Estimated odds ratios of obesity among U.S. adults, 1999–2012.
| Disability domain | Overweight and obesity combined (BMI ≥ 25 kg/m2) | Obesity (BMI ≥ 30 kg/m2) | Grade 2 and 3 obesity combined (BMI ≥ 35 kg/m2) | Grade 3 obesity (BMI ≥ 40 kg/m2) |
|---|---|---|---|---|
| Any disability | 1.24 (1.14, 1.36) | 1.32 (1.22, 1.44) | 1.49 (1.35, 1.64) | 1.55 (1.27, 1.89) |
| Activities of daily living (ADLs) | 1.15 (0.99, 1.33) | 1.26 (1.09, 1.45) | 1.51 (1.29, 1.78) | 1.59 (1.23, 2.06) |
| Instrumental activities of daily living (IADLs) | 1.11 (0.99, 1.25) | 1.21 (1.09, 1.35) | 1.43 (1.25, 1.65) | 1.43 (1.12, 1.82) |
| Leisure and social activities (LSAs) | 1.11 (0.98, 1.26) | 1.31 (1.16, 1.47) | 1.60 (1.37, 1.86) | 1.55 (1.22, 1.97) |
| Lower extremity mobility (LEM) | 1.38 (1.20, 1.59) | 1.54 (1.37, 1.73) | 1.86 (1.59, 2.19) | 1.85 (1.38, 2.49) |
| General physical activities (GPAs) | 1.28 (1.16, 1.40) | 1.36 (1.24, 1.48) | 1.54 (1.38, 1.71) | 1.61 (1.30, 1.99) |
Notes: Individual-level data (N = 30,363) from NHANES 1999–2012 waves. Logistic regressions were conducted to estimate the odds ratios of obesity among U.S. adults, adjusted by individual characteristics (gender, age, race/ethnicity, education, marital status, household income, smoking status, health insurance coverage, general health status, chronic conditions, and NHANES survey wave) and accounting for NHANES sampling design. 95% confidence intervals are in parentheses.
