Comparisons of NSHD anthropometry against corresponding ordinal MWS body size variables at various ages. Means and 95% confidence intervals of NSHD anthropometric variables are plotted according to categories of MWS body size variables. (A) NSHD BMI measured at age 11 versus MWS relative body size at age 10; (B) NSHD BMI reported at age 20 versus MWS clothes size at age 20; (C) NSHD BMI measured at age 53 versus MWS clothes size in middle age; (D) NSHD waist circumference measured at age 53 versus MWS clothes size in middle age; (E) NSHD chest circumference measured at age 53 versus MWS bra band size in middle age. Spearman correlations (r) are indicated for each pair of NSHD and MWS variables.
