        abstract = {OBJECTIVE: Excessive weight gain has been reported with integrase strand transfer inhibitors (INSTIs). We evaluated weight changes in virologically-suppressed adults with HIV who switched from non-INSTI regimens to raltegravir- or dolutegravir-containing antiretroviral therapy. DESIGN: Retrospective single-centre cohort. METHODS: Adults who switched to raltegravir or dolutegravir before or between January-2015 and October-2017 were identified. Virologically-suppressed, treatment-experienced ({$\ge$}2 years) individuals, {$\ge$}6 months on INSTI, with weight measurements {$\leq$}2years pre- and post-switch were included. Our analysis used a random effects model with linear slope pre- and post-INSTI with adjustment for age, gender, ethnicity, pre-switch-regimen (protease inhibitor vs. non-protease inhibitor), and raltegravir vs. dolutegravir use. RESULTS: 378 individuals, 81.2\% male, 70.1\% white ethnicity, median age of 49 years, median of four weight measurements per participant, and median weight and body mass index (BMI) at switch, of 76.6 kg, and 25.3 kg/m respectively were included. Weight increased by an average of 0.63 kg/year (95\% CI 0.17-1.09) pre-switch with no overall change in rate of weight gain post-switch [+0.05 kg/year (-0.61-0.71, p = 0.88)]. In our adjusted model, a transition from minimal weight change to weight gain post-switch was isolated to older individuals though this lacked statistical significance [e.g. +1.59 kg/year (-0.26-3.45) if aged 65 years]. Our findings did not differ by gender, ethnicity, pre-switch regimen, or raltegravir vs. dolutegravir. Similar results were seen for BMI and after adjusting for fixed nucleoside/nucleotide reverse transcriptase inhibitor backbone. CONCLUSION: We found no clear evidence of an overall increase in rate of weight gain following switch to INSTI in virologically-suppressed individuals.},
