Body mass index and clinical outcomes in patients after ischaemic stroke in South Korea: a retrospective cohort study.

ABSTRACT:

Objectives

Although obesity is a risk factor for stroke, its impact on mortality in patients with stroke remains unclear. In this study, we aimed to evaluate the relationship between body mass index (BMI) and mortality due to ischaemic stroke among adults aged 20 years and above in Korea.

Design

Retrospective cohort study.

Setting

A tertiary-hospital-based stroke registry linked to the death records.

Participants

3599 patients admitted for ischaemic stroke from January 2007 to June 2013.

Outcome measures

The HRs for all-cause and stroke-related mortality were calculated using Cox proportional hazards models. Progression from stroke-related mortality was assessed using the Fine-Grey competing risk model, treating other-cause mortality as a competing risk.
