Brief Summary in Lay Language

The reasons for the origin of a chronic inflammatory disease (IBD) are very varied and are often unsettled in particular cases.
In a new study from New Zealand it was proved, that thumb-sucking and nail-biting in the infancy leads for a reduction of the risk of e.g. asthma and hay fever. Nevertheless, a possible risk reduction for an IBD was not examined.
It is sure: both behaviour patterns raise the biodiversity of bacteria of the flora of the mouth. Hence, it seems possible, that thumb-sucking and
nail-biting raise also the variety of the childish intestinal flora and thereby decrease the risk for the origin of an IBD.

Brief Summary in Scientific Language

Thumb-sucking and nail-biting raise the proof likelyhood from enterobacteriaceae and intestinal parasite in the mouth. Hence, it seems possible that thumb-sucking and nail-biting also raise the variety of childish intestinal microbiome. Topically it was proved first that thumb-sucking and nail-biting in the infancy leads to a reduction of the risk of an atopic sensitization at the adult's age (Lynch et Al.:Pediatrics in 2016).
Hence, it is interesting to examine first in a case control study, whether thumb-sucking
and nail-biting protect also against IBD.

Interventions/Observational Groups

  •   IBD patients < 40 years are questioned by a 4 page questionnaire about the hygienic conditions, thumb-suckings, nail-biting, breast-feeding etc. in the childhood to different times.
  •   Siblings of IBD patients without IBD are questioned by a questionnaire about the hygienic conditions, thumb-suckings, nail-biting, breast-feeding etc. in the childhood to different times.

Primary Outcome

Relation between thumb-sucking or nail-biting in the pre-school age and/or at the young adult's age and the reduction of IBD risk. The data are raised by a patient's questionnaire.

Secondary Outcome

Relation between hygiene-related risk factors of IBD (use of disinfectants, animal contact, breast-feeding) and the reduction of IBD risk. The data are raised by a patient's questionnaire.
