Answer

Answer key: Pregnancy Weight Gain worksheet

1. Recommended total gain (singleton): 7–11.5 kg
1. Find your BMI before pregnancy: weight in kilograms divided by height in meters, squared
  $\frac{66}{{1.6}^{2}}$ $= 25.8$
2. Look up your BMI group. The 2009 IOM guidelines give a total gain range for each one
  $Overweight (BMI 25.0–29.9) →$ $= 7–11.5 kg$
3. After week 13, the range climbs at a steady pace from the first-trimester gain to the full range at week 40
  $low: 0.5 + (7 - 0.5) \times \frac{(15 - 13)}{27}; high: 2 + (11.5 - 2) \times \frac{(15 - 13)}{27}$ $= 1–2.7 kg$
4. Take your weight before pregnancy away from your current weight to get your gain so far. Then compare it with this week's range
  $80 kg - 66 kg$ $= 14 kg$
2. Recommended total gain (singleton): 25–35 lb
1. Change height to meters and your weight before pregnancy to kilograms, since BMI uses metric units (1 in = 2.54 cm, 1 lb = 0.45359237 kg)
  $(5 \times 12 + 4) \times 0.0254 = 1.6256 m; 120 lb \times 0.45359237 = 54.431 kg$
2. Find your BMI before pregnancy: weight in kilograms divided by height in meters, squared
  $\frac{54.431}{{1.6256}^{2}}$ $= 20.6$
3. Look up your BMI group. The 2009 IOM guidelines give a total gain range for each one
  $Normal weight (BMI 18.5–24.9) →$ $= 25–35 lb$
4. After week 13, the range climbs at a steady pace from the first-trimester gain to the full range at week 40
  $low: 1.1 + (25 - 1.1) \times \frac{(24 - 13)}{27}; high: 4.4 + (35 - 4.4) \times \frac{(24 - 13)}{27}$ $= 10.8–16.9 lb$
5. Take your weight before pregnancy away from your current weight to get your gain so far. Then compare it with this week's range
  $160 lb - 120 lb$ $= 40 lb$
3. Recommended total gain (singleton): 11–20 lb
1. Change height to meters and your weight before pregnancy to kilograms, since BMI uses metric units (1 in = 2.54 cm, 1 lb = 0.45359237 kg)
  $(4 \times 12 + 5) \times 0.0254 = 1.3462 m; 140 lb \times 0.45359237 = 63.503 kg$
2. Find your BMI before pregnancy: weight in kilograms divided by height in meters, squared
  $\frac{63.503}{{1.3462}^{2}}$ $= 35$
3. Look up your BMI group. The 2009 IOM guidelines give a total gain range for each one
  $Obese (BMI 30 or more) →$ $= 11–20 lb$
4. After week 13, the range climbs at a steady pace from the first-trimester gain to the full range at week 40
  $low: 1.1 + (11 - 1.1) \times \frac{(28 - 13)}{27}; high: 4.4 + (20 - 4.4) \times \frac{(28 - 13)}{27}$ $= 6.6–13.1 lb$
5. Take your weight before pregnancy away from your current weight to get your gain so far. Then compare it with this week's range
  $190 lb - 140 lb$ $= 50 lb$
4. Recommended total gain (singleton): 11.5–16 kg
1. Find your BMI before pregnancy: weight in kilograms divided by height in meters, squared
  $\frac{75}{{1.9}^{2}}$ $= 20.8$
2. Look up your BMI group. The 2009 IOM guidelines give a total gain range for each one
  $Normal weight (BMI 18.5–24.9) →$ $= 11.5–16 kg$
3. After week 13, the range climbs at a steady pace from the first-trimester gain to the full range at week 40
  $low: 0.5 + (11.5 - 0.5) \times \frac{(24 - 13)}{27}; high: 2 + (16 - 2) \times \frac{(24 - 13)}{27}$ $= 5–7.7 kg$
4. Take your weight before pregnancy away from your current weight to get your gain so far. Then compare it with this week's range
  $75 kg - 75 kg$ $= 0 kg$
