Title: Association Between Dietary Phosphorus Intake and Chronic Constipation in Adults:
Evidence from the National Health and Nutrition Examination Survey
Version: 4 Date: 09 Aug 2022
Reviewer's report:
This study examined the association between dietary phosphorus intake and chronic constipation
using NHANES data in the U.S. The relationship of micronutrient intake with intestinal health
has been reported continuously and this work will be of interest to the readers. However, there
are several issues to be improved.
1. Research implications of the study results and suggestions need to be stated more clearly.
There were two diagnostic criteria for chronic constipation used in this study, but evaluation
results of the two did not have the same findings in relation to phosphorus intake.
2. Participant Selection – the reasons for exclusion of participants with phosphorus intake greater
than 4000mg need to be addressed. This sentence seems confusing “… excluded 237 people
with dietary phosphorous deficiency…” Needs rewrite.
3. Did the authors perform an analysis of water and beverage intake? If not, explanations for
this need to be provided.
