An investigation of vitamin and mineral supplement recommendation among first-trimester pregnancies.

Background Healthy and balanced nutrition in pregnancy can affect the mother's and the fetus' health. Therefore, health professionals should provide information about this issue to pregnant women. The aim of the study was to examine the rate of vitamin and mineral supplement recommendation among first-trimester pregnant women. Methods The study sample consisted of 697 first-trimester pregnant women between 18 and 40 years of age. The pregnant women who registered to an obstetric outpatient clinic between January and June 2018 were retrospectively reviewed, and data were collected from patient medical records using a questionnaire. Results Physician's laboratory test orders from the women included the following: ferritin was 18.4%, mean corpuscular hemoglobin (MCH) was 99.7%, folic acid was 10.2%, vitamin D was 6.3%, vitamin B12 was 17.2% and calcium was 20.4%. All of the women's hemoglobin levels had been examined. A total of 58.8% of the women were recommended to take folic acid, 32.7% iron, 25.7% iodine, 18.8% calcium, 17.2% vitamin A, 21.1% vitamin B12, 17.4% vitamin C, 31.6% vitamin D and 17.5% vitamin E supplements. Conclusion It was determined that ferritin, vitamins B12 and D, calcium, folic acid, iron and iodine levels were not examined routinely in this study. Folic acid and iron supplementation were the most commonly suggested nutrient supplements in the first trimester.
