Changes in Behavior with Increasing Pregnancy Attempt Time: A Prospective Cohort Study.

ABSTRACT:

Background

The extent to which couples change their behaviors with increasing pregnancy attempt time is not well documented.

Methods

We examined change in selected behaviors over pregnancy attempt time in a North American preconception cohort study. Eligible females were ages 21-45 years and not using fertility treatment.

Results

Among 3,339 females attempting pregnancy for 0-1 cycles at enrollment, 250 contributed 12 months of follow-up without conceiving. Comparing behaviors at 12 months versus baseline, weighted for loss-to-follow-up, we observed small-to-moderate reductions in mean caffeine intake (-19.5 mg/day, CI = -32.7, -6.37), alcohol intake (-0.85 d
