Model 1 restricted to those with 2 conditions* Adjusted for baseline age, gender, race and education |
Model 1 restricted to those with 3+ conditions* Adjusted for baseline age, gender, race and education |

Note: All beta coefficients account for the complex sampling procedures of the HRS, and are weighted to make results nationally representative. The design-based degrees of freedom ranged from 33–56. Bolded p-values are statistically significant.
Corresponds to the sum of health conditions for each participant at each wave. Health conditions include: heart condition, stroke, high blood pressure, pain, arthritis, cancer, diabetes, incontinence, and memory problem.
All results correspond to beta coefficient estimates of the change in the insomnia score across the years within each racial/ethnic group from linear regressions.
Estimates for analyses stratified by race/ethnic groups do not adjust for race/ethnicity.
