Determinants and Differentials of Maternal Reproductive Health Outcomes in Nigeria: A Review of National Demographic Health Survey Data from 1999 to 2013

Women in Sub-Saharan Africa face significant clinical and socio-demographic challenges that translate to poor health outcomes including high maternal morbidity and mortality. Nigeria being the most populous nation in Africa bears a significant burden of both communicable and non-communicable diseases. This study aimed to determine the trends and differentials in indices fuelling poor health outcomes in Nigeria. The study was a review and trend analysis of maternal reproductive health indicators obtained from the Nigeria National Demographic and Health Survey (NDHS) data from 1990 to 2013 including secondary data from WHO, UNICEF and the World Bank. The life expectancy at birth was 54.5 years with an estimated infant mortality rate of 75 per 1000 live births, child mortality rate of 88 per 1,000 live births, under-5 mortality rate of 157 per 1,000 live births and a maternal mortality ratio (MMR) of 545 per 100,000 live births. Contraceptive prevalence was 22% among women in the wealthiest quintile and 3% among those in the poorest quintile.  Only 3% of women with no education used modern contraception as compared to 24% of women with tertiary education. Most of the maternal deaths were due to preventable causes which were largely related to poverty, inimical socio-cultural beliefs and practices as well as clinical factors like haemorrage, hypertension, and indirect causes like inadequate human resource for health, user charges, cultural pregnancy/childbirth beliefs and myths. A community-based participatory research using both qualitative and quantitative methods may shed more light on the non-clinical factors fueling high MMR in Nigeria.

Childbirth Practices in the Akpabuyo Rural Health and Demographic Surveillance System

Maternal and neonatal mortality remain high in Nigeria. The State and Federal governments have adopted several strategies to prevent maternal and infant deaths such as the Cross River State Free Health Services to pregnant women and infants, and the National Midwives’ Service Scheme. This study assessed pregnancy and childbirth practices of Nigerian women in rural communities located in Akpabuyo in the Niger Delta region of Nigeria. Women who were pregnant or had recently given birth in a population of 5,668 people under surveillance in some rural communities of Akpabuyo were interviewed to obtain information on pregnancy and childbirth practices. Validated semi-structured questionnaires were administered by well-trained field workers. Completed questionnaires were entered into electronic data forms in OpenHDS software and exported to STATA for analysis. Results showed that, 39.5% of women reported that they had sought prenatal care from a traditional birth attendant (TBA). 84.6% of all births occurred outside the formal health system with the majority attended by TBAs. Only 15.4% of births occurred in hospitals or health centres. The implements used to cut the umbilical cord were knives (46.2%), new razor blades, old razor blades, sharp stone and scissors. The materials used for treating the umbilical cord were mostly methylated spirit (63.1%); other treatment materials were“western medicine”, “black powder” and others including herbs and earth. The study concluded that, childbirth practices that pose significant risk to maternal and newborn health remain common in these rural communities. Majority of births were attended by TBAs despite free delivery services available at the formal health facilities. TBAs should be assisted to enhance their role in health care delivery. Effort should be made to increase public awareness and interest in facility-based services. Keywords: Maternal health, neonatal infection, longitudinal data, pregnancy

Optimum hardware, software and personnel requirements for a paperless health and demographic surveillance system: a case study of Cross River HDSS, Nigeria

Health and Demographic Surveillance Systems (HDSS) are a robust and rigorous data collection, validation, storage, analysis and reporting platforms for community-based data on vital events. These processes make high demands on paper and man-hours with attendant implications on running costs and environmental impact. However, with the rapid development of ICT and increasing affordability of computing devices, some of the manual processes can be replaced with ICT tools. This paper presents a case study of the Cross River HDSS in Akpabuyo Southern Nigeria with a view to highlighting the essential personnel, hardware and software requirements for running an IT-based paperless HDSS in low income settings. The DSA comprised of 22 contiguous EAs of 1370 households. The case study entailed four update rounds, each of which involved field workers visiting households and obtaining information on vital events. The first update round was purely paper-based involving the use of large collections of paper forms for interviews. The last three rounds were IT-based, devoid of paper questionnaires and ran on web-based open source software. Hardware was a set of high-end servers, desktops, tablet PCs and android phones for data collection.   The case study demonstrated the feasibility of running a paperless IT-based HDSS in a resource-poor setting using free and open source software, such as the web-based OpenHDS, MySQL, ODK, MirthConnect, etc. This overcomes the limitations of the popular HRS2 in terms of costs, complexities, and lack of compatibility with changing hardware and system software configurations. However, running IT-based paperless HDSS threw up some challenges, such as cases of poor internet connectivity, absence of GSM network connectivity using mobile devices, and having the right mix of staff with sufficient IT skills. This paper recommended solution strategies for overcoming these challenges. The need for the development of new set of protocols for data quality in a paperless HDSS is also discussed.   Keywords: Health, demographic surveillance system, information technology, paper, environment, enumeration area

Can Africa achieve herd immunity?

The World Health Organization described herd immunity, also known as population immunity, as the indirect fortification from an infectious disease that happens when a population is immune either through vaccination or immunity developed through previous exposure to infection. The emergence of COVID-19 vaccine is a step towards the achievement of herd immunity. Over one billion people across the globe have been vaccinated and Africa recorded only 2%. The objective of this article was to develop a forecast of the number of people to be vaccinated to achieve herd immunity in the 13 WHO-identified priority African countries for COVID-19. Herd immunity is achieved when one infected person in a population causes less than one secondary case on average, corresponding to the effective basic reproduction number (R0). Vaccine delivery and distribution infrastructure including the cold chain remains weak. Vaccine hesitancy is also one of the limiting factors that may hinder herd immunity in Africa. In order to achieve herd immunity globally, African countries should not be excluded in fair and equal distribution of vaccines. Relevant stakeholders should foster commitment as well as community sensitization on COVID-19 vaccines and integration of COVID-19 vaccines in existing healthcare services

Impact of COVID-19 pandemic on antenatal healthcare services in Sub-Saharan Africa

Many Sub-Saharan African countries have been known to suffer various challenges which threaten the quality of health services that are offered to the population. With the emergence of COVID-19 outbreak, it is not impossible that access to quality antenatal care services would be further threatened in the region due to the competition for limited health care resources. This paper seeks to highlight the impact of COVID-19 pandemic on antenatal healthcare services in Sub-Saharan Africa. It is imperative for all African countries to put up measures to ensure antenatal care services, which are just as important and needed, are not disrupted due to the urgent need to shift limited resources to contain the COVID-19 pandemic

Malariometric indices among Nigerian children in a rural setting

Malaria contributes to high childhood morbidity and mortality in Nigeria. To determine its endemicity in a rural farming community in the south-south of Nigeria, the following malariometric indices, namely, malaria parasitaemia, spleen rates, and anaemia were evaluated in children aged 2-10 years. This was a descriptive cross-sectional survey among school-age children residing in a rubber plantation settlement. The children were selected from six primary schools using a multistaged stratified cluster sampling technique. They were all examined for pallor, enlarged spleen, or liver among other clinical parameters and had blood films for malaria parasites. Of the 461 children recruited, 329 (71.4%) had malaria parasites. The prevalence of malaria parasitaemia was slightly higher in the under fives than that of those ≥5 years, 76.2% and 70.3%, respectively. Splenic enlargement was present in 133 children (28.9%). The overall prevalence of anaemia was 35.7%. Anaemia was more common in the under-fives (48.8%) than in those ≥5 years (32.8%). The odds of anaemia in the under fives were significantly higher than the odds of those ≥5 years (OR = 1.95 [1.19-3.18]). Malaria is highly endemic in this farming community and calls for intensification of control interventions in the area with special attention to school-age children

Oral hygiene practices and utilization of oral healthcare services among in-school adolescents in Calabar, Cross River State, Nigeria

Introduction: oral health mirrors an individual´s general health, hence, proper care should be taken to prevent oral diseases and conditions. An estimated 3.9 billion people worldwide are affected by oral conditions, and adolescents are at increased risk due to diet choices and hormonal changes. This study aimed at determining the oral hygiene practices, awareness and utilization of oral healthcare services among in-school adolescents in Calabar Municipality. Methods: a descriptive cross-sectional study design was employed in studying these variables among in-school adolescents (10-19 years) in secondary schools (JSS1-SSS2) using a self-administered, semi-structured questionnaire. Data were entered and analyzed with EPI-Info. Cross tabulations of variables were conducted using Chi-square test with significance level of 5%. Results: a total of 335 students participated in the study with 228 (68.1%) and 136 (40.6%) reporting that they are aware of and have utilized oral healthcare services (OHS), respectively. There was no statistically significant association between age (p=0.923), gender (p=0.351) and type of school (p=0.497) respectively with awareness and utilization of OHS. Toothache/pain and presumed good dental health respectively were the main reasons for the usage and non-utilization of these services. Time-to-use of oral health services after the onset of toothache/pain was within five days (75.7%). Conclusion: the utilization rate of OHS did not match up to the level of awareness of these services with pain being the main driver for utilization. Increased awareness of oral healthcare through health education and oral healthcare demonstrations among adolescents is highly recommended as part of school health programs

Emergency transportation interventions for reducing adverse pregnancy outcomes in low- and middle-income countries: a systematic review protocol

Transportation interventions seek to decrease delay in reaching a health facility for emergency obstetric care and are, thus, believed to contribute to reductions in such adverse pregnancy and childbirth outcomes as maternal deaths, stillbirths, and neonatal mortality in low- and middle-income countries (LMICs). However, there is limited empirical evidence to support this hypothesis. The objective of the proposed review is to summarize and critically appraise evidence regarding the effect of emergency transportation interventions on outcomes of labor and delivery in LMICs. The following databases will be searched from inception to March 31, 2018: MEDLINE/PubMed, EMBASE, Web of Science, EBSCO (PsycINFO and CINAHL), the Cochrane Pregnancy and Child Birth Group's Specialized Register, and the Cochrane Central Register of Controlled Trials. We will search for studies in the grey literature through Google and Google Scholar. We will solicit unpublished reports from such relevant agencies as United Nations Fund for Population Activities (UNFPA), the World Health Organization (WHO), the United Nations Children's Fund (UNICEF), the United States Agency for International Development (USAID), and the United Kingdom Department for International Development (DfID) among others. Data generated from the search will be managed using Endnote Version 7. We will perform quantitative data synthesis if studies are homogenous in characteristics and provide adequate outcome data for meta-analysis. Otherwise, data will be synthesized, using the narrative synthesis approach. Among the many barriers that women in LMICs face in accessing life-saving interventions during labor and delivery, lack of access to emergency transportation is particularly important. This review will provide a critical summary of evidence regarding the impact of transportation interventions on outcomes of pregnancy and childbirth in LMICs.

Intermittent preventive treatment for malaria in children living in areas with seasonal transmission

Background In malaria endemic areas, pre-school children are at high risk of severe and repeated malaria illness. One possible public health strategy, known as Intermittent Preventive Treatment in children (IPTc), is to treat all children for malaria at regular intervals during the transmission season, regardless of whether they are infected or not. Objectives To evaluate the effects of IPTc to prevent malaria in preschool children living in endemic areas with seasonal malaria transmission. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register (July 2011), CENTRAL (The Cochrane Library 2011, Issue 6), MEDLINE (1966 to July 2011), EMBASE (1974 to July 2011), LILACS (1982 to July 2011), mRCT (July 2011), and reference lists of identified trials. We also contacted researchers working in the field for unpublished and ongoing trials. Selection criteria Individually randomized and cluster-randomized controlled trials of full therapeutic dose of antimalarial or antimalarial drug combinations given at regular intervals compared with placebo or no preventive treatment in children aged six years or less living in an area with seasonal malaria transmission. Data collection and analysis Two authors independently assessed eligibility, extracted data and assessed the risk of bias in the trials. Data were meta-analysed and measures of effects (ie rate ratio, risk ratio and mean difference) are presented with 95% confidence intervals (CIs). The quality of evidence was assessed using the GRADE methods. Main results Seven trials (12,589 participants), including one cluster-randomized trial, met the inclusion criteria. All were conducted in West Africa, and six of seven trials were restricted to children aged less than 5 years. IPTc prevents approximately three quarters of all clinical malaria episodes (rate ratio 0.26; 95% CI 0.17 to 0.38; 9321 participants, six trials, high quality evidence), and a similar proportion of severe malaria episodes (rate ratio 0.27, 95% CI 0.10 to 0.76; 5964 participants, two trials, high quality evidence). These effects remain present even where insecticide treated net (ITN) usage is high (two trials, 5964 participants, high quality evidence). IPTc probably produces a small reduction in all-cause mortality consistent with the effect on severe malaria, but the trials were underpowered to reach statistical significance (risk ratio 0.66, 95% CI 0.31 to 1.39, moderate quality evidence). The effect on anaemia varied between studies, but the risk of moderately severe anaemia is probably lower with IPTc (risk ratio 0.71, 95% CI 0.52 to 0.98; 8805 participants, five trials, moderate quality evidence). Serious drug-related adverse events, if they occur, are probably rare, with none reported in the six trials (9533 participants, six trials, moderate quality evidence). Amodiaquine plus sulphadoxine-pyrimethamine is the most studied drug combination for seasonal chemoprevention. Although effective, it causes increased vomiting in this age-group (risk ratio 2.78, 95% CI 2.31 to 3.35; two trials, 3544 participants, high quality evidence). When antimalarial IPTc was stopped, no rebound increase in malaria was observed in the three trials which continued follow-up for one season after IPTc
