Background. Obesity has become an epidemic and an important public health concern. This study is the first longitudinal study to assess whether the weight status of adults with intellectual disabilities (ID) has an impact on depression.

Methods. This study analyzed a subset of the three-year Longitudinal Health and Intellectual Disability Study data (N= 967). The outcome was a diagnosis of depression. We employed a generalized estimating equation (GEE) model adjusting for characteristics (age, gender), life style factors (smoking, alcohol drinking, physical activity), and psychosocial factors (general health status, life events, social participation).

Results.  At baseline, 33% of adults (≥ 18 years) with ID were obese (BMI ≥ 30 kg/m2); 15% were depressed. There are no significant differences in the obesity and depression rates across three years. Results of the GEE model indicate that obesity has a positive impact (B = 0.03, 95% CI = 0.92 - 0.57) on depression after adjusting for characteristics, life style factors, and psychological factors.  The significant adjusting variables included being female (B = 0.33, 95% CI = 0.92 - 0.59), age (B = 0.17, 95% CI = 0.07 - 0.27), health status (B = 0.30, 95% CI= 0.18 - 0.43), and life events (B = 0.32, 95% CI = 0.11 - 0.53).

Conclusion.  There is a need to further explore effective mental health promotion programs tailored toward coping skills and promoting healthy lifestyles to lower obesity in adults with ID.  A clearer understanding of mechanisms explaining the relationship between depression and obesity is also needed.

Learning Areas:

Public health or related research
Social and behavioral sciences

Learning Objectives:
Evaluate the relationship between obesity and depression in the general population. List at least three associated factors of obesity that need to be adjusted for adults with intellectual disabilities when examining the impact of obesity on depression. Discuss the implication of the findings and future research directions.
