1
Overview
• Numerous studies linking obesity to increased risk of disability and receipt of SSDI (Burkhauser and Cawley, 2005; Lakdawalla, Bhattacharya, and Goldman, 2004; Ferraro et al., 2002; Narbro et al., 1996)
• Currently, we have a limited understanding of how being obese interacts with the disability application process – Not a listed impairment since October 1999
2
Contribution
• Research purpose is to examine rates of obesity amongst SSDI and SSI applicants, as well as the role of obesity in disability determinations
• Use SSA administrative (EDCS) data to examine:
– Trends in applicant obesity relative to population
– Level of SSA review required by BMI category
– Initial determinations and allowances by BMI category
• Data include self-reported weight and height at time of application
3
Summary of Findings
• Obesity prevalence amongst applicants has increased along with prevalence in general working-age population
• Obesity more prevalent amongst disability applicants – Partially driven by demographic (age, gender, education)
differences
– Not race?
• Musculoskeletal determination increases with BMI
• Greater prevalence of obesity among applicants at higher levels of review

Obesity and Disability Application
• Fundamentally, we are interested in causal relationships for shaping public policy responses
• Relationship between obesity and disability complex (potentially endogenous)
• Also complexity (ambiguity) in how obesity interacts with disability application, determination, and application review
7
Obesity and Disability Application
• Factors driving relationship between obesity and disability:
• At the individual level:
– Disability (illness) can result in weight gain or loss – Certain demographic groups more prone to obesity and
over-represented in disability applications – May face discrimination or a wage penalty for obesity
• At the macro level:
– Obesity more prevalent in south and mid-west – Areas of high unemployment

Further Analysis
• NHANES data are particularly well-suited to analyzing the effect of obesity on disability application – Contain detailed health information (potentially prior to
disability onset or at least application) – Have multiple measures of adiposity including percent body fat
(BIA) and measured weight and height – Contain a reasonable set of demographic characteristics – Multiple waves linked to SSA MBR, SSR, PHUS, and 831 files
• Burkhauser, Cawley, and Schmeiser (2008) – Alternative measures of adiposity better predict SSDI application
(although self-reported BMI performs reasonably well) – Adiposity mainly predictive of application for whites
11
Policy Implications
• Obesity leveling off, but at a high prevalence
– Child obesity also leveling off
• If obesity increases probability of SSDI or SSI application, or makes SSA’s determination process more difficult then the ongoing high prevalence will continue to be a burden on SSA
12
Policy Implications
• From a policy perspective, I’m most interested in the implications for how SSA handles obese disability applicants – Whether or not obesity increases disability or
disability applications, beyond SSA’s control – Plenty of public health and economic reasons to
reduce obesity in general population
• Does SSA require clearer guidelines for assessing whether obese applicants are disabled? Implications for obese recipient employment? Something else? 13
Conclusion
• Area of inquiry is important given the prevalence of obesity amongst disability applicants
• Curious to see the implications of subsequent research for informing SSA’s response to increased prevalence of obesity
