Pearson correlations between anthropometric variables in the Women's Health Initiative, 1998–2006^*

	Body mass index†	Waist:hip ratio
Waist:hip ratio	0.34
Waist circumference	0.83	0.67
Height	−0.08	−0.05
Weight	0.93	0.31
Weight at age 18 years‡	0.29	0.07
Weight at age 35 years‡	0.53	0.19
Weight at age 50 years‡	0.71	0.26

^*All correlations were significant at the p < 0.0001 level.

^†Measured weight (kg) divided by the square of measured height (cm)².

^‡Self-reported information on weight at these ages was available only in the Observational Study; other variables were based on measurements taken at baseline in the total population.
