Title:Dietary intakes in people with irritable bowel syndrome
Version: 2Date:17 December 2010
Reviewer: Stine Störsrud
Reviewer's report:
The author(s) havre responded to most of the reviewers comments and I find the
article much better. The result part is much easier to read and to follow. Better
tables with p-values included!
However a few further comments:
1. IBS sufferers should be replaced by IBS subjects or IBS patients as many of
them really don´t suffer.
2. Abstract, Methods: you end the last line with "...between IBS subtypes and."
Something is missing.
3. Abstract, Results: ".....IBS sufferers met recommendations". Which
recommendations, specify! I also think you should point out that "intakes of
micronutrients exceeded the reference nutrient intake" - instead: statistically
exceeded
4. Inclusion of references on page 4: [6],[7]...[8],[9] and later on the same page
[8, 10-11] and [13-14]. You have to choose how to present, I prefere [6-7].
5. Discussion: During your disscussion you assume that IBS subjects avoid
certain foods and are therefor at risk of lower intake of energy and/or nutrients
and you write on line 1 and 2 in your discussion: The purpose of our study was to
assess.... and whether any alteration in dietary pattern...." What do you know
about whether or not the IBS patients had altered their dietary pattern. I think the
four last lines on page 13 ("Further analysis of the diet is needed to identify
whether specific food items ... are avoided") are very important and should be
included earlier in the discussion.
6. In the second part of the discussion you write about BMI, which differs
between the IBS subjects and the general population. Females with IBS have a
lower BMI, however higher intake of energy than the female gerneal population
with an energy intake of only 6,5 MJ. Could this be due to that female general
population underreport their intake, not only that female IBS underreport their
weight or have a higher energy expenditure?
7. You write on page 12 that "the FFQ used...tends to overestimate dietary
intakes...", however this is hard to believe according to the energy intake of the
female general population. Since the FFQ used in the studies is equivalent with
only minor modifications the overestimation of energy and maybe also fruit and
vegetables should be the same groups?
Level of interest: An article whose findings are important to those with closely
related research interests
Quality of written English: Acceptable
Statistical review: No, the manuscript does not need to be seen by a
statistician.
