Prevalence and Determinants of Anemia During the Third Trimester of Pregnancy
Condition: Anemia of Pregnancy
MeSH terms: Anemia
Study type: Observational

Summary: 
      This cross-sectional study was conducted on 383 pregnant women who attended the antenatal
      care clinic during their third trimester at Beni-Suef University Hospital.

      A proper history was taken from each participant. All women were subjected to routine
      antenatal care, including physical examinations, ultrasound examinations, and routine
      laboratory tests.

      According to WHO criteria, anemia was diagnosed with a hemoglobin level of less than 11.0
      g/dl. Anemia was further divided into three degrees; mild with hemoglobin level 10-10.9 g/dl,
      moderate with hemoglobin level 7-9.9 g/dl, and severe with hemoglobin level < 7.0 g/dl.
    

Detailed description: 
      This cross-sectional study was conducted on 383 pregnant women who attended the antenatal
      care clinic during their third trimester at Beni-Suef University Hospital.

      A proper history was taken from each participant regarding age, educational level, residency
      (urban or rural), occupation, family income, frequency of antenatal visits, obstetric
      history, medical history, and surgical history. Nutritional history is taken to detect the
      frequency intake of meat/month, chicken/week, fish/week, fruits/week, vegetables/week, and
      tea/day. History of iron supplements intake was taken. All women were subjected to routine
      antenatal care, including a physical examination (e.g., measuring blood pressure),
      ultrasound, and umbilical artery Doppler examination. A blood sample was taken from each
      enrolled woman for standard laboratory tests such as complete blood picture, blood group, RH
      type, and blood sugar test if there is a risk. A urine sample was taken for urine analysis.
      Blood from each participant was drawn from the cubital vein into appropriate blood collection
      tubes using vacuum tube needles (Becton Dickinson Medical Devices Co. Ltd., Franklin Lakes,
      USA). K2EDTA tubes were used for CBC. Samples were transported and tested within 4 hours
      after collection. Measured CBC parameters included RBC, HGB, HCT, mean corpuscular volume
      (MCV), mean corpuscular hemoglobin (MCH), MCH concentration (MCHC), platelet count (PLT),
      WBC, and WBC differentials, including percentages and absolute counts of neutrophils (NEUT%
      and NEUT), lymphocytes (LYM% and LYM), monocytes (MONO% and MONO), basophils (BASO% and
      BASO), and eosinophils (EO% and EO).

      According to WHO criteria, anemia was diagnosed with a hemoglobin level of less than 11.0
      g/dl. Anemia was further divided into three degrees; mild with hemoglobin level 10-10.9 g/dl,
      moderate with hemoglobin level 7-9.9 g/dl, and severe with hemoglobin level < 7.0 g/dl.
