Purpose: Sleep-disordered breathing (SDB) is not uncommon in children. The purposes of this study were to investigate the relationship between non-nutritive sucking (NNS) and the risk of SDB in children as well as assess the effect of infant feeding practices on SDB.
Methods: Eighty-four healthy four- to 12-year-old children were categorized either as high or low risk for SDB based on the Pediatric Sleep Questionnaire (PSQ). NNS and feeding practices were determined using a customized caregiver questionnaire.
Results: There was no statistically significant difference (P=0.21) between low- and high-risk children for a history of NNS. A statistically significant difference (P<0.001) was found for breastfed versus bottlefed children, with breastfeeding having a protective effect for SDB.
Conclusion: NNS had no effect on SDB, while breastfeeding reduced the risk substantially.
