Pica in pregnancy in a privileged population: myth or reality.Acta Obstet Gynecol Scand. 2006; 85(10):1265-6.AO
In the literature pica is reported to be prevalent in pregnant women. Most studies have focused on less privileged populations, but is pica prevalent among privileged pregnant women?
100,000 pregnant women in the Danish National Birth Cohort were asked about pica in a food frequency questionnaire mailed in gestation week 25.
The response rate of the questionnaire was 70% of Danish National Birth Cohort participants. Only 14 women reported to have eaten substances that were clearly not foods, i.e. 0.02% had pica in this cohort of well nourished Danish women.
It seems that, in privileged populations, pica is more a myth than a reality.
