Relationship between CD4 count and quality of life over time among HIV patients in Uganda: a cohort study

Psychosocial predictors of quality of life among women living with HIV/AIDS: a cross-sectional study in a VCT centre in Shiraz, Iran

PURPOSE

We aimed to assess psychosocial predictors of quality of life (QOL) among women living with HIV/AIDS (WLHIV). QOL has been considered as an important indicator in evaluating the outcome of psychological and physical healthcare in people living with HIV (PLHIV).

METHODS

This cross-sectional study was carried out from October 2021 to April 2022 at the Voluntary, Counselling, and Testing (VCT) center in Shiraz, Iran. A total of 452 WLHIV were included in this study. Socio-demographic and clinical data, social support (MSPSS questionnaire), food insecurity (HFIAS questionnaire), resilience (CD-RISC questionnaire), mental health status (DASS questionnaire), and QOL (WHOQOL-BREF questionnaire) were collected through direct interviews and patients' files at Shiraz VCT.

RESULTS

Physical and social relationships domains of QOL had the highest (60.48 ± 18.00) and lowest (36.76 ± 23.88) scores, respectively. Higher clinical stage, psychotropic substances use, having a husband infected with HIV, history of hypertension, and higher socioeconomic status had a significant relationship with some domains of QOL. The score of social support, food insecurity, resilience, and mental health status had a significant relationship with all domains of QOL.

CONCLUSION

Social relationships domain of QOL had the lowest scores in WLHIV. Also, the mental health status of WLHIV was more related to their QOL than the physical status related to HIV/AIDS. Interventions such as improving the mental health care and resilience skills of WLHIV, including their social network in counseling services to promote their social support, could help them to improve their QOL.

Determinants of health-related quality of life in people with Human Immunodeficiency Virus, failing first-line treatment in Africa

BACKGROUND

Antiretroviral treatment improves health related quality of life (HRQoL) of people with human immunodeficiency virus (PWH). However, one third initiating first-line treatment experience virological failure and the determinants of HRQoL in this key population are unknown. Our study aims to identify determinants of among PWH failing antiretroviral treatment in sub-Saharan Africa.

METHODS

We analysed data from a cohort of PWH having virological failure (> 1,000 copies/mL) on first-line ART in South Africa and Uganda. We measured HRQoL using the EuroQOL EQ-5D-3L and used a two-part regression model to obtain by-country analyses for South Africa and Uganda. The first part identifies risk factors that were associated with the likelihood of participants reporting perfect health (utility = 1) versus non-perfect health (utility < 1). The second part identifies risk factors that were associated with the EQ-5 L-3L utility scores for participants reporting non-perfect health. We performed sensitivity analyses to compare the results between the two-part model using tobit models and ordinary least squares regression.

RESULTS

In both countries, males were more likely to report perfect health and participants with at least one comorbidity were less likely to report perfect health. In South Africa, participants with side effects and in Uganda those with opportunistic infections were also less likely to report perfect health. In Uganda, participants with 100% ART adherence were more likely to report perfect health. In South Africa, high HIV viral load, experiencing ART side effects, and the presence of opportunistic infections were each associated with lower HRQoL, whereas participants with 100% ART adherence reported higher HRQoL. In Uganda participants with lower CD4 count had lower HRQoL.

CONCLUSION

Markers of advanced disease (opportunistic infection, high viral load, low CD4), side effects, comorbidities and lack of ART adherence negatively impacted HRQoL for PWH experiencing virological failure.

Quality of antiretroviral therapy services in Ghana: Implications for the HIV response in resource-constrained settings

Objective

Number of People Living with Human Immune-deficiency Virus in Ghana is over 300,000 and unmet need for antiretroviral therapy is approximately 60%. This study sought to determine the quality of antiretroviral therapy services in selected ART sites in Ghana using the input-process-outcome approach.

Methods

This is a descriptive cross-sectional case study that employed modified normative evaluation to assess quality of antiretroviral therapy services in the Oti and Volta regions of Ghana among People Living with HIV (n = 384) and healthcare providers (n = 16). The study was conducted from 11 March to 9 May 2019.

Results

Resources for managing HIV clients were largely available with the exception of viral load machines, reagents for CD4 counts, and antifungals such as Fluconazole and Cotrimoxazole. Patients enrolled on antiretroviral therapy within 2 weeks was 71% and clients retained in care within 2 weeks of enrolment was 90%. Approximately 26% of enrolled clients recorded viral load suppression; 33% of People Living with HIV who were not insured with the National Health Insurance Scheme paid for some antiretrovirals and cotrimoxazole. Adherence to ART and Cotrimoxazole were 95% and 88%, respectively, using pill count on their last three visits. Time spent with clinical team was among the worst rated (mean = 2.98, standard deviation = 0.54) quality indicators by patients contrary to interpersonal relationship with health provider which was among the best rated (mean = 3.25, standard deviation = 0.41) indicators.

Conclusion

Observed quality care gaps could potentially reverse gains made in HIV prevention and control in Ghana if not addressed timely; an important value addition of this study is the novel application of input-process-outcome approach in the context of antiretroviral therapy services in Ghana. There is also the need for policy dialogue on inclusion of medications for prophylaxis in antiretroviral therapy on the National Health Insurance Scheme to promote adherence and retention.

Multilevel ordinal model for CD4 count trends in seroconversion among South Africa women

BACKGROUND

Ordinal health longitudinal response variables have distributions that make them unsuitable for many popular statistical models that assume normality. We present a multilevel growth model that may be more suitable for medical ordinal longitudinal outcomes than are statistical models that assume normality and continuous measurements.

METHODS

The data is from an ongoing prospective cohort study conducted amongst adult women who are HIV-infected patients in Kwazulu-Natal, South Africa. Participants were enrolled into the acute infection, then into early infection subsequently into established infection and afterward on cART. Generalized linear multilevel models were applied.

RESULTS

Multilevel ordinal non-proportional and proportional-odds growth models were presented and compared. We observed that the effects of covariates can't be assumed identical across the three cumulative logits. Our analyses also revealed that the rate of change of immune recovery of patients increased as the follow-up time increases. Patients with stable sexual partners, middle-aged, cART initiation, and higher educational levels were more likely to have better immunological stages with time. Similarly, patients having high electrolytes component scores, higher red blood cell indices scores, higher physical health scores, higher psychological well-being scores, a higher level of independence scores, and lower viral load more likely to have better immunological stages through the follow-up time.

CONCLUSION

It can be concluded that the multilevel non-proportional-odds method provides a flexible modeling alternative when the proportional-odds assumption of equal effects of the predictor variables at every stage of the response variable is violated. Having higher clinical parameter scores, higher QoL scores, higher educational levels, and stable sexual partners were found to be the significant factors for trends of CD4 count recovery.

Modelling immune deterioration, immune recovery and state-specific duration of HIV-infected women with viral load adjustment: using parametric multistate model

BACKGROUND

CD4 cell and viral load count are highly correlated surrogate markers of human immunodeficiency virus (HIV) disease progression. In modelling the progression of HIV, previous studies mostly dealt with either CD4 cell counts or viral load alone. In this work, both biomarkers are in included one model, in order to study possible factors that affect the intensities of immune deterioration, immune recovery and state-specific duration of HIV-infected women.

METHODS

The data is from an ongoing prospective cohort study conducted among antiretroviral treatment (ART) naïve HIV-infected women in the province of KwaZulu-Natal, South Africa. Participants were enrolled in the acute HIV infection phase, then followed-up during chronic infection up to ART initiation. Full-parametric and semi-parametric Markov models were applied. Furthermore, the effect of the inclusion and exclusion viral load in the model was assessed.

RESULTS

Inclusion of a viral load component improves the efficiency of the model. The analysis results showed that patients who reported a stable sexual partner, having a higher educational level, higher physical health score and having a high mononuclear component score are more likely to spend more time in a good HIV state (particularly normal disease state). Patients with TB co-infection, with anemia, having a high liver abnormality score and patients who reported many sexual partners, had a significant increase in the intensities of immunological deterioration transitions. On the other hand, having high weight, higher education level, higher quality of life score, having high RBC parameters, high granulocyte component scores and high mononuclear component scores, significantly increased the intensities of immunological recovery transitions.

CONCLUSION

Inclusion of both CD4 cell count based disease progression states and viral load, in the time-homogeneous Markov model, assisted in modeling the complete disease progression of HIV/AIDS. Higher quality of life (QoL) domain scores, good clinical characteristics, stable sexual partner and higher educational level were found to be predictive factors for transition and length of stay in sequential adversity of HIV/AIDS.

Multivariate multilevel modeling of quality of life dynamics of HIV infected patients

BACKGROUND

Longitudinal quality of life (QoL) is an important outcome in many chronic illness studies aiming to evaluate the efficiency of care both at the patient and health system level. Although many QoL studies involve multiple correlated hierarchical outcome measures, very few of them use multivariate modeling. In this work, we modeled the long-term dynamics of QoL scores accounting for the correlation between the QoL scores in a multilevel multivariate framework and to compare the effects of covariates across the outcomes.

METHODS

The data is from an ongoing prospective cohort study conducted amongst adult women who were HIV-infected and on the treatment in Kwazulu-Natal, South Africa. Independent and related QoL outcome multivariate multilevel models were presented and compared.

RESULTS

The analysis showed that related outcome multivariate multilevel models fit better for our data used. Our analyses also revealed that higher educational levels, middle age, stable sex partners and higher weights had a significant effect on better improvements in the rate of change of QoL scores of HIV infected patients. Similarly, patients without TB co-infection, without thrombocytopenia, with lower viral load, with higher CD4 cell count levels, with higher electrolytes component score, with higher red blood cell (RBC) component score and with lower liver abnormality component score, were associated with significantly improved the rate of change of QoL, amongst HIV infected patients.

CONCLUSION

It is hoped that the article will help applied researchers to familiarize themselves with the models and including interpretation of results. Furthermore, three issues are highlighted: model building of multivariate multilevel outcomes, how this model can be used to assess multivariate assumptions, involving fixed effects (for example, to examine the size of the covariate effect varying across QoL domain scores) and random effects (for example, to examine the rate of change in one response variable associated to changes in the other).

Association Between Immunologic and Virologic Functioning and Health-Related Quality of Life Among People Living with HIV, Tehran, Iran

BACKGROUND

With recent progress in the treatment of people living with HIV (PLWH) and their increased rate of survival, health-related quality of life (HRQoL) has become an important issue.

OBJECTIVE

In the present study, we aimed to investigate the association of current CD4 cell count, baseline CD4 cell count, nadir CD4 cell count, and plasma viral load with health-related quality of life in PLWH.

METHODS

Participants were 67 PLWH who were under the treatment of antiretroviral therapy (ART) in Imam Khomeini Hospital of Tehran, Iran in 2016. Participants were divided into the two groups with high and low levels of current CD4 cell count, baseline CD4 cell count, nadir CD4 cell count and plasma viral load. We used independent sample t-test for data analysis using SPSS 22 software.

RESULTS

Our results demonstrated that for current CD4 cell count, the group differences were significant for total scores of HRQoL (P=0.028), also in the components of physical functioning (P=0.032), role limitation due to physical health problems (P=0.006), and role limitation due to emotional problems (P=0.009). Our data analysis showed that for baseline CD4 cell count (P=0.62), nadir CD4 cell count (P=0.29), and viral load group (P=0.78), the differences were not significant for HRQoL.

CONCLUSION

Knowing the association between current CD4 count and health-related quality of life, adherence to ART might be a motivator for PLWH to enhance their health-related quality of life.

Social and demographical determinants of quality of life in people who live with HIV/AIDS infection: evidence from a meta-analysis

The aim of this meta-analysis is to summarize the available evidence on the social and demographic determinants of health-related quality of life (QoL) for HIV-infected populations in order to provide a direction to policy makers, planners, and program developers on how best to use their resources to improve the QoL of HIV-infected people.PubMed, Science Direct, Web of Science, and Cochrane electronic databases were searched (up to February 2017) to identify the relevant studies. A meta-analysis was conducted with procreate polled odds ratios (ORs and β) and the confidence intervals of 95% on determining factors of QoL in social and demographic terms. Random effect model was applied to calculate pooled estimation, due to varied sampling methods of researches.In total, 5607 papers were identified from 4 databases and additional search in reference lists. Of these, 2107 articles were selected for full-text review. We included 19 studies that met the eligibility criteria. The pooled effect size shows a relative positive impact of social support for QoL among HIV/AIDS patients and its lower boundary is about 0.61 and the higher about 1.49. The pooled effect size has a considerable negative impact stigma on people who live with HIV/AIDS (PWLHs') QoL ranges from -0.34 to -0.32. Low socioeconomic status (poverty situation) was found to have a degenerative impact with PWLHs' QoL. Our finding indicates an association between younger 35 and QoL is negative with a relatively wide range, the minimum level of education has a weak association with PWLHs' QoL (ES: 0.14-0.2).There are several sociodemographic determinants of QoL among PWLHs and in this study, we found that stigma, low level of socioeconomic status, and being younger than 35 years old have a negative association with QoL, while the social support showed a positive association and a minimum level of education did not show a rigorous negative or positive association.

Factors influencing the quality of life in persons living with human immunodeficiency virus infection in Almaty, Kazakhstan

The study purpose was to determine the factors associated with health-related quality of life (HRQoL) among people living with HIV (PLHIV) in Kazakhstan. A convenience sample of 531 adult PLHIV registered at the Almaty City AIDS Center was used for this cross-sectional study. HRQoL data were collected with the World Health Organization’s Quality of Life HIV brief questionnaire, depression – with Patient Health Questionnaire-9, and clinical data were retrieved from medical records. Multivariate logistic and Tobit censored regressions were used to examine the relationship of socio-demographic, behavioral, and clinical factors with HRQoL and the six specific HRQoL domains: 35.8% of participants did not report good HRQoL. The following variables were identified as independent predictors of poor HRQoL: probable depression (adjusted odds ratio [AOR] 13.42, 95% confidence interval [CI]: 4.56–39.52); history of injecting drug use (AOR 2.10, 95% CI: 1.40–3.14); CD4+ T-cell count <200 cells/mm³ (AOR 2.17, 95% CI: 1.30–3.62); previously married status (AOR 2.23, 95% CI: 1.16–4.28); and co-infection with tuberculosis, syphilis, toxoplasmosis, Chlamydia, herpes simplex, or cytomegalovirus (AOR 1.59, 95% CI: 1.06–2.39). HRQoL of PLHIV in Almaty was independently influenced by several factors. An interdisciplinary approach is needed in planning healthcare and social services addressing improvement of HRQoL among PLHIV.

Cost-effectiveness and budget impact of immediate antiretroviral therapy initiation for treatment of HIV infection in Côte d'Ivoire: A model-based analysis

Introduction

The Temprano and START trials provided evidence to support early ART initiation recommendations. We projected long-term clinical and economic outcomes of immediate ART initiation in Côte d’Ivoire.

Methods

We used a mathematical model to compare three potential ART initiation criteria: 1) CD4 <350/μL (ART<350/μL); 2) CD4 <500/μL (ART<500/μL); and 3) ART at presentation (Immediate ART). Outcomes from the model included life expectancy, 10-year medical resource use, incremental cost-effectiveness ratios (ICERs) in $/year of life saved (YLS), and 5-year budget impact. We simulated people with HIV (PWH) in care (mean CD4: 259/μL, SD 198/μL) and transmitted cases. Key input parameters to the analysis included first-line ART efficacy (80% suppression at 6 months) and ART cost ($90/person-year). We assessed cost-effectiveness relative to Côte d’Ivoire’s 2017 per capita annual gross domestic product ($1,600).

Results

Immediate ART increased life expectancy by 0.34 years compared to ART<350/μL and 0.17 years compared to ART<500/μL. Immediate ART resulted in 4,500 fewer 10-year transmissions per 170,000 PWH compared to ART<350/μL. In cost-effectiveness analysis, Immediate ART had a 10-year ICER of $680/YLS compared to ART<350/μL, ranging from cost-saving to an ICER of $1,440/YLS as transmission rates varied. ART<500/μL was “dominated” (an inefficient use of resources), compared with Immediate ART. Immediate ART increased the 5-year HIV care budget from $801.9M to $812.6M compared to ART<350/μL.

Conclusions

In Côte d’Ivoire, immediate compared to later ART initiation will increase life expectancy, decrease HIV transmission, and be cost-effective over the long-term, with modest budget impact. Immediate ART initiation is an appropriate, high-value standard of care in Côte d’Ivoire and similar settings.

Change in multidimensional problems and quality of life over three months after HIV diagnosis: a multicentre longitudinal study in Kenya and Uganda

Background

Evidence on patient-reported outcomes of newly diagnosed HIV patients is scarce, and largely cross-sectional. This prospective cohort study describes the prevalence of, and changes in, patient-reported outcomes in the three months after HIV diagnosis, in 11 HIV outpatient centres in Kenya and Uganda.

Methods

Adults were recruited within 14 days of result, completing self-report measures four times at monthly intervals. Multilevel mixed-effects linear regression (quality of life continuous outcomes) and ordinal logistic regression (symptoms and concerns categorical outcomes) modelled change over time, with repeated observations grouped within individuals adjusted for demographic/clinical characteristics, and multiple imputation for missing data.

Results

438 adults were enrolled and 234 (53·4%) initiated ART. Improvement was found for MOS-HIV physical health (from 46·3 [95% CI 45·1–47·3], to 53·7 [95% CI 52.8–54·6], p < 0.001), and mental health (from 46·4 [95% CI 45·5–47·3] to 54·5 [95% CI 53·7–55·4], p < 0.001). POS subscale ‘interpersonal problems’ improved but remained burdensome (OR = 0·91, 95% CI = 0·87–0·94, p < 0.001; 22·7% reported severe problems at final time point). The scores for the existential POS subscale (OR = 0·95, 95% CI = 0.90–1·00, p = 0.056) and physical/psychological problems POS subscale (OR = 0·97, 95% CI = 0.92–1·02, p = 0.259) did not improve.

Participants who initiated ART had worsening physical/psychological (OR = 0·64, 95% CI = 0·41–0·99, p = 0·045) and interpersonal problems (OR = 0·64, 95% CI = 0·42–0·96, p = 0·033).

Conclusion

Although some self-reported outcomes improve over time, burden of interpersonal problems remains substantial and existential concerns do not improve.

Depression, social support, and stigma as predictors of quality of life over time: results from an Asha-based HIV/AIDS intervention in India

Quality of life (QOL) is associated with better outcomes in HIV/AIDS populations. We explored predictors of improved QOL over time in 600 Women Living with HIV/AIDS (WLH/A) in India [mean age = 34.31, SD = 6.97], enrolled in a nurse-led-Asha (Accredited Social Health Activist) intervention. Trained local interviewers ascertained self-report data at baseline and six-month follow-up (post-intervention). Latent Class Analysis (LCA) identified constellations of responses on psychosocial indicators (depression, social support, internalized stigma and stigma fears); their relationship with QOL over time was examined. We identified three classes: Class 1) Highest Social Resources/Lowest Depression; Class 2) Some Social Resources/Highest Depression; and Class 3) Lowest Social Resources/Higher Depression. At baseline, Class 3 reported the lowest QOL (M = 0.25, SD = 0.26); Class 1 reported the highest (M = 0.37, SD = 0.33). Class 2's QOL did not differ from Class 3's QOL, likely due to the potent effects of high depression. At six-month follow-up, all groups reported improved QOL; class membership no longer predicted variability (contrast between Class 2 and 1 = -0.05, 95% CI = -0.14, 0.04; contrast between Class 3 and 1 = 0.01, 95% CI = -0.03, 0.05; contrast between Class 3 and 2 = 0.07, 95% CI = -0.02, 0.16). Psychosocial indicators are important predictors of QOL; an Asha-supported approach may have broad applicability to improve QOL in WLH/A in India.

Validation of heart failure quality of life tool and usage to predict all-cause mortality in acute heart failure in Uganda: the Mbarara heart failure registry (MAHFER)

BACKGROUND

The health-related quality of life (HRQoL) is an important treatment goal that could serve as low-cost prognostication tool in resource poor settings. We sought to validate the Kansas City Cardiomyopathy Questionnaire (KCCQ) and evaluate its use as a predictor of 3 months all-cause mortality among heart failure participants in rural Uganda.

METHODS

The Mbarara Heart Failure Registry Cohort study observes heart failure patients during hospital stay and in the community in rural Uganda. Participants completed health failure evaluations and HRQoL questionnaires at enrollment, 1 and 3 months of follow-up. We used Cronbach's alpha coefficients to define internal consistency, intraclass correlation coefficients as a reliability coefficient, and Cox proportional hazard models to predict the risk of 3 months all-cause mortality.

RESULTS

Among the 195 participants who completed HRQoL questionnaires, the mean age was 52 (standard deviation (SD) 21.4) years, 68% were women and 29% reported history of hypertension. The KCCQ had excellent internal consistency (87% Cronbach alpha) but poor reliability. Independent predictors of all-cause mortality within 3 months included: worse overall KCCQ score (Adjusted Hazard ratio (AHR) 2.9, 95% confidence interval (CI) 1.1, 8.1), highest asset ownership (AHR 3.6, 95% CI 1.2, 10.8), alcoholic drinks per sitting (AHR per 1 drink 1.4, 95% CI 1.0, 1.9), New York Heart Association (NYHA) functional class IV heart failure (AHR 2.6, 95% CI 1.3, 5.4), estimated glomerular filtration rate (eGFR) 30 to 59 ml/min/1.73 m2 (AHR 3.4, 95% CI 1.1, 10.8), and eGFR less than 15 ml/min/1.73 m2 (AHR 2.7, 95% CI 1.0, 7.1), each 1 pg/mL increase in Brain Natriuretic Peptide (BNP) (AHR, 1.0, 95% CI 1.0, 1.0), and each 1 ng/mL increase in Creatine-Kinase MB isomer (CKMB) (AHR 1.0, 95% CI 1.0, 1.1).

CONCLUSION

The KCCQ showed excellent internal consistency. Worse overall KCCQ score, highest asset ownership, increasing alcoholic drink per sitting, NYHA class IV, decreased estimated glomerular filtration rate, BNP, and CKMB predicted all-cause mortality at 3 months. The KCCQ could be an additional low-cost tool to aid in the prognostication of acute heart failure patients.

Major depression disorder trajectories and HIV disease progression: results from a 6-year outpatient clinic cohort

Contradictory evidence exists on the role of Major depression disorder (MDD) as a predictor of human immunodeficiency virus (HIV) disease progression, particularly regarding the effect of MDD presence versus pattern of illness. The objective of this study was to examine whether MDD status and pattern of illness differentially predict HIV disease progression. Retrospective cohort data from a six-year follow-up of HIV patients at an outpatient clinic were analyzed. MDD trajectories were identified by latent class growth analysis and generalized linear mixed models were used to examine their relation to low CD4+ T-lymphocyte counts (<200 cells/μL) during follow-up. Among 1,494 HIV patients, four MDD trajectory groups were identified: Low-Chronic, Moderate-Ascending, High-Episodic, and High-Chronic. Trajectory group membership was predicted by male sex (P = .04), minority race (P < .01), older age (P < .01) and low baseline CD4 count (P = .04). The High-Chronic group had lower odds of having a low CD4 count than the Low-Chronic group (adjusted Odds Ratio [aOR]: 0.63; 95%CI: 0.49-0.81) while the Moderate-Ascending group had higher odds (aOR: 1.53; 95%CI: 1.08-2.19). The odds of having a low CD4 count were higher among male (aOR: 1.25; 95%CI: 1.03-1.52), minority races (American Indian [aOR: 1.85; 95%CI: 1.38-2.49] and African Americans [aOR: 1.58; 95%CI: 1.33-1.87]), Hispanic (aOR: 1.52; 95%CI: 1.06-2.18), and divorced/separated patients (aOR: 1.62; 95%CI: 1.16-2.28) but decreased over time (P < .01) across trajectory groups. In this study, because MDD trajectories and CD4 counts were determined based on secondary data abstracted from electronic medical records, the results should be interpreted cautiously due to the potential for selection and misclassification bias. Overall, study findings suggest the pattern of MDD illness among HIV patients can be classified into clinically meaningful trajectory groups that appear to be programmed by known risk factors, and are useful for predicting HIV disease progression. Targeted interventions among at-risk patients may be critical to altering MDD illness patterns and curtailing HIV disease progression.

Psychometric properties of the Chinese version of the WHOQOL-HIV BREF to assess quality of life among people living with HIV/AIDS: a cross-sectional study

OBJECTIVES

This study aims to assess the psychometric properties of the Chinese version of the WHOQOL-HIV BREF.

DESIGN

Cross-sectional study.

SETTING

Centers for Disease Control and Prevention and infectious disease hospitals in three Chinese provinces.

PARTICIPANTS

Sample of 1100 people living with HIV/AIDS (PLWHA).

INTERVENTIONS

We recruited 1100 PLWHA to evaluate their quality of life (QOL) using the WHOQOL-HIV BREF. Of these participants, 57 were randomly selected to repeat the QOL evaluation 2 weeks later.

MAIN OUTCOME MEASURES

The reliability of the WHOQOL-HIV BREF was assessed in terms of its internal consistency and test-retest reliability. The construct, concurrent, convergent, discriminant and known-group validity were also analysed. In addition, the factorial invariance across genders was assessed.

RESULTS

Cronbach's α coefficient for the overall scale was 0.93. Except for the spirituality domain, which had an α below 0.70 (0.66), the other five domains showed adequate internal consistency. The test-retest reliability revealed a statistically significant intraclass correlation coefficient of 0.72-0.82 (p<0.001). Confirmatory factor analysis found that the six-domain structure produced an acceptable fit to the data. The instrument showed factorial invariance across gender groups. All domains were significantly correlated with the general items and the SF-36 (p<0.01). The correlation coefficients were >0.40 (r=0.40-0.67), except for the association between the spirituality domain and two general items (QOL: r=0.33; health status: r=0.36). Subjects with lower CD4 counts had lower scores for all domains (p<0.05). Symptomatic participants had significantly lower scores than asymptomatic participants on the physical, psychological and independence domains (p<0.05).

CONCLUSIONS

The WHOQOL-HIV BREF revealed good psychometric characteristics among Chinese PLWHA. These findings offer promising support for the use of the WHOQOL-HIV BREF as a measure of QOL among Chinese PLWHA and in cross-cultural comparative studies on QOL.

Health-related quality of life and associated factors in people with HIV: an Irish cohort study

Background

Considering the chronic and debilitating nature of HIV infection, health-related quality of life (HRQoL) is an important patient-reported clinical outcome to better understand the effects of this infection and its treatment on patients’ lives. The purpose of this study was to assess the HRQoL and its association with sociodemographic, behavioural, clinical, nutrition-related factors and social support in an Irish HIV cohort.

Methods

A cross-sectional, prospective study using the Medical Outcomes Study HIV Health survey assessed the 10 dimensions of HRQoL and summarised as Physical Health Summary (PHS) and Mental Health Summary (MHS) scores. Participants were categorised as having good or poor PHS and MHS using the standardised mean score of 50. The variables independently associated with PHS and MHS were identified using multivariable logistic regression models.

Results

Overall, 521 participants completed the HRQoL questionnaire. The median (IQR) PHS and MHS scores were 56 (47–60) and 51 (41–58) respectively. All the covariate groups had lower MHS than PHS. Participants with symptoms of HIV reported the lowest median (IQR) PHS score 44.7 (32.–54.5) and MHS score 36.1 (28.6–48.4). Of the 10 dimensions of HRQoL, the lowest scores were for the energy level and general health. Symptoms of HIV, co-morbidities, social support, employment and ethnicity had independent association with both PHS and MHS. Gender, education, alcohol intake and HIV-complications were associated with PHS. Age, illicit drugs, BMI and malnutrition were associated with MHS. However, CD4 count and viral load were not independently associated with PHS and MHS in multivariable regression models.

Conclusion

Overall, HIV-infected people in this cohort had an average level of HRQoL. However, it is impaired in people with symptoms and co-morbidities, and not independently associated with CD4 and viral load. Alleviating HIV symptoms and preventing co-morbidities are important in managing HIV. Providing psychosocial supports for behaviour modification and return to work or exploring new opportunities will help to improve HRQoL. Healthcare providers and policy makers need to plan and implement programs to routinely assess the HRQoL in a systematic method to facilitate a holistic management of HIV.
