Summary   Background  Human immunodeficiency virus infection and obesity are pro‐inflammatory conditions that, when occurring together, may pose a synergistic risk for diabetes and cardiovascular disease.    Purpose  The aim of the current study was (i) to document the prevalence of obesity in HIV+ patients treated at the Miriam Hospital Immunology Center (Providence, RI) and (ii) to investigate the relationship between obesity and comorbidities.    Methods  The study population consisted of 1,489 HIV+ adults (70% men; average age 48 ± 11 years) treated between 01/01/2012 and 06/30/2014. Separate logistic regressions tested the associations between overweight and obesity and comorbid diagnoses (diabetes, hypertension and cardiovascular disease), as compared with normal weight. Covariates included age, gender and smoking status.    Results  Approximately 37% of patients were overweight (body mass index 25.0–29.9), and an additional 28% were obese (body mass index ≥30.0). Obesity was associated with higher odds of comorbid diabetes (OR = 3.26, CI = 1.98–5.39) and hypertension (OR = 2.11, CI = 1.49–2.98). There was no significant association between obesity and the presence of cardiovascular disease (OR = 1.12, CI = 0.66–1.90). Overweight was associated only with higher odds of comorbid diabetes (OR = 1.72; CI = 1.02–2.88).    Conclusion  Our findings demonstrate a heightened risk of comorbidities in overweight and obese HIV+ patients. Future studies should investigate whether weight loss interventions for this population can reduce cardiovascular and metabolic risk factors as they do in other populations.
