Abstract:

Objective:

We sought to determine the incidence and factors associated with development of diabetes mellitus (DM) in older HIV-infected individuals.

Research design and methods:

We analyzed data from people living with HIV (PLWH) ≥50 years of age enrolled in a large urban HIV outpatient clinic in Vancouver, British Columbia. Patients were categorized as having DM if they had random blood sugar ≥11.1 mmol/L, fasting blood sugar ≥7 mmol/L, HbA1C ≥6.5%, antidiabetic medication use during the follow-up period, or medical chart review confirming diagnosis of DM. We estimated the probability of developing DM, adjusting for demographic and clinical factors, using a logistic regression model.

Results:

Among 1065 PLWH followed for a median of 13 years (25th and 75th percentile (Q1-Q3): 9-18), the incidence of DM was 1.61/100 person-years follow-up. In the analysis of factors associated with new-onset DM (n=703), 88% were male, 38% had a history of injection drug use, 43% were hepatitis C coinfected, and median body mass index was 24 kg/m² (Q1-Q3: 21-27). Median age at antiretroviral therapy (ART) initiation was 48 years (Q1-Q3: 43-53) and at DM diagnosis was 55 years (Q1-Q3: 50-61). Patients who started ART in 1997-1999 and had a longer exposure to older ART were at the highest risk of developing DM.

Conclusions:

Among PLWH aged ≥50 years, the incidence of DM was 1.39 times higher than men in the general Canadian population of similar age. ART initiated in the early years of the epidemic and exposure to older ART appeared to be the main drivers of the development of DM.
