Advances in research of multimorbidity among HIV-positive individuals

Multimorbidity is the co‑existing of two or more chronic diseases or health problems. Widespread access to antiretroviral therapy has led to a marked improvement in the immune status and life expectancy among HIV-positive individuals. HIV-positive individuals suffer from higher burden of chronic non-communicable diseases and are more likely to show a premature aging and frailty trend compared with the general population. The consequent increase in the prevalence of multimorbidity leads to the increasing in medical and economic burden， and different comorbidity patterns may indicate different risk factors and have different effects on health outcomes， posing challenges to healthcare and comprehensive management for HIV-positive individuals. This review summarizes research advances in prevalence， associated factors and patterns of comorbidities among HIV-positive individuals.
