Abstract Aims: The goal of Coronary Artery Bypass Graft surgery (CABGs) is to improve the quality of life in patients with coronary artery diseases. Many studies have suggested the implementation of a cardiac rehabilitation program after surgery required to achieve this goal. The aim of this study was to examine the effects of cardiac rehabilitation on quality of life in post-surgery patients. Materials & Methods: In this quasi-experimental which was conducted in 2012, 70 patients (35 patients in experimental group and 35 patients in control group) undergoing CABGs in Shahid Rajaei Heart Center of Tehran City were selected by achievable sampling method. The experimental group received 12 sessions of cardiac rehabilitation program according to their health condition. The control group was not participating in the rehabilitation program. The qualities of life of patients of both groups were measured by Ferrans & Powers Questionnaire of quality of life before and after the cardiac rehabilitation program. Data were analyzed in SPSS 16 software by Paired T, independent T and linear regression tests. Findings: The experimental and the control group were matched according to age and sex. There was no significant difference between two groups before intervention in the quality of life score. After intervention, the quality of life score were increased in both the experimental (19.99±1.11) and the control groups (18.49±1.48), respectively (p<0.001). Conclusion: Participation in cardiac rehabilitation program is effective in promotion of quality of life in CABG patients.

Aims: Type 2 diabetes is a metabolic disorder that affects the quality of life and mental health of the patients. There are different recommendations about doing effective exercise for diabetic patients. The aim of this study was to evaluate the effect of two aerobic trainings and a detraining periods on quality of life and mental health in women with type 2 diabetes.

Materials & Methods: In this Semi-experimental research in 2011 in Sabzevar City, Iran, 33 women with type 2 diabetes in 40-60 years age range were selected purposefully and were divided into 3 groups each contain 11 samples; control, daily 5-week aerobic exercise and every other day 10-week aerobic exercise. Aerobic training was conduct with an intensity of 60-70% of maximum heart rate for 30-60min per session. The research instruments were the Quality of Life and Mental Health questionnaires. Data analyses were done in SPSS 18 software by repeated measures ANOVA, one-way ANOVA and Tukey post hoc tests.

Findings: There were significant differences between quality of life (p=0.002) and mental health (p=0.04) of training groups and control group, but two training groups were not significantly different. There were also significant differences in physical (p=0.004) and psychosocial (p=0.004) domains of quality of life between the three groups at 5- and 10-weeks after the start of the exercises.

Conclusion: Daily 5-week and every other day 10-week aerobic exercises improves mental health and quality of life in women with type 2 diabetes, but the benefits are not maintained after 2 months of detraining.

Aims: As other life periods, aging is characterized by physical, mental, and social changes. In the adaptation with such changes, the elderly might face with problems such as sense of helplessness and emotional disturbances, while their quality of life is affected. The aim of this study was to determine the roles of anxiety and depression, as well as the demographic factors, in the prediction of the quality of life of the retired elderly in Gonabad Township.

Instrument & Methods: In the descriptive correlational study, the elderly, who were members of Gonabad Township Retired Center, were studied. 200 persons were randomly selected. Data was collected by four questionnaires including a demographic, Beck depression, Beck anxiety, and quality of life. Data was analyzed by SPSS 19 software using stepwise multiple regression analysis and the effect coding tests.

Findings: Mean anxiety level of the samples was 12.47±7.49. Mean depression level was 15.58±11.07. The quality of life (78.11±14.58) included mental health (29.60±6.24), social relationships and life environment (24.25±5.66), and physical health (24.26±4.71). There was a significant correlation between total mean of quality of life and depression and anxiety, but without any significant correlation with the demographic characteristics. Depression and the sum of depression and anxiety predicted 35.8% and 40.1% of the variance of quality of life, respectively. There was a lineal correlation between depression and anxiety and the quality of life. 17.9%, 30.2%, 21.3%, 39.9%, and 16.1% of the variance of quality of life were predicted by age, diploma certification, post-diploma certification, income, and marital status, respectively.

Conclusion: Anxiety, depression, and some demographic characteristics are the predictors of the quality of life of the elderly.

Aims: Self-controling and non-drug intervention methods such as aerobic activities and diet programs have a significant impact on insulin resistance and quality of life in type II diabetic patients. The purpose of this research was to investigate the effect of 12 weeks of aerobic training with diet on insulin resistance and quality of life in type II diabetic patients.

Materials & Methods: In this quasi-experimental research in 2013-14, obese female with type II diabetes in Taybad City, Iran, were selected by achievable sampling method and were divided into aerobic training (n=12) and aerobic training with diet (n=11) groups. Aerobic training in both groups was performed in 36 sessions of exercise training 3 sessions per week with an intensity of 50-70% heart rate reserve. In addition to aerobic training, the second group participated in diet that included 500kcal of energy less than the estimated daily energy requirement. Data were analyzed with SPSS 16 software by paired and independent T tests.

Findings: The levels of blood glucose, insulin and insulin resistance reduced significantly just in aerobic training with diet group (p<0.05) just the fasting blood sugar difference was significant between 2 groups (p=0.035). Also, there were significant differences between groups in subscales of role limitations due to physical health problems (p=0.001), role limitations due to emotional problems (p=0.002), social functioning (p=0.002), pain (p=0.001) and general health (p=0.002).

Conclusion: 12 weeks of aerobic training with diet lead to improvement in blood sugar, fasting insulin, insulin resistance and some subscales of quality of life in type II diabetic patients.

Aims: Diabetes is the most prevalent metabolic disease in human being. Self-care is the most important way of preventing complications. This study aimed at investigating the effects of peer-education on quality of life in adult patients with type 2 diabetes.
Materials & Methods: This semi experimental study was conducted at a diabetes clinic affiliated to Gonabad University of medical sciences, Iran in 2017 among 80 patients with type 2 diabetes. Patients were selected based on available sampling method, and they were randomly divided into two groups, namely intervention and control (40 patients each group). The data of all patients were collected by demographic and disease information questionnaire and diabetic patient quality of life (QOL) questionnaire. The present study was carried out in three main steps: In the first step (before intervention), peers were trained by the researcher during four sessions. In the second step (intervention), quality of life of patients was assessed before training; then, patients in intervention group were trained and instructed during three sessions; the control group received the usual instruction, too. In the third step (one month later), quality of life of patients in both groups was assessed. The data were analyzed by SPSS statistics software Version 20, using Chi-square, Fisher, independent t test, paired t test, Mann-Whitney U, and Wilcoxon.
Findings: The mean scores of quality of life in intervention group did not have any significant difference with control group before instruction (p>0.05). After instruction, the mean scores of quality of life in the intervention group compared with the control group increased significantly (p<0.001).
Conclusion: Peer education improves quality of life in adult patients with type 2 diabetes.

Aims In chronic and incurable illnesses, the quality of life and its related factors are of significant importance. We aimed to investigate the predictors of Health-Related Quality of Life (HRQoL) in Human Immunodeficiency Virus (HIV)-positive individuals.
Methods & Materials Our sample included 90 HIV-infected individuals who were under Antiretroviral Therapy (ART) in Imam Khomeini Hospital of Tehran, Iran, in 2016-2017. The HRQoL questionnaire, Prospective-Retrospective Memory Questionnaire (PRMQ), Instrumental Activities of Daily Living (IADL) interview, and flowcytometry test to assess CD4 count were used for data gathering. The obtained data were analyzed using descriptive statistics, including frequency and standard deviation and inferential statistics, including correlation and stepwise regression analyses. SPSS was used for data analysis, as well.
Findings The present study data revealed that prospective/retrospective memory complaint and daily living functioning were predictors HRQoL in individuals with HIV (P<0.001, F2,85=22.70, R2 adj=0.55). The collected data also suggested that CD4 count, viral load, gender, age, and education did not predict HRQoL in the explored HIV-positive individuals (P>0.05). 
Conclusion Prospective and retrospective memory and daily living functioning were the major predictors of HRQoL among the investigated HIV-infected individuals.
