The purpose of this study was to examine the relationship between self-esteem and quality of life(QOL) and between coping type and quality of life (QOL) in mothers of handicapped children and further to identify the level of self-esteem and quality of life of the subjects. The subjects of this study were the 51 mothers of handicapped children who were registered in two special schools in Taejon. The data were collected using a questionnaire and the period of the data collection was from April 18th to May 26th, 1997. The instruments for this study were Resenberg's self-esteem scale, Folkman and Lazarus's Ways of Coping Checklist(WCC) and the quality of life scale designed by Ro, You Ja. The results were analyzed using SPSS/PC+. Data analysis included the descriptive correlational statistics of ANOVA, Pearson Correlational Coefficient, and t-test. The results are as follows : 1. The level of self-esteem showed a mean score 34.51 and the level of QOL, a mean score 137.55. An Active type of coping was used more often than a passive one. 2. The level of self-esteem differed according to monthly income and was significantly higher in mothers of children with acquired handicaps than those of children with congenital handicaps. The level of QOL differed according to monthly income. 3. There was positive correlation between health status and self-esteem(r=.355, p<.05), and between health status and QOL(r=.367, p<.01). 4. Test for hypothesis ; Hypothesis 1, "The higher the level of self-esteem in mothers of handicapped children, the higher their level of quality of life will be." was supported(r=.755, p<.001). Hypothesis 2, "The QOL level for the active coping group as compared to the passive coping group will be higher." was not supported.
The purpose of this study was to determine the effect of periodic walking during hindlimb suspension on the mass, relative weight, fiber type distribution and cross-sectional area of Type I and II fibers in the developing Type II plantaris muscle. To examine the effectiveness of periodic walking on mass and fiber size, the hindlimbs of young female Wistar rats were suspended(HS group) and half of these rats walked on a treadmill for 45 min/day(15 min every 4 hours) at 5 meters/min at a 15 degree grade(HS-W group) After seven days of hindlimb suspension, the plantaris muscle wet weight was 28.40% significantly smaller (P<0.005) and relative plantaris muscle weight was 26.97% smaller compared with those of control rats(P<0.05). The plantaris muscle wet weight and the relative plantaris muscle weight increased by 46.60% and 49.23% respectively with periodic walking, moreover, the plantaris muscle wet weight and the relative plantaris muscle weight of the HS-W rats recovered to the level of the control rats. No change was observed in fiber type percentage of the developing plantaris muscle following one week of hindlimb suspension or periodic walking during hindlimb suspension. Type I and II fiber cross-sectional areas of the developing plantaris muscle were 42.51% and 43. 68% lower in the HS group than in the control group(p<0.0001), Type I and II fiber cross-sectional areas of the developing plantaris were 30.82% and 45.97% greater in the HS ?W group than in the HS group(p<0.0001), whereas Type I and II fiber cross-sectional area of HS-W group were less than those of the control group(P<0.0001) The results suggest that periodic walking can attenuate developing plantaris muscle atrophy induced by hindlimb suspension.
PURPOSE: This study was to determine the effect of DHEA administration before, during, and after dexamethasone treatment on body weight and TypeI,II muscle weight of rat receiving dexamethasone treatment. METHOD: Wistar rats were divided into 6 groups: control(C), dexamethasone(D), DHEA administration for 3days after dexamethasone treatment for 7days(7D+3DH), dexamethasone treatment for 7days after DHEA administration for 3days(3DH+7D), DHEA administration during dexamethasone treatment for 4days after dexamethasone treatment for 3days(3D+4DDH), DHEA administration during dexamethasone treatment for 7days(7DDH). Dexamethasone was injected by subcutaneously daily at a dose of 5mg/kg. DHEA was orally administered daily at a dose of 5mg/kg for 7 days. Soleus(TypeI) muscle, and both plantaris and gastro- cnemius(TypeII) muscles were dissected on the 7th day of experiment. RESULT: Body weight of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. Body weight of 7D+3DH group decreased significantly compared with that of 7D group, 7DDH group, 3DH+7D group and 3D+4DDH group. Muscle weight of both plantaris and gastro- cnemius tended to decrease compared with that of 7D group. Muscle weight of 7DDH group, 3D+4DDH group and 3DH+7D group increased significantly compared with that of 7D+3DH group. Muscle weight of gastrocnemius of both 3DH+7D group and 3D+4DDH group increased significantly compared with that of 7D group. CONCLUSION: Based on these results, it can be suggested that DHEA administration before and during dexamethasone treatment can increase both body weight and mass of atrophied TypeII muscle induced by dexa- methasone treatment.

PURPOSE: The primary purpose of this study is to provide a useful insight for developing effective teaching and student counseling methods by understanding the relationship between four preference patterns of MBTI personality types and EWHA defense mechanisms of nursing college students.
METHOD
The data used in this research were collected administrating EWHA defense mechanism test and MBTI personality type instrument to 195 nursing students in the period of November 3 through September 16 in 2000. Collected data were analysed by pc-SPSS 10.0.
RESULT: Three general conclusions were drawn from the study results: (1) in terms of personality type, 'Extraversion', 'Sensing', 'Thinking', and 'Judgement' types showed high frequency respectively; (2) in terms of defense mechanism, 'Identification' showed the highest score, and then 'suppression' scored next followed by 'Humor'. However, 'Acting out' showed the lowest average score, and then 'Projection' followed by 'Denial'; (3) Based on the relationship between defense mechanism and four MBTI preference patterns, it can be drawn that students with the preference of 'Extraversion' usually use defense mechanism of 'Altruism', 'Sublimation', 'Distortion', 'Controlling', and 'Humor'. In comparison, students with the preference of 'Introversion' often use the defence mechanism of 'Evasion' and 'Projection'.
CONCLUSION: The study results can be utilized in both fields of education and counseling: (1) in the field of education, this study can provide a basis for developing a suitable teaching method for each personality types of nursing students; (2) for counseling practitioners, the results of this study provide the useful insights to understand nursing college students' communication skills, behavior patterns, and ability of coping with problems in the process of counseling.

PURPOSE: This study was to identify the relationship between personality type, college admission SAT scores and GPA scores of student nurses.
METHOD
The data was collected from 270 student nurses enrolled in a baccaleaureate program in Seoul. MBTI was used to identify students' personality and SAT score and GPA score were collected over 4 years. The collected data was analyzed by using SPSS Win. package.
RESULT
1. There were slightly more extrovert (E) type (54.4%) students than the introvert (I) type; more sensing (S) type (71.1%) than the intuitive (N) type. 2. The introvert type students had significantly higher SAT scores than those of the extrovert type (p=.002). 3. The judging type students had significantly higher GPA scores throughout their college years than the perceiving type. 4. There was no statistically significant relationship between SAT and GPA scores. SAT scores did not accurately predict students' academic achievement in college in this sample.
CONCLUSION
The distribution of the personality types in the sample was different from the general population which may suggest that college admission criteria is biased toward certain personality type. Since different personality types process information and cope with the outside world differently, effective teaching strategies need to be considered for each class.

PURPOSE: The aim of this study was to identify the present situation of hospital infection and route of infection by clarifying the transmission aspect of methicillin-resistant Staphylococcus aureus(MRSA) in a Neurosurgical Intensive Care Unit by analysing genotype. METHODS: MRSA was cultured from twenty five patients with a tracheostomy, twenty five health care workers, and environments in the Neurosurgical Intensive Care Unit of one hospital in D city. Data was collected from December 21, 2004 to November 5, 2005. MRSA isolates representing each genotype were analyzed by spaA typing and a multiplex PCR method capable of identifying the structural type of the staphylococcal cassette chromosome mec(SCCmec) carried by the bacteria. RESULTS: As the same genotype and gene sequence were found among health care workers, patients, and environments, it was assumed that there was cross transmission among them. CONCLUSION: This study suggests that first, as the hospital infection by MRSA between health care workers and patients in the Neurosurgical Intensive Care Unit was due to result of cross transmission and the relevance of transmission between them was verified, it is necessary to take preventive measures and conduct education. Secondly, development of nursing interventions and study of infection are needed. Thirdly, consistent investment in prevention against hospital infections and environmental renovation is needed.

The current study was aimed to investigate the transformational experience of a female student nurse living with type 1 diabetes.
A case study of a 24-year-old diabetes patient was conducted, with interviews concerning the evolving process she had lived through during the period from her later high school years to her graduation from nursing college.
Followings were identified as 5-transformation process: With her diabetes-related limitation, the participant experienced ‘ conflict involving choosing a college and major’. The participant tried to be in charge of managing her diabetes and stepped forward to ‘ adaptation to college life as a new environment’, and she learned more about the process of ‘ evolving awareness of caring’ and developed herself further through the process of ‘ integration of the nurse identity into self-identity’, and finally through the process of ‘ progression and preparation for getting a job’ she achieved her goals, being positive about the future.
The results of the study can provide individuals with diabetes a way of self-management and help the patients and their families in diabetes education. Further research will be needed to refine the results of this study and to learn more about the experiences of patients with type I diabetes in college years.
The purpose of this study was to compare the feeling state guided imagery(FSGI) and end state guided imagery(ESGI) on stress and performance of an intramuscular injection of nursing students.
The design was a time series with a nonequivalent control group pretest-posttest study. Data was collected from the 23 rd to the 25th of Nov. 2004. The subjects of this study were 40 female sophomores (21 for the ESGI, 19 for the FSGI). The instruments used in this study were the Visual Analogue Scale for Stress and the Nursing Skill Performance Check-list on Intramuscular Injection developed by the researchers(10 items). Guided imagery was provided through audiotapes for 8 minutes. A pretest was given before applying the guided imagery, posttest 1 was performed after the intervention, posttest 2 was performed before the intramuscular injection and then evaluation of the performance of the intramuscular injection was done. Data was analyzed using t-test, and Repeated Measures ANOVA.
The level of stress for those who received the ESGI and FEGI was not significant and the level of the nursing skill performance for those who received the ESGI was significantly higher than that of students who received the FEGI.
The use of ESGI has an effect on learning psychomotor nursing skills and further research is needed on stress.

The purpose of the study was to identify the effects of problem solving nursing counseling and intensified walking exercise on diabetic self-care, coping strategies, and glycemic control among older adults with DM type II.
Ninety nine DM patients who were older than 50 were recruited from DM clinics or public health centers and conveniently assigned into three groups: the Polar(n=41), counseling(n=30) and control groups (n=28). Participants in both Polar and counseling groups attended weekly problem solving nursing counseling for 12 weeks. Polar heart rate monitors were used in the Polar group to intensify walking exercise. Data was collected from November 2003 to August 2004 and analyzed by ANOVA or ANCOVA using the SPSS WIN program.
After a 12 week intervention, participants in both the Polar and counseling groups reported increased diabetic self care behaviors and decreased blood glucose levels, which is significantly different from those in the control group. There were no distinctively different program effects between the Polar and counseling groups.
Based on the findings, we concluded that problem solving counseling alone could have positive effects on diabetic self care and glycemic controls for older adults with DM. Future research is needed to identify long-term effects of the program.

The purpose of this study was to evaluate the effect of web-based diabetic education on plasma glucose and serum lipids in obese people with diabetes.
A random allocation design with control and experimental groups being assessed pre- and post-intervention was used. Eighteen patients were randomly allocated to an intervention group and 16 to a control group. Participants were requested to input their blood glucose levels weekly for 3 months at http://www.biodang.com by cellular phone or wire Internet. The researcher sentoptimal recommendations to each patient weekly for 3 months using a short message service (SMS) of the cellular phone and wire Internet.
Patients in the intervention group had a mean decrease of 1.2% in glycosylated haemoglobin (HbA1c) levels and those in the control group had no difference in HbA1c levels. There was a significant mean change in 2-hour post prandial blood glucose (2HPPG) for the intervention group, with a mean change of -120.1 mg/dl. The mean change in the control group, however, was not significant.
These findings indicate that this web-based intervention using SMS of the cellular phone for 3 months improved HbA1c and 2HPPG, but did not affect total cholesterol, triglyceride, and high density lipoprotein cholesterol in obese type 2 diabetic patient.

The purpose of this study was to examine the effects of problem solving nursing counseling and walking exerciseon weight loss, cardiovascular risk factors, and self-efficacy of diabetic control among obese diabetic patients. The Polar heart rate monitor was used for walking exercise to utilize the Biofeedback mechanism.
Fifty nine diabetic patients were conveniently placed into experimental (n=35) and control groups (n=24). The experimental group participated inweekly nursing counseling for 12 weeks and was encouraged to do walking exercise using a Polar monitor. The control group remained in the same treatment as before. The data wascollected from November 2003 to August 2004 and analyzed using t-tests and ANCOVAs.
After 12 weeks, the participants in the experimental group reported significantly decreased body weight (p=.004) and total scores on theParma scale (p=.001). While the participants in the control group reported significantly increased levels of blood triglyceride (p=.046) and HDL (p=.018).
Based on the findings, we concluded that problem focused nursing counseling with intensified walking exercise could reduce the risk of cardiovascular complications and body weight among obese diabetic patients. Future research to explore the long-term effects of nursing counseling on diabetic complications is warranted.

The purpose of this study was to explore the levels of depression experienced by clients (N=152) with Type 2 Diabetes Mellitus(DM), and to compare the levels of self care activity, metabolic control and cardiovascular risk factors between depressed and non-depressed clients.
Participants aged 50 and above were conveniently recruited in B city. The levels of depression, self-care activity, metabolic control of glucose and lipids, and cardiovascular risk factors of the participants were measured by using questionnaires and blood tests from November, 2003 to June, 2004. Data was analyzed with descriptive statistics, Pearson correlation, Spearman rho and t-test using the SPSS WIN 10.0 program.
The prevalence of depression(CES-D=16) among the participants was 44.1%. The levels of self-care activities(p=.012), glucose(p=.019), total cholesterol(p=.022), LDL(.007) and cardiovascular risk factors(p=.012) were significantly higher in the depressed group than those in the non-depressed group.
Based on the findings, we concluded that many DM patients experience depression and the depression of type 2 DM clients is significantly related with self care activities, diabetic control, and cardiovascular complications. However, this study did not address causality among these variables. Therefore, further research, such as a longitudinal cohort study, is needed to identify causality among these variables.

This study was to evaluate the effects of a short term comprehensive life style modification program on glycemic metabolism, lipid metabolism and body composition in type 2 diabetes mellitus patients.
A nonequivalent control group with a pre post test was designed. Data collection was done from October 2003 to June, 2004 at a hospital. Glycemic metabolism was measured by a.c., p.c. and HbA1c, and lipid metabolism was measured by cholesterol, HDL cholesterol, LDL cholesterol and triglycerides. Body Composition was measured by body weight, body mass index, waist, measurement waist per hip ratio, body fat, muscle weight and abdominal fat tissue(intra abdominal distance). The Experimental group, which was composed of 29 participants, was educated based on a life style modification protocol at a weekly meeting for 12 weeks and carried out exercise, diet along individual parameters and self monitoring, while 24 participants in the control group received only diet education.
1.The experimental group showed a significant lower a.c.(t=2.11, p=.04) and HbA1c(t=2.65, p=.01) compared to those of the control group. 2. The experimental group showed a significant lower LDL than the results of the control group(t=2.42, p=.02). 3. The experimental group showed a significant lower weight(t=3.09, p=.00), BMI(t=3.01, p=.00), body fat(t=2.94, p=.01) and abdominal fat tissue(t=3.05, p=.01) than those of the control group.
The results provided evidence for the effectiveness of a short term comprehensive life style modification program composed of exercise, diet, support, self efficacy elevation and self monitoring in type 2 diabetes mellitus.

This study was to determine the effect of oral vitamin C supplements on blood sugar and antioxidative status in Types II diabetes mellitus patients.
Data for the study were collected from June 24 to August 31, 2001. Participants(31) took 1g/day vitamin C for 4 weeks, after a 1 - week taking no Vitamin C, followed by Vitamin C 3g/day for 4 weeks. A baseline blood sample was obtained following a 12hour overnight fast and at the end of each 4week Vitamin C administration. Blood samples were taken for plasma vitamin C concentration, fasting blood sugar, HbA1c, superoxide scavenging activity and hydrogen peroxide scavenging activity. The data were analyzed by SPSS for repeated measures ANOVA.
Plasma vitamin C concentration was significantly increased over dose(F=3.316, p=.043). Fasting blood sugar and HbA1c was significantly decreased over dose(F=13.192, p=.000; F=11.995, p=.000). Superoxide scavenging activity and hydrogen peroxide scavenging activity was significantly increased over dose(F=486.138, p=.000; F=177.704, p= .000).
The results suggest that megadose vitamin C supplementation may have a beneficial effect in diabetes mellitus patients on both glycemic control and antioxidant status. Thus dietary measures to increase plasma vitamin C may be an important health strategy for reducing the compliance of diabetic patients.

The purpose of this study was to construct and test a structural equation model for Diabetes self-management (DSM) behavior and Quality of life (QoL) in older adults with diabetes who use Citizen Health Promotion Centers. The theory used this study was a combination of the Information-Motivation-Behavioral Model (IMB) and Self-Determination Theory (SDT) to reflect autonomous characteristics of participants.
Data were collected from April 20 to August 31, 2015 using a self-report questionnaire. The sample was 205 patients with type 2 Diabetes who regularly visited a Citizen Health Promotion Center. SPSS 22.0 and AMOS 22.0 programs were used to analyze the efficiency of the hypothesized model and calculate the direct and indirect effects of factor affecting the participants’ DSM behavior and QoL.
The supported hypotheses were as follows; 1) The variable that had a direct effect on QoL was health behavior adherence (γ=.55,
The major findings of this study are that supporting patient's autonomous motivation is an influential predictor for adherence to DSM behavior, and integrative intervention strategies which include knowledge, experience and psychosocial support are essential for older adults with diabetes to continue DSM behavior and improve QoL.

The purpose of the study was to identify factors influencing physical activity among community-dwelling older adults with type 2 diabetes. The study design was based on the Theory of Triadic Influence.
A total of 242 older adults with type 2 diabetes participated in this study. Six variables related to physical activity in older adults, including self-efficacy, social normative belief, attitudes, intention, experience, and level of physical activity, were measured using reliable instruments. Data were analyzed using descriptive statistics, Pearson's correlation analyses, and a path analysis.
The mean physical activity score was 104.2, range from zero to 381.21. The path analysis showed that self-efficacy had the greatest total effect on physical activity. Also, experience had direct and total effects on physical activity as well as mediated the paths of social normative beliefs to attitudes and intention to physical activity. These factors accounted for 10% of the total variance, and the fit indices of the model satisfied the criteria of fitness.
The findings of the study reveal the important role of self-efficacy and past experience in physical activity in older adults with type 2 diabetes.

The objective of this study was to provide a trend analysis of the prevalence of diabetes relative to the socioeconomic, lifestyle, and physiologic risk factors among Korean adults aged over 30 years for a 10-year period using data from the Korean National Health and Nutrition Examination Survey.
Prevalence difference and the slope index of inequality were calculated for each risk factors using binomial regression by considering the repeated cross-sectional features of the data. The prevalence ratio and the relative index of inequality were calculated using log-binomial regression. Linear trend tests were performed using SAS 9.2.
Crude prevalence of diabetes increased over the 10-year period, and was higher for men than for women. It was very high for adults 60 years or over, consistently increasing over time. The prevalence among unemployed men, women with higher level of stress, women with hypertension, and adults with serum triglyceride levels over 135 mg/dL increased over the 10-year period in comparison with the respective control group.
Considering the rapid economic development and associated lifestyle changes in Korea, action should be taken to control the prevalence of diabetes by both preventing and consistently monitoring these identified risk factors using a public-health approach.

The study was conducted to develop and test a hypothetical model which explains self-care behavior in patients with type 2 diabetes was established based on the Self-Determination Theory.
The participants were 218 patients with type 2 diabetes mellitus enrolled in an outpatient clinic of one endocrine center in Korea. The data were collected using questionnaires from April 5 through May 7, 2010. The descriptive and correlation statistics were analyzed using the SPSS/WIN 15.0 and the structural equation modeling procedure was performed using the AMOS 7.0 program.
The results of this study showed that competence and autonomous motivation were the strong factors influencing self-care behavior in patients in this sample. Support from health provider for autonomy was a significant indirect factor on self-care behavior. These factors explained 64.9% of variance in the participants' self care behavior. The proposed model was concise and extensive in predicting self-care behavior of the participants.
Findings may provide useful assistance in developing effective nursing interventions for maintaining and promoting self-care behavior in patients with type 2 diabetes.

The purpose of the study was to investigate the relationships between the Myers-Briggs Type Indicator (MBTI) psychological type and marital satisfaction, divorce proneness, positive affect, and conflict regulation in couple visiting a clinic.
Couples (n=62) who visited "M" couple clinic participated in the study. Data were collected from March to June 2009 using the Marital Satisfaction Scale, Marital Status Inventory, Positive Affect Inventory, and Conflict Regulation Inventory.
The couples showed no significant differences in marital satisfaction, positive affect, and conflict regulation according to similarities between spouses in MBTI types. However, they showed significant differences in divorce proneness of husband according to a similarity in the Sensing/Intuition indicator. They also showed significant differences in divorce proneness, positive affect, and conflict regulation between the couples for ISTJ (Introversion, Sensing, Thinking, Judging) or ESTJ (Extraversion, Sensing, Thinking, Judging) types compared to other couples.
When nurses counsel couples, they should understand that differences in psychological type between spouses affects their marital relationship. In addition, nurses should educate couples on the characteristics of each type according to the couple's types and help them to understand each other, especially for couples where one spouse is the ISTJ/ESTJ type. These interventions will improve marital satisfaction and prevent the divorce in these couples.

The purpose of this study was to examine the effects of daily exercise before steroid treatment on mass, the type I and II fiber cross-sectional area, and myofibrillar protein content of hindlimb muscles in a rat model.
Adult male Sprague-Dawley rats were randomly assigned to one of three groups: a control group(n=10) that had a normal saline injection for 7days, a steroid group(n=10) that had a steroid injection for 7days, and an exercise-steroid group(n=10) that ran on the treadmill for 7days before a steroid treatment. Body weight and food intake were measured every day. At 15 days all rats were anesthetized and the soleus, plantaris and gastrocnemius muscles were dissected.
The exercise-steroid group showed significant increases as compared with the steroid group in body weight, muscle weight of the soleus and gastrocnemius, type II muscle fiber cross-sectional area of plantaris, and myofibrillar protein content of the soleus, plantaris, and gastrocnemius. As compared with the control group, the steroid group showed significant decreases in body weight and diet intake, muscle weight, the type II fiber cross-sectional area and myofibrillar protein content of the soleus, plantaris, and gastrocnemius muscles.
Daily exercise before steroid treatment attenuates hindlimb muscle atrophy, with type II muscle changes more apparent than type I muscle changes.

The purpose of this study was to examine the effects of cerebral ischemia on Type I(soleus) and Type II(plantaris, gastrocnemius) muscles, and to determine the effects of isometric contraction training by electrostimulation on Type I andII muscles in cerebral ischemia model rats.
Twenty-five male Sprague-Dawley rats were randomly divided into four groups: ST(stroke), STES(stroke+electrostimulation), SH(sham) and SHES (sham+electrostimulation). The ST and STES groups received a transient right middle cerebral artery occlusion operation. The SH and SHES groups received a sham operation. The STES and SHES groups had daily isometric contraction training by electrostimulation(100Hz, 45mA, 7.5V) on hindlimb muscles for 7days.
Plantaris and gastrocenmius muscle weight, myofibrillar protein contents of soleus and gastrocnemius, and the muscle fiber cross-sectional area of gastrocnemius in the ST group significantly decreased compared with the SH group. Soleus, plantaris, gastrocnemius muscle weight, myofibrillar protein contents of soleus and gastrocnemius, and the Type I muscle fiber cross-sectional area of soleus and the Type II muscle fiber cross-sectional area of gastrocnemius in the STES group significantly increased compared with the ST group.
Hindlimb muscle atrophy occurs after acute stroke and isometric contraction training by electrostimulation during early stages of a stroke attenuates muscle atrophy of Type I and Type II muscles.

This study was to evaluate the effects of a comprehensive life style modification program on glycemic control and stress response in type 2 diabetes.
The participants(n=34) with type 2 diabetes were divided into either a usual care(control) or treatment(experimental) group. The experimental group(n=21) received a program that was based on a comprehensive life style modification protocol at a weekly meeting for 16 weeks. They also participated in individually prescribed exercise and diet along with stress management and self monitoring. The participants were followed for 6 months, during which postprandial glucose, HbA1C, and stress response inventory were measured.
The experimental group showed a significant lower postprandial glucose and stress response compared to those of the control group. However, there was no significant change in the HbA1C value in either group.
These results suggest that a type 2 diabetes comprehensive lifestyle modification program may lead to clinical improvement in glycemic control and reduce the stress response.

The goal of this study was to investigate the factors influencing health promoting behaviors in elderly individuals according to types of residency.
This was a descriptive study. The subjects were comprised of 243 elderly aged 65 years or over living in 3 large cities. The instruments used for this study were a health promoting lifestyle, perceived health status, geriatric depression short form scale-Korea, social support scale, and self-efficacy. The data was analyzed using SPSS Win 12.0.
Powerful predictors of a health promoting lifestyle were depression, self-efficacy, and perceived health status for the elderly living at home. In the cases of the elderly living in institutions, a powerful predictor of a health promoting lifestyle was identified as social support.
For the operation of long-term care insurance, a service for home care programs is needed for the elderly living at home in order to reduce depression and to increase self-efficacy and perceived health status. In addition, social support provided by health-care professionals should be developed to promote a healthy lifestyle for the elderly living in institutional environments.
