Constipation associated with all-cause mortality among individuals with type 2 diabetes: Study
Constipation associated with all-cause mortality among individuals with type 2 diabetes suggests a new study published in the Journal of Diabetes Investigation.
Constipation is a common complication in type 2 diabetes mellitus (T2DM), yet its impact on mortality remains unclear. This study investigated the association between constipation and all-cause mortality in patients with type 2 diabetes mellitus.
They conducted a retrospective cohort study using data from the National Health and Nutrition Examination Survey (NHANES) 2005-2010. Mortality outcomes were ascertained through linkage to National Death Index records until December 31, 2019. The association between constipation and all-cause mortality was assessed using weighted Cox proportional hazards regression models. Kaplan-Meier curves were then employed to visualize survival probabilities.
Effect modification was explored through stratified analyses and interaction tests. Results: Of 1,339 participants with type 2 diabetes mellitus, 146 (10.90%) reported constipation. During a median follow-up of 10.75 years, 411 deaths occurred (57 in the constipation group, 354 in the non-constipatio
n group). Fully adjusted weighted Cox regression analysis revealed that constipation was associated with increased all-cause mortality (HR 1.50, 95% CI 1.01-2.22, P = 0.04). Kaplan-Meier analysis demonstrated a significantly lower survival probability in patients with constipation (log-rank P < 0.05). Stratified analyses and interaction tests corroborated these findings across various subgroups. Constipation is associated with elevated all-cause mortality risk in type 2 diabetes mellitus patients.
These findings suggest that constipation management may be an important consideration in improving long-term outcomes for individuals with type 2 diabetes mellitus.
