We recently reported that a 12-week internet weight loss program produced greater weight losses than education control in overweight/obese people living with HIV (PLWH) (4.4 kg vs 1.0 kg; p < 0.05). This manuscript presents the changes in diet, physical activity, behavioral strategies, and cardio-metabolic parameters. Participants (N = 40; 21 males, 19 females) were randomly assigned to an internet behavioral weight loss (WT LOSS) program or internet education control (CONTROL) and assessed before and after the 12-week program. Compared to CONTROL, the WT LOSS arm reported greater use of behavioral strategies, decreases in intake (- 681 kcal/day; p = 0.002), modest, non-significant, increases in daily steps (+ 1079 steps/day) and improvements on the Healthy Eating Index. There were no significant effects on cardio-metabolic parameters. The study suggests that a behavioral weight loss program increases the use of behavioral strategies and modestly improves dietary intake and physical activity in PLWH. Further studies with larger sample sizes and longer follow-up are needed.Clinical Trials Registration: NCT02421406.
我们最近报道称，一项为期 12 周的互联网减肥计划在超重/肥胖的 HIV 感染者（PLWH）中产生的体重减轻效果优于教育对照组（4.4 公斤对 1.0 公斤；p<0.05）。本文介绍了饮食、身体活动、行为策略和心血管代谢参数的变化。参与者（N=40；21 名男性，19 名女性）被随机分配到互联网行为减肥（WT LOSS）组或互联网教育对照组（CONTROL），并在 12 周计划前后进行评估。与 CONTROL 相比，WT LOSS 组报告称更多地使用了行为策略，饮食摄入量减少（每天减少 681 卡路里；p=0.002），日常步数适度增加（每天增加 1079 步），健康饮食指数有所改善。心血管代谢参数没有显著变化。该研究表明，行为减肥计划增加了行为策略的使用，并适度改善了 PLWH 的饮食摄入和身体活动。需要更大样本量和更长随访时间的进一步研究。临床试验注册：NCT02421406。
