claimFactors associated with anaemia in pregnancy include higher parity, later trimester of pregnancy, low socioeconomic status, and inadequate nutrient intake.
measurementThe prevalence of anaemia in pregnancy in Nigeria is 61.1%, with regional variations ranging from 55.2% in the South-West to 71.1% in the South-East region (p = 0.038).
claimSociodemographic and obstetric factors, specifically being single, being in the second or third trimester of pregnancy, and having a lower level of education, were associated with an increased risk of anaemia in pregnancy.
claimEducation is associated with a lower risk of anaemia in pregnancy because it improves health literacy and promotes knowledge-seeking behavior regarding health.
measurementIn Nigeria, women with tertiary education had 64% lower odds of anaemia in pregnancy (p = 0.002) compared to women with no formal education, and not being married increased the odds of anaemia compared to being married or cohabiting.
claimThe association between dietary diversity and anaemia in pregnancy observed in the study was no longer evident when sociodemographic factors were controlled for.
procedureThe study defined anaemia in pregnancy as a haemoglobin concentration of less than 11g/dl, irrespective of the trimester of pregnancy.
measurementCompared to the North-West region of Nigeria, the prevalence of anaemia in pregnancy was significantly higher in the North Central region (aOR: 1.90; 95% CI: 1.14–3.16).
claimIn the study 'Dietary diversity insufficiently explains differences in prevalence of anaemia in pregnancy across regions', the association between higher household wealth index and lower odds of anaemia was statistically significant in the unadjusted model but lost significance in the adjusted model, potentially due to residual confounding.
measurementThe prevalence of anaemia in pregnancy in Nigeria (61%) exceeds global WHO-reported prevalences for South-East Asia (48%) and Sub-Saharan Africa (46%).
claimAnaemia in pregnancy is linked to poor dietary intake, specifically micronutrient deficiencies including iron, folate, vitamin B12, and zinc.
claimAnaemia in pregnancy is associated with adverse outcomes for both mother and baby, including increased risks of preterm birth, postpartum haemorrhage, foetal growth restriction, low birth-weight, intrauterine foetal death, and maternal death.
measurementThe prevalence of anaemia in pregnancy in Nigeria is 61%, with statistically significant variation across regions.
measurementThe prevalence of anaemia in pregnancy is above 40% in low- and middle-income countries (LMICs), compared to below 20% in high-income countries.
claimThe effect of education on anaemia in pregnancy is unlikely to be driven by financial means, as the study adjusted for household wealth in its analysis.
claimVitamin A deficiency causes anaemia in pregnancy by impairing iron mobilization from the liver and spleen, making iron unavailable for erythropoiesis.
measurementFacility-based studies in Nigeria have indicated that the prevalence of anaemia in pregnancy varies significantly by region, ranging from 32.5% in Ogun state (South-West) to 61.1% in Akwa Ibom state (South-South).
claimA study using nationally representative data in Nigeria found no evidence of effect modification between region and MDD-W regarding anaemia in pregnancy (p = 0.154) based on a postestimation comparison of models with and without an interaction term.
measurementThe prevalence of anaemia in pregnancy in Nigeria (61%) is higher than in India (50%) and comparable to Mali (59%).
claimAnaemia in pregnancy is a non-communicable disease targeted by the United Nations Sustainable Development Goal (SDG) 3, which aims to reduce maternal mortality.
claimThe prevalence of anaemia in pregnancy has remained high despite routine iron supplementation, indicating a need for diverse prevention strategies.
measurementThe prevalence of anaemia in pregnancy is high in Nigeria and varies across regions, with the highest prevalence observed in the South-East region.
measurementThere was a significant crude association between minimum dietary diversity for women (MDD-W) and anaemia in pregnancy (OR: 0.78; 95% CI: 0.60 - 0.99), but this association was lost when confounders were included in the analysis (aOR: 0.85; 95% CI: 0.66-1.10).
claimThe association between Minimum Dietary Diversity for Women (MDD-W) and anaemia in pregnancy lost statistical significance when confounders were considered in the study analysis.
claimThe study is population-based and uses a sample representative of Nigeria to provide insight into how Minimum Dietary Diversity for Women (MDD-W) affects the prevalence of anaemia in pregnancy.
claimFactors such as food security (availability and accessibility), seasonality of food availability, genetic haemoglobin disorders, and maternal and community characteristics likely explain the disparity in the prevalence of anaemia in pregnancy across regions in Nigeria.
claimRegion does not differentiate the effect of dietary diversity on anaemia in pregnancy, but it may distort the association between them.
claimThe researchers concluded that region is not an effect modifier of the association between minimum dietary diversity for women (MDD-W) and anaemia in pregnancy, and that dietary diversity alone does not explain the differences in anaemia prevalence across regions in Nigeria.

claimThe study titled 'Dietary diversity insufficiently explains differences in prevalence of anaemia in pregnancy' determined the association between dietary diversity and the prevalence of anaemia in pregnancy.
claimThe study titled 'Dietary diversity insufficiently explains differences in prevalence of anaemia in pregnancy' concludes that dietary diversity is an insufficient explanation for the differences in the prevalence of anaemia in pregnancy.
claimThe study titled 'Dietary diversity insufficiently explains differences in prevalence of anaemia in pregnancy' compared the prevalence of anaemia in pregnancy across different regions in Nigeria.
