Main Findings
In this study, we found different associations of gestational
stage-specific weight gain with venous thrombosis. Of those, higher GWG
in total or early pregnancy was associated with higher risks of PE in
normal-weight women. As for underweight and overweight women, results
from the categorical model for early or total pregnancy weight gain
indicated an increased risk at both low and high weight gain for PE, but
confidence intervals were wide.
