Abstract

We assessed risk groups for excessive infant crying using 10 published definitions, in 3179 children aged 1-6 months (response: 96.5%). Risk groups regarding parental employment, living area, lifestyle, and obstetric history varied by definition. This may explain the existence of conflicting evidence on the occurrence and cause of excessive crying.
