In this study, we evaluated the correlation of four types of hand strength (hand grip, tip pinch, palmar pinch and key pinch) with age, sex, body weight, body height, body mass index, triceps skinfold thickness, mid-arm circumference and mid-forearm circumference in a group of 437 Chinese adults (195 men and 242 women) who ranged in age from 28 to 78 years. All of the hand strengths studied correlated positively with gender, body weight, body height, mid-arm and mid-forearm circumference and negatively with age and triceps skinfold thickness in the analyses of simple correlation coefficients. Men were found to be more powerful than women in all hand strength types in different age groups. The magnitude of strength decline with age was more prominent in grip strength than pinch strength including palmar, tip and key. Stepwise multiple regression analyses showed that sex, age and mid-forearm circumference were most predictive of all types of hand strength. Body height was an additional independent predictor of grip and palmar pinch. Body mass index, body weight, mid-arm circumference and triceps skinfold thickness were not independent predictors associated with hand strength.
在本研究中，我们评估了437名年龄在28至78岁之间的中国成年人（195名男性和242名女性）的四种手部力量（握力、指尖捏力、掌部捏力和钥匙捏力）与年龄、性别、体重、身高、体重指数、肱三头肌皮褶厚度、上臂中部周长和前臂中部周长之间的相关性。在简单相关系数分析中，所有研究的手部力量均与性别、体重、身高、上臂中部和前臂中部周长呈正相关，与年龄和肱三头肌皮褶厚度呈负相关。发现在不同年龄组中，男性在所有手部力量类型上都比女性更强。随着年龄增长，握力的力量下降幅度比包括掌部、指尖和钥匙捏力在内的捏力更为显著。逐步多元回归分析表明，性别、年龄和前臂中部周长是所有类型手部力量的最主要预测因素。身高是握力和掌部捏力的另一个独立预测因素。体重指数、体重、上臂中部周长和肱三头肌皮褶厚度不是与手部力量相关的独立预测因素。
