Body mass index and causes of death in chronic kidney disease.

ABSTRACT: In chronic kidney disease (CKD), a higher body mass index (BMI) is associated with a lower risk for death, but cause-specific death details are unknown across the BMI range. To define this, we studied 54,506 patients with CKD (stage 3 CKD- [91.5%]) from an institutional electronic medical record based-registry. We examined the associations among various causes of death (cardiovascular-, malignancy- and noncardiovascular/nonmalignancy-related deaths) across the BMI range using Cox proportional hazards and competing risks regression models. During a median follow-up of 3.7 years, 14,518 patients died. In the multivariable model, an inverted J-shaped association was noted between BMI and cardiovascular-related, malignancy-related, and noncardiovascular/nonmalignancy-related deaths. Similar as
