Perceptions? administered before weight gain information leaflet and consent • 69 participants surveyed by 15 July 2019: 51 women, 17 men • No discontinuations for weight gain: most participant’s estimation of their weight gain was similar to the actual weight gain, with a few wild exceptions • 8 women reported unhappiness with weight gain (one actually had lost 1.3 kg); 3 had actually gained <5%, while 4 had >10% weight gain – 2 of those who gained >10% of their baseline weight expressed that they were very unhappy • 6 women participants reported uneven weight gain: 3 abdominal, 2 upper body, 1 hip area, and 1 lower body • 2 men reported unhappiness with weight loss (verified weight loss for both) • Most participants were happy with the weight gain, even though they had to get new clothes as their pre-ART clothes could not fit anymore – Some viewed the weight gain as “return to health” although they had not reported weight loss at screening Source: Dr Simiso Sokhela Adapted from: Hill A, et al. IAS 2019; Mexico City, Mexico. Slides MOAX0102LB. ADVANCE: Factors Associated Obesity and Weight Gain (2/2) • After multivariable analysis, associated factors were: – Treatment-emergent obesity: • TAF/FTC+DTG, baseline CD4+ count, baseline VL, and baseline BMI • When baseline BMI was excluded the following predictors were also significant: • Female sex, South African nationality, and employment – ≥10% increase in body weight: • TAF/FTC+DTG, baseline CD4+ count, baseline VL, female sex, age, and baseline weight Adapted from: Hill et al.
