Abstract Background Vitamin D deficiency among pregnant women is a public health concern globally. In India, individual studies report high prevalence. However, lack of national data masks the true burden. This work determined the pooled prevalence of vitamin D deficiency among pregnant women in India through a systematic review of literature and meta-analysis. Methods Three different search engines yielded 15 eligible articles. Study quality was assessed by 10 different criteria and summary of study quality was categorized as per Cochrane standards. Meta-analysis was performed to estimate pooled prevalence of vitamin D deficiency among healthy pregnant women and heterogeneity among selected studies. A sample of n = 4088 was used to study the pooled prevalence among pregnant women. Results The random effects combined estimate was 32.35% (95% CI, (12.58–117.48). High heterogeneity (tau2 = 0.39, I2 = 100%) and high risk of bias was observed among the selected studies. The test for overall effect was observed to be z = 2.54(P = 0.01). Conclusion Pooled estimate > 30% emphasizes the need for screening through antenatal care services and initiate preventive measures to address the deficiency.

Background. Malaria during pregnancy remains a major public health concern in tropical and subtropical countries. Moreover, malaria is increasingly associated with unwanted pregnancy outcomes such as an increased risk of abortion, stillbirth, premature delivery, and low-birthweight infants. Since pregnant women are most vulnerable to malaria, implementation of the appropriate prevention and control measures among this group is very important. Therefore, the current review was designed to assess the prevalence of both symptomatic and asymptomatic malaria among pregnant women in Ethiopia.Method. In this systematic review and meta-analysis we have followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The databases used were PubMed, Google Scholar, HINARI, and Science Direct literature. Search terms used were “prevalence”, “malaria”, “pregnant women”, and “Ethiopia”. Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI) was used for critical appraisal of studies. The meta-analysis was conducted using STATA 14 software. The pooled meta-logistic regression was computed to present the pooled prevalence with a 95% confidence interval (CI).Result. Among a total of 10207 studies, seven studies were included in this analysis. The estimated pooled prevalence of malaria among pregnant women in Ethiopia was 12.72% (95% CI: 7.45, 17.98). In subgroup analysis, the prevalence of malaria showed a significant variation between asymptomatic and symptomatic cases, which was 7.83% (95% CI: 2.23, 13.43) and 17.97% (95% CI: 7.31, 28.92), respectively.Conclusion. The current systematic review and meta-analysis showed that the pooled prevalence of malaria among pregnant women was found to be relatively higher compared with the general population. Therefore, the existing prevention and control measures should be strengthen.

Background: Vitamin D deficiency among adolescents is an emerging public health priority as adolescence marks a period of rapid growth and the onset of the reproductive phase. However, lack of national prevalence data and intervention strategies is of public health concern. Objective: The objective of this study was to determine the pooled prevalence of vitamin D deficiency among adolescent girls in selected Indian states. Methods: A systematic literature review was performed using three different search engines. The searches yielded nine eligible articles. Study quality was assessed for 10 different criteria. Meta-analysis was performed to estimate pooled prevalence of vitamin D deficiency among adolescent girls and to assess the heterogeneity among selected studies. Results: A sample of n=1352 was used to study prevalence among adolescent girls. The random effects combined estimate for overall prevalence was 25.70% (95% CI 3.89–2137.9). High heterogeneity (tau2=1.71, I2=100%) was observed and seven out of nine studies showed low to moderate risk and two showed high risk of bias. The test for overall effect was observed to be Z=0.77 ( p=0.44). Conclusions: High prevalence of vitamin D deficiency among adolescent girls identifies the need to introduce screening of adolescents and introduce proven public-health interventions such as fortification of foods to address deficiency.

Studies shows that, normal to high serum 25(OH)D status appears to have some beneficial influence on the incidence and severity of some, though not all, types of infections. However, studies with vitamin D supplementation on young children produced conflicting results with respect to the level of vitamin D deficiency among common medical illnesses among children. Method: A systematic review of literatures from PubMed, CINAHL, Web of science, global health and Google scholar electronic databases was conducted to assess the pooled prevalence of vitamin D deficiency among healthy and sick children in sub-Saharan Africa. The data was extracted by two authors independently using standard data extraction format and STATA Version 14 was used for analysis. The heterogeneity of the studies was assessed by using I2 test. A random-effects model was used to estimate the pooled prevalence among both healthy and sick children. Presence of publication bias was checked using Funnel plot and Egger's test. Result: A total of 1212 articles were identified by the total search of utilized data bases of which 13 papers fulfilled the inclusion criteria and accessible with full document. The meta-analysis revealed that the pooled prevalence of vitamin D deficiency among healthy children in this study was 50.06% (95%CI 33.46%, 66.67%) with mean serum vitamin D level of 41.06 nm/L (CI range from 23.82nm/L to 58.31nm/L). The pooled prevalence among the sick children was 39.36% (CI 20.57%, 57.96%) with 66.96nm/L (95% CI 54.81nm/L, 79.11nm/L) mean concentration of vitamin D. Comparing the two level of the pooled prevalence, the prevalence among the healthy children was significantly higher compared to those who have common medical illnesses and the pooled mean concentration among the sick was much higher than the mean concentration among healthy children. Conclusion: The level of pooled prevalence among both group of population was significantly of public health concern and the prevalence among the healthy children was much higher among the sick children implying the need for reconsideration of available recommendations for the prevention of vitamin D deficiency

Abstract Insufficiency of vitamin D, during pregnancy, is a common cause of various pregnancy-related complications. Despite such insufficiency being frequently reported among South Asian pregnant women, the absence of systematic review and meta-analysis renders the true extent of this problem poorly characterized. In this systematic review, three main databases (PubMed, Scopus, and Google Scholar) were searched for original studies. We included original studies published between 1st January 2001 to 31st December 2019, conducted on pregnant women who lived in South Asian countries and reported the prevalence of vitamin D insufficiency among the study participants. Twenty studies with a total of 7,804 participants from four South Asian countries finally met our selection criteria. Overall pooled prevalence of insufficiency was 65% [95 % CI: 51% to 78%] with a significant heterogeneity (I2 = 99.37 %; p = 0.00). The average level of vitamin D ranged from 9 ng/mL to 24.86 ng/mL with a weighted mean of 16.37 ng/mL (weighted standard deviation 7.13 ng/mL). The highest prevalence of insufficiency was found in Pakistan (76%) followed by India (67%), Bangladesh (64%), and Nepal (14%). Results obtained in this study suggest that vitamin D insufficiency is highly prevalent among South Asian pregnant women. Being the first systematic review in this region, findings from this study will help in future studies and strengthen the evidence for policymakers to develop effective mitigation strategies.

The Relationship

BackgroundThere is conflicting evidence about the relationship between vitamin D deficiency and depression, and a systematic assessment of the literature has not been available.AimsTo determine the relationship, if any, between vitamin D deficiency and depression.MethodA systematic review and meta-analysis of observational studies and randomised controlled trials was conducted.ResultsOne case-control study, ten cross-sectional studies and three cohort studies with a total of 31 424 participants were analysed. Lower vitamin D levels were found in people with depression compared with controls (SMD = 0.60,95% Cl 0.23–0.97) and there was an increased odds ratio of depression for the lowest v. highest vitamin D categories in the cross-sectional studies (OR = 1.31, 95% CI 1.0–1.71). The cohort studies showed a significantly increased hazard ratio of depression for the lowest v. highest vitamin D categories (HR=2.21, 95% CI 1.40–3.49).ConclusionsOur analyses are consistent with the hypothesis that low vitamin D concentration is associated with depression, and highlight the need for randomised controlled trials of vitamin D for the prevention and treatment of depression to determine whether this association is causal.
