To investigate the association between body mass index (BMI) and the first-onset clinical diagnosis of specific mental disorders, including depression and anxiety, in a large cohort, while controlling for potential mediating factors such as cardiometabolic disorders.
Approach:
Key Findings:
Obesity and underweight were associated with an increased risk of first-onset mental disorders, with statistical significance noted.
The risk of mental illness varied by sex, age, and ethnicity.
Individuals with obesity had a higher prevalence of depression and anxiety compared to those with normal weight.
Interpretation:
The findings suggest that both obesity and underweight status may precede the diagnosis of mental disorders, highlighting the need for early intervention strategies targeting these populations to improve clinical outcomes.
Limitations:
The study relied on electronic health records, which may have incomplete data.
Potential confounding factors may not have been fully accounted for.
The observational nature of the study limits causal inferences.
Self-reported data may introduce biases.
Conclusion:
This large-scale cohort study underscores the importance of monitoring BMI as a potential risk factor for mental disorders, advocating for integrated approaches in mental health and obesity management, and calling for further research to explore these associations.
