[PMID: 38459499 PMCID: PMC10921604 DOI: 10.1186/s12884-024-06355-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Accepted: 02/18/2024] [Indexed: 03/10/2024] Open
Abstract
In sub-Saharan Africa, malaria, which remains a major public health burden, has a prevalence of 9 to 28% and malaria in pregnancy is associated with severe adverse outcomes for the mother and her baby. Here, we sought to determine the predictors of birth weight in a cohort of 140 women with malaria in pregnancy, who were recruited at the Webuye County hospital in Western Kenya. All study participants underwent malaria diagnosis through microscopic examination of blood smear samples and were grouped into the malaria-positive and malaria-negative groups. Both groups were followed up beginning at the first antenatal visit (March 2022) until delivery (December 2022) and various data, including demographic, parity, gravidity, socioeconomic, maternal and fetal outcomes were collected. Data analyses were done using SPSS version 27. Chi-square and Fisher's Exact tests were used for bivariate and relative risk analyses at a p-value of ≤0.05 (95%) confidence level. Most of the participants were aged 18-25 years, were primigravidas and married, had secondary school-level education, earned 20-30 thousand Kenya shillings, resided in rural areas, and were in the second trimester. There were 6 (4.6%) cases of low birth weight, 3 (4.5%) in the malaria-negative group and 3 (4.7%) in the malaria-positive group. During pregnancy, 41 (31.5%) were anaemic, 5 (3.8%) were HIV-positive, 5 (3.8%) had preeclampsia, and 2 (1.5%) had gestational diabetes. Our analyses show that confounding factors like anaemia, HIV, pre-eclampsia and gestational diabetes did not influence birthweight (p ≥ 0.923). The malaria-positive and malaria-negative groups did not differ significantly with regard to the low birth weight (relative risk: 0.999, 95% confidence interval: 0.926-1.077). Marital status, gestational age, and area of residence were associated with malaria p ≤ 0.001, ≤ 0.001 and 0.028 respectively. In both groups, 124 of the 140 deliveries had normal birth weights and of these 63 (95.4%, n = 70) were in the malaria-negative group, whereas 61 (95.3%, n = 70) belonged to the malaria-positive group.

A malaria knowledge, attitudes and practice survey in a rural community in Guinea. Malar J 2022; 21:329. [PMCID: PMC9663183 DOI: 10.1186/s12936-022-04357-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 11/01/2022] [Indexed: 11/16/2022] Open
Abstract
Abstract
Background
Malaria is the top public health problem in the Republic of Guinea, with more than 4 million cases and 10,000 deaths in 2021 among a population of approximately 13 million. It is also the second highest cause of death there. The purpose of this quantitative survey in a rural area of Guinea was to understand knowledge, attitudes, and practices (KAP) about malaria and to assess water and sanitation practices among community members.
Methods
In 2016, the authors conducted a cross-sectional household survey in Timbi-Touni, Guinea using community workers. The survey included respondent demographic characteristics, malaria knowledge, child health, water and sanitation, and health services access. Malaria knowledge and sleeping under bed nets were the primary outcome variables and multiple logistic regression was used to determine odds ratios.
Results
Majority of the respondents were women (89.41%) and had never been to school (71.18%). Slightly more than half the children were reported to have ever had malaria and 45% reported to have ever had diarrhoea. There was no statistically significant association between gender or level of education and malaria knowledge. Eighty six percent of respondents had received a free bed net during national campaigns and 61% slept under a bed net the night before the survey. Knowing mosquitoes to be the cause of malaria and receiving free bed net were significantly associated with sleeping under a bed net. There was no statistically significant association between drinking water source and malaria or diarrhoea.
Conclusions
Both malaria and diarrhoea were considered to be serious illnesses for adults and children by nearly all respondents. Receiving free bed nets and having correct knowledge about malaria were the greatest predictors of sleeping under a bed net. Insights from this detailed KAP survey—such as focusing on radio to transmit malaria prevention information and reinforcing free malaria treatments—can guide policy makers and practitioners who design and implement malaria control and prevention measures in Guinea.

Mwangu LM, Mapuroma R, Ibisomi L. Factors associated with non-use of insecticide-treated bed nets among pregnant women in Zambia. Malar J 2022; 21:290. [PMID: 36221068 PMCID: PMC9555102 DOI: 10.1186/s12936-022-04313-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Accepted: 09/23/2022] [Indexed: 12/04/2022] Open
Abstract
Background Despite the Zambian government’s efforts to ensure 80% use of insecticide-treated nets (ITNs) among pregnant women, ITN use remains critically low. Only 49% of pregnant women reported sleeping under an ITN in 2018 in the country. This study aims to determine the prevalence of, and the factors associated with the non-use of ITNs among pregnant women in Zambia. Methods This study was a secondary analysis of the data collected during the 2018 Zambian Demographic and Health Survey. One thousand one hundred and thirty-eight (1 138) pregnant women were included in the study. The prevalence of the non-use of ITNs was computed and univariable and multivariable logistic regression models were fitted to determine the factors associated with the non-use of ITNs in the study population. Results The study found that 578 (50.8%) pregnant women reported not using an ITN the night before the survey. The results of the multivariable logistic regression indicated that, primary level education (OR = 2.13, 95% CI 1.23–3.68), ITN per household member (OR = 0.01, 95% CI 0.00–0.02), parity (OR = 0.83, 95% CI 0.70–0.99), moderate malaria prevalence provinces (OR = 0.34, 95% CI 0.23–0.50), high malaria prevalence provinces (OR = 0.26, 95% CI 0.18–0.39) and currently in a union (OR = 0.52, 95% CI 0.30–0.88) were significantly associated with the non-use of ITNs. Conclusion This study showed a high prevalence of the non-use of ITNs among pregnant women in Zambia. Factors found to be associated with the non-use of ITNs in the study population are: ITN per household member, parity, education, marital status and malaria prevalence provinces. Addressing the identified factors will require intensification of ITN programming and other malaria preventive measures.

Abstract
Malaria is one of the leading causes of mortality and morbidity in Guinea. The entire country is considered at risk of the disease. Transmission occurs all year round with peaks occurring from July through October with Plasmodium falciparum as the primary parasite species. Chloroquine (CQ) was the first-line drug against uncomplicated P. falciparum in Guinea until 2005, prior to the adoption of artemisinin-based combination therapy (ACT). In this review, data on therapeutic efficacy of CQ and artemisinin-based combinations reported in published literature is summarized. Against CQ, a failure rate of 27% (12/44) was reported in a study in 1992; a median failure rate of 15.6% [range: 7.7–28.3; 8 studies] was observed during 1996–2001, and 81% (17/21) of the patients failed to clear parasitaemia in a study conducted in 2007. For artemisinin-based combinations, three published studies were identified (1495 patients; 2004–2016); all three studies demonstrated day 28 polymerase chain reaction corrected efficacy > 95%. One study characterized kelch-13 mutations (389 tested; samples collected in 2016) with no evidence of mutations currently known to be associated with artemisinin resistance. The impact of the ongoing COVID-19 pandemic and widespread usage of counterfeit medicines are immediate challenges to malaria control activities in Guinea.

[PMID: 33062290 PMCID: PMC7552502 DOI: 10.1186/s40794-020-00121-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Accepted: 09/28/2020] [Indexed: 12/03/2022] Open
Abstract
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.
