FIGURE 2.

Third-trimester (33.8 ± 4.0 wk gestation) fetal femur and humerus lengths were measured and converted into z scores. Maternal dietary calcium intake and 25(OH)D status interacted to affect bone length outcomes. In adolescents with 25(OH)D ≤ 50 nmol/L, those who consumed ≥1050 mg Ca/d had significantly higher fetal femur z scores (*P = 0.019) and tended to have higher fetal humerus z scores (P = 0.116). Among adolescents who were 25(OH)D sufficient, no significant difference in fetal z scores was found between adolescents who consumed >1050 or <1050 mg Ca/d. 25(OH)D, 25-hydroxyvitamin D.
