Abstract
A notable rise in health-related disability for which evidence-based rehabilitation is beneficial is evident in low-to-middle income countries. This scoping review aimed to systematically identify and map the most common functioning problems associated with health conditions that contribute most to disability in South Africa using the International Classification of Functioning, Disability and Health (ICF) framework. Peer-reviewed evidence published from January 2006 to December 2021 was systematically searched from five databases. Some 268 studies reporting on functioning problems (impairments, activity limitations, and participation restrictions) in South African adults (>18 years) related to 10 health conditions were included. A total of 130 different functioning problems were mapped to the ICF. The most prevalent problems (top 20) were related to mobility, pain, and mental health but spanned across several ICF domains and were mostly in patients at primary care. The high prevalence and wide range of functioning problems may be particularly burdensome on an already strained primary health care (PHC) system. This points towards targeted planning of innovative strategies towards strengthening rehabilitation service delivery at primary care to address these complexities where there is an inadequate rehabilitation workforce.

Abstract
Background No studies have investigated sex differences in the location and number of pain sites in people living with human immunodeficiency virus (HIV) (PLWH), despite evidence that women, in general, bear a greater burden of pain than men. Aim To determine sex differences in the location and number of pain sites, and whether there were demographic or disease-related differences in the number of pain sites. Setting South African tertiary hospital HIV clinics and a community healthcare centre Methods We conducted a retrospective analysis of records from South African PLWH who had pain. Results Of the 596 participant records, 19% were male (115/596) and the median number of pain sites for both sexes was 2 (interquartile range [IQR]: 1 to 3). Pain was most frequently experienced in the head (men: 12%, women: 38%), feet and ankles (men: 42%, women: 28%), abdomen (men = 19%, women = 28%) and chest (men = 20%, women = 20%). After correcting for multiple comparisons, males were less likely to experience headache than females (Fisher’s exact text, odds ratio [OR] = 0.23, 95% confidence interval [CI]: 0.12 – 0.42, p = 0.000). Pain at other body sites was experienced similarly between the sexes. There was no meaningful variation in the number of pain sites between the sexes (logistic regression, p = 0.157). Conclusion A similar location and number of pain sites were experienced by male and female South African PLWH. The locations of pain sites were different from previous reports, however, suggesting that research into pain in PLWH cannot necessarily be generalised across cultures.

Abstract
Limited information on the prevalence and risk factors for chronic pain is available for developing countries. Therefore, we investigated the prevalence of chronic pain and the association between this pain and various personal and sociodemographic factors by including questions in the South Africa Demographic and Household Survey 2016. The survey was conducted by face-to-face interviews with a nationally representative sample of the adult population (ages 15 and older, n = 10,336). Chronic pain was defined as pain or discomfort that had been experienced all the time or on and off for 3 months or more. The prevalence of chronic pain was 18.3% (95% confidence interval [CI]: 17.0-19.7). Women were more likely than were men to have chronic pain (men = 15.8% [95% CI: 13.9-17.8]; woman = 20.1% [95% CI: 18.4-21.8]), and the prevalence of chronic pain increased from 11.3% (95% CI: 9.6-13.3) for the age range 15 to 24 years to 34.4% (95% CI: 30.6-38.4) for the age range over 65 years. The body sites affected most frequently were the limbs (43.6% [95% CI: 40.4-46.9]), followed by the back (30.5% [95% CI: 27.7-33.6]). This article presents the prevalence of chronic pain in the general population of a middle-income African country. These data give much needed insights into the burden of, and risk factors for, chronic pain in low-resource settings, and identify priority groups for intervention.

Eur J Pain 2020; 25:160-170. [PMID: 32939898 DOI: 10.1002/ejp.1658] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Revised: 09/02/2020] [Accepted: 09/06/2020] [Indexed: 11/08/2022]
Abstract
BACKGROUND People living with HIV (PLWH) frequently experience pain. Following calls to analyse individual-level data in addition to group-level data in pain studies, we compared individual and group-level changes in pain prevalence, intensity and number of pain sites over 48 weeks in a large cohort of PLWH. This is the largest ever cohort study of pain in PLWH, and is the first to report pain at the level of the individual. METHODS Participants included all participants with complete pain records from a randomized clinical trial (RCT) for the treatment of HIV (n = 787/1053). At weeks 0, 12, 24, 36 and 48 we assessed participants' pain in the last week; presence of pain, and if present, the intensity and locations of the pain. We used standard averaging methods to describe data at the group level, and unique graphical reporting methods to analyse data at the level of the individual. RESULTS Group-level data demonstrated a trend for pain prevalence to decline over time (19% week 0, 12% week 48). Worst pain intensity remained stable (median between 4/10 and 5/10), as did the number (median = 1) and common sites of pain across the 48 weeks. In contrast, individual-level data demonstrated high intra-individual variability with regards to the presence of pain, and the intensity and location of the pain. CONCLUSIONS While our group-level data were similar to previous longitudinal studies, an apparent reduction in pain over 48 weeks, the individual-level data showed large variability within individuals in that same time frame. SIGNIFICANCE This graphical analysis highlights the high variability in pain (pain prevalence, intensity and body sites) across time in people living with HIV, and how presenting averaged data hides this important variability. Our data support the reporting of individual-level data in human experimental and observational studies.

Pain in Clients Attending a South African Voluntary Counseling and Testing Center Was Frequent and Extensive But Did Not Depend on HIV Status. J Acquir Immune Defic Syndr 2020; 83:181-188. [PMID: 31929406 DOI: 10.1097/qai.0000000000002248] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/24/2023]
Abstract
BACKGROUND The frequency of pain is reported to be high in people living with HIV, but valid comparisons between people living with HIV and HIV-negative cohorts are rare. We investigated whether HIV infection influenced frequency and characteristics of pain in adults undergoing voluntary testing for HIV. SETTING Participants were recruited from an HIV voluntary counseling and testing center at the Chris Hani Baragwanath Academic Hospital, Soweto, South Africa. METHODS Pain was assessed using the Wisconsin Brief Pain Questionnaire. Depressive and anxiety symptomatology was determined using the Hopkins Symptom checklist-25. We then stratified by HIV status. RESULTS Data from 535 black South Africans were analyzed: HIV-infected n = 70, HIV-uninfected n = 465. Overall, frequency of any current pain was high with 59% [95% confidence interval (CI): 55 to 63, n: 316/535] of participants reporting pain, with no difference related to HIV status: HIV-infected 50% (95% CI: 37 to 61, n: 35/70), HIV-uninfected 60% (95% CI: 56 to 65, n: 281/465). Pain intensity and number of pain sites were similar between the groups as were symptoms of anxiety and depression: mean Hopkins Symptom Checklist-25 1.72 (95% CI: 1.57 to 1.87) HIV-infected participants and 1.68 (95% CI: 1.63 to 1.73) HIV-uninfected participants. Univariate analysis showed female sex and greater depressive and anxiety symptomatology associated with pain. In a multivariable modeling, only depressive and anxiety symptomatology was retained in the model. CONCLUSION The high frequency of pain found in both HIV-infected and HIV-uninfected individuals presenting at a voluntary counseling and testing center was more likely to be associated with depression and anxiety, than with the presence or absence of HIV.

Brain Behav Immun 2018; 69:548-555. [PMID: 29452219 DOI: 10.1016/j.bbi.2018.02.002] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2017] [Revised: 01/12/2018] [Accepted: 02/12/2018] [Indexed: 12/17/2022] Open
Abstract
Poor sleep quality leads to increased immune activation and immune activation leads to worse sleep quality. South African HIV positive patients typically have delayed start of treatment, which has been associated with CD4+ effector T cells being more spontaneously activated in chronically treated patients. This cross-sectional study investigated whether subjective sleep quality was associated with CD4+ T lymphocyte reconstitution in treated South African HIV+ patients. One hundred and thirty-nine treated HIV+ patients (109 F, age average (SD) = 43 (9)) were recruited from Chris Hani Baragwanath Academic Hospital in Soweto, Johannesburg, South Africa. Participants completed questionnaires evaluating their subjective sleep quality (Pittsburgh Sleep Quality Index), daytime sleepiness (Epworth sleepiness scale), pain, and depression severity (Beck Depression Inventory). Univariate and multivariate analyses were run to determine the correlates of sleep quality in this population. Patients had been on antiretroviral treatment for about 4 years and had increased their CD4 counts from a median at baseline of 82 to 467 cells/µL. They had overall poor sleep quality (average (SD) PSQI = 7.7 (±5), 61% reporting PSQI > 5, a marker of lower sleep quality), 41% had clinical depression (average (SD) BDI = 17 (±12)) and 55% reported pain. In two separate multivariate analyses, both the overall CD4 count increase from baseline (p = 0.0006) and higher current CD4 counts (p = 0.0007) were associated with worse sleep quality, when adjusting for depression severity (p < 0.001), daytime sleepiness (p = 0.01) and the presence of pain (p < 0.01). In this cohort of treated South African HIV positive patients, poor sleep quality was associated with higher current CD4 counts, when adjusting for depression severity, daytime sleepiness and pain. Further studies should investigate the temporal relationship between HIV-related poor sleep quality and underlying immune activation.

Abstract
Pain remains highly prevalent in HIV-seropositive (HIV+) patients despite their well-suppressed viremia with combined antiretroviral therapy. Investigating brain abnormalities within the pain matrix, and in relation to pain symptoms, in HIV+ participants may provide objective biomarkers and insights regarding their pain symptoms. We used Patient-Reported Outcome Measurement Information System (PROMIS®) pain questionnaire to evaluate pain symptoms (pain intensity, pain interference and pain behavior), and structural MRI to assess brain morphometry using FreeSurfer (cortical area, cortical thickness and subcortical volumes were evaluated in 12 regions within the pain matrix). Compared to seronegative (SN) controls, HIV+ participants had smaller surface areas in prefrontal pars triangularis (right: p = 0.04, left: p = 0.007) and right anterior cingulate cortex (p = 0.03) and smaller subcortical regions (thalamus: p ≤ 0.003 bilaterally; right putamen: p = 0.01), as well as higher pain scores (pain intensity-p = 0.005; pain interference-p = 0.008; pain-behavior-p = 0.04). Furthermore, higher pain scores were associated with larger cortical areas, thinner cortices and larger subcortical volumes in HIV+ participants; but smaller cortical areas, thicker cortices and smaller subcortical volumes in SN controls (interaction-p = 0.009 to p = 0.04). These group differences in the pain-associated brain abnormalities suggest that HIV+ individuals have abnormal pain responses. Since these abnormal pain-associated brain regions belong to the affective component of the pain matrix, affective symptoms may influence pain perception in HIV+ patients and should be treated along with their physical pain symptoms. Lastly, associations of lower pain scores with better physical or mental health scores, regardless of HIV-serostatus (p < 0.001), suggest adequate pain treatment would lead to better quality of life in all participants.

Abstract
Background Pain is one of the most commonly reported symptoms in people living with HIV/AIDS, whether or not they are receiving anti-retroviral therapy. A recent systematic review identified a paucity of studies exploring pain in women in low and middle income countries. The prevalence and characteristics of pain in women living with HIV/AIDS may differ from that of men as many chronic pain conditions are more prevalent in women. The aims of this study were to establish pain prevalence, characteristics and management in amaXhosa women living with HIV/AIDS. In addition, we aimed to identify whether there were associations between pain in this population and the psychosocial factors of employment, education, self-efficacy, depression, post-traumatic stress disorder, health related quality of life and childhood trauma. Methods A cross-sectional study of 229 women who had undergone HIV testing and were registered patients at a community health centre was conducted. Data were collected by interview with a demographic questionnaire, the Brief Pain Inventory-Xhosa, Childhood Trauma Questionnaire–Xhosa, Harvard Trauma Questionnaire–Xhosa for PTSD, Self-Efficacy for Managing Chronic Disease 6-Item Scale-Xhosa; the EQ-5D health related quality of life instrument, and the Beck Depression Inventory. Results 170 of the women had pain, a prevalence rate of 74.24% (95%CI 68.2 – 79.47%). The women reported significant pain with pain severity of 5.06 ± 1.57 and pain interference of 6.39 ± 1.96 out of 10. Only two women were receiving adequate pain management according to the pain management index. Participants reported a mean of 2.42 ± 1.21 different anatomical sites of pain. There were more unemployed participants in the group with pain and they had significantly fewer years of schooling. Those with pain had lower self-efficacy; health related quality of life and increased depression and PTSD symptom severity. Conclusion This study highlights that pain is a common problem for amaXhosa women living with HIV/AIDS. These data emphasise the need to prioritise pain assessment and management in amaXhosa women living with HIV/AIDS. Routinely assessing for the presence of pain in women with HIV/AIDS has the potential to improve pain management and minimise the impact of pain on function.

Abstract
Chronic pain is common in HIV, but incompletely characterized, including its underlying etiologies, its effect on healthcare utilization, and the characteristics of affected patients in the HIV primary care setting. These data are needed to design and justify appropriate clinic-based pain management services. Using a clinical data warehouse, we analyzed one year of data from 638 patients receiving standard-of-care antiretroviral therapy in a large primary care HIV clinic, located in the Harlem neighborhood of New York City. We found that 40% of patients carried one or more chronic pain diagnoses. The most common diagnoses were degenerative musculoskeletal disorders (eg, degenerative spinal disease and osteoarthritis), followed by neuropathic pain and headache disorders. Many patients (16%) had multiple chronic pain diagnoses. Women, older patients, and patients with greater burdens of medical illness, and psychiatric and substance use comorbidities were disproportionately represented among those with chronic pain diagnoses. Controlling for overall health status, HIV patients with chronic pain had greater healthcare utilization including emergency department visits and radiology procedures. In summary, our study demonstrates the high prevalence of chronic pain disorders in the primary care HIV clinic. Colocated interventions for chronic pain in this setting should not only focus on musculoskeletal pain but also account for complex multifaceted pain syndromes, and address the unique biopsychosocial features of this population. Furthermore, because chronic pain is prevalent in HIV and associated with increased healthcare utilization, developing clinic-based pain management programs could be cost-effective.

Abstract
Pain burden is high in people living with HIV (PLWH), but the effect of this pain on functionality is equivocal. Resilience, the ability to cope with adversity, may promote adaptation to pain, so we hypothesised that higher resilience would correlate with less pain-related impairment of activity. We recruited 197 black South African PLWH, 99 with chronic pain (CP) and 98 patients without. We measured pain intensity and interference using the Brief Pain Inventory, and resilience using the Resilience Scale. Participants were generally highly resilient. Greater resilience correlated with better health-related quality of life, but not with pain intensity or interference. We also measured physical activity objectively, by actigraphy, in a subset of patients (37 with chronic pain and 31 without chronic pain), who wore accelerometers for two weeks. There was no difference in duration or intensity of activity between those with and without pain, and activity was not associated with resilience. In this sample, pain was not associated with altered physical activity. Resilience did not explain differences in pain intensity or pain interference but was associated with improved quality of life. Financial stresses and the fear of HIV stigma may have driven patients to conceal pain and to suppress its expected impairment of activity.

CONTEXT Pain has been reported as the second most commonly reported symptom in people living with HIV/AIDS. In South Africa, there are more than five million people living with HIV/AIDS. Approximately, two million belong to the Xhosa cultural group. The prevalence of pain in amaXhosa living with HIV/AIDS was unknown at the commencement of the study. A culturally appropriate, valid, and reliable instrument is required to measure pain and its impact in this population. OBJECTIVES The objectives of this article are to document the process of translation of the Brief Pain Inventory (BPI) into the BPI-Xhosa and to present the results of the validity and reliability testing of the instrument. METHODS A six-stage forward-backward translation process was followed using bilingual and bicultural translators to ensure decentering of the process. The translated BPI-Xhosa, a demographic questionnaire and the European Quality of Life-5 Dimensions Xhosa version (EQ-5D-Xhosa) health-related quality of life instrument were administered to 229 amaXhosa women living with HIV/AIDS in a resource-poor urban settlement in South Africa. RESULTS A 74.24% (95% CI: 68.2-79.47) prevalence of pain was recorded. The BPI-Xhosa had good concurrent validity when compared with the previously validated EQ-5D-Xhosa. Factor analysis confirmed that the BPI-Xhosa had a two-factor structure (pain severity and pain interference). The instrument had good internal reliability, with Cronbach alphas of 0.77 and 0.83 for the pain severity and pain interference subscales, respectively. CONCLUSION The BPI-Xhosa is a valid instrument which can be used to measure pain prevalence, severity, and interference in amaXhosa women living with HIV/AIDS.

Abstract
OBJECTIVES To evaluate the prevalence, impact, and risk factors for pain among a cohort of human immunodeficiency virus (HIV)-infected adults treated with combination antiretroviral therapy if indicated according to current guidelines. METHODS This was a cross-sectional epidemiological observational study. All patients attending 1 HIV-outpatient center in the United Kingdom in a 10-month period were eligible. Patients completed a validated questionnaire enquiring about demographics, HIV factors, and symptoms of pain. RESULTS Of 1050 eligible participants, 859 (82%) completed a questionnaire. The 1-month period prevalence of pain lasting >1 day was 62.8% among whom 63% reported current pain. The prevalence of pain at most anatomic sites was broadly similar to that observed in population studies using the same questionnaires except that we found considerably higher rates of foot/ankle pain. The median duration of pain was 3 years (range, 0 to 51 y) and the median pain score was 5.0 on an 11-point visual analogue score. Over 40% of people in pain had consulted their primary care physician and >20% were taking analgesics daily. Independent risk factors for current pain were older age (P=0.001), time since diagnosis of HIV infection (P=0.001), and receipt of a protease inhibitor-based regimen (P=0.04). DISCUSSION Pain, and notably foot/ankle pain, is common among adults living with prevalent HIV and is associated with substantial morbidity and health care utilization.

Abstract
OBJECTIVES Opioid use and opioid-related mortality have increased dramatically since the 1990s in North America. The effect of opioids on the liver is incompletely understood. Some studies have suggested that opioids cause liver damage and others have failed to show any harm. HIV/hepatitis C virus (HCV)-coinfected persons may be particularly vulnerable to factors increasing liver fibrosis. We aimed to describe opioid use in an HIV/HCV-coinfected population in Canada and to estimate the association between opioid use and liver fibrosis. METHODS We conducted a cross-sectional descriptive analysis of the Canadian Co-infection Cohort Study data to characterize opioid use. We then conducted a longitudinal analysis to assess the average change in aspartate aminotransferase-to-platelet ratio index (APRI) score associated with opioid use using a generalized estimating equation with linear regression. We assessed the progression to significant liver fibrosis (APRI ≥ 1.5) associated with opioid use with pooled logistic regression. RESULTS In the 6 months preceding cohort entry, 32% of the participants had received an opioid prescription, 28% had used opioids illicitly and 18% had both received a prescription and used opioids illicitly. Neither prescribed nor illicit opioid use was associated with a change in the median APRI score [exp(β) 0.99 (95% confidence interval (CI) 0.82, 1.12) and exp(β) 0.95 (95% CI 0.81, 1.10), respectively] or with faster progression to liver fibrosis [hazard odds ratio (HOR) 1.20 (95% CI 0.73, 1.67) and HOR 1.09 (95% CI 0.63, 1.55), respectively]. CONCLUSIONS Although opioids were commonly used both legally and illegally in our cohort, we were unable to demonstrate a negative impact on liver fibrosis progression.

Abstract
Cross-sectional studies report that pain in ambulatory HIV-infected individuals is frequent and often undermanaged. Expanding access to HIV treatment in developing countries means that infected individuals are living longer, but there is a dearth of pain-directed studies from developing countries that describe the progression of pain and its treatment over any period of time. The aim of this study was to characterize the progression of pain and its treatment over a 6-month period in 92 ambulatory HIV-positive patients attending an outpatient clinic in Johannesburg, South Africa. We used the Wisconsin Brief Pain Questionnaire to assess changes in pain intensity, pain sites, pain interference, and pain treatment. At visit 1, pain was present in 78 of 92 patients (85%). Of the 78 patients with pain, 67 had moderate or severe pain (86%) and pain affected two or more body sites simultaneously in 57 of these patients (73%). After 6 months, pain prevalence still was high, but had fallen to 50 patients (54%). Of the patients with pain at visit 2, the proportion with moderate or severe pain (82%), or two or more pain sites (62%) had decreased. Analgesic use was low at both time points (5% and 25% analgesic use at visit 1 and 2, respectively). Despite the high pain burden, pain interference in daily activities was very low across the period assessed. The burden of pain in this cohort of ambulatory HIV-positive patients was high, but there were significant reductions in pain burden over time.

Abstract
With nearly 1.1 billion inhabitants living in more than 50 countries, Africa is the world's poorest and most socioeconomically underdeveloped continent. Despite some advances for individual states, many African countries have very low opioid consumption and, overall, the continent has the lowest consumption per capita of any in the world. This article presents the findings of the first systematic study of the availability and accessibility of opioids for the management of cancer pain across the continent. Data are reported on the availability and accessibility of opioids for the management of cancer pain in 25 of 52 countries, with 744 million of the region's 1127 million people (66%) covered by the survey. Many countries had severely restricted formularies of opioids and only 15 of 25 had morphine available in oral IR, CR and injectable formulations. Even when opioids are on formulary they are often unavailable, and access is significantly impaired by widespread over-regulation that is pervasive across the region.

Abstract
INTRODUCTION Pain is one of the most commonly reported symptoms in people living with HIV/AIDS (PLWHA). However, wide ranges of pain prevalence have been reported, making it difficult to determine the relative impact of pain in PLWHA. A systematic review of the literature was conducted to establish the prevalence and characteristics of pain and to explore pain management in PLWHA. METHODS Studies that included cross-sectional data were included in the search, which was conducted in April 2012. Databases searched using a time limit of March 1982 to March 2012 included PubMed, Scopus, Africa-wide: NIPAD, CINAHL, PsychARTICLES, PSYCINFO, PSYCHIATRYONLINE, ScienceDirect and Web of Science. Search terms selected were "pain" and "HIV" or "acquired immune deficiency syndrome." Two reviewers independently screened all citation abstracts for inclusion. Methodological quality was evaluated using a standardized 11-item critical appraisal tool. RESULTS After full text review, 61 studies fulfilled the inclusion criteria. Prevalence of pain ranged from a point prevalence of 54% (95%CI 51.14-56.09) to 83% (95%CI 76-88) using a three-month recall period. The reported pain was of moderate-to-severe intensity, and pain was reported in one to two and a half different anatomical sites. Moderate levels of pain interference with function were reported. All nine studies reporting on the adequacy of pain management recorded marked under-treatment of pain. DISCUSSION The studies reviewed reported that pain commonly presents at multiple pain sites with a range of severity suggesting that there are several differing pathological processes contributing to pain at one time. The interplay of variables associated with pain suggests that the biopsychosocial model of pain is an appropriate paradigm from which to view pain in PLWHA and from which to approach the problem, explore causes and establish effective treatment. CONCLUSIONS The results highlight that pain is common in PLWHA at all stages of the disease. The prevalence rates for pain in PLWHA do not appear to have diminished over the 30 years spanning the studies reviewed. The body of work available in the literature thus far, while emphasizing the problem of pain, has not had an impact on its management.

Abstract
BACKGROUND Pain is often inadequately evaluated and treated in sub-Saharan Africa (SSA). OBJECTIVE We sought to assess pain levels and pain treatment in 400 hospitalized patients at a national referral hospital in western Kenya, and to identify factors associated with pain and pain treatment. DESIGN Using face-validated Kiswahili versions of two single-item pain assessment tools, the Numerical Rating Scale (NRS) and the Faces Pain Scale-Revised (FPS-R), we determined patients' pain levels. Additional data collected included patient demographics, prescribed analgesics, and administered analgesics. We calculated mean pain ratings and pain management index (PMI) scores. RESULTS Averaged between the NRS and FPS-R, 80.5% of patients endorsed a nonzero level of pain and 30% of patients reported moderate to severe pain. Older patients, patients with HIV, and cancer patients had higher pain ratings. Sixty-six percent of patients had been prescribed analgesics at some point during their hospitalization, the majority of which were nonopioids. A majority of patients (66%) had undertreated pain (negative scores on the PMI). CONCLUSION This study shows that hospitalized patients in Kenya are experiencing pain and that this pain is often undertreated.

Abstract
CONTEXT Chronic pain remains prevalent in HIV+ adults despite widespread antiretroviral use. Pain continues to be underrecognized and undertreated in this population. In Thailand, similar to the West, HIV care is transitioning toward chronic disease management. Despite the importance of pain management in chronic HIV, the prevalence of pain and adequacy of pain management is unknown in HIV+ adults in Thailand. OBJECTIVES This cross-sectional study aimed to determine the prevalence of chronic pain, the burden of inadequate analgesia, and risk factors for chronic pain in HIV+ adults in Thailand. METHODS A total of 254 HIV+ adults were recruited from an outpatient clinic in Thailand. Interviewers obtained information on demographics, clinical data, and pain characteristics. The burden of inadequate analgesia was assessed using the Brief Pain Inventory. Risk factors were identified with logistic regression analysis. RESULTS Frequent pain was reported by 27% of participants; 22% reported chronic pain. Pain was significantly associated with education less than primary school, a positive depression screen, and the number of years on combined antiretroviral therapy. Eighty-six percent of patients with frequent pain were inadequately treated. Of 34 patients with moderate or severe pain, none received adequate analgesia. Inadequate analgesia was a significant risk factor for poorer quality of life. CONCLUSION Despite widespread antiretroviral use, pain remains common and undertreated in HIV+ adults in Thailand. Undertreated pain negatively impacts quality of life. It is imperative that policy makers and HIV caregivers address this treatment gap to advance the care of people living with HIV in Thailand.
