RESUMO
Background: Seasonal malaria chemoprevention (SMC) has been widely expanded in Mali since its recommendation by the the World Health Organization in 2012. SMC guidelines currently target children between three months and five years of age. The SMC initiative has been largely successful. Children at least five years of age are not currently covered by current SMC guidelines but bear a considerable portion of the malaria burden. For this reason, this study sought to determine the feasibility and effectiveness for extending SMC to children aged 5-9 years. Methods: A non-randomized, pre-post study was performed with an intervention district (Kita) and a comparison district (Bafoulabe). Children aged 3-59 months received SMC in both comparison districts, and children aged 60-120 months received SMC in the intervention district. SMC was delivered as sulfadoxine-pyriméthamine plus amodiaquine (SP-AQ) at monthly intervals from July to October in 2017 and 2018 during the historical transmission seasons. Baseline and endline cross-sectional surveys were conducted in both comparison districts. A total of 200 household surveys were conducted at each of the four monthly SMC cycles to determine adherence and tolerance to SMC in the intervention district. Results: In July 2017, 633 children aged 60-120 months old were enrolled at the Kita and Bafoulabe study sites (n = 310 and n = 323, respectively). Parasitemia prevalence was similar in the intervention and comparison districts prior the SMC campaign (27.7% versus 21.7%, p = 0.07). Mild anemia was observed in 14.2% children in Kita and in 10.5% of children in Bafoulabé. At the Kita site, household surveys showed an SMC coverage rate of 89.1% with a response rate of 93.3% among child caregivers. The most common adverse event reported by parents was drowsiness (11.8%). One year following SMC implementation in the older age group in Kita, the coverage of three doses per round was 81.2%. Between the baseline and endline surveys, there was a reduction in parasitemia prevalence of 40% (OR = 0.60, CI: 0.41-0.89). Malaria molecular resistance was low in the intervention district following the intervention. A significant reduction in the prevalence of parasitemia in children 60 to 120 months was observed in the intervention district, but the prevalance of clinical malaria remained relatively constant. Conclusion: This study shows that the prospect of extending SMC coverage to children between five and nine years old is encouraging. The reduction in the parasitemia could also warrant consideration for adapting SMC policy to account for extended malaria transmission seasons.
RESUMO
Background: Neonatal deaths contribute to nearly half (47%) of under-five mortality globally and 67% in Bangladesh. Despite high neonatal mortality, care-seeking from qualified providers for newborn danger signs remains low. Identification of direct and indirect factors and their pathways affecting care-seeking will help to design a well-targeted intervention. This study assessed the direct, indirect, and total effect of the predictive factors on neonatal care-seeking in Bangladesh. Materials and methods: This was a cross-sectional baseline household survey conducted in 14 districts of Bangladesh in 2019 with 17,251 recently delivered women (RDW) with a live birth outcome in the preceding 15 months. We used a two-stage stratified cluster sampling process to select the samples from 14 districts. We investigated the inter-relationship of maternal background characteristics, maternal health utilizations, child/neonate factors, health service delivery-related factors and newborn danger sign knowledge with newborn care-seeking practices and estimated the direct, indirect, and total effects using Generalized Structural Equation Modeling (GSEM) and mediation analysis. p-value = 0.05 was considered statistically significant. The result of the mediation analysis was reported in Log Odds (LOD). The positive LOD (LOD > 0) implies a positive association. Results: Half of the mothers (50.8%) reported a neonatal illness and among them, only 36.5% mothers of sick neonates sought care from qualified providers. Our mediation analysis showed that maternal health utilization factors, i.e., 4 + antenatal care visits (ANC) from a qualified provider (LOD: 0.63, 95% CI: 0.49, 0.78), facility delivery (LOD: 0.74, 95% CI: 0.30, 1.17) and postnatal care (PNC) from a qualified provider (LOD: 0.50, 95% CI: 0.21, 0.78) showed the highest total effect over other factors domains, and therefore, were the most important modifiable predictors for qualified neonatal care-seeking. Other important factors that directly and/or indirectly increased the chance of newborn care-seeking from qualified providers were household wealth (LOD: 0.86, 95% CI: 0.70, 1.02), maternal education (LOD: 0.48, 95% CI: 0.32, 0.63), distance to nearest health facility (LOD: 0.20, 95% CI: 0.10, 0.30), community health worker's (CHWs) home visits during ANC (LOD: 0.24, 95% CI: 0.13, 0.36), neonatal danger sign counseling after delivery (LOD: 0.20, 95% CI: 0.06, 0.34) and women's knowledge of neonatal danger signs (LOD: 0.37, 95% CI: 0.09, 0.64). Conclusion: The inter-relationship and highest summative effect of ANC, facility delivery, and PNC on newborn care-seeking suggested the maternal care continuum altogether from ANC to facility delivery and PNC to improve care-seeking for the sick newborn. Additionally, referral training for unqualified providers, targeted intervention for poorer households, increasing CHWs home visits and neonatal danger sign counseling at the facility and community should also be considered.
