Study on Haemoglobin Concentration During First Trimester of Pregnancy: Analysis with Folic Acid Supplementation
Abstract: During pregnancy, haemoglobin concentration is an important indicator of maternal health. The first trimester is a crucial period when physiological changes, such as plasma volume expansion, can affect haemoglobin levels. Folic acid is routinely prescribed to support red blood cell formation and prevent anaemia during early pregnancy. This study was designed to evaluate the variations in haemoglobin levels during the first trimester of pregnancy and to examine the impact of folic acid supplementation. A paired-sample design was adopted to compare haemoglobin levels at the beginning and end of the first trimester among 50 pregnant women who were receiving folic acid supplementation. The mean, standard deviation, and t-values were calculated, and statistical significance was tested using the paired t-test. The mean haemoglobin concentration at the beginning of the first trimester was 11.63 g/dl, which reduced to 11.32 g/dl by the end of the trimester. The mean change of 0.31 g/dl was found to be statistically significant (t = 2.87, df = 49, p
