Sex Differences in Metabolic Disorders of Aging and Obesity in People with HIV

As advances in antiretroviral therapy for people with HIV (PWH) have prolonged lifespans, prevalence of aging and obesity related metabolic disorders have increased. The purpose of this review is to summarize recent research assessing sex differences in metabolic disorders among PWH, including weight gain/obesity, steatotic liver disease, insulin resistance/diabetes, dyslipidemia, bone loss/osteoporosis, and sarcopenia.

A growing body of evidence shows that women with HIV are at increased risk of developing metabolic disorders compared to men, including body weight gain and obesity, type 2 diabetes mellitus, dyslipidemia, bone loss, and sarcopenia, while men with HIV are at higher risk for hepatosteatosis and hepatic fibrosis.

Future work should prioritize the adequate representation of women in HIV clinical studies. Understanding sex-specific mechanisms underlying metabolic dysfunction in PWH is imperative so that interventions can be developed to address a growing global epidemic of metabolic diseases.
