Aim To match maternal dietary habits in pregnancy in 1991 and 2007, respectively, in a preliminary survey.
Methods Semi-quantitative food frequency questionnaires, designed according to Block (Am J Epidemiol 1986;124:453) related to the 6 previous months, distributed at delivery.
Statistics Student’s t test.
Results 100 questionnaires, 50 in 1991 and 50 in 2007, out of 600 per group, have been analysed and reported in the table.
