The Claim
The association between obesity and slower cognitive decline is not significantly different between Black and White adults.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Obesity is associated with slower cognitive decline in both Black and White adults, and the strength of this association is the same across both groups.
See the scientific wording
The association between obesity and slower cognitive decline does not differ significantly between Black and White adults, indicating that racial disparities in cognitive decline are not explained by differences in obesity prevalence.
Excess body fat releases chemicals that trigger inflammation in the brain, which damages brain cells and lowers initial thinking skills, but also slows down how fast those skills get worse over time, and this pattern happens the same way in both Black and White adults.
What the research says
1 studyStudy: Association of Obesity With Cognitive Decline in Black and White Americans
This study found that being overweight or obese slows down memory loss at about the same rate for both Black and White adults, so differences in obesity rates between the groups can't explain why Black adults tend to lose memory faster overall.
