To help clinicians better assess and treat functional disabilities in
persons with acquired immunodeficiency syndrome (AIDS), the authors
estimate empirical relations among biologic and physiologic variables,
symptoms, and physical functioning in persons with AIDS. The sample of
305 persons with AIDS for this cross-sectional analysis came from three
sites in Boston, Massachusetts: a hospital-based group practice, a human
immunodeficiency virus clinic at a city hospital, and a staff-model
health maintenance organization. Physical functioning, 10 AIDS-specific
symptoms, and mental health were assessed by interview. Clinical
diagnoses, comorbidities, health habits such as smoking, laboratory
results, and selected medication use were assessed by chart review.
Significant predictors of physical functioning P < 0.01, R2 = .58) in a
multivariable regression model included energy/fatigue, neurologic
symptoms, fever symptoms, a lower hemoglobin level, and current
non-pneumonia bacterial infection. Ninety-six percent of the explained
variance in physical functioning was accounted for by three symptom
complexes: energy/fatigue, neurologic symptoms, and fever symptoms.
Significant predictors of energy/fatigue in multivariable models
included poorer mental health, lower white blood cell count, longer time
since diagnosis, and weight loss (P < 0.01, R2 =.36). Significant
predictors of neurologic symptoms included poorer mental health, weight
loss, and no zidovudine use (P < 0.001, R2 = .30). Predictors of fever
symptoms included poorer mental health, no zidovudine use, weight loss,
and history of asthma or chronic obstructive pulmonary disease (P <
0.05, R2 = .25). In conclusion, symptom reports were strong predictors
of physical functioning. Poorer mental health and weight loss were
correlated consistently with worse symptoms, and not using zidovudine
was correlated with worse neurologic and fever symptoms. These
variables, and the others the authors identified, may represent mutable
determinants of physical functioning in persons with AIDS, and potential
targets for specific clinical interventions.
