Among older adults, the responsiveness of self-rated health to changes in Charlson comorbidity was moderated by age and baseline comorbidity

摘要: Abstract Objective To examine the impact of changes in comorbidity—as measured by Charlson comorbidity index—on self-rated health a large sample community-dwelling elderly over 1-year period, and to differential effects specific diagnostic categories. Study Design Setting Longitudinal survey data on were linked with Medicare inpatient, outpatient, physician visit for 30,535 U.S. residing Pennsylvania. Multivariate logistic regression fractional polynomials was used model relationships involving baseline changing decline, evaluate covariate interactions. Results Comorbidity change associated greater likelihood worsened health, but relationship nonlinear moderated age comorbidity. The appeared be less among older individuals those higher Declines most likely following new diagnoses metastatic tumors, paralysis, dementia. Conclusion Self-rated is responsive comorbidity, nonlinearity interactions suggest complexity how respond change. Younger initially low are more reduce self-ratings chronic conditions.
