Question

Sadie is a 37-year-old teacher in her 20th week of pregnancy. She is 68 inches tall and weighs 195 pounds. Her pre-pregnancy weight was 180 pounds. During her first pregnancy 2 years ago, she gained 50 pounds. She gave birth to an infant weighing 9 pounds, 2 ounces. Her doctor has recommended that she keep her weight gain within the recommended range. She likes to swim but has not been exercising regularly since she found out she was pregnant. She has had morning sickness through much of this pregnancy and says that she feels better when she eats starchy foods such as white bread, potato chips, and refined pasta. She reports recent problems with constipation and is seeking ways to relieve her discomfort.
Required:
a. Calculate Sadie's body mass index (BMI) based on her pre-pregnancy weight.
b. Based on her pre-pregnancy weight, if she is carrying a single baby, how much weight should Sadie gain during her pregnancy?
c. By the 20th week of pregnancy, how much weight should Sadie gain?

Answer 1

(a) 29.4 is Sadie's body mass index (BMI) based on her pre-pregnancy weight.

(b) 15 to 25 lbs is the amount of weight should Sadie gain during her pregnancy if she is carrying a single baby.

(c) 6.7 lbs is the amount of weight Sadie should gain by the 20th week of pregnancy.

Adult men and women can use the body mass index (BMI), a measurement of body fat based on height and weight.

Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms (or pounds) by their height in metres squared (or feet).

High body fatness may be indicated by a high BMI. BMI does not make a body fat or health diagnosis for an individual, but it does screen for weight categories that may cause health issues.

You are about five months along in your pregnancy at 20 weeks. Most women gain between two and four pounds during the first three months, and then one pound every month until the conclusion of the pregnancy.

With the BMI of 29.4 it is suggested that one should gain 15-25 lbs of weight during the pregnancy and about 6.7 lbs weight by the 20th week of pregnancy.
