Obesity affects health-related quality of life (QoL); however, their relationship among elderly Asians is not well known.
Relationship of domain-specific QoL with body mass index (BMI) and waist circumference and the sex differences were investigated using a nationally representative sample of elderly Korean population.
In the Korea National Health and Nutrition Examination Survey phase VII (2016-2018), 3659 adults aged ≥ 65 years (1551 men and 2108 women) participated. BMI and waist circumference were classified according to Asian- and Korean-specific criteria. QoL was evaluated using the European Quality of Life Scale-Five Dimensions (EQ-5D). Multivariable logistic regressions were used to examine the relationship of QoL with BMI and waist circumference.
Men with BMI < 18.5 kg/m and ≥ 25.0 kg/m had a significant association with poor QoL in mobility and self-care, but no relationship was found with the other domains. Women with BMI ≥ 25.0 kg/m had poor QoL in mobility and self-care, and those with BMI ≥ 30.0 kg/m had poor QoL in usual activities and pain/discomfort. There was no significant association with anxiety/depression. Both elderly men and women with abdominal obesity had a significant association with poor QoL in mobility, self-care, usual activities, and pain/discomfort; however, there was no significant relationship with waist circumference and anxiety/depression.
The association between QoL and BMI was different according to sex and the domains of QoL. Domain-specific QoL should be considered in the management of body weight of the elderly.
肥胖会影响与健康相关的生活质量（QoL）；然而，其在亚洲老年人中的关系尚不清楚。
使用具有代表性的韩国老年人样本，调查特定领域的 QoL 与体重指数（BMI）和腰围的关系以及性别差异。
在韩国国家健康和营养检查调查第七阶段（2016-2018 年）中，有 3659 名年龄≥65 岁的成年人（1551 名男性和 2108 名女性）参与。根据亚洲和韩国特定标准对 BMI 和腰围进行分类。使用欧洲生活质量量表-五个维度（EQ-5D）评估 QoL。使用多变量逻辑回归来检查 QoL 与 BMI 和腰围的关系。
男性 BMI<18.5 kg/m2 和≥25.0 kg/m2 与移动和自理方面的 QoL 较差有显著关联，但与其他领域没有关系。女性 BMI≥25.0 kg/m2 与移动和自理方面的 QoL 较差有关，而 BMI≥30.0 kg/m2 与日常活动和疼痛/不适方面的 QoL 较差有关。与焦虑/抑郁没有显著关联。无论男性还是女性，腹部肥胖都与移动、自理、日常活动和疼痛/不适方面的 QoL 较差有显著关联；然而，与腰围和焦虑/抑郁没有显著关系。
QoL 与 BMI 的关联因性别和 QoL 的特定领域而异。在老年人的体重管理中应考虑特定领域的 QoL。
