1. Waist circumference at iliac crest Note: Take the measurement to the nearest 0.1 cm. Waist Circumference at Iliac Crest 1:______cm Waist Circumference at Iliac Crest 2:______cm

A third measurement should be taken if the first two measurements differed by >1.0 cm (1/4") for participants 12 years or older or > 0.5 cm (1/8") for participants 11 years and younger. Waist Circumference at Iliac Crest 3:______cm

If it is necessary to take a third measurement, the two closest measurements are averaged. Should the third measurement fall equally between the first two measurements, all three should be averaged. Average Waist Circumference at Iliac Crest:______cm

2. Waist circumference measured at the narrowest part of the torso (natural waist) Note: Round down to the nearest half centimeter. Waist Circumference at Natural Waist 1:______cm Waist Circumference at Natural Waist 2:______cm

A third measurement should be taken if the first two measurements differed by >1.0 cm (1/4") for participants 12 years or older or > 0.5 cm (1/8") for participants 11 years and younger. Waist Circumference at Natural Waist 3:______cm

If it is necessary to take a third measurement, the two closest measurements are averaged. Should the third measurement fall equally between the first two measurements, all three should be averaged. Average Waist Circumference at Natural Waist:______cm

3. Waist circumference at the umbilicus Note: Record measurement to the nearest 1/4 inch, rounding down. Waist Circumference at Umbilicus 1:______cm Waist Circumference at Umbilicus 2:______cm
