Information sources:
Five electronic databases were systematically searched (MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Scopus, Embase, and International Pharmaceutical Abstracts (IPA)). The search strategy was based on Medical Subject Headings (MeSH) and free text keywords in each database. Search terms included: pregnancy prevent*, risk manag*, teratogen*, risk perception and perceive*. No limits were applied to publication dates. Papers not written in English and conference abstracts were excluded. Reference lists of included articles were manually screened to identify additional papers for inclusion in the review. The full search strategy is available in Appendix 1.
