This study was conducted to assess the nutrient intake patterns among urban and rural adolescents and to investigate the effects due to parent's socioeconomic status and other factors, such as mother's job, family type and regular exercise on that pattern. 2,455 middle and high school students living in Seoul and Yangpong, Kyounffi-Do participated in a self-administered questionnaire that was used to collect data. The one-day dietary intake was surveyed through a 24-hour recall method. The factors significantly different between urban and rural adolescents according to monthly income, parent's education level, mother's job, family type and exercise. Income, the parents' education level and regular exercise were associated with the patterns of nutrient intakes as a percent of the RDA. So, when adjusted for parental income, the father's and mother's education level and regular exercise, there were no signifcant differences within the patterns of nutritional intake between urban and rural adolescents. The results provided the information regarding the determinants of nutrient status among adolescents and were expected to be helpful for planning school health promotion programs.
Background: The purpose of this study was to identify the risk factors influencing cognitive function and life satisfaction in elderly living alone. Methods: It was cross-sectional descriptive study by using secondary data from the 2014 national survey of Korean elderly. The study sample consisted of 2,249 subjects who live alone, aged 65 years old and over. Data were analyzed frequency analysis, ${\chi}^2$-test, t-test, ANOVA and Logistic regression analysis. Results: The risk factors that significantly influenced cognitive function were old age, bereavement, lack of education, no regular exercise and low socio-cultural activity satisfaction. The risk factors that significantly influenced life satisfaction were no bereavement, lack of education, no work, negative evaluation of health status, diagnosis of depression and no regular exercise. Also experience of emotional and economical abuse, neglect of financial support and low cognitive function were identified risk factors of life satisfaction. Conclusions: The elderly living alone with risk factors of cognitive decline should be interested. To prevent or delay cognitive impairment, regular exercise and socio-cultural activities were recommended. It was suggested that the promotion of cognitive function, appropriate work and exercise, and social efforts to prevent abuse and neglect can contribute to improving life satisfaction of elderly living alone.
Purpose: The purpose of this study was to compare the use of health services and health expenditures between non-exercise and exercise groups of diabetic patients and among three groups divided according to exercise intensity. Methods: Data were obtained from the Korean Health Panel Survey of 2011. The participants of this study were 864 diabetic patients who did exercise (walk, moderate exercise, or vigorous exercise) or not. Data were subsequently analyzed using the SPSS 21 Program. Results: The exercise group showed higher percentages of medication compliance, non-smokers, and regular diet than the non-exercise group. The hospitalization percentage, the number of outpatient hospital visits, and health expenditures were higher in the non-exercise group than in the exercise group. There was no difference among the three groups divided according to exercise intensity in the use of health services and health expenditures. Conclusion: These results show that exercise is a way to reduce diabetic patients' use of health services and their health expenditures.
The purpose of the this study was to examine the effects of 12 weeks of regular aerobic exercise training on hepatic enzymes in type 2 diabetes mellitus (T2DM) patients. The subjects consisted of 13 middle-aged male type 2 diabetes mellitus (T2DM) patients, all of whom had no other complications. Subjects participated in regular aerobic exercise training for 12 weeks, in which they started to exercise for $20{\sim}60$ min, at $60{\sim}80$% $HR_{max}$ (exercise intensity was increased gradually), per day, $3{\sim}5$ times a weeks. The results after 12 weeks were compared to baseline values. Weight and BMI, %body fat, and fasting glucose significantly decreased, and $_{peak}VO_{2}$, exercise time (ET) significantly increased after 12 weeks of aerobic exercise training. On the other hand, there were no significant differences in hepatic enzymes of Albumin, Total bilirubin, Alkaline phosphatate, AST, and ALT after training compared to baseline values. Conclusively, 12 weeks of aerobic exercise training may result in a decrease of insulin resistance factors (Weight, BMI, % body fat, fasting glucose) and an increase of aerobic capacity, but hepatic enzymes did not significantly decrease in middle age T2DM patients.
Falls are a major sources of death and injury in elderly people. Aged-related changes in the physiological systems which contribute to the maintenance of balance are well documented in older adults. These changes coupled with age-related changes in muscle and bone are likely to contribute to an increased risk of falls in this population. Regular exercise may be one way of preventing falls and fall-related fractures. However, the optimal exercise prescription to prevent falls has not yet been defined. On the literature review of exercise intervention for fall prevention in the elderly, exercise appeared to be a useful tool in fall prevention by improving fall risk factors. The optimum exercise prescription; moderate intensity frequency of 3-4 times per week, duration of 30-60minutes can contribute to decreased hazards and number of fall. Fall prevention protocol should include safety, falling effect, enjoyment, and easiness to follow for older people. Effective exercise programs suggested for fall prevention were such as weight-bearing exercise, resistance exercise, lower muscle strength with elastic band, swiss ball exercise walking, tai chi, and yoga.
This study was designed to investigate the effect of Gibson's smile exercise. The author took the smile photographs of 35 university students who appeared unnatural smiles though they had good dentition or well restored state of their teeth. The author explained Gibson's smile exercise and they trained their perioral muscles during 4 weeks at home. The smile photographs were taken at regular intervals, before the smile exercise, 2 weeks after and 4 weeks after the smile exercise. And then, esthetic smile scores were estimated by 10 appraisers who were dentists. Some questionares were taken aftersmile exercise. And acquired scores were analized statistically using the SPSS program. The results obtained were as follows. 1. The smile scores of 2 weeks after and 4 weeks after the smile exercise were higher than before the smile exercise. 2. The smile scores of 4 weeks after the smile exercise were higher than 2 weeks after the smile exercise. 3. The smile scores of the group interested in smiles were higher than the group not interested in smiles at 2 weeks after and 4 weeks after the smile exercise, but before the smile exercise there was no difference between two groups.
The purpose of this study is to analyze the effects of exercise therapy on serum lipid levels and antioxidants of obese and normal college female students. The subject group composed of ten normal-weight students(below 30% body fat ratio) and ten obese students(above 30% body fat ratio). After a pilot test, the subjects were given an eight-weeks exercise program. Before and after the exercise program, the subjects were given test for serum lipid and antioxidants were analyzed. The SAS program was used in the data analysis. The statistical measurements employed here were T-test, Wilcoxon signed rank test, and Wilcoxon rank sum test. The results of this research are as follows. 1) The effects of exercise therapy on serum lipid levels : Before the exercise therapy, the levels of Total-cholesterol, Triglyceride and LDL-cholesterol of the obese group were highier than those of the normal-weight group. However, the HDL-cholesterol levels were highier in the normal-weight group than in the obese group, but these differences were not significant. With the exercise therapy, the levels of Total-cholesterol increased gradually. The HDL-cholesterol increased gradually, the LDL-cholesterol level decreased in both groups, However, the Triglyceride level decreased in the obese group and increased in normal group, but the difference was not significant. 2) The effects of the exercise therapy on serum antioxidants ; Before exercise therapy, the serum FR and GSSG levels of the obese group were significantly highier than those of the normal-weight group(p=0.00, p=0.04). The serum GSH level of the normal-weight group was highier than that of the obese group, and the serum MDA level of the obese group was highier than that of the normal-weight group. Again these differences were not significant. With exercise therapy, serum FR level was reduced and serum GSSG level significantly increased in both group(obese group p=0.01, normal-weight group p=0.01), The serum GSH level of the obese group significantly increased (p=0.01), and serum MDA level significantly increased in the obese group(p=0.01), but the difference in the normal-weight group was not significant. These results show that regular exercise therapy reduces serum FR levels and activation of antioxidant systems, and suppress oxidative stress. These effects were slightly highier in the obese group than in the normal-weight group. The regular exercise therapy decreased the serum Triglyceride levels more in the obese group than in the normal-weight group. However the improvement of the serum lipid profile may require a longer exercise period than eight weeks. The results show that the exercise therapy was overall more effective in the obese group than the normal-weight group.
The purpose of this study is to evaluate the different type of exercise training on the changes of blood variables and leptin in SD rats. For this study, SD rats were divided into three groups: control group (CG: n=10), swim trained group (SG: n=10), and treadmill trained group (TG: n=10). The animals were housed in a pathogen-free animal facility ($22-24^{\circ}C$, 50-60% relative humidity, 08:00-20:00 lighting hours) at D university animal center, Pusan, Korea). Food and water were available ad libitum. The trained rats underwent a 8-wk endurance swim training (5 times/wk) in water at $26-29^{\circ}C$ (SG) and treadmill training (5 times/wk) in DAEJONG treadmill for 60 min. All data were expressed as mean and standard deviation by using SPSS package program (ver 10.0). The result through the statistical analysis of this data were summarized as follows: 1. In the weight changes, there were significant differences among CG, SG and TG(p<.05) after regular swim and treadmill training. TG showed the lowest weight than the other groups. 2. In the epididymal & perirenal adipose tissue levels, there were significant differences among CG, SG and TG(p<.05) after regular swim and treadmill training. TG showed the lowest adipose tissue levels than the other groups. 3. In the triglyceride changes, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG showed the lowest triglyceride levels than the other groups. 4. In the insulin hormone, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG showed the lowest insulin levels than the other groups. 5. In the leptin changes, For the SG and TG, there were significantly decreased after regular swim and treadmill training. TG was the lowest than the other groups. Based on the results, Regular swim and treadmill training decrease body weight, epididymal & perirenal adipose tissue levels significantly, this is caused but by decreased triglycerides, insulin, and leptin hormone levels not by the other factors. Regular treadmill training decreased insulin hormone levels compare to swim training, however there was no direct insulin effect on the weight changes. and it might be the direct effect of leptin hormones.
This study was conducted to evaluate the effect of regular exercise and other relating factors on the activities of erythrocyte antioxidant enzymes and plasma total radical-trapping antioxidant potential (TRAP) in 61 healthy male college students. The study population were divided in two groups ; small amount of exerciser (exorcise time less than 30min/d) and moderate amount of exerciser (exorcise time more than 30min/d) according to their physical exercise habits measured by a questionnaire. Dietary intake of vitamin C and vitamin E, Plasma lipid Profiles, erythrocyte superoxide dismutase(SOD), glutathione peroxidase(GSH-Px) and catalase activities, as well as plasma TRAP levels were determined. Plasma TRAP level was significantly higher in moderate amount of exercisers than that in small amount of exercisers. No significant differences were observed in erythrocryte SOD, catalase and GSH-Px between the two groups. Mean exercise time was positively correlated with the plasma level of TRAP significantly, and amount of alcohol consumption was negatively correlated with the erythrocyte SOD activity, Dietary vitamin C and I intakes did not correlated with either erythrocyte enzyme activities or plasma TRAP levels. There were positive correlations between plasma HDL-cholesterol, and erythrocyte GSH-Px or plasma TRAP levels. Plasma vitamin C concentrations was negatively correlated with plasma TRAP levels and erythrocyte SOD activity, however plasma vitamin C concentration was positively correlated with erythrocyte GSH-Px activity, The results would suggest that regular moderate exercise, nonsmoking, high HDL-cholesterol and high plasma vitamin E concentration enhance antioxidant defences against reactive oxygen species and may increase the likelihood of a healthier life span.
The purpose of this study was to assess the metabolic profile and nutrient intake data in Korean adolescents according to exercise regularity using the forth Korean National Health and Nutrition Examination Survey from 2008 data. A total of 834 Korean adolescents (440 boys, 394 girls) aged 12 to 18 years were classified into exercising male (EM), non-exercising male (NM), exercising female (EF), and non-exercising female (NF) groups. EM exhibited significantly higher weight (P<0.001), waist circumference (WC) (P<0.01) and body mass index (EMI) (P<0.001) than NM. EF showed significantly greater height (P<0.01), weight (P<0.001), we (P<0.001), and BMI (P<0.001) than NF. Although ratios of macronutrient intake were within the appropriate range in all groups, energy, riboflavin, vitamin e and calcium were assessed as in adequate by the nutritional adequacy ratio (NAR) in all groups. Moreover, EF and NF had inadequate intake of vitamin A and iron according to NAR, respectively. There were significant correlations between height and NAR protein (r=0.249, P<0.001), and mean adequacy ratio (MAR) (r=0.177, P<0.01), and between weight and NAR protein (r=0.180, P<0.01), and MAR(r=0.136, P<0.05) in EM. On the other hand, there were significant correlations between weight and NAR protein (r=0.270, P<0.01), we and NAR protein (r=0.271, P<0.01), and BMI and NAR protein (r=0.326, P<0.01) in NM. There were significant correlations height and NAR Fe (r=0.153, P<0.05) in EF. However, there were no significant correlations between metabolic factors and nutritional adequacy in NF. Although we noted no significant differences in MAR between the groups, the exercising groups showed higher MAR values than the non-exercising groups. Therefore, practicing of ideal dietary behaviors appears to be induced through physical activity and regular exercise in Korean adolescents.
