ch. 15 maternal nutrition Flashcards
healthy people 2030 goal for maternal nutrition
increase the proportion of women delivering a live birth who had a healthy weight/BMI prior to pregnancy
- increase the proportion of women of childbearing potential with intake of atleast 400 mg of folic acid from fortified foods and dietary supplements
maternal weight (3)
- pre pregnancy weight (BMI going INTO the pregnancy)
- maternal weight gain
- factors that influence weight gain: age, parity, nutritional status
formula for BMI
(weight (Ibs)/height (in))^2 x 703^12
underweight pre pregnancy (1)
higher risk of:
- low birth weight (or growth restricted) babies
overweight/obese pre pregnancy (4)
higher risk of:
- gestational diabetes
- HTN
- preeclampisa
- complications during labor and birth
babies of obese women (6)
higher risk of:
- PTB
- cesarean birth
- macrosomia
- stillbirth
- congenital anomalies
- childhood obesity
maternal weight gain (underweight) (BMI, total weight gain, rates of weight gain)
BMI: <18
total weight gain: 28-40 Ibs
rates of weight gain in 2/3 trimester (Ib/week): 1 (1-1.3)
maternal weight gain (normal) (underweight) (BMI, total weight gain, rates of weight gain)
BMI: 18.5 - 24.9
total weight gain: 25-35
rates of weigh gain in 2nd/3rd trimester (Ib/week): 1 (0.8-1)
maternal weight gain (overweight) (underweight) (BMI, total weight gain, rates of weight gain)
BMI: 25.0 - 29.9
total weight gain: 15-25
rates of weight gain in 2nd/3rd trimester (Ib/week): 0.6 (0.5-0.7)
maternal weight gain (obese) (underweight) (BMI, total weight gain, rates of weight gain)
BMI: >30
total weight gain: 11-20
