Muscle strength can be a predictor of depressive symptoms among the elderly. We conducted a prospective study aiming to examine the association between change of handgrip strength and the incidence risk of depressive symptoms among Chinese female college students. Handgrip strength was used as a representative indicator of skeletal muscle strength, and a handheld digital smedley dynamometer was applied to measure handgrip strength. We also used the 20-item Zung self-rating depression scale to evaluate depressive status, and a score of ≥50 indicated moderate-to-severe depressive symptoms. During a 1-year follow-up period, the incidence of depressive symptoms is 10.7%. Multivariate logistic regressions analysis revealed that the multivariable-adjusted ORs (95% CI) of depressive symptoms for the categories of handgrip strength change was 1.00 (reference) for group 1, 0.57 (0.28, 1.19) for group 2, 0.41 (0.19, 0.89) for group 3 and 0.33 (0.11, 0.99) for group 4 ( = 0.018). This study indicated that change of handgrip strength level over one-year period is negatively associated with risk of depressive symptoms among Chinese female college students.
肌肉力量可以预测老年人的抑郁症状。我们进行了一项前瞻性研究，旨在检验中国女大学生握力变化与抑郁症状发生风险之间的关系。握力作为骨骼肌力量的代表性指标，使用手持式数字 Smedley 测力计测量握力。我们还使用 20 项 Zung 自评抑郁量表评估抑郁状况，得分≥50 表示中重度抑郁症状。在 1 年的随访期间，抑郁症状的发生率为 10.7%。多变量逻辑回归分析显示，握力变化组别的多变量调整后 OR（95%CI）为 1.00（参考）组 1、0.57（0.28，1.19）组 2、0.41（0.19，0.89）组 3 和 0.33（0.11，0.99）组 4（=0.018）。这项研究表明，中国女大学生在一年期间握力水平的变化与抑郁症状的风险呈负相关。
