Abstract: Objective To study the correlation between body composition and grip strength of school-age children and adolescents,in order to provide evidence for maintaining appropriate body composition when giving interventions to school-age obese children. Methods A questionnaire survey (lifestyle,dietary and exercise),bioelectrical impedance analysis of body composition and dominant hand grip strength tests were conducted among 15 118 school-age children aged 6-16 years in Beijing in 2018.Partial correlation,and multiple linear regression were used to analyze the correlation of body composition indicators and handgrip strength. Results The level of grip strength of children and adolescents in Beijing gradually increased with age.Grip strength of the normal weight group in boys increased from (9.7±2.6)kg in 6-8 years age group to (40.0±7.1)kg in 15-16 years age group,and grip strength of the normal weight group in girls increased from (8.9±2.6)kg in 6~8 years age group to (25.0±4.4)kg in 15-16 years age group,which was consistent with the change trend of skeletal muscle index of the upper limbs,and handgrip strength of boys was higher than that of girls.Adjusted for some related factors,the higher the fat free mass index(boys:r=0.597,girls:r=0.424)and the skeletal muscle index(boys:r=0.258,girls,r=0.102) were,the higher grip strength was(P<0.05). Conclusion Grip strength can reflect the trend of skeletal muscle.Reducing fat mass and increasing fat free mass can improve the grip strength.

摘要: 目的 研究学龄儿童青少年体成分与握力的相关性,对学龄肥胖儿童干预过程中维持合适的体成分具有重要意义。方法 2018年对北京市15 118名6~16岁学龄儿童进行问卷调查(生活方式、膳食、运动)、生物电阻抗体成分检测和优势手握力检测,并采用偏相关、多元线性回归对握力与体成分指标的相关性进行分析。结果 北京市儿童青少年的握力水平随年龄增长逐渐升高,男童正常体重组握力水平由6~8岁组的(9.7±2.6)kg增长到15~16岁组的(40.0±7.1)kg,女童正常体重组由6~8岁组的(8.9±2.6)kg增长到15~16岁组的(25.0±4.4)kg,与上肢骨骼肌质量指数变化趋势一致;男生高于女生;调整相关因素后,瘦体重质量指数及上肢骨骼肌质量指数与握力水平均呈正相关(男童:r=0.597,0.258;女童:r=0.424,0.102,P<0.05)。结论 握力可反映骨骼肌水平变化趋势。增加瘦体重,减少脂肪可提高握力水平。
