Real-World Assessment of Weight Change in African American Females and Hispanics with HIV-1 After Initiating Integrase Strand-Transfer Inhibitors or Protease Inhibitors
**Background:** Studies have shown an increase in weight among people living with HIV (PLWH) who initiated integrase strand transfer inhibitors (INSTI). However, weight gain with INSTI-based regimens vs other regimens in females or racial/ethnic minorities is poorly understood. **Objective:** This...

| description | **Background:** Studies have shown an increase in weight among people living with HIV (PLWH) who initiated integrase strand transfer inhibitors (INSTI). However, weight gain with INSTI-based regimens vs other regimens in females or racial/ethnic minorities is poorly understood.
**Objective:** This study assessed differences in weight gain among treatment-naïve, female, African Americans and Hispanics after initiating INSTI-based vs protease inhibitor (PI)-based regimens.
**Methods:** This retrospective, observational cohort study included data from the Optum® deidentified Electronic Health Record Database. Female African Americans or Hispanics initiating INSTI- or PI-based regimens between January 1, 2015, and December 31, 2018 (first prescription was index date), with ≥12-month baseline and follow-up periods, ≥1 weight measure during each period, and no prior antiretroviral (ARV) use were included. Inverse probability of treatment weighting was used to reduce selection bias and improve cohort comparability. Multivariable models were used to compare absolute weight/body mass index (BMI) changes and proportion of patients with weight/BMI increases from pre- to post-index (last measure between the 4th and 12th months post-index).
**Results:** Weighted cohorts included 3407 African American females (INSTI, 1704; PI, 1703) and 3711 Hispanics (INSTI, 1865; PI, 1846) PLWH. Mean time to follow-up weight measure was ~9.5 months. Among female African Americans, INSTI initiators had a 1.5 kg greater mean weight gain (2.1 kg vs 0.6 kg; P = 0.033), and a higher proportion with ≥5% weight gain (32% vs 29%; odds ratio \[OR]=1.2; 95% CI \[1.0-1.4]) than PI initiators. Among Hispanics, INSTI and PI initiators had similar mean increases in weight (2.1 and 1.8 kg, respectively), but INSTI initiators had a higher proportion with ≥5% weight gain (31% vs 27%; OR=1.2; 95% CI \[1.1-1.4]). Female African American INSTI initiators were more likely to shift from normal or overweight to a worse BMI classification. Hispanic INSTI initiators were less likely to shift from normal BMI to overweight but more likely to shift from normal or overweight to obese.
**Conclusion:** In a real-world setting, INSTI-based regimens were associated with greater weight gain for treatment-naïve female African Americans, compared with PI-based regimens. Differences between regimens were less consistent for Hispanics. These results may inform ARV choice for PLWH who are at risk for ARV-related weight gain. |
