Older adults with disease and disability are particularly vulnerable to experiencing more severe consequences of depression. The purpose of the present study is to investigate the relationship between disease comorbidities (number of disease: ND0, 1 disease: ND1 and 2 or more diseases: ND ≥ 2), hand grip strength (low HGS and high HGS), and the prevalence of depression in Korean older adults. Data from the living profiles of older people survey that was conducted by the ministry of health and welfare in Korea were utilized. Data for 6107 females and 4347 males were appropriate for statistical tests. The results demonstrated that depression was more prevalent as ND increased ( < 0.01). In addition, HGS appeared lower as ND increased in both male ( < 0.01) and female subjects ( < 0.01). Furthermore, relative to ND0 and low HGS, ND0 and high HGS showed a ~65% reduction in the prevalence of depression ( < 0.01). After adjusting for age, the prevalence of depression was reduced by ~60% in the subgroup with ND0 and high HGS relative to ND0 and low HGS ( < 0.01). These data demonstrate that muscular strength indices such as HGS may be useful when assessing depression in older adults. Further research in this area is warranted.
患有疾病和残疾的老年人尤其容易受到抑郁症更严重后果的影响。本研究的目的是调查疾病合并症（无疾病：ND0，一种疾病：ND1，两种或更多疾病：ND≥2）、手握力（低 HGS 和高 HGS）与韩国老年人抑郁患病率之间的关系。本研究使用了由韩国保健福祉部进行的老年人生活概况调查的数据。共有 6107 名女性和 4347 名男性的数据适合进行统计检验。结果表明，随着 ND 的增加，抑郁的患病率也随之增加（<0.01）。此外，男性（<0.01）和女性（<0.01）的 HGS 随着 ND 的增加而降低。此外，与 ND0 和低 HGS 相比，ND0 和高 HGS 使抑郁的患病率降低了约 65%（<0.01）。在调整年龄后，与 ND0 和低 HGS 相比，ND0 和高 HGS 的亚组中，抑郁的患病率降低了约 60%（<0.01）。这些数据表明，HGS 等肌肉力量指标在评估老年人的抑郁症状时可能有用。需要在这一领域进行进一步的研究。
