This study examines pregnancy intention estimates according to question wording, by gender and other pregnancy characteristics. Data are drawn from a population-based survey in France in 2011 (5,272 women; 3,373 men). Participants randomly answered 1 of 2 questions on whether they had planned or wanted each of their pregnancies. We compare estimates of unplanned versus unwanted pregnancies for 11,612 pregnancies. The use of different wording yields a 6% point difference in estimates: 33.9% pregnancies were unplanned, 28.0% unwanted. Men were more likely to report unplanned pregnancies than women (OR=1.2 [1.0-1.4]). The odds of unplanned pregnancies were higher when started before 25 years (OR=3.0 [2.4-3.7]), among 4+ ranked pregnancies as compared to 1rst (OR=2.0 [1.5-2.6]) and significantly lower in 2nd pregnancies (OR=0.8 [0.7-0.9]). The same results pertained to unwanted pregnancies, with an additional year effect. This study reflects on the effect of survey instruments on national estimates of pregnancy intentions.
