Chapter 69. Pregnancy and Lactation
A 30-year-old woman wants to start vitamins before she becomes pregnant sometime next year. She takes acetaminophen for headaches, her vaccines are current, and she consumes about 600 mg of caffeine per day. Which component of a multivitamin will decrease the risk of neural tube defects in her baby?
Answer d is correct: Adequate intake of folic acid decreases the incidence of neural tubal defects by 50% to 70%. Neural tube defects can occur in the first 4 weeks of development. It is important that all women of childbearing age take 400 to 800 mcg of folic acid daily. Some women with a higher risk of a pregnancy affected by neural tubal defects may require 4 mg daily.
Answer a is incorrect: Calcium plays an important role in bone health. A fetus will require 30 grams of calcium for a full term pregnancy. Recommended daily calcium intake is 1300 mg for ages 14 to 18 years and 1000 mg for women 19 to 50 years.
