TOPLINE:
Increased dietary intake of vitamin B1 is associated with a lower prevalence of constipation, particularly among men and individuals without hypertension or diabetes.
METHODOLOGY:
Researchers conducted a cross-sectional study using National Health and Nutrition Examination Survey data from 2005-2010 involving 10,371 adults aged ≥ 20 years.
Participants provided information on fecal characteristics and bowel movement frequency, which was documented for 30 days prior to data collection.
Constipation was established by either frequency of bowel movements (fewer than three per week) or stool consistency (Bristol Stool Scale type 1 or 2).
Data on vitamin B1 intake were collected through 24-hour total nutritional intake recall interviews. Patients were divided into three groups based on their level of B1 intake: 0.064-1.21 mg, 1.21-1.76 mg, and 1.76-12.61 mg.
TAKEAWAY:
Overall, 10.8% of participants were identified as having constipation.
Higher vitamin B1 intake correlated with a decrease in constipation occurrence. Constipation prevalence was 7.69% in the group with the highest B1 intake, 10.7% in the middle group, and 14.09% in the group with the lowest intake (P < .001).
Greater dietary vitamin B1 intake was associated with a 23% reduction in constipation risk (P = .034).
Additionally, a subgroup analysis found that higher B1 intake was associated with a reduction in constipation risk of 20% in men, 16% in people without hypertension, and 14% in those without diabetes.
IN PRACTICE:
“This association suggests that enhanced intake of vitamin B1 through diet may facilitate softer stools and heightened intestinal motility, thereby potentially alleviating constipation symptoms. Consequently, healthcare professionals are advised to prioritize the promotion of a well-balanced diet as an initial therapeutic approach, preceding medical interventions,” the authors wrote.
SOURCE:
The study, led by Wenyi Du, the Affiliated Stomatological Hospital of Soochow University, Suzhou Stomatological Hospital, Suzhou, China, and Wuxi People’s Hospital Affiliated to Nanjing Medical University, Wuxi Medical Center, Wuxi, China, was published online in BMC Gastroenterology.
LIMITATIONS:
A causal relationship could not be established between vitamin B1 intake and constipation owing to the cross-sectional nature of the study. The study relied on patient interviews and patient self-reported data. Additionally, 24-hour dietary recalls may not have accurately reflected the long-term eating habits of the participants.
DISCLOSURES:
The study had no specific funding source. The authors declared no competing interests.
