This study aimed to examine the association of relative handgrip strength (RHGS) with depressive mood and suicidal ideation.
A cross-sectional study was conducted among 2167 men and 2643 women (aged 50.9 years ± 16.7 years) who participated in the 2015 Korean National Health and Nutrition Examination Survey. RHGS was defined by the handgrip strength/body mass index (BMI) ratio. Depressive mood and suicidal ideation were assessed using self-reported questionnaires. Logistic regression analysis was conducted after adjusting for sex, concurrent illness, age, education, income, smoking status, alcohol use, physical activity, and depressive mood (in the analysis for suicidal ideation).
Among participants, 4.0% men and 5.7% women reported serious suicidal ideation while 9.5% men and 16.0% women reported serious depressive mood. After adjusting for confounding factors, RHGS was associated with depressive mood (odds ratio [95% confidence interval] per RHGS [kg/BMI], 0.82 [0.69-0.99]) and suicidal ideation (0.73 [0.54-0.99]). In sex-specific relationship, RHGS was associated with depressive mood and suicidal ideation in women (0.71 [0.55-0.93] and 0.54 [0.34-0.85], respectively) but not in men.
Poorer RHGS indicates higher risk of depressive mood as well as suicidal ideation regardless of depressive mood among women.
本研究旨在探讨相对握力（RHGS）与抑郁情绪及自杀意念之间的关联。
对参加2015年韩国国民健康与营养检查调查的2167名男性和2643名女性（年龄50.9岁±16.7岁）进行了一项横断面研究。RHGS通过握力/体重指数（BMI）比值来定义。抑郁情绪和自杀意念通过自我报告问卷进行评估。在对性别、并发疾病、年龄、教育程度、收入、吸烟状况、饮酒情况、身体活动以及抑郁情绪（在自杀意念分析中）进行调整后，进行了逻辑回归分析。
在参与者中，4.0%的男性和5.7%的女性报告有严重自杀意念，而9.5%的男性和16.0%的女性报告有严重抑郁情绪。在对混杂因素进行调整后，RHGS与抑郁情绪（每RHGS[kg/BMI]的优势比[95%置信区间]，0.82[0.69 - 0.99]）和自杀意念（0.73[0.54 - 0.99]）相关。在性别特异性关系中，RHGS与女性的抑郁情绪和自杀意念相关（分别为0.71[0.55 - 0.93]和0.54[0.34 - 0.85]），但与男性无关。
无论女性是否有抑郁情绪，较差的RHGS表明抑郁情绪以及自杀意念的风险更高。
