ObjectiveMistimed, unexpected or unwanted pregnancies occur in Australia, despite widespread contraception use. The objective was to estimate prevalence and ascertain modifiable social factors for prevention of unintended pregnancy.MethodsNational population-based survey of women and men aged 18-51 years recruited from a random sample of electors on the Australian Electoral Roll in 2013. Data were weighted to reduce non-response bias. Factors associated with unintended pregnancy were identified in multivariable analyses.ResultsData from 2,235 completed questionnaires were analysed (Women: 69%; Men: 31%). Of those ever pregnant or partner in pregnancy (59%), 40% had experienced an unintended pregnancy. Adjusting for other risks, ever having experienced sexual coercion (AOR, 95%CI=Women 1.948; 1.458-2.601; Men 1.657, 1.014-2.708); socioeconomic disadvantage (AOR, 95%CI=Women 1.808, 1.373, 2.381; Men 1.360, 1.004-1.841), living in a rural area (AOR, 95%CI=Women 1.403, 1.056-1.864; Men 1.583, 1.161-2.159), and for men being born overseas (AOR, 95%CI 1.989, 1.317-3.002) were significantly associated with unintended pregnancy.ConclusionsExperiences of sexual coercion, social disadvantage, rural residence and overseas birth are independently associated with unintended pregnancy in Australia.ImplicationsPublic health policy and health service initiatives should prioritise prevention of sexual coercion, reduction of social inequality and reduction of geographic inequality for those in rural areas.© 2015 Public Health Association of Australia.
