A cross-cultural study of spirituality, religion, and personal beliefs as components of quality of life

This paper reports on an international study in 18 countries (n=5087) to observe how spirituality, religion and personal beliefs (SRPB) relate to quality of life (QoL). SRPB is assessed using the World Health Organization's QoL Instrument (the WHOQOL), where eight additional facets were included to more fully address these issues as they pertain to QoL, along with physical, social, psychological and environmental domains. The facets address issues such as inner peace, faith, hope and optimism, and spiritual connection. The results showed that SRPB was highly correlated with all of the WHOQOL domains (p<0.01), although the strongest correlations were found with psychological and social domains and overall QoL. When all of the domain scores were entered into a stepwise hierarchal regression analysis, all of the domains contributed to overall quality of life (N=3636), explaining 65% of the variance. When this was repeated for those people who reported poor health (N=588), it was found that only four domains explain 52% of the variance. The first was the level of independence, followed by environment, SRPB and physical. Gender comparisons showed that despite showing lower scores for facets in the psychological domain, such as negative feelings and poorer cognitions, women still reported greater feelings of spiritual connection and faith than men. Those with less education reported greater faith but were less hopeful. It is suggested that SRPB should be more routinely addressed in assessment of QoL, as it can make a substantial difference in QoL particularly for those who report very poor health or are at the end of their life.     

Use of the MQoL-HIV with asymptomatic HIV-positive patients

The purpose of this study was to determine the appropriateness of the recently developed Multidimensional Quality of Life Questionnaire for HIV/AIDS (MQoL-HIV) as a measure of quality of life (QoL) in cases of asymptomatic human immunodeficiency virus (HIV) infection. The MQoL-HIV is a 40-item instrument measuring ten domains (mental health, physical health, physical functioning, social functioning, social support, cognitive functioning, financial status, partner intimacy, sexual functioning and medical care) relevant to HIV infection. An overall QoL score, the MQoL-HIV Index, is a weighted composite of two domain scores. In a sample of 216 HIV-infected men and women, the MQoL-HIV distinguished acquired immune deficiency syndrome (AIDS), symptomatic and asymptomatic cases in overall QoL and in seven individual QoL domains. The index was responsive to perceived QoL changes over 5.5 months (r = 0.52). We also found the MQoL-HIV was less susceptible to ceiling effects in asymptomatic cases than was the Medical Outcomes Study (MOS) SF-20. These results suggest that the MQoL-HIV is a valid and reliable measure of QoL for both asymptomatic and symptomatic HIV infection.     

Time-Restricted Eating Improves Quality of Life Measures in Overweight Humans

Time-restricted eating (TRE) reduces weight in humans, but its effects on quality of life have not been well characterized. By performing a secondary analysis of a randomized clinical trial, we examined the effects of TRE (12-week intervention, 8 h eating window) vs. non-TRE (unrestricted eating) on quality of life (QoL) measures. Twenty subjects with overweight and prolonged eating window (mean (SD): 15.4 h (0.9)) were randomized to either 12 weeks of TRE (8 h eating window: (n = 11)) or non-TRE (n = 9). QoL data were collected with the 36-item Short Form Survey (SF-36) pre- and post-intervention. Given a two-way ANOVA model and post-hoc t-test analysis, the TRE group improved limitations due to emotional health post-intervention: +97.0 (10.0)) vs. baseline: +66.7 (42.2) (p = 0.02) and perceived change in health over the last year end intervention: +68.2 (16.2) vs. baseline: +52.3 (23.6) (p = 0.001) relative to baseline. The TRE group improved limitations due to emotional health TRE: +97.0 (10.0) vs. non-TRE: +55.6 (44.1) (p = 0.05) and perceived change in health (TRE: +68.2 (16.2) vs. non-TRE: +44.4 (31.6) (p = 0.04) relative to the non-TRE group at post-intervention (p < 0.025). In conclusion, 12 weeks of TRE does not adversely affect QoL and may be associated with modest improvements in QoL relative to baseline and unrestricted eating; these findings support future studies examining TRE compliance and durability.     

Changes in Health Status, Psychological Distress, and Quality of Life in COPD Patients after Hospitalization

The purpose of this paper was to describe quality of life (QoL) following an acute exacerbation of chronic obstructive pulmonary disease (COPD), and to examine possible relationships between QoL, health status, psychological distress and QoL. This prospective longitudinal study examined data from hospitalization and two subsequent phases, collected over a 9-month period. The sample consisted of 51 COPD patients aged 48–87 years. Health status was assessed with the St George’s Respiratory Questionnaire (SGRQ); psychological distress with the Hopkins Symptom Checklist (HSCL); and quality of life using the World Health Organization Quality of Life – Bref (WHOQOL – Bref). Health status improved significantly over the 9 months; from 65.95 to 59.40 (p = 0.001) in the SGRQ total score. Psychological distress improved significantly from hospitalization to the 1-month assessment (T2) (p = 0.001). QoL remained stable except for a significant increase in the physical domain from hospitalization to T2, and in the environmental domain from hospitalization to T2 and T3. Test–retest correlations of the WHOQOL – Bref were high. The results suggest an improvement in the health status over a 9-month period from being discharged after an exacerbation of COPD in spite of high levels of psychological distress and reduced QoL.     

Relationships between appetite and quality of life in hemodialysis patients

The aim of this paper was to investigate the association between appetite and kidney-disease specific quality of life in maintenance hemodialysis patients. Quality of life (QoL) was measured using the kidney disease quality of life survey. Appetite was measured using self-reported categories and a visual analog scale. Other nutritional parameters included Patient-Generated Subjective Global Assessment (PGSGA), dietary intake, body mass index and biochemical markers C-reactive protein and albumin. Even in this well nourished sample (n=62) of hemodialysis patients, PGSGA score (r=-0.629), subjective hunger sensations (r=0.420) and body mass index (r=-0.409) were all significantly associated with the physical health domain of QoL. As self-reported appetite declined, QoL was significantly lower in nine domains which were mostly in the SF36 component and covered social functioning and physical domains. Appetite and other nutritional parameters were not as strongly associated with the Mental Health domain and Kidney Disease Component Summary Domains. Nutritional parameters, especially PGSGA score and appetite, appear to be important components of the physical health domain of QoL. As even small reductions in nutritional status were associated with significantly lower QoL scores, monitoring appetite and nutritional status is an important component of care for hemodialysis patients.     

Association between Malnutrition and Quality of Life in Elderly Patients with Rheumatoid Arthritis

Rheumatoid arthritis (RA) is a progressive articular disease. In addition to damaging the joints, it may cause multiple organ complications, and considerably impair the patient’s functioning. Elderly patients with RA report pain, fatigue, mood disorders, sleep disorders and insomnia, accompanied by weakness, poor appetite, and weight loss. All these factors combined have an adverse effect on the patient’s perceived quality of life (QoL). Due to the chronic nature of RA and the high risk of malnutrition in this patient group, the present study investigated QoL, activities of daily living, and frailty syndrome severity in relation to MNA (Mini Nutritional Assessment) questionnaire scores among elderly RA patients. The study included 98 patients (aged over 60) diagnosed with RA per the ARA (American Rheumatism Association) criteria. The following standardized instruments were used: WHOQoL-BREF for QoL, the Edmonton Frail Scale for frailty syndrome severity, MNA for nutritional status assessment, and MMSE (Mini-Mental State Examination) to assess any cognitive impairment. Medical data were obtained from hospital records. Patients with a different nutritional status differed significantly in terms of limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL). Higher levels of malnutrition were associated with greater limitations in activity. An adverse impact of lower body weight on cognitive function was also observed (dementia was identified in 33.33% of malnourished patients vs. 1.79% in patients with a normal body weight). Likewise, frailty was more common in malnourished patients (mild frailty syndrome in 33.3%, moderate in 16.67%, and severe in 16.67%). Malnourished patients had significantly lower QoL scores in all WHOQoL-BREF questionnaire domains than those with a normal body weight, and multiple-factor analysis for the impact of selected variables on QoL in each domain demonstrated that frailty was a significant independent determinant of poorer QoL in all domains: perceived quality of life (β = −0.069), perceived health (β = −0.172), physical domain (β = −0.425), psychological domain (β = −0.432), social domain (β = −0.415), environmental domain (β = −0.317). Malnutrition was a significant independent determinant of QoL in the “perceived health” domain (β = −0.08). In addition, regression analysis demonstrated the positive impact of male sex on QoL scores in the psychological (β = 1.414) and environmental domains (β = 1.123). Malnourished patients have a lower QoL than those with a normal body weight. Malnutrition adversely affects daily functioning, cognitive function, and the severity of frailty syndrome. Frailty syndrome is a significant independent determinant of poorer QoL in all WHOQoL BREF domains.     

Age Categories Differences in Subjective Quality of Life of Women with Physical Disabilities

ObjectiveThe objective of the study was to analyse and compare the subjective quality of life (S-QoL) of women with physical disabilities (PDs) through satisfaction with the quality of life domains and the overall quality of life assessment.MethodsThe sample comprised of women with PDs (n=137), divided into 4 age categories: 19-29 yrs. (n=53); 30-44 yrs. (n=25); 45-59 yrs. (n=24) and over 60 yrs. (n=35). The Subjective Quality of Life Analyses questionnaire and the WHO User Manual were used as a primary research method. The Wilcoxon Signed Rank Test was used to assess the differences between QoLDs, Kruskal Wallis test to assess differences in S-QoL among four independent groups and Mann Whitney U-test between two age categories.ResultsThe highest satisfaction in all age categories of women was found in the social relations domain, and in the 19-29 yr-old women equally in the social relations and physical health domains. The highest dissatisfaction was reported with the psychological health and environment domains. The key finding is that the main differences are between the youngest category (aged 19-29 yrs) and the three older categories with regard to physical health, environment and overall QoL.ConclusionsIt is necessary to continue this line of research with a greater focus on exploring the ways in which the psychological health domain can be improved as an integral part of S-QoL, and to also focus on the QoL indicators that make up the environment domain and search for ways to enhance these.     

Socioeconomic status and quality of life in population‐based Australian men: data from the Geelong Osteoporosis Study

Objective : To investigate the relationship between socioeconomic status (SES) and reported perceptions of quality of life (QOL) in a cross‐sectional population‐based analysis of a representative sample of Australian men. Methods : In 917 randomly recruited men aged 24–92 years, we measured QoL in the domains of physical health, psychological health, environment and social relationships, using the Australian World Health Organization Quality of Life Instrument (WHOQOL‐BREF). Residential addresses were cross‐referenced with Australian Bureau of Statistics 2006 census data to ascertain SES. Participants were categorised into lower, mid, or upper SES based on the Index of Relative Socioeconomic Disadvantage and Advantage (IRSAD), the Index of Economic Resources (IER), and the Index of Education and Occupation (IEO). Lifestyle and health information was self‐reported. Results : Males of lower SES reported poorer satisfaction with physical health (OR=0.6, 95%CI 0.4–0.9, p=0.02), psychological health (OR=0.4, 95%CI 0.3–0.7, p<0.001) and environment (OR=0.5, 95%CI 0.3–0.7, p<0.001), although not social relationships (p=0.59). The poorest QOL for each domain was observed in the lower and upper SES groups, representing an inverse U‐shaped pattern of association; however, statistical significance was only observed for psychological health (OR=0.5, 95%CI 0.4–0.7, p<0.001). These relationships were similar for IEO and IER. Conclusions : Men from lower and upper SES groups have lower QOL compared to their counterparts in the mid SES group.     

The effect of menopause on grip and pinch strength: results from the Chicago, Illinois, site of the Study of Women's Health Across the Nation

Women may experience a decline in physical function during menopause. Whether this decline is due to aging or to changes in hormonal status is unknown. The authors performed a longitudinal data analysis on data collected between 1996 and 2001 to determine the effects of menopausal status, age, race, and use of hormone replacement therapy (HRT) on 3-year changes in grip and pinch strength. Participants were 563 women from the Chicago, Illinois, site of the Study of Women's Health Across the Nation. According to adjusted analyses, women who became postmenopausal showed a 1.04-kg decline in grip strength (p = 0.10) and a 0.57-kg decline in pinch strength (p = 0.002) relative to women who remained premenopausal. Women who became early perimenopausal showed a 0.20-kg decline in pinch strength (p = 0.04), whereas women who transitioned to late perimenopause showed a 0.93-kg decline in grip strength (p = 0.07). Effects of menopausal status on grip and pinch strength did not vary by race. A significant HRT-by-race interaction for grip strength was found; African-American HRT users had greater grip strength during the study, whereas Caucasian HRT users did not (p = 0.05). Greater physical activity was the strongest predictor of grip and pinch strength (p < 0.0001). Results indicate that transition through menopause is associated with a decline in grip and pinch strength.     

Quality of life of men with AIDS and the model of social determinants of health

OBJECTIVE:

to analyze the quality of life (QoL) of men with AIDS from the perspective of the model of social determinants of health (MSDH).

METHOD:

cross-sectional study conducted in an outpatient infectious diseases clinic from a Brazilian university hospital over the course of one year with a sample of 138 patients. A form based on the MSDH was used to collect sociodemographic data addressing individual, proximal, intermediate determinants and the influence of social networks together with an instrument used to assess the QoL of people with HIV/AIDS. The project was approved by the Institutional Review Board (Protocol No. 040.06.12).

RESULTS:

according to MSDH, most men with AIDS were between 30 and 49 years old (68.1%), mixed race (59.4%), heterosexual (46.4%), single (64.5%), Catholic (68.8%), had a bachelor''s degree (39.2%), had no children (61.6%), and had a formal job (71.0%). The perception of QoL in the physical, level of independence, environment, and spirituality domains was intermediate, while QoL was perceived to be superior in the domains of psychological and social relationship. A perception of lower QoL was presented by homosexual (p=0.037) and married men (p=0.077), and those with income below one times the minimum wage (p=0.042). A perception of greater QoL was presented by those without a religion (p=0.005), living with a partner (p=0.049), and those who had a formal job (p=0.045).

CONCLUSION:

social determinants influence the QoL of men with AIDS.     

The competing effects of disease states on quality of life of the elderly:

During the period 1993–1994 we conducted a study in Israel on a national-based sample of 960 men to examine the relationships between urinary symptoms and various domains of quality of life (QoL). Regression analyses were performed for each of the eight SF-36 domains, separately for the entire population and for those without any co-morbidity. The dependent variable was the SF-36 domain scores. The independent variables included age, origin, education, employment and economic status, the degree of disturbance caused by urinary symptoms and the existence of co-morbidities. There was a significant difference between the entire population and the population without co-morbidities. In the entire population we found that severely bothersome urinary symptoms were related to scores on three QoL domains (social function, role–emotional and mental health) but there was no association with physical functioning and general health perceptions. In men without co-morbidity, urinary symptoms were substantially related to physical functioning and general health perceptions. These findings indicate that the relative weight of the impact of a symptom or disease on QoL domains is changed by the presence of other competing factors, such as co-morbidities or sociodemographic attributes.     

Design of an Individualised Measure of the Impact of Macular Disease on Quality of Life (the MacDQoL)

The aim of this study was to design an individualised questionnaire to measure the impact of macular disease (MD) on quality of life (QoL). Principles underlying the Schedule for the Evaluation of Individual Quality of Life (SEIQoL) interview method and the Audit of Diabetes-Dependent Quality of Life (ADDQoL) diabetes-specific questionnaire influenced the Macular Disease-Dependent Quality of Life (MacDQoL) design. The MacDQoL specifies domains of QoL that were selected using focus group methodology and refined following a postal pilot study of members of the UK Macular Disease Society (MDS). Respondents rated the impact of MD on each domain and the importance of each domain to their QoL. Mean domain scores from 69 respondents indicated that MD had a negative impact on all the domains of QoL investigated in the measure. There was preliminary evidence of good internal consistency reliability (Cronbach's alpha = 0.93, n = 37). Respondents who were registered partially sighted (P/S) or blind reported poorer QoL than those who were not registered (Kruskal-Wallis: chi2 = 14.03, n = 62, p < 0.001). This evidence suggests that the measure will be sensitive to subgroup differences. The instrument has been further refined following the pilot study. The MacDQoL is being used in clinical trials and psychometric evaluation of the measure will be carried out using trial data. The measure is available for clinical use and has been linguistically validated in 15 other languages.     

A national study of the importance of oral health to life quality to inform scales of oral health related quality of life

OBJECTIVES: To assess the content validity of traditional oral health status scales as measures of oral health related quality of life (OHQOL), based on a general public's perception of the most important ways in which oral health affects quality of life (QoL). METHODS: A nationwide United Kingdom study involving a random probability sample of 1778 adults. Data were collected by face-to-face interviews in participants homes. RESULTS: Most 75% (1332) perceived oral health as being important to QoL. Among them, 53% (699/1332) identified oral health's importance to QoL as being in a positive manner. Existing scales predominantly fail to include this dimension. The general public ranked oral health's importance to QoL through a range of physical, social and psychological domains. Most frequently though affecting eating or comfort; domains considered by all instruments. Other domains/ways are presented. It is apparent that even when some of the multidomain scales are employed, they frequently omit items that the public perceives as being most important to QoL. CONCLUSION: The study raises concerns about the appropriateness of utilising many of the existing oral health status scales as measures of OHQOL because the concepts do not appear to be interchangeable.     

Perception of quality of life by patients, partners and treating physicians

The objective of the study was to determine possible differences in perception of quality of life (QoL) between patients with metastatic breast or prostate cancer, their partners, and the treating physician. Patients with metastatic breast cancer (n = 71), and metastatic prostate cancer (n = 29), a partner, and the physician each completed the same QoL questionnaire indicating how they perceived the patient's QoL. The European organization for research and treatment of cancer (EORTC) QLQ-C30 questionnaire was used to assess patients with breast cancer and the modified prostate cancer specific quality of life instrument (PROSQOLI) for patients with prostate cancer. There was reasonable agreement in mean scores between patients, and physicians or partners, for many domains of QoL; however, there was substantial discordance between scores when considering individual patients. For patients with metastatic breast cancer, physicians systematically underestimated overall QoL (p = 0.0002), social functioning (p = 0.001), and role functioning (p = 0.008), while partners showed better agreement. With prostate cancer physicians tended to underestimate pain, while mean scores for spouses were more concordant. There is substantial variability between ratings of QoL by physicians or partners, as compared to patient ratings. Medical decisions should be based on information about QoL provided by patients using validated methods. This revised version was published online in July 2006 with corrections to the Cover Date.     

Personal goals and factors related to QoL in Dutch homeless people: what is the role of goal‐related self‐efficacy?

Very little is known about the personal goals of homeless people and how these relate to their quality of life (QoL). By using survey data on 407 homeless adults upon entry to the social relief system in 2011, we examined the personal goals of homeless adults and the association between their perceived goal‐related self‐efficacy and their QoL. A hierarchical regression analysis was used to analyse the association between QoL and goal‐related self‐efficacy, relative to factors contributing to QoL, such as demographic characteristics, socioeconomic resources, health and service use. Results indicate that the majority of homeless adults had at least one personal goal for the coming 6 months and that most goals concerned housing and daily life (94.3%) and finances (83.6%). The QoL of homeless adults appeared to be lower in comparison with general population samples. General goal‐related self‐efficacy was positively related to QoL (β = 0.09, P = 0.042), independent of socioeconomic resources (i.e. income and housing), health and service use. The strongest predictors of QoL were psychological distress (β = ?0.45, P < 0.001), income (β = 0.14, P = 0.002) and being institutionalised (β = 0.12, P = 0.004). In conclusion, the majority of homeless adults entering the social relief system have personal goals regarding socioeconomic resources and their goal‐related self‐efficacy is positively related to QoL. It is therefore important to take the personal goals of homeless people as the starting point of integrated service programmes and to promote their goal‐related self‐efficacy by strength‐based interventions.     

Drinking patterns, psychological distress and quality of life in a Norwegian general population-based sample

Background

The purpose of this study was to investigate possible relationships between drinking patterns, psychological distress and quality of life (QoL) in a general population-based sample in Norway.

Methods

A random sample of 4,000 Norwegian citizens, aged 18 to 79, was drawn from the National Register held by Statistics Norway.

Results

Males consumed significantly more alcohol and reported more drinking-related problems with more negative consequences, compared to females. Psychological distress increased, and all QoL domain scores decreased with increasing alcohol consumption within the group drinking alcohol at all. The excessive drinkers demonstrated the highest level of psychological distress and lowest QoL in the psychological, social relationships and environment domains. Non-drinkers reported to have poorest QoL in the physical health domain, whereas light and moderate drinkers demonstrated lowest psychological distress and best QoL. Psychological distress demonstrated substantial more importance for QoL than socio-demographic variables, alcohol consumption, alcohol dependency and negative consequences of alcohol use did.

Conclusion

The findings indicate the need for a focus on psychological distress and its negative impact upon all QoL domains. Attention should also be paid to excessive drinkers who have poor QoL (psychological, social relationships and environment domains) and a high level of psychological distress. In addition, non-drinkers reported poor physical health. Further research is needed concerning the relation between alcohol consumption, psychological distress and QoL both in general population studies and in more specific samples.     

Quality of life among dentists of a local public health service

OBJECTIVE: To assess quality of life and related factors among dentists of a local public health service. METHODS: A cross-sectional study was carried out comprising dentists working (N=237) in the city of Goiania, Midwesthern Brazil, in 2004. Data were collected using a questionnaire including the WHOQOL-Bref instrument, demographic data and occupation information, and self-rated health status and quality of life. Simple and multiple logistic regression analyses were used to estimate associations. RESULTS: Response rate was 62.9% (N=149). The physical domain had the highest mean scores (70.3; SD=14.6) and the environment domain had the lowest mean scores (59.4; SD=13.7). Most dentists had low quality of life in the physical (51.0%) and psychological domains (52.3%) and high quality of life in the social relationships (50.3%) and environment domains (59.1%). The multiple logistic regression showed an association between self-rated health status and satisfaction and the physical domain; and self-rated quality of life and the physical, psychological and environment domains. CONCLUSIONS: The occupation group studied showed low quality of life in the physical and psychological domains and high quality of life in the social relationships and environment domains, which were associated to self-rated quality of life, current health status and satisfaction.     

Relationship between Nutritional Status and Clinical Outcome in Patients Treated for Lung Cancer

Background. Between 34.5% and 69% of the patients with lung cancer are at risk of malnutrition. Quality of life (QoL) and physical status assessment provides valuable prognostic data on lung cancer patients. Malnutrition is a prognostic parameter for clinical outcome. Therefore, the identification of significant factors affecting the clinical outcome and QoL is important. The purpose of this study was to evaluate the relationship between nutritional status and outcome, i.e., overall survival, time to tumor progression, and QoL, in lung cancer patients. Materials and methods. We performed a systematic search of the Pubmed/MEDLINE databases per the Cochrane guidelines to conduct a meta-analysis consistent with the PRISMA statement, using the following keywords: “lung cancer,” “malnutrition,” “nutrition,” “quality of life,” “well-being,” “health-related quality of life,” and “outcome.” Out of the 96 papers identified, 12 were included in our meta-analysis. Results. Our meta-analysis shows that patients with a good nutritional status have a better QoL than malnourished patients in the following functioning domains: physical (g = 1.22, 95% CI = 1.19 to 1.46, p < 0.001), role (g = 1.45, 95% CI = 1.31 to 1.59, p < 0.001), emotional (g = 1.10, 95% CI = 0.97 to 1.24, p < 0.001), cognitive (g = 0.91, 95% CI = 0.76 to 1.06, p < 0.001), and social (g = 1.41, 95% CI = 1.27 to 1.56, p < 0.001). The risk of death was significantly higher in malnourished than in well-nourished patients (HR = 1.53, 95% CI = 1.25 to 1.86, p < 0.001). Nutritional status was significantly associated with survival, indicating that patients with a poorer nutritional status are at more risk of relapse. Conclusions. Nutritional status is a significant clinical and prognostic parameter in the assessment of lung cancer treatment. Malnutrition is associated with poorer outcome in terms of overall survival, time to tumor progression, and QoL in patients treated for lung cancer.     

Quality of life and burnout among public high school and primary school teachers in Southern Brazil

In order to investigate quality of life among public schoolteachers in relation to socio-demographic characteristics and work conditions, a cross-sectional study was conducted in a sample of 601 primary and secondary teachers from the State and Municipal public school system in the urban area of Pelotas, Rio Grande do Sul State, Brazil. The study analyzed the following domains from the WHOQOL-BREF scale: physical health, psychological health, social relationships, and environment. The mean indices were: 69.2 (SD = 16.8) for physical health, 70.6 (SD = 14.0) for psychological health, 72.5 (SD = 17.3) for social relationships, and 60.7 (SD = 14.0) for environment. Age, time in the teaching career, and total number of students were not significantly associated with quality of life. Teachers in municipal schools scored higher than their counterparts in the State public schools in the physical health domain (p = 0.026). Men scored higher than women in the physical and psychological health domains. Higher family income was associated with better quality of life. Higher classroom workload was associated with better scores in the physical health and environment domains.
