• To lay the groundwork for future analyses and studies on preterm birth.
• To provide essential data for improving maternal and perinatal health outcomes.

Main Methods:

• A multicenter cross-sectional study design was employed.
• A nested case-control study was incorporated to identify associated factors.
• Nationwide implementation involved detailed planning and problem-solving strategies.

Main Results:

• Twenty referral hospitals across Brazil participated in the study.
• Data collection involved a detailed questionnaire and an electronic monitoring platform.
• Information was gathered on 4,150 preterm births and 1,146 term births.

Conclusions:
