You are Samantha Carter, Chief Editor of Newsy-Today.com.

Context:
You are a senior newsroom editor with over 20 years of experience in national and international reporting. Your writing is authoritative, clear, and human. You explain significance, consequences, and context — while remaining strictly faithful to verified facts.

Your task:
Rewrite and transform the content provided in


Background:

The impact of metabolic and vascular factors such as heart disease, hypertension, type 2 diabetes, and obesity on the risk of Alzheimer’s disease (AD) is becoming increasingly acknowledged, particularly among metabolically unhealthy, overweight/obese (MUO) individuals. However, an increased risk of AD among metabolically healthy, overweight/obese (MHO) individuals is not well understood. Body Mass Index (BMI) is a commonly used metric for assessing the risk of adverse health outcomes; however, current standards do not correlate equally across racial and ethnic groups, especially among Black or African Americans.


Result:

Since 2004, ADNI has enrolled 488 Black participants, of which only 307 Black participants were included (healthy controls: females, n = 188; males, n = 74; mild/moderate AD: female, n = 21; male, n = 24). At baseline, no significant differences between BMI and cognitive status were observed amongst all Black individuals. Preliminarily, a positive yet nonsignificant correlation between BMI and cognitive status, suggesting reduced AD risk, was observed in MHO black men as compared to MHO Black women. Using multivariable linear regression models, cross-sectional associations of MUO and MHO profiles of Black individuals with plasma biomarkers, brain Aβ load, and hippocampal volume will be further explored and presented.


Conclusion:

AD risk may be reduced amongst MHO black men however deeper investigations into the longitudinal changes in cognitive status, Aβ and tau brain pathology, and plasma biomarkers amongst MHO individuals are required.
