Vitamin D data

Table of Contents


These data come from a large cross-sectional observational study on vitamin D status in four European countries (Andersen et al., 2005). The data provide age, body mass index and vitamin D status for 420 women from 4 European countries. Vitamin D status is given via a measurement of 25-hydroxy-vitamin D (25OHD) in serum and among the questions to be addressed using these data is whether the 25OHD-level depends on BMI and on age.
