Objective

The use of a pacifier has been reported to be a causative factor of recurrent acute otitis media (RAOM) because the negative pressure which is generated during sucking may cause a negative intra-tympanic pressure and favour the reflux of nasopharyngeal secretions into the Eustachian tube. Push and pull (P&P) plastic bottle caps, recently marketed in Italy, might also induce negative nasopharyngeal pressure.

This study was aimed to investigate if there is a difference in the prevalence of habitual use of P&P plastic bottle caps among children with a positive history of RAOM and healthy controls.

Methods

A telephonic interview was performed in order to retrospectively evaluate the prevalence of habitual use of P&P plastic bottle cap among children with a history of RAOM and healthy controls, comparable to the former for environmental risk factors for RAOM.

Results

Data were obtained from 57 Caucasian patients (males = 36/57; 63.2 % ) with a median age of 59 (range = 21-90) months, including 28 children with a history of RAOM and 29 healthy controls. Habitual use of P&P plastic bottle cap was significantly (p = 0.047) more frequent in children with a history of RAOM (14/28; 50.0 % ) than in control group (7/29; 24.2 % ). Multivariate logistic regression analysis adjusted for age confirmed a significant association (p < 0.01; Pseudo R² = 0.2) between the use of P&P plastic bottle cap and a positive history of RAOM (adjusted OR = 4.0; range = 1.1-15.0).

Conclusions

Our preliminary data show a significantly increased prevalence of P&P plastic cap bottle habitual users among children with a history or RAOM and support the need for larger studies to confirm the role of using P&P bottles as risk factor of RAOM and to identify the age groups at higher risk.
