    Summary

    This study analyzed 3320 births in China to understand maternal age effects on reproductive outcomes. Findings reveal correlations between maternal factors and perinatal death, prematurity, and birth weight.

    Area of Science:

    • Obstetrics and Gynecology
    • Perinatal Medicine
    • Public Health

    Background:

    • Maternal health and reproductive parameters significantly influence perinatal outcomes.
    • Understanding these relationships is crucial for improving infant survival rates.
    • Historical data from specific regions can offer valuable insights into demographic health trends.

    Purpose of the Study:

    • To examine reproductive parameters in a 1978 cohort of 3320 singleton births.
    • To investigate the associations between maternal age, pregnancy history, and perinatal outcomes.
    • To explore the impact of maternal conditions and delivery procedures on birth weight and prematurity.

    Main Methods:

    • Retrospective analysis of clinical birth records from Tientsin Medical College Hospitals.

  • Data collection included maternal age, parity, pregnancy history, maternal conditions, delivery methods, and infant birth weight.
  • Statistical analysis to determine relationships between variables.

    • Main Results:

    • Average maternal age at first and successive births was determined.
    • Significant correlations were observed between maternal age, parity, and perinatal death rates.
    • Birth weight and prematurity showed relationships with maternal age, prenatal conditions, and delivery interventions.

    Conclusions:

    • Maternal age and reproductive history are key determinants of perinatal outcomes.
    • Prenatal care and appropriate delivery management are vital for optimizing birth weight and reducing prematurity.
    • This study highlights the importance of demographic factors in perinatal health assessment.
