Objective: To enumerate pregnancy outcomes for a representative sample of women in Australia surveyed in 2012-2013 (primary aim) and compare these with women surveyed in 2001-2002 (secondary aim).
Methods: Computer-assisted telephone interviews with over 10,000 women aged 16-69 years (participation rate 68.4%). Results are weighted for chance of selection and to reflect the population as a whole.
Results: Of women with experience of vaginal intercourse, 75.1% had ever been pregnant, 18.4% reported difficulties getting pregnant and 10.0% had had fertility treatment. Of those who had been pregnant, 91.3% had ever had a live birth, 34.3% a miscarriage, 22.8% an abortion and 2.3% a stillbirth; 0.9% had relinquished a child for adoption. The proportion first pregnant in their 30s was 11% among women aged 60-69 and 26% among those aged 40-49. Fewer older women reported difficulties getting pregnant. Of the 21,882 pregnancies reported, 70% led to live births and 10% were terminated. Compared with our 2001-2002 survey, fewer women reported ever having been pregnant. Giving up newborns for adoption has become very rare.
Conclusions: Falling fertility since the 1960s reflects greater access to contraception and abortion and higher opportunity costs of childbearing. Implications for public health: These findings on women's lifetime reproductive experiences complement routine annual data collections.
