16 Poly-pathology is more common with increasing age and HIV Poly-pathology prevalence in cases and controls, stratified by age categories. The following co-morbidities were analysed: Hypertension, Type Diabetes, Cardiovascular Disease and Osteoporosis. Poly-pathology prevalence was higher in cases than controls in all age strata (all p-values <.1). Poly-pathology prevalence in cases aged 41-5 was similar to that in controls aged >6 (p=.8).

26 Summary The HIV infected population is ageing HIV may affect the natural ageing process Co-morbidities are increasingly apparent ART needs to be chosen not only for providing long-term efficacy but also for having the lowest impact on ageing comorbidities
