The trends and associated factors of preterm deliveries from 2001 to 2011 in Taiwan

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Epidemiology

Background:

• Global increase in preterm birth rates poses significant risks to infant health.
• Preterm infants face heightened risks of neurological, respiratory, and gastrointestinal complications.
• Understanding regional trends and contributing factors is crucial for effective public health strategies.

Purpose of the Study:

• To investigate trends in preterm birth in Taiwan from 2001 to 2011.
• To identify obstetric antecedents and risk factors associated with preterm delivery in Taiwan.

Main Methods:

• Utilized data from the Taiwan National Medical Birth Register database.
• Included all live births in Taiwan between 2001 and 2011 (N=2,334,532).
• Employed multiple logistic regression analysis to identify risk factors.

Main Results:

• The proportion of preterm deliveries in Taiwan increased by 11.1% (8.2% in 2001 to 9.1% in 2011).
• Identified risk factors: nulliparity, multiple births, maternal medical complications, maternal age (<20 or ≥40 years), and medical indication for early delivery.
• Nulliparous women <20 or ≥40 years old were particularly at risk.

Conclusions:

• Preterm birth rates show an increasing trend in Taiwan.
• Specific maternal characteristics and circumstances significantly elevate the risk of preterm delivery.
• Identifying and supporting high-risk groups, such as young or older nulliparous women, is essential for prevention efforts.
