Vitamin A deficiency among pregnant women in Ethiopia: a systematic review and meta-analysis.

BACKGROUND: Vitamin A deficiency (VAD) during pregnancy is a public health challenge in low-income countries. There are inconsistent findings that can affect policy in planning appropriate intervention. This systematic review and meta-analysis were conducted to summarize the evidence in order to identify existing gaps and propose strategies to reduce VAD during pregnancy in Ethiopia. METHODS: This study included published and unpublished observational studies searched from different databases (PubMed, CINHAL [EBSCO], Embase, Google Scholar, Directory of Open Access Journals, Web of Sciences, MEDLINE, Cochrane Library, Scopus, Google Search and MedNar). Statistical analysis was conducted using Stata version 14 software. Heterogeneity and publication bias were assessed. Forest plots were used to present the pooled prevalence using the random effects model. RESULTS: A total of 37 618 pregnant women from 15 studies were included. The overall pooled prevalence of VAD was 29% (95% confidence interval 21 to 36) with I2=99.67% and p<0.001. Socio-economic and sociodemographic factors were identified as affecting vitamin A deficiencies among pregnant women. CONCLUSIONS: Nearly one-third of pregnant women in Ethiopia had VAD. Strengthening intervention modalities that aimed to increase the uptake of vitamin A-rich foods can avert VAD among pregnant women in Ethiopia.

Use of tranexamic acid in decreasing blood loss during and after delivery among women in Africa: a systematic review and meta-analysis.

BACKGROUND: Africa is a developing continent with a high maternal mortality rate. It is beneficial to implement interventions that alleviate the problem. As a result, this systematic review and meta-analysis was carried out to summarize evidence that will assist concerned bodies in proposing strategies to reduce maternal mortality due to post-partum hemorrhage. METHODS: This systematic review and meta-analysis includes randomized control trials (RCT) studies searched from various databases (PubMed, Web of Sciences, SCOPUS, African Journal Online, Clinical trials, and African indexes Medics). Data synthesis and statistical analysis were conducted using a combination of review manager 5.3 and STATA Version 14 software. The effect measure utilized was the standardized mean difference for estimated mean blood loss and mean hemoglobin level. RESULTS: This systematic review and meta-analysis includes a total of 3308 women. The pooled standardized mean difference showed that tranexamic acid statistical significantly reduced the estimated amount of blood loss after vaginal delivery (standardized mean difference with 95% CI - 0.93 [- 1.45, - 0.41]) and during and after cesarean delivery (standardized mean difference with 95% CI - 1.93 [- 2.40, - 1.47]). CONCLUSION: Tranexamic acid has been found to be a good choice for reducing blood loss during and after delivery in Africa regardless of the mode of delivery. Tranexamic acid had no effect on hemoglobin levels before and after delivery. To reduce maternal mortality due to post-partum hemorrhage, it is critical to implement and strengthen interventions aimed at increasing tranexamic acid uptake in Africa.
