Multimorbidity In Elderly Persons According To The Year Of Diagnosis Of Human Immunodeficiency Virus Infection: A Cross-Sectional Dat'Aids Cohort Study

Background. We assessed prevalence of multimorbidity (MM) according to year of human immunodeficiency virus (HIV) diagnosis in elderly people living with HIV (PLWH).Methods. This was a cross-sectional study of MM in PLWH aged >= 70 years from the Dat'AIDS French multicenter cohort. MM was defined as at least 3 coexistent morbidities of high blood pressure, diabetes mellitus, osteoporosis, non-AIDS cancer, chronic renal failure, cardiovascular and cerebrovascular disease, obesity, undernutrition, or hypercholesterolemia. Logistic regression models evaluated the association between MM and calendar periods of HIV diagnosis (1983-1996, 1997-2006, and 2007-2018). The secondary analysis evaluated MM as a continuous outcome, and a sensitivity analysis excluded PLWH with nadir CD4 count <200 cells/mu L.Results. Between January 2017 and September 2018, 2476 PLWH were included. Median age was 73 years, 75% were men, median CD4 count was 578 cells/mu L, and 94% had controlled viremia. MM prevalence was 71%. HBP and hypercholesterolemia were the most prevalent comorbidities. After adjustment for age, gender, smoking status, hepatitis C and hepatitis B virus coinfection, group of exposure, nadir CD4 count, CD4:CD8 ratio, and last CD4 level, calendar period of diagnosis was not associated with MM (P = .169). MM was associated with older age, CD4/CD8 ratio <0.8, and nadir CD4 count <200 cells/mu L. Similar results were found with secondary and sensitivity analyses.Conclusions. MM prevalence was high and increased with age, low CD4/CD8 ratio, and nadir CD4 count <200 cells/mu L but was not associated with calendar periods of HIV diagnosis. Known duration of HIV diagnosis does not seem to be a criterion for selecting elderly PLWH at risk of MM.
