The aim of this study was to investigate the interconnections between specific quality-of-life domains in patients with obesity and high or low physical performance using a network approach.
716 consecutive female and male patients (aged 18-65 years) with obesity seeking weight-loss treatment were included. The 36-item Short Form Health Survey (SF-36) and the six-minute walking test (6MWT) were used to assess quality of life and physical performance, respectively. The sample was split into two groups according to the distance walked in the 6MWT. Network structures of the SF-36 domains in the two groups were assessed and compared, and the relative importance of individual items in the network structures was determined using centrality analyses.
35.3% ( = 253) of participants covered more distance than expected, and 64.7% ( = 463) did not. Although low-performing patients showed lower quality of life domain scores, the network structures were similar in the two groups, with the SF-36 Vitality representing the central domain in both networks. Mental Health was a node with strong connections in patients who walked less distance.
These findings indicate that psychosocial variables represent the most influential and interconnected features as regards quality of life in both groups.
本研究旨在通过网络方法研究肥胖患者中特定生活质量领域与高或低身体表现之间的相互关系。
纳入了 716 名连续的女性和男性肥胖患者（年龄 18-65 岁），他们正在寻求减肥治疗。使用 36 项简短健康调查（SF-36）和六分钟步行测试（6MWT）分别评估生活质量和身体表现。根据 6MWT 中行走的距离将样本分为两组。评估和比较两组 SF-36 域的网络结构，并使用中心性分析确定网络结构中各个项目的相对重要性。
35.3%（=253）的参与者走的距离超过预期，64.7%（=463）的参与者没有。尽管表现不佳的患者生活质量领域得分较低，但两组的网络结构相似，SF-36 活力在两个网络中均代表中心域。心理健康是距离较短的患者中具有强连接的节点。
这些发现表明，心理社会变量代表了两组生活质量中最具影响力和相互关联的特征。
