Previously we have reported an association between maternal vitamin D and offspring bone as measured by dual-energy X-ray absorptiometry. It is plausible that shared genetics might confound associations between maternal vitamin D in pregnancy and offspring bone measures. We aimed to determine whether such associations are independent of maternal bone quality. Data for this analysis were derived from 168 mother-child pairs who returned at the 11-year follow-up of the vitamin D in pregnancy study. Gestational 25-hydroxyvitamin D [25(OH)D] was assessed by radioimmunoassay in early pregnancy at recruitment (before 16 weeks gestation) and later in pregnancy (28-32 weeks gestation).
