The HIV pandemic continues to be a global health challenge; 36.9 million persons were estimated to be living with HIV in 2017 . Women account for over half of the adults living with HIV worldwide and up to 60% of persons from low-income and middle-income settings, where health needs are the most pressing [1,2].
Access to healthcare and life-saving antiretroviral therapy (ART) varies greatly across regions and depends on structural and individual factors [1–3]. Access to HIV testing is a prerequisite to ART initiation, but delayed HIV diagnosis and linkage to care are major barriers to timely access to ART, and thus, its clinical benefits [3–6]. Largely a consequence of increases in the uptake of universal HIV screening during pregnancy to prevent mother-to-child HIV transmission over the last decade, women from most geographical regions are diagnosed with HIV earlier and have higher CD4+ cell counts at diagnosis than heterosexually infected men [1,3–6]. These factors underlie some of the reported mortality differences between women and men favoring women [7–11]. However, no study has so far specifically compared early and late mortality differences among women living with HIV (WLWH) across different geographical regions worldwide.
Globally, WLWH differ in their age distribution, HIV transmission routes, socioeconomic status and viral and tuberculosis co-infection rates, and risk factors for non-HIV mortality [1,3–11]. Wide variations exist between countries and regions of the world in terms of access to HIV testing, ART regimens, and CD4+ cell counts at ART initiation, along with HIV testing policies and guidelines for treatment. Many of these factors may be because of healthcare systems and resource availability for healthcare within the individual country. In turn, this may impact mortality rates for WLWH [1,2,12]. Finally, background mortality rates in different regions have striking variations that, together with the previously mentioned aspects, shape the mortality rates of WLWH . Collaboration between large multiregional cohorts from different regions of the world provides an opportunity to describe geographic disparities in mortality. In this work, we estimate all-cause mortality after ART initiation, overall and by duration of ART use, among WLWH in Europe, the Americas and Sub-Saharan Africa up to 48 months after ART initiation, in order to help to understand key underlying drivers of mortality in women from different settings.
Setting and data sources
We merged databases from HIV cohorts in the International Epidemiology Databases to Evaluate AIDS (IeDEA) Collaboration and the Collaboration of Observational HIV Epidemiological Research in Europe (COHERE) in EuroCoord (merger 2015). These collaborations have been described elsewhere [14–19].
IeDEA is an international research consortium that collects HIV/AIDS data through seven international regional centers, four in Africa and one each in the Asia-Pacific region; the Caribbean, Central and South America region; and North America. Five IeDEA regions contributed data to this study: the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) , the Caribbean, Central and South America network for HIV epidemiology (CCASAnet)  and IeDEA East , Southern  and West Africa . COHERE is a collaboration of HIV cohorts across Europe constituting 40 cohorts and cohort collaborations from 34 countries . COHERE includes other collaborations, such as CASCADE  and EuroSIDA .
Institutional review boards approved the pooling of data and their use in collaborative analyses, and ethics permission was granted.
Study population and inclusion criteria
Eligible individuals were ART-naïve women, 18–80 years old at ART initiation, who started their first ART regimen between 1 January 2000 and 31 December 2014. North American participants were required to have a second visit within 12 months of enrollment, regardless of ART initiation status, so that anyone who died soon after enrollment would not have been included in NA-ACCORD. In Southern Africa, analyses were restricted to cohorts from the Republic of South Africa where patient records could be linked to the vital registry. We excluded individuals from the Asia-Pacific region  (N = 849) as the number of deaths was very low, those from Mexico because of having too few eligible participants (N = 100) and those from Argentina (N = 545) as mortality was reported to be under-ascertained and no further corrections could be applied.
Ascertainment of mortality
The primary outcome was death because of any cause in the 48 months after ART initiation. To address concerns regarding death under-ascertainment, a survey addressing ascertainment and matching with external mortality registries was distributed. Seventy-five percent of cohorts in Europe reported good or very good death ascertainment, but only 40% conducted cross-checks with mortality registries. Cumulative mortality in the European cohorts did not vary significantly according to self-assessment of mortality ascertainment (data not shown). Death ascertainment was reported to be poor in East and West Africa. To correct mortality estimates for East Africa, we used an inverse-probability-weighted estimator of the mortality rate where weights are constant and equal to the inverse ratio of the patients who could be traced out of all patients who were lost to follow-up . For corrections of under-ascertainment in West Africa, we used a modification of the approach by Brinkhof et al., which uses inflation factors to account for mortality under-reporting, under the assumption that mortality under-ascertainment was similar in the two regions . Death rates based on observed data were estimated for different participant subgroups. These ‘passive’ mortality estimates were then multiplied by a group-specific inflation factor determined as the ratio of the lost-to-follow-up-adjusted death rates over the observed rates estimated within East African cohorts [21,22]. For the Republic of South Africa cohort, civil identification numbers, wherever available, were cross-checked with national population registers prior to data transfer to confirm dates of death. All sites in the Caribbean, Central and South America region, except for Argentina, reported ascertaining deaths with population-based mortality registries. North American cohorts link to a population-based death registry at least annually.
Data-contributing regions were categorized as Europe; East Africa; West Africa; Southern Africa; South America; North America; and Central America and the Caribbean. The countries in each region are shown in Supplemental Table 1, https://links.lww.com/QAD/B551.
Participant characteristics at ART initiation by region were described using frequency tables for categorical variables and medians and interquartile ranges for continuous variables. Differences in sociodemographic and clinical characteristics by region were assessed with Kruskal–Wallis test for continuous variables and the chi-squared test for independence for categorical variables. We assumed that women from Haiti, Republic of South Africa, West Africa and East Africa with unknown transmission mode were infected through heterosexual contact .
Mortality rates were calculated by region for the intervals 0–3, 3–6, 6–12, 12–24 and 24–48 months after ART initiation. Mortality rate ratios, compared with Europe, were estimated at each interval using a piecewise exponential parametric survival model fit through Poisson regression. The use of a piecewise exponential parametric survival model fit through Poisson regression simplified the prediction of mortality rate ratios for each duration interval on ART, whereas the implicit assumption of constant hazards within each interval produced almost identical inter-regional comparative mortality rate ratio estimates when compared with a piecewise spline-based flexible parametric survival model [23,24]. Parametric survival models offer alternatives and may be more appropriate than semi-parametric techniques, such a Cox regression when the proportional hazards assumption is in question .
Multivariable models were adjusted for baseline age (<30, 30–44, 45–59, ≥60 years), CD4+ cell counts within 6 months prior to ART initiation (0–24, 25–49, 50–99, 100–199, 200–349, ≥350 cells/μl, unknown) and period of ART initiation (2000–2003, 2004–2007, 2008–2011, 2012–2014). As the HIV epidemics in East, West and South Africa, the Caribbean, South and Central America are predominantly heterosexual epidemics, no adjustment for transmission category could be applied for comparisons between these regions and Europe or North America. Neither adjustment for HIV-RNA nor AIDS prior to ART initiation were included because of the high percentage of missing values in these regions. For comparisons between North America and Europe, multivariable models were additionally adjusted for transmission category, HIV-RNA, AIDS at ART initiation, and race/ethnicity in the subset of participants with available information for these variables.
A set of sensitivity analyses were undertaken. Analyses were repeated restricting to patients with documented or presumed heterosexual transmission, patients starting ART post2004, cohorts with more than 50% of data on CD4+ cell counts at baseline and cohorts with ‘very good’ self-reported mortality ascertainment.
Statistical analyses were performed using Stata 14 (StataCorp, College Station, Texas, USA).
A total of 190 175 women (16% Europe, 47% East Africa, 13% West Africa, 19% South Africa, 1% South America, 3% North America and 2% Central America/Caribbean) were included. Median age at ART initiation ranged from 33 years in South Africa to 40 years in North America. The proportion of persons who injected drugs was highest in North America (18%) and Europe (7%). Only 16% of the women in North America were of white race/ethnicity, whereas 63 and 17% were of black race and Hispanic ethnicity, respectively. Race/ethnicity data were available for 45% of European women, 26% of whom were black, largely migrants from sub-Saharan Africa. Of ART initiators, median CD4+ cell counts at initiation were close to 250 cells/μl in Europe and North America, 141 cells/μl in South Africa and 170–190 cells/μl in other regions (Table 1).
In all regions except for North America, because of cohort inclusion criteria in that region, the highest death rates occurred during the first 3 months after starting ART and declined thereafter (Fig. 1). Women from Europe had the lowest death rates across the study period, whereas the highest were observed among women from Central America and the Caribbean between 0 and 3 months, in East Africa between 3 and 6 months and West Africa between 6 and 48 months from ART initiation.
Mortality rates in women from Europe were significantly lower than rates in women from all other regions during the first 48 months after starting ART, except for North American women, whose rates were similar for the first 6 months and significantly higher thereafter (Table 2). The greatest differences were observed in the first 3 months and attenuated thereafter. Taking into account differences in baseline age, CD4+ cell count and period of ART initiation, differences in mortality were attenuated although still of large magnitude and statistically significant. After additional adjustments for transmission category, HIV-RNA and AIDS prior to ART initiation for comparisons between North America and Europe, differences in mortality were reduced, but still present. Further adjustment for race/ethnicity in the subset of patients with available information for this variable contributed to reduction of differences between 6 and 48 months on ART.
Sensitivity analyses yielded results consistent with the main analyses (Supplemental Table 2, https://links.lww.com/QAD/B551).
This large collaborative study found that there was significant variability in all-cause mortality among WLWH in Europe, the Americas and sub-Saharan Africa up to 48 months after ART initiation, with distinct geographical patterns for short-term, midterm and long-term mortality. The highest mortality was observed in WLWH in Central America and the Caribbean and sub-Saharan Africa, who also had the lowest CD4+ cell counts at ART initiation. The lowest mortality was reported in women living in Europe, who had, together with women from North America, the highest CD4+ cell counts; women living in South America had intermediate mortality. These differences were apparent after correcting for under-ascertainment in mortality in most of the African sites. Mortality was highest in the first 3 months after ART initiation in all evaluable regions, and decreased from then onwards to reach stable rates from the first until the fourth year following ART, when inter-regional differences were attenuated.
The baseline differences of WLWH explained some of the relative differences encountered but did not fully explain the higher mortality observed in women from sub-Saharan African and American regions compared with the women on ART living in Europe. Indeed, women from sub-Saharan Africa and from Central America and the Caribbean had the lowest CD4+ cell counts at ART initiation, a strong predictor of subsequent HIV-related, mortality [8–11,26]. Median CD4+ cell counts at ART initiation were close to 250 cells/μl in women living in North America and Europe, but mortality rates differed substantially. The lower mortality of WLWH in Europe compared with women in North America has been previously reported [8,9] and attributed to the accessibility and equity of health services, to background mortality rates, to causes of death of populations affected by HIV in the different settings, and to near complete death ascertainment in North America . Our findings build on these explanations expanding comparisons to East and West Africa, the Caribbean, Central and South and America.
Most of the European countries included in this study have universal healthcare systems, which grant free access to HIV testing, HIV care and ART medications, and this may account for some of the better HIV-related outcomes observed among women in European cohorts. However, not all countries in Europe provide free access to ART for undocumented migrants, a nonnegligible proportion of WLWH in Europe [28,29]. Even for documented migrant women, barriers to access care because of socioeconomic, gender, ethnic and cultural factors exist and may have a negative impact on survival . Barriers to accessing adequate healthcare have been consistently reported in black and Latina women and First Nations/indigenous women in North America, irrespective of HIV status [10,30–33]. In addition, access to HIV testing and life-saving ART among women from low-income and middle-income settings is considerably lower than in Western Europe and North America [1,2,34]. These health inequities may lead to lower CD4+ cell counts at ART initiation, which likely account for the exceedingly high early and overall mortality observed in the women in sub-Saharan Africa and Central and South America and the Caribbean.
Our findings need to be placed in the context of background mortality rates of women from the general population living in geographical regions with generalized HIV epidemics, together with mortality patterns of racial and ethnic minorities in North America and Europe, with concentrated HIV epidemics [1,35,36]. Globally, all-cause mortality in women living in sub-Saharan Africa, the Caribbean, and Central and South America is also higher than among the women from Europe and North America . Within North America, African-American and Latina women have higher mortality rates than white women, both in general [35,36] and from HIV-infection , but patterns have been described to be complex and evolve over time . Conversely, migrant women in Europe have lower all-cause mortality relative to general population women, consistent with healthy migrant selection bias .
For all regions analyzed, and with different magnitudes, mortality was highest in the initial 3 months following ART. The exception to this pattern was North America given NA-ACCORD's inclusion criteria, as anyone who died very soon after enrollment (including those who initiated ART) was excluded, thereby artificially reducing early mortality in North America. Higher mortality soon after ART has been well described and attributed to late ART initiation and is largely caused by AIDS-defining conditions preventable with ART [39–42]. Failures in earlier HIV testing and/or linkage to care to commence ART represent a clear opportunity for intervention. Unfortunately, cause of death was not available in our dataset for most settings, but studies that have analyzed causes of death patterns report that, for both AIDS and non-AIDS defining causes of death, rates are lower in WLWH in Europe than in North America .
These analyses have been performed in the largest and most globally representative sample assembled to date of WLWH. Data from 56 countries in seven multisite cohort collaborations have been harmonized to reach a final sample of nearly 200 000 women initiating ART and under follow-up. Inevitably, selection and information biases were likely to be present, and multiple strategies were used to minimize their effects. Stringent inclusion criteria were required leading to the exclusion of Asia Pacific cohort, Central Africa and some countries within Central and South America [14–19]. Under-ascertainment of mortality at clinical sites in East and West Africa were partially corrected by a modification of Brinkhof and colleagues’ approach [21,22,43,44]. However, under-reporting is likely to be time-sensitive in sites in sub-Saharan Africa and is also likely to increase overtime.
Sensitivity analyses to account for potential selection biases derived from lack of cross-checks with mortality registries in some of the European cohorts, and of differential data availability to characterize losses to follow-up were also performed. Unfortunately, having missing data was inevitable in such an ambitious data collection and harmonization exercise. For example, information on CD4+ cell count and HIV-RNA viral load was missing for a large proportion of the women from lower income settings and reveals the lack of availability of clinical monitoring tools in those regions. Type of ART regimen was not available from all sites, and given that the study period started in 2000, we assumed all the women to be on at least three antiretroviral drugs. Although mortality of women living with HIV in Europe may be under-ascertained, this was assessed through sensitivity analyses that excluded cohorts that did not perform cross-checks with mortality registries and/or reported incomplete or poor death ascertainment, and the main findings did not significantly change. A recent publication highlights that European cohort participants were generally representative of the national HIV-diagnosed population reported by surveillance systems, but that PWID, migrants, persons with low CD4+ cell counts and those over 55 years of age are generally under-represented in European cohorts . Finally, as of today, national ART guidelines have expanded in most settings to ’Treat All’ patients with HIV, regardless of CD4+ cell count or clinical stage, as recommended by WHO in 2015. Although we have controlled for baseline AIDS status and CD4+ cell count, it is possible that differences in ART guidelines between regions, which in part determine who initiates ART, could explain some of the differences observed.
The global health inequalities highlighted in this study pertain to women who have accessed health services and have started ART, so they are likely to underestimate overall gaps for women living with HIV, particularly those not yet diagnosed or linked to care. Voluntary antenatal HIV testing, widely implemented in most countries included in these analyses, has been a major step forward in increasing access to health services, but requires expansion and improvement. The data presented can support the development of context-specific interventions to help countries reach their 2020 targets and improve the life expectancies of HIV-positive women at the global level.
