Abstract
Phenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians' migration decisions are still unclear. Despite its wide coverage in the media and among physicians in Türkiye, and being the subject of much debate, there is insufficient data to justify this attention. With this study, we aimed to investigate the tendency of senior medical students in Türkiye to pursue their professional careers abroad and its related factors. Approach: This cross-sectional study involved 9881 senior medical students from 39 different medical schools in Türkiye in 2022. Besides participants' migration decision, we evaluated the push and pull factors related to working, social environment and lifestyle in Türkiye and abroad, medical school education inadequacy, and personal insufficiencies, as well as the socioeconomic variables that may affect the decision to migrate abroad. The analyses were carried out with a participation rate of at least 50%. Findings: Of the medical students, 70.7% had emigration intentions. Approximately 60% of those want to stay abroad permanently, and 61.5% of them took initiatives such as learning a foreign language abroad (54.5%) and taking relevant exams (18.9%). Those who wanted to work in the field of Research & Development were 1.37 (95% CI: 1.22-1.54) times more likely to emigrate. The push factor that was related to emigration intention was the "working conditions in the country" (OR: 1.89, 95% CI: 1.56-2.28) whereas the "social environment/lifestyle abroad" was the mere pull factor for the tendency of emigration (OR: 1.73, 95% CI: 1.45-2.06). In addition, the quality problem in medical schools also had a significant impact on students' decisions (OR: 2.20, 95% CI: 1.83-2.65). Insights: Although the percentage of those who want to emigrate "definitely" was at the same level as in the other developing countries, the tendency to migrate "permanently" was higher in Türkiye. Improving working conditions in the country and increasing the quality of medical faculties seem vital in preventing the migration of physicians.

Abstract
This study was aimed to determine the efficacy of homologous (only CoronaVac or only Pfizer-BioNTech) and heterologous (CoronaVac and Pfizer-BioNTech) vaccines during the period when the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron variant was dominant in Türkiye. Coronavirus disease-2019 (COVID-2019) infection was confirmed by reverse transcriptase polymerase chain reaction and data on vaccination status against COVID-19 were evaluated during the period of 15 January 2022-1 May 2022 when the SARS-CoV-2 Omicron variant was dominant among 1854 employees followed in the SARS-CoV-2 Vaccine Cohort of Manisa Celal Bayar University (MCBU) Hospital Health Workers. Two separate reference groups were used in the evaluation of vaccine efficacy: those who were never vaccinated and those who received only two doses of CoronaVac. The efficacy of homologous and heterologous vaccine models was evaluated with relative risks and attributable risk percentages. MS Excel, SPSS 23.0 and STATA 14.1 package programs were used for statistical analysis. The mean age of the participants was 36.6 ± 10.0. During the period from January 15th to May 1st 2022, 372 hospital workers were infected with COVID-19. Taking the never vaccinated as the reference group, the most effective model was found to be only the three or more doses of the Pfizer-BioNTech primary vaccination model (85.8%, 95% CI= 40.7-96.6). Models consisting of a single dose of CoronaVac (6.5%, 95% CI= -56.3-44.2) or a single dose of Pfizer-BioNTech (17.7%, 95% CI= -30.2-48.0) booster dose administered after two doses of primary CoronaVac vaccination was not found to be effective against the SARS-CoV-2 Omicron variant. When only two doses of primary CoronaVac vaccination model was taken as the reference group, the model consisting of two doses CoronaVac followed by two Pfizer-BioNTech booster doses was effective as 38.4% (95% CI= 15.4-55.3), whereas three doses of Pfizer-BioNTech booster model was effective as 56.4% (95% CI= 33.9-71.3). To conclude, none of the models other than the homologous or heterologous vaccine models containing at least three doses of Pfizer-BioNTech vaccine were effective compared to those unvaccinated. Compared with those who received only two doses of primary Coronavac, models with at least three doses of Pfizer-BioNTech reminder doses were more effective against the Omicron variant than other models.

Abstract
In this study, it was aimed to evaluate one-year follow-up of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) specific antibodies formed against the virus binding site, in a coronavirus disease-2019 (COVID-19) positive case cohort (n= 413) between the period March 2020 to December 2020 in Manisa Celal Bayar University Hospital, until July 2021. SARS-CoV-2 antibodies were determined by the chemiluminescent enzyme immunoassay (CLIA) method. Values of 1.0 and above were considered positive. Chi-square tests and Joinpoint regression analysis (version 4.7.0) were used in the statistical analyses. The mean age of the participants was 34.9 ± 9.3 and 60.2% of them were women. Between 21-30 days after the diagnosis of COVID-19, total antibody level was above the threshold value in 72.2% (n= 126) of the participants, while this rate increased to 79.1% (n= 240) in 31-60 day interval. In the following period, this rate decreased to 38.8% (n= 108) in days 211st to 240th. Antibody response could not be detected in 76 (20.7%) of 367 employees who have initially been followed up. The percentage of total antibody positivity prevalence ranged from 98.9% to 96.1% in the 31-210th day after diagnosis, in the follow-up of 291 employees whose total antibody positivity was detected after diagnosis. According to the results of the Joinpoint regression analysis, after the diagnosis of COVID-19, the curve showing the percentage of antibody positivity was broken at two points: The first breaking point was observed in 181-210th days (6-7 months) (p= 0.069), and the second breaking point was in 271-300th days (9-10 months) (p< 0.001). As a result, the highest antibody positivity rates were detected after the 30th day of the disease onset and antibody positivity was maintained in the first seven months after diagnosis; the antibody positivity rate decreased to 25% at the end of the first year.

Abstract
The COVID-19 pandemic became a challenge to maintain care for patients with idiopathic intracranial hypertension (IIH). We aimed to find out how they were affected during lockdown. Thirty IIH patients admitted to hospital during the COVID-19 pandemic were studied. Their demographic and neuro-ophthalmological findings were evaluated. The World Health Organization - Five Well-Being Index (WHO-5), the EUROHIS Quality of Life (QOL) 8-item index, National Eye Institute Visual Functioning Questionnaire (NEI-VFQ-25), Headache Impact Test (HIT-6), and COVID-19 Fear Scale were used to assess QOL and pandemic-associated fear. Thirty age, sex, and body mass index matched volunteers constituted the control group. Apart from the COVID-19 Fear Scale and colour vision subscale of the NEI-VFQ-25, all scale scores were worse in IIH patients than in healthy control subjects. Patients with severe visual field defects had higher HIT-6 scores (p = .036). Both vision-specific and overall QOL was reduced in patients with IIH. Headache severity and disability were more prominent in patients with severe visual loss. Fear caused by the COVID pandemic was not different in IIH patients than in healthy control subjects.

Abstract
Abstract
In this study, we have proposed an analytical method for calculating the specific heat capacity of uranium nitride nuclear material. The specific heat capacity results have obtained by the use of the Debye-Einstein approximation. The thermal conductivity of nuclear material has been obtained by using the experimental data of thermal diffusivity and the calculation results of specific heat capacity. This method shows that our results are satisfactory for the wide range temperature variations. The proposed approach can be easily applied to determine the thermodynamic properties of the other nuclear materials.

Abstract
In this study, it was aimed to prospectively evaluate the efficacy, side effects and seroconversion data of inactive severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), CoronaVac® (Sinovac, China) vaccine in healthcare workers. A total of 1053 healthcare workers who were initially seronegative (COV2T® SARS-CoV-2 Total Siemens, USA) and vaccinated with inactivated SARS-CoV-2 were included in the study. Quantitative IgG antibodies (ADVIA Centaur® SARS-CoV-2 IgG, Siemens, USA) were investigated 28 days after the first vaccine (n= 939) and the second vaccine (n= 771). In addition, neutralizing antibodies were evaluated via "enzyme linked immunosorbent assay (ELISA)" test (ACE2-RBD Neutralization Assay, Dia-Pro, Italy) 28 days after the first vaccine. Antibody response of the vaccine was evaluated statistically by univariate (Chi-square, Fisher's exact test, Student's t test, Mann-Whitney U, one-way ANOVA and Kruskall Wallis ANOVA tests) analysis and linear regression models. The consistency between quantitative IgG test and neutralizing antibody test was also evaluated in blood samples taken 28 days after second vaccination. Statistical analysis was determined in logarithmically transformed data with statistical analysis with SPSS 23.0 and Stata, and type 1 error level was accepted as 0.05. At least one side effect was reported by 31.3% and 26.8% of the participants after the first and second vaccine, respectively. The most frequent side effect was pain at the injection site with a frequency of 20.4% vs 21.7%. The frequency of applying to a health center due to side effects was 1.0% after the first vaccine and 0.8% after the second vaccine. The percentage of those who produced sufficient quantitative IgG was found as 25.3% (95% CI= 22.5-28.1) 28 days after the first vaccine and 97.9% (95% CI= 96.91- 98.93) after the second vaccine. Neutralizing test antibody positivity was found as 97.7% 28 days after the second vaccine. In univariate analysis, the characteristics that significantly increased the quantitative IgG response against inactivated SARS-CoV-2 vaccine were young age (p<0.01), female gender (p<0.01), being a non smoker (p<0.001), not having a chronic disease (p= 0.019), having had the flu vaccine this year (p= 0.012), not being overweight or obese (p= 0.020), and having a SARS-CoV2 infection prior to vaccination (p<0.001). In addition, allied health personnel showed significantly lower antibody responses than the other workers (p<0.001). Multiple linear regression models revealed that, female gender, younger age, smoking and previous COVID-19 polymerase chain reaction test positivity significantly affected the quantitative IgG response after vaccination. A 99% agreement was found between the ELISA-based neutralizing antibody test and the quantitative IgG test (Kappa p= 0.783) performed on the 28th day after the second vaccination. CoronaVac® provides adequate antibody response in 25% of healthcare workers aged 18-64, after 28 days from a single vaccine, and 97% after 28 days from the second vaccine. Antibody response was significantly higher in younger ages, women, non-smokers, and those who had previously encountered SARS-CoV-2. Phase 3 and phase 4 results are needed to Show effectiveness of this vaccine in real life.

Abstract
BACKGROUND/AIMS We aimed to perform the validity and reliability analysis of the Turkish version of the Pediatric Nutritional Risk Score (PNRS). MATERIALS AND METHODS The study group consisted of 149 patients aged between 1 month and 18 years who were admitted to the hospital for at least 48 h. The patients' age, gender, anthropometric measurements, length of stay, admission diagnosis, daily body weights, food consumption, and pain status were recorded. Backward and forward translations into Turkish were done. PNRS was performed by two different physicians. The consistency of the PNRS results was evaluated to determine the validity of PNRS. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated. RESULTS Of all patients, 69 (46.3%) were female and 80 (53.7%) were male. The mean length of the stay was 7.3±4.0 days. The mean age of the patients was 51.9±63.6 months. The Kappa coefficient between the two physicians was 0.66. Weight loss was observed in 65.2% of the patients in the high-risk group and 25.4% in the low-risk group. The hospital malnutrition rate was 31.5%. A higher risk was identified in those with <50% food intake and more severe disease. The specificity, sensitivity, NPV, and PPV of PNRS were 82.1%, 77.8%, 92.0%, and 58.3%, respectively. CONCLUSION A good consistency suggests that the Turkish validation was achieved successfully. The power of PNRS to discriminate the patients with moderate-low risk of developing malnutrition is higher than the patients with high risk. PNRS is considered a valid and reliable tool to establish the risk of malnutrition in the hospitalized patients.

Abstract
CONTEXT Since autism spectrum disorder (ASD) is a lifelong disease and because of its nature, the negative effects of the disease on the quality of life (QoL) of caregivers as well as patients are incontrovertible. AIMS It was aimed to evaluate the effect of the variables related to both parents and children on the QoL scores of the parents of the children with ASD. SETTINGS AND DESIGN This is a causality analysis study. SUBJECTS AND METHODS Questionnaire on sociodemographic/disease-related variables, QoL in Autism Questionnaire-Parent Version (QoLA-P), autism behavior checklist and Clinical Global Impression scale were assessed of 162 patients with ASD. STATISTICAL ANALYSIS USED Unpaired t- test, Mann-Whitney U test, Kruskal-Wallis test, and one-way ANOVA test were used for comparing groups. The parameters found to be statistically significant for QoLA-P in different analyses were included as the independent variable in the logistic regression analysis. The backward (variable elimination) model was selected as the model in the analysis. RESULTS The causality has been established may be stated as the severity of autism, the presence of psychiatric disorder in the mother/father, attendance of the child at school, duration since the diagnosis of autism, and the child's medication use. CONCLUSIONS Autism affects the QoL of caregivers. The intervention of treatment by considering the factors that affect the QoL positively or negatively may increase the QoL of caregivers.

Abstract
Aim We aimed to evaluate the effects of the severity and symptoms of congenital heart disease and the emotional and behavioral problems of affected children on their quality of life. Material and Methods The study was performed by interviewing 80 children aged between 6 and 16 years (40 with cyanotic heart disease and 40 with acyanotic disease) and their mothers. A sociodemographic data form, quality of life questionnaire, strength and difficulties questionnaire, and family life and parenting attitudes scale were used in the research. Life quality was the dependent variable of this research. Results No significant relation was found between age, sex, and education level of the parents and all quality of life subscale scores (p>0.05). In terms of quality of life, total quality of life subscale, emotional well-being and self-esteem subscales were significantly lower in children with cyanotic congenital heart disease (p=0.02, p=0.007, p=0.006, respectively). The total quality of life subscale was significantly lower in children with a medical treatment and surgical history. In terms of clinical symptoms, self-esteem, friendship and school life quality subscales were affected in the presence of dyspnea. As scores from strength and difficulties questionnaire increased, which is used for the assessment of children's psychological symptoms, all quality of life scores were significantly lowered except for school and family subscales. Conclusion It was found that symptoms of congenital heart disease affected the psychosocial quality of life subscales rather than the physical subscales. In addition, it was observed that mental symptoms in both the mother and child negatively affected quality of life rather than disease-related parameters.

Abstract
In this paper, we present a new analytical method to evaluate the temperature dependence of the thermal line shift and thermal line width of spectral lines in the Raman process using a simple approximation for the Debye functions. The proposed formulae guarantee the accurate and fast calculation of the thermal line shift and thermal line width. As an example of application, the analytical expression obtained is used to calculate the line shift and line width of the 2 E → 4 A2 transitions in V2+ :MgO at temperatures from 0 K up to 500 K. This analytical evaluation shows that our results are satisfactory for the wide range temperature variations.

Abstract
OBJECTIVE The aim of this paper is to present the validity and reliability of the Turkish version of the add-on module for the WHOQOL measures of quality of life for use with adults having physical or intellectual disabilities known as the WHOQOL-DIS. METHODS Data were collected from 150 Intellectual Disabled (ID) and 157 Physically Disabled (PD) persons in Turkey (Izmir) participating center of the global WHOQOL-DIS project. WHOQOL-DIS module is consisted of 12 disability specific items in addition to 26 generic items of WHOQOL-Bref. The proposed factorial structure (3 factors) of WHOQOL-DIS global study used in the psychometric analyses of the Turkish versions of WHOQOL-DIS. Reliability analyses and construct validity was tested via CFA analyses and convergent and discriminant validity analyses were assessed in relation to SWLS and WHODAS-II respectively. RESULTS Cronbach alpha values of the WHOQOL-DIS factors were as follows for ID and PD samples respectively: Factor 1 (Discrimination and support)= 0.54 and 0.64; Factor 2 (Independence)= 0.78 and 0.79 ; Factor 3 (Community participation)= 0.88 and 0.83. CFI and RMSEA values were 0.98 and 0.065 for ID sample and 0.98 ve 0.064 for PD sample respectively. Convergent-discriminant validities were satisfactory for all factors in PD group (r= 0.27 - 0.62) whereas Factor 1 was not found discriminative in the ID group (r= 0.09 -0.10). CONCLUSION Psychometric properties provided satisfactory evidence of reliability and validity of the Turkish version of WHOQOL-DIS. Nevertheless the results of Factor 1 (Discrimination and support) in ID persons should be interpreted with caution.

Abstract
Background Our purpose is to examine the relationship of Health related quality of life measured by EORTC QLQc30, QLQ-LC13; FACT-L, LCSS, Eq5D) with survival in advanced lung cancer patients. A total of 299 Lung Cancer (LC) patients were, included in this national multicenter Project entitled of “the LC Quality of Life Project (AKAYAK). Baseline scores were analyzed by using Cox’s proportional hazard regression to identify factors that influenced survival. Univariate and multivariate models were run for each of the scales included in the study. Results Mean and median survival were 12.5 and 8.0 months respectively. Clinical stage (as TNM), comorbidity; symptom scales of fatigue, insomnia, appetit loss and constipation were associated with survival after adjustment for age and sex. Global, physical and role functioning scales of QLQc30; physical and functional scales of LCS and TOI of the FACT-L was also associated with survival. Mobility and Usual activities dimensions of the Eq5D; Physical functioning and the constipation symptom scale of the QLQ-c30; and LCS and TOI scores of the FACT-L remained statistically significant after adjustment. LC13 and LCSS scales were not predictors of survival. Conclusions HRQOL serves as an additional predictive factor for survival that supplements traditional clinical factors. Besides the strong predictive ability of ECOG on survival, FACT-L and the Eq5D are the most promising HRQOL instruments for this purpose.

Abstract
Introduction Experimental and clinical studies demonstrated that the renin-angiotensin system (RAS) affects the pathogenesis of atherosclerosis and prognosis of coronary heart disease (CHD). The aim of this study was to investigate the genotype distribution and the allele frequencies of three RAS genes polymorphisms and their effects on premature CHD in a Turkish population. Materials and methods One-hundred and fifteen Turkish patients with premature CHD and 128 controls were included into the study. Angiotensin-converting enzyme (ACE), angiotensin II type 1 (AT1) receptor and angiotensinogen (AGT) gene polymorphisms were analysed by polymerase chain reaction (PCR ) and restriction fragment length polymorphism (RFLP). Results The patients group showed an increased frequency of the ACE D allele compared with controls (65% vs. 35%, p=0.0001). There was a significant association between the DD genotype and premature CHD (ACE DD vs. ID and II; odds ratio [OR]=2.82 [CI 95% 1.33—2.91, p=0.002]). Also, we observed increased premature CHD risk associated with higher frequencies of the AGT MM genotype in patients when compared with controls (AGT MM vs. TT and MT, OR=1.92 [CI 95% 1.11—3.33, p=0.018]). We found a significant association between AT1-receptor AA genotype and decreased risk of premature CHD (AT1R AA vs. AC and CC, OR= 0.57[CI 95% 0.34—0.95, p=0.03]). Conclusions We demonstrated that increased premature CHD risk is associated with higher frequencies of the ACE DD and AGT MM genotypes. These findings indicate a synergistic contribution of ACE DD and AGT MM polymorphisms to the development of premature CHD. Also, our results suggest that family history, smoking, diabetes, hypertension, obesity and ACE DD genotype were independent risk factors for premature CHD.

Abstract
PURPOSE The objective of this study was to assess the reliability and validity of the Oncology module of the generic KINDL scale (having 24 items with 6 domains). METHODS The psychometric properties of the KINDL Oncology module were evaluated from the aspect of internal consistency, reliability, and construct validity on an inpatient sample of 103 Turkish children (mean age 10.0 ± 4.01 years) who had various oncological disorders. RESULTS The KINDL Oncology module (24 items) showed acceptable α coefficients ranging from .57 (physical well-being) to .87 (treatment) for each domain. In confirmatory factor analysis of the original 4-domain structure, Root Mean Square Error of Approximation was found as .086, and Comparative Fit Index was .87. Good known groups results supported the construct validity of the instrument. Correlations between the domains of the mother KINDL and the domains of its oncology module were significantly high, indicating a satisfactory convergent validity. CONCLUSION The Turkish version of the KINDL Oncology module showed good reliability and questionable validity in this study. However, further research on other language versions of the module is needed for its global use.

Abstract
OBJECTIVE Postpartum period is physically, socially and emotionally a difficult time for the parents and the baby to become a family. We tried to investigate how the anaesthesia method affects patients who underwent cesarean delivery, as a factor which also affects this period. METHODS Two hundred and six parturients, who underwent elective cesarean delivery in Celal Bayar University Hafsa Sultan Hospital were recruited for our study. After demographic data and anaesthesia methods were noted, an EQ-5D health survey and Katz ADL scale were evaluated face to face 24 hours postoperatively, and by telephone on the 5th postoperative day. RESULTS The percentage of patients who had general anaesthesia was 35.2% (n=71), while 19.8% (n=40) had epidural anaesthesia and 45% (n=91) had spinal anaesthesia. Among -these three methods, the EQ-5D health survey revealed that the outcome at postoperative 24 hours was best in epidural anaesthesia and that general anaesthesia outcome was the worst (p=0.007). The Katz ADL scale at postoperative 24. hours showed that epidural anaesthesia was better than the other methods for regaining daily life activities (p<0.05). CONCLUSION Our study showed that epidural anaesthesia had the most effective role among the methods in regaining daily life activities after elective cesarean delivery, which was demonstrated using the EQ-5D health survey and Katz ADL scale.

Quality of life assessment in women with breast cancer: a prospective study including hormonal therapy. J Breast Cancer 2013; 16:220-8. [PMID: 23843857 PMCID: PMC3706870 DOI: 10.4048/jbc.2013.16.2.220] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2013] [Accepted: 05/29/2013] [Indexed: 12/04/2022] Open
Abstract
Purpose Evaluating the effect of hormonal treatment on quality of life (QoL) in breast cancer patients by using the Functional Assessment of Cancer Treatment (FACT) questionnaire is the main purpose of this trial. Methods Breast cancer patients treated with adjuvant between January 2007 and December 2009 were evaluated. The first survey was done after patients completed their whole adjuvant treatment except for the hormonal therapy and this was as 'basal assessment.' The second survey was done 6 to 12 months after the basal surveys during their routine policlinic controls. The last survey was done within the last 18 to 24 months of the follow-up period. Results The effect of marital status, number of pregnancies, residence in the village or city, hemoglobin levels, chemotherapy and hormonal therapy for any other reason except for breast cancer on the QoL could not be seen. Endocrine subscale scores were detected to be higher in patients aged >60 years than in younger ones. The other dimension scores were low in the elderly patient group. There was a statistically significant relationship between being >30 years old and improvement in the social well-being score (p=0.028). The functional well-being scores were found to be significantly higher in the patient group that had no comorbid disease (p=0.018). Endocrine subscale scores were statistically worse in patients who had psychiatric disease (p=0.057) but the general QoL data were similar with others. It was shown that all QoL scores for all dimensions had statistically significant changes (p<0.001) in terms of hormonal regimes. Conclusion The diagnosis of breast cancer was found to be an independent factor that affects social well-being and social life in a negative way. We must give attention to complaints including complaints about sexual life and hormonal status in order to ensure compliance of patients with the required hormonal regimens. By the help of future research, we can improve the prognosis of this disease through increased treatment adherence and belief of patients.

Challenges in access to health services and its impact on quality of life: a randomised population-based survey within Turkish speaking immigrants in London. Health Qual Life Outcomes 2012; 10:11. [PMID: 22280521 PMCID: PMC3275503 DOI: 10.1186/1477-7525-10-11] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2011] [Accepted: 01/26/2012] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND AND AIM There are a significant number of Turkish speaking immigrants living in London. Their special health issues including women's health, mental health, and alcohol and smoking habits has been assessed. The aim of this study was to explore the ongoing challenges in access to health care services and its impact on Quality of Life of immigrants. MATERIAL AND METHODS This cross-sectional population-based study was conducted between March and August 2010 with Turkish immigrants (n = 416) living in London. Of these, 308 (74%) were Turkish and 108 (26%) were Turkish Cypriots. All healthy or unhealthy adults of 17-65 years of age were enrolled. A structured questionnaire with 44 items in five subcategories and 26-items WHOQOL BREF were used. RESULTS Mean duration of stay for Turkish Cypriots (26.9 ± 13.9 years) was significantly longer than Turkish immigrants (13.3 ± 7.5) (p < 0.001). Turkish immigrants (n = 108, 36.5%) need interpretation more often when using health services than Turkish Cypriots (n = 16, 15%) (p < 0.001). Multivariate analyses suggested significant effects of older age, non-homeownership, low socioeconomic class, poor access to health services, being ill, poor community integration and being obese on physical well-being and also significant effects of low income and poor community integration on perceived overall Quality of Life (WHOQOL) of the participants. CONCLUSIONS The results of this study demonstrate how the health and well-being of members of the Turkish speaking community living in London are affected by social aspects of their lives. Providing culturally competent care and interpretation services and advocacy may improve the accessibility of the health care.

Abstract
OBJECTIVE The purpose of this study was to describe the psychometric properties of the Myocardial Infarction Dimensional Assessment Scale (MIDAS). METHODS This is a methodological cultural adaptation study. The MIDAS consists of 35-items covering seven domains: physical activity, insecurity, emotional reaction, dependency, diet, concerns over medication, and side effects which are rated on a five-point Likert scale from 1: never to 5:always. The highest score of MIDAS is 100.Quality of life (QOL) decreases as the score of scale increases. Overall 185 myocardial infarction (MI) patients were enrolled in this study. Cronbach alpha was used for the reliability analysis. The criterion validity, structural validity, and sensitivity analysis approach was used for validity analysis. New York Heart Association (NYHA) and the Canadian Cardiovascular Society Functional Classifications (CCSFC) for testing the criterion validity; SF-36 for construct validity testing of the Turkish version of the MIDAS were used. RESULTS The range of Cronbach alpha values is 0.79-0.90 for seven domains of the scale. No problematic items were observed for the entire scale. Medication related domains of the MIDAS showed considerable floor effects (35.7%-22.7%). Confirmatory Factor analysis indicators [Comparative Fit Index (CFI) =0.95 and Root Mean Square Error of Approximation (RMSEA) =0.075] supported the construct validity of MIDAS. Convergent validity of the MIDAS was confirmed with correlation of SF-36 scale where appropriate. Criterion validity results was also satisfactory by comparing different stages of the NYHA and the CCSFC (p<0.05). CONCLUSION Overall results revealed that Turkish version of the MIDAS is a reliable and valid instrument.

Abstract
This paper describes the development of a Quality of Care and Support (QOCS) scale for use with adult persons with physical and intellectual disabilities. In the pilot phase of the study, 12 centers from around the world carried out focus groups with people with physical and disabilities, their carers, and with professionals in order to identify themes that were relevant for their quality of care. Items generated from the focus groups were then tested in a pilot study with 1400 respondents from 15 different centers worldwide, with items being tested and reduced using both classical and modern psychometric methods. A field trial study was then carried out with 3772 respondents, again with the use of both classical and modern psychometric methods. The outcome of the two rounds of data collection and analysis is a 17-item module for assessment of quality of care in physically or intellectually disabled people. Further modifications are also proposed for the use of the QOCS with adults with intellectual disabilities, including simplification of wording of some of the items, the use of a three-point response scale, and the inclusion of smiley faces.

Abstract
The aim of the study was to test Turkish validity and reliability of Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) in patients with chronic venous insufficiency (CVI). A total of 118 patients with CVI hospitalized in 3 different hospitals were enrolled in this study. VEINES-QoL/Sym, translated to Turkish with a standard methodology, was applied to the patients and was evaluated for acceptability, reliability, validity, and responsiveness. Cronbach α (including if item deleted) values were used for the reliability analysis. Construct and criterion validity approaches were used for validity analysis. Cronbach α values are .86 for the VEINES-QOL and .81 for the VEINES-Sym. No problematic items were observed for the scale. The VEINES-QoL/Sym was significantly sensitive to clinical, etiology, anatomy, and pathophysiology (CEAP) classification, indicating good criterion validity. Significant correlation was found between scores of SF-36 and VEINESQoL (r = .43-.66). Turkish version of the VEINES-QOL/Sym was found reliable and valid for Turkish patients with CVI.

Abstract
PURPOSE To test the validity and reliability of The European Organization for Research and Treatment of Cancer (EORTC) core (QLQ-C30) and breast cancer module (QLQ-BR23) for Turkish breast cancer patients. PATIENTS AND METHODS A total of 127 patients treated with radiotherapy (RT) enrolled to this prospective study. EORTC QLQ-C30 and QLQ-BR23 modules applied to patients before initiation of RT and at follow-up period. Statistical analyses were performed by SPSS 13.0. RESULTS Questionnaires' were found reliable and valid for Turkish breast cancer patients. Six of the 8 multi-item scales of QLQ-C30 had a high reliability (Cronbach's ? >0.7); where physical functioning and pain scores were less reliable (Cronbach's ? of 0.66 and 0.68 respectively). In the QLQ-BR23, 3 of 5 multi-item scales were reliable; less reliable were breast and arm symptoms scale (Cronbach's ? of 0.65 and 0.61 respectively). In our analysis the most determinative subscales of QLQ-C30 on global health was emotional functioning followed by fatigue, role functioning and appetite loss (respectively p=0.002, p=0.01; p=0.03 and p=0.08). Among QLQ-BR23 scales systemic therapy SIDE effects, future perspective and upset by hair loss subscales had high impact on global health status (respectively p=0.006; p=0.01 and p=0.03). CONCLUSIONS The Turkish version of EORTC QLQ-C30 and QLQ-BR23 modules are reliable and valid tools to assess quality of life of Turkish breast cancer patients.

Abstract
OBJECTIVE Any disease specific Health Related Quality of Life Instrument for Chronic Heart Failure (CHF) is lacking in Turkey. The aim of this study is to adapt the Chronic Heart Failure Questionnaire (CHQ) into Turkish and probe the reliability and validity of this questionnaire. METHODS There are four dimensions of this 20 items scale. These dimensions are: dyspnea (5 items), fatigue (4 items), emotional status (7 items) and mastery (4 items). Response options were evaluated using a 7 -point Likert type scale. Quality of life (QOL) improves as the score increases. A total of 205 CHF patients hospitalized in the Department of Cardiology of Ege University hospital were enrolled in this study. The CHQ was applied to the patients twice with a wash-out period of 15 days. Confirmatory approach was used during the reliability and validity analysis. Cronbach alpha test was used for the reliability analysis. Confirmatory factor analysis (CFA) was used for the construct validity testing. NYHA classification for testing the criterion validity; SF-36 and WHOQOL-100 General Health and QOL facet for convergent validity testing of the Turkish version of the CHQ were used. Responsiveness to change was evaluated by Effect Size analysis by using test-retest data. RESULTS The range of Cronbach alpha values is 0.72-0.94. A considerable ceiling and floor effects were observed for the dyspnea dimension of the scale but no problematic items were observed for the entire scale. The CFA results supported the original four factors scale structure. Criterion and construct validity rebuts were satisfactory. Effect sizes obtained among dimensions of the CHQ were between 0.13 and 0.56. CONCLUSION Overall results revealed that Turkish version of the CHQ is a reliable and valid instrument to be used for the evaluation of CHF patients.

Abstract
The aim of this study is to test the psychometric properties and the responsiveness of the original (status) version of Turkish DTSQ. The study sample included 88 patients with diabetes mellitus who were evaluated in three consecutive time points. The first data collection time point was during their initial contact to the clinic, and the two following (3rd month and 6th month) were during the monitoring visits to the Celal Bayar University Endocrinology Department in 2007. After the adaptation of the DTSQ to Turkish language by following standard procedures, this instrument was applied to the patients along with WBQ-12 and World Health Organization Quality of Life Measure (WHOQOL-Bref). The reliability of the DTSQ was evaluated by running internal consistency analysis (Cronbach Alpha) and item analysis. Construct validity of the instrument was evaluated by various tests such as Principal Components analysis, Confirmatory Factor Analysis, Concurrent validity and "Known Groups" comparisons. Finally the sensitivity (responsiveness to change) of the DTSQ scores to the changes of the metabolic conditions were assessed. 50.0% of the participants were male with a mean age of 51.1 ± 11.4 (min 22, max 78). Majority of them had type 2 diabetes (86.4%) and 72.7% of these patients had at least one co-morbid chronic conditions. While 53.4% of the patients had been treated by insulin the remaining 46.6% had been taking oral anti-diabetic agents. The results revealed satisfactory alpha values for DTSQ (α > 0.70). All of the three metabolic measures (i.e., FBG, PBG, and HbA1c) had significant correlations with the DTSQ scores. The criterion and construct validity of the scale were found to be very satisfactory. The Turkish version of the DTSQ showed acceptable fit indices (RMSEA = 0.03, CFI > 0.90) with the original (hypothetic) construct. Almost all of the sub-dimensions of the WBQ and WHOQOL were correlated with the DTSQ as expected, indicating a good concurrent validity. DTSQ status version was found to be a reliable and valid instrument for the assessment of treatment satisfaction in Turkish diabetes mellitus patients.

Abstract
The aim of this study was to analyze the agreement between self and proxy reports of quality of life (QoL) in people with intellectual disabilities and to examine the factors which contribute to these differences. The study was conducted across six international centres in a sample of 614 adults with intellectual disabilities as well as two different samples of proxies (N=874) including both professional carers and relatives. QoL was assessed with the disability version of the WHOQOL-BREF. In both proxy samples results show a significant moderate association between the persons' QoL-assessment and the assessment of their proxies in all of the five QoL domains. There were significant mean differences in most items which varied in their direction. In general, people with disabilities rated their QoL higher than their proxies except for two items from the physical domain. The factors which most significantly contributed to these differences were proxy knowledge of the person as well as the WHODAS-disability score. Cross-cultural differences in the magnitude of concordance were observed. As a conclusion, the study shows a good agreement between the person-proxy QoL-assessments, and that the factors associated with disagreement are limited in this study. Future studies should elaborate the stability of concordance over time.

Abstract
PURPOSE To determine the psychometric properties of the Turkish version of the World Health Organization Quality of Life Instrument-Older Adults Module (WHOQOL-Old). METHODS The Turkish version of the WHOQOL-OLD was administered to 527 older (> 65 years) adults living in urban, suburban, and rural areas of Manisa Province, Turkey. The WHOQOL-OLD module consists of 24 items assigned to 6 facets (sen------sory abilities, autonomy, past, present and future activities, so-cial participation, death and dying, and intimacy) and is a supplementary module of WHOQOL-BREF. The WHOQOL-BREF and GDS-30 were also administered to the participants. A confirmatory approach was used during reliability and validity analysis. SPSS v.10.0 and LISREL v.8.54 were used for analysis. RESULTS Mean age of the participants was 71.06 +/- 5.20 years and the overall WHOQOL-OLD score was 56.02 +/- 11.86. In all, 54.5% of the participants were female and 60.5% reported to be in poor health. Both ceiling and floor effects of the WHOQOL-OLD were satisfactory (< 0.05%). Alpha values for the facets and overall scale (range: 0.68-0.88) (> 0.70), and item total correlations and overall scale success were satisfactory. As a measure of the construct validity of the scale, confirmatory factor analysis showed very high CFI values (range: 0.936-0.999) for each of the domains. Convergence of WHOQOL-OLD facet scores on WHOQOL-BREF domains and WHOQOL-OLD were very fine in general. CONCLUSIONS The psychometric properties of the Turkish version of the WHOQOL-OLD were acceptable, indicating that the scale is reliable and valid for use with older Turkish adults (> 65 years).

Abstract
PURPOSE To test the validity and reliability of the Turkish version of the self-administered form of the National Eye Institute Visual Functioning Questionnaire (NEI-VFQ 25). METHODS Patients with no limitations to respond to a health status interview and affected by a chronic eye disease were enrolled. The Turkish versions of the abbreviated form of World Health Organization Quality of Life (WHOQOL-BREF) and the NEI-VFQ 25 instruments were administered to all participants. RESULTS The mean (SD) age of the participants was 60.9 (14.5) years. There were 61 patients with one of the following conditions: Cataract (57.4%), diabetic retinopathy (13.2%), age related macular degeneration (ARMD) (11.4%), glaucoma (9.8%) and degenerative myopia (8.2%). The Cronbach alpha of the overall scale was 0.97; the Cronbach alpha ranged from 0.94 to 0.78 for the subscales. The physical, psychological, environmental and social domains of the WHOQOL-BREF had fair to good correlations with the NEI-VFQ 25 (r = 0.68 to r = 0.26), which indicated a sufficient convergent validity. Patients with lower visual acuity (VA) had lower index scores than those with higher VA (p = 0.001), which showed a sufficient responsiveness. CONCLUSION Statistical analysis showed that Turkish version of the NEI-VFQ is a valid and reliable instrument to measure vision-related quality of life in patients with chronic eye diseases.

Abstract
The aim of this study was to develop a Turkish version of the Turkish Pediatric Rhinitis Quality of Life Questionnaire (PRQLQ) that is conceptually equivalent to the original and to evaluate its validity and reliability. The study included 102 children with allergic rhinitis (AR) aged 5 to 16 years. Demographic information, family history of allergy, and duration of AR were recorded. All patients completed the T4SS symptom score and PRQLQ. Reliability including internal consistency and item-total score correlations and validity analysis including Known Group method were performed. Activity limitations, emotional function and symptoms domains had successful Cronbach alpha scores of 0.62, 0.69 and 0.78, respectively. All items were significantly correlated with their own domain. Correlations of all the domain scores with the total score and the other domains were significant. Linear multiple regression reduced models revealed that both domain and total scores showed statistically significant sensitivity to T4SS. The Turkish PRQLQ is a valid and reliable measure for use in Turkish children with AR.

Abstract
The aim of this study was to adapt the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) into Turkish and to demonstrate its psychometric performance. After Turkish adaptation of the PAQLQ, this study was conducted on 122 children with asthma aged between 7 and 16 years. A sociodemographic form and PAQLQ and KINDL (a generic health-related quality of life instrument developed for children) questionnaires were applied. Reliability analysis consisted of internal consistency and item-total score correlations, while validity was tested by construct validity. Cronbach alpha scores for Activity (0.80), Symptoms (0.90), and Emotional (0.86) domains were satisfactory. Item versus subscale and total score correlations were significant. Correlations of total PAQLQ score with KINDL total and Physical and Psychological Well-Being domains were significant (r=0.33, 0.45 and 0.31 respectively, p<0.05 for all). Exploratory factor analysis revealed that 78.3% of the items were replaced in their original domain. This Turkish version of PAQLQ is a valid and reliable disease-specific health-related quality of life questionnaire.

Abstract
OBJECTIVE There are few health-related quality of life (HRQOL) instruments available that have been validated for use with Turkish children. The Kid-KINDL is a generic measure of children's (8-12 years) HRQOL, which contains 24 categorical items that assess 6 dimensions (physical well-being, emotional well-being, self-esteem, family, friends, and school). The Kid-KINDL is available in many languages. Following an elaborate translation procedure and cognitive focus group interviews, the Kid-KINDL was adopted into Turkish. This paper describes the psychometric properties of the new Turkish Kid-KINDL. METHODS In total, 1918 children aged 8-12 years at a school in Manisa completed the Kid-KINDL. A confirmatory approach was used for validity and reliability analysis. Using the Multi-trait/Multi-item analysis program (MAP) item-internal consistency and item-discriminant validity were calculated to confirm the instrument's structure. Likert scaling assumptions were tested and confirmatory factor analysis (CFA) was applied as well. After modification of 2 unsatisfactory items the Kid-KINDL was administered to a different group of 84 randomly selected children and the analyses were repeated. RESULTS Cronbach's alpha was 0.35-0.78 before and 0.54-0.78 after the scales was modified. MAP-scaling success was 60%-100% before and 90%-100% after the modification. CFA confirmed the Kid-KINDL structure for the original version (RMSEA = 0.077) was less than the modified version (RMSEA = 0.059), although for the latter the sample was rather small. Floor effects were negligible, and ceiling effects reached 19%. CONCLUSION The results indicate that the Turkish Kid-KINDL was a reliable and factorially valid assessment of the children's HRQOL. The modifications made to the 2 unsatisfactory items increased the psychometric quality of the scale.

An evaluation of quality of life of mothers of children with enuresis nocturna. Pediatr Nephrol 2008; 23:93-8. [PMID: 17899206 DOI: 10.1007/s00467-007-0605-0] [Citation(s) in RCA: 42] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2006] [Revised: 07/08/2007] [Accepted: 07/10/2007] [Indexed: 10/22/2022]
Abstract
The aim of this study was to evaluate the impact of enuresis nocturna on quality of life of the mothers. Mothers who have a child with monosymptomatic nocturnal enuresis (n=28) and mothers who have a child without any health problems (n=38) were enrolled in the study. Groups were in balance for background variables (child's age, gender, and number of siblings; mother's age, marital status, highest year of education completed, and occupation; presence of health insurance; and type of residence). Short-Form Health Survey (SF-36) Questionnaire, the Beck Depression Inventory (BDI), and Spielberg's State-Trait Anxiety Inventory (STAI) were applied to all mothers. The mothers of children with enuresis had significantly lower quality-of-life scores in the SF-36 for the bodily pain (p=0.015) and role emotional (p=0.014) subscales. We observed significant difference between groups according to BDI; mean score was higher in mothers who have a child with enuresis nocturna (p=0.017). There was no significant difference between groups according to the STAI. Significant differences according to bodily pain and role emotional subscales of SF-36, and the BDI scores, show that the mothers were negatively affected by having a child with monosymptomatic nocturnal enuresis.

Abstract
OBJECTIVES To explore the differences in unwanted fertility in different parts of a city. METHODS Data were obtained from the 1999 Manisa Demographic and Health Survey (MDHS) in Turkey. We collected information from a representative sample of 1728 ever-married women aged 15-49 years on fertility, fertility preferences, unmet need for family planning, contraceptive discontinuation, and abortion. Data were analyzed using SPSS 10.0 for Windows. RESULTS Of the persons studied, 1238 (71.6%) were living in urban settlements and 490 (28.4%) in suburban (gecekondu) settlements. The total fertility rate is higher among gecekondu women (2.42) than among urban women (2.14) although gecekondu women have a lower wanted fertility rate (1.54) than urban women (1.77). Married women in the urban area were currently using a contraceptive method more frequently (75.6%) than those living in the gecekondu area (61.7%) (OR 2.5; 95% CI 1.9-3.2; p < 0.001). The unmet need percentage in gecekondu women (17.7%) is higher than in urban women (8.3%; p < 0.001). The induced abortion rate is higher in urban women (14.8 per 1000 pregnancies) than in gecekondu women (7.1 per 1000 pregnancies; OR 2.1; 95% CI 1.4-3.1; p < 0.001). CONCLUSIONS There are inequalities in the achievement of fertility preferences and in accessibility to family planning services between urban and suburban parts of the city.

Abstract
Decreased quality of life is often an important cause or consequence of psychiatric illness, and needs to be included in a comprehensive treatment plan. The authors aimed to identify how psychiatric patients characterize the quality of their lives compared to others who are suffering from a chronic physical illness (diabetes) and healthy individuals. A total of 100 psychiatric patients were recruited from Dokuz Eylül University Psychiatry Department outpatient clinic. Of these, 34 had 4(th) edition Diagnostic and Statistical Manual diagnosis of alcohol dependence, 38 had schizophrenia, and 28 had bipolar disorder. A total of 35 patients with diabetes and 49 healthy individuals were also included in the study. The World Health Organization's Quality of Life Questionnaire was used to measure the quality of life. Patients with alcohol dependence, bipolar disorder, and schizophrenia scored lower than healthy subjects on the physical aspects of quality of life. Patients with schizophrenia had lower scores in the psychological domain compared to patients with bipolar disorder, patients with diabetes, and healthy subjects. In the social relationship domain, patients with schizophrenia and alcohol dependence scored lower compared to healthy subjects. Patients with schizophrenia were worse with respect to social relationships than bipolar patients and diabetics. World Health Organization's Quality of Life Questionnaire is useful for evaluating the needs and targets for interventions in psychiatric patients.

Abstract
BACKGROUND The aim of this study was to test the linguistic validation of the Turkish version of the Dermatology Life Quality Index (DLQI) for Turkish speaking dermatology patients. METHODS The DLQI is a 10-item dermatology specific index developed originally in English. The methodology of this study consists of four consecutive sections: Translation, cognitive debriefing, field testing and statistical analysis. Translation steps: (a) Two forward independent translations into Turkish, (b) reconciliation of these translations by a dermatologist, (c) backward translation of the consensus Turkish version by a bilingual person into its original language (English), (d) and comparing the original questionnaire with the backward translated one. Cognitive debriefing: Sessions were performed on five patients from each of the seven different dermatological diagnosis groups. Field testing: The final Turkish version on which the face validity was approved by specialists on a total of 79 inpatients/outpatients with various dermatological diagnoses treated at Celal Bayar University Hospital. STATISTICAL ANALYSIS Internal consistency (using Cronbach a) and item-total score correlations (Pearson correlation) were used for reliability analysis. Validity analysis was carried out by construct testing (principal components factor analysis), convergent (Pearson correlation) and (discriminate Student's t-test and Mann-Whitney U-test) validity, and SF-36 was used in parallel with DLQI in order to test convergent validity. The data were analyzed by the SPSS version 10.0 (SPSS Inc., Chicago, IL, USA) statistical package. RESULTS The mean age of the patients in the study was 30.77+/-15.91 years; the mean score of DLQI was 7.61+/-6.12. The median of item-total correlation coefficient was found to be 0.66, within a range of 0.48-0.81. The internal consistency of the index was found to be highly sufficient (alpha=0.85). The DLQI was found to be highly related to the physical domain of SF-36. Life quality score was found to be significantly low for the inpatients compared with outpatients (differential validity). CONCLUSION It was found that the Turkish version of the DLQI was an acceptable index for dermatologists and dermatology patients and, moreover, to be valid and reliable in a cross-sectional level. The responsiveness of the Turkish version of the DLQI needs to be tested further on a variety of dermatological conditions with different severities.

Abstract
OBJECTIVES The cognitive subscale of the Alzheimer's Disease Assesment Scale (ADAS-Cog) is the most widely used test in clinical trials dealing with Alzheimer's disease (AD). The aim of this study was to investigate the validity and reliability of the Turkish version of ADAS-Cog. METHODS Twenty-nine patients with AD, fulfilling NINCDS-ADRDA criteria of probable AD, who were in stage 3-5 according to the Global Deterioration Scale (GDS), and 27 non-demented control subjects with similar age, gender and educational status were recruited for the study. The Turkish version of ADAS-Cog, Standardized Mini Mental Status Examination (MMSE) and Short Orientation-Memory-Concentration Test (SOMCT) were applied to both of the groups. Inter-rater reliability, internal consistency, test-retest reliability; face validity, differential validity and convergent validity were statistically analyzed. RESULTS Both MMSE and ADAS-Cog have significantly differentiated patients with AD and control subjects (p < 0.001). A significant correlation was established between MMSE and ADAS-Cog scores in AD group (r: -0.739). ADAS-Cog was also highly significantly correlated with GDS (r: 0.720) and SOMCT (r: 0.738). For the group with AD, control and whole cohort coefficients of internal consistency, Cronbach's alpha: 0.800, 0.515, 0.873 were found respectively. Inter-rater reliability for total ADAS-Cog score was found as ICC: 0.99 and 0.98 and test-retest reliability was found as ICC: 0.91 and 0.95 for demented and nondemented subjects, respectively. CONCLUSION The Turkish version of ADAS-Cog has been found to be highly reliable and valid in differentiating patients with mild and moderate AD from nondemented subjects.

Abstract
The purpose of this study was to demonstrate the relationship between body weight and HRQOL in a representative sample of nonpregnant women in reproductive age period. The data of this cross-sectional study was extracted from a survey: Manisa Demographic and Health Survey (MDHS) conducted in Manisa city in 2000. The study population of MDHS is a representative sample of 1602 reproductive (15-49) age women. World Health Organization Quality of Life Questionnaire abbreviated version (WHOQOL-BREF), which was composed of four domain factors (physical, psychological, social relations and the environment), was used to assess HRQOL. Each of four domains had a possible score ranged between 0 (poor HRQOL) and 20 (excellent HRQOL). The mean age of the women was 35.29+/- 8.19 years. Among them, 35.8 % had normal weight (BMI 18.5 to 24.9), 32.3 % were overweight (BMI 25.0 to 29.9) while 31.9 % were moderate and 3.4% were morbidly obese. After adjusting for age, level of education and co-morbid illnesses, subjects with a BMI higher than normal value, had significantly lower HRQOL scores, compared to normal-weight individuals on each of the domains, except for the environmental domain. Our results suggested that the body weight alone could negatively affect HRQOL. In other words, obesity not only increased the risk of morbidity and mortality, but also affected the perceived health and life quality negatively. In conclusion, in addition to age, socioeconomic status and co-morbid illnesses, body weight should also be controlled in studies examining HRQOL.
