procedureThe study defined anaemia in pregnancy as a haemoglobin concentration of less than 11g/dl, irrespective of the trimester of pregnancy.
procedureThe study compared regional prevalence of anaemia using the Chi-square test and compared regional haemoglobin concentrations using the Student’s t-test.
measurementThe study defined the primary outcome as the presence of anaemia, measured using a Hemocue 301 device, defined as a haemoglobin concentration of less than 11g/dl regardless of the trimester of pregnancy.
measurementAmong the sub-population of pregnant women with anaemia, the mean haemoglobin concentration was 9.5 g/dl (95% CI: 9.4-9.6 g/dl), which did not differ significantly across regions (p = 0.689).
claimConsumption of eggs improves haemoglobin concentration and serum ferritin levels because eggs contain heme and non-heme iron.
measurementThere was no statistically significant difference in the mean haemoglobin concentration among pregnant women across the six regions (p = 0.422).
measurementA total of 15,236 reproductive-aged women were invited for anaemia screening, of which 14,750 were screened, and 1,525 eligible pregnant women with valid haemoglobin concentration measurements were included in the final analysis.
measurementThe mean haemoglobin concentration among pregnant women drops significantly as the trimester advances, with the highest values observed in the first trimester and the lowest in the third trimester (p < 0.001 for the general pregnant population; p = 0.02 for the anaemic sub-group).
