1
Increase in the outcome variable by the Institute of Medicine guidelines; suboptimal (<11.5 kg), optimal (11.5-
16) and excessive (>16 kg) weight gain.
2
Adjusted for maternal pre-pregnancy BMI, age, parity, smoking status and educational level, offspring´s sex
and whether offspring thinks their father is overweight.
3
Same covariates as in 2 but without offspring sex.
4
T-test with gestational weight gain entered as dichotomous variable.
3
Supplementary table S3. Associations of maternal gestational weight gain during the
first 30 weeks of gestation with offspring cardio-metabolic risk factors at follow up adjusted additionally for offspring smoking, alcohol consumption and BMI at follow up
(n=308).
