Use of Intermittent Preventive Treatment among Pregnant Women in Sub-Saharan Africa: Evidence from Malaria Indicator Surveys

Determinants of the optimal uptake of sulfadoxine-pyrimethamine doses for intermittent treatment of malaria in pregnancy in urban Nigeria

Malaria is a leading cause of maternal and child mortality in urban Nigeria. Intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP) during pregnancy can prevent malaria but uptake is suboptimal. This cross-sectional study analyzed secondary data on 1159 urban Nigerian women from the 2015 Malaria Indicator Survey using descriptive statistics and logistic regression. The primary outcome was optimal IPTp-SP uptake (≥ 3 doses). 67% of women took any SP during pregnancy but only 39% took ≥ 3 IPTp-SP doses as recommended. Region and wealth index significantly predicted optimal IPTp-SP uptake while education did not. Women from lower-income regions in the urban areas were less likely to receive optimal IPTp-SP. Strategies to increase IPTp-SP uptake in urban Nigeria should target low-income regions and women of lower socioeconomic status. Logistic regression identified actionable factors for improving antenatal malaria prevention. Optimal IPTp-SP uptake remains suboptimal across urban Nigeria, threatening maternal and child health.

The readiness of malaria services and uptake of intermittent preventive treatment in pregnancy in six sub-Saharan countries

Background

Malaria infection during pregnancy is associated with an increased risk of maternal death, as well as adverse birth outcomes. Intermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) is known to improve pregnancy outcomes. However, the coverage of IPTp-SP in antenatal care (ANC) in sub-Saharan Africa remains well below the target. This study aims to estimate to what extent malaria service readiness affects the uptake of IPTp-SP during ANC visits in sub-Saharan African countries.

Methods

This study included 3267 pregnant women attending ANC for the first time and 2797 pregnant women who had attended ANC more than a month ago in six sub-Saharan African countries. The readiness of malaria services at each institution includes four indicators: the presence of IPTp-SP guidelines, SP availability, integration of IPTp-SP service into ANC, and provider training on IPTp-SP. The outcome variable indicates whether a pregnant woman received IPTp-SP at her current ANC visit. A modified Poisson regression model estimated the associations between malaria service readiness and IPTp-SP uptake for women eligible for the first and subsequent doses.

Results

For women eligible for their first dose, visiting an institution with available SP was associated with an increased probability of receiving IPTp-SP (risk ratio (RR) = 1.43; 95% confidence interval (CI) = 1.22 to 1.67, P < 0.001). For women who were eligible for their next dose, the availability of SP (RR = 1.17; 95% CI = 1.04 to 1.32, P = 0.008) and integration of IPTp-SP service into ANC (RR = 1.82; 95% CI = 1.21 to 2.74, P = 0.004) in the institution were associated with increased likelihood of IPTp-SP uptake. Counterfactual predictions indicated that enhanced provider training could boost IPTp-SP uptake in high-uptake countries, while better SP availability and IPTp-SP integration into ANC would significantly impact low-uptake countries.

Conclusions

For better IPTp-SP coverage, strategies should be customised. High uptake countries should focus on provider training, while low uptake ones should ensure IPTp-SP availability and service integration.

Experiences of young mothers with the uptake of Sulfadoxine-Pyrimethamine for intermittent preventive treatment of malaria in pregnancy: a cross-sectional study in the Lake endemic region, Kenya

Background

A substantial proportion of the world population is affected by malaria with 241 million malaria cases reported globally. Intermittent Preventive Treatment in pregnancy (IPTp) with Sulfadoxine-Pyrimethamine (SP) is an effective chemotherapy but its utilisation has not been optimised. Few studies focus on young mothers and their experiences regarding the optimal uptake of IPTp-SP.

Methods

The study design was cross-sectional with data derived from six focus group discussions with mothers aged 15-24 years who had a pregnancy and gave birth to a live baby within the last two years in Kisumu and Migori counties, Kenya. Inductive analysis was used to identify themes and patterns.

Results

Young mothers were motivated to take IPTp-SP during pregnancy if they had prior knowledge about SP and its associated benefits and if they were knowledgeable about the consequences of malaria infection during pregnancy. Perceived side effects of SP, lack of awareness of SP as a malaria prevention therapy, lack of knowledge on the benefits of SP, dosage and frequency of uptake, poor communication by health providers towards young mothers, and inconsistent supply of SP at health facilities inhibited young mothers from attaining the recommended 3+ doses of IPTp-SP.

Conclusions

There is a need for health literacy programmes that focus on increasing knowledge of IPTp-SP dosage, timing and benefits for both the young pregnant mother and her foetus. Community engagement through dialogue with mentor mothers and male partners will be an important complementary approach in establishing a support system for young women for positive health outcomes including attaining the recommended 3+ doses of IPTp-SP.

Socioeconomic and geographical inequalities in health care coverage in Mozambique: a repeated cross-sectional study of the 2015 and 2018 national surveys

BACKGROUND

Over the past years, Mozambique has implemented several initiatives to ensure equitable coverage to health care services. While there have been some achievements in health care coverage at the population level, the effects of these initiatives on social inequalities have not been analysed.

OBJECTIVE

The present study aimed to assess changes in socioeconomic and geographical inequalities (education, wealth, region, place of residence) in health care coverage between 2015 and 2018 in Mozambique.

METHODS

The study was based on repeated cross-sectional surveys from nationally representative samples: the Survey of Indicators on Immunisation, Malaria and HIV/AIDS in Mozambique (IMASIDA) 2015 and the 2018 Malaria Indicator survey. Data from women of reproductive age (15 to 49 years) were analysed to evaluate health care coverage of three indicators: insecticide-treated net use, fever treatment of children, and use of Fansidar malaria prophylaxis for pregnant women. Absolute risk differences and the slope index of inequality (SII) were calculated for the 2015 survey period and the 2018 survey period, respectively. An interaction term between the socioeconomic and geographical variables and the period was included to assess inequality changes between 2015 and 2018.

RESULTS

The non-use of insecticide-treated nets dropped, whereas the proportion of women with children who were not treated for fever and the prevalence of women who did not take the full Fansidar dose during pregnancy decreased between 2015 and 2018. Significant reductions in the inequality related to insecticide-treated net use were observed for all socioeconomic variables. Concerning fever treatment, some reductions in socioeconomic inequalities were observed, though not statistically significant. For malaria prophylaxis, the SII was significant for education, wealth, and residence in both periods, but no significant inequality reductions were observed in any of these variables over time.

CONCLUSIONS

We observed significant reductions of socioeconomic inequalities in insecticide-treated net use, but not in fever treatment of children and Fansidar prophylaxis for pregnant women. Decision-makers should target underserved populations, specifically the non-educated, poor, and rural women, to address inequalities in health care coverage.

Improving coverage of antenatal iron and folic acid supplementation and malaria prophylaxis through targeted information and home deliveries in Côte d'Ivoire: a cluster randomised controlled trial

INTRODUCTION

Coverage of antenatal iron and folic acid (IFA) supplementation and malaria chemoprophylaxis remains low in many low-income and middle-income settings. We assessed the effectiveness of personal information (INFO) sessions and personal information session plus home deliveries (INFO+DELIV) to increase coverage of IFA supplementation and intermittent preventive treatment in pregnancy (IPTp), and their effectiveness on postpartum anaemia and malaria infection.

METHODS

We included 118 clusters randomised to a control (39), INFO (39) and INFO+DELIV (40) arm, in a trial conducted between 2020 and 2021 with pregnant women (age ≥15 years) in their first or second trimester of pregnancy in Taabo, Côte d'Ivoire. We used generalised linear regression models to assess intervention impact in postpartum anaemia and malaria parasitaemia, and displayed resulting estimates as prevalence ratios.

RESULTS

Overall, 767 pregnant women were enrolled and 716 (93.3%) were followed up after delivery. Neither intervention had an impact on postpartum anaemia, with estimated adjusted prevalence ratios (aPRs) of 0.97 (95% CI 0.79 to 1.19, p=0.770) for INFO and 0.87 (95% CI 0.70 to 1.09, p=0.235) for INFO+DELIV. While INFO had no effect on malaria parasitaemia (aPR=0.95, 95% CI 0.39 to 2.31, p=0.915), INFO+DELIV reduced malaria parasitaemia by 83% (aPR=0.17, 95% CI 0.04 to 0.75, p=0.019). No improvements in antenatal care (ANC) coverage (aPR=1.05, 95% CI 0.81 to 1.36, p=0.692), IFA (aPR=2.00, 95% CI 0.89 to 4.46, p=0.093) and IPTp (aPR=1.03, 95% CI 0.87 to 1.21, p=0.728) compliance were found for INFO. INFO+DELIV increased ANC attendance (aPR=1.35, 95% CI 1.02 to 1.78, p=0.037) and compliance with IPTp (aPR=1.60, 95% CI 1.41 to 1.80, p<0.001) and IFA recommendations (aPR=7.06, 95% CI 3.68 to 13.51, p<0.001).

CONCLUSIONS

INFO+DELIV can substantially increase compliance with IFA supplementation and improve malaria prevention. However, the increases in IFA supplementation are likely insufficient to address the prevalence of often severe anaemia in this population.

Are rural pregnant women disadvantaged in accessing intermittent preventive treatment in pregnancy in Ebonyi State, Nigeria?

Introduction

Adequate intermittent preventive treatment (IPTp) uptake (≥3 doses) routinely delivered at antenatal clinics is effective in preventing malaria during pregnancy. Whereas, low IPTp uptake (24.0%) had been reported among pregnant women in Ebonyi State, there is paucity of studies comparing the uptake and its predictors in the urban and rural areas of Ebonyi State. We determined IPTp uptake and its predictors in the urban and rural areas of Ebonyi State.

Methods

We conducted a cross-sectional comparative study among 864 reproductive age women selected using multistage sampling. Using a structured interviewer-administered questionnaire, we collected data on respondent’s socio-demographic characteristics and IPTp uptake. Uptake was adjudged adequate if ≥3 doses were taken, otherwise inadequate. We estimated the proportion of women with adequate IPTp uptake and determined the factors associated with adequate uptake in rural and urban areas using chi square and multiple logistic regression at 5% level of significance.

Results

The mean ages of respondents in the urban and rural areas were 28.5±4.6 and 27.4±5.0 years respectively. Adequate IPTp uptake was 82.5% and 60.8% in the urban and rural respectively (p<0.001). In the urban area, women whose husbands had attained ≥ secondary education (aOR:2.9; 95%CI:1.2–7.4; p = 0.02) and those who paid for sulfadoxine/pyrimethamime (aOR:0.2; 95%CI: 0.1–0.6; p = 0.01) were 2.9 times more likely and 5 times less likely to take adequate IPTp respectively compared to respondents whose husbands had attained ≤ primary education and those who had sulfadoxine/pyrimethamine free. In the rural area, women who had attended ANC <4 times (aOR:0.4; 95%CI: 0.3–0.7; p<0.001) were 2.5 times less likely to take adequate IPTp compared to women that had attended ANC ≥4 times.

Conclusion

Uptake of IPTp was more in the urban than rural areas of Ebonyi State. Interventions that reinforce the importance of health professionals carrying out actions aimed at pregnant women and their partners (spousal) in order to guide them on preventive actions against malaria and other diseases are recommended in Ebonyi State.

Prevalence, determinants and attitude towards herbal medicine use in the first trimester of pregnancy in Cameroon: A survey in 20 hospitals

To examine the prevalence, determinants and attitude towards herbal medication (HM) use in the first trimester of pregnancy in Cameroon women. Between March to August 2015, we surveyed 795 pregnant women attending 20 randomly selected urban or rural hospitals in South West Cameroon on first trimester orthodox medication (OM) and HM use. Data was obtained by interviews using structured questionnaires. First trimester HM use was reported by 293 (36∙9%) women, 76% of whom used it in combination with OM. The most frequent indication for taking HM was prevention/treatment of anaemia (26∙3%). The HM were usually self-prescribed (33∙3%) or by family (56∙2%), and obtained from the woman's own garden (69∙3%). Twenty percent of women believed that HM was always safe to take in pregnancy, compared to 69.3% for OM. Intake of HM was significantly influenced by women's opinion on OM or HM safety-the odds of taking HM was 3 time higher among women who were unsure about the safety of OM (AOR: 3∙0, 95%CI = 1∙5-6∙1), while women who thought HM were never safe or who were unsure about its safety, were 91% or 84% respectively less likely to take HM compared to women who believed HM were always safe. We identified a high prevalence of HM use and concomitant use with OM, strongly influenced by women's perception of HM and OM safety. These findings indicate the need for WHO to specifically address safety in pregnancy in its policy to integrate traditional medicine use into existing healthcare systems in Africa.

Retrospective evaluation of referral by community health workers on the uptake of intermittent preventive treatment of Malaria in pregnancy in Ohaukwu, Ebonyi State, Nigeria

Background

The World Health Organization recommends a minimum of three doses of quality-assured sulfadoxine-pyrimethamine for intermittent preventive treatment of malaria during pregnancy (IPTp), in moderate to high malaria transmission areas in sub-Saharan Africa. Currently, coverage of IPTp lags behind coverage of antenatal care (ANC) visits; in Nigeria, 57% of women attended four or more ANC visits, whereas only 17% received the recommended three or more doses of IPTp. The innovative program aimed to close this gap by providing counseling on the benefits of comprehensive ANC, referral to ANC and community distribution of IPTp (C-IPTp), complementing IPTp at ANC. The study aimed to examine whether CHW referral to ANC improved the likelihood of receiving three or more doses of IPTp.

Methods

The data for this study were extracted from the maternity record books of 1437 pregnant women seen at 25 public health facilities in Ebonyi State, Nigeria. The outcome of interest was defined as the receipt of three or more doses of IPTp (IPTp3) and the independent variable was referral to ANC by a community health worker for any visit. Descriptive statistics were reported and the results from the multi-level regressions are reported as adjusted odds and prevalence ratios with corresponding 95% confidence intervals.

Results

Of the 936 women included in the analysis, 24.47% received the recommended three or more IPTp doses and 61.32% were referred by a community health worker (CHW) for at least one ANC visit. There was no difference in the mean number of ANC visits between women who received C-IPTp and those who received IPTp exclusively at a facility (2.40 vs 2.52; p = 0.374). There were no maternal characteristics associated with CHW referral. Women who were referred by a CHW had 60% greater odds (95% CI, 1.08–2.38) of receiving IPTp3 than those who were never referred.

Conclusion

The results indicate that CHW referrals conducted within a C-IPTp program are associated with higher IPTp uptake but not fewer ANC visits and that CHWs applied the referral process equally. This strengthens the evidence base for C-IPTp scale-up, which could have a large impact in sub-Saharan Africa in mitigating existing health systems issues.

Prevalence and risk factors of malaria and anaemia and the impact of preventive methods among pregnant women: A case study at the Akatsi South District in Ghana

Aim

This study aimed to ascertain the prevalence and risk factors of malaria and anaemia as well as the impact of preventive methods among pregnant women at the Akatsi South District Hospital of Ghana.

Subjects and methods

A hospital based cross-sectional study using simple random sampling technique was conducted among 200 pregnant women receiving antenatal care and laboratory services at the Akatsi District Hospital from May 2016 to July 2016. A semi-structured questionnaire was administered to obtain participants’ malaria preventive methods in addition to demographic and gestational details. Participants’ hemoglobin and malaria status were assessed using one milliliter (1 ml) whole blood collected from each participant following standard procedures. Factors that produced a p-value of ≤0.2 from the univariate model were included in the final model. Association between potential covariates and the outcomes was assessed using multivariate logistic regression. The Clopper-Pearson test statistic was used to determine the 95% confidence intervals of the outcome variables of interest. We also estimated the population attributable fraction (PAF) of anaemia due to malaria by substituting the adjusted relative risk estimates (RR_i) (using the adjrr command in STATA) of anaemia due to malaria into the category-specific attributable formula. P-values of <0.05 were considered statistically significant.

Results

Prevalence of anaemia in pregnancy (AiP), malaria in pregnancy (MiP) and AiP/MiP comorbidity was 63.5% (95% CI:56.4–70.2), 11.0% (96% CI:7.0–16.2) and 10.5% (95% CI:6.6–15.6) respectively. Prevalence rates of AiP (66.7%) and MiP (18.5%) predominated among pregnant women aged < 20 years. PAF of AiP due to MiP was 34.5% (95% CI:23.8–43.6). High use of IPTp-SP, 64.0% (95% CI:56.9–70.6) and LLIN, 90.0% (95% CI:85.0–93.8) was observed in this study. Only 42.0% (95% CI:35.1–49.2) used repellent. Not being on the IPTp-SP program posed a 11.70 times risk of MiP (95% CI:2.32–58.96; p = 0.003) compared to pregnant women on the IPTp-SP program. Similarly, not sleeping under LLIN posed an 8.07 times risk of MiP (95% CI:1.98–32.2; p = 0.004) compared to pregnant women who slept under LLIN. Meanwhile, being positive for MiP posed a 12.10 times risk (95% CI:1.35–85.06; p = 0.025) of AiP compared to those negative for malaria whereas failure to attend ANC as scheduled posed 6.34 times risk (95% CI:1.81–22.19; p = 0.004) of AiP among the pregnant women studied.

Conclusion

The prevalence of MiP and AiP among pregnant women in the Akatsi South District remains a great concern. High utilization of IPTp-SP and LLIN was observed with a resultant positive effect on malaria prevalence among pregnant women. Improved access to IPTp-SP and LLIN is hence encouraged to help further diminish the risk of malaria infection amongst pregnant women in the District.

Low birth weight and its associated risk factors in a rural health district of Burkina Faso: a cross sectional study

Background

Low birth weight (LBW) is a major factor of neonate mortality that particularly affects developing countries. However, the scarcity of data to support decision making to reduce LBW occurrence is a major obstacle in sub-Saharan Africa. The aim of this research was to determine the prevalence and associated factors of LBW at the Yako health district in a rural area of Burkina Faso.

Methods

A cross sectional survey was conducted at four peripheral health centers among mothers and their newly delivered babies. The mothers’ socio-demographic and obstetrical characteristics were collected by face-to-face interview or by review of antenatal care books. Maternal malaria was tested by standard microscopy and neonates’ birth weights were documented. Multivariate logistic regression was used to determine factors associated with LBW. A p-value < 0.05 was considered statistically significant.

Results

Of 600 neonates examined, the prevalence of low birth weight was 11.0%. Adjustment for socio-demographic characteristic, medical conditions, obstetrical history, malaria prevention measures by multivariate logistic regression found that being a primigravid mother (aOR = 1.8, [95% CI: 1.1–3.0]), the presence of malaria infection (aOR = 1.9, [95% CI: 1.1–3.5]), the uptake of less than three doses of sulfadoxine-pyrimethamine for the intermittent preventive treatment of malaria in pregnancy (IPTp-SP) (aOR = 2.2, [95% CI: 1.3–3.9]), the presence of maternal fever at the time of delivery (aOR = 2.8, [95% CI: 1.5–5.3]) and being a female neonate (aOR = 1.9, [95% CI: 1.1–3.3]) were independently associated with an increased risk of LBW occurrence. The number of antenatal visits performed by the mother during her pregnancy did not provide any direct protection for low birth weight.

Conclusion

The prevalence of LBW remained high in the study area. Maternal malaria, fever and low uptake of sulfadoxine-pyrimethamine doses were significantly associated with LBW and should be adequately addressed by public health interventions.

Differentials in prevalence and correlates on uptake of tetanus toxoid and intermittent preventive treatment with sulfadoxine-pyrimethamine during pregnancy: A community-based cross-sectional study in The Gambia

Objectives:

The study examined the differentials in prevalence and correlates on the uptake of tetanus toxoid and intermittent preventive treatment of malaria among pregnant women in The Gambia.

Methods:

The 2018 data from The Gambia Multiple Indicators Cluster Survey were analyzed. Data from 6143 women of reproductive age who have given birth were extracted for the analysis. Percentages and Chi-square tests were used. In addition, a multivariable logistic regression model was used to calculate the adjusted odds ratios (with a corresponding 95% confidence interval). The level of significance was set at p < 0.05.

Results:

The prevalence of tetanus toxoid uptake among women in The Gambia was 88.2%, while that of the adequate tetanus toxoid doses was 34.8%. The prevalence of intermittent preventive treatment with sulfadoxine-pyrimethamine uptake among maternal women in The Gambia was 98.6%, while that of the adequate intermittent preventive treatment with sulfadoxine-pyrimethamine doses taken was 34.3%. The identified statistically significant covariates of tetanus toxoid immunization and intermittent preventive treatment with sulfadoxine-pyrimethamine uptake includes women’s age, local government areas, parity, use of radio, use of newspaper, and antenatal care visits.

Conclusion:

The current utilization rate for adequate intermittent preventive treatment with sulfadoxine-pyrimethamine and tetanus toxoid immunization during pregnancy in The Gambia is very low and even below universal levels. The country needs to strengthen more and effective mass media advocacy programs that would target both rural and urban populace, and motivate maternal women to ensure adequate vaccination against malaria and tetanus.

Uptake challenges of intermittent preventive malaria therapy among pregnant women and their health care providers in the Upper West Region of Ghana: A mixed-methods study

BACKGROUND

Malaria in pregnancy remains a major public health problem in endemic countries, especially in sub-Saharan Africa (SSA). Existing interventions such as intermittent preventive therapy in pregnancy (IPTp) using sulfadoxine-pyrimethamine (SP) are effective against placental malaria. However, low uptake of this intervention is a challenge in SSA. This study assessed factors affecting IPTp-SP uptake among pregnant women as well as their health care providers, including health system-related factors.

METHODS

From November 2018 until May 2019 a mixed-methods study was conducted in one urban and one rural district of the Upper West Region of Ghana. A multi-stage sampling technique was used to recruit 740 3rd trimester pregnant women and 74 health service providers from 37 antenatal care (ANC) facilities. Quantitative data was collected through a standard questionnaire from pregnant women and ANC service providers. Three focus group discussions (FGDs) were conducted in each district with pregnant women who had defaulted on their IPTp doses to collect information about the challenges in accessing IPTp-SP. The primary outcome was the uptake of IPTp-SP during antenatal care visits. In addition, the health care provider and health system-related factors on the administration of SP were assessed, as well as details of folic acid (FA) supplementation. Data were analysed using descriptive statistics and Poisson regression.

RESULTS

Responses from 697 pregnant women were analysed. Of these, 184 (26.4%) had taken the third dose of SP (SP3) in line with international guidelines. IPTp-SP uptake was low and significantly associated with the number of maternal ANC contacts and their gestational age at 1st ANC contact. Most pregnant women were regularly co-administered SP together with 5 mg of FA, in contrast to the international recommendations of 0.4 mg FA. The main challenges to IPTp-SP uptake were missed ANC contacts, knowledge deficiencies among pregnant women of the importance of IPTp, and frequent drug stock outs, which was confirmed both from the ANC providers as well as from the pregnant women. Further challenges reported were provider negligence/absenteeism, adverse drug reactions, and mobile residency of pregnant women.

CONCLUSIONS

The uptake of IPTp-SP in the study area is still very low, which is partly explained by frequent drug stock outs at health facilities, staff absenteeism, knowledge deficiencies among pregnant women, and missed ANC contacts. The high dosing of co-administered FA is against international recommendations. These observations need to be addressed by the national public health authorities.

Magnitude of low birthweight in malaria endemic settings of Nanoro, rural Burkina Faso: a secondary data analysis

Low birthweight (LBW) is a worldwide problem that particularly affects developing countries. However, limited information is available on its magnitude in rural area of Burkina Faso. This study aimed to estimate the prevalence of low birthweight and to identify its associated factors in Nanoro health district. A secondary analysis of data collected during a cross-sectional survey was conducted to assess the prevalence of low birthweight in Nanoro health and demographic surveillance system area (HDSS). Maternal characteristics extracted from antenatal care books or by interview, completed by malaria diagnosis were examined through a multi-level logistic regression to estimate odd-ratios of association with low birthweight. Significance level was set at 5%. Of the 291 neonates examined, the prevalence of low birthweight was 12%. After adjustment for socio-demographic, obstetric and malaria prevention variables, being primigravid (OR = 8.84, [95% CI: 3.72-21.01]), or multigravid with history of stillbirth (OR = 5.03, [95% CI: 1.54-16.40]), as well as the lack of long-lasting insecticide treated bed net use by the mother the night preceding the admission for delivery (OR = 2.5, [95% CI: 1.1-5.9]) were significantly associated with neonate low birthweight. The number of antenatal visits however did not confer any direct benefit on birthweight status within this study area. The prevalence of low birthweight was high in the study area and represents an important public health problem in Burkina Faso. In light of these results, a redefinition of the content of the antenatal care package is needed.

Is improvement in indicators of women's empowerment associated with uptake of WHO recommended IPTp-SP levels in sub-Saharan Africa? A multilevel approach

OBJECTIVES

The global burden of malaria has reduced considerably; however, malaria in pregnancy remains a major public health problem in sub-Saharan Africa (SSA), where about 32 million pregnant women are at risk of acquiring malaria. The WHO has recommended that pregnant women in high malaria transmission locations, including SSA, have intermittent preventive treatment of malaria during pregnancy with at least three doses of sulphadoxine-pyrimethamine (IPTp-SP). Therefore, we investigated the prevalence of IPTp-SP uptake and associated individual-level, community-level and country-level predictors in SSA.

DESIGN

A cross-sectional survey was conducted using recent Demographic and Health Surveys datasets of 20 SSA countries. A total of 96 765 women were included. Optimum uptake of IPTp-SP at most recent pregnancy was the outcome variable. We fitted three-level multilevel models: individual, community and country parameters at 95% credible interval.

RESULTS

In all, 29.2% of the women had optimal IPTp-SP uptake ranging from 55.1% (in Zambia) to 6.9% (in Gambia). The study revealed a high likelihood of optimum IPTp-SP uptake among women with high knowledge (aOR=1.298, Crl 1.206 to 1.398) relative to women with low knowledge. Women in upper-middle-income countries were more than three times likely to have at least three IPTp-SP doses compared with those in low-income countries (aOR=3.268, Crl 2.392 to 4.098). We found that community (σ²=1.999, Crl 1.088 to 2.231) and country (σ²=1.853, Crl 1.213 to 2.831) level variations exist in optimal uptake of IPTp-SP. According to the intracluster correlation, 53.9% and 25.9% of the variation in optimum IPTp-SP uptake are correspondingly attributable to community-level and country-level factors.

CONCLUSIONS

The outcome of our study suggests that low-income SSA countries should increase budgetary allocation to maternal health, particularly for IPTp-SP interventions. IPTp-SP advocacy behavioural change communication strategies must focus on women with low knowledge, rural dwellers, married women and those who do not meet the minimum of eight antenatal care visits.

Factors influencing the uptake of intermittent preventive treatment among pregnant women in sub-Saharan Africa: a multilevel analysis

Background

Intermittent Preventive Treatment (IPT) of malaria in pregnancy is a full therapeutic course of antimalarial sulfadoxine-pyrimethamine (SP) medicine given to pregnant women in their second trimester at routine antenatal care visits, regardless of whether the recipient is infected with malaria. Given the negative consequences of malaria in pregnancy, studies on Intermittent Preventive Therapy with Sulfadoxine-Pyrimethamine (IPTp-SP) are important benchmarks for understanding the extent of malaria control and prevention during pregnancy. We, therefore, examined the factors associated with the uptake of IPTp-SP among pregnant women in sub-Saharan Africa.

Methods

We used data from the current versions of the Malaria Indicators Survey of 12 countries in sub-Saharan Africa. Women aged 15–49 years participated in the surveys. The analyses were carried out using Stata version 14.2. Descriptive (frequencies and percentages) and multilevel regression analyses were carried out. The results of the multilevel regression analysis were presented as adjusted odds ratios (aOR) with 95% confidence intervals (CIs). 

Results

The average prevalence of uptake of IPTp-SP among pregnant women in the studied sub-Saharan African countries was 30.69%, with the highest and lowest prevalences in Ghana (59.64%) and Madagascar (10.08%), respectively. Women aged 40–44 compared to those aged 15–19 (aOR = 1.147, 95%CI = [1.02,1.30) had higher odds of receiving 3 or more doses of IPTp-SP. Women with a secondary/higher level of education compared to those with no formal education (aOR = 1.12, 95%CI = 1.04,1.20] also had higher odds of receiving 3 or more doses of IPTp-SP. Women who were exposed to malaria messages on the radio (aOR = 1.07, 95%CI = 1.02,1.12] and television (aOR = 1.13,95%CI = [1.05,1.21]) had higher odds of receiving 3 or more doses of IPTp-SP compared to those who were not exposed.

Conclusion

Our study indicates that the uptake of IPTp-SP is relatively low among the countries included in this study, with significant inter-country variations. Higher educational level, exposure to media, low parity, and higher age group were associated with higher odds of optimal IPTp-SP uptake. National policies, programs, guidance services such as information service and counselling and other interventions aimed at improving the coverage and uptake of IPTp-SP must be targeted at women with low level of education, non-exposure to media, high parity, and younger age group to attain the desired outcome.

Risk factors for Plasmodium falciparum infection in pregnant women in Burkina Faso: a community-based cross-sectional survey

Background

Malaria in pregnancy remains a public health problem in sub-Saharan Africa. Identifying risk factors for malaria in pregnancy could assist in developing interventions to reduce the risk of malaria in Burkina Faso and other countries in the region.

Methods

Two cross-sectional surveys were carried out to measure Plasmodium falciparum infection using microscopy in pregnant women in Saponé Health District, central Burkina Faso. Data were collected on individual, household and environmental variables and their association with P. falciparum infection assessed using multivariable analysis.

Results

A total of 356 pregnant women were enrolled in the surveys, 174 during the dry season and 182 during the wet season. The mean number of doses of sulfadoxine–pyrimethamine for Intermittent Preventive Treatment in pregnancy (IPTp-SP) was 0.4 doses during the first trimester, 1.1 doses at the second and 2.3 doses at the third. Overall prevalence of P. falciparum infection by microscopy was 15.7%; 17.8% in the dry season and 13.7% in the wet season. 88.2% of pregnant women reported sleeping under an insecticide-treated net (ITN) on the previous night. The odds of P. falciparum infection was 65% lower in women who reported using an ITN compared to those that did not use an ITN (Odds ratio, OR = 0.35, 95% CI 0.14–0.86, p = 0.02). IPTp-SP was also associated with reduced P. falciparum infection, with each additional dose of IPTp-SP reducing the odds of infection by 44% (OR = 0.56, 95% CI 0.39–0.79, p = 0.001). Literate women had a 2.54 times higher odds of P. falciparum infection compared to illiterate women (95% CI 1.31–4.91, p = 0.006).

Conclusions

The prevalence of P. falciparum infection among pregnant women remains high in Burkina Faso, although use of IPTp-SP and ITNs were found to reduce the odds of infection. Despite this, compliance with IPTp-SP remains far from that recommended by the National Malaria Control Programme and World Health Organization. Behaviour change communication should be strengthened to encourage compliance with protective malaria control tools during pregnancy.

Determinants of the uptake of intermittent preventive treatment of malaria in pregnancy with sulphadoxine pyrimethamine in Sabatia Sub County, Western Kenya

BACKGROUND

Annually, 125.2 million pregnant women worldwide risk contracting malaria, including 30.3 million and 1.5 million in Sub-Saharan Africa and Kenya respectively. At least three doses of sulphadoxine pyrimethamine for intermittent preventive treatment of malaria in pregnancy (IPTp-SP) is recommended for optimal benefit. Kenya recorded low IPTp-SP optimal uptake in 2015. This study investigated the prevalence of and factors influencing IPTp-SP optimal uptake in Sabatia Sub County, Western Kenya.

METHODS

A cross-sectional study was conducted in Sabatia Sub County from April to October 2020. Using a validated semi-structured questionnaire, data were obtained from 372 randomly sampled post-delivery women aged 15-49 years with live birth within one year preceding the study. Women on cotrimoxazole prophylaxis during pregnancy were excluded. Pearson Chi-square and Fisher's Exact test were measures of association used. Binary logistic regression analysed predictors of optimal IPTp-SP uptake.

RESULTS

Optimal IPTp-SP uptake was 79.6%, 95% CI 75.5%-83.7%. Predictors of IPTp-SP optimization were gestational age at first antenatal care (ANC) visit (P = 0.04), frequency of ANC visits (P < 0.001), maternal knowledge of IPTp-SP benefits (P < 0.001), maternal knowledge of optimal sulphadoxine pyrimethamine (SP) dose (P = 0.03) and SP administration at ANC clinic (P = 0.03). Late ANC initiators were less likely to receive optimal IPTp-SP (aOR = 0.4, 95% CI 0.2-0.9). Odds of optimizing IPTp-SP increased among women with ≥ 4 ANC visits (aOR = 16.7, 95% CI 7.9-35.3), good knowledge of IPTp-SP benefits (aOR = 2.4, 95% CI 1.3-4.5) and good knowledge of optimal SP dose (aOR = 1.9, 95% CI 1.1-3.4). Women who never missed being administered SP were highly likely to receive optimal IPTp-SP (aOR = 2.9, 95% CI 1.1-7.2) CONCLUSIONS: This study has found high IPTp-SP optimal uptake in the study area. Efforts should be directed towards early and more frequent ANC visits. Intensive and targeted health education is required. It's fundamental to adequately stock and consistently administer SP. Future studies considering larger samples and health workers' perspectives of the health system delivery factors are recommended.

Coverage of intermittent preventive treatment of malaria in pregnancy in four sub-Saharan countries: findings from household surveys

Background

Intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is a key malaria prevention strategy in areas with moderate to high transmission. As part of the TIPTOP (Transforming IPT for Optimal Pregnancy) project, baseline information about IPTp coverage was collected in eight districts from four sub-Saharan countries: Democratic Republic of Congo (DRC), Madagascar, Mozambique and Nigeria.

Methods

Cross-sectional household surveys were conducted using a multistage cluster sampling design to estimate the coverage of IPTp and antenatal care attendance. Eligible participants were women of reproductive age who had ended a pregnancy in the 12 months preceding the interview and who had resided in the selected household during at least the past 4 months of pregnancy. Coverage was calculated using percentages and 95% confidence intervals.

Results

A total of 3911 women were interviewed from March to October 2018. Coverage of at least three doses of IPTp (IPTp3+) was 22% and 24% in DRC project districts; 23% and 12% in Madagascar districts; 11% and 16% in Nigeria local government areas; and 63% and 34% in Mozambique districts. In DRC, Madagascar and Nigeria, more than two-thirds of women attending at least four antenatal care visits during pregnancy received less than three doses of IPTp.

Conclusions

The IPTp3+ uptake in the survey districts was far from the universal coverage. However, one of the study districts in Mozambique showed a much higher coverage of IPTp3+ than the other areas, which was also higher than the 2018 average national coverage of 41%. The reasons for the high IPTp3+ coverage in this Mozambican district are unclear and require further study.

Decomposition of socioeconomic inequalities in the uptake of intermittent preventive treatment of malaria in pregnancy in Nigeria: evidence from Demographic Health Survey

Background

Although malaria in pregnancy is preventable with the use of intermittent preventive treatment with sulfadoxine–pyrimethamine (IPTp-SP), it still causes maternal morbidity and mortality, in sub-Saharan Africa and Nigeria in particular. Socioeconomic inequality leads to limited uptake of IPTp-SP by pregnant women and is, therefore, a public health challenge in Nigeria. This study aimed to measure and identify factors explaining socioeconomic inequality in the uptake of IPTp-SP in Nigeria.

Methods

The study re-analysed dataset of 12,294 women aged 15–49 years from 2018 Nigeria Demographic Health Survey (DHS). The normalized concentration index (C_n) and concentration curve were used to quantify and graphically present socioeconomic inequalities in the uptake of IPTp-SP among pregnant women in Nigeria. The C_n was decomposed to identify key factors contributing to the observed socioeconomic inequality in the uptake of adequate (≥ 3) IPTp-SP.

Results

The study showed a higher concentration of the adequate uptake of IPTp-SP among socioeconomically advantaged women (C_n = 0.062; 95% confidence interval [CI] 0.048 to 0.076) in Nigeria. There is a pro-rich inequality in the uptake of IPTp-SP in urban areas (C_n = 0.283; 95%CI 0.279 to 0.288). In contrast, a pro-poor inequality in the uptake of IPTp-SP was observed in rural areas (C_n = − 0.238; 95%CI − 0.242 to − 0.235). The result of the decomposition analysis indicated that geographic zone of residence and antenatal visits were the two main drivers for the concentration of the uptake of IPTp-SP among wealthier pregnant women in Nigeria.

Conclusion

The pro-rich inequalities in the uptake of IPTp-SP among pregnant women in Nigeria, particularly in urban areas, warrant further attention. Strategies to improve the uptake of IPTp-SP among women residing in socioeconomically disadvantaged geographic zones (North-East and North-West) and improving antenatal visits among the poor women may reduce pro-rich inequality in the uptake of IPTp-SP among pregnant women in Nigeria.

Determinants of intermittent preventive treatment with sulfadoxine-pyrimethamine in pregnant women (IPTp-SP) in Mali, a household survey

Background

In malaria endemic regions, intermittent preventive treatment with sulfadoxine-pyrimethamine (IPTp-SP) is recommended for all pregnant women during prenatal consultation, from the fourth month of pregnancy up to the time of delivery. The Government of Mali is aiming for universal coverage of IPTp-SP. However, coverage is still low, estimated to be 18% for completion of three doses (IPTp-SP3). The objective of this study was to identify the factors that influence IPTp-SP adherence in the Health District of Sélingué, Mali.

Methods

This was a cross-sectional survey with 30 clusters, proportional to village size, with two stages of sampling. Data were collected electronically with Magpi software during face-to-face interviews/surveys. The data were analysed with SPSS version 20. A descriptive analysis and bivariate and multivariate logistic regression were performed. An equity analysis examined the effect of distance from health care facility on completion of three or more antenatal visits (ANC3 +) and three or more doses of intermittent preventive treatment (IPTp-SP3 +).

Results

Of the 1,021 women surveyed, 87.8% (n = 896) attended at least one ANC visit. Of these, 86.3% (n = 773) received at least one dose of IPTp-SP. Compliance with three or more doses of IPTp-SP was 63.7%. The determinants statistically related to ANC3 + were the early initiation of ANC (OR = 3.22 [1.22, 10.78]), and the presence of a community health centre (CHC) in the village (OR = 9.69 [1.09, 86.21]). The ability to read (OR = 1.60 [1.01, 2.55]), the early initiation of ANC (OR = 1.46 [1.06, 2.00], knowledge of the utility of the drug (OR = 2.38 [1.24, 4.57]), and knowledge of the recommended dose of the drug (OR = 6.11 [3.98, 9.39]) were related to completion of three or more treatments (IPTp-SP3 +).

Conclusion

The early initiation of ANC was a positive determinant of the completeness of both ANC3 + and IPTp-SP3 + . This study shows that a successful implementation of the IPTp strategy can be achieved by improving access to prenatal care at community health facilities, and strengthening patient-provider communication to ensure adequate knowledge on dosing of IPTp-SP and the benefits to mother and child.

Late ANC initiation and factors associated with sub-optimal uptake of sulphadoxine-pyrimethamine in pregnancy: a preliminary study in Cape Coast Metropolis, Ghana

Background

Malaria infection during pregnancy is of public health importance as it poses risk to the pregnant woman, her foetus and the newborn child. Intermittent preventive treatment during pregnancy using sulphadoxine-pyrimethamine is one way of reducing the effect of the disease on pregnancy outcomes. The study determined factors associated with uptake of sulphadoxine-pyrimethamine during pregnancy in the Cape Coast Metropolis of Ghana.

Methods

A health facility-based cross-sectional study involving pregnant women of ≥36 weeks gestation visiting antenatal clinics in three selected health facilities in the Cape Coast Metropolis was conducted. Participants were consecutively recruited using a structured questionnaire over a 6-week period from May to June, 2018. Descriptive statistics was used to summarize the data whilst Pearson’s chi-square/Fisher exact test was performed to determine associations and logistic regression done to determine the strength of the associations.

Results

A total of 212 pregnant women participated in the study. Formal education, initiating ANC early, taking first dose of SP during second trimester, not experiencing side effects of SP, having knowledge about schedule for taking SP and making ≥4 ANC visits were factors associated with uptake of ≥3 doses of IPTp-SP. Logistic regression analysis revealed that, mothers who made ≥4 ANC visits were 53.77 times more likely to take ≥3 doses of SP compared with those who made < 4 ANC visits (p <  0.001). Those who initiated ANC during the first trimester were 3.60 times more likely to receive ≥5 doses compared with those who initiated ANC during the second or third trimester (p = 0.022). Making ≥8 ANC visits did not increase the chances of taking ≥5 doses of SP.

Conclusion

Health promotion programmes targeting mothers with no formal education could increase their awareness about the importance of ANC services including uptake of IPTp-SP.

Spatial distribution and sociodemographic risk factors of malaria in Nigerian children less than 5 years old

Malaria remains a leading cause of morbidity and mortality among children in Nigeria less than 5 years old (under-5). This study utilized nationally representative secondary data extracted from the 2015 Nigeria Malaria Indicator Survey (NMIS) to investigate the spatial variability in malaria distribution in those under- 5 and to explore the influence of socioeconomic and demographic factors on malaria prevalence in this population group. To account for spatial correlation, a Spatially Generalized Linear Mixed Model (SGMM) was employed and predictive risk maps was developed using Kriging. Highly significant spatial variability in under-5 malaria distribution was observed (P<0.0001) with a higher likelihood of malaria prevalence in this group in the Northwest and North-east of the country. The number of malaria infections increased with age, children aged between 49-59 months were found to be at a higher risk (Odds Ratio=4.680, 95% CI=3.674 to 5.961 at P<0.0001). After accounting for spatial correlation, we observed a strong significant association between the non-availability or non-use of mosquito bed-nets, low household socioeconomic status, low level of mother's educational attainment, family size, anaemia prevalence, rural type of residence and under-5 malaria prevalence. Faced with a high rate of under-5 mortality due to malaria in Nigeria, targeted interventions (which requires the identification of the child's location) may reduce malaria prevalence, and we conclude that socioeconomic impediments need to be confronted to reduce the burden of childhood malaria infection.

Socioeconomic inequality in intermittent preventive treatment using Sulphadoxine pyrimethamine among pregnant women in Nigeria

BACKGROUND

Intermittent preventive treatment using Sulphadoxine pyrimethamine (IPTp-SP) for malaria prevention is recommended for all pregnant women in malaria endemic areas. However, there is limited evidence on the level of socioeconomic inequality in IPTp-SP use among pregnant women in Nigeria. Thus, this study aimed to determine the level of socioeconomic inequality in IPTp-SP use among pregnant women in Nigeria and to decompose it into its contributing factors.

METHODS

A secondary data analysis of Nigerian demographic and health survey of 2018 was conducted. A sample of 21,621 pregnant women aged between 15 and 49 years and had live birth in the previous 2 years before the survey were included in this analysis. The study participants were recruited based on a stratified two-stage cluster sampling method. Socioeconomic inequality was decomposed into its contributing factors by concentration index.

RESULT

Totally 63.6% of pregnant women took at least one dose of IPTp-SP prophylaxis. Among IPTp-SP users, 35.1% took one dose, 38.6% took two doses and 26.2% took three doses and more. Based on both concentration index of 0.180 (p-value = < 0.001, 95% CI: 0.176 to 0.183) and Erreyger's normalization concentration index 0.280 (p-value = < 0.001, 95% CI: 0.251 to 0.309), the IPTp-SP utilization was pro-rich. The largest contributors to the inequality in IPTp-SP uptake were wealth index (47.81%) and educational status (28.66%).

CONCLUSION

Our findings showed that IPTp-SP use was pro-rich in Nigeria. Wealth index and educational status were the factors that significantly contributed to the inequality. The disparities could be reduced through free IPTp service expansion by targeting pregnant women from low socioeconomic status.

Prevalence of placental malaria among asymptomatic pregnant women in Wolkite health center, Gurage zone, Southern Ethiopia

BACKGROUND

Placental malaria (PM) is a major public health problem associated with adverse pregnancy outcomes such as low birth weight (LBW), preterm delivery and maternal anemia. The present study is aimed to determine the prevalence of placental malaria among asymptomatic pregnant women in Wolkite health center, Gurage zone, Southern Ethiopia.

METHOD

Facility-based cross-sectional study was carried out from June 2019 to August 2019. A total of 230 pregnant women were involved in the study where socio-demographic data, medical and obstetric history were collected using pretested structured questionnaires. Blood samples were collected at delivery from maternal capillary, placenta and umbilical cord for the detection of malarial parasite. Maternal hematocrit was determined to screen for anemia.

RESULT

In this study, the prevalence of placental malaria, peripheral malaria and umbilical cord malaria was 3.9% (9/230), 15.2% (35/230) and 2.6% (6/230) respectively. Plasmodium falciparum and Plasmodium vivax were detected by microscopy. All babies with positive umbilical cord blood films were born from a mother with placental malaria. Maternal anemia was recorded in 58.3% of the women. In univariate analysis, placental malaria was significantly associated with LBW (p < 0.001) unlike parity and maternal anemia.

CONCLUSION

Placental malaria among asymptomatic pregnant women is low in Wolkite health centre, Gurage zone in Southern Ethiopia. Moreover, placental malaria was strongly associated with LBW. Thus, further strengthening the existing prevention and control activities and screening of asymptomatic pregnant women as part of routine antenatal care service is very essential.

Impact of Health Systems on the Implementation of Intermittent Preventive Treatment for Malaria in Pregnancy in Sub-Saharan Africa: A Narrative Synthesis

Malaria in pregnancy is a public health challenge with serious negative maternal and newborn consequences. Intermittent preventive treatment (IPTp) with sulphadoxine-pyrimethamine is recommended for the control of malaria during pregnancy within endemic areas, but coverage for the recommended ≥3 doses IPTp regimen has remained suboptimal. We searched PubMed, Cochrane library, and HINARI database from 1 January 2010 to 23 May 2020, for studies investigating the effect of the health system on IPTp implementation. Data extraction was independently performed by two investigators and evaluated for quality and content. Health system barriers and facilitators were explored using thematic analysis and narrative synthesis. Thirty-four out of 1032 screened articles were included. Key health system issues affecting the provision and uptake of IPTp were the ambiguity of policy and guidelines for IPTp administration, human resource shortages, drug stock-outs, conflicting policy implementation on free IPTp provision, hidden costs, unclear data recording and reporting guidelines, and poor quality of care. Factors affecting the supply and demand for IPTp services involve all pillars of the health system across different countries. The success of health programs such as IPTp will thus depend on how well the different pillars of the health system are articulated towards the success of each program.

Coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) influences delivery outcomes among women with obstetric referrals at the district level in Ghana

Background

The aim of the study was to determine the coverage of intermittent preventive treatment of malaria in pregnancy (IPTp) and its relationship with delivery outcomes among obstetric referral cases at the district level of healthcare.

Methods

An implementation research within three districts of the Greater Accra region was conducted from May 2017 to February 2018, to assess the role of an enhanced inter-facility communication system on processes and outcomes of obstetric referrals. A cross-sectional analysis of the data on IPTp coverage as well as delivery outcomes for the period of study was conducted, for all the referrals ending up in deliveries. Primary outcomes were maternal and neonatal complications at delivery. IPTp coverage was determined as percentages and classified as adequate or inadequate. Associated factors were determined using Chi square. Odds ratios (OR, 95% CI) were estimated for predictors of adequate IPTp dose coverage for associations with delivery outcomes, with statistical significance set at p = 0.05.

Results

From a total of 460 obstetric referrals from 16 lower level facilities who delivered at the three district hospitals, only 223 (48.5%) received adequate (at least 3) doses of IPTp. The district, type of facility where ANC is attended, insurance status, marital status and number of antenatal clinic visits significantly affected IPTp doses received. Adjusted ORs show that adequate IPTp coverage was significantly associated with new-born complication [0.80 (0.65–0.98); p = 0.03], low birth weight [0.51 (0.38–0.68); p < 0.01], preterm delivery [0.71 (0.55–0.90); p = 0.01] and malaria as indication for referral [0.70 (0.56–0.87); p < 0.01]. Positive association with maternal complication at delivery was seen but was not significant.

Conclusion

IPTp coverage remains low in the study setting and is affected by type of health facility that ANC is received at, access to health insurance and number of times a woman attends ANC during pregnancy. This study also confirmed earlier findings that, as an intervention IPTp prevents bad outcomes of pregnancy, even among women with obstetric referrals. It is important to facilitate IPTp service delivery to pregnant women across the country, improve coverage of required doses and maximize the benefits to both mothers and newborns.

Prevalence of pfdhfr and pfdhps mutations in Plasmodium falciparum associated with drug resistance among pregnant women receiving IPTp-SP at Msambweni County Referral Hospital, Kwale County, Kenya

BACKGROUND

Prevention and treatment of malaria during pregnancy is crucial in dealing with maternal mortality and adverse fetal outcomes. The World Health Organization recommendation to treat all pregnant women with sulfadoxine-pyrimethamine (SP) through antenatal care structures was implemented in Kenya in the year 1998, but concerns about its effectiveness in preventing malaria in pregnancy has arisen due to the spread of SP resistant parasites. This study aimed to determine the prevalence of SP resistance markers in Plasmodium falciparum parasites isolated from pregnant women seeking antenatal care at Msambweni County Referral Hospital, located in coastal Kenya, between the year 2013 and 2015.

METHODS

This hospital-based study included 106 malaria positive whole blood samples for analysis of SP resistance markers within the Pfdhfr gene (codons 51, 59 and 108) and Pfdhps gene (codons 437 and 540). The venous blood collected from all pregnant women was tested for malaria via light microscopy, then the malaria positive samples were separated into plasma and red cells and stored in a - 86° freezer for further studies. Archived red blood cells were processed for molecular characterization of SP resistance markers within the Pfdhfr and Pfdhps genes using real time PCR platform and Sanger sequencing.

RESULTS

All samples had at least one mutation in the genes associated with drug resistance; polymorphism prevalence of Pfdhfr51I, 59R and 108N was at 88.7%, 78.3% and 93.4%, respectively, while Pfdhps polymorphism accounted for 94.3% and 91.5% at 437G and 540E, respectively. Quintuple mutations (at all the five codons) conferring total SP resistance had the highest prevalence of 85.8%. Quadruple mutations were observed at a frequency of 10.4%, and 24.5% had a mixed outcome of both wildtype and mutant genotypes in the genes of interest.

CONCLUSION

The data suggest a high prevalence of P. falciparum genetic variations conferring resistance to SP among pregnant women, which may explain reduced efficacy of IPTp treatment in Kenya. There is need for extensive SP resistance profiling in Kenya to inform IPTp drug choices for successful malaria prevention during pregnancy.

Correlates of uptake of optimal doses of sulfadoxine-pyrimethamine for prevention of malaria during pregnancy in East-Central Uganda

Background

In 2012, the World Health Organization recommended that pregnant women in malaria-endemic countries complete at least three (optimal) doses of intermittent preventive treatment (IPTp) using sulfadoxine-pyrimethamine (SP) to prevent malaria and related adverse events during pregnancy. Uganda adopted this recommendation, but uptake remains low in East-Central and information to explain this low uptake remains scanty. This analysis determined correlates of uptake of optimal doses of IPTp-SP in East-Central Uganda.

Methods

This was a secondary analysis of the 2016 Uganda Demographic Health Survey data on 579 women (15–49 years) who attended at least one antenatal care (ANC) visit and had a live birth within 2 years preceding the survey. Uptake of IPTp-SP was defined as optimal if a woman received at least three doses; partial if they received 1–2 doses or none if they received no dose. Multivariate analysis using multinomial logistic regression was used to determine correlates of IPTp-SP uptake.

Results

Overall, 22.3% of women received optimal doses of IPTp-SP, 48.2% partial and 29.5% none. Attending ANC at a lower-level health centre relative to a hospital was associated with reduced likelihood of receiving optimal doses of IPTp-SP. Belonging to other religious faiths relative to Catholic, belonging to a household in the middle relative to poorest wealth index, and age 30 and above years relative to 25–29 years were associated with higher likelihood of receiving optimal doses of IPTp-SP.

Conclusions

In East-Central Uganda, uptake of optimal doses of IPTp-SP is very low. Improving institutional delivery and household wealth, involving religious leaders in programmes to improve uptake of IPTp-SP, and strengthening IPTp-SP activities at lower level health centers may improve uptake of IPTp-SP in the East-Central Uganda.

Coverage and effectiveness of intermittent preventive treatment in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) on adverse pregnancy outcomes in the Mount Cameroon area, South West Cameroon

Background

Growing concerns about the waning efficacy of IPTp-SP warrants continuous monitoring and evaluation. This study determined coverage of IPTp-SP and compared the effectiveness of the 3-dose to 2-dose regimen on placental malaria (PM) infection and low birth weight (LBW) in the Mount Cameroon area.

Methods

Consenting pregnant women were enrolled consecutively through a cross-sectional survey at delivery at four antenatal clinics, two each from semi-rural and semi-urban settings from November 2016 to December 2017. Reported IPTp-SP use, demographic and antenatal clinic (ANC) data of the mothers and neonate birth weights were documented. Maternal haemoglobin concentration was measured using a haemoglobinometer and PM infection diagnosed by placental blood microscopy. Logistic regression analysis was used to model study outcomes.

Results

Among the 465 parturient women enrolled, 47.0% (203), 34.7% (150), 18.3% (79) and 7.1% (33) reported uptake of ≥ 3, 2.1 dose(s) and no SP, respectively. Uptake of ≥ 3 doses varied significantly (p < 0.001) according to type of medical facility, timing of ANC initiation and number of ANC visits. The prevalence of PM was 18.5% where uptake of ≥ 3 SP doses (AOR = 2.36: 95% CI  1.41–4.87), primiparity (AOR = 2.13: 95% CI  1.19–3.81), semi-rural setting (AOR = 1.85: 95% CI  1.12–3.04) increased odds of infection. Also, three or more dosing was associated (p < 0.001) with increased PM density notably among women from semi-urban areas. Compared with third trimester, ANC initiation in the second trimester (AOR: 0.39: 95% CI  0.20–0.74) lower odds of infection. The prevalence of LBW infants was 7.3% and were generally those of anaemic (AOR: 4.6: 95% CI  1.03–20.57) and semi-rural (AOR: 5.29: 95% CI  1.73–16.15) women. Although ≥ 3 (AOR: 0.31: 95% CI  0.11–0.87) and 2 (AOR: 0.32: 95% CI  0.11–0.93) doses of SP was associated with lower odds of LBW, ≥ 3 doses were not associated with additional increase in birth weight nor maternal haemoglobin levels when compared with 2 doses.

Conclusion

In the Mount Cameroon area, reported uptake of IPTp with ≥ 3 SP doses did not provide observable prophylactic benefits. SP resistance efficacy studies are necessary.

Uptake of intermittent preventive treatment for malaria in pregnancy among women in selected communities of Ebonyi State, Nigeria

Background

Malaria in pregnancy has adverse effects on maternal and child health. Intermittent preventive treatment (IPTp) with three doses of Sulfadoxine/Pyrimethamine is an effective preventive measure for malaria in pregnancy. However, 24.0% of women use this prophylactic regimen in Ebonyi State. Previous studies have focused on the level of uptake with less attention given to factors influencing uptake. Therefore, we examined the predictors of IPTp uptake in the last pregnancy among women in Ebonyi State, Nigeria.

Methods

This was a community-based cross-sectional study among 340 women of reproductive age selected using multistage sampling technique. A semi-structured interviewer administered questionnaire was used to collect data on socio-demographic characteristics of respondents, IPTp uptake and reasons for not taking IPTp. Adherence was judged adequate if three or more doses of IPTp were taken, otherwise inadequate. Data were analyzed using descriptive statistics, Chi- square test and logistic regression model at 5% level of significance.

Results

Mean age of respondents was 28.8 ± 5.2 years, 96.5% were married, 19.4% had tertiary education, and 11.2% were from polygamous family. Uptake of IPTp was 74.2%. The level of IPTp uptake was 12.5 and 41.0% among women with no formal and tertiary education respectively. A similar pattern of IPTp uptake was observed among women from monogamous (38.0%) and polygamous (39.5%) families. Women education, husband education and family type were associated with uptake of IPTp, however only husband education remained a predictor of uptake. Women whose husband had secondary education (aOR = 4.1, 95%CI: 1.66–10.06) and tertiary education (aOR = 4.8, 95%CI: 1.76–12.90) were more likely to have IPTp uptake than those whose husbands had below secondary education.

Conclusion

Adequate IPTp uptake among women in their last pregnancy was below WHO recommendation. Intervention aimed at improving couple’s education could facilitate increase in IPTp uptake in Ebonyi State.

Antenatal visits are positively associated with uptake of tetanus toxoid and intermittent preventive treatment in pregnancy in Ivory Coast

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.

Regional variation and demographic factors associated with knowledge of malaria risk and prevention strategies among pregnant women in Nigeria

Pregnant women and children are the most vulnerable populations for malaria infection. Yet, knowledge of risk, and preventive measures are poor among this population. Using the 2015 Nigeria Malaria Indicator Survey, we applied logit link function to estimate the associations of wealth status, educational attainment, and region of residence with malaria risk knowledge and prevention strategies (using a treated mosquito net and malaria drugs) among 739 Nigerian pregnant women aged 15-49 years. Urban women who had obtained a secondary school education (Adjusted odds ratio [aOR] = 2.12; 95% confidence interval [CI] 1.09-4) or higher (aOR = 8.31; 95% CI 3.2-22) had more knowledge of malaria risk. Urban women in the South-West (aOR = 5.02; [CI] 2.02-12.50) and South-East (aOR = 2.68; 95% CI 1.19-6.06) were more likely to use treated mosquito nets during pregnancy. Women in the urban South-West (aOR = 4.04; 95% CI 1.5-11) were more likely to use malaria drugs during pregnancy than those in the North-Central. A wide regional disparity in the knowledge of malaria risks and use of preventive measures exists. Thus, promoting equal access to malaria preventive measures as well as improving knowledge about malaria transmission by mosquitoes should be considered as essential components of ongoing malaria control and elimination efforts in Nigeria.

Assessment of the impact of availability and readiness of malaria services on uptake of intermittent preventive treatment in pregnancy (IPTp) provided during ANC visits in Tanzania

BACKGROUND

Intermittent preventive treatment during pregnancy (IPTp) is a highly-recommended intervention to prevent maternal and neonatal complications associated with malaria infection. Despite fairly high antenatal care (ANC) coverage in Tanzania, low IPTp uptake rates represent a gap in efforts to decrease complications attributed to malaria in pregnancy. The objective of this study was to examine if availability, readiness and managing authority are associated with uptake of IPTp during ANC.

METHODS

Data for this analysis come from a cross-sectional survey, the Tanzania Service Provision Assessment conducted between 2014 and 2015. Principal component analysis was used to create scores for availability of malaria services and readiness for the provision of services. Generalized estimating equation models with logit link and the binomial distribution assessed factors that impact the uptake of IPTp by pregnant women attending ANC.

RESULTS

Higher fraction of women in their third trimester than second (68% versus 49%, OR = 2.6; 95% CI (2.1-3.3)), had received at least one dose of IPTp. There was a wide variation in the availability and readiness of malaria services provision and diagnostic tools by managing authorities. Public facilities were more likely than private to offer malaria rapid diagnostic test, and more providers at public facilities than private diagnosed and/or treated malaria. Women who attended facilities where direct observation therapy was practiced were more likely to have received at least one dose of IPTp (64% versus 46% who received none; p < 0.001). Women who attended ANC at a facility with a high readiness score were more likely to take IPTp than those attending facilities with low readiness scores (OR = 2.1; 95% CI (1.4-3.3)). Reported stock out on the day of interview was negatively associated with IPTp uptake (OR 0.09; 95% CI 0.07-0.1).

CONCLUSION

Readiness of health facilities to provide malaria related services, the number of ANC visits and gestational age were associated with uptake of IPTp among women attending ANC. There are disparities in malaria service availability and readiness across geographical location and managing authorities. These findings could be used to assist the malaria programme and policymakers to appropriately decide when planning for malaria service deliveries and interventions.

Prevalence and Associated Factors of Taking Intermittent Preventive Treatment in Pregnancy in Sierra Leone

Malaria infection during pregnancy is a major public health problem in sub-Saharan Africa. The World Health Organization (WHO) recommends that gestational and congenital malaria can be prevented by using intermittent preventive treatment of malaria in pregnancy with sulfadoxine-pyrimethamine (IPTp-SP). IPTp-SP is a full therapeutic course of antimalarial medicine administered during pregnancy as a component of antenatal care. This study's objective was to assess the prevalence and predictors of IPTp-SP uptake in pregnancy in Sierra Leone. This study was based on the fifth round of the Multiple Indicator Cluster Survey (MICS 5) conducted in Sierra Leone in 2016. Participants were 8526 women aged between 15⁻49 years. Outcome variables were uptake of IPTp-SP during the last pregnancy. Data were analysed using cross-tabulation and logistic regression methods. Results showed that the prevalence of taking IPTp-SP was 94.81% (92.40, 96.14), and that the prevalence of taking at least three doses was 93.24% (92.50, 94.81). In the multivariate logistic regression, education, parity, and antenatal care (ANC) use were significant predictors of IPTp-SP uptake. Women with higher education had lower odds of taking IPTp-SP (Odds Ratio = 0.647, 95%CI = 0.444, 0.943); having higher parity (>4) was associated with lower odds of taking IPTp-SP (OR = 0.663; 95%CI = 0.442, 0.994) and adequate ANC use increased the odds of taking IPTp-SP in both urban (OR = 1.450, 95%CI = 1.158, 3.128) and rural areas (OR = 1.903, 95%CI = 1.069, 1.966). In contrast, the positive association between ANC visits and adequate doses of taking IPTp-SP was true for rural women only (OR = 1.408, 95%CI = 1.174, 1.689). In conclusion, the use of IPTp-SP is close to being universal, with the prevalence being relatively higher in the rural areas. Based on our findings, promoting adequate antenatal care visits should be regarded as a key strategy to improve the use of IPTp-SP in Sierra Leone. Further studies could focus on exploring other predictors of IPTp-SP uptake that are not captured by MICS in Sierra Leone.

Malaria in pregnancy: A community-based study on the knowledge, perception, and prevention among Nigerian women

Background:

Malaria accounts for approximately 1 million deaths annually and about 300,000 deaths in Nigeria alone. Pregnant women and their unborn babies are particularly vulnerable to the adverse consequences of malaria. This study assessed the knowledge, perception, and preventive practices for malaria in pregnancy (MiP) among women in Lagos, Nigeria.

Materials and Methods:

A cross-sectional, descriptive study design was adopted. A total of 422 respondents were selected using multistage sampling technique. Data were collected using a structured, interviewer-administered questionnaire in the first quarter of 2016. Analysis was done with Epi Info™ 7 software with level of significance set at P < 0.05.

Results:

All respondents were aware of MiP, and almost all the respondents (96.2%) were aware that malaria is caused by infected mosquito bite. Majority (89.3%) of the respondents registered for antenatal care in their last pregnancy, but 56.6% did so in the second trimester. A little over half (55.5%) had good knowledge of MiP. There was poor knowledge of the complications of MiP in mothers, with 27% unaware of any complications. Majority (51.6%) of them did not know the complications of malaria in the fetus. Better educated respondents had statistically significant better knowledge of MiP (P = 0.001). Only two-fifths of the respondents (39.8%) agreed that MiP can lead to death of the fetus. Most (41.9%) used insecticide spray and coils in the prevention of MiP, whereas only 36.9% used intermittent preventive treatment. Only 24.1% used insecticide-treated nets and almost 20% used no form of prevention.

Conclusion:

Respondents’ knowledge, perception, and preventive practices for MiP were not satisfactory. Public health education on MiP should be intensified at the community level in order to improve knowledge and prevention and also to correct misconceptions.

Regular Antenatal Attendance and Education Influence the Uptake of Intermittent Preventive Treatment of Malaria in Pregnancy: A Cross-Sectional Study at the University Hospital, Kumasi, Ghana

Background

The World Health Organization (WHO) recommends the use of Insecticide Treated Bed-Nets and Intermittent Preventive Treatment (IPT) with Sulphadoxine-Pyrimethamine (SP) as interventions in curbing malaria during pregnancy. However, increasing evidence shows a gap in coverage where not all pregnant women receive the recommended SP dose. This study evaluated the factors influencing uptake of IPTp-SP among pregnant women in Kumasi, Ghana.

Methodology

This cross-sectional study was conducted among 280 pregnant women attending the Kwame Nkrumah University of Science and Technology Hospital in Kumasi, Ghana. Validated structured questionnaires were administered to obtain sociodemographic, medical/reproductive information, and IPTp-SP uptake among participants. Statistical analyses were performed using IBM SPSS 25.0 statistics.

Results

The mean age of respondents was 29.7±4.9 years. Of the 280 women interviewed, 74.6% attended the antenatal care (ANC) clinic at least four times with only 31.8% completing the recommended doses. Tertiary education [aOR=3.15, 95% CI (0.94 -10.97), and p=0.042] and ≥ 4 ANC visits [aOR=24.6, 95% CI (5.87-103.07), p<0.0001] had statistically significant higher odds of completing the recommended IPTp-SP dose. However, participants employed by the formal sector [aOR=0.28, 95% CI (0.09 - 0.79), p=0.016] and participants with more than four children [aOR=0.14, 95% CI (0.03 - 0.63), and p=0.011] had statistically significant lower odds of completing the recommended IPT dose.

Conclusion

ANC attendance is critical in IPTp uptake. The results emphasize the need for the Health Policy Makers in Kumasi to encourage pregnant women, especially women working in the formal sector and women having more than four children to patronize ANC attendance to ensure high coverage of the recommended IPTp dose.
