This study was to investigate the level of fatigue and its associated variables in patients with systemic lupus erythematosus(SLE) in Korea. From March to June, 2001, 100 patients, registered at one university hospital rheumatology clinic in Seoul, were accepted as subjects for this study. The sampling method was adopted a non-probability, purposive technique. The instruments used for this study were The Multidimensional Assessment Fatigue scale developed by Tack and Beck Depression Instrument develped by Beck. The collected data were analyzed by SAS program using t-test, ANOVA with Scheffe-test, Pearson correlation coefficients and stepwise multiple regression. The results were as follows: 1. Total scores of fatigue of the subjects averaged $24.46(\pm10.85)$, degree of fatigue was $5.08(\pm2.29)$, and influence of fatigue was $3.52(\pm2.12)$. 2. Regarding characteristics, more depressive(p=.0001) and more painfuI(p=.0122) patients revealed more fatigue. Also, the subjects with spouse(p=.0337) and having poor quality of sleep(p=.0445) revealed more fatigue. 3. The subjects' total fatigue score, depression, pain and age was correlated positively(r=.53; r=.48; r=.24), and total fatigue score, and exercise time, quality of sleep was correlated negatively(r=-.45; r=-.21). 4. The main influencing factors on the fatigue were depression$(52.92\%)$ and quality of sleep $(8.10\%)$. These two main variables made it possible to explain $61.02\%$ of the varience in fatigue. In conclusion, this study revealed depression and quality of sleep is an important factor that can improve quality of life in patients with SLE. It is recommended that nursing intervention for SLE patients would be focused to decrease depression and to enhance quality of sleep.

This study was undertaken to investigate the relationship between the life style and the nutritional status of serum antioxidant vitamins and lipids in university male and female students. 48 male and 49 female students attending Andong university, aged between 18 and 25 years, were selected. Questions about the life styles including dietary intakes, food habits, smoking, drinking alcohol, exercise, stress were answered. And serum levels of antioxidant vitamins and lipids were determined. Average serum levels of total cholesterol, LDL C, HDL C, and triglyceride in male and female subjects were 158.6$\pm$32.7, 177.3$\pm$33.8; 86.4$\pm$26.0, 109.0$\pm$31.2; 46.0$\pm$10.7, 49.9$\pm$12.4; 131.2$\pm$22.5, 91.7$\pm$ 38.6mg/dl respectively. Average serum levels of antioxidant vitamin A, E and C in male and female subjects were 42.6$\pm$12.3, 31.4$\pm$9.8 g/dl, 1.11$\pm$0.38, 1.15$\pm$0.29mg/dl and 164.66 $\pm$65.01, 220.06$\pm$80.11 g/dl respectively. There was no significant difference between smoking habits and either serum lipids or antioxidant vitamins level. The serum vitamin C level of drinkers was significantly lower(p=0.038), but serum lipids(total cholesterol, LDL C, and triglyceride) were higher than non alcoholic subjects. The subjects with severe stress had lower in HDL C and higher in atherogenic index than others. This result indicates that oxidative stress may be increased in stressful environment from undesirable life styles and influence the status of serum lipid and antioxidant vitamins.

Background: To improve lumbo-pelvic stability, passive support devices (i.e., a pelvic belt) are recommended clinically. Nevertheless, to understand the influence of passive support on lumbo-pelvic stability, it is necessary to examine the influence of a pelvic belt on the abdominal and hip abductor muscles. Objects: To examine the effects of a pelvic belt on the forces of the hip adductor and abductor muscles and activity of the abdominal muscles during isometric hip adduction and abduction. Methods: This study recruited 14 healthy men. All subjects performed isometric hip adduction and abduction with and without a pelvic belt in a neutral hip position. Load cells, wrapped with a non-elastic belt, were placed above the medial and lateral malleoli of the dominant leg to measure the muscle forces of the hip adductors and abductors, respectively. The forces of the hip adductors and abductors were measured using a load cell during isometric hip adduction and abduction, while the electromyographic activities of the bilateral rectus abdominis, internal oblique, and external oblique muscles were measured. Results: The forces generated by the hip adductors and abductors were significantly greater with the pelvic belt than without (p<.05). No significant differences in abdominal muscle activities between the two conditions were found (p>.05). Conclusion: These findings suggest that use of a pelvic belt could lead to effective strengthening exercise of hip muscles in individuals with sacroiliac joint pain.

This study analyzes the effects of caring for grandchildren on Korean grandparents' health, using the Korean Longitudinal Study of Aging from 2006 to 2012. We investigate how caregiving is provided and analyze the effects of caregiving on grandparents' physical health, mental health, and health-related behaviors. As elderly people's health is generally frail, it is unclear whether the provision of childcare affects their health negatively. We control for the endogeneity of caregiving by an individual fixed effect (FE) model and instrumental variable-fixed effect (FE-IV) models. Using these models, we determine the endogeneity of caregiving and show that the significant effects of caregiving on health disappear as we control for endogeneity in the FE and FE-IV models. Even after controlling for endogeneity, we find that caregiving increases the probability of feeling pain as well as the number of different types of pain. Furthermore, caregiving increases the probability of restrictions on daily activities because of pain. On the other hand, caregiving reduces the symptoms of depression. In relation to health-related behaviors, caregiving reduces the probability of physical exercise and regular meals. Our results imply that although caregiving has a positive effect on mental health, the increase in physical pain and in non-healthy behaviors may lead to a deterioration of the caregiver's long-term health, which in turn may increase the medical costs of the elderly. Potential policy alternatives are discussed in the paper.

Purpose: The aim of this study was to examine the effects of obesity on the physiological levels of adiponectin, leptin and components of metabolic syndrome (MS) in male workers, aged 30-40 years. Methods: Body mass index (BMI) was measured with Anthropometric equipment. Blood pressure and serum parameters were measured with an automatic digital sphygmomanometer and autochemical analyzer, respectively. Adiponectin and leptin were analysed by ELISA kits and MS was defined based on the NCEP-ATP III. Results: Body fat mass of waist and hip, systolic and diastolic blood pressure were significantly higher, as expected, in the BMI>25kg/$m^2$ in comparison with the $BMI{\leq}25kg/m^2$. While fasting glucose, insulin, HOMA-IR and leptin in the BMI>25kg/$m^2$ were also significantly higher compared with $BMI{\leq}25kg/m^2$, HDL-cholesterol and adiponectin were significantly higher in $BMI{\leq}25kg/m^2$. On multiple logistic regression analysis for the components of MS, exercise, adiponectin and leptin were an only independent factor for MS in non-obese male workers($BMI{\leq}25kg/m^2$) after adjustment for age, cigarette smoking and drinking habits. Conclusion: These results suggested that the obesity in men was associated with physiological levels of adiponectin and leptin contributing to feedback control of MS and that dysfunction and/or declination in feedback control system associated with changes in physiological levels of neurptrophics: adiponectin and leptin might ultimately induce MS.

Purpose: This study was attempted to see the trends in breast cancer researches in Korea. Method: We collected a total of 94 articles associated with breast cancer and published in Korea from 1976 to August 2004 and analyzed the characteristics of those articles, the journals which published those articles in each year, the research designs, subjects, intervention effects in experimental studies, the subjects and concept distribution in comparative researches and themes of the articles. Result: 1. Articles published and associated with breast cancer have increased since 1990 and picked after 2000. 2. Most research designs are survey and correlation studies which are non-experimental research(70.2%) and next are experimental and qualitative researches. 3. In a total 17 articles which are experimental researches, intervention studies which use exercise programs are most(5 articles) and the next are education program, supportive nursing intervention, guided imagery, massage and rehabilitation programs. 4. In correlational researches, concepts such like social-psychological adaptation, partner support, health promotion behavior and family support are treated frequently. 5. Subjects in most comparative studies are patients with breast cancer and normal women. 6. Most nursing research themes are psycho/spiritual problems, 16 articles(17.0%). Conclusion: These results show that the researches related with breast cancer have actively increased and body functions and psycho-social variables have been improved through nursing intervention. Therefore, it seems that more systematic interdisciplinary studies and systematic complement are necessary for future breast cancer nursing researches.

Heart rate recovery (HRR) is simply an indicator of autonomic balance and is a useful physiological indicator to predict cardiovascular morbidity and mortality. The purpose of this study was to compare the differences in HRR between metabolically healthy obesity group and metabolically unhealthy obesity and to ascertain whether heart rate recovery is a predictor of metabolic syndrome. Metabolic syndrome was defined according to the standards of the National Cholesterol Education Program Adult Care Panel III. Obesity was assessed according to WHO Asian criteria. It was classified into three groups of metabolically healthy non-obesity group (MHNO, n=113), metabolically healthy obesity group (MHO, n=66), metabolically unhealthy obesity (MUO, n=18). Exercise test was performed with Bruce protocol using a treadmill instrument. There was no difference in HRR between MHO and MUO ($32.71{\pm}12.25$ vs $25.53{\pm}8.13$), but there was late HRR in MUO than MHNO ($25.53{\pm}8.13$ vs $34.51{\pm}11.80$). HRR in obese was significantly correlated with BMI (r=-0.342, P=0.004), waist circumference (r=-0.246, P=0.043), triglyceride (r=-0.350, P=0.003), HbA1c (r=-0.315, P=0.009), insulin (r=-0.290, P=0.017) and uric acid (r=-0.303, P=0.012). HRR showed a lower prevalence of abdominal obesity, hypertriglyceridemia, and low HDL-cholesterol in the third tertile than in the first tertile. In conclusion, MHO had no difference in vagal activity compared with MHNO, but MUO had low vagal activity. HRR is associated with metabolic parameters and is a useful predictor of abdominal obesity, hypertriglyceridemia, and low HDL-cholesterolemia.

Background. Ischemic heart disease results from athesclerotic changes of the coronary artery. These changes are aggravated by hypercholesterolemia, smoking, obesity, lack of exercise, coronary-prone personality, and stress. Because these risk factors affect not only the prevalence of the ischemic heart disease but also recurrence of the disease, cardiac rehabilitation programs were introduced to help patients with ischemic heart disease reduce risk factors. Diverse cardiac rehabilitation programs are needed to motivate participation in cardiac rehabilitation and to enhance patients' quality of life. Objectives. To examine the effect of a self-efficacy promoting cardiac rehabiltation program on self-efficacy, health behavior and quality of life of patients with ischemic heart disease. Methods. Data were collected from 45 hospitalized ischemic heart disease patients. Medical records were reviewed to obtain demographic and clinical characteristics. Data regarding self-efficacy, health behavior, and quality of life were obtained from interviews using structured questionnaires. The nonequivalent control group non-synchronized design was used to conduct this study. One session of conventional group education was given to patients in the control group while they were in the hospital. Patients in the experimental group participated in a newly developed cardiac rehabilitation program. It focused on strengthening self-efficacy with four self-efficacy sources-performance accomplishment, vicarious experiences, verbal persuasion and physical status using two individualized in-hospital education sessions and four weekly telephone counseling follow-up calls after discharge. Results. Four weeks after discharge, the increment of total self-efficacy score was significantly higher in the experimental group than in the control group (p<.0l). There was also a significant difference in the total quality of life scores increments between the two groups (p<.0l). However, no significant changes were noted in the increments of total health behavior scores between the two groups. Conclusion. A cardiac rehabilitation program focusing on promoting self-efficacy was effective in improving self-efficacy, and quality of life of patients with ischemic heart disease.
