%). All the housewives overate calories and the full-time housewives ate more protein, fat, vitamin A, vitamin B1, vitamin B6, niacin, vitamin C, vitamin E, folic acid, and cholesterol than the employed housewives (p〈0.05). Both the full-time and employed housewives were more satisfied with supper than with other meals. About 30.6% of the full-time and 33.9% of the working housewives had no interest in health, but answered that regular exercise was very important for health (33.3% full-time and 39.7% working housewives). In conclusion, working housewives have poor dietary habits and nutrient intakes, thus substantial measures to improve these problems are urgently needed.

To elucidate the effects of an obesity control program on body composition and serum lipid levels, 31 obese elementary students (male: 25, female: 6) residing in the Gyeonggi area were evaluated and their body composition, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG (triglyceride) were analyzed. The average age, height, weight and BMI (body mass index) were 11.52±1.00 yrs, 151.96±8.04 cm, 68.21±9.03 kg and 29.40±1.79 kg/m2 for the males, respectively, and 11.17±1.17 yrs, 147.83±5.15 cm, 65.05±10.86 kg and 29.62±3.24 kg/m2 for the females, respectively. There was a significant decrease in BMI for males (p〈0.001) and females (p〈0.05). There were also significant changes in all of the biochemical levels evaluated before and after the study. Specifically, the total cholesterol, LDL-cholesterol and TG level decreased after the obesity control program, while the HDL-cholesterol level increased after the program. These results indicate that obesity control programs do change the BMI, serum total cholesterol, HDL-cholesterol, LDL-cholesterol and TG levels in obese elementary students. Thus, obesity control programs are urgently needed to prevent degenerative disease and decrease obesity among children in elementary school.

This study was conducted to investigate bone density and food behavior of middle-aged (〈65-years-of-age) and oldaged women (≥65-years-of-age) in the Seoul area of Korea. Average height and weight, body mass index, body fat percentage, and waist-hip ration (WHR) of the middle-aged participants were 158.0 cm, 58.4 kg, 23.3, 29.7%, and 0.88. Corresponding measurements for old-aged participants were 152.6 cm, 56.3 kg, 24.1, 33.1%, and 0.93. T- and Z-scores for middle-aged women were -1.20 and -0.21, and those of old-aged women were -2.02 and -0.49. Osteopenia and osteoporosis percentage of middle- and old-aged women were 41.2% and 14.7%, and 45.2% and 37.1%, respectively. Significant differences were evident concerning between-meal, overeating, exercise, and nutritional supplementation among the two groups. Middle-aged women displayed a positive relationships between bone density and the parameters of height (p〈0.05), weight (p〈0.05), exercise (p〈0.05), consumption of soybean and soybean-processed food (p〈0.05), and negative relationships between bone density and the parameters of WHR (p〈0.001), consumption of meat and meatprocessed food (p〈0.05), and tea drinking (p〈0.05). In old-aged women group, positive relationships were evident for bone density and the parameters of height (p〈0.05), weight (p〈0.05), exercise (p〈0.05), nutritional supplementation (p〈0.05), and consumption of soybean and soybean-processed food (p〈0.05). The results reveal a link between healthy bones and desirable food behavior, indicating the importance of a practical and systematically organized food behavior education program for middle- and old-aged Korean women.

The principal objective of this study was to assess the bone density and processed food intake behavior of middle-aged and elderly women in the Seoul area. The subjects were assigned to one of the following groups on the basis of BMI: namely, the underweight, normal, and overweight groups. The results are summarized as follows: The average BMI and systolic blood pressure of the three groups were 19.0, 127.3 mmHg; 22.4, 132.8 mmHg; and 26.8, 136.1 mmHg respectively. The BQI and T-scores of the three groups were as follows: 56.6, -2.50; 62.3, -2.22; 66.0, -2.03 respectively. The bone status of the three groups, in terms of the percentage of normal and osteoporosis, were 9.5%, 52.4%; 8.3% 33.0%; and 8.8%, 23.6% respectively. We noted no significant differences in processed food intake (frozen, cold and can processed food, instant and convenience store food, basic side dishes) behavior among the three groups. However, we recorded a negative value between processed food intake and bone density (BQI, T-score, %young adult, Z-score, %age-matched) generally. In particular, ramyeon (r=-0.1574, p<0.05) and cup-ramyeon (r=-0.1996, p<0.05) intake were significantly associated with the T-scores of bone density levels. The results of this study revealed that processed food intake was not generally desirable for healthy bone. Thus, practically and systematically organized education regarding a good and healthy dietary life is highly recommended.

This study was conducted to investigate on bone density and nutrient intake of university students in Seoul area. Nutrient intake data were obtained by using the 24-hour recall method to evaluate the usual diet of the subjects. BQI(bone quality index) of the subjects was measured by an Quantitative Ultrasound (QUS). The results are summarized as follows: The average height, weight, BMI of the male and female student were 173.3 cm, 68.5 kg, 22.7; 161.4 cm, 54.2 kg, 20.8, respectively. The BQI and Z-score of the subjects were 99.50, -0.69 in male student group, and 82.6, -1.15 in female student group, respectively. Normal, osteopenia and osteoporosis percentage by bone status were 73.8%, 24.9%, 1.3% in male student group, and 39.8%, 57.6%, 2.6% in female student group, respectively. Energy intake of male and female group were 71.7%, 79.1% of EER(estimated energy requirement) respectively. Fiber, Ca, Vit B2, niacin, folic acid, Vit C intake were less than RI(recommended intake) and protein, phosphorus intake were higher than RI in subjects. Nutrient intake were not significantly related with BQI in male and female groups generally.

This study was conducted to investigate factors affecting gone density of university students in Seoul area. Data for food habits, exercise and health-related behaviors were obtained by self administered questionnaires. BQI(bone quality index) of the subjects was measured by an Quantitative Ultrasound(QUS). The results are summarized as follows: The average hight, weight BMI and osteopenia percentage of the male and female student were 173.3cm, 68.6kg, 22.7 and 24.2%; 161.4cm, 54.4kg, 20.9 and 55.5%, respectively. The BQI and Z-score of the subjects were 99.6, -0.3 in male student group, and 82.7, -1.1 in female student group, respectively. Height, weight, fat weight, fat mass and BMI were positively related with BQI in female group. BQI was positively affected by breakfast and frequence exercise in male student group. In female student group, frequency exercise was positively related with BQI. The result of this study revealed that the desirable food habits, dietary behaviors and health-related lifestyles may have a beneficial effect on bone density. They should have practically and systematically organized nutritional education on optimum body weight, good eating habits, weight bearing exercise for higher bone density level.

The purpose of the this study was to investigate the dietary behavior and the food habits of university freshman according to body mass index. Questionnaire were completed by 532 students in university freshman. The data were analyzed by SAS program. The results were as follows : The means of normal group's height, weight were 175.00±5.98cm, 72.93±10.20kg for male students and 162.00±4.75cm, 51.97±4.98kg for female students. Under 20 of BMI(body mass index) among students were 69.7% for male and 9.6% for female. Twenty~twenty five(20~25) of BMI were 21.9% for male and 40.2% for female. The consumption of milk, oil and animal fat were significant according to BMI. There was high significant difference in the score of exercise and activity. In the self recognition of body shape 59.0% of male and 52.6% of female in normal weight group answered that their weight had to be a little thin. Self satisfaction rate was significantly higher in under weight group compared to normal weight group. This study suggest that a comprehensive nutrition education program is need for university students to improve desirable food habits and recognition of rate of figure.

This study was to investigate the food habits and the dietary behaviors of university students. Questionnaires were completed by 492 students in five different departments. The data were analyzed by SAS program. The results are summarized as follows: Fifty(10.2%) of respondents were vegetarians, 81(16.4%) were heavy meat eaters and all the others were light meat eaters. All students had their biggest meal at supper. Three hundred and ninety-three(79.9%) of the respondents usually had rice for breakfast. Three hundred -sixteen(64.2%) ate 3 meals a day, 155(31.5%) ate 2 meals and all the others ate 1 meal or more than 3 meals. The length of mealtime was 30 minutes in 268(54.5%), 10 minutes in 209(42.5%) and more than 1 hour in all the others. Respondents considered taste the most important meal factor with nutrition, hygiene, and amount ranked accordingly. A majority(63.0%) of respondents ate occasionally ate between meals, while 28.1% snacked frequently, and 8.9% ate no snacks. Although nutrition dept. students had studied nutrition subject, some results of nutrition dept. students were desirable and others were undesirable in dietary behaviors. Therefore they should have a nutritional education program to improve their food habits and the dietary behaviors for students' health. And nutritional education program should be organized practically and systematically.
