我们对老年人进行了一项前/后、单臂、非随机、多组分减肥干预的事后分析。招募了53名年龄≥65岁、体重指数≥ 30 kg/m2的老年人参加为期六个月的远程监控和视频会议的处方干预，其中包括个人和团体主导的注册营养师营养和物理治疗课程。我们使用SECA 514生物电阻抗分析仪评估体重、身高和身体成分。平均年龄为72.9±3.9岁（70%为女性），所有患者均患有≥2种慢性疾病。在具有完整数据的患者（n=30）中，我们观察到体重减轻4.6± 3.5 kg，脂肪量减轻6.1± 14.3 kg（1.9%），内脏脂肪减少0.78± 1.69 L（均p<0.05）。无脂体重（−3.4kg±6.8，p=0.19）、无脂体重（−0.25±1.83，p=0.22）和握力（+3.46 7. 89，p=0.56）没有显著变化。这些变量在通过5%重量损失分层后保持不变。我们的干预导致了显着的身体和内脏脂肪损失，同时保持无脂肪和无脂肪的瘦肌肉质量。本文的补充材料可在10.14283/jfa.2022.15获得，授权用户可访问。
We conducted a post-hoc analysis of a pre/post, single-arm, nonrandomized, multicomponent weight loss intervention in older adults. Fifty-three older adults aged ≥65 with a body mass index ≥ 30 kg/m2 were recruited to participate in a six-month, remote monitoring and video-conferencing delivered, prescriptive intervention consisting of individual and group-led registered dietitian nutrition and physical therapy sessions. We assessed weight, height, and body composition using a SECA 514 bioelectrical impedance analyzer. Mean age was 72.9±3.9 years (70% female) and all had ≥2 chronic conditions. Of those with complete data (n=30), we observed a 4.6±3.5kg loss in weight, 6.1±14.3kg (1.9%) loss in fat mass, and 0.78±1.69L loss in visceral fat (all p<0.05). Fat-free mass (−3.4kg±6.8, p=0.19), appendicular lean mass (−0.25±1.83, p=0.22), and grip strength (+3.46±7.89, p=0.56) did not significantly change. These variables were preserved after stratifying by 5% weight loss. Our intervention led to significant body and visceral fat loss while maintaining fat-free and appendicular lean muscle mass.
