Title: The association between dietary vitamin B1 intake and constipation: a population-based
study
Version: 1 Date: 16 Nov 2023
Reviewer's report:
Comments to the Author(s):
The authors examine the link between vitamin B1 intake and chronic constipation, which has
not been extensively explored in previous research. The focus of this study is interesting. The
use of a large, nationally representative sample from the NHANES enhances the significance of
the findings, potentially impacting public health guidelines and dietary recommendations.
I would like to comment on some of the questions that need clarification.
1. Limitations in Dietary Data Collection:
The reliance on 24-hour dietary records may not accurately reflect long-term dietary habits. This
could be one of the limitations of this study.
2. Lack of data on dietary fiber:
Several studies have shown a correlation between dietary fiber intake and vitamin B1 intake.
(doi: 10.1007/s001250051047.doi: 10.3390/nu14102078.)
Dietary fiber intake is inversely associated with constipation.
Dietary fiber may be a confounding factor in evaluating the association between vitamin B1
and constipation.
To explore the association between vitamin B1 consumption and chronic constipation, it is
advisable to conduct a multifactorial logistic regression analysis, incorporating supplementary
data regarding dietary fiber consumption.
