  • Objectives: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. Methods: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. Results: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. Conclusion: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.

  • This study was done to determine the effect of music therapy on stress and quality of life in patients undergoing hemodialysis. The research design was a nonequivalent control group pre -post test design. The subjects consisted of 21 patients who received hemodialysis in two hospitals located in Kwang Ju. The fourteen receiving treatment in one hospital were assigned to the experimental group and the seven in the other hospital to the control group. Data were gathered from December 14, 1992 to January 16, 1993 through questionnaires and physiological measurement. Data were analyzed by the SAS package using frequency, t-test, paired t-test and Pearson Prod uct - Moment Correlation Coefficient. The results of this study are summarized as follows ; 1. There were no significant differences between the two groups on stress scores and quality of life scores before the treatment. 2. The mean score on the psychological stress scale for the patients undergoing hemodialysis was 2.48 out of a maximum mean score of four, the items with high stress scores were “feeling of weakness and annoyed by everything”, “limitation of food”, “limitation of fluid”, “change in skin color” in that order. The psychological category showed the highest stress score followed by developmental, scoioeconomic and physiological stress categories in that order. 3. In the experimental group, post - test diastolic blood pressure decerased significantly(t=3.24, p=0.0064), but in the control group pre and post - test diastolic blood pressure were not different. 4. There was no difference between the two groups on the pre and post -test psychological stress scores or the depression scores. 5. The mean score of quality of life for patients undergoing hemodialysis was 2.75 out of a maxi-mum mean score of five. The category of ‘emtional state’ showed the highest score followed by ‘self - esteem’, ‘physical state and function’, ‘economic life’, ‘relationship with neighbors’ and ‘family relationship’ categories in that order. There was no significant difference in the pre and post - test quality of life scores between the two groups. 6. Hypothesis 1 that patients undergoing hemodialysis who received music therapy would have less stress than patients undergoing hemodialysis who did not receive music therapy is divided into two sub - hypotheses. 1) The first sub-hypothesis that patients undergoing hemodialysis who received music therapy would have less physiological stress than patients undergoing hemodialysis who did not receive music therapy was partly supported. Among three physiological stress indices (pulse, systolic blood pressure, diastolic blood pressure), only diastolic blood pressure decreased significantly after the treatment in the experimental group. 2) The second sub-hypothesis that patients undergoing hemodialysis who received music therapy would have less psychological stress than patients undergoing hemodialysis who did not receive music therapy was not supported. Psychological stress score and depression score were not significantly different before and after the treatment. 7. Hypothesis 2 that patients undergoing hemodialysis who received music therapy would have a higher quality of life score than patients undergoing. hemodialysis who did not received music therapy was not supported. There were no significant changes in the quality of life scores before and after the treatment.

  • Background: Metabolic syndrome (MS) is a cluster of complicated disorders caused by the interactive influencing factors of heredity and environment, which predisposes to many cnacers. Results from epidemic research indicate that stress is tightly related to the pathogenesis of MS and neoplasia. This paper aims to investigate the association between psychological stress and MS with respect to the tumor necrosis factor alpha (TNF${\alpha}$) and neuropeptide Y (NPY) genes in the Han and Hui ethnic groups. Methods: All subjects for this case-control study matched strict enrollment criteria (nationality, gender and age) and lived in the city of Wu Zhong of Ningxia Province in China. The enrolled group contained 102 matched pairs of Hui ethnic individuals and 98 matched pairs of Han ethnic individuals. Enrolled subjects completed the general Symptom Checklist-90 (SCL-90). The TNF${\alpha}$-308G/A variant and NPYrs16147 polymorphism were detected in case (81 males, 119 females) and control (81 males, 119 females) groups by polymerase chain reaction (PCR) amplification. Results: Nine factors of the SCL-90 were found to be statistically different (p<0.05) between case and control groups. The homozygous mutant genotype (AA) and the mutant allele (A) of the TNF${\alpha}$-308G/A gene were less frequently observed in the control population compared to the case group. The odds ratio (95% confidence interval) in "Allele" for MS was 2.28 (1.47-3.53), p=0.0001, while "OR" was 1.11 (0.83-1.47), p=0.15, for the NPYrs16147 gene polymorphism. Conclusions: Psychological stress has been positively associated with MS. A previous study from our group suggested there were differences in the level of psychological stress between Hui and Han ethnic groups. Furthermore, we found that the stress-related TNF${\alpha}$ gene was associated with MS for both Han and Hui ethnic groups. In contrast, NPY may be a possible contributor to MS and associated cancer for the Han ethnic group.

  • Purpose: The purpose of this study was to investigate factors related to obesity of mid-age women and to examine the relationship between obesity and chronic diseases including diabetes, hypertension, and heart disease. Methods: Using data from Korean American adults living in California, we analyzed the health behavior (diet, exercise, smoking, and binge drinking) and psychological stress of obese women with body mass index ${\geq}25$ by using chi-square test. Logistic regression was used to investigate independent effects of obesity on chronic diseases, after controlling for risk factors. Results: The prevalence of obesity appeared about 16.9%. The Obese group was less likely than the non-obese group to eat vegetables and more likely feel psychological stress. There were no significant differences in smoking, alcohol intake, and physical exercise between the two groups. Obesity was strongly related to chronic diseases (OR=4.642, 95% CI=1.328-16.222). Conclusion: This study suggests that obesity of mid-age women could be reduced by encouraging health behavior such as eating vegetables daily, performing physical exercise regularly, and taking care of emotional stress. Diet and physical activity interventions and emotional supports should be developed for weight loss and prevention of weight gain in mid-age women.

  • Objectives : The study is performed to investigate the influence of psychological stress on neck muscles tone and heart rate variability(HRV). Methods : This study was carried out with the data from stress response index score(SRI), surface electromyography(sEMG) and HRV. First subjects were divided into two group according to the SRI points. Subjects in group A had points of SRI in which lower than 30 points. Subjects in group B had points of SRI in which higher than 30 points. Then we investigated how to difference of the index of sEMG and HRV according to each groups. Results : In this study, the muscle contraction of both upper trapezius muscle in stress group were higher than non-stress group significantly. Complexity, root mean square of successive differences of R-R intervals(RMSSD), standard deviation difference between adjacent normal to normal intervals(SDSD), high frequency oscillation power(Ln(HF)), normalized HF(Norm HF) in stress group were lower than non-stress group significantly and normalized LF(Norm LF) was higher. Conclusions : This results show that the stress was associated with neck muscle condition and autonomic nervous system.

  • Purpose: This study was conducted to examine the relationship between stress and quality of life of family caregivers of patients with lung cancer. Methods: From April 18 to May 4, 2009, data were collected using self-report questionnaires with 95 family caregivers of lung cancer patients in G cancer center. The data were analyzed using descriptive statistics, t-test, ANOVA and pearson's correlation coefficient with SPSS 14.0. Results: The mean score of the stress level was 27.5 (SD=14.77). The mean score of the QOL was 73.0 (SD=17.86). The stress level of family caregiver showed significant difference according to gender (psychological stress p=.011, total level of stress p=.042) and availableness of second caregiver (physical stress p=.023, psychological stress p=.035, total level of stress p=.001). The QOL of family caregivers showed significant difference according to daily caring (positive adaptation p=.045) and financial burden on treatment expense (positive adaptation p=.004, total quality of life p=.043). The negative correlation was found between stress and QOL of family caregivers (r=-.67, p=.032). Conclusion: These results indicate a need to develop nursing intervention programs for family caregivers to reduce stress and improve QOL.

  • Purpose: The aim of this study was to examine the effects of a yoga program on perceived stress, stress response and heart rate variability in professionals. Methods: The research design was a quasi-experimental intervention study. The participants were 47 adults with professional jobs consisting of an experimental group with 23 adults and a control group with 24 adults. The duration of the yoga program was eight weeks from July 4 to August 30, 2012. Results: There were significant decreases in the stress response score after the yoga program. No significant changes in perceived stress and heart rate variability were observed between the experimental group and control group. However, there were significant decreases in perceived stress, stress response scale, and heart rate variability for some participants whose stress levels were high. Conclusion: An eight-week-long yoga program could be considered as an intervention to decrease the stress response of professionals even though it might not reduce their perceived stress and heart rate variability. To further analyze the effects of a yoga program in professionals, changes in intervention strength (such as longer periods and frequency) and the development of physiological measures, which would show the co-relationship between perceived stress and physiological response, are necessary in future studies.

  • The effects of anti-stress chrysanthemum flower (ASCF) extract drink (ASCF-0.1% and ASCF-0.5% concentrations) were tested for the anti-stress action. ICR male mice (20$\pm$2 g) were fed with basic experimental diets and given free access to water containing these ingredients for 18 days. Psychological stress/sociopsychologcal stress exposed by foot-shock for 1 hour for 3 days. Both ASCF-0.1 and ASCF-0.5 groups in the sociopsychological stress resulted in a significant decrease of 28.1% and 27.3% in plasma corticosterone (CS) secretion compared with psychological stress (control group). Noradrenaline (NA) secretions in the brain were significantly increased 49.7% and 53.9%, respectively, in ASCF-0.1 and ASCF-0.5 groups compared with control group. MHPG-SO4 (3-Methoxy-4-hydroxyphenylethy-leneglycol sulfate) levels in the brain resulted in a marked decreases of 12.9% and 16.6%, respectively in ASCF-0.1 and ASCF-0.5 groups. NA/MHPG-SO4 ratios in the brain of ASCF-0.1 and ASCF-0.5 groups resulted in a significantly increase of 71.3% and 81.0%, respectively, compared with control group. These results suggest that anti-stress chrysanthemum flower (ASCF) drink can effectively ridded the sociopsychological stress.
