All trends were significant at P < 0.0001 by simple least-squares regression analyses. Sample sizes for waist circumference were: 8,525 for <22.5 kg/m2, 10,823 for 22.5–25 kg/m2, 5,587 for 25–27.5 kg/m2, and 2,149 for ≥27.5 kg/m2; and for chest circumference were: 7,301 for <22.5 kg/m2, 9,368 for 22.5–25 kg/m2, 4,908 for 25–27.5 kg/m2, and 1,901 for ≥27.5 kg/m2.
