Key points An underweight body mass index (BMI) and substantial decrease in BMI >5% over 2 years in older age were associated with increased dementia risk, but these associations were attenuated over time, suggesting potential reverse causality. An overweight or obese BMI, as well as an elevated waist circumference (WC) in later life, were associated with lower dementia risk, but a two-year increase in BMI >5% showed an association with greater risk of dementia.

The findings – some of the most robust on this topic to date – may help older individuals and aged care professionals plan more targeted approaches to reducing dementia risk.
