Reliability and validity of the SF-36 in HIV-infected homeless and marginally housed individuals

Vision Problems As a Contributor to Lower Engagement in Care Among Aging Men Living with HIV

PURPOSE

To investigate vision impairment as a barrier to engagement in medical care among aging persons living with HIV (PLWH) who experience multimorbidity and complex care needs.

SETTING

Multicenter AIDS Cohort Study (MACS), a prospective observational cohort of aging PLWH men.

METHODS

We examined relationships of self-reported vision difficulty with indicators of care engagement: 1) adherence to HIV antiretroviral therapy (ART; defined as taking ≥95% of medications); 2) self-reported avoidance of medical care; 3) self-reported tendency to ask a doctor questions about care (>2 questions at a medical visit), as well as with quality of life. A modified version of the National Eye Institute Vision Function Questionnaire was administered at three semi-annual visits (from October 2017 to March 2019) to assess difficulty performing vision-dependent tasks.

RESULTS

We included 1063 PLWH (median age 57 years, 31% Black). Data on care engagement outcomes were analyzed using repeated measures logistic regression with generalized estimating equations adjusted for race, and at visit values for age, education level, depressive symptoms, alcohol use, and smoking status. Compared to no vision difficulty, those reporting moderate to extreme vision difficulty on at least one task had 2.2 times higher odds (95% CI: 1.4, 3.4) of having less than optimal ART adherence, 1.9 times higher odds (95% CI: 1.1, 3.4) of avoiding necessary medical care and median quality of life scores 8 points lower.

CONCLUSION

These findings suggest vision impairment decreases medical care engagement including HIV care and quality of life among aging PLWH.

Combined effects of social isolation and loneliness on patient-reported outcomes in older adults with HIV

Social isolation exists when one has limited contact with others and is distinct from loneliness, an affective state on the perception of isolation. Less is known about the combined effects of social isolation and loneliness (SI/L) in older persons with HIV (OPWH). Using cross-sectional data on OPWH (age ≥50; N = 146), we assessed the overlap between SI/L and the separate and combined effects of SI/L on patient-reported outcomes (quality-of-life [QoL], HIV-related stigma, and depressive symptoms). Social isolation and loneliness were assessed using Social Network Index and the PROMIS-Social Isolation Scale, respectively, and based on each score, participants were grouped into four categories: "lonely only", "isolated only", "lonely+isolated", or "neither". Among participants (mean age = 56.53), 26.7% were considered "lonely only", 12.3% were "isolated only", 15.1% were "lonely+isolated", and 45.9% were "neither". Adjusted regression models showed that lonely+isolated group had more depressive symptoms and lower QoL than those considered "neither" or "isolated only" (p < .001) and that. The adjusted proportional odds model showed that the odds of stigma were 1.22 and 6.06 higher than those considered "neither" (p < .001) or "lonely only" (p = .016). Results demonstrate the combined effects of SI/L on patient-reported outcomes among OPWH. Findings highlight the need for approaches targeting OPWH who are lonely and isolated.

Social network size and its relationship to domains of quality-of-life among older persons living with HIV

Gerontological research suggests that social network characteristics are key elements of successful aging as they are related to a positive quality-of-life (QoL). Less is known about the social networks of persons aging with HIV. To describe social network characteristics and assess the effect of social network size on QoL, a sample of 146 OPWH (age ≥50) was recruited from an outpatient HIV clinic in Atlanta, GA. Social network size was assessed using Cohen's social network index (SNI). Domains of QoL (physical, emotional, and social) were assessed using the RAND-36. Descriptive analyses were used to determine the frequency of contact within social networks and multivariable regression models were used to assess the relationship between SNI and three domains of QoL controlling for potential covariates. Participants were predominantly male (60%), heterosexual (63%), and African American (86%). Regular contact occurred most frequently with friends (82%) and relatives (77%). Multivariable modeling revealed that SNI explained 58% of the variance in emotional QoL (R2 = 0.58, F(8, 137) =  25.48, p < .001). Findings provide basis for potential interventions focused on the specific social network to improve emotional QoL of this vulnerable population.

Non-alcoholic fatty liver disease is not associated with impairment in health-related quality of life in virally suppressed persons with human immune deficiency virus

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in persons with HIV (PWH) (HIV-NAFLD). It is unknown if HIV-NAFLD is associated with impairment in health-related quality of life (HRQOL). We examined HRQOL in PWH with and without NAFLD, compared HRQOL in HIV- versus primary NAFLD, and determined factors associated with HRQOL in these groups. Prospectively enrolled 200 PWH and 474 participants with primary NAFLD completed the Rand SF-36 assessment which measures 8 domains of HRQOL. Individual domain scores were used to create composite physical and mental component summary scores. Univariate and multivariate analyses determined variables associated with HRQOL in PWH and in HIV- and primary NAFLD. In PWH, 48% had HIV-NAFLD, 10.2% had clinically significant fibrosis, 99.5% were on antiretroviral therapy, and 96.5% had HIV RNA <200 copies/ml. There was no difference in HRQOL in PWH with or without NAFLD. Diabetes, non-Hispanic ethnicity, and nadir CD4 counts were independently associated with impaired HRQOL in PWH. In HIV-NAFLD, HRQOL did not differ between participants with or without clinically significant fibrosis. Participants with HIV-NAFLD compared to those with primary NAFLD were less frequently cisgender females, White, more frequently Hispanic, had lower BMI and lower frequency of obesity and diabetes. HRQOL of individuals with HIV-NAFLD was not significantly different from those with primary NAFLD. In conclusion, in virally suppressed PWH, HRQOL is not different between participants with or without HIV-NAFLD. HRQOL is not different between HIV-NAFLD and primary NAFLD.

Psychometric properties of self-reported measures of health-related quality of life in people living with HIV: a systematic review

Objective

To identify and assess the psychometric properties of patient-reported outcome measures (PROMs) of health-related quality of life (HRQoL) in people living with HIV (PLWH).

Methods

Nine databases were searched from January 1996 to October 2020. Methodological quality was assessed by using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) Risk of Bias Checklist. We used the COSMIN criteria to summarize and rate the psychometric properties of each PROM. A modified Grading, Recommendations, Assessment, Development, and Evaluation (GRADE) system was used to assess the certainty of evidence.

Results

Sixty-nine studies reported on the psychometric properties of 30 identified instruments. All studies were considered to have adequate methodological quality in terms of content validity, construct validity, and internal consistency. Limited information was retrieved on cross-cultural validity, criterion validity, reliability, hypothesis testing, and responsiveness. High-quality evidence on psychometric properties was provided for the Medical Outcomes Study HIV Health Survey (MOS-HIV), the brief version of the World Health Organization's Quality of Life Instrument in HIV Infection (WHOQoL-HIV-BREF), 36-Item Short Form Survey (SF-36), Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQoL-HIV), and WHOQoL-HIV.

Conclusions

The findings from the included studies highlighted that among HIV-specific and generic HRQoL PROMs, MOS-HIV, WHOQoL-HIV-BREF, SF-36, MQoL-HIV, and WHOQoL-HIV are strongly recommended to evaluate HRQoL in PLWH in research and clinics based on the specific aims of assessments and the response burden for participants.

Prevalence and Consequences of Perceived Vision Difficulty in Aging Adults with HIV Infection

PURPOSE

Despite well-known ocular complications of HIV-related immune suppression, few studies have examined the prevalence and consequences of visual impairment among aging long-term survivors of HIV.

DESIGN

Retrospective cohort study.

METHODS

Aging HIV-infected (HIV+) men who have sex with men (MSM) and HIV-uninfected (HIV-) MSM controls reported their difficulty performing 6 vision-dependent tasks (difficulty defined as: no, a little, moderate, and extreme difficulty). Relationships were examined using logistic regression, regressing each outcome separately on categorical visual function responses, with missing data multiply imputed.

RESULTS

There were 634 age-matched pairs for a total sample of 1,268 MSM of 1,700 MSM with available data. The median age was 60 years old (interquartile range [IQR], 54, 66), and 23% were African American. Among HIV+ men, 95% were virally suppressed (viral load <400 copies/mL). HIV+ men were more likely to report moderate or extreme difficulty performing at least 1 task (21% for HIV+ compared to 13% for HIV-; P < .01). Participants reporting extreme vision-related difficulty performing at least 1 task had 11.2 times the odds of frailty (95% confidence interval [CI], 5.2-23.9), 2.6 times the odds of a slow gait speed (95% CI, 1.4-4.8), and 3.2 times the odds of impaired instrumental activities of daily living (95% CI: 1.6-6.3) compared to those reporting no vision-related difficulty on any task.

CONCLUSIONS

Perceived vision difficulty was more common among older HIV+ MSM than age-matched HIV- MSM controls and was associated with higher risk of depression and physical function loss among MSM.

Health-related quality of life and related factors among chronically homeless adults living in different permanent supportive housing models: a cross-sectional study

PURPOSE

Permanent supportive housing (PSH) is an effective intervention to improve residential stability and reduce the utilization of costlier healthcare services for the chronically homeless. However, there has been little focus on health-related quality of life (HRQL) once they enter PSH, and the potential influence of other factors including the PSH model. Study results can shed light on the HRQL of the PSH population and inform strategies to improve PSH program effectiveness in this area.

METHODS

In this cross-sectional study, survey methods were used to assess the HRQL of PSH residents in the Chicago metropolitan area. The survey also included questions on socio-demographics, health behaviors, housing and neighborhood characteristics, and housing satisfaction. The SF-36 was used to obtain physical (PCS) and mental component summary (MCS) scores for HRQL. Other variables were selected using the Wilson and Cleary HRQL model. Statistical analyses included summary statistics, bivariate analyses, and fully adjusted linear regression models.

RESULTS

The study sample included 855 adults currently in PSH. The sample was predominantly African American men with an average age of 53 years. Mean scores for PCS and MCS were 39.4 and 46.1, respectively, (out of 100). In adjusted analyses, older age and being on disability were associated with worse PCS. Having HIV was associated with better PCS. Being non-Hispanic Black, living in fixed-sited housing, and being in PSH for longer durations were associated with better MCS. More depressive symptoms was associated with worse PCS and MCS.

CONCLUSION

While both aspects of the PSH model (housing configuration and service provision) were initially associated with HRQL in unadjusted analyses, housing configuration was the only PSH model variable that remained significant once accounting for other factors. Depressive symptomology and the social environment also appear to be important correlates of HRQL and are potential areas to target in PSH programs.

Health-related quality of life among adults living with HIV: a cross-sectional survey in Armenia

Few studies have examined health-related quality of life (HRQoL) among people living with HIV (PLWHIV) in Eastern Europe and Central Asia. We conducted a cross-sectional survey of 180 PLWHIV aged 18 years+ in Armenia who were on cART and used the 36-Item Short-Form Health Survey to assess HRQoL. The highest HRQoL domain score was 85.3 (SD 24.7) for physical functioning, followed by 82.1 (SD 25.0) for pain, 77.9 (SD 24.2) for social functioning, 76.4 (SD 39.6) for emotional role-functioning, 71.1 (SD 39.7) for physical role-functioning, and 64.0 (SD 20.3) for energy/fatigue, 63.7 (SD 22.7) for emotional well-being and 63.4 for general health 63.4 (SD 21.2). In the physical domain, chronic comorbidities and low emotional support were associated with worse physical functioning, physical role-functioning, general health and pain scores (p < 0.05). Unemployment and hepatitis C coinfection were associated with worse physical role functioning and pain scores (p < 0.01). As for mental HRQoL, we found that unemployment, chronic comorbidities, and lower emotional support were associated with poorer emotional well-being, energy, and emotional role-functioning scores (p < 0.05). These findings suggest that improved social support, employment opportunities, mental health services and integrated care for noncommunicable comorbidities may improve HRQoL in Armenia and similar settings.

Frailty in men living with HIV: a cross-sectional comparison of three frailty instruments

BACKGROUND

Potent antiretroviral treatment has resulted in near normal life expectancy for people living with HIV. Consequently, there is an increased focus on comorbidities, frailty and quality of life.

METHODS

We assessed and compared the prevalence of frailty, associated factors and relationship with quality of life in older Australian men living with HIV in a cross-sectional study using three frailty measurements. The Frailty Phenotype, Frailty Index and Edmonton Frail Scale were applied to 93 HIV-infected men aged over 50 years, on antiretroviral therapy. Multivariable ordinal logistic regression was used to analyse the associations of frailty with covariates and quality of life.

RESULTS

The prevalence of frailty was 10.8% (n=10) using the Frailty Phenotype; 22.6% (n=21) using the Frailty Index and 15.1% (n=14) using the Edmonton Frail Scale. Frailty Phenotype-defined pre-frailty/frailty was associated with pre-1996 ART initiation (OR, 3.56; CI, 1.23, 10.36; P=0.020) and depression (OR, 3.74; CI, 1.24, 11.27; P=0.019). Osteoporosis, serious non-AIDS events and AIDS were associated with Frailty Index-defined frailty (OR, 4.84, CI, 1.27, 18.43, P=0.021; OR, 4.27, CI, 1.25, 14.58, P=0.020; OR, 4.62, CI, 1.30, 16.45, P=0.018, respectively) and Edmonton Frail Scale-defined frailty (OR, 7.51; CI, 1.55, 36.42; P=0.012; OR, 7.71; CI, 1.62, 36.75; P=0.010; OR, 8.53; CI, 1.70, 42.73; P=0.009, respectively), independent of age and current CD4⁺ T-cell count. Frailty, defined by any of the instruments, was significantly associated with poorer quality of life (P<0.001).

CONCLUSIONS

Identifying frailty is an increasingly important contemporary consideration of HIV care related to ageing and quality of life.

Convergent validity of the EQ-5D-3L in a randomized-controlled trial of the Housing First model

BACKGROUND

Health utility assessments are important for economic evaluations but few instruments have been validated in homeless people with mental illness. We examined the convergent validity of the EuroQol-5 Dimension 3-level questionnaire (EQ-5D-3L) as a measure of quality of life in homeless adults with mental illness.

METHODS

Data were from Toronto participants in At Home/Chez Soi, a 24-month randomized controlled trial of Housing First (immediate access to scattered site housing and mental health support services) compared to treatment as usual for homeless adults with a mental disorder (n = 575). Participants completed the EQ-5D-3L at 6 month intervals. We tested convergent validity, hypothesizing strong correlation (r > 0.6) with the Lehman Quality of Life Interview 20 (QOLI-20) index and moderate correlations (r > 0.3) with the Colorado Symptom Index (CSI), Recovery Assessment Scale (RAS), and number of comorbidities. We also examined correlations between EQ-5D-3L scores and the QOLI-20 over time using a linear mixed-effects model.

RESULTS

The EQ-5D-3L was not strongly correlated with the QOLI-20 (r ranged from 0.31-0.52 at various time points). The EQ-5D-3L was moderately correlated with the CSI, RAS, and number of comorbidities. The Snijders/Bosker r² for longitudinal validity between the EQ-5D-3L and QOLI-20 within subjects over time was 0.2094 (square-root r = 0.4576).

CONCLUSIONS

The EQ-5D-3L did not demonstrate strong convergent validity in homeless people with mental illness but was moderately correlated with several instruments. Further research is warranted to determine the optimal method for measuring health utilities in this population.

Service provision for older homeless people with memory problems: a mixed-methods study

Background

Early or timely recognition of dementia is a key policy goal of the National Dementia Strategy. However, older people who are homeless are not considered in this policy and practice imperative, despite their high risk of developing dementia.

Objectives and study design

This 24-month study was designed to (1) determine the prevalence of memory problems among hostel-dwelling homeless older people and the extent to which staff are aware of these problems; (2) identify help and support received, current care and support pathways; (3) explore quality of life among older homeless people with memory problems; (4) investigate service costs for older homeless people with memory problems, compared with services costs for those without; and (5) identify unmet needs or gaps in services.

Participants

Following two literature reviews to help study development, we recruited eight hostels – four in London and four in North England. From these, we first interviewed 62 older homeless people, exploring current health, lifestyle and memory. Memory assessment was also conducted with these participants. Of these participants, 47 were included in the case study groups – 23 had ‘memory problems’, 17 had ‘no memory problems’ and 7 were ‘borderline’. We interviewed 43 hostel staff who were participants’ key workers. We went back 3 and 6 months later to ask further about residents’ support, service costs and any unmet needs.

Findings

Overall, the general system of memory assessment for this group was found to be difficult to access and not patient-centred. Older people living in hostels are likely to have several long-term conditions including mental health needs, which remain largely unacknowledged. Participants frequently reported experiences of declining abilities and hostel staff were often undertaking substantial care for residents.

Limitations

The hostels that were accessed were mainly in urban areas, and the needs of homeless people in rural areas were not specifically captured. For many residents, we were unable to access NHS data. Many hostel staff referred to this study as ‘dementia’ focused when introducing it to residents, which may have deterred recruitment.

Conclusions

To the best of our knowledge, no other study and no policy acknowledges hostels as ‘dementia communities’ or questions the appropriateness of hostel accommodation for people with dementia. Given the declining number of hostels in England, the limits of NHS engagement with this sector and growing homelessness, this group of people with dementia are under-recognised and excluded from other initiatives.

Future work

A longitudinal study could follow hostel dwellers and outcomes. Ways of improving clinical assessment, record-keeping and treatment could be investigated. A dementia diagnosis could trigger sustained care co-ordination for this vulnerable group.

Sofosbuvir and Ribavirin for Treatment of Chronic Hepatitis C in Patients Coinfected With Hepatitis C Virus and HIV: The Impact on Patient-Reported Outcomes

BACKGROUND

Sofosbuvir-containing regimens have been approved for treatment of hepatitis C virus (HCV) infection in human immunodeficiency virus (HIV)-infected patients. We assessed the effect of treatment with sofosbuvir and ribavirin on patient-reported outcomes (PROs) in individuals with HIV/HCV coinfection.

METHODS

HIV/HCV-coinfected patients were treated for 12 or 24 weeks with sofosbuvir and ribavirin. Matched HCV-monoinfected controls were also evaluated. All subjects completed standard PRO questionnaires before, during, and after treatment.

RESULTS

Included were 497 participants from the PHOTON-1 and PHOTON-2 clinical trials. At baseline, more impairment in PRO scores was noted in HIV/HCV-coinfected patients, compared with HCV-monoinfected patients. During treatment, moderate decrements in PRO scores (change, up to -6.8% on a 0%-100% scale; P = .0053) were experienced regardless of treatment duration and were similar to those for HCV-monoinfected patients (all P > .05). In 413 HIV/HCV-coinfected patients with a virologic response sustained for 12 weeks after treatment cessation, most PRO scores improved (change, up to +7.6%; P < .0001), similar to findings for HCV-monoinfected patients. In multivariate analysis, in addition to clinico-demographic predictors, coinfection with HIV was associated with PRO impairment at baseline (beta, up to -7.6%; P < .002) but not with treatment-emergent changes in PRO scores (all P > .05).

CONCLUSIONS

Patients with HIV/HCV coinfection tolerate interferon-free sofosbuvir-based anti-HCV regimens well and, despite the presence of some baseline impairment, have treatment-emergent changes in PRO scores that are similar to those of patients with HCV monoinfection.

The quality of life of men who have sex with men in China: reliability and validity testing of the SF-36 questionnaire

OBJECTIVE

The aim of the study was to assess the psychometric properties of the 36-Item Short Form Health Survey (SF-36) in the men who have sex with men (MSM) population in China.

METHODS

A cross-sectional survey was conducted among 373 MSM from September to December, 2012, in Zhengzhou and Huludao City, China. Internal reliability of the questionnaire was calculated by Cronbach's α coefficient. Validity was analyzed through construct validity, divisional validity, and collective validity testing.

RESULTS

The overall Cronbach's α coefficient of the SF-36 questionnaire was 0.943, while the Cronbach's α coefficients for each of the dimensions were all > 0.70. Results showed that the SF-36 questionnaire was reliable and valid.

CONCLUSIONS

This study provided evidence that the SF-36 is an acceptable, valid and reliable instrument in evaluating the quality of life of MSM in Mainland China.

Toward meeting the needs of homeless people with schizophrenia: the validity of quality of life measurement

OBJECTIVE

To provide new evidence regarding the suitability of using quality of life (QoL) measurements in homeless people with schizophrenia, we assess the acceptability and psychometric properties of a specific QoL instrument (S-QoL 18) in a population of homeless people with schizophrenia, and we compare their QoL levels with those observed in non-homeless people with schizophrenia.

METHODS

This multi-centre prospective study was conducted in the following 4 French cities: Lille, Marseille, Paris and Toulouse. Two hundred and thirty-six homeless patients with schizophrenia were recruited over a 12 month-period. The S-QoL 18 was tested for construct validity, reliability, external validity and sensitivity to change. The QoL of the 236 homeless patients was compared with 236 French age- and sex-matched non-homeless patients with schizophrenia.

RESULTS

The eight-factor structure of the S-QoL 18 was confirmed by confirmatory factor analysis (RMSEA = 0.035, CFI = 0.95, GFI = 0.99 and SRMR = 0.015). Internal consistency, reliability and sensitivity to change were satisfactory. External validity was confirmed via correlations between S-QoL 18 dimension scores and SF-36, symptomatology and recovery scores. The percentage of missing data did not exceed 5%. Finally, homeless patients had significantly lower QoL levels than non-homeless patients with schizophrenia.

CONCLUSIONS

These results demonstrate the satisfactory acceptability and psychometric properties of the S-QoL 18, suggesting the validity of QoL measurement among homeless patients with schizophrenia. Our study also reported that QoL levels in homeless patients with schizophrenia were dramatically low, highlighting the need for new policies to eradicate homelessness and tackle poverty.

Socio-demographic Profile of Older Adults with HIV/AIDS: Gender and Sexual Orientation Differences

Utilisant des données recueillies par Ontario HIV Treatment Network Cohort Study (OCS), l’objectif principal de cette étude était de décrire les caractéristiques socio-demographiques d’un échantillon de personnes âgées (50 ans et plus) de l’Ontario (n = 1 129) vivant avec le VIH /SIDA. L’objectif secondaire était de comparer quatre sous-echantillons de PVVIH : les femmes (10,6%), les hommes heterosexuels (16,7%), les hommes homosexuels (65,8%), et les hommes bisexuels (6,9%). Ces groupes diffèrent d’une manière significative dans l’âge, l’éducation, le revenu, la nationalité, la race, et le temps passé atteints du VIH. En comparaison à d’autres groupes, les hommes gais et bisexuels (HGB) ont déclaré une stigmatisation plus baisse associée au VIH, et aussi à la stigmatisation sur la divulgation, à la stigmatisation associée à l’image negative de soi, et la stigmatisation associée aux attitudes publiques. HGB ont également signalé une meilleure qualité de vie en ce qui concerne la santé mentale, les scores plus baisses pour la dépression et des scores plus faibles pour l’ inadaptation face à la vie. Ces résultats suggèrent que les services pour les PVVIH plus âgées, y compris la formation sur le VIH pour les prestataires des services pour VIH et les gérontologues, peuvent avoir besoin de répondre aux besoins spécifiques de ces sous-populations.

Food insecurity is associated with greater acute care utilization among HIV-infected homeless and marginally housed individuals in San Francisco

BACKGROUND

Food insecurity, or the uncertain availability of nutritionally adequate, safe foods, has been associated with poor HIV outcomes. There are few data on the extent to which food insecurity impacts patterns of health-care utilization among HIV-infected individuals.

OBJECTIVE

We examined whether food insecurity was associated with hospitalizations, Emergency Department (ED) visits, and non-ED outpatient visits.

METHODS

HIV-infected, homeless and marginally housed individuals participating in the San Francisco Research on Access to Care in the Homeless (REACH) cohort underwent quarterly structured interviews and blood draws. We measured food insecurity with the validated Household Food Insecurity Access Scale, and categorized participants as food secure, mild/moderately food insecure, and severely food insecure. Primary outcomes were: (1) any hospitalizations, (2) any ED visits, and (3) any non-ED outpatient visits. Generalized estimating equations were used to estimate model parameters, adjusting for socio-demographic (age, sex, ethnicity, education, income, housing status, health insurance) and clinical variables (CD4 nadir, time on antiretroviral therapy, depression, and illicit drug use).

RESULTS

Beginning in November 2007, 347 persons were followed for a median of 2 years. Fifty-six percent of participants were food insecure at enrollment. Compared with food-secure persons, those with severe food insecurity had increased odds of hospitalizations [adjusted odds ratio (AOR) = 2.16, 95 % confidence interval (CI) = 1.50-3.09] and ED visits (AOR = 1.71, 95 % CI = 1.06-2.30). While the odds of an outpatient visit were 41 % higher for severely food insecure individuals, the effect was not statistically significant (AOR = 1.41, 95 % CI = 0.99-2.01). Mild/moderate food insecurity was also associated with increased hospitalizations (AOR = 1.56, 95 % CI = 1.06-2.30), ED visits (AOR = 1.57, 95 % CI = 1.22-2.03), and outpatient visits (AOR = 1.68, 95 % CI = 1.20-2.17).

CONCLUSIONS

Food insecurity is associated with increased health services utilization among homeless and marginally housed HIV-infected individuals in San Francisco. Increased ED visits and hospitalizations are not related to fewer ambulatory care visits among food-insecure individuals. Addressing food insecurity should be a critical component of HIV treatment programs and may reduce reliance on acute care utilization.

Labor force participation and health-related quality of life in HIV-positive men who have sex with men: the Multicenter AIDS Cohort Study

Too many people with HIV have left the job market permanently and those with reduced work capacity have been unable to keep their jobs. There is a need to examine the health effects of labor force participation in people with HIV. This study presents longitudinal data from 1,415 HIV-positive men who have sex with men taking part in the Multicenter AIDS Cohort Study. Generalized Estimating Equations show that employment is associated with better physical and mental health quality of life and suggests that there may be an adaptation process to the experience of unemployment. Post hoc analyses also suggest that people who are more physically vulnerable may undergo steeper health declines due to job loss than those who are generally healthier. However, this may also be the result of a selection effect whereby poor physical health contributes to unemployment. Policies that promote labor force participation may not only increase employment rates but also improve the health of people living with HIV.

Relationship between trauma and high-risk behavior among HIV-positive men who do not have sex with men (MDSM)

The incidence of heterosexual HIV transmission continues to increase in the USA. However, little is known about factors that influence high-risk behavior among men who do not have sex with men (MDSM). This study examines the association of childhood sexual abuse and high-risk behaviors among MDSM. The Coping with HIV/AIDS in the Southeast (CHASE) study included 611 HIV-positive individuals in the Southeastern US Bivariate statistics were used to examine the influence of childhood sexual abuse among MDSM, men who have sex with men (MSM), and women. Study findings indicated that among MDSM with HIV, childhood sexual abuse predicted a higher number of sexual partners, alcohol and drug use problems, depression, post-traumatic stress disorder (PTSD), and less trust in medical providers. Similar statistically significant relationships between childhood sexual abuse and negative outcomes were not found for MSM and women with the exception of childhood sexual abuse predicting PTSD and alcohol use in women. Study findings indicate a need for more in-depth research to examine the role of childhood sexual abuse in shaping adult risk behaviors among MDSM as well as a need to assess for and address childhood sexual abuse in this population.

Chronic illness burden and quality of life in an aging HIV population

The population of persons living with HIV (PLWH) is growing older and more prone to developing other chronic health conditions. Disease progression has been shown to be related to quality of life (QoL). However, descriptions of chronic comorbid illnesses and the unique QoL challenges of older adults living with HIV are not well understood and have not been examined in multiple geographic locations. About 452 PLWH aged 50 years or older were recruited from AIDS Service Organizations in nine states. Participants completed a telephone survey that included measures of other chronic health conditions, perceived stress, depression, and health-related quality of life. As much as 94% of the sample reported a chronic health condition in addition to HIV (mode = 2). The highest reported conditions were hypertension, chronic pain, hepatitis, and arthritis. Despite relatively high rates of depression, overall QoL was moderately high for the sample. Physical functioning was most impacted by the addition of other chronic health problems. Social functioning, mental health functioning, stress, and depression were also strongly associated with chronic disease burden. Additional chronic health problems are the norm for PLWH aged 50 years and older. QoL is significantly related to the addition of chronic health problems. As increasing numbers of PLWH reach older age, this raises challenges for providing comprehensive healthcare to older PLWH with multiple chronic conditions.

Access to oral health care and self-reported health status among low-income adults living with HIV/AIDS

OBJECTIVE

We identified factors associated with improved self-reported health status in a sample of people living with HIV/AIDS (PLWHA) following enrollment in oral health care.

METHODS

Data were collected from 1,499 enrollees in the Health Resources and Services Administration HIV/AIDS Bureau's Special Projects of National Significance Innovations in Oral Health Care Initiative. Data were gathered from 2007-2010 through in-person interviews at 14 sites; self-reported health status was measured using the SF-8™ Health Survey's physical and mental health summary scores. Utilization records of oral health-care services provided to enrollees were also obtained. Data were analyzed using general estimating equation linear regression.

RESULTS

Between baseline and follow-up, we found that physical health status improved marginally while mental health status improved to a greater degree. For change in physical health status, a decrease in oral health problems and lack of health insurance were significantly associated with improved health status. Improved mental health status was associated with a decrease in oral health problems at the last available visit and no pain or distress in one's teeth or gums at the last available visit.

CONCLUSION

For low-income PLWHA, engagement in a program to increase access to oral health care was associated with improvement in overall well-being as measured by change in the SF-8 Health Survey. These results contribute to the knowledge base about using the SF-8 to assess the impact of clinical interventions. For public health practitioners working with PLWHA, findings suggest that access to oral health care can help promote well-being for this vulnerable population.

Occurrence and characteristics of chronic pain in a community-based cohort of indigent adults living with HIV infection

Pain is common among people living with HIV/AIDS (PLWHA), but little is known about chronic pain in socioeconomically disadvantaged HIV-infected populations with high rates of substance abuse in the postantiretroviral era. This cross-sectional study describes the occurrence and characteristics of pain in a community-based cohort of 296 indigent PLWHA. Participants completed questionnaires about sociodemographics, substance use, depression, and pain. Cut-point analysis was used to generate categories of pain severity. Of the 270 participants who reported pain or the use of a pain medication in the past week, 8.2% had mild pain, 38.1% had moderate pain, and 53.7% had severe pain. Female sex and less education were associated with more severe pain. Depression was more common among participants with severe pain than among those with mild pain. Increasing pain severity was associated with daily pain and with chronic pain. Over half of the participants reported having a prescription for an opioid analgesic. Findings from this study suggest that chronic pain is a significant problem in this high risk, socioeconomically disadvantaged group of patients with HIV disease and high rates of previous or concurrent use of illicit drugs.

PERSPECTIVE

This article presents epidemiological data showing that unrelieved chronic pain is a significant problem for indigent people living with HIV. Participants reported pain severity similar to those with metastatic cancer. Despite high rates of substance use disorders, approximately half received prescriptions for opioid analgesics, although few for long-acting agents.

Social, structural and behavioral determinants of overall health status in a cohort of homeless and unstably housed HIV-infected men

BACKGROUND

Previous studies indicate multiple influences on the overall health of HIV-infected persons; however, few assess and rank longitudinal changes in social and structural barriers that are disproportionately found in impoverished populations. We empirically ranked factors that longitudinally impact the overall health status of HIV-infected homeless and unstably housed men.

METHODS AND FINDINGS

Between 2002 and 2008, a cohort of 288 HIV+ homeless and unstably housed men was recruited and followed over time. The population was 60% non-Caucasian and the median age was 41 years; 67% of study participants reported recent drug use and 20% reported recent homelessness. At baseline, the median CD4 cell count was 349 cells/µl and 18% of eligible persons (CD4<350) took antiretroviral therapy (ART). Marginal structural models were used to estimate the population-level effects of behavioral, social, and structural factors on overall physical and mental health status (measured by the SF-36), and targeted variable importance (tVIM) was used to empirically rank factors by their influence. After adjusting for confounding, and in order of their influence, the three factors with the strongest negative effects on physical health were unmet subsistence needs, Caucasian race, and no reported source of instrumental support. The three factors with the strongest negative effects on mental health were unmet subsistence needs, not having a close friend/confidant, and drug use. ART adherence >90% ranked 5th for its positive influence on mental health, and viral load ranked 4th for its negative influence on physical health.

CONCLUSIONS

The inability to meet food, hygiene, and housing needs was the most powerful predictor of poor physical and mental health among homeless and unstably housed HIV-infected men in an urban setting. Impoverished persons will not fully benefit from progress in HIV medicine until these barriers are overcome, a situation that is likely to continue fueling the US HIV epidemic.

Population-level effects of uninterrupted health insurance on services use among HIV-positive unstably housed adults

Health services research consistently confirms the benefit of insurance coverage on the use of health services sought in the USA. However, few studies have simultaneously addressed the multitude of competing and unmet needs specifically among unstably housed persons. Moreover, few have accounted for the fact that hospitalization may lead to obtaining insurance coverage, rather than the other way around. This study used marginal structural models to determine the longitudinal impact of insurance coverage on the use of health services and antiretroviral therapy (ART) among HIV-positive unstably housed adults. The impact of insurance status on the use of health services and ART was adjusted for a broad range of confounders specific to this population. Among 330 HIV-positive study participants, both intermittent and continuous insurance coverage during the prior 3-12 months had strong and positive effects on the use of ambulatory care and ART, with stronger associations for continuous insurance coverage. Longer durations of continuous coverage were less robust in affecting emergency and inpatient care. Race and ethnicity had no significant influence on health services use in this low-income population when confounding due to competing needs was considered in adjusted analyses. Given that ambulatory care and ART are factors with substantial potential impact on the course of HIV disease, these data suggest that securing uninterrupted insurance coverage would result in large reductions in morbidity and mortality. Health care policy efforts aimed at increasing consistent insurance coverage in vulnerable populations are warranted.

Basic subsistence needs and overall health among human immunodeficiency virus-infected homeless and unstably housed women

Some gender differences in the progression of human immunodeficiency virus (HIV) infection have been attributed to delayed treatment among women and the social context of poverty. Recent economic difficulties have led to multiple service cuts, highlighting the need to identify factors with the most influence on health in order to prioritize scarce resources. The aim of this study was to empirically rank factors that longitudinally impact the health status of HIV-infected homeless and unstably housed women. Study participants were recruited between 2002 and 2008 from community-based venues in San Francisco, California, and followed over time; marginal structural models and targeted variable importance were used to rank factors by their influence. In adjusted analysis, the factor with the strongest effect on overall mental health was unmet subsistence needs (i.e., food, hygiene, and shelter needs), followed by poor adherence to antiretroviral therapy, not having a close friend, and the use of crack cocaine. Factors with the strongest effects on physical health and gynecologic symptoms followed similar patterns. Within this population, an inability to meet basic subsistence needs has at least as much of an effect on overall health as adherence to antiretroviral therapy, suggesting that advances in HIV medicine will not fully benefit indigent women until their subsistence needs are met.

Quality of life and needs assessment on people living with HIV and AIDS in Malawi

PURPOSE

Malawi is a sub-Saharan African nation with a severe HIV epidemic. The quality of life (QoL) has never been investigated among people living with HIV and AIDS (PLWHA) in Malawi. This study examines the QoL and associated factors including life needs among PLWHA at different stages of their illness in the northern region of Malawi.

METHODS

Survey analysis of consecutive outpatient participants receiving highly active antiretroviral therapy at the Rainbow Clinic and non-HIV patients receiving care at the affiliated Mzuzu Central Hospital during a one-month period was performed. Laboratory testing and clinical diagnosis were used to determine HIV status, determine CD4 count, and classify WHO clinical stage. A total of 267 HIV-infected patients and 598 non-HIV participants completed a needs assessment and a Short Form-36 (SF-36) questionnaire, which contained a QoL subscale. SF-36 subscales and needs assessment scores were analyzed using t-test, ANOVA test, and Generalized Linear Model-Tukey's test.

RESULTS

HIV-positive patients had significantly lower physical functioning (p=0.0365), mental health (p=0.001), social functioning (p<0.0001), and mental component summary (p=0.0069) scores than HIV-negative patients. Further, WHO Stage III HIV patients had significantly lower vitality (p=0.0439) and mental health (p=0.0022) scores than WHO Stages I and II patients; and WHO Stage IV patients had significantly lower vitality (p=0.0015), mental health (p=0.0006), and physical component summary (p=0.0443) scores than WHO Stages I and II patients. Finally, AIDS patients, as determined by CD4 count, had significantly lower bodily pain (p=0.0423) and physical component summary (p=0.0148) scores than non-AIDS, HIV-positive patients.

CONCLUSION

HIV patients undergoing treatment in Malawi have a significantly lower QoL, both mentally and physically, than their non-HIV counterparts. Further, HIV patients at more advanced stages, both by the WHO definition and by CD4 count, have a significantly lower QoL than HIV patients at earlier stages of the disease.

Health and oral health care needs and health care-seeking behavior among homeless injection drug users in San Francisco

Few existing studies have examined health and oral health needs and treatment-seeking behavior among the homeless and injection drug users (IDUs). This paper describes the prevalence and correlates of health and oral health care needs and treatment-seeking behaviors in homeless IDUs recruited in San Francisco, California, from 2003 to 2005 (N = 340). We examined sociodemographic characteristics, drug use patterns, HIV status via oral fluid testing, physical health using the Short Form 12 Physical Component Score, self-reported needs for physical and oral health care, and the self-reported frequency of seeking medical and oral health care. The sample had a lower health status as compared to the general population and reported a frequent need for physical and oral health care. In bivariate analysis, being in methadone treatment was associated with care-seeking behavior. In addition, being enrolled in Medi-Cal, California's state Medicaid program, was associated with greater odds of seeking physical and oral health care. Methamphetamine use was not associated with higher odds of needing oral health care as compared to people who reported using other illicit drugs. Homeless IDUs in San Francisco have a large burden of unmet health and oral health needs. Recent cuts in Medi-Cal's adult dental coverage may result in a greater burden of oral health care which will need to be provided by emergency departments and neighborhood dental clinics.

Food insecurity among homeless and marginally housed individuals living with HIV/AIDS in San Francisco

Food insecurity is a risk factor for both HIV transmission and worse HIV clinical outcomes. We examined the prevalence of and factors associated with food insecurity among homeless and marginally housed HIV-infected individuals in San Francisco recruited from the Research on Access to Care in the Homeless Cohort. We used multiple logistic regression to determine socio-demographic and behavioral factors associated with food insecurity, which was measured using the Household Food Insecurity Access Scale. Among 250 participants, over half (53.6%) were food insecure. Higher odds of food insecurity was associated with being white, low CD4 counts, recent crack use, lack of health insurance, and worse physical and mental health. Food insecurity is highly prevalent among HIV-infected marginally housed individuals in San Francisco, and is associated with poor physical and mental health and poor social functioning. Screening for and addressing food insecurity should be a critical component of HIV prevention and treatment programs.

Measuring pain in the context of homelessness

PURPOSE

The primary objective of this study was to inform the development of measures of pain impact appropriate for all respondents, including homeless individuals, so that they can be used in clinical research and practice. The secondary objective was to increase understanding about the unique experience of homeless people with pain.

METHODS

Seventeen homeless individuals with chronic health conditions (often associated with pain) participated in cognitive interviews to test the functioning of 56 pain measurement items and provided information about their experience living with and accessing treatment for pain.

RESULTS

The most common problems identified with items were that they lacked clarity or were irrelevant in the context of homelessness. Items that were unclear, irrelevant and/or had other identified problems made it difficult for participants to respond. Participants also described multiple ways in which their pain was exacerbated by conditions of homelessness and identified barriers to accessing appropriate treatment.

CONCLUSIONS

Results suggested that the majority of items were problematic for the homeless and require substantial modifications to make the pain impact bank relevant to this population. Additional recommendations include involving homeless in future item bank development, conducting research on the topic of pain and homelessness, and using cognitive interviewing in other types of health disparities research.

Access to primary care for homeless veterans with serious mental illness or substance abuse: a follow-up evaluation of co-located primary care and homeless social services

To examine the hypothesis that a demonstration clinic integrating homeless, primary care, and mental health services for homeless veterans with serious mental illness or substance abuse would improve medical health care access and physical health status. A quasi-experimental design comparing a 'usual VA care' group before the demonstration clinic opened (N = 130) and the 'integrated care' group (N = 130). Regression models indicated that the integrated care group was more rapidly enrolled in primary care, received more prevention services and primary care visits, and fewer emergency department visits, and was not different in inpatient utilization or in physical health status over 18 months. The demonstration clinic improved access to primary care services and reduced emergency services but did not improve perceived physical health status over 18 months. Further research is needed to determine generalizability and longer term effects.

Food insecurity is associated with incomplete HIV RNA suppression among homeless and marginally housed HIV-infected individuals in San Francisco

BACKGROUND AND OBJECTIVES

There is growing international concern that food insecurity may negatively impact antiretroviral (ARV) treatment outcomes, but no studies have directly evaluated the effect of food insecurity on viral load suppression and antiretroviral adherence. We hypothesized that food insecurity would be associated with poor virologic response among homeless and marginally housed HIV-positive ARV-treated patients.

DESIGN

This is a cross-sectional study.

PARTICIPANTS AND SETTING

Participants were ARV-treated homeless and marginally housed persons receiving adherence monitoring with unannounced pill counts in the Research on Access to Care in the Homeless (REACH) Cohort.

MEASUREMENTS

Food insecurity was measured by the Household Food Insecurity Access Scale (HFIAS). The primary outcome was suppression of HIV viral RNA to <50 copies/ml. We used multivariate logistic regression to assess whether food insecurity was associated with viral suppression.

RESULTS

Among 104 participants, 51% were food secure, 24% were mildly or moderately food insecure and 25% were severely food insecure. Severely food insecure participants were less likely to have adherence > or =80%. In adjusted analyses, severe food insecurity was associated with a 77% lower odds of viral suppression (95% CI = 0.06-0.82) when controlling for all covariates. In analyses stratified by adherence level, severe food insecurity was associated with an 85% lower odds of viral suppression (95% CI = 0.02-0.99) among those with < or =80% adherence and a 66% lower odds among those with >80% adherence (95% CI = 0.06-1.81).

CONCLUSIONS

Food insecurity is present in half of the HIV-positive urban poor in San Francisco, one of the best resourced settings for HIV-positive individuals in the United States, and is associated with incomplete viral suppression. These findings suggest that ensuring access to food should be an integral component of public health HIV programs serving impoverished populations.

Improving health status of homeless patients at a nurse-managed clinic in the Midwest USA

Homeless adults have a higher rate of morbidity and mortality than their housed counterparts. Improving the health of homeless adults is a complex problem because of the overlay of individual risk factors, social issues and lack of economic resources. Due to the increased morbidity and mortality rate in homeless adults, it is imperative to develop interventions with demonstrated efficacy that result in improved health outcomes. The purpose of this pre-post pilot study was to compare pre- and post-test scores on specific health outcomes in a group of homeless adults receiving a nurse intervention when utilising a nurse-managed clinic located in the urban core of a Midwestern city in the USA. Between September of 2004 and January 2006, 43 homeless adults completed a health survey at baseline and 2 months later that included measures of health-related quality of life (HRQOL), substance use and health resource use. There was a significant improvement on the post-test scores including substance use, perceived quality and availability of health care, and on two domains of HRQOL: mental health and vitality. This study provides evidence that a nursing intervention can result in improved health outcomes for adult homeless persons.

The role of psychological and behavioral variables in quality of life and the experience of bodily pain among persons living with HIV

With increased life expectancy of individuals living with HIV, quality of life (QOL) has become a focus of treatment. More research is needed to address pain-related QOL and modifiable variables, such as health behaviors, depressive symptoms, and coping styles, which could be included in treatment protocols to improve QOL among individuals with HIV. Objectives of this study were to (1) examine relationships among health behaviors, psychological variables, and QOL, particularly pain-specific QOL, (2) examine the relationships among coping, depressive symptoms, and QOL, and (3) compare QOL scores of individuals with HIV and population-based normative data. HIV positive men and women not currently on highly active antiretroviral therapy were recruited during regular visits to an HIV outpatient clinic. They completed the Medical Outcome Study Health Survey SF-36 scale, which includes a physical components scale, a mental components scale, and a bodily pain subscale. They also completed questionnaires assessing health behaviors, depressive symptoms, and coping styles. Participants (n=97) scored significantly lower on most aspects of QOL than age-matched Canadian and U.S. norms. Hierarchical multiple regressions revealed that physical activity and CD4 cell count were independently related to lower physical components scale scores; smoking and depressive symptoms were independently associated with lower mental components scale scores; and education, physical activity, and depressive symptoms were independently associated with lower pain-related QOL. Depressive symptoms mediated the relationship between coping styles and the mental components scale and pain-related QOL. Results suggest that targeting depressive symptoms, physical activity, and coping strategies as part of comprehensive treatment protocols could help improve pain-specific QOL and overall QOL among individuals with HIV.

Multivitamin supplementation in HIV-positive pregnant women: impact on depression and quality of life in a resource-poor setting

OBJECTIVES

The primary objective of this study was to examine the effect of vitamin supplementation on health-related quality of life and the risk of elevated depressive symptoms comparable to major depressive disorder (MDD) in HIV-positive pregnant women in Dar es Salaam, Tanzania.

METHODS

From April 1995 to July 1997, 1078 HIV-positive pregnant women were enrolled in a randomized controlled trial. We examined the effects of vitamin supplementation on quality of life and the risk of elevated depressive symptoms, assessed longitudinally every 6-12 months.

RESULTS

A substantial prevalence of elevated depressive symptoms (42%) was observed in HIV-positive pregnant women. Multivitamin supplementation (B-complex, C and E) demonstrated a protective effect on depression [relative risk (RR)=0.78; P=0.005] and quality of life [RR=0.72 for social functioning (P=0.001) and vitality (P=0.0001); RR=0.70 for role-physical (P=0.002)]; however, vitamin A showed no effect on these outcomes.

CONCLUSIONS

Multivitamin supplementation (B-complex, C and E) resulted in a reduction in risk of elevated depressive symptoms comparable to MDD and improvement in quality of life in HIV-positive pregnant women in Tanzania.

Quality of life and hostile mentality trend of patients with HIV/AIDS in China

OBJECTIVE

To assess the quality of life (QOL) and hostile mentality trend (HMT) of patients with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in China, and to identify their major concerns.

STUDY DESIGN AND METHODS

Short Form-36 (SF-36) was used to assess QOL, and seven items were developed to assess the HMT. In-depth interviews were conducted with patients and health workers.

RESULTS

SF-36 had moderate reliability, with Cronbach's alpha coefficients ranging from 0.75 to 0.90 and test-retest correlation coefficients ranging from 0.54 to 0.80 for the eight domains. The item-subscale correlation coefficients ranged from 0.46 to 0.97. The QOL of patients with HIV/AIDS was significantly lower than the average QOL of the general population (P<0.01). Hostile mentality of patients was significant (mean scores of the seven items ranged from 2.87 to 4.32, and the mean sum of scores was 3.45 from a range of 1-5). Cronbach's alpha coefficient of HMT items was 0.75 and the test-retest correlation coefficient was 0.80. The major concerns of patients with HIV/AIDS were financial insecurity and family responsibilities, followed by the fear of death and no cure for HIV/AIDS.

CONCLUSION

SF-36 is a reliable instrument for the assessment of QOL of patients with HIV/AIDS. The QOL of patients with HIV/AIDS in China is poor. The HMT is a valuable indicator to monitor the outcomes of care for patients with HIV/AIDS.

The impact of chronic hepatitis C on health-related quality of life in homeless and marginally housed individuals with HIV

Although infection with Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV) frequently co-exist, there has been little research to determine the effects of HIV/HCV co-infection on health-related quality of life (HRQOL). We performed a cross-sectional analysis of baseline data from 216 participants enrolled in a community based study of HIV-infected homeless and marginally housed individuals, using multivariable linear regression analysis to determine if co-infection with HCV was independently associated with lower short-form 36 (SF-36) questionnaire scores. We found that individuals with HCV had significantly lower mean SF-36 scores in the domains of physical functioning, bodily pain, social functioning and role limitation due to emotional health, and that HIV/HCV co-infection was independently associated with a lower physical component score but not a lower mental component score after controlling for numerous covariates. These results suggest that co-infection with HCV may have an adverse effect on HRQOL among homeless and marginally housed individuals with HIV.

Case management is associated with improved antiretroviral adherence and CD4+ cell counts in homeless and marginally housed individuals with HIV infection

BACKGROUND

Case management (CM) coordinates care for persons with complex health care needs. It is not known whether CM is effective at improving biological outcomes among homeless and marginally housed persons with human immunodeficiency virus (HIV) infection. Our goal was to determine whether CM is associated with reduced acute medical care use and improved biological outcomes in homeless and marginally housed persons with HIV infection.

METHODS

We conducted a prospective observational cohort study in a probability-based community sample of HIV-infected homeless and marginally housed adults in San Francisco, California. The primary independent variable was CM, defined as none or rare (any CM in <or=25% of quarters in the study), moderate (>25% but <or=75%), or consistent (>75%). The dependent variables were 3 self-reported health service use measures (receipt of primary care, emergency department visits and hospitalizations, and antiretroviral therapy adherence) and 2 biological measures (increase in CD4(+) cell count of >or=50% and geometric mean HIV load of <or=400 copies/mL).

RESULTS

In multivariate models, CM was not associated with increased primary care, emergency department use, or hospitalization. Moderate CM, compared with no or rare CM, was associated with an adjusted beta coefficient of 0.13 (95% confidence interval [CI], 0.02-0.25) for improved antiretroviral adherence. Consistent CM (adjusted odds ratio [AOR], 10.7; 95% CI, 2.3-49.6) and moderate CM (AOR, 6.5; 95% CI, 1.3-33.0) were both associated with >or=50% improvements in CD4(+) cell count. CM was not associated with geometric HIV load <400 copies/mL when antiretroviral therapy adherence was included in the model. Study limitations include a lack of randomization.

CONCLUSION

CM may be a successful method to improve adherence to antiretroviral therapy and biological outcomes among HIV-infected homeless and marginally housed adults.

Brief report: Factors associated with depression among homeless and marginally housed HIV-infected men in San Francisco

OBJECTIVES

To evaluate the prevalence of and factors associated with depression among HIV-infected homeless and marginally housed men.

DESIGN

Cross-sectional study.

PARTICIPANTS AND SETTING

Homeless and marginally housed men living with HIV in San Francisco identified from the Research on Access to Care in the Homeless (REACH) Cohort.

MEASUREMENTS

The primary outcome was symptoms of depression, as measured by the Beck Depression Inventory (BDI). Multivariate logistic regression was used to identify associations of sociodemographic characteristics, drug and alcohol use, housing status, jail status, having a representative payee, health care utilization, and CD4 T lymphocyte counts.

RESULTS

Among 239 men, 134 (56%) respondents screened positive for depression. Variables associated with depression in multivariate analysis included white race (adjusted odds ratio [AOR]=2.2, confidence interval [CI]=1.3 to 3.9), having a representative payee (AOR=2.4, CI=1.3 to 4.2), heavy alcohol consumption (AOR=4.7, CI=1.3 to 17.1), and recently missed medical appointments (AOR=2.6, CI=1.4 to 4.8).

CONCLUSIONS

Depression is a major comorbidity among the HIV-infected urban poor. Given that missed medical appointments and alcohol use are likely indicators of depression and contributors to continued depression, alternate points of contact are necessary with many homeless individuals. Providers may consider partnering with payees to improve follow-up with individuals who are HIV-positive, homeless, and depressed.
