Cross-sectional study compares brain volumes among sedentary normal weight, overweight, and obese adults, revealing unexpected BMI correlations.
Key Points
No significant differences in overall or regional brain volumes were found among weight groups, indicating complexity in brain structure's response to obesity.
In sedentary normal weight adults, BMI positively correlated with right superior temporal gyrus volume, highlighting the potential of brain volume metrics in understanding weight impacts.
In the obese group, BMI exhibited a negative correlation with right superior temporal gyrus volume, suggesting that obesity may influence specific brain structures differently.
The findings underscore the need to explore the neurological effects of obesity on brain structure in sedentary populations, given the contrasting correlations observed.
