'No thanks'-reasons why pregnant women declined an offer of cystic fibrosis carrier screening.

The objective of this study was to assess attitudes and opinions of women declining the offer of cystic fibrosis (CF) carrier screening through a population-based programme in Victoria, Australia. Between December 2009 and May 2011, women declining an offer of CF carrier screening were invited to participate in a questionnaire-based study. Recruitment was at two private obstetric ultrasound clinics and two private obstetric practices in Melbourne. Of the participants (n = 54), the majority were well educated (76%), aged 30-34 years (54%), with a household income of >AUD$100,000 (76%). Compared to those who accepted screening (reported in a previous study) (Ioannou et al., Public Health Genomics 13:449-56, 2010), knowledge levels were significantly lower in participants declining screening (t = 3.32, p < 0.01). The main reasons for declining screening were having no family history of CF (58%) and not considering a termination of pregnancy for CF (53%). Providers and consumers should be informed that most children born with autosomal-recessive conditions such as CF have no family history of the condition.
