Body antioxidant status is an important factor in the prevention of many chronic diseases caused by oxidative stress, especially in the elderly and is affected by health-related habits, such as smoking, drinking and regular physical activity. The aim of this study was to investigate the relationship between these health-related habits and plasma antioxidant status in the elderly. Plasma antioxidant status was examined by determining plasma levels of antioxidant vitamins (vitamin C, A, E, $\beta$ -carotene), total antioxidant status (TAS) and thiobarbituric acid-reactive substance (TBARS) . The subjects included 225 elderly persons aged over 60 yews (63 males, 162 females) living in the Ulsan area. They were interviewed to collect data on their general characteristics and health behaviors such as smoking, exercise and alcohol consumption by means of questionnaires. Their dietary intakes were obtained by means of semi-quantitative food frequency questionnaires (FFQ) The study population was divided into two or three groups according to their smoking, drinking, and exercise status. The ratio of smoker, drinker and exerciser was 16.7%, 31.0% and 44.2% respectively. The dietary antioxidant vitamin intakes were not significantly different among groups of smoking and drinking status, but tended to be higher in non-smokers and non-drinkers than in smokers and drinkers. Plasma vitamin C and $\beta$ -carotene levels were significantly higher in non-smokers, but Plasma vitamin A and TBARS levels were significantly lower in non-smokers than in smokers. Plasma TAS was not significantly different among the smoking groups, but showed a tendency to decrease with an increase in the number of packyear. Plasma vitamin C and $\beta$ -carotene levels of the non-drinkers were higher than those of drinkers and past-drinkers, but plasma vitamin A, C, E, TAS and TBARS showed no difference among the groups of drinker. All vitamin intakes of the exercisers were slightly higher than those of the non-exercisers, but vitamin C intake was significantly higher in female exercisers than in non-exercisers. Plasma $\beta$ -carotene levels were significantly higher in male exercisers and plasma vitamin A, C, E, TAS and TBARS levels tended to be higher in exercisers than in non-exercisers. These results suggested that change to non-smoker, modulation of alcohol consumption and regular exercise could enhance antioxidant defences against reactive oxygen species and might increase the likelihood of a healthier life span.

This study is a descriptive research for understanding the health behaviors, job stress, and musculoskeletal subjective symptoms of university employees, and also for examining the influence factors having effects on the musculoskeletal subjective symptoms. Targeting total 158 university employees, the data was collected from July to August 2020. In the results of this study, the characteristics related to health behaviors showed the percentages like the rate of drinking(68.6%), rate of smokers(9.6%), rate of exercising three times or more a week(15.4%), and the rate of regular eating habit(64.7%). The mean score of job stress was 63.7. The musculoskeletal disease symptom group falling under the occupational musculoskeletal subjective symptom standard of NIOSH was 18.6%, and the musculoskeletal subjective symptom of shoulders showed the highest rate. Also, the 29.5% of research subjects responded that the cause for their musculoskeletal pain was work. As the factors having effects on the musculoskeletal subjective symptoms, the sex, age, career experience, and job stress had significant effects on the subjective symptom of shoulder part(p<.01) while the regular exercise had significant effects on the subjective symptom of waist(p<.05). The educational background and regular meals had significant effects on the subjective symptom of legs and knees(p<.05). Thus, in order to prevent the musculoskeletal diseases of university employees, it would be necessary to develop/apply the programs for the relief of job stress, regular exercise, and regular meals.

We investigated the association between dietary habits/food group consumption patterns and early risk of metabolic syndrome (MetS), a main cause for metabolic disease. Study participants were recruited from the health promotion center in Dong-A University Hospital and public advertisement. Study subjects (n = 243, 21-80 years) were categorized into three groups: Super-healthy (MetS risk factor [MetS RF] = 0, n = 111), MetS-risk carriers (MetS RF = 1-2, n = 96), and MetS (MetS $RF{\geq}3$, n = 27). Higher regularity in dietary habits (breakfast-everyday, regular eating time, non-frequent overeating, and non-frequent eating-out) was observed in the Super-healthy group than in the MetS-risk carriers, and particularly in the MetS subjects. The relationship between food group consumption patterns and MetS-risk related parameters were investigated with adjustment for confounding factors. Fruit consumption was positively associated with HDL-cholesterol, and tended to be negatively associated with waist circumference, triglyceride, LDL-cholesterol, and insulin resistance (IR). The consumption of low-fat meats and fish, and vegetables was negatively associated with hs-CRP. Specifically, the consumption of seafoods belonging to the low-fat fish was negatively associated with fasting glucose, hs-CRP, and interleukin (IL)-6. Anchovy/dried white baits consumption was negatively associated with fasting insulin and IR. Green-yellow vegetables consumption was negatively associated with fasting insulin, IR, and hs-CRP. On the other hand, sugars and fast-foods were positively associated with LDL-cholesterol. Additionally, fast-foods consumption was positively associated with hs-CRP and IL-6 levels. In conclusion, dietary habits/food group consumption patterns are closely associated with MetS-risk related parameters in Koreans. It may suggest useful information to educate people to properly select healthy foods for early prevention of MetS.

The purpose of this study was to identify the risk factors of osteoporosis. The data were collected from women who visited Physical Examination Center of a university hospital located in Taejon during the period of September 1997-August 1998. The sample was divided into two groups(the osteoporosis group of 44 cases and the control group of 66 cases). The results were summarized as follows ; 1. Sociodemographic characteristics(education and family income) and BMI showed no significant difference between the osteoporosis group and the control group. 2. There was no significant difference in coffee, unbalanced diet, diet method and meal habit between the osteoporosis group and the control group. 3. The osteoporosis group reported more incidence of operative menopause due to hysterectomy and oophorectomy, but this was not statistically significant. There was no significant difference in use of oral pill use, past disease and family history of fracture between the osteoporosis group and the control group, but the odds ratio(OR 3.11, 95% CI : 1.30-7.41) of present illness was statistically significant in the osteoporosis group. 4. There was no significant difference in the reproductive history including number of delivery and abortion and feeding method between the osteoporosis group and the control group. 5. The osteoporosis group showed significant results of lower menopausal age, shorter duration of menstruation and longer duration after menopause compared to the control group. 6. The osteoporosis group reported significantly lower level of physical activity in such variables as work activity and walking time. 7. A logistic analysis showed that shorter period of menstruation, lower level of physical activity, non-alcohol drinking group, and presence of disease were related to the possibility of occurring of osteoporosis.

Background: Many chronic diseases are associated with the lifestyle such as smoking, alcohol drinking and exercise. Attention is increasingly paid on the effect of exercise for the management of chronic disease these days. Objective: The purpose of this study was to evaluate the status of the smoking habit, alcohol drinking and physical exercise of the patients with chronic diseases. Methods: Total 793 persons(normal:422, chronic disease patients:371) in a hospital were questioned regarding the habits of smoking and alcohol drinking, and a practice of physical exercise in 1999. The patients with chronic illness were divided into three groups(Group I included the patients of hypertension and diabetes mellitus. Group II includes respiratory disease and cancer. Group III included liver disease). The rate of exercise, the rate of smoking cessation and the rate of abstinence were assessed. In logistic regression analysis with each independent variables in each disease groups (I, II and III, odds ratio for the presence of disease was controlled for age and education. Results: The rate of exercise, the rate of smoking cessation and the rate of abstinence was 31.5%, 27.3% and 9.5% in the patients with chronic disease, respectively. In control group, those were 31.5%, 21% and 2.1%, respectively. In logistic regression analysis with exercise as independent variable, odds ratios(95% CI for age and education were significantly high, with smoking cessation, odds ratio for age was high and with abstinence, odds ratio for disease with high in all disease groups. Conclusion: It was suggested that an effort for proper changes of lifestyle related to disease such as smoking, alcohol drinking and exercise should be intervened in the patients with chronic diseases.

This study has analyzed the association of physical activity and television watching time with obesity in 30-50 aged women from middle income town in Busan city area. Data were obtained using a questionnaire, including information about physical activity, TV watching time and health habit; social data regarding educational level and monthly income; family history of chronic condition. Height and weight were measured. Outcome variable was obesity, defined as a body mass index 25 kg/m$^2$ or greater. Odds ratios (OR) for obesity were estimated by multivariate logistic regression, and interpreted as a relative risk of obesity. The prevalence of obesity was 11.8%. The mean BMI of obese women was 26.9 kg/m$^2$. The OR of obesity was higher in subject of 40s than 30s. Subjects who had higher educational level presented lower OR than those of elementary or middle school education. Family income was not associated with obesity. Women having a family history of chronic condition had higher risk of obesity than those who did not have it. The OR was lower in active people at work (OR = 0.51; 95% CI = 0.26 - 0.98) than in inactive ones, and the ORs associated with regular exercise or activity at leisure time were not statistically different. However, subjects watching TV $\geq$ 3.5 hr/day showed higher OR (OR = 2.34; 95% CI = 1.16 - 4.74), compared with those watching TV $\geq$ 1.5 hr/day. Association of the joint classification of physical activity variables with obesity was estimated. The highest relative risk of 5.99 was in women in physically inactive at work and high category of TV watching ($\geq$ 3.5 hr/day). Even in women in active at work, the watching TV $\geq$ 3.5 hr/day made them have the high OR (OR = 2.44; 95% CI = 1.03 - 5.77). And at each time level of TV watching, the increasing activity level at work was associated with lower OR for obesity. These findings suggest that both TV watching time and physical activity at work were related to obesity in adult female, each with independent effects on obesity. TV watching time seems to be a significant factor that could partly evaluate the energy expenditure.

This study was conducted to determine factors affecting detection threshold and the optimally-preferred concentration for sweet taste, since investigation into factors decreasing sensitivity or increasing preference for sweet taste is important to prevent overconsumption of simple sugar. Subjects were 70 first-grade middle school students in the Gyeonggi-Do. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly were determined by sensory evaluation. A self-administered questionnaire was used to obtain the information regarding health-related lifestyle practices, dietary habits, preference for and eating frequency of Westernized foods and frequencies of eating foods other than home-made. The detection threshold concentration of sucrose solution and the optimally-preferred sucrose concentration of omija jelly of the subjects were 0.204% and 14.44%, respectively. Subjects who exercise less (< 30 minutes/week except PE class), skipping meals (${\geq}$ 3/week), type of breakfast rather than traditional Korean meal and frequent eating out and buying foods from school tuck-shop tended to have higher sweet taste threshold. There was significant positive correlation between the sucrose threshold concentration and fried chicken preference or eating frequency of hamburger. Those who exercise less (< 30 minutes/week except PE class) did have significantly higher optimally-preferred sweetness of omija jelly, which tended to be higher in the subjects who had more (${\geq}$ 4 out of 10) behavioral or psychological stress symptoms and who had early getting-up time (before 7 am). There was significant positive correlations between the optimally-preferred sweetness of omija jelly and pizza preference, instant noodle eating frequency or sum of eating frequencies of five fast foods. From the results of this study, it was suggested that middle school students should make efforts to stop skipping meals, exercise more, eat Korean traditional breakfast and reduce the frequencies of eating out and using instant/fast foods in order to prevent overconsumption simple sugar.

A special type of indigenous knowledge on plants utilization and farming system was explored by the Garo tribe community in the North-East region of Bangladesh, which correspond to the severe dependence on homestead forest. Results show that the Garo are totally dependent on the natural resources and that the extent of their dependency is faithfully reflected in their ethno-botanical knowledge. Dependencies that the study addressed focused on various aspects of food, fruit, energy, timber and health care on plants products. Garo tribe community in Bangladesh followed agrosilvipastoral system in their homesteads. They have indigenous hunting procedure to trap the animal in the forest. A total of 9 foods, 15 fruits, 12 energy-producing and 11 timber species was found and recorded that the Garo used in their daily life. Moreover, Garo used 23 medicinal plants species and have vast indigenous knowledge about using herbal medicine in daily health care practices. The Garo women do mostly the household activities, managing homestead forest and helping agricultural field where men perform all hard working activities like ploughing, cutting trees, digging the soil, preparation of horticultural and agricultural land, hunting, etc. The overall quality of life of the Garo could be considerably upgraded if ethno-botanical issues and their own indigenous knowledge will complement with scientific knowledge. The findings of the study conclude that the conservation of the indigenous knowledge of the Garo tribe related to plants utilization can also be turned to good account in forest conservation and is an important tool in this tribal area of Bangladesh.
