Key result
Highest dietary niacin intake is linked to ~45% lower odds of COPD versus lowest intake.
Why the study?
Evidence regarding the association between dietary niacin intake and chronic obstructive pulmonary disease is limited.
Does higher dietary niacin intake reduce the prevalence of COPD in US adults?
Cross-Sectional (n=7,055)
Yes
Does higher dietary niacin intake reduce the prevalence of COPD in US adults?
Odds Ratio: 0.55 (95% CI 0.33–0.89)
p-value: p=0.009
Higher dietary niacin intake is independently associated with a lower prevalence of COPD in US adults, suggesting a potential protective effect that warrants further investigation.

Hypothesis-generating for niacin in COPD; prospective trials needed before any practice change.
Li et al. (2024) conducted a cross-sectional in Chronic obstructive pulmonary disease (COPD) (n=7,055). Dietary niacin intake vs. Lowest quartile of dietary niacin intake was evaluated on Prevalence of COPD (OR 0.55, 95% CI 0.33-0.89, p=0.009). Participants in the highest quartile of dietary niacin intake had significantly lower odds of COPD compared to those in the lowest quartile (OR 0.55).
