Background: Malaria in pregnancy control interventions have been implemented through antenatal care services for more than 2 decades in Ghana. The uptake of these interventions has seen steady improvement over the years. This has occurred within the context of decreasing global trends of malaria infection confirmed by decreasing malaria in pregnancy prevalence in Ghana. However, not much is known about how these improvements in interventions uptake and reduction in malaria infection prevalence have impacted pregnancy outcomes in the country. This study aimed at describing trends of maternal anaemia and low birth weight prevalence and uptake of malaria in pregnancy control interventions over the last decade using data from Ghana’s District Health Information Management System (DHIMS II). Methods: Data from Ghana’s DHIMS II on variables of interest covering the period 2012 to 2021 was analysed descriptively using Microsoft Excel 365. Results were computed as averages and percentages and presented in tables and graphs. Results: The prevalence of maternal anaemia at booking and at term and low birth weight increased marginally from 31.0%, 25.5% and 8.5% in 2012 to 36.6%, 31.9% and 9.5% in 2021 respectively. Severe anaemia prevalence at booking and at term remained under 2% over the study period. Women making at least 4 ANC visits, receiving at least 3 doses of intermittent preventive treatment of malaria and an insecticide-treated net increased from 77.0%, 41.4% and 4.1% in 2012 to 82%, 55.0% and 93.3% in 2021, respectively. Malaria test positivity rate reduced from 54.0% to 34.3% between 2014 and 2021 while women receiving iron and folate supplementation for 3 and 6 months rose from 43.0% and 25.5% to 89.7% and 61.8%, respectively between 2017 and 2021. Conclusion: Maternal anaemia and low birth weight prevalence showed marginal upward trends over the last decade despite reduced malaria infection rate and improved uptake of malaria in pregnancy control interventions. There is room for improvement in current intervention implementation levels but the complex and multi-factorial aetiologies of maternal anaemia and low birth weight need urgent investigation and quantification to inform policy and practice.
This was a descriptive study utilizing secondary data from Ghana’s DHIMS II database over a 10-year period from 2012 to 2021. DHIMS II is an integrated internet-based electronic database of aggregated health facility-based data on health services provided nation-wide [35]. Ghana, a sub-Saharan African country located in West Africa, has a total population of 30.8 million; 50.7% females and a total fertility rate of 3.745 births per woman [36]. It is endemic for malaria, being the leading cause of outpatient health facility visits. Malaria accounted for 34% of all cases seen at the Outpatient’s Department (OPD), 19%% of admissions and 2% of total deaths with pregnant women constituting 3.9% of total suspected cases of malaria reported to the OPD in 2017 [37]. The country is divided into three malaria epidemiological zones with varying transmission intensities; the northern Guinea savannah zone covering the northern regions of Ghana with intense and seasonal transmission (and some pockets of perennial transmission in areas of irrigation projects), the transitional forest zone in the middle of the country with perennial and intense transmission and the coastal savannah zone along the coast of the Atlantic Ocean [33, 38]. Malaria infection in pregnancy is highest in the northern Guinea zone, followed by the middle transitional zone and lowest in the coastal savannah zone [33]. There are currently 16 administrative regions, the last 6 being couched from bigger regions in 2018. Each region is divided into metropolitan areas, municipalities or districts depending on population sizes. For health services, metropolitan areas, municipalities and districts are further subdivided into sub-metropolitan areas, sub-municipalities and sub-districts. The regions, metropolis/municipalities/districts and sub-metropolis/sub-municipalities/sub-districts are managed by Regional, Metropolitan/Municipal/District and Sub-metropolitan/Sub-municipal/Sub-district Health Management teams, representatives of the GHS to enhance delivery, supervision and reporting of health services. Health services are delivered through tertiary level (teaching hospitals), secondary level (regional hospitals) and primary level (district/municipal hospitals, health centres and Community-based health planning services (CHPS) compounds) facilities. The health facilities are mostly public but are supported by private, faith-based, traditional and alternative service providers [35]. At all the health facilities (primary to tertiary), primary data of maternal health services is captured manually into paper-based registers, forms and books which are then summarized monthly onto nationally pre-designed forms for further imputing into the DHIMS II data-base either at the district or sub-district level [39]. This enables timely access to health information by health managers and policy makers at the health facility, district, regional and national levels for tracking progress of health service delivery to inform adequate planning, monitoring and evaluation purposes. Formal permission was sought from the GHS to use the DHIMS II data regarding maternal health services. Based on the aim of this study and availability of data, variables of interest for which data was extracted into an excel spreadsheet included yearly total numbers of: The data obtained from the DHIMS II was analysed descriptively and presented as averages and percentages in tables and graphs, first for the whole country and then per zones using Microsoft Excel 365. The regions of Ghana were grouped into three geographical zones to mimic the ecological and malaria epidemiological zones [33, 38] as follows: Northern/savannah zone comprised of the Upper West, Upper East, North East, Northern and Savannah regions; Middle/forest zone comprised of Bono East, Brong Ahafo, Ahafo, Ashanti, Eastern, Western North and Oti regions and the Southern/coastal zone comprised of the Western, Central, Greater Accra and the Volta regions. Per the definitions in Table Table22 below, the various indicators for the years under review were computed. The total number of expected pregnancies was computed as 4% of the estimated yearly population size of Ghana [40]. The country-wide trends over the 10-year period for anaemia and severe anaemia at booking and at 36 weeks gestation, total LBW prevalence and by primiparous and multiparous women; uptake of IPTp-SP and HIV and syphilis infection prevalence were depicted graphically (values in Additional file 1: Table S1) while those for number of ANC visits, IFA supplementation, ITN distribution and malaria test positivity rate were presented in a table. The trends in anaemia, LBW and IPTp-SP uptake were further analysed at geographical zone level, compared with the national averages and depicted graphically or in a table (values in Additional file 1: Table S2).
