Table 9: Cohort studies on association between maternal 25(OH)D concentration and bone health indices in the offspring Author/Year Population Design Mean maternal 25(OH)D concentration (nmol/L) Mean cord 25(OH)D concentration (nmol/L) Findings Mahon et al (2010) Southampton, UK Pregnant women (n=424) Mean age: 31.3 (3.6)y Longitudinal At 34 wks: Median: 31.3 (IQR: 41-85) 5.9% < 25 30.7% < 50 Not measured Infants born to mothers with 25(OH)D concentration < 50 nmol/L had increased femoral splaying indices compared with > 50 nmol/L. Prentice et al (2009) The Gambia, Africa Pregnant women (n=125) and their infants Mean age: 27.4 (7.5)y Original Ca RCT. Cross-sectional with longitudinal follow up At 20 wks: 103 (25) At 36 wks: 111 (27) Not measured No relationship between maternal 25(OH)D concentrations and BMC/BMD of radius and whole body in infants. Viljakainen et al (2010) Helsinki, Finland Pregnant women (n=125) Mean age:31 (4) y Cross-sectional and longitudinal 1 st trimester: 41 (13.6) Postpartum: 45.1 (11.9) 50.7 (14.9) Median 25(OH)D concentration (42.6 nmol/L) used as cut off. Tibia BMC of infants born to mothers above the median was 0.047g/cm higher than those born to below median group but there was no difference in BMD. Young et al (2012) Baltimore, USA 171 Pregnant adolescent girls (n=171) and their infants Longitudinal follow up 26 weeks gestation and at delivery: 54.7 (27.5) Not measured. Maternal 25(OH)D > 50 nmol/L significantly positively associated with fetal femur and humerus z scores. (p < 0.01). Age:
