RESUMEN
Although knowing one's HIV status is a necessary step in initiating antiretroviral treatment, more than a quarter of Burkinabe who are HIV-positive do not know their status. To reach the target of screening at least 95% of people living with HIV (PLHIV), the country has opted for HIV index testing (screening of sexual partners, children and partners of intravenous drug users). This study assessed the knowledge, attitudes and practices of health workers on HIV index testing. A cross-sectional study was conducted among health workers on index testing pilot sites in Burkina Faso. We constructed scores of health workers' knowledge, attitudes and practices regarding HIV index testing. A total of 132 health workers were surveyed, 62.8% of whom were female. Regarding profiles, 44.7% of the participants were nurses and 5.3% were midwives; physicians and psychosocial counselors accounted for 16.7 and 33.3%, respectively. Most of the participants worked in public health centers (60.6%). Overall, the majority of the participants had poor or average knowledge (85.6%) of the index testing strategy and harmful or inadequate practices (87.1%). Less than half (40.9%) had favorable attitudes toward the strategy. Our study showed that the knowledge of health workers was generally average, their attitudes were not very favorable and their practices were mostly inadequate with regard to HIV index testing. In order to increase the chances of reaching the first 95% of UNAIDS, trainings on the topic must be designed for health workers.
RESUMEN
People living with HIV (PLHIV) satisfaction regarding to care could play an important role in the elimination of HIV epidemic by 2030. We assessed Burkina Faso PLHIV satisfaction regarding to their care, and identified its associated factors. A representative nationwide cross-sectional study was performed in 2021-2022 in 30 HIV/AIDS care sites. PLHIV aged at least 18 years, receiving ART for six months or plus were included. Individual and structural data were collected using a questionnaire administered by trained investigators. Satisfaction with HIV/AIDS care was explored using six components (reception, waiting time to medical visit, care environment, sharing updated information on HIV AIDS, answering to PLHIV questions, and providing tailored care and advice to PLHIV needs). Factors associated with satisfaction were identified using logistic regressions. 448 PLHIV were considered in this analysis. Median age was 46 years. Overall satisfaction regarding to care was 40,8% (95% confidence interval 95% CI 36.2-45.6). Specifically, it was 90.6, 54.9, 85.3, 75.7, 90.8, and 93.3% regarding to reception, waiting time, care environment, sharing updated information, answering to PLHIV questions, and providing tailored care and advice to PLHIV needs, respectively. Attending to medical visits in community-based organization (CBO) and private clinics (adjusted odds ratio aOR 1.82, 95% CI 1.14-2.93, P#x003C;0.001), as well as in tertiary hospitals (aOR 2.37, 95% CI 1.45-3.87, P=0.001) were positively associated with PLHIV satisfaction. Burkina Faso PLHIV are generally unsatisfied with care. HIV national authorities should promote HIV care in CBO clinics model in the delivery of HIV services in others public sites.
RESUMEN
Introduction: Approximately a quarter of people living with HIV (PLHIV) had their plasma viral load (PVL) measured in 2020 in Burkina Faso. The purpose of this study was to assess the knowledge, attitudes, and practices (KAP) of health workers regarding HIV PVL measurement. Methods: A cross-sectional study was conducted among health workers involved in the care of PLHIV in the 13 regions of Burkina Faso in 2021. Scores were constructed to assess their KAP on PVL measurement. Factors associated with knowledge and practices were identified by logistic regression. Results: A total of 255 health workers were surveyed. The majority had good knowledge (73%) and favorable attitudes (93%). However, 40% had inadequate practices. Taking into account the availability of a laboratory to carry out PVL tests within the health center, having a coordinating role increased the likelihood of having good knowledge, while not having a medical qualification reduced this likelihood. Good practices were more common among health workers working at the second level of the health pyramid. Conclusions: Interventions to increase the demand for a measurement of PVL are essential to improve the care of PLHIV. For example, future investigations could explore the role of mediators in increasing the demand for PVL among PLHIV and their caregivers.
Introduction: Environ un quart des personnes vivant avec le virus de l'immunodéficience humaine (PVVIH) avait réalisé une charge virale plasmatique (CVP) en 2020 au Burkina Faso. Le but de cette étude était d'évaluer les connaissances, les attitudes et les pratiques (CAP) des agents de santé en matière de mesure de la CVP du VIH. Méthodes: Une étude transversale a été conduite auprès des agents de santé impliqués dans la prise en charge des PVVIH dans les 13 régions du Burkina Faso en 2021. Des scores ont été construits pour évaluer leurs CAP sur la mesure de la CVP. Les facteurs associés aux connaissances et pratiques ont été identifiés par une régression logistique. Résultats: Au total, 255 agents de santé ont été inclus dans l'étude. La majorité avait de bonnes connaissances (73 %) et des attitudes favorables (93 %). Cependant, 40 % avaient des pratiques inadéquates. Tenant compte de la disponibilité d'un laboratoire de réalisation de la CVP au sein du centre de santé, occuper un rôle de coordonnateur augmentait la probabilité d'avoir de bonnes connaissances, tandis que ne pas avoir une qualification médicale réduisait cette probabilité. Les bonnes pratiques étaient plus courantes chez les agents santé travaillant au deuxième niveau de la pyramide sanitaire. Conclusions: Des interventions pour accroître la réalisation de la CVP sont indispensables pour améliorer la prise en charge des PVVIH. Par exemple, des investigations futures pourraient étudier le rôle des médiateurs dans l'accroissement de la demande de la CVP auprès des PVIHH et de leur soignant.

Résumé:l'utilisation des antirétroviraux (ARV) à grande échelle aux personnes vivant avec le VIH (PVVIH) s'accompagne d'un développement de résistance au VIH (R-ARV). Nous avons déterminé la performance de trois indicateurs d'alerte précoce (IAP) associés à un risque élevé d'émergence de R-ARV au Burkina Faso à travers une étude transversale répétée entre 2014 et 2017. Nous avons analysé l'évolution des IAP de l'émergence de R-ARVau cours de cette période. Il s'agissait de l'IAP1 (Retrait des ARV dans les délais),l'IAP2 (Rétention sous traitement ARV «TARV¼ à 12 mois) et de l'IAP4 (pratiques de prescription des ARV).Au total, 27 sites ont été évalués. La médiane des patients qui ont retiré le TARV dans les délais était respectivement de 61% en 2015, 60% en 2016 et à 58% en 2017. Aucun site n Ìa atteint le seuil d'au moins 95% dans les cohortes de 2014 et 2015. Les médianes de la rétention sous TARV à 12 mois pour les cohortes de 2014, 2015 et 2016 ont été de 70%, 69% et 65% respectivement. Le seuil de rétention dans le TARV à 12 mois d'au moins 85% n'a été atteint que dans deux sites. Même si la prescription des ARV est conforme aux directives nationales, la qualité des soins offerts aux PVVIH a régressé de 2014 à 2017 avec un risque élevé d'émergence de R-ARV. Pour minimiser ce risque, l'éducation thérapeutique des patients et le système de recherche des perdus de vue doivent être renforcés.
The widespread use of antiretrovirals (ARVs) to people living with HIV (PLHIV) is accompanied by the development of HIV resistance (R-ARV). We determined the performance of three early warning indicators (EWIs) associated with a high risk of R-ARV emergence in Burkina Faso through a repeated cross-sectional study between 2014 and 2017. We analyzed the evolution of the DPIs of R-ARV emergence over this period. These were DPI1 (Timely withdrawal of ARVs), DPI2 (Retention on ARV treatment "TARV" at 12 months) and DPI4 (ARV prescription practices). A total of 27 sites were evaluated. The median number of patients who withdrew ART on time changed from 61% in 2015, 60% in 2016 and 58% in 2017, respectively. No site reached the threshold of at least 95% in the 2014and 2015 cohorts. The medians of retention on ART at 12 months for the 2014, 2015 and 2016 cohorts were 70%, 69% and 65% respectively. The 12-month ART retention threshold of at least 85% was only reached at two sites. Although ARV prescribing is in line with national guidelines, the quality of care offered to PLHIV regressed from 2014 to 2017 with a high risk of R-ARV emergence. To minimize this risk, therapeutic patient education and the system for tracking lost patients need to be strengthened.

Introduction: HIV2 is endemic in West Africa. In Burkina Faso, its prevalence was estimated at 2%. The aim of this work was to evaluate the follow-up of patients and also to contribute to the availability of data. Methods: We involved 18 years or older. Infection was screened according to the national algorithm. A cross- sectional study from first June 2017 to 31 December 2017 was performed. For each patient, sociodemographic, clinical, biological, therapeutic and evolution data were collected and analyzed. Results: The proportion of patients infected with HIV2 (n = 48; 1.7%) and HIV2 + 1 (n = 67; 2.4%) was 4.3%. The sex rat mean age was 50.3 ± 8.5 years. The combination of 2INTI + LPV/r was the most prescribed (n = 73; 63.5%). The average gain of LTCD4 has evolved from + 236 cells/mm3 in 2011 to + 364 cells/mm3 in 2015. The retention rate at grade 5 was about 70%. Conclusion: The immunological and clinic response of the patients was satisfactory. More than half of the patients remained in the continuum of care after five years of follow-up.

PURPOSE: Intermittent preventive treatment of malaria with sulphadoxine-pyrimethamine for pregnant women (IPTp-SP) coverage remains far below the desirable goal of at least three doses before delivery. This study evaluates an innovative intervention using mobile phones as a means of increasing coverage for the third dose of IPTp-SP. METHODS: This study in Burkina Faso was designed as an open-label, pragmatic, two-arm, randomised trial. Pregnant women who attended antenatal clinic (ANC) visits were included at their first ANC visit and followed until delivery. The intervention was built around the use of mobile phones as means ensuring direct tracking of pregnant women. RESULTS: Two hundred and forty-eight (248) pregnant women were included in the study. The proportion of women who received at least three doses of IPTp-SP was 54.6 %. In the intervention group, 54.1 % of women received at least three doses of IPTp-SP versus 55.1 % in the control group, a non-significant difference (adjusted odds ratio "aOR", 0.86 ; 95 % confidence interval "95 % CI", 0.49-1.51). Women in the intervention group were more likely to carry out their ANC visits in a timely manner than those in the control group (aOR, 3.21 ; 95 % CI, 1.91-5.39). CONCLUSION: While mobile phone intervention did not increase the proportion of women receiving three doses of IPTp-SP, it did help to increase the proportion of timely ANC visits. TRIAL REGISTRATION: PACTR202106905150440.

BACKGROUND AND OBJECTIVES: Breast cancer is the most common cancer in women. The objective is to study the survival of patients operated on for breast cancer. METHODS: Descriptive and analytical study of the survival of patients operated on for breast cancer between January 1, 2013 and December 31, 2020 in Ouagadougou. Survival was assessed by the Kaplan-Meier method and comparisons by the log-rank test. Prognostic factors were determined using the Cox model. RESULTS: We collected 550 cases. Overall survival at 5 years was 66.2%. Those under 30 years of age had a low 5-year overall survival (53%). The 5-year overall survival was poor in rural patients (63.5%), triple-negative patients (77.2%), HER2+ patients (50.5%) and stage IV patients (29.8%). In multivariate analysis, higher education (p < 0.001) and higher socioeconomic level (p < 0.001) were associated with better prognoses. CONCLUSIONS: The survival of patients operated on for breast cancer remains to be improved. It is influenced by multiple factors especially the socio-economic and educational level of the patients.

INTRODUCTION: Placental malaria (PM) is an important predictor of infant morbidity and mortality in sub-Saharan Africa. Although placental histology is the gold standard test to diagnose PM, the placenta impression smears remains widely used in epidemiological studies. This study is set to evaluate the performance of placental impression smears to detect PM in pregnant women in southern Benin. METHODS: A cross-sectional analysis was performed on data collected in the framework a multicenter randomized clinical trial (Malaria in Pregnancy Preventive and Alternative Drugs). Samples from 491 pregnant women were examined in the district of Allada, Southern Benin. Plasmodium falciparum infections have been assessed in placental blood and placental biopsy. RESULTS: Placental malaria detected by placenta impression smears and histology were prevalent in 11.4% and 10.8%, respectively. Sensitivity and specificity of placental impression smears were 90.6% and 98.4%. Among 55 pregnant women tested positive by placenta impression smears, 48 were positive by the histology, while 7 were negative (positive predictive value: 87.3%). Four hundred and twenty four (424) of the 429 tested negative by the placenta impression smears, were also negative according to histology whereas the rest (5 of 429) of the women were positive (negative predictive value: 98.8%). CONCLUSION: Placenta impression smear is an accurate and easy method for the diagnosis of placental malaria.

INTRODUCTION: Vulvar cancer is rare and belatedly diagnosed in Africa. We describe its diagnostic stages, therapeutic and evolution features in a country with limited resources. METHODOLOGY: Forty-seven cases of vulvar cancer diagnosed between 2013 and 2018 in Burkina Faso, were analyzed retrospectively. The diagnostic stages, therapeutic and evolution terms were considered. Survival was calculated through the Kaplan Meier Method and compared using the Logrank technique. RESULTS: Stages IA and IB accounted for 10.6%. Radiotherapy was not available and chemotherapy was done in 9 cases. Full vulvectomy with bilateral inguino-femoral dissection was performed in 11 cases. Average survival was 41 months with a median of 52 months. The difference in survival according to the diagnostic stages were highly significant statistically (P=0.000). DISCUSSION: Cancer of the vulva is rare and raises major therapeutic difficulties in countries with limited resources. Surgery is the only affordable weapon. Evolution would be better if radiochemotherapy was possible. CONCLUSION: Radiochemotherapy cannot be done due to the lack of a radiotherapy unit and the high cost of cytotoxics. Surgery is largely palliative and/or mutilating. Survival is modest. An early diagnosis could help promote conserving treatments.

BACKGROUND: According to the Developmental Origins of Health and Diseases paradigm, the fetal period is highly vulnerable and may have profound effects on later health. Few studies assessed the effect of small-for-gestational age (SGA), a proxy for fetal growth impairment, on risk of malaria during infancy in Africa. METHODS: We used data from a cohort of 398 mother-child pairs, followed from early pregnancy to age 1 year in Benin. Malaria was actively and passively screened using thick blood smear. We assessed the effect of SGA on risk of malaria infection and clinical malaria from birth to 12 months, after stratifying on the infant's age using a logistic mixed regression model. RESULTS: After adjustment for potential confounding factors and infant's exposure to mosquitoes, SGA was associated with a 2-times higher risk of malaria infection (adjusted odds ratio [aOR] = 2.16; 95% confidence interval [CI], 1.04-4.51; P = .039) and clinical malaria (aOR = 2.33; 95% CI, 1.09-4.98; P = .030) after age 6 months. CONCLUSION: Results suggest higher risk of malaria during the second semester of life in SGA infants, and argue for better follow-up of these infants after birth, as currently for preterm babies.

BACKGROUND: At times, ultrasound is not readily available in low resource countries in Africa for accurate determination of gestational age, so using alternative methods is pivotal during pregnancy. These assessments are used to aid the risk analysis for an infant and management strategies for premature delivery, if necessary. Currently, date of last menstrual period, fundal height measurements, and the New Ballard Score are commonly used in resource-limited settings. However, concordance of these measures is unknown for sub-Saharan Africa. We obtained data from an open-label randomized controlled trial, to assess the concordance of these alternative assessment methods. The purpose of our study was to determine the agreement between these alternative methods when used in sub-Saharan African populations. METHODS: A total of 4,390 pregnant women from Benin, Gabon, Mozambique and Tanzania were included in our analysis. The assessment methods compared were: 1) reported last menstrual period, 2) symphysis-fundal height measurement, and 3) the New Ballard Score. The Bland-Altman method and intraclass correlation coefficient (ICC) were used to test the degree of agreement. Survival range gestational age, used as an inclusion criterion for further analysis, was from 22 to 44 weeks. FINDINGS: Plots showed a lack of agreement between methods and the 95% limits of agreement too wide to be clinically useful. ICC = 0.25 indicated poor agreement. A post-hoc analysis, restricted from 32 to 42 weeks, was done to check for better agreement in this near-term population. The plots and ICC = 0.16 still confirmed poor agreement. CONCLUSION: The alternative assessments do not result in comparable outcomes and discrepancies are far beyond the clinically acceptable range. Last menstrual period should not be used as the only estimator of gestational age. In the absence of reliable early ultrasound, symphysis-fundal height measurements may be most useful during pregnancy for fetal risk assessment and the New Ballard Score after delivery as a confirmation of these estimations and for further neonatal management. However, promotion of portable ultrasound devices is required for accurate assessment of gestational age in sub-Sahara Africa.

OBJECTIVES: To investigate whether high-dosed folate supplements might diminish the efficacy of malaria intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) in a cohort of pregnant women in Benin, where malaria is holoendemic. METHODS: We followed 318 women during the entire pregnancy and analysed haematological and Plasmodium falciparum indicators in the context of an intermittent preventive treatment trial in Benin. During the follow-up, women received two-dose IPTp (1500/75 mg of SP per dose) at the maternity clinic and 600 mg of albendazole, 200 mg ferrous sulphate and 5 mg folic acid per day for home treatment. RESULTS: High folate levels were not associated with increased malaria risk (adjusted OR (aOR) = 0.51 (95% CI: 0.17; 1.56, P-value = 0.24)), nor with increased P. falciparum density (beta coefficient = -0.26 (95% CI: -0.53; 0.02), P-value = 0.07) in a randomised trial of IPTp in Benin. On the contrary, higher iron levels were statistically associated with increased odds of a positive blood smear (aOR = 1.7 95% CI (1.2; 2.3), P-value < 0.001) and P. falciparum parasite density (beta coefficient = 0.2 95% CI (0.1; 0.3), P-value < 0.001). High folate levels were statistically associated with decreased odds of anaemia (aOR = -0.30 95% CI (0.10; 0.88), P-value = 0.03). CONCLUSIONS: High folate levels are not associated with increased malarial risk in a prospective longitudinal cohort in the context of both iron and high-dosed folate supplements and IPTp. They are associated with reduced risk of anaemia, which is particularly important because iron, also given to treat anaemia, might be associated with increased malaria risk.

BACKGROUND: Male breast cancer is a rare and less known disease. Therapeutic modalities affect survival. In Burkina Faso, male breast cancers are diagnosed in everyday practice, but the prognosis at short-, middle-, and long-term remains unknown. The objective of this study is to study the diagnosis stages, therapeutic modalities, and 5-year survival in male breast cancer at the General Surgery Unit of Yalgado Ouedraogo University Hospital from 1990 to 2009. METHODS: A cohort longitudinal study concerning cases of breast cancer diagnosed in man. Survival was assessed using the Kaplan-Meier method and survival curves were compared through the LogRank test. RESULTS: Fifty-one cases of male breast cancer were followed-up, i.e., 2.6% of all breast cancers. Stages III and IV represented 88% of cases. Eleven patients (21.6%) were at metastatic stage. Patients were operated in 60.8% of cases. The surgery included axillary dissection in 25 (80.6%) out of 31 cases. Lumpectomy was performed on 6.5% of patients (2 cases). Fifteen (29.4%) and 11 (21.6%) patients underwent chemotherapy and hormonal therapy, respectively. The FAC protocol was mostly used. Radiation therapy was possible in two cases. The median deadline for follow-up was 14.8 months. A local recurrence was noticed in 3.2% of cases. The overall 5-year survival rate was 49.9%. The median survival was over 5 years for stages I and II. It was 54 down to 36 months for stages III and IV. CONCLUSION: Diagnosis is late. The lack of immunohistochemistry makes it difficult to define the proportion of their hormonal dependence. Surgery is the basic treatment. Five-year survival is slow and the median survival depends on the diagnosis stage. It can be improved through awareness-raising campaigns and the conduct of individual screening.

The World Health Organization (WHO) estimates that 40% of children in low-income countries are anemic. Therefore, iron supplements are recommended by WHO in areas with high anemia rates. However, some studies have set into question the benefits of iron supplementation in malaria-endemic regions. In Benin, a west African country with high prevalence of anemia and malaria, no iron supplements are given systematically to infants so far despite the WHO recommendations. In this context, we wanted to investigate the effect of iron levels during the first year of life on malarial risk in Benin considering complementary risk factors. We followed 400 women and their offspring between January 2010 and June 2012 in Allada (Benin). Environmental, obstetric, and numerous clinical, maternal, and infant risk factors were considered. In multilevel models, high iron levels were significantly associated with the risk of a positive blood smear (adjusted odds ratio = 2.90, P < 0.001) and Plasmodium falciparum parasitemia (beta estimate = 0.38, P < 0.001). Infants with iron levels in the lowest quartile were less likely to have a positive blood smear (P < 0.001), and the risk increased with higher iron levels. Our results appeal for additional evaluation of the effect of different doses of iron supplements on the infant health status, including malaria incidence. Thus, the health status of infants should be compared between cohorts where iron is given either for prevention or anemia treatment, to better understand the effect of iron supplements on infant health.

BACKGROUND: In sub-Saharan Africa, few studies exist on elderly HIV-positive populations. Therefore, we aimed to examine the profiles of elderly people living with HIV (PLHIV) in Burkina Faso and their response to antiretroviral therapy (ART). METHODS: We reviewed the monitoring and treatment of PLHIV over the age of 50 years and then compared with the monitoring and treatment of PLHIV under 50 years. RESULTS: A total of 3367 patients were included. The median age of elderly people was 54.5 years and of young people was 34.9 years ( P = .03). In both the groups, screening was performed following clinical suspicion (64.9% in elderly versus 56% in young people; P < .001). Cardiovascular risk factors were generally more significant in the elderly people. The risk of death while on ART was 2.3 times higher in elderly people ( P < .001). CONCLUSION: HIV infection in older people occurs in those who already have some cardiovascular risk factors. Particular attention should be given to multidisciplinary care for the elderly individuals.

AIM: To study spontaneous reporting of adverse effects of antimalarial drugs sent to pharmacovigilance national center. METHOD: A cross-sectional study was conducted to explore spontaneous reporting of adverse effects of antimalarial drugs sent to pharmacovigilance center from January 1, 2009 to December 31, 2013. RESULTS: In total 104 spontaneous reporting forms regarding antimalarial drugs were analysed. The sex ratiowas (male/female) 0,8. The majority of patients were aged over 13 years (66,3%). Self-medication and use of concomitant drug (>2) were observed in 22,1% and 46,2% of cases respectively. The artemisinin-based combination therapies (ACTs) were used in 77,8%. Several categories of adverse effects were observed among which skin and annexes disorders(34,6%), disorders of general health conditions, (29,8%), central nervous system disorders(29,8%), gastro-enterological disorders (23,0%). The most part of adverse effects was mild (67,3%).The adverse effects regarding central nervous (p=0,009)and gastro-enterological (p=0,0009) systems were significantly associated to the ACT use compared with use of other antimalarial drugs. CONCLUSION: These results show the importance to implement active surveillance of ACTs to have a safety profile in our real conditions of use.

Les effets indésirables survenaient dans des circonstances d'automédication, de traitement concomitant de plus de deux médicaments dans 22,1% et 46,2% des cas respectivement. Les combinaisons thérapeutiques à base d'artémisinine (CTA) représentaient 77,8% des cas. Plusieurs types d'effets indésirables ont été observés, parmi lesquels les atteintes de la peau et ses annexes (34,6%), les troubles de l'état (29,8%),les troubles du système nerveux (29,8%), les troubles gastroentérologiques (23,0%). Les effets indésirables étaient le plus souvent modérés (67,3%). Ceux se rapportant au système nerveux (p=0,009) et à l'appareil gastroentérologique(p=0,0009) étaient associés significativement à l'utilisation d'une CTA. CONCLUSION: Ces résultats montrent la nécessité d'une surveillance plus intense des CTA pour mieux décrire leur profil de tolérance dans nos conditions réelles d'utilisation.
RESUMEN
OBJECTIVES: One of Africa's most important challenges is to improve maternal and neonatal health. The identification of groups at highest risk for adverse pregnancy outcomes is important for developing and implementing targeted prevention programmes. This study assessed whether young adolescent girls constitute a group at increased risk for adverse birth outcomes among pregnant women in sub-Saharan Africa. SETTING: Data were collected prospectively as part of a large randomised controlled clinical trial evaluating intermittent preventive treatment of malaria in pregnancy (NCT00811421-Clinical Trials.gov), conducted between September 2009 and December 2013 in Benin, Gabon, Mozambique and Tanzania. PARTICIPANTS: Of 4749 participants, pregnancy outcomes were collected for 4388 deliveries with 4183 live births including 83 multiple gestations. Of 4100 mothers with a singleton live birth delivery, 24% (975/4100) were adolescents (≤19â years of age) and 6% (248/4100) were aged ≤16â years. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcomes of this predefined analysis were preterm delivery and low birth weight. RESULTS: The overall prevalence of low birthweight infants and preterm delivery was 10% (371/3851) and 4% (159/3862), respectively. Mothers aged ≤16â years showed higher risk for the delivery of a low birthweight infant (OR: 1.96; 95% CI 1.35 to 2.83). Similarly, preterm delivery was associated with young maternal age (≤16â years; OR: 2.62; 95% CI 1.59 to 4.30). In a subanalysis restricted to primiparous women: preterm delivery, OR 4.28; 95% CI 2.05 to 8.93; low birth weight, OR: 1.29; 95% CI 0.82 to 2.01. CONCLUSIONS: Young maternal age increases the risk for adverse pregnancy outcomes and it is a stronger predictor for low birth weight and preterm delivery than other established risk factors in sub-Saharan Africa. This finding highlights the need to improve adolescent reproductive health in sub-Saharan Africa. TRIAL REGISTRATION NUMBER: NCT00811421; Post-results.

BACKGROUND: Little is known about the effects of intermittent preventive treatment of malaria in pregnancy (IPTp) on the health of sub-Saharan African infants. We have evaluated the safety of IPTp with mefloquine (MQ) compared to sulfadoxine-pyrimethamine (SP) for important infant health and developmental outcomes. METHODS AND FINDINGS: In the context of a multicenter randomized controlled trial evaluating the safety and efficacy of IPTp with MQ compared to SP in pregnancy carried out in four sub-Saharan countries (Mozambique, Benin, Gabon, and Tanzania), 4,247 newborns, 2,815 born to women who received MQ and 1,432 born to women who received SP for IPTp, were followed up until 12 mo of age. Anthropometric parameters and psychomotor development were assessed at 1, 9, and 12 mo of age, and the incidence of malaria, anemia, hospital admissions, outpatient visits, and mortality were determined until 12 mo of age. No significant differences were found in the proportion of infants with stunting, underweight, wasting, and severe acute malnutrition at 1, 9, and 12 mo of age between infants born to women who were on IPTp with MQ versus SP. Except for three items evaluated at 9 mo of age, no significant differences were observed in the psychomotor development milestones assessed. Incidence of malaria, anemia, hospital admissions, outpatient visits, and mortality were similar between the two groups. Information on the outcomes at 12 mo of age was unavailable in 26% of the infants, 761 (27%) from the MQ group and 377 (26%) from the SP group. Reasons for not completing the study were death (4% of total study population), study withdrawal (6%), migration (8%), and loss to follow-up (9%). CONCLUSIONS: No significant differences were found between IPTp with MQ and SP administered in pregnancy on infant mortality, morbidity, and nutritional outcomes. The poorer performance on certain psychomotor development milestones at 9 mo of age in children born to women in the MQ group compared to those in the SP group may deserve further studies.
