Abstract
Objective:
To examine the relationship between preconception blood pressure (BP) and the risk of preterm birth (PTB) using a historical cohort of reproductive-aged women and girls from a Chinese rural population.
Design:
A historical cohort study established between 2010 and 2013 in People’s Republic of China.
Setting:
Local family-planning service agencies and maternal–child care service centers.
Patient(s):
A total of 367,425 reproductive-aged women and girls who participated in the National Free Pre-pregnancy Checkups in 2010–2012 and subsequently had a live birth before October 2013.
Intervention(s):
None.
Main Outcome Measure(s):
Incidence rates of PTB in reproductive-aged women and girls across preconception BP levels.
Result(s):
Preterm births were defined as babies born alive at 28 to 37 weeks of pregnancy. Compared with the participants with a systolic BP of
Conclusion(s):
Our results indicated a strong linear and independent relationship between BP levels and the risk of PTB in Chinese reproductive-aged women and girls. Maternal hypertension before pregnancy can significantly increase the risk of PTB.
