Background:
In human health, vitamins play a vital role in various metabolic and regulatory processes and in the proper functioning of cells. Currently, the effect of Vitamin E (VE) intake on multiple causes of death in Chronic obstructive pulmonary disease (COPD) patients is unclear. Therefore, this paper aims to investigate the relationship between VE and multiple causes of death in COPD patients, to guide the rationalization of dietary structure and reduce the risk of COPD death.
Methods:
This study screened patients with COPD aged ≥40 years from the National Health and Nutrition Examination Survey (NHANES) database 2008-2018. Weighted COX regression was used to analyze the association between VE intake and multiple causes of death in COPD. The restricted cubic spline(RCS) is drawn to show their relationship. Finally, we conducted a subgroup analysis for further verification.
Results:
A total of 1261 participants were included in this study. After adjustment for multiple covariates, VE intake was associated with all-cause death in COPD patients, and chronic lower respiratory disease (CLRD) deaths were linearly associated with cardiovascular disease (CVD) deaths there was no such correlation. Subgroup analyses showed no interaction between subgroups, further validating the robustness of the relationship.
Conclusion:
In COPD patients, VE intake was negatively associated with all-cause mortality and CLRD death. Higher VE intake reduces the risk of all-cause mortality and CLRD death in COPD patients.

Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.
