| Head circumference z-score | 0.18 (0.97) | 0.23 (1.03) | 0.75 |
| Mid-upper arm circumference, cm | 14.92 (2.32) | 14.57 (2.07) | 0.31 |
| Mid-upper arm circumference z-score | 0.02 (0.80) | −0.09 (0.48) | 0.34 |

| Mid-thigh circumference, cm | 24.54 (4.92) | 23.91 (4.97) | 0.42 |
| Mid-thigh skinfold, mm | 16.63 (5.66) | 16.64 (6.11) | 0.99 |
| Mid-thigh muscle circumference, cm | 19.38 (4.06) | 18.75 (4.10) | 0.33 |
Note: When the non-z score measures were adjusted by age, sex, and race there was no difference in the means and P-values.
T-tests for independent samples were conducted to compare uninfected children exposed to HIV and controls.
Weight, length, and head circumference z-scores were adjusted for prematurity for only uninfected children exposed to HIV. Unadjusted comparisons produced similar results.
