Prenatal Urban Environment and Blood Pressure Trajectories From Childhood to Early Adulthood

JACC AdvPublished Prospective birth cohort study

Authors' conclusion

Replicated findings suggest that higher prenatal humidity and temperature could modulate blood pressure changes across childhood.

Study context

Population
Participants of a UK birth cohort, with BP measured repeatedly from childhood to early adulthoodreplication up to 9,261
Participants
7,454 participants
Exposure
Prenatal urban environmental exposures and BP trajectories
Outcome
Trajectories of SBP and DBP (change over time)
Follow-up
Childhood to early adulthood
Methodological detailsexposome-wide association study, replication in 4 independent European cohorts, Linear spline mixed-effects models
  • Exposome-wide association study

Main finding

As reported in the abstract

SBP change in childhood (discovery)
Mean yearly change in SBP, mm Hg/y (95% CI)
Humidity (per IQR increase)faster increase
0.29(0.20–0.39)
Temperature (per IQR increase)slower increase
−0.17(−0.28 to −0.07)

Per IQR increase, as printed

Observational data: associations, not effects.

Further findings

Replication in other cohorts

Results for humidity and temperature replicated; air pollution not replicated
