Title:Rumination syndrome in children and adolescents: a school survey
assessing prevalence and symptomatology
Version: 2Date:5 July 2012
Reviewer: Kathleen Blondeau
Reviewer's report:
The authors studied the prevalence of rumination syndrome in a group of
otherwise healthy children and adolescents in Sri Lanka. They conclude that the
overall prevalence of RS is 5.1%, with an impact on sleep and school in less than
15% of children.
Major Compulsory Revisions
The authors state that they investigated the prevalence of RS in otherwise
healthy children. Which other disease were excluded? Can this be better
specified.
As statistics are an important part of the data analysis, the authors may need to
better describe in the methods section the statistical test they used for
comparison of the different parameters as this is unclear.
The specific questionnaires used in the study should be better clarified in the
methods section, including if the Rome III questionnaire is appropriate for
children and which questionnaires where used to assess stress factors etc….
Minor essential Revisions
On p3 the authors state that there is no statistical significance (p<0.05). I assume
this is an error
Did the authors assess the frequency of rumination episodes and was there any
association with other factors such as sex, stress, weight loss,…..
Discretionary Revisions
Are there any population data in a dults and how does this compare to the
pediatric population?
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Needs some language corrections before being
published
Statistical review: Yes, but I do not feel adequately qualified to assess the
statistics.
