Authors' conclusion

Lower genetic risk and higher first-trimester CVH were independently and additively associated with lower risk of developing HDPs in nulliparous individuals.

Study context

Population
Genotyped nulliparous individuals with singleton pregnancies, nuMoM2b cohort, 8 US sites, 2010–2013mean age 27.0 years
Participants
7,499 individuals
Exposure
High vs low genetic risk and low vs high first-trimester cardiovascular health (CVH)
Outcome
Development of HDP (preeclampsia/eclampsia or gestational hypertension)

Main finding

As reported in the abstract

HDP
Adjusted odds ratio (95% CI)P value
High genetic risk vs Low genetic risk
2.21(1.78–2.77)
P < 0.001
Low CVH vs High CVH
2.92(2.28–3.74)
P < 0.001
Participants developing HDP overall
1,032 (13.8%)
HDP incidence, low genetic risk + high CVH
4.5%
HDP incidence, high genetic risk + low CVH
25.7%
High vs low CVH: lower HDP risk across genetic risk strata
53%-74%
No significant interaction between genetic risk and CVH
P for interaction > 0.05

Observational data: associations, not effects.

Findings consistent for preeclampsia/eclampsia and gestational hypertension separately
