Consistent condom use among highly effective contraceptive users in an HIV-endemic area in rural Kenya.

BackgroundWomen of reproductive age are at the highest risk of both HIV infection and unintended pregnancy in sub-Saharan Africa. Highly effective contraceptives (HECs) such as hormonal injectable and implants are widely used in this region. HECs are effective for preventing pregnancies. However, unlike condoms, HECs offer no protection against HIV. Dual-method use, or the use of condoms with HECs, is an ideal option to reduce HIV risk but is infrequently practiced. Rather, women tend not to use condoms when they use HECs and increase their HIV risk from their sexual partners. However, it remains unknown whether HIV status affects such tendency. Given the increasing popularity of HECs in sub-Saharan Africa, this study examined the association between the use of HECs and condom use among HIV-positive and negative women.MethodsA cross-sectional study was conducted among 833 sexually active women aged 18–49 years, recruited from six clinics in Siaya county, Kenya. From March to May 2017, female research assistants interviewed the women using a structured questionnaire. Multiple logistic regression analysis was conducted to examine the association between HEC use and consistent condom use in the past 90 days, adjusting for potential confounders. It was also examined with regular partners (husbands or live-in partners) and non-regular partners, separately. In addition, a sub-sample analysis of HIV-negative or unknown women was conducted.ResultsIn total, 735 women were available for the analysis. Among the women, 231 (31.4%) were HIV-positive. HIV-positive women were more likely to use HECs than HIV-negative or status unknown women (70.1% vs. 61.7%, p = 0.027). HEC use was significantly associated with decreased condom use with a regular partner (adjusted odds ratio (AOR) = 0.25; 95% CI 0.15–0.43, p<0.001) and a non-regular partner (AOR = 0.25; 95% CI 0.11–0.58, p = 0.001). However, compared with HIV-negative or status unknown women, HIV-positive women were more likely to use HECs and condoms consistently with a regular partner (AOR = 6.54, 95% CI 2.15–20.00, p = 0.001). Other factors significantly associated with consistent condom use included partner’s positive attitude toward contraception, partner’s HIV-positive status, high HIV risk perception, and desire for children in the future.ConclusionDual-method use was limited among HIV-negative women and women who had HIV-negative partners due to inconsistent condom use. The use of HECs was significantly associated with decreased condom use, regardless of partner type and their HIV status. Due to this inverse association, HIV-negative women may increase their HIV risk from their sexual partners. Therefore, interventions should be strengthened to reduce their dual risks of HIV infection and unintended pregnancy by promoting dual-method use. Family planning services should strengthen counseling on the possible risk of HIV infection from their sexual partners and target not only women but also their partners, who may play a key role in condom use.

Preconceptional factors associated with haemoglobin concentration in early pregnancy: a community-based cohort study in rural northeastern Tanzania.

Maternal anaemia in early pregnancy is associated with poor pregnancy outcomes. Furthermore, preconceptional health can influence the health during pregnancy. The aim of this study was to investigate which preconceptional factors were associated with haemoglobin (Hb) concentration in early pregnancy. In Tanzania, 226 women were followed at preconception and during early pregnancy. Red blood cell (RBC) morphology, serum micronutrient concentration, demographic characteristics and health status were assessed in preconception and in early pregnancy. The association between preconceptional factors and Hb concentration in early pregnancy was investigated using simple and multiple linear regression analyses stratified by preconceptional anaemia status. Mean Hb was 123 and 119g/l before conception and during early pregnancy (median gestational age 53days) respectively. Preconceptional mid-upper arm circumference (MUAC) (adjusted coefficient (AC) 0.35 95% CI 0.9-0.61) and preconceptional Hb concentration (AC 0.45 95% CI 0.36-0.54) were positively associated with early pregnancy Hb concentration, whereas preconceptional microcytic hypochromic RBC morphology (AC -6.00 95% CI -9.56 to -2.44) was negatively associated with early pregnancy Hb concentration. In addition, treatment of preconceptional malaria was positively associated with early pregnancy Hb concentration (AC 6.45 95% CI 0.74-12.2) among women with preconceptional anaemia. In contrast, among preconceptional non-anaemic women, only preconceptional Hb concentration and medium socio-economic status was positively associated with early pregnancy Hb concentration. Mid-upper arm circumference (MUAC) and Hb measurements in preconception can help to detect women at increased risk of low Hb concentration in early pregnancy.

Reproductive decision-making among postpartum HIV-infected women in rural South Africa.

Despite pregnancy spacing recommendations to optimize health outcomes among mothers and neonates, unplanned pregnancy in sub-Saharan Africa is common among women living with human immunodeficiency virus (HIV) (WLHIV). This study examined factors associated with reproductive decision-making among WLHIV to inform pregnancy-planning interventions. WLHIV in rural South Africa (n = 165) were assessed at 12 months postpartum. The relative importance of factors associated with reproductive decision-making was estimated. Women were a mean of 28 years old (SD = 5.71). Risk of mother-to-child transmission (MTCT) of HIV (Mean = 0.43; SD = 0.33) had the greatest impact on decision-making, followed by partners' desires (M = 0.22; SD = 0.18), family preferences (M = 0.18; SD = 0.13), and community opinion (M = 0.17; SD = 0.13). MTCT was most important to women with greater HIV knowledge. However, WLHIV who had been diagnosed with HIV for a longer time placed more emphasis on partner preference and community opinion, and less importance on MTCT risk. Prevention of mother-to-child transmission (PMTCT) was less important to women experiencing intimate partner violence and those with depression. Findings highlight the need for tailored, focused interventions to support the unique circumstances of WLHIV and support the inclusion of families and/or partners in the counseling process. Results underscore the need for perinatal preconception counseling for women during routine HIV care.

Prevalence, predictors and adverse outcomes of adolescent pregnancy in sub-Saharan Africa: a protocol of a systematic review

BackgroundSeveral studies have reported on factors influencing adolescent pregnancies and the associated outcomes, but evidence from a systematic review is limited, especially in sub-Saharan Africa where the greater burden lies. Establishment of accurate epidemiological data on the rates of adolescent pregnancy, its predictors, and adverse outcomes (maternal and neonatal) may have important implications towards attainment of the Sustainable Development Goals.MethodsThis will be a systematic review of studies reporting predictors of adolescent pregnancy and adverse outcomes in sub-Saharan Africa published between January 2000 and December 2017. The following databases will be searched: PubMed/MEDLINE, Excerpta Medica Database (EMBASE), SCOPUS, Popline, Africa Wide Information, African Index Medicus, Google scholar and the Cochrane library. Three authors will independently screen all potential articles for eligibility as guided by the selection criteria. The Stata statistical software will be used in analysing the data. Appropriate meta-analytic techniques will be used to pool prevalence estimates from studies with similar features, overall and by major subgroups as warranted. Heterogeneity of studies will be evaluated by the χ2 test on Cochrane’s Q statistic. Publication bias will be sorted for using funnel plot analysis and Egger’s test. Qualitative synthesis will be used where data are insufficient to produce a quantitative synthesis. This protocol is reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols (PRISMA-P) 2015 guidelines.DiscussionThis systematic review and meta-analysis is expected to serve as a template for designing adolescent-friendly preventive and control programmes to help curb the ever-growing burden of adolescent pregnancies, and as a guide for future research.Systematic review registrationPROSPERO CRD42017070773

Prevalence of hyperglycaemia first detected during pregnancy and subsequent obstetric outcomes at St. Francis Hospital Nsambya

BackgroundWomen with hyperglycaemia detected during pregnancy are at greater risk for adverse pregnancy outcomes. Data on hyperglycaemia in pregnancy in sub-Saharan Africa is scanty and varied depending on the populations studied and the methodologies used to define hyperglycaemia in pregnancy. With the recent 2013 World Health Organisation (WHO) diagnostic criteria and classification, there is yet no sufficient data on the prevalence of hyperglycaemia in sub-Saharan Africa. The objective was to determine the prevalence of Hyperglycaemia first detected during pregnancy and subsequent obstetric outcomes among patients attending antenatal care (ANC) at St. Francis Hospital Nsambya.MethodsA prospective cohort study. All women with no history of diabetes mellitus attending at or after 24 weeks gestation were eligible to participate in the study. Participants underwent a standard 75 g oral glucose tolerance test (OGTT) after an informed written consent. The primary outcome was diagnosis of hyperglycaemia. Enrolled participants were followed up to delivery to assess obstetric outcomes (secondary outcomes were birth weight, neonatal admission, maternal genital trauma, delivery mode, neonatal and maternal status at discharge).Results251 women were screened between December 2013 and February 2014. The prevalence of hyperglycaemia first detected in pregnancy was 31.9%. We found 23.8 % of women with hyperglycaemia had no known risk factor. Macrosomia was the only obstetric outcome that was significantly associated with hyperglycaemia.ConclusionThe prevalence of hyperglycaemia first detected in pregnancy was high in the studied population. Clinicians, therefore, should become more vigilant to screen for the condition. Selective screening may miss 23.8% of pregnant women with hyperglycaemia. However the cost/benefit implications of screening strategy and the recent 2013 WHO diagnostic criteria need to be studied in our setting.

Prevalence of congenital malaria in newborns of mothers co-infected with HIV and malaria in Benin city

Background: HIV and Plasmodium falciparum malaria co-infection annually complicates about one million pregnancies in sub-Saharan Africa. Congenital malaria (CM) has deleterious effects on newborns. Little is known about the effect of co-infections on the prevalence of CM in infants born by these women. This study was carried out to determine the prevalence of CM in newborns of mothers co-infected with HIV and malaria compared to HIV-negative mothers with malaria in Benin-City.Methods: Subjects were 162 newborns of mothers co-infected with HIV and malaria. Controls were 162 newborns of HIV negative malaria infected mothers. Blood film for malaria parasites was done on cord blood and peripheral blood on days 1, 3 and 7 in the newborns. Maternal peripheral blood film for malaria parasite was done at delivery and placental tissue was obtained for confirmation of placental malaria by histology. Diagnosis of malaria in blood films was by light microscopy.Results: The prevalence of CM in subjects was significantly higher than in controls (34.6% and 22.2%, p=.014). Profound immunodepression (maternal CD4 cell count <200 cell/mm3) was significantly associated with CM (p=.006). The major predictors of CM in subjects were maternal CD4 cell count <200 cell/mm3 and placental malaria while in controls placental malaria was the only predictor.Conclusions: Babies born to mothers co-infected with HIV and malaria are at increased risk for CM. All babies born by HIV positive mothers should be screened for CM.

Trial of ready-to-use supplemental food and corn-soy blend in pregnant Malawian women with moderate malnutrition: a randomized controlled clinical trial

Malnutrition during pregnancy in sub-Saharan Africa is associated with poor birth outcomes. This study compared maternal and offspring anthropometry for moderately malnourished pregnant women receiving ready-to-use supplemental food (RUSF), a fortified corn-soy blend (CSB+) with a daily multiple micronutrient antenatal supplement [United Nations International Multiple Micronutrient Preparation (UNIMMAP)], or standard of care comprising CSB+ and iron and folic acid (IFA). A single-blind randomized controlled clinical trial was conducted in southern Malawi among 1828 pregnant women with moderate malnutrition, defined as a midupper arm circumference (MUAC) ≥20.6 and ≤23.0 cm. Women received 1 of 3 dietary treatment regimens that provided ∼900 kcal/d and 33-36 g protein/d. Maternal and infant anthropometry were followed until the child was 3 mo old. Newborns had a mean length-for-age z score of -1.3 ± 1.2 and 22% were stunted at birth. Mothers receiving RUSF had the highest weight gain during supplementation (3.4 ± 2.6, 3.0 ± 2.2, and 3.2 ± 2.4 kg for the RUSF, CSB+ with UNIMMAP, and CSB+ with IFA groups, respectively; P = 0.03). Newborn birth weights and lengths were similar across intervention groups, but the incidence of newborns with a birth weight <2.4 kg (weight-for-age z score <-2) was higher in the CSB+ with UNIMMAP group than the other groups (17%, 18%, and 24% for the CSB+ with IFA, RUSF, and CSB+ with UNIMMAP groups, respectively; P = 0.02). At birth, HIV-exposed newborns had a similar length and weight as newborns without HIV exposure, but their head circumference was smaller (34.0 ± 1.5 and 34.3 ± 1.6 cm, respectively; P = 0.02). At 3 mo of age, HIV-exposed infants had smaller weights, lengths, and head and arm circumferences than infants without HIV exposure. RUSF improved maternal weight gain compared with CSB+ with UNIMMAP. The large amount of food given and the modest effect on linear growth in newborns suggests that stunting in utero is unlikely to be reduced by supplemental food alone. This trial was registered at clinicaltrials.gov as NCT02120599.

Framework for Evaluating the Health Impact of the Scale-Up of Malaria Control Interventions on All-Cause Child Mortality in Sub-Saharan Africa.

.Concerted efforts from national and international partners have scaled up malaria control interventions, including insecticide-treated nets, indoor residual spraying, diagnostics, prompt and effective treatment of malaria cases, and intermittent preventive treatment during pregnancy in sub-Saharan Africa (SSA). This scale-up warrants an assessment of its health impact to guide future efforts and investments; however, measuring malaria-specific mortality and the overall impact of malaria control interventions remains challenging. In 2007, Roll Back Malaria's Monitoring and Evaluation Reference Group proposed a theoretical framework for evaluating the impact of full-coverage malaria control interventions on morbidity and mortality in high-burden SSA countries. Recently, several evaluations have contributed new ideas and lessons to strengthen this plausibility design. This paper harnesses that new evaluation experience to expand the framework, with additional features, such as stratification, to examine subgroups most likely to experience improvement if control programs are working; the use of a national platform framework; and analysis of complete birth histories from national household surveys. The refined framework has shown that, despite persisting data challenges, combining multiple sources of data, considering potential contributions from both fundamental and proximate contextual factors, and conducting subnational analyses allows identification of the plausible contributions of malaria control interventions on malaria morbidity and mortality.

Clinical interventions to reduce stillbirths in sub-Saharan Africa: a mathematical model to estimate the potential reduction of stillbirths associated with specific obstetric conditions.

Stillbirths are among the most common adverse pregnancy outcomes, with 98% occurring in low-income countries. More than one-third occur in sub-Saharan Africa (SSA). However, the medical conditions causing stillbirths and interventions to reduce stillbirths from these conditions are not well documented. We estimated the reductions in stillbirths possible with combinations of interventions. We developed a computerised model to estimate the impact of various interventions on stillbirths caused by the most common conditions. The model considered the location of obstetric care (home, clinic or hospital) and each intervention's efficacy, penetration and utilisation. Maternal transfers were also considered. Pregnancies in SSA in 2012. For each condition, we created a series of scenarios involving different combinations of interventions and modelled their impact on stillbirth rates. Stillbirths associated with various maternal and fetal conditions and the percentage reduction with various interventions. Eight to ten maternal and fetal conditions were responsible for most stillbirths, but none for more than 15%. The most common conditions causing stillbirths in SSA include obstructed labour and uterine rupture, fetal distress and umbilical cord complications, fetal growth restriction, pre-eclampsia/eclampsia, and placental abruption/placenta praevia. Syphilis and malaria contribute smaller numbers. Reducing stillbirths requires appropriate diagnosis and management of each condition, usually including hospital care for monitoring and delivery, often by caesarean section. Maternal syphilis and malaria were the only conditions for which outpatient management alone reduced stillbirth. Most stillbirths in low-income countries occur at term and during labour and therefore are preventable by appropriate obstetric care. Management focused on the maternal and fetal conditions that cause stillbirths is necessary to achieve stillbirth rates approaching those found in high-income countries. Reducing stillbirth incidence requires appropriate management of each causative condition and often caesarean delivery.

Factors Associated with Teen Pregnancy in sub-Saharan Africa: A Multi-Country Cross-Sectional Study

This study aimed to assess the contextual factors associated with teenage pregnancy in sub-Saharan Africa. Using DHS data we modelled females aged 15-19 with multilevel logistic regression to establish the independent influence of social disadvantage on teenage pregnancy in West, East and Southern Africa with aid of the MLwiN programme. Results showed teenage pregnancy decreased in East Africa, plateaued in West Africa and increased slightly in Southern Africa between 1992 and 2011. Multilevel multivariate regression revealed teenage pregnancy was associated with family disruption (0.39; 0.40: P<0.05), community-levels of female unemployment (1.01; 0.99: P<0.05) and community poverty (1.01; 1.02: P<0.05) in Southern and East Africa, while only community poverty (1.01; P<0.05) independently predicted the outcome in West Africa. Our findings emphasise the necessity of creating regional-specific interventions and prevention campaigns to address multilevel factors such as family disruption as well as the need for governments to address issues of unemployment, poverty and inequality.

Prevention of Mother-to-Child Transmission of Hepatitis B in the Urban District Health Baskuy Burkina Faso

Few studies have been conducted on the epidemiology in pregnancy in sub-Saharan Africa. This study aimed to improve the care of pregnant women infected with hepatitis B virus (VHB) and their newborns in the urban district health. Method: This study was conducted from 01/09/2014 to 01/09/2015. Study involved three types of data collection: a collection of data from health facilities involved in the project; repeated cross-sectional survey among health personnel; a pros- pective study of pregnant women identified positive for HBsAg and followed at the University Hospital Yalgado Ouedraogo (CHU-YO). Knowledge assessment was made among health staff and pregnant women using a knowledge score. Construction of the score came after a factorial analysis of multiple correspondences on population health workers surveyed in the first round (N = 119) on one hand and all pregnant women (N = 266) on the other hand. This had identified among the 79/19 questions, those that discriminated best knowledge of paramedics and pregnant women. For pregnant women, this score was then dichotomized from the center and logistic regression was performed to determine the sociodemographic, medical and obstetric characteristics that influenced it (p value < 005). Results: Health staff had been surveyed twice (N = 119/100). In general, the level of knowledge was good on targeted knowledge, both before and after training. No health worker routinely offered screening for hepatitis B among pregnant women attending antenatal clinics. Altogether 266 pregnant women HBsAg-positive were referred and followed CHU-YO. Half of the patients had a score lower than 2/17. Univariate analysis showed that variables such as education level influenced significantly the level of knowledge. Women with higher levels of education had a higher level of knowledge about the disease, compared to those of primary level [OR = 1.63; [1.34 to 1.99], p value < 0,001]. Newborns during the study period numbered 128 and the vaccine was made in the first 24 hours of life for 83.6% of them. Conclusion: routine screening for infection with VHB during pregnancy and improved knowledge of mothers is strongly reco- mmended in Burkina Faso.

Intermittent screening and treatment or intermittent preventive treatment with dihydroartemisinin–piperaquine versus intermittent preventive treatment with sulfadoxine–pyrimethamine for the control of malaria during pregnancy in western Kenya: an open-label, three-group, randomised controlled superiority trial

Every year, more than 32 million pregnancies in sub-Saharan Africa are at risk of malaria infection and its adverse consequences. The effectiveness of the intermittent preventive treatment with sulfadoxine-pyrimethamine strategy recommended by WHO is threatened by high levels of parasite resistance. We aimed to assess the efficacy and safety of two alternative strategies: intermittent screening with malaria rapid diagnostic tests and treatment of women who test positive with dihydroartemisinin-piperaquine, and intermittent preventive treatment with dihydroartemisinin-piperaquine. We did this open-label, three-group, randomised controlled superiority trial at four sites in western Kenya with high malaria transmission and sulfadoxine-pyrimethamine resistance. HIV-negative pregnant women between 16 and 32 weeks' gestation were randomly assigned (1:1:1), via computer-generated permuted-block randomisation (block sizes of three, six, and nine), to receive intermittent screening and treatment with dihydroartemisinin-piperaquine, intermittent preventive treatment with dihydroartemisinin-piperaquine, or intermittent preventive treatment with sulfadoxine-pyrimethamine. Study participants, study clinic nurses, and the study coordinator were aware of treatment allocation, but allocation was concealed from study investigators, delivery unit nurses, and laboratory staff. The primary outcome was malaria infection at delivery, defined as a composite of peripheral or placental parasitaemia detected by placental histology, microscopy, or rapid diagnostic test. The primary analysis was by modified intention to treat. This study is registered with ClinicalTrials.gov, number NCT01669941. Between Aug 21, 2012, and June 19, 2014, we randomly assigned 1546 women to receive intermittent screening and treatment with dihydroartemisinin-piperaquine (n=515), intermittent preventive treatment with dihydroartemisinin-piperaquine (n=516), or intermittent preventive treatment with sulfadoxine-pyrimethamine (n=515); 1368 (88%) women comprised the intention-to-treat population for the primary endpoint. Prevalence of malaria infection at delivery was lower in the intermittent preventive treatment with dihydroartemisinin-piperaquine group than in the intermittent preventive treatment with sulfadoxine-pyrimethamine group (15 [3%] of 457 women vs 47 [10%] of 459 women; relative risk 0·32, 95% CI 0·18-0·56; p<0·0001), but not in the intermittent screening and treatment with dihydroartemisinin-piperaquine group (57 [13%] of 452 women; 1·23, 0·86-1·77; p=0·26). Compared with intermittent preventive treatment with sulfadoxine-pyrimethamine, intermittent preventive treatment with dihydroartemisinin-piperaquine was associated with a lower incidence of malaria infection during pregnancy (192·0 vs 54·4 events per 100 person-years; incidence rate ratio [IRR] 0·28, 95% CI 0·22-0·36; p<0·0001) and clinical malaria during pregnancy (37·9 vs 6·1 events; 0·16, 0·08-0·33; p<0·0001), whereas intermittent screening and treatment with dihydroartemisinin-piperaquine was associated with a higher incidence of malaria infection (232·0 events; 1·21, 1·03-1·41; p=0·0177) and clinical malaria (53·4 events; 1·41, 1·00-1·98; p=0·0475). We recorded 303 maternal and infant serious adverse events, which were least frequent in the intermittent preventive treatment with dihydroartemisinin-piperaquine group. At current levels of rapid diagnostic test sensitivity, intermittent screening and treatment is not a suitable alternative to intermittent preventive treatment with sulfadoxine-pyrimethamine in the context of high sulfadoxine-pyrimethamine resistance and malaria transmission. However, dihydroartemisinin-piperaquine is a promising alternative drug to replace sulfadoxine-pyrimethamine for intermittent preventive treatment. Future studies should investigate the efficacy, safety, operational feasibility, and cost-effectiveness of intermittent preventive treatment with dihydroartemisinin-piperaquine.

Integrating family planning into HIV care in western Kenya: HIV care providers’ perspectives and experiences one year following integration

ABSTRACTWith high rates of unintended pregnancy in sub-Saharan Africa, integration of family planning (FP) into HIV care is being explored as a strategy to reduce unmet need for contraception. Perspectives and experiences of healthcare providers are critical in order to create sustainable models of integrated care. This qualitative study offers insight into how HIV care providers view and experience the benefits and challenges of providing integrated FP/HIV services in Nyanza Province, Kenya. Sixteen individual interviews were conducted among healthcare workers at six public sector HIV care facilities one year after the implementation of integrated FP and HIV services. Data were transcribed and analyzed qualitatively using grounded theory methods and Atlas.ti. Providers reported a number of benefits of integrated services that they believed increased the uptake and continuation of contraceptive methods. They felt that integrated services enabled them to reach a larger number of female and male patients and in a more efficient way for patients compared to non-integrated services. Availability of FP services in the same place as HIV care also eliminated the need for most referrals, which many providers saw as a barrier for patients seeking FP. Providers reported many challenges to providing integrated services, including the lack of space, time, and sufficient staff, inadequate training, and commodity shortages. Despite these challenges, the vast majority of providers was supportive of FP/HIV integration and found integrated services to be beneficial to HIV-infected patients. Providers' concerns relating to staffing, infrastructure, and training need to be addressed in order to create sustainable, cost-effective FP/HIV integrated service models.

Embedding surveillance into clinical care to detect serious adverse events in pregnancy

Severe maternal complications in pregnancy in sub-Saharan Africa contribute to high maternal mortality and morbidity. Incidence data on severe maternal complications, life-threatening conditions, maternal deaths and birth outcomes are essential for clinical audit and to inform trial design of the types and frequency of expected severe adverse events (SAEs). However, such data are very limited, especially in sub-Saharan Africa. We set up standardized, systematic clinical surveillance embedded into routine clinical care in a rural county hospital in Kenya. Pregnant women and newborns are systematically assessed and investigated. Data are reported using a standardized Maternal Admission Record that forms both the hospital's clinical record and the data collection tool. Integrating clinical surveillance with routine clinical care is feasible and should be expanded in sub-Saharan Africa, both for improving clinical practice and as a basis for intervention studies to reduce maternal and newborn mortality and morbidity where rates are highest.

Global Call to Action: maximize the public health impact of intermittent preventive treatment of malaria in pregnancy in sub-Saharan Africa.

Intermittent preventive treatment of malaria in pregnancy is a highly cost-effective intervention which significantly improves maternal and birth outcomes among mothers and their newborns who live in areas of moderate to high malaria transmission. However, coverage in sub-Saharan Africa remains unacceptably low, calling for urgent action to increase uptake dramatically and maximize its public health impact. The ‘Global Call to Action’ outlines priority actions that will pave the way to success in achieving national and international coverage targets. Immediate action is needed from national health institutions in malaria-endemic countries, the donor community, the research community, members of the pharmaceutical industry and private sector, along with technical partners at the global and local levels, to protect pregnant women and their babies from the preventable, adverse effects of malaria in pregnancy.

Prevalence of HBsAg and knowledge about hepatitis B in pregnancy in the Buea Health District, Cameroon: a cross-sectional study.

BackgroundAlthough infection with Hepatitis B Virus (HBV) remains a global public health problem, little is known about its epidemiology in pregnancy in sub-Saharan Africa. This study sought to determine the prevalence of, and identify factors associated with hepatitis B surface antigen (HBsAg) positivity among pregnant women in the Buea Health District (BHD) in rural Cameroon. We also assessed pregnant women’s knowledge about hepatitis B.MethodsA cross-sectional, descriptive study was undertaken. Participants were evaluated using a structured questionnaire with clinical examination and were then screened for HBsAg using a commercial rapid diagnostic test. Assessment of knowledge was done using a hepatitis B basic knowledge summary score.ResultsOf the 176 pregnant women studied, 9.7% (95% CI: 5.7%, 15%) tested positive for HBsAg. None of the risk factors assessed was significantly associated with HBsAg positivity. The hepatitis B knowledge summary score ranged from 0 to 12 with a mean of 1.5 (SD = 3.14, median = 0, IQR = 0 to 0). Only 16% of participants had scores greater than 6/12. The knowledge summary score of the participants was associated with the educational level (p-value = 0.0037).ConclusionThe high prevalence of HBsAg (9.7%) among women of child bearing age suggests that vertical transmission of HBV may be a public health problem in Buea Health District. Knowledge of HBV among pregnant women was poor. We recommend that all pregnant women ought to be routinely screened for HBV and that health education on HBV should be provided to pregnant women especially during antenatal visits.

Effectiveness of Antenatal Clinics to Deliver Intermittent Preventive Treatment and Insecticide Treated Nets for the Control of Malaria in Pregnancy in Mali: A Household Survey

BackgroundWHO recommends intermittent-preventive-treatment (IPTp) with sulphadoxine-pyrimethamine (SP) and insecticide-treated-nets (ITNs) to prevent malaria in pregnancy in sub-Saharan Africa, however uptake remains unacceptably low. We evaluated the effectiveness of antenatal clinics (ANC) to deliver two doses of IPTp and ITNs to pregnant women in Segou district, Mali.MethodsWe used household data to assess the systems effectiveness of ANC to deliver IPTp and ITNs to pregnant women and used logistic regression to identify predictors of ANC attendance, receipt of IPTp and ITN use during pregnancy, and the impact on community effectiveness.ResultsOf 81% of recently pregnant women who made at least one ANC visit, 59% of these attended during the eligible gestational age for IPTp. Of these, 82% reported receiving one dose of SP and 91% attended ANC again, of whom 66% received a second dose, resulting in a cumulative effectiveness for 2-dose IPTp of 29%, most of whom used an ITN (90%). Cumulative effectiveness of 2-dose SP by directly observed therapy (DOT) was very low (6%). ITN use was 92%, and ANC was the main source (81%). Reported and ANC-card data showed some doses of SP are given to women in their first trimester. Women were less likely to receive two doses by DOT if they were married (OR 0.10; CI 0.03, 0.40), or lived <5 km from the health facility (OR 0.34; CI 0.14, 0.83). A high household person-LLIN ratio predicted low ITN use in pregnant women (OR 0.16; CI 0.04, 0.55).ConclusionOur findings suggest poor adherence by health workers to provision of IPTp by eligible gestational age and DOT, contributing to low effectiveness of this strategy in this setting. ITN delivery and use among women was substantially higher. Efforts to improve health worker adherence to IPTp guidelines are needed to improve service delivery of IPTp.
