Season of conception and risk of hypertensive disorder during pregnancy.

ABSTRACT:

Background

Hypertensive Disorder during Pregnancy (HDP) is the most prevalent obstetric conditions in maternal health, but the etiology of most cases remains unexplained. Seasonal variations in the conception of HDP may offer insights into the potential seasonal-specific risk factors.

Methods

Data were sourced from the China's National Maternal Near Miss Surveillance System (NMNMSS) between January 1, 2012, and December 31, 2021. HDP status was ascertained from the diagnostic records over 400 medical institutions. The conception date was estimated based on the delivery date and duration of gestation length, and the season of conception, were categorised as winter (December to February), spring (March to May), summer (June to August), and fall (September to November).
