  1. HIV/AIDS in Puerto Rican Patients 50 Years or Older Alejandro Amill, MPH; María Gómez, Ph.D.; Doris Báez, MSc; Miriam Velásquez, MSc; Diana M Fernandez, MSc; Eddy Ríos, Ph.D., MPH; and Robert F. Hunter, MD, FACP. Universidad Central del Caribe, Bayamón, Puerto Rico Retrovirus Research Center

  2. Background • 11% (86,875) of the AIDS cases reported in the United States and 12% (3513) of the cases in Puerto Rico are from individuals 50 years or older. (CDC, 2002 & PR Health Department, 2003) • Elders are usually perceived as not being at risk for HIV infection and usually excluded from targeted prevention programs. (Chiao, Ries & Sande, 1999) • Health care providers are slow to diagnose HIV in older people. (Kasper & Cavalieri, 1999)

  3. Objectives • To characterize and describe HIV/AIDS infected patients 50 years or older of age in terms of their socio-demographic, risk and clinical profile , and compare them with a younger sample counterpart.

  4. Research Design • Prospective cohorts (IRB approved): HIV Central Registry (HCR), Adult Spectrum of Disease (ASD). • Data collection started on May 1992. • Setting: Hospital Universitario Ramón Ruiz Arnau and Immunology Clinic. • Data sources: Interview, medical records abstraction and laboratory blood samples. • Participants: Age ≥ 18 years, HIV/AIDS.

  5. Research Design Puerto Rico’s Health Regions. Source: Department of Health in Puerto Rico.

  6. Methods • Study design: Cross-sectional study from a longitudinal cohort. Data from 3151 study participants was collected between May 1992 and December 2002. • Study Sample: 288 (9.1% of the total study population) HIV/AIDS with age ≥ 50 years. • Bivariate analysis: Mantel-Haenszel Chi-Square (M-H X2) and Wilcoxon Rank Sum test . Significance level set at p< 0.05. • Variables were evaluated at year of patient enrollment. • Packages: SAS Windows V8, SPSS 11.0 Windows

  10. Results High school diploma or higher degree between the groups of age, n=2802 Age distribution by categories, n=288. ^ OR=0.489 C.I. (0.357, 0.671) P value < 0.0001 Median= 54 years

  12. Results Aids diagnosis at study entry, N=3151. ^ OR=1.48, C.I. (1.15, 1.89), p= 0.0017

  13. Results Type of Aids diagnosis at study entry, n=1582. ^ OR=0.694, C.I. (0.423, 0.965), p= 0.048

  16. Results Table 6. Immunology markers in patients with AIDS diagnosis.

  17. Results Survival function for patients with AIDS diagnosis at last follow up, n= 2168. Median of survival:18-49 (2.16 years), >=50 (1.85 years) P >0.05

  18. Conclusions • Elderly patients are less likely to have completed a high school education that their younger counterparts. • Elderly adults are more likely to exposed to heterosexual contact, specifically with a person with AIDS or HIV infection documented. • Elderly patients are seeking health care with a later stage of the disease and with several co-morbid chronic conditions.

  19. Limitations and Recommendations • Non probabilistic sample of all 50 years or older patients with HIV/AIDS in Puerto Rico. • More research from population base prospective data is needed in order to generate models for risky behaviors prediction and clinical outcomes. • HIV/AIDS health interventions and programs for prevention base on this data could result in reduction of risk exposures and morbidity outcomes among elders in Puerto Rico.
