Impact of Co-occurring Dysarthria and Aphasia on Functional Recovery in Post-stroke Patients

OBJECTIVE: To elucidate the impact of co-occurring dysarthria and aphasia on functional recovery in post-stroke patients. METHODS: The medical records, including results of primary screening tests and secondary definite examinations for language problems, of 130 patients admitted to our institute's Department of Rehabilitation Medicine were retrospectively reviewed. Functional outcomes were assessed longitudinally using the Functional Ambulation Category (FAC), Mini-Mental State Examination-Korean version (MMSE-K), European Quality of Life-5 Dimensions 3-Level version (EQ-5D-3L), the Korean version of the Modified Barthel index (K-MBI), and Motricity Index (MI) of the hemiplegic side. RESULTS: Patients were classified into four groups regarding language function: aphasia only (group A, n=9), dysarthria only (group D, n=12), aphasia and dysarthria (group AD, n=46), and none (group N, n=55). The initial functional outcome scores in the group AD were significantly poor compared to those of the groups N and A. Within groups, there were significant improvements in all outcome measurements in the groups AD and N. A between-group analysis revealed significant improvements in K-MBI for the group AD after adjusting for the initial severity and patient's age compared to other groups. CONCLUSION: Post-stroke patients suffering from aphasia with dysarthria showed significantly lower initial functional level and relatively wide range of recovery potential in activities of daily living compared to patients without language problems.

HIV-1 Tat Protein Promotes Amyloid beta Generation and Tau Phosphorylation in Rat Hippocampal Slices

HIV-1 Tat protein has been implicated as a causative agent in the pathogenesis of HIV-1-associated neurocognitive disorder (HAND) and Alzheimer's disease (AD)-like pathology in HIV-1 infected patients. Here, we provide insights into the potential roles of extracellular HIV-1 Tat protein in amyloid beta (Abeta) generation and Tau phosphorylation, two major neuropathological features of AD. Exposure of the rat hippocampal slices to the full-length HIV-1 Tat protein (Tat1-86) for 3 days led to the increased levels of Abeta precursor protein (APP) accumulation, which accompanied by Abeta generation in the hippocampus, the brain region most commonly damaged in HIV-1-associated dementia (HAD). Moreover, extracellular HIV-1 Tat significantly stimulated the level of phosphrylated Tau (pTau) identified using immunoblotting with AT8 antibody, which recognizes abnormally hyperphosphorylated Tau. Collectively, our data suggest that HIV-1 Tat plays important roles in increasing the levels of APP accumulation, Abeta generation and Tau phosphorylation in the hippocampus, and thereby might contribute to the development of AD-like pathology in HIV-1-infected patients.

HIV-1 Tat Protein-dependent Cytotoxicity is Attenated by 15-deoxy-Delta12,14-Prostaglandin J2 in Rat Hippocampal Slices: Involvement of the ERK1/2 Signaling Pathway

15-deoxy-delta12,14 prostaglandin J2 (15d-PGJ2) may hold promise in treatment of the pathologies associated with human immunodeficiency virus (HIV) infection of the central nervous system. However, its precise role and neuroprotective mechanism in the hippocampus remain poorly understood. In the present study, rat hippocampal slices were stimulated with HIV-1 Tat protein to investigate the protective role of 15d-PGJ2 on the hippocampal cytotoxicity. Full-length HIV-1 Tat protein (Tat1-86), but neither its Tat32-62 nor Tat30-86 fragment, significantly induced cytotoxicity in the hippocampus, the brain region most commonly damaged in HIV-associated dementia. This Tat-induced cytotoxicity was associated with inactivation of MEK/extracellular signal-regulated kinase (ERK) signaling pathway. In contrast, Tat1-86 did not alter Wnt signaling pathway necessary for cell survival. Pretreatment of slices with 15d-PGJ2 markedly reduced Tat-driven cytotxicity. Interestingly, this reduction was accompanied by suppression of ERK inactivation in response to Tat. Moreover, the inhibition of the MEK/ERK pathway with SL327 enhanced the Tat-induced cytotoxicity, confirming the ERK-dependent mechanism of Tat-driven cytotoxicity. Collectively, these data demonstrate that the protective action of 15d-PGJ2 against the hippocampal cytotoxicity upon Tat stimulation is exerted through suppression of Tat-mediated ERK1/2 inactivation.

Escherichia coli pap Genes as well as Adenovirus Type 11 and Type 21, and BK Virus were Involved with Severe Urinary Tract Infection in Infants

In infants, urinary tract infections (UTIs) are quite common and primarily caused by bacterial pathogens. However, little research has been conducted regarding the relationship between uropathogenic bacteria, virulent genes, and uropathogenic viruses that might induce UTIs in infants. In this study, we evaluated infants with UTIs to determine the influence of bacterial virulent genes and type of viral infections on clinical aspects. First, we detected 44 cases of bacterial UTI from 600 suspected cases in infants and children. We detected E. coli urovirulence genes (kps, usp, pap, ireA, and cnf), two enteropathogenic E. coli genes (bfpA, and eae) and four S. aureus and S. epidermidis genes (mecA, pvl, bbp, and icaA) in urine samples from infant UTI cases. We also simultaneously detected hematuria-related adenovirus type 11, 21, and BK virus (BKV) in urine samples by PCR. As a result, E. coli was the most prevalent bacteria and in Dimercaptosuccinic acid (DMSA)-positive UTI cases, the uropathogenic E. coli virulence factor pap was significantly high. We found that BKV detection was significantly higher in DMSA-positive UTI infants (89%) compared with 50% of non-UTI (no bacteria detected) cases. These results are indicative of combined multiple bacterial and viral infections and show severe infant pyelonephritis.

Effects of Tai Chi or Self-help Program on Balance, Flexibility, Oxygen Consumption, and Muscle Strength in Women with Osteoarthritis / 기본간호학회지

PURPOSE: This randomized study was done to compare the effects of a 6 month Tai Chi exercise and a self-help program on balance, flexibility and muscle strength in women with osteoarthritis (OA). METHOD: In this experimental study, 82 women with OA recruited from outpatient clinics or community health centers were randomly assigned either to a Tai Chi group or a self-help group. Thirty women (mean age = 62 years) in the Tai Chi group and 39 (mean age = 59 years) in the self-help group completed posttest measures (balance, flexibility, oxygen consumption, abdominal muscle strength, back muscle strength, and grip strength) at 6 months. RESULTS: After the 6 month, Tai Chi participants had significantly greater balance (mean difference = 2.9 vs. 0.9 for the self-help), grip strength (mean difference = 4.6 vs. 0.9 for the self-help), and back muscle strength (mean difference = 4.1 vs. -0.3 for the self-help). However, flexibility, oxygen consumption, and abdominal muscle strength were not significantly different between the groups. CONCLUSION: Tai Chi increased balance, grip strength and back muscle strength in older women with osteoarthritis compared to the self-help program. Whether these changes improve physical functioning and fall prevention requires further study.

Factors Influencing Quality of Life in Patients with Gastrointestinal Neoplasms

PURPOSE: The purpose of this study was to identify the factors influencing quality of life after analyzing the relationship between depression, health promotion and quality of life in patients with gastrointestinal neoplasms. METHODS: The subjects of this study were 63 people who underwent treatments from 2 general hospitals in Seoul and Daejeon and had no recurrence in stages I & II of gastrointestinal neoplasms. Data was collected from March 1 to April 30, 2006. A questionnaire consisting of Center for Epidemiologic Studies Depression (CES-D), Health Promoting Lifestyle Profile II (HPLP II) and Functional Assessment of Cancer Therapy-Colorectal (FACT-C) was given. The collected data was analyzed with the SPSS program which was used for descriptive statistics, Pearson correlation coefficients and hierarchical multiple regression. RESULTS: The major findings of this study were as follows: 1) There was a significant relationship between depression (r=-.639, p=.000), health promotion (r=.407, p=.001) and quality of life. 2) Significant factors were depression (F=-4.091, p=.000) and health promotion (F=2.375, p=.021) that explained 46% of quality of life (F=10.022, p=.000). CONCLUSION: Cancer patients experienced extreme depression which led to a negative effect on quality of life. Health promotion was an important variable to the quality of life and it gave the patients motivation for having a will and belief for better health.

Detection of Virulence Genes of Staphyloccus aureus and Staphylococcus epidermidis Isolated from Suprapubic Urine from Infants with Fever

While methicillin-resistant Staphylococcus aureus (MRSA) isolated from urinary tract infection (UTI) has recently increased in elderly adult urology patients, it has been only rarely reported in infants. Therefore, in this study to understand whether MRSA may be involved in UTI of infants who run fever without other apparent causes, we identified and counted S. aureus and S. epidermidis in suprapubic urine from 750 febrile infants via microbiological methods, and confirmed the counts via multiplex PCR. And we also detected four virulence genes, mecA, PVL, bbp and icaA genes for S. aureus and S. epidermidis via multiplex PCR in the same specimens. S. aureus (28 cases) counts were as follows: >10(4) CFU/ml (3/28), 10(2)~10(3) CFU/ml (1/28) and 10(4) CFU/ml (2/26), 10(2)~10(3) CFU/ml (4/26) and 10(2)~10(3) CFU/ml (20/26). S. aureus virulence genes were detected in 26 cases as mecA (16/26, 59.3%), PVL (17/26, 63.0%), bbp (7/26, 26.9%) and icaA (20/26, 76.9%). S. epidermidis virulence genes were detected in 22 cases as mecA (17/22, 81.0%), PVL (15/22, 71.4%), bbp (3/22, 13.6%) and icaA (13/22, 50.1%). Therefore, mecA, PVL and icaA genes of MRSA and MRSE were detected with high positivity in urines from infants with fever. The results demonstrate that community-acquired MRSA or MRSE may be responsible for UTI incidence in febrile infants.

Effects of a Sun-style Tai Chi Exercise on Arthritic Symptoms, Motivation and the Performance of Health Behaviors in Women with Osteoarthritis / 간호학회지

PURPOSE: Tai Chi exercise, an ancient Chinese martial art, has drawn more and more attention for its health benefits. The purpose of the study was to identify the effects of a Sun-style Tai Chi exercise on arthritic symptoms (joint pain and stiffness), motivation for performing health behaviors, and the performance of health behaviors among older women with osteoarthritis. METHODS: Total of 72 women with the mean age of 63 years old were recruited from outpatients clinic or public health centers according to the inclusion criteria and assigned randomly to either the Tai Chi exercise group or the control. A Sun-style Tai Chi exercise has been provided three times a week for the first two weeks, and then once a week for another 10 weeks. In 12 weeks of study period, 22 subjects in the Tai Chi exercise group and 21 subjects in the control group completed the posttest measure with the dropout rate of 41%. Outcome variables included arthritic symptoms measured by K-WOMAC, motivation for health behavior, and health behaviors. RESULTS: At the completion of the 12 week Tai Chi exercise, the Tai Chi group perceived significantly less joint pain (t=-2.19, p=0.03) and stiffness (t=-2.24, p=0.03), perceived more health benefits (t=2.67, p=0.01), and performed better health behaviors (t=2.35, p=0.02), specifically for diet behavior (t=2.06, p=0.04) and stress management (t=2.97, p=0.005). CONCLUSION: A Sun-style Tai Chi exercise was found as beneficial for women with osteoarthritis to reduce their perceived arthritic symptoms, improve their perception of health benefits to perform better health behaviors.

Spectrin Cleavage Induced by LLP-1 Lentivirus Lytic Peptide Domain in the Intracytoplasmic Tail of Human Immunodeficiency Virus Type 1 GP41 in Rat Organotypic Hippocampal Slice Cultures

We previously demonstrated that the lentivirus lytic peptide 1 (LLP-1) corresponding to the carboxyl terminus of HIV-1 gp41 induced cell death in human neuronal cells. Present study was conducted to further elucidate the pathogenic mechanisms involved in HIV-1 gp41-induced neurodegeneration in AIDS patients with cognitive deficits. The effect of LLP-1 on activation of calpain-1, a calcium-activated cysteine protease, which has been implicated in neuronal degeneration and death, was monitored by the proteolysis of spectrin in rat organotypic hippocampal slice cultures. Protease specific spectrin breakdown products revealed that LLP-1 generated~150/145-kDa fragments characteristic of calpain-1 activation in hippocampus undergoing cell death as evidenced by LDH release. This spectrin cleavage pattern was further confirmed by in vitro calpain-1 proteolysis. Futhermore, calpectin and MDL28170, inhibitors of calpain activity, blocked calpain-1-mediated spectrin cleavage. Spectrin cleavage likely occurred in the absence of overt synaptic loss, as suggested by the preserved levels of synaptophysin. Among pharmacological agents tested, apocynin, NADPH oxidase inhibitor, ameliorated the LLP-1-induced spectrin. Given the role of spectrin essential for synapse stabilization, LLP-1-induced spectrin cleavage as occurs with the activation of calpain-1 may be an important effector in LLP-1mediated cell injury in hippocampus, which is primarily linked to cognitive dysfunction.

Development and Usability Test of a Website for Cancer Symptom Management / 대한의료정보학회지

OBJECTIVE: This study was conducted to develop cancer patients' symptom management guideline, and to develop and test the utility of the web-based guideline service system. METHODS: Based on the literature review, guidelines for symptom management for nausea/vomiting, fatigue, constipation, diarrhea, and oral mucositis were developed. A web-based cancer patients' symptom management system was developed on the basis of guideline developed in the first stage of the study. Forty-five oncology nurses were recruited and asked to evaluate and validate the system by rating level of satisfaction with function, content and effectiveness of the web-based service after they used the website for cancer patients care. RESULTS: Regarding the function of the system around 50% of oncology nurses expressed satisfaction with the system. Regarding the content of the system, nurses expressed highest satisfaction with reliability of information(66.7%) and lowest satisfaction with sufficiency of information (37.7%). Regarding the effectiveness of the system in terms of knowledge enhancement, about 40% of nurses indicated that they satisfied with the system. In terms of usefulness of the system, 48.9% of nurses expressed their satisfaction with the system. CONCLUSION: The result of this study has implications on future use of a web-based guideline for managing symptoms of cancer patients.

Development and Evaluation of Symptom Management Guidelines for Cancer Patients / 성인간호학회지

This study was conducted to develop and evaluate guidelines for cancer patients' symptoms management such as nausea/vomiting, fatigue, constipation, diarrhea, and oral mucositis. Based on the literature review, assessment path to identify each stage of five symptoms were also developed. Guidelines for symptom management of each stage of the symptoms were developed. Guidelines then were evaluated by a panel of experts. Finally, 95 cancer patients were recruited and asked to use the guidelines for their symptom management Levels of understanding of and satisfaction with assessment path and management guidelines were surveyed. Prevalence rate of five symptoms varied ranging from 20% (diarrhea) to 47% (nausea/vomiting). Regarding the level of understanding of each symptom most of the cancer patients indicated that they were easy and sufficient. Regarding the easiness of use of the symptom management guidelines, most of cancer patients indicated that they were easy to use. Regarding the nursing intervention on each symptom, most of cancer patients indicated that they were easy and helpful. More information was added with feedback from the patients. The result of this study has implications on development of customized patient education materials based on assessment path and symptom management guidelines.

The Effects of Rhythmic Walking Exercise on Physical Strength, Fatigue, and Functional Status of Breast Cancer Patients in Adjutant Chemotherapy / 성인간호학회지

Fatigue is regarded as a universal and unavoidable side effects of chemotherapy. Most of patients in chemotherapy prefer resting and reducing their level of activity, but reduced physical activity can actually decrease physical strength and functional status to produce secondary fatigue. The purpose of this study was to determine the effects of rhythmic walking exercise on physical strength, fatigue, and functional status of breast cancer patients in adjutant chemotherapy. A matched control group pretest-pottiest design was used. Seventeen subjects of the experimental group were taught the rhythmic walking exercise(Winningham etal, 1990) on their first visiting day and encouraged to practice it at home throughout that treatment cycle(four weeks). Participants kept an everyday exercise diary that included pulse rates, exercise time and subjective data. The rhythmic walking exercise consists of approximately 30-minute walking, everyday if possible for 4 weeks. Outcomes were measured by each instrument :1) physical strength by the treadmill test estimated the walking ability. The subject is instructed to walk as long as possible to the level of their tolerance ;2)functional status by the Inventory of Functional Status-Cancer(Tollman et al, 1991) ; and 3)fatigue was measured by the Piper Fatigue Scale in both groups at five different times-before beginning chemotherapy(pretest) and one time per week for 4 weeks. Data were analyzed with mean, standard deviation, X2-test, t-test, repeated measure MANOVA using SPSSWIN program. Results were obtained as follows :1)The physical strength of the experimental group was significantly higher than that of the control group following the rhythmic walking exercise(t=3.92, p<.001). 2)The fatigue scores of the experimental group measured at the end of each week were significantly lower than those of the control group following the rhythmic walking exercise (1st week ; F=6.51, p<.016, after 1st week ; 863, p<.0001, after 2nd week ; F=46.754, p<.0001, after 3rd week ; F=60. 183, p<.0001, after 4th week). 3)The functional status of the experimental group was significantly higher than that of the control group following the rhythmic walking exercise (t=13.20, p<.0001). The results suggest that the appropriate rhythmic walking exercise for the breast cancer patients in adjutant chemotherapy can improve physical strength and functional status, and ultimately decrease the secondary fatigue.

The Relationship between Bathing and Health Status / 간호학회지

PURPOSE: The purpose of this study was to test the relationship between health status and bathing. METHOD: The population of this study consisted of females, above age 20 in urban areas in order to control the effects of extraneous variables, resident areas, gender, and age. Four hundred and twenty-eight (428) women were interviewed with a structured questionnaire. Medical Outcomes Study Short Form (SF)-36 Health Survey assessed individual health status. Bathing behavior and attitudes toward bath have been measured with questionnaires designed by the authors. RESULT: The most popular bathing type was shower (46.8%). The preferred type of bath was related to health status. A common purpose of the tub-bath was relieving fatigue and hygiene, but the other purposes were different on the subjects health status. Persons with low health status took frequently tub-baths for health. Attitudes toward bath were related to health status. Women with low scores in physical health recognized more physical effects of bath than psychological effects or hygenic effects. CONCLUSION: Bathing included physical and psychological dimensions and was related to health status.

Illness Intrusiveness by Symptoms in Patients with Rheumatoid Arthritis / 성인간호학회지

PURPOSE: Illness intrusiveness (illness induced lifestyle disruption) by symptoms was investigated in 439 patients with rheumatoid arthritis. METHOD: The cross-sectional and retrospective survey design was used. Fatigue, disability, pain, and depression were considered as symptoms of rheumatoid arthritis. RESULT: Patients were reported to perceive more illness intrusiveness than other chronic disease patients such as end stage renal disease, bipolar disorder, and peritoneal dialysis patients. They were especially intrusive into work, health, and active recreation domains. Stepwise regression analysis identified four variables counting for 26% of illness intrusiveness variances: fatigue, disability, marital status, and depression. All of the symptoms except pain were found to significantly predict illness intrusiveness. Fatigue explained 16% of illness intrusiveness variances. CONCLUSION: Fatigue and depression usually overlooked by health professionals must be carefully assessed and managed to reduce perceived illness for rheumatoid arthritis patients.

Perceived Barriers to Exercise of Adults: Difference by Age, Gender and Residence / 성인간호학회지

PURPOSE: Perceived barriers to exercise were investigated for adults. METHOD: A total 1266 subjects were selected by a quota sampling method with age, gender, and residence. Perceived barriers were categorized under 4 groups: knowledge, psychological, physical, and external factors. All 23 items of perceived barriers were responded on a dichotomous (yes/no) scale. RESULT: Mean number of perceived barriers was 4.61 and 87.9% subjects perceived at least one barrier which prevented involvement in exercise. External barriers ranked highest, followed in order by psychological, knowledge, and physical barriers. Most factors of perceived barriers were found to be different by age, gender, and residence, in that, the younger, female, living in Daejeon subjects were found to respond with more barriers than the older, male, living in Chungju or Seoul. CONCLUSION: Perceived barriers to exercise are differenct by age, gender, and residence. Therefore, it is recommended that age, gender, and residence of subjects must be considered in order to develop exercise programs and public campaigns.

The Relationship of Bone Mineral Densities and Period of Breast feeding in Premenopausal Women / 간호학회지

To determine whether personal history of lactation in premenopausal women influence bone mineral density, a cross-sectional study was conducted. One hundred eighty-four premenopausal women were selected from women who had been checked for bone mineral density by dual energy x-ray absortiometry in lumbar spine, femoral neck, Ward's triangle, and trochanteric site at general hospitals in Seoul and Pusan. They completed a questionnaire including life style factors and reproductive history. In the data analysis, Pearson correlation coefficients were used to test any association between individual variables and bone mineral density and a statistical comparisons between long term lactation(>24 months) and short term lactation(24months) and the short term lactation group(24months) and the short term lactation group (<24months). Considering these results, we suggest prospective studies that measure bone mineral density before and after, in addition to those during lactation. We also suggest the further study with premenopausal women less than 35 who have achieved peak adult bone mass.

Reliability and Validity of the Measurement for Assessing Resourcefulness / 간호학회지

The purpose of this study was to verify the reliability and validity of the Rosenbaum self-control schedule(SCS) for assessing resourcefulness in Korea and to explore the simplified scale. The study subjects consisted of 787 adults in a community. The data was collected during the period from Oct. to Dec., 1995 and analyzed as Cronbach alpha item correlation with total, Perarson correlation and factor analysis with varimax rotation using SAS. Results were as follows : The mean SCS score for this sample was 17.2 and there were statistical differences for gender(men, 13.1 ; women, 20.0) on the SCS scores. The cronbach alpha of SCS with 36 items was .74 and when simplified with 30 items, it's coefficient alpha was .78. The translated content of the SCS was validated by two nursing faculty members and one professor of psychology. Factor analysis revealed the most parsimonious structure was obtained when six factors were extracted and subsequently rotated via the varimax criterion. There was 40.2% of total communality variance in the SCS with 36 items. The total communality variance was slightly increased to 43.4% with 30 items of the SCS. In order to reduce from 36 items to 30 items, the process excepted 6 items having low item correlation with total and low MSA(means of sampling adequacy) of factor analysis. According to factor analysis, there are six factors such as emotion control, impulse control, self-efficacy, coping with problems, pain control and satisfaction control. The SCS was found to have low, but statistically significant, correlations with social desirability and helplessness. From the above results, it can be concluded that the reliability of the SCS(inherent and simplified) was a acceptable level and its validity was reasonable when comparing it with other validity studies. To determine the usefulness the simplified scale, further study is necessary to simultaneously compare and analyze both scales for stability.

An Analysis of Resourcefulness Research / 성인간호학회지

The purpose of this study was to identify the trends of resourcefulness researche studies for suggesting the future direction of study. Study design, types of subjects, measurement tools, study concept, and outcome were examined by reviewing 61 research studies published from 1980 to 1999. The results were as follows: 1. There were 24 works in the 1980s and 37 works in 1990, according to the published year of resourcefulness study. Non-experimental studies like descriptive study, correlational study and comparative study were more frequent than experimental studies. 2. Research studies that consisted of 30- 100 subjects were the most numerous with 27 studies in all. The majority of study subjects was shown as healthy students and depressive patients. 3. Most studies used Rosenbaum's Self Control Schedule(SCS) for assessing resourcefulness. Reliabilities of resourcefulness researches were cronbach alpha= .70 or more. According to statisitical tests done for internal validity, SCS was negatively correlated to maladaptation. Factor analysis revealed that the most parsimonious structure was 3 to 6 factors. The total communality variance in the SCS was about 40 %. Other tools used with the SCS were about coping, depression, satisfaction of life and symptoms, self management and health romotion. 4. In correlational studies, concepts like depression, anxiety, and psychological symptoms were related to resourcefulness negatively. Adaptive functioning, life satisfaction and self achievement had positive correlations to resourcefulness. 5. Studies on comparison between a healthy person and depressive patient or smoker and non-smoker were done. There were coping, depression, symptom, self efficacy, health problem and self-control as comparative concepts. 6. Study subjects consisted of depressive patients in 9 of 18 experimental studies. The majority of studies were done with cognitive-behavioral therapy as an experimental intervention. The most effective treatment was revealed in high resourcefulness group. Since the above findings, resourcefulness research increased since 1980 and mostly non-experimental design for quantitative study were done. In the field of nursing, research about resourcefulness was in an initial stage. It is expected that further research needed to be done. Recommendations on the basis of the present research suggest that it is necessary to replicate studies, develop nursing intervention enhancing resourcefulness and apply it to patients with chronic diseases including cancer.

Stage of Change for Exercise and Health-Related Quality of Life in Korean Adults / 성인간호학회지

PURPOSE: Many studies have shown that regular exercise produces positive effects on health. The purpose of this study was to examine the differences of health-related quality of life by stage of exercise and the interaction effect of age, sex and stage of exercise. METHOD: A total of 1266 participants were interviewed with structured questionnaire. Stage of exercise was assessed with a single item and respondents were classified with respect to exercise intention and behavior. Health-related quality of life was measured with SF-36 Health Survey Questionnaire. RESULT: Health-related QOL were found to be different by stage of exercise. The subjects who were reached maintenance stage showed significantly higher scores on physical functioning, bodily pain, general health perception, mental health, role limitation due to emotional problems, social functioning, and vitality than those in preparation, contemplation, and precontemplation stage. In addition a significant interaction effect between stage of exercise and age was found on physical functioning, bodily pain, general health perception, mental health, and vitality. CONCLUSION: Perceived health-related QOL varies with stage of exercise. This finding suggests that health is related to both intention and behavior of exercise. Therefore it is important to consider cognitive-motivational and behavioral stage of change for developing exercise programs.
