Determine if asymmetric handgrip strength exists in childhood and adulthood and quantify the degree of tracking of handgrip strength asymmetry over time.
Participants from the Childhood Determinants of Adult Health Study had their right and left handgrip strength measured using handgrip dynamometry in childhood (1985: 9-15 y), young adulthood (2004-06: 26-36 y) and/or mid-adulthood (2014-19: 36-49 y). Handgrip strength asymmetry was calculated as: strongest handgrip strength/strongest handgrip strength on the other hand. Participants were categorised based on the degree of their asymmetry (0.0%-10.0%, 10.1%-20.0%, 20.1%-30.0%, >30.0%). Tracking was quantified using Spearman's correlations and log binomial regression.
Handgrip strength asymmetry was present in childhood and adulthood (>30.0% asymmetry: childhood = 6%, young adulthood = 3%, mid-adulthood = 4%). Handgrip strength asymmetry did not track between childhood and young- (r = 0.06, 95% CI = -0.02, 0.12) and mid-adulthood (r = 0.01, 95% CI = -0.09, 0.10). Tracking was more apparent between young- and mid-adulthood (r = 0.16, 95% CI = 0.09, 0.22). Participants with >30.0% asymmetry were at greater risk to maintain this status between childhood and young- (RR = 3.53, 95% CI = 1.15, 10.87) and mid-adulthood (RR = 2.14, 95% CI = 0.45, 10.20).
Although handgrip strength asymmetry tracked relatively poorly, asymmetric handgrip strength was apparent in children and adults. Handgrip strength asymmetry does not exclusively affect older adults and should be considered in protocols to better understand its role across the life course.
确定儿童和成年期是否存在非对称握力，并量化握力不对称随时间的跟踪程度。
来自儿童期决定成人健康研究的参与者在儿童期（1985 年：9-15 岁）、青年期（2004-06 年：26-36 岁）和/或中年期（2014-19 年：36-49 岁）使用握力测力计测量其右手和左手握力。握力不对称性的计算方法为：最强握力/另一只手的最强握力。根据不对称程度将参与者分为几类（0.0%-10.0%、10.1%-20.0%、20.1%-30.0%、>30.0%）。使用 Spearman 相关系数和对数二项式回归来量化跟踪。
儿童和成年期都存在握力不对称性（>30.0%不对称：儿童期=6%，青年期=3%，中年期=4%）。儿童期和青年期（r=0.06，95%CI=-0.02，0.12）和中年期（r=0.01，95%CI=-0.09，0.10）之间的握力不对称性并没有跟踪。青年期和中年期之间的跟踪更为明显（r=0.16，95%CI=0.09，0.22）。>30.0%不对称的参与者在儿童期和青年期（RR=3.53，95%CI=1.15，10.87）和中年期（RR=2.14，95%CI=0.45，10.20）之间保持这种状态的风险更高。
尽管握力不对称性的跟踪相对较差，但儿童和成年人都存在握力不对称。握力不对称性不仅影响老年人，在整个生命过程中，应该在协议中考虑它，以更好地理解它的作用。
