Number with complete data on all variables included in models | Age adjusted regression coefficient logged IMT/g offspring birth weight | Age and BMI adjusted regression coefficient logged IMT/kg offspring birth weight | Age, BMI, social class and smoking adjusted regression coefficient logged IMT/kg offspring birth weight | |
---|---|---|---|---|
BMI, body mass index (kg/m2); smoking categorised as never, ex, current; social class derived from longest held social class and classified according to registrar generals classification – I, II, III non-manual, III manual, IV, V. In all models robust standard errors were used to calculate 95% confidence intervals taking into account the clustering effect of each town. | ||||
