Bekele Y, Gallagher C, Vicendese D, Buultjens M, Batra M, Erbas B. The Effects of Maternal Iron and Folate Supplementation on Pregnancy and Infant Outcomes in Africa: A Systematic Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:856. [PMID: 39063433 PMCID: PMC11276896 DOI: 10.3390/ijerph21070856] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 06/13/2024] [Accepted: 06/27/2024] [Indexed: 07/28/2024]
Abstract
BACKGROUND Iron and folate deficiency are prevalent in pregnant women in Africa. However, limited research exists on the differential effect of oral iron-only, folate-only, or Iron Folic Acid (IFA) supplementation on adverse pregnancy and infant outcomes. This systematic review addresses this gap, focusing on studies conducted in Africa with limited healthcare access. Understanding these differential effects could lead to more targeted and potentially cost-effective interventions to improve maternal and child health in these settings. METHODS A systematic review was conducted following PRISMA guidelines. The primary exposures were oral iron-only, folate-only, or IFA oral supplementation during pregnancy, while the outcomes were adverse pregnancy and infant outcomes. A qualitative synthesis guided by methods without meta-analysis was performed. RESULTS Our qualitative synthesis analysed 10 articles reporting adverse pregnancy (adverse birth outcomes, stillbirths, and perinatal mortality) and infant outcomes (neonatal mortality). Consistently, iron-only supplementation demonstrated a reduction in perinatal death. However, evidence is insufficient to assess the relationship between iron-only and IFA supplementation with adverse birth outcomes, stillbirths, and neonatal mortality. CONCLUSION Findings suggested that iron-only supplementation during pregnancy may reduce perinatal mortality in African women. However, evidence remains limited regarding the effectiveness of both iron-only and IFA supplementation in reducing stillbirths, and neonatal mortality. Moreover, additional primary studies are necessary to comprehend the effects of iron-only, folate-only, and IFA supplementation on pregnancy outcomes and infant health in the African region, considering rurality and income level as effect modifiers.

Azaare J, Kolekang AS, Agyeman YN. Maternal health care policy intervention and its impact on perinatal mortality outcomes in Ghana: evidence from a quasi-experimental design. Public Health 2023; 222:37-44. [PMID: 37515835 DOI: 10.1016/j.puhe.2023.06.035] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2022] [Revised: 05/29/2023] [Accepted: 06/26/2023] [Indexed: 07/31/2023]
Abstract
OBJECTIVE This study aimed to evaluate the impact of Ghana's free maternal health care policy on stillbirth and perinatal death since its implementation a decade ago. STUDY DESIGN The study used the propensity score matching method, a quasi-experimental design technique and secondary data to construct two groups of mothers with a history of perinatal deaths who subscribed to the 'free' maternal health care policy versus mothers who did not. METHOD The study merged two rounds of repeated cross-sectional data sets obtained from the Ghana Demographic and Health Survey (GDHS), 2008 and 2014, and generated exposure variables; pregnant women policy holding status and outcome variables; stillbirth and perinatal death by constructing binary outcomes from the under-five mortality variables of the DHS data sets. Fetal and early neonatal deaths within the data set were categorized into two groups: those exposed to the free maternal health care policy and those who did not. The propensity scores of the two groups were then generated and analyzed after checking for bias and common support. The analysis applied sample weighting to account for clustering and stratification due to the complex design of the DHS. All analyses were done with STATA 15 and adjusted for confounding using independent covariates. RESULTS Stillbirth (43.3%) and perinatal death (60.2%) were high in the intervention group compared to the comparison group, and the differences were statistically significant (stillbirth, 0.0156, and perinatal death, 0.0012). Stillbirth and perinatal deaths were 12 and 13 percentage points higher in the intervention group, and these were statistically significant: adj. coef. = 0.12; 95% CI: [0.03-0.19]; P = 0.005 and adj. coef. = 0.13; 95% CI: [0.03-0.22]; P = 0.005. CONCLUSION The results show that stillbirth and perinatal death were high in the maternal health care policy group, poorly reflecting as outcomes. However, the percentage point difference between stillbirth and perinatal death suggests a decline in early neonatal mortality and a positive impact of the 'free' maternal health care policy on perinatal death over stillbirth.

Screening for Resistant Bacteria, Antimicrobial Resistance Genes, Sexually Transmitted Infections and Schistosoma spp. in Tissue Samples from Predominantly Vaginally Delivered Placentae in Ivory Coast and Ghana. Pathogens 2023; 12:999. [PMID: 37623959 PMCID: PMC10459482 DOI: 10.3390/pathogens12080999] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 07/27/2023] [Accepted: 07/28/2023] [Indexed: 08/26/2023] Open
Abstract
Medical complications during pregnancy have been frequently reported from Western Africa with a particular importance of infectious complications. Placental tissue can either become the target of infectious agents itself, such as, e.g., in the case of urogenital schistosomiasis, or be subjected to contamination with colonizing or infection-associated microorganisms of the cervix or the vagina during vaginal delivery. In the retrospective cross-sectional assessment presented here, the quantitative dimension of infection or colonization with selected resistant or pathogenic bacteria and parasites was regionally assessed. To do so, 274 collected placental tissues from Ivory Coastal and Ghanaian women were subjected to selective growth of resistant bacteria, as well as to molecular screening for beta-lactamase genes, Schistosoma spp. and selected bacterial causative agents of sexually transmitted infections (STI). Panton-Valentine-negative methicillin-resistant Staphylococcus aureus (MRSA) was grown from 1.8% of the tissue samples, comprising the spa types t008 and t688, as well as the newly detected ones, t12101 (n = 2) and t12102. While the culture-based recovery of resistant Enterobacterales and nonfermentative rod-shaped Gram-negative bacteria failed, molecular assessments confirmed beta-lactamase genes in 31.0% of the samples with multiple detections of up to four resistance genes per sample and blaCTX-M, blaIMP, blaGES, blaVIM, blaOXA-58-like, blaNDM, blaOXA-23-like, blaOXA-48-like and blaKPC occurring in descending order of frequency. The beta-lactamase genes blaOXA-40/24-like, blaNMC_A/IMI, blaBIC, blaSME, blaGIM and blaDIM were not detected. DNA of the urogenital schistosomiasis-associated Schistosoma haematobium complex was recorded in 18.6% of the samples, but only a single positive signal for S. mansoni with a high cycle-threshold value in real-time PCR was found. Of note, higher rates of schistosomiasis were observed in Ghana (54.9% vs. 10.3% in Ivory Coast) and Cesarean section was much more frequent in schistosomiasis patients (61.9% vs. 14.8% in women without Schistosoma spp. DNA in the placenta). Nucleic acid sequences of nonlymphogranuloma-venereum-associated Chlamydia trachomatis and of Neisseria gonorrhoeae were recorded in 1.1% and 1.9% of the samples, respectively, while molecular attempts to diagnose Treponema pallidum and Mycoplasma genitalium did not lead to positive results. Molecular detection of Schistosoma spp. or STI-associated pathogens was only exceptionally associated with multiple resistance gene detections in the same sample, suggesting epidemiological distinctness. In conclusion, the assessment confirmed considerable prevalence of urogenital schistosomiasis and resistant bacterial colonization, as well as a regionally expected abundance of STI-associated pathogens. Continuous screening offers seem advisable to minimize the risks for the pregnant women and their newborns.

Maternal and neonatal data collection systems in low- and middle-income countries for maternal vaccines active safety surveillance systems: A scoping review. BMC Pregnancy Childbirth 2021; 21:217. [PMID: 33731029 PMCID: PMC7968860 DOI: 10.1186/s12884-021-03686-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Accepted: 03/01/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Most post-licensure vaccine pharmacovigilance in low- and middle-income countries (LMICs) are passive reporting systems. These have limited utility for maternal immunization pharmacovigilance in LMIC settings and need to be supplemented with active surveillance. Our study's main objective was to identify existing perinatal data collection systems in LMICs that collect individual information on maternal and neonatal health outcomes and could be developed to inform active safety surveillance of novel vaccines for use during pregnancy. METHODS A scoping review was performed following the Arksey and O'Malley six-stage approach. We included studies describing electronic or mixed paper-electronic data collection systems in LMICs, including research networks, electronic medical records, and custom software platforms for health information systems. Medline PubMed, EMBASE, Global Health, Cochrane Library, LILACS, Bibliography of Asian Studies (BAS), and CINAHL were searched through August 2019. We also searched grey literature including through Google and websites of existing relevant perinatal data collection systems, as well as contacted authors of key studies and experts in the field to validate the information and identify additional sources of relevant unpublished information. RESULTS A total of 11,817 records were identified. The full texts of 264 records describing 96 data collection systems were assessed for eligibility. Eight perinatal data collection systems met our inclusion criteria: Global Network's Maternal Newborn Health Registry, International Network for the Demographic Evaluation of Populations and their Health; Perinatal Informatic System; Pregnancy Exposure Registry & Birth Defects Surveillance; SmartCare; Open Medical Record System; Open Smart Register Platform and District Health Information Software 2. These selected systems were qualitatively characterized according to seven different domains: governance; system design; system management; data management; data sources, outcomes and data quality. CONCLUSION This review provides a list of active maternal and neonatal data collection systems in LMICs and their characteristics as well as their outreach, strengths, and limitations. Findings could potentially help further understand where to obtain population-based high-quality information on outcomes to inform the conduct of maternal immunization active vaccine safety surveillance activities and research in LMICs.

Associations between Maternal Dietary Patterns and Perinatal Outcomes: A Systematic Review and Meta-Analysis of Cohort Studies. Adv Nutr 2021; 12:1332-1352. [PMID: 33508080 PMCID: PMC8321866 DOI: 10.1093/advances/nmaa156] [Citation(s) in RCA: 38] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Revised: 09/10/2020] [Accepted: 11/10/2020] [Indexed: 02/06/2023] Open
Abstract
The aim was to systematically review and meta-analyze prospective cohort studies investigating the relation between maternal dietary patterns during pregnancy with pregnancy and birth outcomes. PubMed, Scopus, and ISI Web of Science were searched from inception until October 2019 for eligible studies. Studies reporting relative risk, ORs, or incidences (for binary data) or means ± SDs or B-coefficients (for continuous outcomes) comparing the highest and lowest adherence with maternal dietary patterns were included. Dietary patterns were categorized as "healthy," "unhealthy," or "mixed." No language restrictions were applied. Study-specific effect sizes with SEs for outcomes of interest were pooled using a random-effects model. Quality of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Sixty-six relevant publications were included. A higher maternal adherence to a healthy diet was associated with a reduced risk of gestational hypertension (14%, P < 0.001), maternal depression (40%, P = 0.004), low birth weight (28%, P = 0.001), preterm birth (56%, P < 0.001), higher gestational weight gain (Hedges' g: 0.15; P = 0.01), and birth weight (Hedges' g: 0.19; P = 0.007). Higher maternal adherence to an unhealthy or a mixed diet was associated with higher odds of gestational hypertension (23%, P < 0.001 for unhealthy, and 8%, P = 0.01 for mixed diet). In stratified analyses, a higher healthy eating index was associated with reduced odds of being large based on gestational age (31%, P = 0.02) and a higher head circumference at birth (0.23 cm, P = 0.02). The Mediterranean and "prudent" dietary patterns were related to lower odds of being small based on gestational age (46%, P = 0.04) and preterm birth (52%, P = 0.03), respectively. The overall GRADE quality of the evidence for most associations was low or very low, indicating that future high-quality research is warranted. This study was registered at http://www.crd.york.ac.uk/PROSPERO as CRD42018089756.

Abstract
Background Despite decreasing overall perinatal and maternal mortality in high-income countries, perinatal and maternal health inequalities are persisting in Sub Saharan African countries. Therefore, this study aimed to determine the effects size of rates and determinants for perinatal mortality in Sub-Saharan countries. Method The sources for electronic datasets were PubMed, Medline, EMBASE, SCOPUS, Google, Google Scholar, and WHO data Library. Observational studies published in the English language from January 01, 2000, to May 30, 2019 were included. STROBE and JBI tools were used to include relevant articles for this review. We used a Comberehensive Meta-Analysis version 2 software for this analysis. The I2 and Q- statistic values were used to detect the level of heterogeneity. The Kendall’s without continuity correction, Begg and Mazumdar rank correlation and Egger’s linear regression tests were used to detect the existence of significant publication bias (P < 0.10). The effects size were expressed in the form of point estimate and odds ratio with 95% CI (P < 0.05) in the random effect analysis using the trim and fill method. Result Twenty-one articles were included in this review. However, only fourteen studies reported the perinatal mortality rate. Among 14 studies, the observed and adjusted PMR was found to be 58.35 and 42.95 respectively. The odds of perinatal mortality among mothers who had no ANC visits was 2.04 (CI: 1.67, 2.49, P < 0.0001) as compared to those who had at least one ANC visit. The odds of perinatal mortality among preterm babies was 4.42 (CI: 2.83, 6.88, P < 0.0001). In most cases, heterogeneity was not evident when subgroup analyses were assessed by region, study design, and setting. Only perinatal mortality (P < 0.0001), antenatal care (P < 0.046) and preterm births (P < 0.034) showed a relationship between the standardized effect sizes and standard errors of these effects. Conclusion In general, engaging in systematic review and meta-analysis would potentially improve under-represented strategies and actions by informing policy makers and program implementers for minimizing the existing socioeconomic inequalities between regions and nations.

Abstract
BACKGROUND Pregnancy-associated malaria (PAM) has been associated with adverse pregnancy outcomes like preterm birth (PTB) and low birthweight (LBW), which are among the leading causes of infant mortality globally. Rates of PTB and LBW are high in countries with a high burden of malaria. PAM may be a contributing factor to PTB and LBW, but is not well understood. METHODS We conducted a systematic review and meta-analysis of studies examining the relationship between PAM and PTB or LBW using PubMed. The title and abstract of all studies were screened by two reviewers, and the full text of selected studies was reviewed to ensure they met inclusion criteria. Information regarding study characteristics and of PTB and LBW births among women with and without PAM was abstracted for included studies. RESULTS Our search terms yielded 2237 articles, of which 18 met our final inclusion criteria. Eight studies examined associations between PAM and PTB, and 10 examined associations between PAM and LBW (population size ranging from 35 to 9956 women). The overall risk of LBW was 63% higher among women with PAM compared with women without PAM (95% CI = 1.48-1.80) and the risk of PTB was 23% higher among women with PAM compared with women without PAM (95% CI = 1.07-1.41). CONCLUSIONS These results indicate that infection with PAM is associated with PTB and LBW. Further understanding of the pathogenesis of disease and the immunologic changes that occur during pregnancy is essential for reducing the disproportional effects this disease has on this vulnerable population.

Antenatal visits are positively associated with uptake of tetanus toxoid and intermittent preventive treatment in pregnancy in Ivory Coast. BMC Public Health 2019; 19:1467. [PMID: 31694607 PMCID: PMC6836543 DOI: 10.1186/s12889-019-7847-1] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2019] [Accepted: 10/25/2019] [Indexed: 01/02/2023] Open
Abstract
Background Malaria and tetanus infections among pregnant women represent two major public health problems in sub-Saharan Africa. Optimum use of Intermittent preventive treatment in pregnancy (IPTp) with sulfadoxine-pyrimethamine (IPTp-SP) and immunization against tetanus among pregnant women during antenatal care (ANC) visits are recommended strategies to prevent these issues. Despite these recommendations, many women in Africa remain deprived of these cost-effective and life-saving interventions. In this study, we aimed to examine the prevalence of women using these two services, and the association between women’s uptake of IPTp-SP and tetanus toxoid (TT) with antenatal care use in Ivory Coast. Methods This study was based on the fifth round of Multiple Indicator Cluster Survey (MICS 5) conducted in Ivory Coast in 2016. Participants were 9583 women aged between 15 and 49 years. Outcomes were TT and Intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP). Data analysis was conducted using bivariate and multiple logistic regression. Results In this study, the prevalence of taking TT immunization and IPTp-SP drugs was 81.97 and 17.83% respectively. Of the participants who took these drugs at all, the prevalence of taking adequate doses of TT immunization was 78.75% and that of IPTp-SP was 35.46%. In the multivariable analysis model, higher age groups, 25–29 years (OR = 2.028, 95%CI = 1.120–3.669) were found to be positively associated with uptake of adequate doses of IPTp-SP drugs. Women who attended at least four ANC visits had higher odds of taking IPTp-SP drugs (OR = 1.656, 95%CI = 1.194–2.299) and TT immunization (OR = 2.347, 95%CI = 1.384–3.981), and also had higher odds of receiving adequate doses of IPTp-SP drugs (OR = 3.291, 95%CI = 2.157–5.020) and that of TT immunization (OR = 1.968, 95%CI = 1.398–2.771). The odds of taking IPTp-SP drugs were significantly higher among women with primary (OR = 2.504, 95%CI = 1.020–6.146) and secondary/higher education (OR = 3.298, 95%CI = 1.343–8.097) compared to those with no education. Also, women with higher parity had lower odds of taking TT immunization (OR = 0.218, 95%CI = 0.055–0.858) compared to those with lower parity. Findings from this study also revealed that the odds of taking adequate doses of IPTp-SP drugs were significantly lower among participants from Mandé du Nord ethnicity (OR = 0.378,95%CI = 0.145–0.983) compared to those from other ethnicities. Conclusion In this study, uptake of IPTp-SP drugs was much lower than TT immunization. High number of ANC visits were found to be significantly associated with taking IPTp-SP drugs and TT immunization and also with that of taking them in adequate doses. Vaccination promotion is necessary to protect pregnant women and reduce adverse health outcomes among the newborn in Ivory Coast.

PLoS One 2019; 14:e0218163. [PMID: 31260473 PMCID: PMC6602179 DOI: 10.1371/journal.pone.0218163] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Accepted: 05/28/2019] [Indexed: 11/18/2022] Open
Abstract
Background Over the past 15 years, scaling up of cost effective interventions resulted in a remarkable decline of under-five mortality rates (U5MR) in sub-Saharan Africa. However, the reduction shows considerable heterogeneity. We estimated the association of child, maternal, and household interventions with U5MR in Burkina Faso at national and subnational levels and identified the regions with least effective interventions. Methods Data on health-related interventions and U5MR were extracted from the Burkina Faso Demographic and Health Survey (DHS) 2010. Bayesian geostatistical proportional hazards models with a Weibull baseline hazard were fitted on the mortality outcome. Spatially varying coefficients were considered to assess the geographical variation in the association of the health interventions with U5MR. The analyses were adjusted for child, maternal, and household characteristics, as well as climatic and environmental factors. Findings The average U5MR was as high as 128 per 1000 ranging from 81 (region of Centre-Est) to 223 (region of Sahel). At national level, DPT3 immunization and baby post-natal check within 24 hours after birth had the most important association with U5MR (hazard rates ratio (HRR) = 0.89, 95% Bayesian credible interval (BCI): 0.86–0.98 and HRR = 0.89, 95% BCI: 0.86–0.92, respectively). At sub-national level, the most effective interventions are the skilled birth attendance, and improved drinking water, followed by baby post-natal check within 24 hours after birth, vitamin A supplementation, antenatal care visit and all-antigens immunization (including BCG, Polio3, DPT3, and measles immunization). Centre-Est, Sahel, and Sud-Ouest were the regions with the highest number of effective interventions. There was no intervention that had a statistically important association with child survival in the region of Hauts Bassins. Interpretation The geographical variation in the magnitude and statistical importance of the association between health interventions and U5MR raises the need to deliver and reinforce health interventions at a more granular level. Priority interventions are DPT3 immunization, skilled birth attendance, baby post-natal visits in the regions of Sud-Ouest, Sahel, and Hauts Bassins, respectively. Our methodology could be applied to other national surveys, as it allows an incisive, data-driven and specific decision-making approach to optimize the allocation of health interventions at subnational level.

Zanardi DM, Parpinelli MA, Haddad SM, Costa ML, Sousa MH, Leite DFB, Cecatti JG. Adverse perinatal outcomes are associated with severe maternal morbidity and mortality: evidence from a national multicentre cross-sectional study. Arch Gynecol Obstet 2019; 299:645-654. [PMID: 30539385 DOI: 10.1007/s00404-018-5004-1] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2018] [Accepted: 12/04/2018] [Indexed: 01/08/2023]
Abstract
PURPOSE To assess the association between maternal potentially life-threatening conditions (PLTC), maternal near miss (MNM), and maternal death (MD) with perinatal outcomes. METHODS Cross-sectional study in 27 Brazilian referral centers from July, 2009 to June, 2010. All women presenting any criteria for PLTC and MNM, or MD, were included. Sociodemographic and obstetric characteristics were evaluated in each group of maternal outcomes. Childbirth and maternal morbidity data were related to perinatal adverse outcomes (5th min Apgar score < 7, fetal death, neonatal death, or any of these). The Chi-squared test evaluated the differences between groups. Multiple regression analysis adjusted for the clustering design effect identified the independently associated maternal factors with the adverse perinatal outcomes (prevalence ratios; 95% confidence interval). RESULTS Among 8271 cases of severe maternal morbidity, there were 714 cases of adverse perinatal outcomes. Advanced maternal age, low level of schooling, multiparity, lack of prenatal care, delays in care, preterm birth, and adverse perinatal outcomes were more common among MNM and MD. Both MNM and MD were associated with Apgar score (2.39; 1.68-3.39); maternal hemorrhage was the most prevalent characteristic associated with fetal death (2.9, 95% CI 1.81-4.66) and any adverse perinatal outcome (2.16; 1.59-2.94); while clinical/surgical conditions were more related to neonatal death (1.56; 1.08-2.25). CONCLUSION We confirmed the association between MNM and MD with adverse perinatal outcomes. Maternal and perinatal issues should not be dissociated. Policies aiming maternal care should include social and economic development, and improvements in accessibility to specialized care. These, in turn, will definitively impact on childhood mortality rates.
