Why the study?
Does lower BMI predict poorer short-term and long-term outcomes in Japanese acute ischemic stroke patients?
Population
1,206 Japanese acute ischemic stroke patients (760 men; mean age 72.5 years).
Comparison
Underweight BMI category vs Normal weight BMI category
Design
Cohort
Key result
Being underweight (9.2% of patients) was associated with significantly higher rates of poor short-term and long-term outcomes after acute ischemic stroke compared to normal weight patients.

Does lower BMI predict poorer short-term and long-term outcomes in Japanese acute ischemic stroke patients?
Underweight BMI is associated with poorer short-term and long-term outcomes in Japanese patients with acute ischemic stroke compared to normal weight.
Kawase et al. (2016) conducted a cohort in Acute ischemic stroke (n=1,206). Underweight and obese body mass index (BMI) vs. Normal weight BMI was evaluated on Short-term outcome (modified Rankin scale ≥3) and long-term outcome (all-cause mortality). Being underweight (9.2% of patients) was associated with significantly higher rates of poor short-term and long-term outcomes after acute ischemic stroke compared to normal weight patients.
