Associations of gestational weight gain with offspring diastolic blood pressure, non-stratified and stratified by mother’s early-pregnancy body mass index, using fixed effects regression model.

Abbreviations: CI, confidence interval; BMI, body mass index. a Model 1 was adjusted for maternal age at birth, birth year and gestational age. Model 2 was adjusted as for model 1 plus early-pregnancy BMI, maternal education and parity. Model 3 was adjusted as for model 2 plus offspring’s age of conscription and conscription center. b Difference in offspring SBP in mmHg per 1-kg difference in gestational weight gain. c Difference in offspring SBP in mmHg per 1-kg greater gestational weight gain. d P-value to test whether the within and between effects differ, obtained by a Wald test.
