An analogous interaction between maternal 25(OH)D and maternal calcium intake was also observed when calcium intake was partitioned by the Estimated Average Requirement for this age group (1100 mg/d). In adolescents consuming <1100 mg Ca/d, those with 25(OH)D >50 nmol/L had significantly higher fetal femur (*P = 0.019) and humerus (*P = 0.025) z scores, Among adolescents who consumed ≥1100 mg Ca/d, no significant differences in fetal long-bone z scores were found between adolescents who were 25(OH)D sufficient and those who were insufficient. 25(OH)D, 25-hydroxyvitamin D.
