Background It remains unclear whether muscle strength, which reduces cardiovascular (CV) risk in adults, is associated with similar protection in Asian adolescents. This study investigated the association between handgrip strength and CV health in a large Korean sample of school-age adolescents. Methods We performed a cross-sectional analysis of adolescents aged 10-18 years (n=4,018) from the Korean National Health and Nutrition Survey between 2014 and 2017. Handgrip strength was measured using a dynamometer. CV risk factors include waist circumference, blood pressure, fasting glucose or hemoglobin A1c, and lipid levels. Logistic regression models were applied with adjustment for potential confounders. Results The mean age of participants was 14.0 years, and 53.6% were boys. Mean handgrip strength was 30.4 kg for boys and 22.0 kg for girls. Boys more frequently had high systolic blood pressure and impaired fasting glucose, whereas girls more frequently had low high-density lipoprotein cholesterol. Multivariate logistic regression analysis revealed that in boys only, handgrip strength was negatively associated with central obesity and hypertriglyceridemia and positively associated with higher systolic blood pressure. Conclusion Handgrip strength is independently associated with some CV risk factors only in boys.
在成年人中，肌肉力量可降低心血管（CV）风险，但不清楚其是否与亚洲青少年具有类似的保护作用。本研究旨在调查在一个大型的韩国学龄青少年样本中，握力与 CV 健康之间的关系。
我们对 2014 年至 2017 年间参加韩国国家健康和营养调查的 10-18 岁青少年（n=4018）进行了横断面分析。使用测力计测量握力。心血管风险因素包括腰围、血压、空腹血糖或糖化血红蛋白和血脂水平。应用逻辑回归模型调整了潜在混杂因素。
参与者的平均年龄为 14.0 岁，其中 53.6%为男性。男性的平均握力为 30.4kg，女性为 22.0kg。男孩更常出现收缩压升高和空腹血糖受损，而女孩更常出现高密度脂蛋白胆固醇降低。多变量逻辑回归分析显示，仅在男孩中，握力与中心性肥胖和高三酰甘油血症呈负相关，与较高的收缩压呈正相关。
握力仅与男孩的一些心血管风险因素独立相关。
