Brief Summary
Despite efficient antiretroviral treatment for HIV infection, decrease in life expectancy remains. Excess mortality is mainly due to non-AIDS co-morbidity including cardiovascular, pulmonary, and liver related diseases. Both HIV-unrelated and HIV-related risk factors probably contribute to this pattern. At present, most evidence regarding co-morbidity in HIV infection rely on cross-study comparisons of HIV-infected persons with published population rates and few prospective studies in U.S. cohorts. Using well characterized participants from the Copenhagen General Population Study (CGPS) as controls, we aim to include \>1500 HIV-infected persons in the COCOMO study to determine if co-morbidity is more prevalent or develops at a higher rate in HIV-infected persons. The study will asses 1) cardiovascular, 2) pulmonary and 3) liver-related co-morbidity using uniformly collected data in the two cohorts. The investigators aim to study the relative impact of HIV-unrelated and HIV-related factors on development of co-morbidity.
