An additional25 women were excluded due to extreme energy intakes (the1% highest and 1% lowest intakes).Alcohol intakeOf the remaining 1264 women, 1153 (91%), 1135 (90%), 793(66%) and 377 (30%) completed the questions on alcoholintake before pregnancy, and during the 1st trimester, 2nd trimesterand 3rd trimester, respectively (table 1). Alcohol intakesbefore pregnancy and in the first trimester were significantlyhigher (p<0.0001) than in the 2nd and 3rd trimesters (11.2,4.0, 1.8 and 1.9 units/week, respectively). The prevalence ofwomen consuming more than 2 units per week was highestbefore pregnancy (74%) and in the 1st trimester (53%), withmean intakes for women reaching 15.1 units (95% CI 14.1 to16.1) and 7.2 units (95% CI 6.6 to 7.9) per week, respectively.The prevalence of “risky drinkers” was relatively low at 11%,2% and 3% for trimesters 1, 2 and 3, respectively, but much
