Trends in contraception and sterilization in Australia

Area of Science:

• Reproductive Health
• Demographic Trends
• Contraceptive Practices

Background:

• Contraceptive use and sterilization patterns in Australia have evolved significantly.
• Understanding these trends is crucial for public health planning and reproductive services.

Purpose of the Study:

• To provide the first national estimates of trends in contraception and sterilization in Australia over 30 years.
• To analyze shifts in method choice and demographic correlations.

Main Methods:

• Utilized life-history data from a 1986 national survey of Australian women.
• Analyzed trends from the early 1960s to 1986.

Main Results:

• The oral contraceptive pill became the dominant method post-1961.
• Sterilization increased significantly from the early 1970s, particularly for women aged 35+.
• Contraceptive use patterns for married and unmarried women are now similar.
• Childless married women are more likely to use reversible contraception than those with children.

Conclusions:

• Significant shifts in contraceptive and sterilization trends have occurred in Australia.
• Sterilization has become a primary method for older women.
• Demographic factors like marital status and parity influence method choice.
