RESUMEN

BACKGROUND: In sub-Saharan Africa (SSA), integrating HIV testing into antenatal care (ANC) has been crucial toward reducing mother-to-child transmission of HIV. With the introduction of new testing modalities, we explored temporal trends in HIV testing within and outside of ANC and identified sociodemographic determinants of testing during ANC. METHODS: We analyzed data from 139 nationally representative household surveys conducted between 2005 and 2021, including more than 2.2 million women aged 15-49 years in 41 SSA countries. We extracted data on women's recent HIV testing history (<24 months), by modality (ie, at ANC versus outside of ANC) and sociodemographic variables (ie, age, socioeconomic status, education level, number of births, urban/rural). We used Bayesian generalized linear mixed models to estimate HIV testing coverage and the proportion of those that tested as part of ANC. RESULTS: HIV testing coverage (<24 months) increased substantially between 2005 and 2021 from 8% to 38%, with significant variations between countries and subregions. Two percent of women received an HIV test in the 24 months preceding the survey interview as part of ANC in 2005 and 11% in 2021. Among women who received an HIV test in the 24 months preceding the survey, the probability of testing at ANC was significantly greater for multiparous, adolescent girls, rural women, women in the poorest wealth quintile, and women in West and Central Africa. CONCLUSION: ANC testing remains an important component to achieving high levels of HIV testing coverage and benefits otherwise underserved women, which could prove instrumental to progress toward universal knowledge of HIV status in SSA.

RESUMEN

Intimate partner violence (IPV) may increase women's HIV acquisition risk. Still, knowledge on pathways through which IPV exacerbates HIV burden is emerging. We examined the individual and partnership-level characteristics of male perpetrators of physical and/or sexual IPV and considered their implications for women's HIV status. We pooled individual-level data from nationally representative, cross-sectional surveys in 27 countries in Africa (2000-2020) with information on past-year physical and/or sexual IPV and HIV serology among cohabiting couples (≥15 years). Current partners of women experiencing past-year IPV were assumed to be IPV perpetrators. We used Poisson regression, based on Generalized Estimating Equations, to estimate prevalence ratios (PR) for male partner and partnership-level factors associated with perpetration of IPV, and men's HIV status. We used marginal standardization to estimate the adjusted risk differences (aRD) quantifying the incremental effect of IPV on women's risk of living with HIV, beyond the risk from their partners' HIV status. Models were adjusted for survey fixed effects and potential confounders. In the 48 surveys available from 27 countries (N = 111,659 couples), one-fifth of women reported that their partner had perpetrated IPV in the past year. Men who perpetrated IPV were more likely to be living with HIV (aPR = 1.09; 95%CI: 1.01-1.16). The aRD for living with HIV among women aged 15-24 whose partners were HIV seropositive and perpetrated past-year IPV was 30% (95%CI: 26%-35%), compared to women whose partners were HIV seronegative and did not perpetrate IPV. Compared to the same group, aRD among women whose partner was HIV seropositive without perpetrating IPV was 27% (95%CI: 23%-30%). Men who perpetrated IPV are more likely to be living with HIV. IPV is associated with a slight increase in young women's risk of living with HIV beyond the risk of having an HIV seropositive partner, which suggests the mutually reinforcing effects of HIV/IPV.

RESUMEN

BACKGROUND: Achieving the 95-95-95 targets for HIV diagnosis, treatment, and viral load suppression to end the HIV epidemic hinges on eliminating structural inequalities, including intimate partner violence (IPV). Sub-Saharan Africa has among the highest prevalence of IPV and HIV worldwide. We aimed to examine the effects of IPV on recent HIV infection and women's engagement in the HIV care cascade in sub-Saharan Africa. METHODS: We did a retrospective pooled analysis of data from nationally representative, cross-sectional surveys with information on physical or sexual IPV (or both) and HIV testing, from Jan 1, 2000, to Dec 31, 2020. Relevant surveys were identified from data catalogues and previous large-scale reviews, and included the Demographic and Health Survey, the AIDS Indicator Survey, the Population-based HIV Impact Assessment, and the South Africa National HIV Prevalence, Incidence, Behavior and Communication Survey. Individual-level data on all female respondents who were ever-partnered (currently or formerly married or cohabiting) and aged 15 years or older were included. We used Poisson regression to estimate crude and adjusted prevalence ratios (PRs) for the association between past-year experience of physical or sexual IPV (or both), as the primary exposure, and recent HIV infection (measured with recency assays), as the primary outcome. We also assessed associations of past-year IPV with self-reported HIV testing (also in the past year), and antiretroviral therapy (ART) uptake and viral load suppression at the time of surveying. Models were adjusted for participant age, age at sexual debut (HIV recency analysis), urban or rural residency, partnership status, education, and survey-level fixed effects. FINDINGS: 57 surveys with data on self-reported HIV testing and past-year physical or sexual IPV were available from 30 countries, encompassing 280 259 ever-partnered women aged 15-64 years. 59 456 (21·2%) women had experienced physical or sexual IPV in the past year. Six surveys had information on recent HIV infection and seven had data on ART uptake and viral load suppression. The crude PR for recent HIV infection among women who had experienced past-year physical or sexual IPV, versus those who had not, was 3·51 (95% CI 1·64-7·51; n=19 179). The adjusted PR was 3·22 (1·51-6·85). Past-year physical or sexual IPV had minimal effect on self-reported HIV testing in the past year in crude analysis (PR 0·97 [0·96-0·98]; n=274 506) and adjusted analysis (adjusted PR 0·99 [0·98-1·01]). Results were inconclusive for the association of ART uptake with past-year IPV among women living with HIV (crude PR 0·90 [0·85-0·96], adjusted PR 0·96 [0·90-1·02]; n=5629). Women living with HIV who had experienced physical or sexual IPV in the past year were less likely to achieve viral load suppression than those who had not experienced past-year IPV (crude PR 0·85 [0·79-0·91], adjusted PR 0·91 [0·84-0·98], n=5627). INTERPRETATION: Past-year physical or sexual IPV was associated with recent HIV acquisition and less frequent viral load suppression. Preventing IPV is inherently imperative but eliminating IPV could contribute to ending the HIV epidemic.

RESUMEN

BACKGROUND: Measuring recent HIV infections from routine surveillance systems could allow timely and granular monitoring of HIV incidence patterns. We evaluated the relationship of two recent infection indicators with alternative denominators to true incidence patterns. METHODS: We used a mathematical model of HIV testing behaviours, calibrated to population-based surveys and HIV testing services programme data, to estimate the number of recent infections diagnosed annually from 2010 to 2019 in Côte d'Ivoire, Malawi, and Mozambique. We compared two different denominators to interpret recency data: those at risk of HIV acquisition (HIV-negative tests and recent infections) and all people testing HIV positive. Sex and age-specific longitudinal trends in both interpretations were then compared with modelled trends in HIV incidence, testing efforts and HIV positivity among HIV testing services clients. RESULTS: Over 2010-2019, the annual proportion of the eligible population tested increased in all countries, while positivity decreased. The proportion of recent infections among those at risk of HIV acquisition decreased, similar to declines in HIV incidence among adults (≥15 years old). Conversely, the proportion of recent infections among HIV-positive tests increased. The female-to-male ratio of the proportion testing recent among those at risk was closer to 1 than the true incidence sex ratio. CONCLUSION: The proportion of recent infections among those at risk of HIV acquisition is more indicative of HIV incidence than the proportion among HIV-positive tests. However, interpreting the observed patterns as surrogate measures for incidence patterns may still be confounded by different HIV testing rates between population groups or over time.

RESUMEN

BACKGROUND: The DHS wealth index - based on a statistical technique known as principal component analysis - is used extensively in mainstream surveys and epidemiological studies to assign individuals to wealth categories from information collected on common assets and household characteristics. Since its development in the late nineties, the index has established itself as a standard and, due to its ease of use, has led to a large and welcome increase in the analysis of inequalities. The index is, however, known to present some serious limitations, one being a bias towards patterns of urban wealth: the so-called "urban bias". METHODS: We use 10 data sets - 5 MICS (Multiple Indicator Cluster Survey), 4 DHS (Demographic and Health Survey) and one HBS (Household Budget Survey) - to demonstrate that urban bias continues to be a prominent and worrying feature of the wealth index, even after several methodological changes implemented in recent years to try to reduce it. We then propose and investigate an approach to improve the performance of the index and reduce the urban bias. This approach involves the use of ordinal rather than dummy variables, of a polychoric instead of a product-moment correlation matrix, and the use of two principal components rather than one. These approaches are used jointly to produce the polychoric dual-component wealth index (P2C). RESULTS: The P2C index enables a larger proportion of the variance of the asset variables to be accounted for, results in all assets contributing positively to the wealth score, exploits added analytical power from ordinal variables, and incorporates the extra dimension of wealth expressed by the second principal component. It results in a better representation of typically rural characteristics of wealth and leads to the identification of more plausible distributions of both the urban and rural populations across wealth quintiles, which are closer to expenditure quintiles than the standard DHS index. CONCLUSIONS: The P2C wealth index can be easily applied to mainstream surveys, such as the MICS and DHS, and to epidemiological studies; it yields more credible distributions of rural and urban subpopulations across wealth quintiles. It is proposed as an alternative to the DHS wealth index.

RESUMEN

BACKGROUND: Monitoring knowledge of HIV status among people living with HIV is essential for an effective national HIV response. This study estimates progress and gaps in reaching the UNAIDS 2020 target of 90% knowledge of status, and the efficiency of HIV testing services in sub-Saharan Africa, where two thirds of all people living with HIV reside. METHODS: For this modelling study, we used data from 183 population-based surveys (including more than 2·7 million participants) and national HIV testing programme reports (315 country-years) from 40 countries in sub-Saharan Africa as inputs into a mathematical model to examine trends in knowledge of status among people living with HIV, median time from HIV infection to diagnosis, HIV testing positivity, and proportion of new diagnoses among all positive tests, adjusting for retesting. We included data from 2000 to 2019, and projected results to 2020. FINDINGS: Across sub-Saharan Africa, knowledge of status steadily increased from 5·7% (95% credible interval [CrI] 4·6-7·0) in 2000 to 84% (82-86) in 2020. 12 countries and one region, southern Africa, reached the 90% target. In 2020, knowledge of status was lower among men (79%, 95% CrI 76-81) than women (87%, 85-89) across sub-Saharan Africa. People living with HIV aged 15-24 years were the least likely to know their status (65%, 62-69), but the largest gap in terms of absolute numbers was among men aged 35-49 years, with 701 000 (95% CrI 611 000-788 000) remaining undiagnosed. As knowledge of status increased from 2000 to 2020, the median time to diagnosis decreased from 9·6 years (9·1-10) to 2·6 years (1·8-3·5), HIV testing positivity declined from 9·0% (7·7-10) to 2·8% (2·1-3·9), and the proportion of first-time diagnoses among all positive tests dropped from 89% (77-96) to 42% (30-55). INTERPRETATION: On the path towards the next UNAIDS target of 95% diagnostic coverage by 2025, and in a context of declining positivity and yield of first-time diagnoses, disparities in knowledge of status must be addressed. Increasing knowledge of status and treatment coverage among older men could be crucial to reducing HIV incidence among women in sub-Saharan Africa, and by extension, reducing mother-to-child transmission.

RESUMEN

INTRODUCTION: Healthcare systems in Africa suffer from neglect and underfunding, leading to severe challenges across the six World Health Organization (WHO) pillars of healthcare delivery. We conducted this study to identify the principal challenges in the health sector in Africa and their solutions for evidence-based decisions, policy development and program prioritization. METHODS: The study was conducted as part of a recent African Epidemiological Association Meeting in Maputo, Mozambique with participants drawn from 11 African countries, Cuba, Portugal and the United Kingdom. Participants were divided into 10 groups, consisting of 7 to 10 persons each. Brainstorming approaches were used in a structured, modified nominal group process exercise to identify key challenges and strategies to mitigate healthcare service challenges in Africa. Identified challenges and solutions were prioritised by ranking 1-5, with 1 most important and 5 being least important. RESULTS: The first three challenges identified were inadequate human resources (34.29%), inadequate budgetary allocation to health (30%) and poor leadership and management (8.45%). The leading solutions suggested included training and capacity building for health workers (29.69%), increase budgetary allocation to health (20.31%) and advocacy for political support and commitment (12.31%). CONCLUSION: The underdeveloped healthcare systems in Africa need radical solutions with innovative thought to break the current impasse in service delivery. For example, public-private initiatives should be sought, where multinational companies extracting resources from Africa might be encouraged to plough some of the profits back into healthcare for the communities providing the workforce for their commercial activities. Most problems and their solutions lie within human resources, budget allocation and management. These should be accorded the highest priority for better health outcomes.

RESUMEN

HIV testing services (HTS) are a crucial component of national HIV responses. Learning one's HIV diagnosis is the entry point to accessing life-saving antiretroviral treatment and care. Recognizing the critical role of HTS, the Joint United Nations Programme on HIV/AIDS (UNAIDS) launched the 90-90-90 targets stipulating that by 2020, 90% of people living with HIV know their status, 90% of those who know their status receive antiretroviral therapy, and 90% of those on treatment have a suppressed viral load. Countries will need to regularly monitor progress on these three indicators. Estimating the proportion of people living with HIV who know their status (i.e. the 'first 90'), however, is difficult. Methods: We developed a mathematical model (henceforth referred to as 'Shiny90') that formally synthesizes population-based survey and HTS program data to estimate HIV status awareness over time. The proposed model uses country-specific HIV epidemic parameters from the standard UNAIDS Spectrum model to produce outputs that are consistent with other national HIV estimates. Shiny90 provides estimates of HIV testing history, diagnosis rates, and knowledge of HIV status by age and sex. We validate Shiny90 using both in-sample comparisons and out-of-sample predictions using data from three countries: Côte d'Ivoire, Malawi, and Mozambique. Results: In-sample comparisons suggest that Shiny90 can accurately reproduce longitudinal sex-specific trends in HIV testing. Out-of-sample predictions of the fraction of people living with HIV ever tested over a 4-to-6-year time horizon are also in good agreement with empirical survey estimates. Importantly, out-of-sample predictions of HIV knowledge of status are consistent (i.e. within 4% points) with those of the fully calibrated model in the three countries when HTS program data are included. The model's predictions of knowledge of status are higher than available self-reported HIV awareness estimates, however, suggesting - in line with previous studies - that these self-reports could be affected by nondisclosure of HIV status awareness. Conclusion: Knowledge of HIV status is a key indicator to monitor progress, identify bottlenecks, and target HIV responses. Shiny90 can help countries track progress towards their 'first 90' by leveraging surveys of HIV testing behaviors and annual HTS program data.

RESUMEN

BACKGROUND: Mozambique has one of the highest under-5 mortality rates in the world. Community health workers (CHWs) are deployed to increase access to care; in Mozambique they are known as agentes polivalentes elementares (APEs). This study aimed to investigate child deaths in an area served by APEs by analysing the causes, care seeking patterns, and the influence of social capital. METHODS: Caregivers of children under-5 who died in 2015 in Inhambane province, Mozambique, were interviewed using Verbal Autopsy/Social Autopsy (VA/SA) tools with a social capital module. VA data were analysed using the WHO InterVA analytical tool to determine cause of death. SA was analysed using the INDEPTH SA framework for illnesses lasting no more than three weeks. Social capital scores were calculated. RESULTS: 117 child deaths were reported; VA/SA was conducted for 115. Eighty-five had died from an acute illness lasting no more than three weeks, which in most cases could have been treated at community level; 50.6% died from malaria, 11.8% from HIV/AIDS, and 9.4% for each of diarrhoea and acute respiratory infections. In 35.3% the caregiver only noticed that the child was sick when symptoms of very severe illness developed. One in four children were never taken outside the home before dying. Sixteen children were first taken to an APE; of these 7 had signs of very severe illness. Caregivers who waited to seek care until the illness was very severe had a lower social capital score. The mean travel time to go to the APE was 2hrs 50min, which was not different from any other provider. Most received treatment from the APE, 3 were referred. The majority went to another provider after the APE; most to a health centre. CONCLUSIONS: The leading causes of death in children under-5 can be detected, treated or referred by APEs. Major care seeking delays took place in the home, largely due to lack of early disease recognition and late decision-making. Low social capital, distance to APEs and to referral facilities likely contribute to these delays. Increasing caregiver illness awareness is urgently needed, as well as stronger referral linkages. A review of the geographical coverage and scope of work of APEs should be conducted.

RESUMEN

BACKGROUND: The Maternal Mortality Ratio in Mozambique has stagnated at 405 deaths per 100,000 live births with virtually no progress over the last 15 years. Low Institutional Birth Rates (IBRs) levelling around 50% in many rural areas constitute one of the contributing reasons. Demand-side financing has successfully increased usage of maternal health services in other countries, but little information exists on in-kind incentives in rural Africa. The objective was to test the impact on Institutional Birth Rates of giving a USD 5.50 baby package incentive to every woman who came to give birth in a health centre in a rural, poor district of Cabo Delgado, Mozambique. METHODS AND FINDINGS: The intervention was implemented in one district in 2010 with the remaining 15 districts serving as controls. The total population in the 16 districts in 2006 was just under 1.5 million people. IBRs were observed from 2006 to 2013 (53 months before and 55 months after the intervention began). The non-intervention districts showed a slight increase, from a mean IBR of 0.39 (SD = 0.10) in 2006 to 0.67 (SD = 0.13) in 2014. The intervention district had a dramatic increase in IBRs within six months of the start of the intervention in 2010, which was sustained until the end of the study. Adjusting for the background increase and for confounders, including health facilities and health personnel per district, and taking clustering in districts into account, the estimated rate ratio of institutional births in the intervention district was 1.80 (95% CI 1.72, 1.89 p<0.001). CONCLUSION: Women were almost twice as likely to have an institutional birth following the introduction of the baby package.

RESUMEN

BACKGROUND AND AIMS: Mozambique had been ranked among the countries with the highest global incidence of HCC with chronic hepatitis B infection and high exposure to aflatoxin-B1 (AFB1) being major risk factors. Indeed, HCC remains one of the most frequent cancer in Maputo. On the other hand, Mozambique has a high prevalence of infection with Human Immunodeficiency virus (HIV). Our study aims to describe the epidemiology, clinicopathological and serological features of patients with HCC in Maputo Central Hospital and its relationship with HIV. METHODS: A series of 206 patients, diagnosed with HCC via fine needle aspiration, were consecutively included in the study. Patient data was collected using a questionnaire and all patients were tested for HBV, HCV, HIV. RESULTS: Median age was 49 years old and the M: F sex ratio was 2.4. A total of 114 (56.2%) of the patients were HBsAg positive. Hepatitis C antibodies were present in 8.9% of cases, and co-infection with HBV and HCV (HBsAg/anti-HCV) was observed in 4 (2.0%) cases. The remainder, 36.3%, were neither hepatitis B- nor C-related. HIV was detected in 34 cases (18.0%) cases. HIV-HBV or HIV-HCV co-infections were observed in 22 (68.8%) and 2 (6.2%) cases. Overall, positivity for HIV was associated with younger age, and especially in patients with HBsAg+/anti-HCV+. CONCLUSIONS: Our data emphasize the need for a reinforcement of secondary prevention measures in Mozambique. Serological screening for HBV in people born before universal anti-hepatitis B immunization (2001), effective screening, and specific management in HIV(+) patients are urgently needed.

RESUMEN

HIV test-and-treat programmes are being implemented throughout sub-Saharan Africa, enrolling HIV-positive clients into antiretroviral treatment (ART) immediately after diagnosis, regardless of clinical stage or CD4 count. This study conducted in Mozambique examined what influenced clients who tested HIV-positive in the context of test-and-treat to make ART initiation decisions. Eighty in-depth interviews with HIV-positive clients and nine focus group discussions with health care workers were completed across 10 health facilities. 'Good health' acted simultaneously as a barrier and facilitator; clients in good health often found a positive HIV diagnosis hard to cope with since HIV was traditionally associated with ill health. Concerns about ART side effects, fear of inadvertent HIV status disclosure and discrimination, limited privacy at health facilities and long waiting times were also barriers to initiation. In contrast, being in good health also acted as a motivator to start treatment so as to remain healthy, maintain responsibilities such as work and caring for dependents and avoid unwanted disclosure. Study findings offer an in-depth understanding of the complex dynamics between individual perceptions of 'being healthy' and its influence on ART initiation within the context of test-and-treat programme implementation.

RESUMEN

Mozambique had been ranked among the countries with the highest global incidence of HCC with chronic hepatitis B infection and high exposure to aflatoxin-B1 (AFB1) being major risk factors. Indeed, HCC remains one of the most frequent cancer in Maputo. On the other hand, Mozambique has a high prevalence of infection with Human Immunodeficiency virus (HIV). Our study aims to describe the epidemiology, clinicopathological and serological features of patients with HCC in Maputo Central Hospital and its relationship with HIV. A series of 206 patients, diagnosed with HCC via fine needle aspiration, were consecutively included in the study. Patient data was collected using a questionnaire and all patients were tested for HBV, HCV, HIVMedian age was 49 years old and the M: F sex ratio was 2.4. A total of 114 (56.2%) of the patients were HBsAg positive. Hepatitis C antibodies were present in 8.9% of cases, and coinfection with HBV and HCV (HBsAg/anti-HCV) was observed in 4 (2.0%) cases. The remainder, 36.3%, were neither hepatitis B- nor C-related. HIV was detected in 34 cases (18.0%) cases. HIVHBV or HIV-HCV co-infections were observed in 22 (68.8%) and 2 (6.2%) cases. Overall, positivity for HIV was associated with younger age, and especially in patients with HBsAg+/antiHCV+. Our data emphasize the need for a reinforcement of secondary prevention measures in Mozambique. Serological screening for HBV in people born before universal antihepatitis B immunization (2001), effective screening, and specific management in HIV(+) patients are urgently needed.

RESUMEN

BACKGROUND: In mid-2016, Mozambique began phased implementation of the 'Test-and-Treat' policy, which enrolls HIV positive clients into antiretroviral treatment (ART) immediately regardless of CD4 cell count or disease stage. Novel insights into barriers and facilitators to ART initiation among healthy clients are needed to improve implementation of Test and Treat. METHODS AND FINDINGS: A cross-sectional qualitative study was conducted across 10 health facilities in Mozambique. In-depth interviews (IDIs) were conducted with HIV-positive clients (60 who initiated/20 who did not initiate ART within Test and Treat) and 9 focus group discussion (FGDs) were conducted with health care workers (HCWs; n = 53). Data were analyzed using deductive and inductive analysis strategies. Barriers to ART initiation included: (1) feeling 'healthy'; (2) not prepared to start ART for life; (3) concerns about ART side effects; (4) fear of HIV disclosure and discrimination; (5) poor interactions with HCWs; (6) limited privacy at health facilities; and (7) perceptions of long wait times. Facilitators included the motivation to stay healthy and to take care of dependents, as well as new models of ART services such as adaptation of counseling to clients' specific needs, efficient patient flow, and integrated HIV/primary care services. CONCLUSIONS: ART initiation may be difficult for healthy clients in the context of Test-and-Treat. Specific strategies to engage this population are needed. Strategies could include targeted support for clients, community sensitization on the benefits of early ART initiation, client-centered approaches to patient care, and improved efficiency through multi-month scripting and increased workforce.

RESUMEN

The aim was to estimate the prevalence of sexual and physical intimate partner violence (IPV) and its associated factors, in a sample of pregnant women using antenatal care (ANC) in Nampula province - Mozambique. This cross-sectional study was carried out in six health units in Nampula, from February 2013 to January 2014. Overall, 869 participants answered the Conflict Tactics Scale 2. The lifetime and past year prevalence of sexual abuse was 49% and 46%, and of physical abuse was 46% and 44%, respectively. Lifetime and past year sexual abuse was significantly associated with living as a couple, alcohol drinking and having a past diagnosis of gonorrhea. Lifetime and past year physical abuse increased significantly with age and was associated with living as a couple, alcohol drinking and history with syphilis. The prevalence of lifetime and previous year violence among women using ANC was high and similar showing that most women were constantly exposed to IPV. ANC provides a window of opportunity for identifying and acting on violence against women.

RESUMEN

The assessment of pregnant women's knowledge about modes of infections transmission is essential to tailor programs to their needs. This study aimed to assess knowledge about human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) among pregnant women in Nampula - Mozambique, a high-risk area for sexually transmitted infections. At their first antenatal visit, women were invited to participate and data were collected by trained nurses at six public health facilities. Knowledge about HIV transmission modes was high but relevant misconceptions remained. However, knowledge regarding HBV and HCV transmission modes was very limited. There was a significant association between knowledge level and socioeconomic position, making education and women's empowerment key factors in a comprehensive strategy to prevent infections.

RESUMEN

In well-resourced settings, reduced circulating maternal free placental growth factor (PlGF) aids in either predicting or confirming the diagnosis of preeclampsia, fetal growth restriction, stillbirth, preterm birth, and delivery within 14 days of testing when pre-eclampsia is suspected. This operational pilot implementation of maternal plasma PlGF in women with suspected preeclampsia was conducted in six antenatal clinics in Maputo, Mozambique (six control clinics for comparison). The primary outcome was transfer to higher levels of care, following the informative PlGF assay. Of antenatal visits, 133/31,993 (0.42%) and 20/33,841 (0.06%) resulted in pre-eclampsia-related transfers of care for women attending intervention and control clinics, respectively (p < .0001). The clinic-to-delivery for women with low PlGF (<100 pg/ml) interval was shorter, (vs normal PlGF (median 10 days [IQR 1-25] vs 36 [11-83], p < .0001)). Low PlGF was associated with younger maternal age, higher blood pressure, earlier delivery, more therapeutic interventions, preterm birth, lower birth weight, and perinatal loss. In addition, one-third of hypertensive women with PlGF < 50 pg/ml suffered a stillbirth. In urban Mozambican women with symptoms and/or signs suggestive of preeclampsia, low maternal plasma PlGF concentrations are associated with increased risks of adverse pregnancy outcomes, especially early delivery and stillbirth. Therefore, introducing PlGF into the clinical care of women with suspected preeclampsia was associated with increased transfers to higher levels of care; low PlGF (<100 pg/ml) was associated with increased maternal and perinatal risks. PlGF < 50 pg/ml is particularly associated with stillbirth in women with suspected preeclampsia.

RESUMEN

The use of population-based survey data together with sound statistical methods can enhance better estimation of HIV risk factors and explain variations across subgroups of the population. The distribution and determinants of HIV infection in populations must be taken into consideration. We analysed data from the HIV Prevalence and Behaviour Survey in Mozambique aiming to find risk factors associated with HIV infection among Mozambican women. The paper provides a complex survey logistic regression model to explain the variation in HIV seropositivity using demographic, socio-economic and behavioural factors. Results show that women aged 25-29 years, living in female-headed households, living in richer households and those widowed, divorced or not living with a partner have higher odds of being HIV-positive. Findings from our study provide a unique and integrated perspective on risk factors for being HIV-positive among Mozambican women and could support the implementation of programmes aiming to reduce HIV infection in Mozambique.

RESUMEN

OBJECTIVE: To assess the current prevalence, awareness, treatment and control of arterial hypertension in Mozambican population, including adolescents and young adults, and to appraise their trends over the past decade, for the 25-64 years old population. METHODS: A cross-sectional study of a representative sample of the population aged 15-64 years (n = 2965) was conducted in 2014-2015, following the Stepwise Approach to Chronic Disease Risk Factor Surveillance. Data from a survey conducted in 2005 using the same methodological approach was used to assess trends in the age group of 25-64 years. RESULTS: The prevalence of hypertension increased significantly, from 33.1 to 38.9% (P = 0.048), whereas awareness (2005 vs. 2014-2015: 14.8 vs. 14.5%, P = 0.914) and treatment among the aware (2005 vs. 2014-2015: 51.9 vs. 50.1%, P = 0.770) remained similar. Control among the treated increased (from 39.9 to 44.5%, P = 0.587), although not significantly. Mean blood pressure values increased (SBP: from 132.1 to 134.6 mmHg, P = 0.089; DBP: from 78.2 to 82.5 mmHg, P < 0.001). Among participants aged 15-24 years, in 2014-2015 the prevalence of hypertension was 13.1% (95% confidence interval: 9.8-16.4). CONCLUSION: Our findings show that the prevalence of hypertension in Mozambique is among the highest in developing countries, both in adults and adolescents, portraying an ample margin for reduction of the morbidity and mortality burden because of high blood pressure.
