Authors' conclusion

Minimizing PPWR was linked to reduced mortality risk over 50 years of follow-up.

Study context

Population
Women with ≥ 2 pregnancies in the Collaborative Perinatal Project (CPP), U.S., 1959–1966, with vital status follow-up through 2016
Participants
8,165 women
Comparison
Quintiles of interconception weight change (ICWC) and interpregnancy weight change (IPWC)
Primary endpoint
All-cause mortality
Follow-up
Through 2016

All-cause and cause-specific mortality by IPWC quintile

Lower IPWC quintiles (greater weight loss) suggestive of reduced all-cause and cause-specific mortality risk; not statistically significant
