Factors associated with ex-nuptial birth.

Area of Science:

• Sociology
• Public Health
• Developmental Psychology

Background:

• Examines the social and personal factors surrounding 210 live exnuptial births.
• Focuses on the initial phase of the Christchurch Child Development Study.
• Investigates pregnancy planning and maternal attitudes in non-marital births.

Purpose of the Study:

• To understand the background of exnuptial births.
• To analyze the circumstances of conception and maternal experiences.
• To assess contraceptive knowledge and usage patterns.

Main Methods:

• Analysis of data from 210 live exnuptial births.
• Study of maternal situations and reactions to pregnancy and birth.
• Examination of contraceptive usage and failure rates.

Main Results:

• Approximately 50% of children were conceived within cohabiting unions.
• About 20% of exnuptial pregnancies were planned.
• Cohabiting mothers reported fewer adverse reactions compared to non-cohabiting mothers.
• Mothers demonstrated good contraceptive knowledge, but 25% of unplanned pregnancies resulted from method failure, and 75% from non-usage.
• 35% of unplanned pregnancies were linked to inconsistent oral contraceptive pill use.

Conclusions:

• Cohabitation is a significant factor in exnuptial births.
• Maternal circumstances influence birth experiences.
• Contraceptive non-usage and inconsistent use are key contributors to unplanned exnuptial pregnancies.
