Prevalence of anxiety disorder and its association with BMI: an analysis of women’s experiences in Bangladesh using BDHS-2022 data

This study identified a significant association between BMI and anxiety disorder, revealing a U-shaped relationship where both underweight and obesity were correlated with higher odds of anxiety disorder. Although the results indicate that maintaining a healthy BMI could be associated with a decrease in anxiety levels, the cross-sectional nature of the study prevents establishing a causal relationship. This implies that BMI and anxiety may be correlated, but one does not necessarily cause the other. Future longitudinal studies are needed to explore potential causal mechanisms. The observed association highlights the importance of considering body weight extremes in mental health interventions. These findings underscore the need for integrated public health strategies that address both mental health and nutritional well-being among ever-married women in Bangladesh.
