Association of maternal BMI with vitamin B12 and folate concentrations (tertiles).
<p>Bars represent geometric mean BMI for each group.</p
Univariate associations between B12, folate and BMI with potential confounders (lifestyle/demographic, pregnancy related and haemodilutional factors) in 995 pregnant women.
<p>* denotes log transformed data</p><p>Pearson correlation coefficients (r) presented for continuous variables</p
Multiple regression analysis to demonstrate the relationships between BMI and potential confounding variables on serum vitamin B12.
<p>*Denotes variable transformed using natural logs (allowing β coefficients to be interpreted in terms of percentage change)</p><p>Partial R is the adjusted correlation coefficient.</p
Baseline characteristics of study cohort (n = 995) at 28 weeks gestation.
