Responsiveness of the anxiety/depression dimension of the 3- and 5-level versions of the EQ-5D in assessing mental health

Anxiety and depression among adults with haemophilia A: Patient and physician reported symptoms from the real-world European CHESS II study

INTRODUCTION

The physical pain and disability affecting many people with haemophilia A (PwHA) are known detractors from psychological wellbeing. While psychosocial support is considered a core tenet of the haemophilia comprehensive care structure, the extent to which mental health challenges are detected and monitored by the individuals treating haematologist remains relatively unexplored.

AIM

To describe prevalence of anxiety and depression in a real-world cohort of adult PwHA and evaluate the congruence in reporting of anxiety or depression (A/D) between PwHA and their treating physicians.

METHODS

Data for PwHA without inhibitors was drawn from the European 'Cost of Haemophilia: A Socioeconomic Survey II' (CHESS II) study. Haematologist-indicated comorbidities of anxiety and depression were unified into a single A/D indicator. The EQ-5D-5L health status measure was used to characterise self-reported A/D, with individuals stratified into two non-mutually exclusive subgroups based on level of A/D reported (Subgroup A: 'some' or above; Subgroup B: 'moderate' or above).

RESULT

Of 381 PwHA with evaluable EQ-5D-5L responses, 54% (n = 206) self-reported at least some A/D (Subgroup A) and 17% (n = 66) reported at least moderate A/D (Subgroup B). Patient-physician congruence in A/D reporting was 53% and 76% for Subgroups A and B, respectively. Descriptive analysis suggested that individuals with physician- and/or self-reported A/D experienced worse clinical outcomes (bleeding events, joint disease, chronic pain).

CONCLUSION

While adverse clinical outcomes appear to correlate with A/D, self-reports of moderate-severe symptoms occasionally lacked formal recognition from treating physicians. Cross-disciplinary surveillance of mental health issues could improve both psychological and clinical outcomes among PwHA.

Assessing the validity and responsiveness of a generic preference quality of life measure in the context of posttraumatic stress disorder

PURPOSE

There is limited research exploring the usefulness of generic preference-based quality of life (GPQoL) measures used to facilitate economic evaluation in the context of posttraumatic stress disorder (PTSD). The aim of the current study was to explore the validity and responsiveness of a common GPQoL measure (Assessment of Quality of Life 8 Dimension [AQoL-8D]) in relation to a PTSD condition-specific outcome measure (Posttraumatic Stress Disorder Checklist for the DSM-5 [PCL-5]).

METHOD

This aim was investigated in a sample of individuals (N = 147) who received trauma-focused cognitive-behavioural therapies for posttraumatic stress disorder. Convergent validity was investigated using spearman's correlations, and the level of agreement was investigated using Bland-Altman plots. Responsiveness was investigated by exploring the standardised response means (SRM) from pre-post-treatment across the two measures, which allow the comparison of the magnitude of change between the measures over time.

RESULTS

Correlations between the AQoL-8D (dimensions, utility and summary total scores) and the PCL-5 total score ranged from small to large and agreement between the measures was considered moderate to good. While SRMs were large for the AQoL-8D and PCL-5 total scores, the SRM for the PCL-5 was nearly double that of the AQoL-8D.

CONCLUSION

Our findings demonstrate that the AQoL-8D has good construct validity but present preliminary evidence that economic evaluations using only GPQoL measures may not fully capture the effectiveness of PTSD treatments.

Responsiveness to change in health status of the EQ-5D in patients treated for depression and anxiety

BACKGROUND

The EQ-5D is a commonly used generic measure of health but evidence on its responsiveness to change in mental health is limited. This study aimed to explore the responsiveness of the five-level version of the instrument, the EQ-5D-5 L, in patients receiving treatment for depression and anxiety.

METHODS

Patient data (N = 416) were collected at baseline and at end of treatment in an observational study in a Norwegian outpatient clinic. Patients were adults of working age (18-69 years) and received protocol-based metacognitive or cognitive therapy for depression or anxiety according to diagnosis. Responsiveness in the EQ-5D was compared to change in the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory (BAI). Effect sizes (Cohen's d), Standardised response mean (SRM), and Pearson's correlation were calculated. Patients were classified as "Recovered", "Improved", or "Unchanged" during treatment using the BDI-II and the BAI. ROC analyses determined whether the EQ-5D could correctly classify patient outcomes.

RESULTS

Effect sizes were large for the BAI, the BDI-II, the EQ-5D value and the EQ VAS, ranging from d = 1.07 to d = 1.84. SRM were also large (0.93-1.67). Pearson's correlation showed strong agreement between change scores of the EQ-5D value and the BDI-II (r_s -0.54) and moderate between the EQ-5D value and the BAI (r_s -0.43). The EQ-5D consistently identified "Recovered" patients versus "Improved" or "Unchanged" in the ROC analyses with AUROC ranging from 0.72 to 0.84.

CONCLUSION

The EQ-5D showed good agreement with self-reported symptom change in depression and anxiety, and correctly identified recovered patients. These findings indicate that the EQ-5D may be appropriately responsive to change in patients with depression and anxiety disorders, although replication in other clinical samples is needed.

Reliability and validity of using EQ-5D-5L among healthy and adolescents with major mental health disorders in Ethiopia

BACKGROUND

The EQ-5D is a validated and widely used generic measure of health-related quality of life (HRQoL) in both healthy individuals and those with various medical conditions. The objective of this study was to test whether EQ-5D-5L is reliable and valid for use among school sample adolescents and those with major mental health disorders in Ethiopia.

METHODS

Participants were recruited from ten sub-districts comprising the Butajira Rural Health Programme (BRHP) and Butajira major mental health disorders center. Data were collected using an Amharic (Ethiopia) EQ-5D-5L self-complete-paper and the questionnaire was administered 10 days after the first completion for test-retest procedures. Two-way mixed-effects models absolute intraclass correlation coefficient (ICC) was used to test reliability of the instrument while Kruskal-Wallis rank test with pairwise comparison was used to assess the known group validity of the instrument.

RESULTS

There were 501 (201 school sample and 300 adolescents with major mental health disorders) participants recruited and 497 were included in the sample for analysis. The ICC was high (ICC > 0.7, p < 0.001) for all EQ-5D-5L dimensions, EQ-5D-5L utility index and EQ-VAS scores. The findings revealed that the Amharic EQ-5D-5L has significant known group validity as shown by the difference in scores among various disease group (depression, schizophrenia, and bipolar) and experience of chronic illness.

CONCLUSIONS

The results shows that the Amharic EQ-5D-5L is reliable and valid instrument for the measurement of HRQoL among adolescent populations in Ethiopia.

Anxiety, Depression, and Quality of Life After Procedural Intervention for Uterine Fibroids

Background: Quality of life (QOL) and psychological health has been reported to be decreased among women with gynecological conditions such as uterine fibroids (UFs). Materials and Methods: Women enrolled in the Comparing Options for Management: PAtient-centered REsults for Uterine Fibroids (COMPARE-UF) registry, receiving procedural therapy for symptomatic UFs, were eligible for this analysis if they completed a series of health-related QOL surveys administered at three time points (baseline, 6-12 weeks postprocedure, and 1 year postprocedure; n = 1486). Ethical approval for this study was obtained at each recruiting site and the coordinating center (NCT02260752, clinicaltrials.gov). Results: More than 26% (n = 393) of women reported moderate anxiety/depression on the baseline anxiety/depression domain of the Euro-QOL 5-dimension instrument. At both the 6-12 weeks and 1-year postprocedural follow-up, there was significant improvement in the UF QOL symptom severity score (p < 0.001, p < 0.001), the total UF symptom QOL score (p < 0.001, p < 0.001), and the Euro-QOL 5-dimension visual analog scale (p < 0.001, p = 0.004) compared with the preprocedural baseline scores. The reporting of anxiety/depression decreased by 66.4% among women who were at baseline, whereas 5.6% of women previously reporting no anxiety/depression reported anxiety/depression at the 1-year follow-up. Conclusion: UF symptoms were more severe among women reporting anxiety/depression at baseline. At the 1-year follow-up, health-related QOL scores improved among all women and the prevalence of anxiety/depression decreased in most, but not all women, whereas severity of anxiety/depression worsened in a small percentage of women (5.6%). Overall, these results suggest that UF treatment improves symptoms of anxiety/depression associated with symptomatic UFs.

Patient-Reported Anxiety/Depression After Endovascular Thrombectomy: A post-hoc Analysis of Direct-MT Trial

Objective

To analyze the effect of endovascular thrombectomy (EVT) alone vs. EVT after an intravenous (IV) alteplase of ischemic stroke on a patient-reported anxiety/depression, and to identify predictors of patient-reported anxiety/depression by analyzing data from Direct Intraarterial Thrombectomy in Order to Revascularize the patients with Acute Ischemic Stroke with a Large Vessel Occlusion Efficiently in Chinese Tertiary Hospitals: a Multicenter Randomized Clinical Trial (DIRECT-MT).

Methods

Patients with acute ischemic stroke (AIS), triggered by a large-vessel occlusion in the anterior circulation, were randomly allocated to undergo an EVT after IV alteplase (combination-therapy group) or an EVT alone (EVT-alone group) at a 1:1 ratio in DIRECT-MT. Patients in both groups were followed up for 90 days (±14 days) after stroke using a structured modified Ranking Scale (mRS), a Barthel Index (BI), and a 5-Dimensional European Quality of Life Scale (EQ-5D-5L). Patients who returned EQ-5D-5L were included. The EQ-5D-5L anxiety/depression dimension was used to analyze the patient-reported anxiety/depression. First, differences in patient-reported anxiety/depression were compared between the combination-therapy group and the EVT-alone group. Then, the baseline and influencing factors between the anxiety/depression group and no anxiety/depression group were analyzed using univariate regression analysis. Finally, variables with p < 0.1 in univariate regression were subjected to multivariable binary regression analysis to screen independent predictors for patient-reported anxiety /depression after ischemic stroke.

Results

: Five hundred fifteen patients returned the EQ-5D-5L in Direct-MT. Of these patients, 226 (43.88%) reported a level of anxiety/depression, and about 7% reported a severe or extremely severe anxiety/depression. The patient-reported anxiety/depression in the EVT-alone group was significantly higher than that in the combination-therapy group (48.26% vs. 39.45%, p = 0.04). The clinical outcomes were significantly different between the no Anxiety/Depression Group and the anxiety/depression group (mRS at 90 days:2 vs 3, p < 0.001; BI of 95 or 100 at 90 days: 73.36% vs 42.04%, p < 0.001; EQ-5D-5l utility indexes at 90 days:0.96 vs.57, p < 0.001). Logistic regression analysis showed that allocation to thrombolysis before EVT strategy was inversely associated with anxiety/depression [0.61(0.40, 0.94), p = 0.03], an insular cortex ischemia, and National Institute of Health Strocke Scale (NIHSS) at 7 days were positively associated with anxiety/depression [2.04(1.07, 3.90), p = 0.03; 1.07(1.03, 1.12), p < 0.001].

Conclusions

Patient-reported anxiety/depression may suggest that there is a benefit to administering intravenous alteplase before EVT. It may also indicate that it is better to provide IV alteplase before EVT, rather than EVT alone according to patient-reported anxiety/depression. Future research should consider not only the motor function impairments but also the patient-reported mental problems as measures of treatment efficacy in patients with stroke (DIRECT-MT ClinicalTrials.gov number, NCT03469206).

Cost-effectiveness analyses of augmented cognitive behavioral therapy for pharmacotherapy-resistant depression at secondary mental health care settings

AIM

Pharmacotherapy is the primary treatment strategy in major depression. However, two-thirds of patients remain depressed after the initial antidepressant treatment. Augmented cognitive behavioral therapy (CBT) for pharmacotherapy-resistant depression in primary mental health care settings proved effective and cost-effective. Although we reported the clinical effectiveness of augmented CBT in secondary mental health care, its cost-effectiveness has not been evaluated. Therefore, we aimed to compare the cost-effectiveness of augmented CBT adjunctive to treatment as usual (TAU) and TAU alone for pharmacotherapy-resistant depression at secondary mental health care settings.

METHODS

We performed a cost-effectiveness analysis at 64 weeks, alongside a randomized controlled trial involving 80 patients who sought depression treatment at a university hospital and psychiatric hospital (one each). The cost-effectiveness was assessed by the incremental cost-effectiveness ratio (ICER) that compared the difference in costs and quality-adjusted life years, and other clinical scales, between the groups.

RESULTS

The ICERs were JPY -15 278 322 and 2 026 865 for pharmacotherapy-resistant depression for all samples and those with moderate/severe symptoms at baseline, respectively. The acceptability curve demonstrates a 0.221 and 0.701 probability of the augmented CBT being cost-effective for all samples and moderate/severe depression, respectively, at the threshold of JPY 4.57 million (GBP 30 000). The sensitivity analysis supported the robustness of our results restricting for moderate/severe depression.

CONCLUSION

Augmented CBT for pharmacotherapy-resistant depression is not cost-effective for all samples including mild depression. In contrast, it appeared to be cost-effective for the patients currently manifesting moderate/severe symptoms under secondary mental health care.

Psychometric assessment of EQ-5D-5L and ReQoL measures in patients with anxiety and depression: construct validity and responsiveness

PURPOSE

Generic health measures have been questioned for quantifying mental-health-related outcomes. In patients with anxiety and/or depression, our aim is to assess the psychometric properties of the preference-based EQ-5D-5L (generic health) and ReQoL-UI (recovery-focussed quality of life) for economic evaluation against the PHQ-9 (depression) and GAD-7 (anxiety). EQ-5D-5L anxiety/depression item and ReQoL-10 are also assessed.

METHODS

A 2:1 (intervention: control) randomised controlled trial collected measures at baseline and 8 weeks post baseline; in the intervention arm, data were also collected 3, 6, 9, and 12-months post baseline. EQ-5D-5L preference-based scores were obtained from the value set for England (VSE) and 'cross-walked' EQ-5D-3L United Kingdom (UK) value set scores. ReQoL-UI preference-based scores were obtained from its UK value set as applied to seven ReQoL-10 items. EQ-5D-5L and ReQoL measures' construct validity and responsiveness were assessed compared against PHQ-9 and GAD-7 scores and group cut-offs.

RESULTS

361 people were randomised to intervention (241) or control (120). ReQoL-UI/-10 had better construct validity with depression severity than the EQ-5D-5L (VSE/cross-walk scores), which had relatively better construct validity with anxiety severity than the ReQoL-UI/-10. Across all intervention-arm time-points relative to baseline, responsiveness was generally better for EQ-5D-5L (VSE in particular) than ReQoL-UI, but worse than ReQoL-10.

CONCLUSION

There is insufficient evidence to recommend the ReQoL-UI over EQ-5D-5L for economic evaluations to capture anxiety severity. However, there may be rationale for recommending the ReQoL-UI over the EQ-5D-5L to capture depression severity given its better construct validity, albeit poorer responsiveness, and if recovery-focussed quality of life relative to condition-specific symptomology is the construct of interest.

A systematic review of fear of cancer recurrence related healthcare use and intervention cost-effectiveness

OBJECTIVE

Fear of cancer recurrence (FCR) is a common and burdensome psychological condition affecting cancer survivors. This systematic review aims to synthesise current evidence regarding: (1) FCR-related healthcare usage and costs and (2) the cost-effectiveness of FCR treatments.

METHODS

We searched MEDLINE, CINAHL, Cochrane and other electronic databases using MeSH headings and keywords for cancer, FCR and costs from their inception to September 2019. Identified studies were screened for eligibility. Original, peer-reviewed journal articles reporting quantitative data from samples of adults treated for cancer written in English were included. Quality was appraised using the Drummond checklist for economic evaluations or the relevant Joanna Briggs Institute Critical Appraisal Tool.

RESULTS

Data from 11 studies were extracted and synthesised. Seven studies addressed the costs of FCR and suggested an increase in the use of primary and secondary healthcare. Four studies addressed the cost-effectiveness of different FCR treatments and suggest that some treatments may cost-effectively reduce FCR and improve quality of life. Reviewed treatments had an incremental cost-effectiveness ratio between AU$3,233 and AU$152,050 per quality-adjusted life year gained when adjusted to 2019 Australian dollars. All studies were of sufficient quality to be synthesised in this review.

CONCLUSIONS

FCR appears to be associated with greater use of certain healthcare resources, and FCR may be treated cost-effectively. Thus, appropriate FCR treatments may not only reduce the individual burden, but also the strain on the healthcare system. Further high-quality research is needed to confirm this and ensure the future implementation of efficient and sustainable FCR treatments.

Health-related quality of life in different trimesters during pregnancy

Background

Pregnant women experience physical, physiological, and mental changes. Health-related quality of life (HRQoL) is a relevant indicator of psychological and physical behaviours, changing over the course of pregnancy. This study aims to assess HRQoL of pregnant women during different stages of pregnancy.

Methods

This cross-sectional study was performed using the The EuroQoL Group’s five-dimension five-level questionnaire (EQ-5D-5L) to assess the HRQoL of pregnant women, and demographic data were collected. This study was conducted in a regional university hospital in Guangzhou, China.

Results

A total of 908 pregnant women were included in this study. Pregnant women in the early 2^nd trimester had the highest HRQoL. The HRQoL of pregnant women rose from the 1st trimester to the early 2nd trimester, and dropped to the bottom at the late 3rd trimester due to some physical and mental changes. Reports of pain/discomfort problem were the most common (46.0%) while self-care were the least concern. More than 10% of pregnant women in the 1st trimester had health-related problems in at least one dimension of whole five dimensions. In the whole sample, the EuroQoL Group’s visual analog scale (EQ-VAS) was 87.86 ± 9.16. Across the gestational stages, the HRQoL remained stable during the pregnancy but the highest value was observed in the 1st trimester (89.65 ± 10.13) while the lowest was in the late 3rd trimester (87.28 ± 9.13).

Conclusions

During pregnancy, HRQoL were associated with gestational trimesters in a certain degree. HRQoL was the highest in the early 2nd trimester and then decreased to the lowest in the late 3rd trimester due to a series of physical and psychological changes. Therefore, obstetric doctors and medical institutions should give more attention and care to pregnant women in the late 3rd trimester.

Application of the EQ-5D in the Middle East: A Systematic Review Focusing on Patients Living in the Kingdom of Saudi Arabia

Patients’ quality of life (QoL) and reported outcomes are critical indicators of the burden of a disease and the benefits of healthcare intervention. This systematic review explores publications that have adapted the EQ-5D for use with a population living in Saudi Arabia. The review of the following databases: MEDLINE, EMBASE, Wiley’s Database, EBSCO, and ClinicalTrials.gov was conducted on December 1, 2020. The search strategy was adapted from the SPIDER search tool, and the included articles were classified by author, year of publication, region, disease of interest, sample size, type of EQ-5D, and format. Level of EQ-5D was classified as either 3L or 5L. Thirteen articles met the search inclusion criteria. The earliest publication was conducted in 2015 and the latest in 2020. These studies were conducted in four Saudi administrative regions, and multiple conditions or treatments were studied, the most studied condition being diabetes mellitus, followed by musculoskeletal disorders, back pain, and injuries. This systematic review article finds that the EQ-5D has been well adapted in the KSA. However, continued work is needed to investigate the quality of life for major conditions such as cardiovascular disease and cancer. Moreover, QoL research is lacking in certain regions, such as southern and northern Saudi Arabia. Despite the successful application and validation of the EQ-5D, a local QoL tool is needed to capture the unique context of patients within the healthcare system in the Middle East.

Quality of life under the COVID-19 quarantine

BACKGROUND

COVID-19 has spread rapidly throughout the world, causing thousands of illnesses and deaths. To fight this pandemic, almost all governments and health authorities have focused on prevention. In March or April, most countries' officials imposed home quarantine and lockdown measures nationwide.

PURPOSE

This study sought to assess health-related quality of life (HRQoL) and anxiety levels among people in Portugal under mandatory home quarantine due to the COVID-19 pandemic. The results were compared to the general Portuguese population's HRQoL before the COVID-19 outbreak. This research also aimed to understand the factors that can influence the respondents' HRQoL.

METHODS

A sample of Portugal's population quarantined at home (n = 904) filled in an online survey comprising the Generalized Anxiety Disorder 7-item and the EQ-5D-5L and other questions about sociodemographic characteristics, feelings, duties and activities during the quarantine. The sample was weighted to mirror the general population's gender, age and education. Descriptive analyses and correlation coefficients were used to evaluation the respondents' anxiety and HRQoL. Generalised linear models were estimated to identify determinants of HRQoL during the COVID-19 quarantine.

RESULTS

The results show that individuals quarantined at home reported higher anxiety and lower HRQoL levels and that people with more anxiety tended to have a lower HRQoL. Females and elderly individuals experienced the highest levels of anxiety and poorest HRQoL. In addition, HRQoL during the quarantine can be explained by various occupational and attitudinal variables, as well as sociodemographic variables.

CONCLUSION

Individuals' mental health should be taken into consideration during pandemics or other emergency situations. Anxiety and other factors can decrease people's HRQoL, in conjunction with the pandemic's social and economic consequences.

Psychometric properties of the EQ-5D-5L: a systematic review of the literature

PURPOSE

Although the EQ-5D has a long history of use in a wide range of populations, the newer five-level version (EQ-5D-5L) has not yet had such extensive experience. This systematic review summarizes the available published scientific evidence on the psychometric properties of the EQ-5D-5L.

METHODS

Pre-determined key words and exclusion criteria were used to systematically search publications from 2011 to 2019. Information on study characteristics and psychometric properties were extracted: specifically, EQ-5D-5L distribution (including ceiling and floor), missing values, reliability (test-retest), validity (convergent, known-groups, discriminate) and responsiveness (distribution, anchor-based). EQ-5D-5L index value means, ceiling and correlation coefficients (convergent validity) were pooled across the studies using random-effects models.

RESULTS

Of the 889 identified publications, 99 were included for review, representing 32 countries. Musculoskeletal/orthopedic problems and cancer (n = 8 each) were most often studied. Most papers found missing values (17 of 17 papers) and floor effects (43 of 48 papers) to be unproblematic. While the index was found to be reliable (9 of 9 papers), individual dimensions exhibited instability over time. Index values and dimensions demonstrated moderate to strong correlations with global health measures, other multi-attribute utility instruments, physical/functional health, pain, activities of daily living, and clinical/biological measures. The instrument was not correlated with life satisfaction and cognition/communication measures. Responsiveness was addressed by 15 studies, finding moderate effect sizes when confined to studied subgroups with improvements in health.

CONCLUSIONS

The EQ-5D-5L exhibits excellent psychometric properties across a broad range of populations, conditions and settings. Rigorous exploration of its responsiveness is needed.

Cost-effectiveness of guideline-based stepped and collaborative care versus treatment as usual for patients with depression - a cluster-randomized trial

BACKGROUND

Depression is associated with major patient burden. Its treatment requires complex and collaborative approaches. A stepped care model based on the German National Clinical Practice Guideline "Unipolar Depression" has been shown to be effective. In this study we assess the cost-effectiveness of this guideline based stepped care model versus treatment as usual in depression.

METHODS

This prospective cluster-randomized controlled trial included 737 depressive adult patients. Primary care practices were randomized to an intervention (IG) or a control group (CG). The intervention consisted of a four-level stepped care model. The CG received treatment as usual. A cost-utility analysis from the societal perspective with a time horizon of 12 months was performed. We used quality-adjusted life years (QALY) based on the EQ-5D-3L as effect measure. Resource utilization was assessed by patient questionnaires. Missing values were imputed by 'multiple imputation using chained equations' based on predictive mean matching. We calculated adjusted group differences in costs and effects as well as incremental cost-effectiveness ratios. To describe the statistical and decision uncertainty cost-effectiveness acceptability curves were constructed based on net-benefit regressions with bootstrapped standard errors (1000 replications). The complete sample and subgroups based on depression severity were considered.

RESULTS

We found no statically significant differences in costs and effects between IG and CG. The incremental total societal costs (+€5016; 95%-CI: [-€259;€10,290) and effects (+ 0.008 QALY; 95%-CI: [- 0.030; 0.046]) were higher in the IG in comparison to the CG. Significantly higher costs were found in the IG for outpatient physician services and psychiatrist services in comparison to the CG. Significantly higher total costs and productivity losses in the IG in comparison to the CG were found in the group with severe depression. Incremental cost-effectiveness ratios for the IG in comparison to the CG were unfavourable (complete sample: €627.000/QALY gained; mild depression: dominated; moderately severe depression: €645.154/QALY gained; severe depression: €2082,714/QALY gained) and the probability of cost-effectiveness of the intervention was low, except for the group with moderate depression (ICER: dominance; 70% for willingness-to-pay threshold of €50,000/QALY gained).

CONCLUSIONS

We found no evidence for cost-effectiveness of the intervention in comparison to treatment as usual.

Poverty and health-related quality of life: a cross-sectional study in rural China

BACKGROUND

The association between poverty and health has been widely assessed. However, whether the association between poverty and health-related quality of life (HRQOL) holds among different groups is unknown. This study aimed to 1) assess the association between poverty and HRQOL among rural residents in China and 2) examine whether the association holds among different populations, thereby supporting policy-making and implementation.

METHODS

A multistage, stratified, random household survey was conducted with self-administered questionnaires. Matched samples were generated by the censored exact matching method to reduce selection bias between the poverty and comparison groups. We applied Tobit and ordinal logit regression models to evaluate the association between poverty and HRQOL measured by the EQ-5D-3 L among different groups.

RESULTS

The health utility score of the poverty group was 6.1% lower than that of comparison group (95% CI = - 0.085, - 0.037), with anxiety/depression being most common (95% CI = 1.220, 1.791). The association between poverty and HRQOL was significantly stronger among residents from central China, males, people who were middle-aged, elderly, highly educated, married, or widowed, those living far from healthcare facilities, and those without chronic disease. Male and highly educated subjects reported worse mobility, self-care, usual activities, pain/discomfort and anxiety/depression dimensions than the other respondents. Middle-aged (95% CI = 1.692, 2.851) and married respondents (95% CI = 1.692, 2.509) and respondents with chronic diseases (95% CI = 1.770, 2.849) were most affected in the anxiety/depression.

CONCLUSIONS

The HRQOL of individuals living in poverty is lower than that of the general population, and the mental health dimension is most affected by poverty among respondents who are middle-aged or married and respondents with chronic diseases. The identification of populations that are more affected by poverty is critical to improve their HRQOL. Various associations have indicated the need for integrated policies and specific decision-making.

Coastal proximity and mental health among urban adults in England: The moderating effect of household income

After adjusting for covariates, self-reported general health in England is higher among populations living closer to the coast, and the association is strongest amongst more deprived groups. We explored whether similar findings were present for mental health using cross-sectional data for urban adults in the Health Survey for England (2008-2012, N ≥25,963). For urban adults, living ≤1 km from the coast, in comparison to >50 km, was associated with better mental health as measured by the GHQ12. Stratification by household income revealed this was only amongst the lowest-earning households, and extended to ≤5 km. Our findings support the contention that, for urban adults, coastal settings may help to reduce health inequalities in England.
