Longitudinal Assessment of Bone Mineral Density in Women Living With and Without HIV Across Reproductive Phases.

BACKGROUND: Women living with HIV commonly experience low areal bone mineral density (BMD), but whether this is affected by low ovarian hormonal states (prolonged amenorrhea or menopause) is unknown. We compared rates of BMD loss between women living with HIV and HIV-negative control women and investigated its association with low ovarian hormonal states. SETTING: Women living with HIV were enrolled from Vancouver Canada and controls from 9 Canadian sites. METHODS: This longitudinal analysis included age-matched women living with HIV in the Children and Women: AntiRetrovirals and Markers of Aging cohort and controls in the population-based Canadian Multicentre Osteoporosis Study. Rate of change/year in BMD at the total hip and lumbar spine (L1-L4) between 3 and 5 years was compared between groups, adjusting for sociodemographic and clinical variables. RESULTS: Ninety-two women living with HIV (median [interquartile range] age: 49.5 [41.6-54.1] years and body mass index: 24.1 [20.7-30.8] kg/m 2 ) and 278 controls (age: 49.0 [43.0-55.0] years and body mass index: 25.8 [22.9-30.6] kg/m 2 ) were included. Total hip BMD loss was associated with HIV (ß: -0.003 [95% CI: -0.006 to -0.0001] g/cm 2 /yr), menopause (ß: -0.007 [-0.01 to -0.005] g/cm 2 /yr), and smoking (ß: -0.003 [-0.006 to -0.0002] g/cm 2 /yr); BMD gain was linked with higher body mass index (ß: 0.0002 [0.0007-0.0004] g/cm 2 /yr). Menopause was associated with losing L1-L4 BMD (ß: -0.01 [-0.01 to -0.006] g/cm 2 /yr). Amenorrhea was not associated with BMD loss. CONCLUSIONS: HIV and menopause negatively influenced total hip BMD. These data suggest women living with HIV require hip BMD monitoring as they age.

Global Prevalence of Chronic Pain in Women with HIV: A Systematic Review and Meta-analysis.

Chronic pain is common among people with human immunodeficiency virus (HIV) and detrimental to quality of life and overall health. It is often underdiagnosed, undertreated, and frankly dismissed in women with HIV, despite growing evidence that it is highly prevalent in this population. Thus, we conducted a systematic review and meta-analysis to estimate the global prevalence of chronic pain in women with HIV. The full protocol can be found on PROSPERO (identifier CRD42022301145). Of the 2984 references identified in our search, 36 were included in the systematic review and 35 in the meta-analysis. The prevalence of chronic pain was 31.2% (95% confidence interval [CI], 24.6%-38.7%; I2 = 98% [95% CI, 97%-99%]; P < .0001). In this global assessment, we found a high prevalence of chronic pain among women with HIV, underscoring the importance of understanding the etiology of chronic pain, identifying effective treatments, and conducting regular assessments in clinical practice.

Age at Natural Menopause in Women Living with HIV: A Cross-Sectional Study Comparing Self-Reported and Biochemical Data.

Early menopause (<45 years) has significant impacts on bone, cardiovascular, and cognitive health. Several studies have suggested earlier menopause for women living with HIV; however, the current literature is limited by reliance on self-report data. We determined age at menopause in women living with HIV and socio-demographically similar HIV-negative women based on both self-report of menopause status (no menses for ≥12 months) and biochemical confirmation (defined as above plus follicle-stimulating hormone level ≥ 25 IU/mL). Multivariable median regression models assessed factors associated with menopause age, controlling for relevant confounders. Overall, 91 women living with HIV and 98 HIV-negative women were categorized as menopausal by self-report, compared to 83 and 92 by biochemical confirmation. Age at menopause did not differ significantly between groups, whether based on self-report (median [IQR]: 49.0 [45.3 to 53.0] vs. 50.0 [46.0 to 53.0] years; p = 0.28) or biochemical confirmation (50.0 [46.0 to 53.0] vs. 51.0 [46.0 to 53.0] years; p = 0.54). In the multivariable model, no HIV-related or psychosocial variables were associated with earlier age at menopause (all p > 0.05). Overall, HIV status per se was not statistically associated with an earlier age at menopause, emphasizing the importance of comparing socio-demographically similar women in reproductive health and HIV research.

Vitamin D intakes among women living with and without HIV in Canada.

BACKGROUND: Patterns of vitamin D intake are relatively unexplored among women living with HIV, despite its importance for women's health. We compared vitamin D dietary and supplement intakes in women with HIV and population-based national controls and investigated barriers to intake. METHODS: In this case-control study, women with HIV in the Children and Women: AntiRetrovirals and Markers of Aging (CARMA) cohort were matched with Canadian Multicentre Osteoporosis Study (CaMos) controls. Participants were queried for vitamin D in dairy consumption, supplementation/dosage, and sociodemographic variables. We assessed barriers to supplementation and factors associated with dietary intake by regression modelling. RESULTS: Ninety-five women living with HIV were age-matched to 284 controls. Women with HIV had lower income and bone mineral density and were more likely to smoke, take multiple medications and be non-white. Vitamin D dietary intake was lower in women living with HIV versus controls [0.76 vs. 1.79 µg/day; adjusted odds ratio (aOR) for greater than or equal to median intake 0.29 (0.12-0.61), p = 0.002], but any supplementation was higher [62.2% vs. 44.7%; aOR = 3.44 (95% CI: 1.16-11.00), p = 0.03]. Total vitamin D intake was similar between groups. Smoking was associated with no supplementation; non-white ethnicity and low income were related to lower dietary intake. CONCLUSIONS: Women living with HIV showed lower dietary vitamin D intake but higher supplementation rates, suggesting that care providers are promoting supplementation. Women living with HIV who smoke, have low incomes and are non-white may particularly benefit from targeted efforts to improve vitamin D intake.

Factors associated with contraceptive use among women living with HIV in Canada: a controlled, cross-sectional study.

BACKGROUND: Multiple contraindications to combined hormonal contraceptives (CHC) use exist. The impact of these factors on contraceptive choice, particularly among women living with HIV (WLWH), is not well understood. We measured and compared the prevalence of contraceptive use and contraindications among WLWH and women not living with HIV (controls). METHODS: We examined cross-sectional survey and medical chart data from 83 WLWH and 62 controls, aged 16-49 and sexually active, from 2013-2017. We compared the age-adjusted prevalence and types of contraceptives used in the last month and the proportion of women with CHC contraindications, including drug interactions, medical comorbidities, and smoking at ≥ 35 years old. All WLWH received care at an interdisciplinary, women-centred HIV clinic. RESULTS: Compared to controls, WLWH were older (median [IQR)] 39 [34-43] vs 31 [23-41] years; p = 0.003), had less post-secondary education (37% vs 73%; p < 0.001), and more often had household income < $15,000/year (49% vs 30%; p = 0.006). WLWH trended to higher contraceptive prevalence than controls (80% vs 63%; p = 0.06 adjusted for age). Overall hormonal contraceptive use was similar. However, despite controlling for age, WLWH used CHC less (4% vs 18%; p = 0.006) than controls, and had more frequently undergone tubal ligation (12% vs 2%; p = 0.03). WLWH also experienced more CHC contraindications (54% vs 13%; p = 0.0001), including smoking at ≥ 35 years old (30% vs 6%; p = 0.0003) or a CHC-related drug interaction (all antiretroviral related) (25% vs 0%; p = 0.0001). CONCLUSIONS: WLWH attending our interdisciplinary clinic used hormonal contraception at similar rates as controls, though with different types. Differences may reflect different distributions of CHC contraindications. CHC contraindications present barriers to accessing the full range of contraceptive choices for WLWH. Guidelines and education for care providers and WLWH regarding contraceptive choices and drug interactions are needed, especially when care is provided without the benefit of an interdisciplinary women-centered healthcare team.

BACKGROUND: There are many reasons why individuals cannot use combined hormonal contraceptives (CHC). The impact of these reasons on contraceptive choice for women living with HIV (WLWH) are poorly understood. We measured and compared the prevalence of contraceptive choice and factors that may preclude their use in WLWH. METHODS: We examined survey and medical chart data from 83 WLWH and 62 controls (women not living with HIV), aged 16­49 and sexually active, from 2013 to 2017. We compared the prevalence and types of contraceptives used in the last month and the proportion of women with factors that would not allow the use of CHC, including drug interactions, medical conditions, and smoking at ≥ 35 years old. All WLWH received care at a women-centred HIV clinic. RESULTS: Compared to controls, WLWH were older, had less post-secondary education, and more often had household income < $15,000/year. WLWH were more likely to use contraception than controls. Overall hormonal contraceptive use was similar. However, even when accounting for age, WLWH used CHC less than controls, and had more frequently undergone tubal ligation. WLWH also had more reasons that would preclude the use of CHC contraindications including smoking at ≥ 35 years old or a CHC-related drug interaction. CONCLUSIONS: WLWH attending our interdisciplinary clinic used combined hormonal contraception at similar rates as controls, though with different types. Differences may reflect the fact that WLWH more often have factors that do not allow the safe use of CHC. Guidelines and education for care providers and WLWH regarding contraceptive choices and drug interactions are needed.

British Columbia CARMA-CHIWOS Collaboration (BCC3): protocol for a community-collaborative cohort study examining healthy ageing with and for women living with HIV.

INTRODUCTION: Women living with HIV (WLWH) experience accelerated ageing and an increased risk of age-associated diseases earlier in life, compared with women without HIV. This is likely due to a combination of viral factors, gender differences, hormonal imbalance and psychosocial and structural conditions. This interdisciplinary cohort study aims to understand how biological, clinical and sociostructural determinants of health interact to modulate healthy ageing in WLWH. METHODS AND ANALYSIS: The British Columbia Children and Women: AntiRetroviral therapy and Markers of Aging-Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CARMA-CHIWOS) Collaboration (BCC3) study will enrol WLWH (n=350) and sociodemographically matched HIV-negative women (n=350) living in British Columbia. A subset of BCC3 participants will be past participants of CARMA, n≥1000 women and children living with and without HIV, 2008-2018 and/or CHIWOS, n=1422 WLWH, 2013-2018. Over two study visits, we will collect biological specimens for virus serologies, hormones and biological markers as well as administer a survey capturing demographic and sociostructural-behavioural factors. Sociodemographics, comorbidities, number and type of chronic/latent viral infections and hormonal irregularities will be compared between the two groups. Their association with biological markers and psychostructural and sociostructural factors will be investigated through multivariable regression and structural equation modelling. Retrospective longitudinal analyses will be conducted on data from past CARMA/CHIWOS participants. As BCC3 aims to follow participants as they age, this protocol will focus on the first study visits. ETHICS AND DISSEMINATION: This study has been approved by the University of British Columbia Children's and Women's Research Ethics Board (H19-00896). Results will be shared in peer-reviewed journals, conferences and at community events as well as at www.hivhearme.ca and @HIV_HEAR_me. WLWH are involved in study design, survey creation, participant recruitment, data collection and knowledge translation. A Community Advisory Board will advise the research team throughout the study.

Comorbidity and polypharmacy among women living with HIV in British Columbia.

OBJECTIVE: To characterize comorbid disease and medication burden among women living with HIV (WLWH) in British Columbia (BC), Canada. DESIGN: We examined baseline data from 267 WLWH and 276 HIV-negative women, aged at least 19 years, enrolled in the Children and Women: Antiretrovirals and Markers of Aging (CARMA) cohort. METHODS: Self-reported demographic, medical condition, medication, vitamin, and substance exposure data were collected at baseline CARMA study visits. We considered conditions with appropriate concomitant medications to be 'treated'. Wilcoxon rank-sum and Fisher's exact tests compared continuous and categorical variables between WLWH and HIV-negative women. Number of diagnoses, prescribed medications (excluding HIV/antiretrovirals), vitamins, and prevalence of depression/anxiety/panic disorder were compared using negative binomial and logistic regressions for continuous and binary variables, respectively. RESULTS: WLWH were younger [median, interquartile range (IQR) 39.9, 33.6-46.9 vs. 43.6, 31.8-54.6 years; P = 0.01], attained lower education (40.5 vs. 69.6% college/university; P < 0.001), and more often currently smoked tobacco (47.9 vs. 31.9%; P < 0.001) or had income less than $15 000/year (49.0 vs. 43.1%; P < 0.001). Although younger, and despite omitting HIV infection, WLWH had a greater number of diagnoses (incidence rate ratio, 95% confidence interval 1.58, 1.38-1.81; P < 0.001), and more depression/anxiety/panic disorder vs. controls (odds ratio, 95% CI 1.86, 1.22-2.83; P = 0.004). Our model predicts that with mean BMI (26.3), WLWH and HIV-negative peers would have two comorbid diagnoses by age 30 and 60, respectively. CONCLUSIONS: WLWH living in BC have more comorbid illness earlier in life than their HIV-negative peers, and have very high rates of depression/anxiety/panic disorder. Addressing mental health and comorbid conditions is essential to improving health outcomes among WLWH.

Health Care Provider Utilization and Cost of an mHealth Intervention in Vulnerable People Living With HIV in Vancouver, Canada: Prospective Study.

BACKGROUND: Improving adherence to combined antiretroviral therapy (cART) can be challenging, especially among vulnerable populations living with HIV. Even where cART is available free of charge, social determinants of health act as barriers to optimal adherence rates. Patient-centered approaches exploiting mobile phone communications (mHealth) have been shown to improve adherence to cART and promote achievement of suppressed HIV plasma viral loads. However, data are scarce on the health care provider (HCP) time commitments and health care costs associated with such interventions. This knowledge is needed to inform policy and programmatic implementation. OBJECTIVE: The purpose of this study was to approximate the resources required and to provide an estimate of the costs associated with running an mHealth intervention program to improve medication adherence in people living with HIV (PLWH). METHODS: This prospective study of HCP utilization and costs was embedded within a repeated measures effectiveness study of the WelTel short-message service (SMS) mHealth program. The study included 85 vulnerable, nonadherent PLWH in Vancouver, Canada, and resulted in improved medication adherence and HIV plasma viral load among participants. Study participants were provided mobile phones with unlimited texting (where required) and received weekly bidirectional text messages to inquire on their status for one year. A clinic nurse triaged and managed participants' responses, immediately logging all patient interactions by topic, HCP involvement, and time dedicated to addressing issues raised by participants. Interaction costs were determined in Canadian dollars based on HCP type, median salary within our health authority, and their time utilized as part of the intervention. RESULTS: Participant-identified problems within text responses included health-related, social, and logistical issues. Taken together, management of problems required a median of 43 minutes (interquartile range, IQR 17-99) of HCP time per participant per year, for a median yearly cost of Can $36.72 (IQR 15.50-81.60) per participant who responded with at least one problem. The clinic nurse who monitored the texts solved or managed 65% of these issues, and the remaining were referred to a variety of other HCPs. The total intervention costs, including mobile phones, plans, and staffing were a median Can $347.74/highly vulnerable participant per year for all participants or Can $383.18/highly vulnerable participant per year for those who responded with at least one problem. CONCLUSIONS: Bidirectional mHealth programs improve HIV care and treatment outcomes for PLWH. Knowledge about the HCP cost associated, here less than Can $50/year, provides stakeholders and decision makers with information relevant to determining the feasibility and sustainability of mHealth programs in a real-world setting.
