Age at obesity and association with subsequent dementia: Record linkage study

Journal article

Results The risk ratio for dementia in people admitted to hospital with obesity aged 30–39 years was significantly increased at 3.5 (95% CI 2.1 to 5.6). Risk ratios for dementia then gradually reduced with increasing age at obesity from 1.7 (95% CI 1.3 to 2.2) in people aged 40–49 years when obesity was first recorded to 1.4 (95% CI 1.3 to 1.5) in those aged 60– 69 years. People in their 70s when obesity was recorded had neither an increased nor a reduced risk of subsequent dementia at 0.97 (95% CI 0.93 to 1.01), and those aged ≥80 years had a reduced risk of subsequent dementia at 0.78 (95% CI 0.74 to 0.82).
