Background and Aims Alcohol consumption is common in adolescence and young adulthood and may continue into pregnancy, posing serious risk to early fetal development. We examine the frequency of periconception alcohol use (prior to pregnancy awareness) and the extent to which adolescent and young adult alcohol use prospectively predict periconception use. Design A longitudinal, population‐based study. Setting Victoria, Australia. Participants A total of 289 women in trimester three of pregnancy (age 29–35 years; 388 pregnancies). Measures The main exposures were binge [≥ 4.0 standard drinks (SDs)/day] and frequent (≥ 3 days/week) drinking in adolescence (mean age = 14.9–17.4 years) and young adulthood (mean age 20.7–29.1 years). Outcomes were frequency (≥ 3 days/week, ≥ monthly, never) and quantity (≥ 4.0 SDs, ≥ 0.5 and
