Data are adjusted coefficients from linear regression analyses, using all exposures as continuous variables, except IUGR, which was included in the model as a dummy variable (0=no; 1=yes).
Information about maternal height not available for India.
Glucose and offspring birthweight not available for South Africa.
Additional adjustment for adult BMI and height.
Adjusted for individual's age when the outcome variables were measured, years of schooling completed by the mother (in India, by the father), and a measure of early childhood socioeconomic status.
