RESUMO
BACKGROUND: Socioeconomic disadvantage is a risk factor for dementia, but longitudinal studies suggest that it does not affect the rate of cognitive decline. Our objective is to understand the manner in which socioeconomic disadvantage shapes dementia risk by examining its associations with midlife cognitive performance and cognitive decline from midlife to old age, including cognitive decline trajectories in those with dementia. METHODS AND FINDINGS: Data are drawn from the Whitehall II study (N = 10,308 at study recruitment in 1985), with cognitive function assessed at 4 waves (1997, 2002, 2007, and 2012). Sociodemographic, behavioural, and cardiometabolic risk factors from 1985 and chronic conditions until the end of follow-up in 2015 (N dementia/total = 320/9,938) allowed the use of inverse probability weighting to take into account data missing because of loss to follow-up between the study recruitment in 1985 and the introduction of cognitive tests to the study in 1997. Generalized estimating equations and Cox regression were used to assess associations of socioeconomic markers (height, education, and midlife occupation categorized as low, intermediate, and high to represent hierarchy in the socioeconomic marker) with cognitive performance, cognitive decline, and dementia (N dementia/total = 195/7,499). In those with dementia, we examined whether retrospective trajectories of cognitive decline (backward timescale) over 18 years prior to diagnosis differed as a function of socioeconomic markers. Socioeconomic disadvantage was associated with poorer cognitive performance (all p < 0.001). Using point estimates for the effect of age, the differences between the high and low socioeconomic groups corresponded to an age effect of 4, 15, and 26 years, for height, education, and midlife occupation, respectively. There was no evidence of faster cognitive decline in socioeconomically disadvantaged groups. Low occupation, but not height or education, was associated with risk of dementia (hazard ratio [HR] = 2.03 [95% confidence interval (CI) 1.23-3.36]) in an analysis adjusted for sociodemographic factors; the excess risk was unchanged after adjustment for cognitive decline but was completely attenuated after adjustment for cognitive performance. In further analyses restricted to those with dementia, retrospective cognitive trajectories over 18 years prior to dementia diagnosis showed faster cognitive decline in the high education (p = 0.006) and occupation (p = 0.001) groups such that large differences in cognitive performance in midlife were attenuated at dementia diagnosis. A major limitation of our study is the use of electronic health records rather than comprehensive dementia ascertainment. CONCLUSIONS: Our results support the passive or threshold cognitive reserve hypothesis, in that high cognitive reserve is associated with lower risk for dementia because of its association with cognitive performance, which provides a buffer against clinical expression of dementia.

The French contribution to global public health over the past two centuries has been marked by a fundamental tension between two approaches: State-provided universal free health care and what we propose to call State humanitarian verticalism. Both approaches have historical roots in French colonialism and have led to successes and failures that continue until the present day. In this paper, the second in The Lancet's Series on France, we look at how this tension has evolved. During the French colonial period (1890s to 1950s), the Indigenous Medical Assistance structure was supposed to bring metropolitan France's model of universal and free public health care to the colonies, and French State imperial humanitarianism crystallised in vertical programmes inspired by Louis Pasteur, while vying with early private humanitarian activism in health represented by Albert Schweitzer. From decolonisation to the end of the Cold War (1960-99), French assistance to newly independent states was affected by sans frontièrisme, Health for All, and the AIDS pandemic. Since 2000, France has had an active role in development of global health initiatives and favoured multilateral action for health assistance. Today, with adoption of the 2030 Sustainable Development Goals and the challenges of non-communicable diseases, economic inequality, and climate change, French international health assistance needs new direction. In the context of current debate over global health as a universal goal, understanding and acknowledging France's history could help strengthen advocacy in favour of universal health coverage and contribute to advancing global equity through income redistribution, from healthy populations to people who are sick and from wealthy individuals to those who are poor.

BACKGROUND: The pediatric antiretroviral (ARV) market is poorly described in the literature, resulting in gaps in understanding treatment access. We analyzed the pediatric ARV market from 2004 to 2012 and assessed pricing trends and associated factors. METHODS: Data on donor funded procurements of pediatric ARV formulations reported to the Global Price Reporting Mechanism database from 2004 to 2012 were analyzed. Outcomes of interest were the volume and mean price per patient-year ARV formulation based on WHO ARV dosing recommendations for a 10 kg child. Factors associated with the price of formulations were assessed using linear regression; potential predictors included: country income classification, geographical region, market segment (originator versus generic ARVs), and number of manufacturers per formulation. All analyses were adjusted for type of formulations (single, dual or triple fixed-dose combinations (FDCs)) RESULTS: Data from 111 countries from 2004 to 2012 were included, with procurement of 33 formulations at a total value of USD 204 million. Use of dual and triple FDC formulations increased substantially over time, but with limited changes in price. Upon multivariate analysis, prices of originator formulations were found to be on average 72 % higher than generics (p < 0.001). A 10 % increase in procurement volume was associated with a 1 % decrease (p < 0.001) in both originator and generic prices. The entry of one additional manufacturer producing a formulation was associated with a decrease in prices of 2 % (p < 0.001) and 8 % (p < 0.001) for originator and generic formulations, respectively. The mean generic ARV price did not differ by country income level. Prices of originator ARVs were 48 % (p < 0.001) and 14 % (p < 0.001) higher in upper-middle income and lower-middle income countries compared to low income countries respectively, with the exception of South Africa, which had lower prices despite being an upper-middle income country. CONCLUSIONS: The donor funded pediatric ARV market as represented by the GPRM database is small, and lacks price competition. It is dominated by generic drugs due to the lower prices offered and the practicality of FDC formulations. This market requires continued donor support and the current initiatives to protect it are important to ensure market viability, especially if new formulations are to be introduced in the future.

The continued scaling-up of antiretroviral therapy (ART) in Sub-Saharan Africa provides an opportunity to further study its impact on sexual behaviors among people living with HIV/AIDS (PLWHA). We explored time trend and correlates of sexual activity among PLWHA initiating ART in Cameroon and compared sexual risk behaviors between patients sexually active before and after initiating ART and those resuming sexual activity after ART initiation. Analyses were based on longitudinal data collected within the randomized trial (n=459) conducted in nine rural district hospitals in Cameroon. Sexual activity was defined as reporting at least one sexual partner during the previous 3 months. Inconsistent condom use (ICU) was defined as reporting to have "never," "sometimes," or "nearly always" used condoms at least once with a partner(s) either HIV-negative or of unknown HIV status during the same period. Mc Nemar tests were used to assess time trend, while mixed-effect logistic regressions were conducted to analyze the effect of time since ART initiation on sexual activity. The proportion of sexually active patients significantly increased over time: from 31.8% at baseline to 40.2 and 47.1% after 6 and 12 months of ART, respectively (p=0.001), to 55.9% after 24 months (p=0.02). After adjustment for behavioral and psychosocial factors, time since ART initiation was independently associated with reporting sexual activity (AOR [95% CI]=1.30 [1.17-1.46] per 6-month increase, p=0.001). ICU was more frequent among patients sexually active both before and after ART initiation than among those who resumed sexual activity after ART initiation (82 vs. 59%, pAssuntos

RESUMO
Despite the remarkable progress in expanding the coverage of social protection mechanisms in health, the Tunisian healthcare system is still largely funded through direct out-of-pocket payments. This paper seeks to assess financial protection in health in the particular policy and epidemiological transition of Tunisia using nationally representative survey data on healthcare expenditure, utilization and morbidity. The extent to which the healthcare system protects people against the financial repercussions of ill-health is assessed using the catastrophic and impoverishing payment approaches. The characteristics associated with the likelihood of vulnerability to catastrophic health expenditure (CHE) are examined using multivariate logistic regression technique. Results revealed that non-negligible proportions of the Tunisian population (ranging from 4.5 % at the conservative 40 % threshold of discretionary nonfood expenditure to 12 % at the 10 % threshold of total expenditure) incurred CHE. In terms of impoverishment, results showed that health expenditure can be held responsible for about 18 % of the rise in the poverty gap. These results appeared to be relatively higher when compared with those obtained for other countries with similar level of development. Nonetheless, although households belonging to richer quintiles reported more illness episodes and received more treatment than the poor households, the latter households were more likely to incur CHE at any threshold. Amongst the correlates of CHE, health insurance coverage was significantly related to CHE regardless of the threshold used. Some implications and policy recommendations, which might also be useful for other similar countries, are advanced to enhance the financial protection capacity of the Tunisian healthcare system.

BACKGROUND: It is well established that high adherence to HIV-infected patients on highly active antiretroviral treatment (HAART) is a major determinant of virological and immunologic success. Furthermore, psychosocial research has identified a wide range of adherence factors including patients' subjective beliefs about the effectiveness of HAART. Current statistical approaches, mainly based on the separate identification either of factors associated with treatment effectiveness or of those associated with adherence, fail to properly explore the true relationship between adherence and treatment effectiveness. Adherence behavior may be influenced not only by perceived benefits-which are usually the focus of related studies-but also by objective treatment benefits reflected in biological outcomes. METHODS: Our objective was to assess the bidirectional relationship between adherence and response to treatment among patients enrolled in the ANRS CO8 APROCO-COPILOTE study. We compared a conventional statistical approach based on the separate estimations of an adherence and an effectiveness equation to an econometric approach using a 2-equation simultaneous system based on the same 2 equations. RESULTS: Our results highlight a reciprocal relationship between adherence and treatment effectiveness. After controlling for endogeneity, adherence was positively associated with treatment effectiveness. Furthermore, CD4 count gain after baseline was found to have a positive significant effect on adherence at each observation period. This immunologic parameter was not significant when the adherence equation was estimated separately. In the 2-equation model, the covariances between disturbances of both equations were found to be significant, thus confirming the statistical appropriacy of studying adherence and treatment effectiveness jointly. CONCLUSIONS: Our results, which suggest that positive biological results arising as a result of high adherence levels, in turn reinforce continued adherence and strengthen the argument that patients who do not experience rapid improvement in their immunologic and clinical statuses after HAART initiation should be prioritized when developing adherence support interventions. Furthermore, they invalidate the hypothesis that HAART leads to "false reassurance" among HIV-infected patients.

OBJECTIVES: To determine the procreational intention rates among cancer survivors whose fertility was unimpaired and to identify the factors associated with their procreational intentions. METHODS: Six thousand nine hundred and fifty-seven adult cancer patients treated between September and October 2002 were randomly selected from the French National Health Insurance Fund's Chronic Disease File. Of the 6957, 4270 responded to a cross-sectional questionnaire 2 years after diagnosis, of whom 959 reported being fertile and responded to a question about their procreational intentions. RESULTS: Among the 257 male and female survivors aged 20-44, 86 (33.5%) had procreational intentions. After adjusting for age, gender, and already having children, only a high educational level (adjusted odds ratio: 3.1, 95% confidence interval 1.3-7.8) and stable or increasing financial resources (2.4, 1.0-5.7) were independently associated with the respondents' procreational intentions. Neither cancer stage at diagnosis nor the present stage significantly affected their plans in this respect. CONCLUSIONS: Two years after cancer diagnosis, the reasons why some survivors who are still fertile have no parenthood projects were similar to those earlier given by members of the general population.

Attempts to establish a health plan for the occupied Palestinian territory were made before the 1993 Oslo Accords. However, the first official national health plan was published in 1994 and aimed to regulate the health sector and integrate the activities of the four main health-care providers: the Palestinian Ministry of Health, Palestinian non-governmental organisations, the UN Relief and Works Agency, and a cautiously developing private sector. However, a decade and a half later, attempts to create an effective, efficient, and equitable system remain unsuccessful. This failure results from arrangements for health care established by the Israeli military government between 1967 and 1994, the nature of the Palestinian National Authority, which has little authority in practice and has been burdened by inefficiency, cronyism, corruption, and the inappropriate priorities repeatedly set to satisfy the preferences of foreign aid donors. Although similar problems exist elsewhere, in the occupied Palestinian territory they are exacerbated and perpetuated under conditions of military occupation. Developmental approaches integrated with responses to emergencies should be advanced to create a more effective, efficient, and equitable health system, but this process would be difficult under military occupation.

Since 2000, the emergence of several large disease-specific global health initiatives (GHIs) has changed the way in which international donors provide assistance for public health. Some critics have claimed that these initiatives burden health systems that are already fragile in countries with few resources, whereas others have asserted that weak health systems prevent progress in meeting disease-specific targets. So far, most of the evidence for this debate has been provided by speculation and anecdotes. We use a review and analysis of existing data, and 15 new studies that were submitted to WHO for the purpose of writing this Report to describe the complex nature of the interplay between country health systems and GHIs. We suggest that this Report provides the most detailed compilation of published and emerging evidence so far, and provides a basis for identification of the ways in which GHIs and health systems can interact to mutually reinforce their effects. On the basis of the findings, we make some general recommendations and identify a series of action points for international partners, governments, and other stakeholders that will help ensure that investments in GHIs and country health systems can fulfil their potential to produce comprehensive and lasting results in disease-specific work, and advance the general public health agenda. The target date for achievement of the health-related Millennium Development Goals is drawing close, and the economic downturn threatens to undermine the improvements in health outcomes that have been achieved in the past few years. If adjustments to the interactions between GHIs and country health systems will improve efficiency, equity, value for money, and outcomes in global public health, then these opportunities should not be missed.

The majority of HIV-infected people in sub-Saharan Africa are women, many of reproductive age. Cameroon is severely hit by the AIDS epidemic and has developed a large national program for improving access to antiretroviral treatment (ART). The reproductive intentions of women living with HIV/AIDS (WLHA) who obtain access to ART in this country remain poorly documented. Our study aimed at exploring factors associated with the desire to have a child among 1433 ART-treated fertile WLHA aged <50. Analyses were based on data collected during the national cross-sectional survey EVAL (ANRS 12-116), which was conducted between September 2006 and March 2007 in 27 HIV care centers in Cameroon. Logistic regression was used to explore factors associated with women's desire to have a child, defined as reporting the wish to have a/another child. A total of 791 women (55%) reported the desire to have a child. After adjusting for age, matrimonial status, number of biological children, and sexual activity, the main factors independently associated with this desire in a multivariate analysis were having a good physical health-related quality of life (1.02 [1.01-1.03] for a one-point increment on the 12-item Short-Form Health Survey scale) and a CD4 count at ART initiation <200 cells/mm(3) (1.7 [1.2-2.4]). As a conclusion, the desire to have a child is frequent among ART-treated WLHA in Cameroon. HIV care and family planning programs should be integrated more thoroughly in order to support WLHA's reproductive choices.

OBJECTIVE: To assess the extent to which user fees for antiretroviral therapy (ART) represent a financial barrier to access to ART among HIV-positive patients in Yaoundé, Cameroon. METHODS: Sociodemographic, economic and clinical data were collected from a random sample of 707 HIV-positive patients followed up in six public hospitals of the capital city (Yaoundé) and its surroundings through face-to-face interviews carried out by trained interviewers independently from medical staff and medical questionnaires filled out by prescribing physicians. Logistic regression models were used to identify factors associated with self-reported financial difficulties in purchasing ART during the previous 3 months. FINDINGS: Of the 532 patients treated with ART at the time of the survey, 20% reported financial difficulty in purchasing their antiretroviral drugs during the previous 3 months. After adjustment for socioeconomic and clinical factors, reports of financial difficulties were significantly associated with lower adherence to ART (odds ratio, OR: 0.24; 95% confidence interval, CI: 0.15-0.40; P < 0.0001) and with lower CD4+ lymphocyte (CD4) counts after 6 months of treatment (OR: 2.14; 95% CI: 1.15-3.96 for CD4 counts < 200 cells/microl; P = 0.04). CONCLUSION: Removing a financial barrier to treatment with ART by eliminating user fees at the point of care delivery, as recommended by WHO, could lead to increased adherence to ART and to improved clinical results. New health financing mechanisms based on the public resources of national governments and international donors are needed to attain universal access to drugs and treatment for HIV infection.

CONTEXT: The national antiretroviral treatment (ART) program in Cameroon has reached one of the highest rate of coverage in Western and Central Africa (58% of the estimated eligible HIV-infected population in June 2008). OBJECTIVES: To assess the extent to which decentralized delivery of HIV care at the district level has contributed to increased access to ART. METHODS: Comparison of ART-treated and non-ART-treated in the sub-sample of medically eligible HIV-positive patients (n=2566) in the cross-sectional ANRS-EVAL survey was carried out among patients seeking HIV care in 14 hospitals at central level (Yaoundé, Douala and capitals of 8 provinces) and 13 at district levels. Logistic regressions and multivariate analysis were carried out to identify factors related to non-access to ART at both levels of care. RESULTS: Only 7% of eligible patients did not have access to ART. After adjustment for time since initial HIV diagnosis and CD4 counts (at initiation of treatment for those ART-treated and at time of survey for those who were not), younger and male patients, as well as those who only had a primary level education were less likely to be ART-treated at central but not at district level, whereas those who were unemployed were less likely to be treated at both levels. Patients were less likely to be treated in central hospitals with higher workload per medical staff member and absence of task shifting policy, and in district hospitals with non-availability of equipment for CD4 counts and larger size (150 beds or more). CONCLUSION: Main persisting barriers in access to ART in Cameroon are rather due to insufficient access to HIV testing and difficulties in patients' referral to ART delivery centers after HIV diagnosis, since the overwhelming majority of eligible patients already seeking HIV care had effective access. However, health systems strengthening (HSS) is still needed to overcome some remaining barriers in access to ART and to guarantee its long-term sustainability.

BACKGROUND: The aim of this study was to assess the cost-effectiveness of HIV treatment alternatives - with and without highly active antiretroviral therapy (HAART) - within alternative strata based on the CD4+ T-cell count at the initiation of treatment in a low-resource setting. METHODS: A retrospective observational study was conducted following 286 HIV-positive individuals admitted to the principal teaching hospital in Casablanca, Morocco, between 1995 and 2002. Patients were stratified by CD4+ T-cell count and regression models were fitted to determine risk of opportunistic infection. Data on healthcare resource use were derived from patient records and were evaluated from the hospital perspective. RESULTS: HAART led to a significant reduction in the number of HIV-related opportunistic infections (P<0.0001), extended survival (61.3 versus 55.2 months; P<0.0001) and reduced hospital stays (P<0.0001) in comparison with care in the absence of HAART. When medical care and drug costs were considered together, HAART was more costly than providing treatment for opportunistic infections. The incremental cost-effectiveness ratio was lower than gross domestic product (GDP) per capita for patients starting HAART with a CD4+ T-cell count <200 cells/mm3, but this increased to nearly three times GDP per capita when HAART was initiated at CD4+ T-cell counts above this threshold. CONCLUSIONS: HAART is more cost-effective than treating HIV-related opportunistic infections and, contrary to conclusions drawn in developed countries, HAART is more cost-effective when the CD4+ T-cell count drops to <200 cells/mm3.

OBJECTIVE: To identify correlates of self-reported antiretroviral therapies (ART) interruptions among people living with HIV and AIDS (PLWHA) in Cameroon. METHODS: Analyses were based on data collected in the national survey EVAL (ANRS 12-116) among 533 ART-treated PLWHA in Yaoundé, the capital city of Cameroon, and its neighbourhood. Logistic regression models were used to identify factors associated with self-reported ART interruptions longer than two consecutive days during the previous 4 weeks. RESULTS: ART interruptions were reported by 68 patients (12.8%). After adjustment for gender, education and household income, characteristics independently associated with interruptions were pharmacy stock shortages [OR (95%CI):3.25 (1.78-5.90)], binge drinking [2.87 (1.39-5.91)] and the number of self-reported slimming symptoms [1.23 (1.02-1.48)]. CONCLUSION: In poor-resource settings where access to second and third-line regimens is still limited, food supply programs and interventions to minimise ART shortage may reduce the risk of ART interruptions.

OBJECTIVE: The aim of this study was to compare the quality of life (QOL) of high-risk breast cancer patients included in a randomized clinical trial (PEGASE 01) comparing conventional chemotherapy versus adding an additional high-dose chemotherapy (HDC) cycle with blood stem cell support. METHODS: A total of 314 patients were included in the clinical trial. QOL evaluations were available for 199 patients. QOL was assessed over a 1-year follow-up period, using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30. The results were analyzed using a linear mixed-effects model. RESULTS: Toxicity of HDC has a strong negative impact on patients' QOL during the treatment phase. This negative impact tended to last longer in the HDC group, as for most of the QLQ-C30 scales, the QOL scores of HDC patients tend to improve at a slower rate than that of patients receiving standard chemotherapy. In particular, physical functioning remains deteriorated 1 year after inclusion for HDC patients comparatively to conventional chemotherapy patients (85.99 vs. 76.65, P = 0.021), and the pain score was still higher in the HDC group at that time (28.32 vs. 15.97, P = 0.004). CONCLUSION: HDC has a negative impact on QOL even after treatment phase. In the absence of an overall survival benefit of using HDC for high-risk breast cancer patients, QOL studies with a longer follow-up play an important role in informing the complex trade-off implied by HDC between higher toxicity, reduced risk of relapse, and QOL decrease after the active phase of treatment.

French national guidelines for the management of HIV non-occupational post-exposure (nPEP) were issued in 1998 and updated in 2003. NPEP is available and free of charge in all emergency or AIDS care units of French hospitals. A regional survey was carried out to study physicians' adherence to national guidelines, and determinants of adherence to nPEP follow-up in individuals sexually exposed to HIV. The survey was based on retrospective data collection of all consultations for nPEP made in the three AIDS information centers in South-Eastern France (January 2001-December 2002). Information included personal data, type of exposure, and treatment at the first visit after exposure and during follow-up. Exposures were classified into high risk (treatment highly recommended), moderate risk (treatment possibly recommended) and negligible risk (treatment never recommended) categories, according to the level of HIV risk of sexual transmission as indicated by the French national nPEP guidelines. Among the 910 sexual exposures, 56%, 37%, and 4% were classified as cases with high, moderate, and no risk respectively. NPEP was prescribed to 85% of cases. HIV risk of sexual exposure was significantly associated with nPEP receipt though more than half of the cases with negligible risk received nPEP. Independent characteristics associated with non-adherence to nPEP follow-up were younger age, being referred to hospital by a physician, sexual exposure with a casual partner or sexual assault, and "moderate risk" exposure. Better information should be provided to physicians prescribing nPEP to limit over-prescription while new strategies should be implemented to improve follow-up of individuals receiving nPEP, especially those who are younger or survivors of sexual assault.

This paper analyzes the redistributive effect and progressivity associated with the current health care financing schemes in the Occupied Palestinian Territory, using data from the first Palestinian Household Health Expenditure Survey conducted in 2004. The paper goes beyond the commonly used "aggregate summary index approach" to apply a more detailed "disaggregate approach". Such an approach is borrowed from the general economic literature on taxation, and examines redistributive and vertical effects over specific parts of the income distribution, using the dominance criterion. In addition, the paper employs a bootstrap method to test for the statistical significance of the inequality measures. While both the aggregate and disaggregate approaches confirm the pro-rich and regressive character of out-of-pocket payments, the aggregate approach does not ascertain the potential progressive feature of any of the available insurance schemes. The disaggregate approach, however, significantly reveals a progressive aspect, for over half of the population, of the government health insurance scheme, and demonstrates that the regressivity of the out-of-pocket payments is most pronounced among the worst-off classes of the population. Recommendations are advanced to improve the performance of the government insurance schemes to enhance its capacity in limiting inequalities in health care financing in the Occupied Palestinian Territory.

Health education can have unexpected effects, sometimes even harmful, in particular when dealing with, on the one hand, multiple risk pathologies and, on the other, one risk factor that is connected to various different pathologies. Certain unexpected effects can be the result of too much information on prevention or when prevention is too focused on one target. In the first scenario, relativity of the information could arise faced with certain health risks or be used against public health objectives. When information is too focused on one target group, it can create discriminatory reactions for the groups at risk, which can translate into denial of the potential risk by those outside of the target group. Other prevention actions can have an unexpected effect, or none at all, because the target behavior is considered functional for the individual. In order to prevent a risk behavior, it is necessary to take into account the threats it is meant to avoid (concurrent risks) and other risk factors meant to attain the same objectives (substitutable risks). In order to understand and avoid different obstacles, people's beliefs and knowledge, which are often rooted in daily behavior and hence difficult to change, must be taken into account. It is also important to situate behavior in context, identifying its function and the concurrent and substitutable risks, which means researching as well the social sciences. In the future, the need for a global health approach will be evident because prevention of risk behaviors increasingly refers to multiple risks in one same pathology as well as concomitant prevention of multiple pathologies.

BACKGROUND: This study aimed to determine factors associated with higher levels of health related quality of life (HRQL) among individuals HIV-infected through drug injection and to evaluate the impact of injecting drug status and opiate substitution treatment (OST) on HRQL. METHODS: Two hundred and forty-three patients, enrolled in the MANIF cohort of patients HIV-infected through IDUs, participated. They completed a self-administered questionnaire, which included an HRQL evaluation (SF-12) and socio-demographic/clinical characteristics at the 42-month visit. Injecting drug status, OST and experience of negative life events (NLE) were collected at any follow-up visit in order to reconstitute individual trajectories. RESULTS: Among the 243 patients, 35% reported a normal mental HRQL and 37% a normal physical HRQL. Independent predictors of "normal" mental HRQL were social support from partner, being a former IDU, no experience of violence-related NLE and few self-reported HAART-related side effects. "Normal" physical HRQL was predicted by younger age, stable partner, being a former IDU (> or = 6 months), CD4 cell count > 500, no experience of financial-related NLE and few HAART self-reported side effects. CONCLUSIONS: As HRQL has been found to have a prognostic value on the survival of HIV patients infected through drug injection, then providing more comprehensive care (for example by paying more attention to patients' experience of stressful events, meeting their needs in psychosocial support and better management of perceived toxicity) could globally improve treatment outcomes in this vulnerable population.
