Abstract

Weight loss may benefit older adults with obesity. However, it is unknown whether individuals with different frailty phenotypes have different outcomes following weight loss. Community-dwelling adults aged ≥65 (n = 53) with a body mass index ≥30 kg/m² were recruited for a six-month, single-arm, technology-based weight loss study. A 45-item frailty index identified frailty status using subjective and objective measures from a baseline geriatric assessment. At baseline, n = 22 participants were classified as pre-frail (41.5%) and n = 31 were frail (58.5%), with no differences in demographic characteristics. While weight decreased significantly in both groups (pre-frail: 90.8 ± 2.7 kg to 85.5 ± 2.4 kg (p < 0.001); frail: 102.7 ± 3.4 kg to 98.5 ± 3.3 kg (p < 0.001), no differences were observed between groups for changes in weight (p = 0.30), appendicular lean mass/height² (p = 0.47), or fat-free mass (p = 0.06). Older adults with obesity can safely lose weight irrespective of frailty status using a technology-based approach. Further investigation is needed to determine whether the impact of specific lifestyle interventions differ by frailty status.

按虚弱状态划分的体重或身体成分变化：试点研究

减肥可能对患有肥胖症的老年人有益。然而，不同虚弱表型的人在减肥后是否会有不同的结果，目前还不得而知。我们招募了年龄≥65岁、体重指数≥30 kg/m2、居住在社区的成年人（n = 53），开展了一项为期六个月、单臂、基于技术的减肥研究。通过基线老年评估中的主观和客观指标，45 项虚弱指数可确定虚弱状态。基线时，n = 22 名参与者被归类为虚弱前期（41.5%），n = 31 名参与者被归类为虚弱期（58.5%），两组的人口统计学特征无差异。两组参与者的体重均有明显下降（虚弱前：90.8 ± 2.7 千克降至 85.5 ± 2.4 千克（P = 0.30）），但瘦体重/身高2（P = 0.47）或无脂肪体重（P = 0.06）均有明显下降。无论身体是否虚弱，患有肥胖症的老年人都可以使用基于技术的方法安全地减轻体重。还需要进一步调查，以确定特定生活方式干预措施的影响是否因虚弱状况而异。

期刊介绍： The Journal of Nutrition in Gerontology and Geriatrics publishes original research studies that are directly relevant to clinical and community nutrition issues that affect older adults. Epidemiologic and community-based studies are suitable for JNE, as are well-controlled clinical trials of preventive and therapeutic nutritional interventions. The Journal of Nutrition in Gerontology and Geriatrics invites papers on a broad array of topics in the nutrition and aging field, including but not limited to studies of: preventive nutrition, nutritional interventions for chronic disease, aging effects on nutritional requirements, nutritional status and dietary intake behaviors, nutritional frailty and functional status, usefulness of supplements, programmatic interventions, transitions in care and long term care, and community nutrition issues.
