Handgrip strength (HGS) is a well-established indicator of muscle strength and a reasonable clinical predictor of metabolic health and diseases. This study explores the association between relative muscular strength and abdominal obesity (AO) in healthy Chilean adults. A convenience sample was recruited ( = 976) between 2018 and 2020. The HGS was determined by dynamometry. The anthropometry (weight, height, waist, and mid-arm circumference) and physical activity were also measured. The relative HGS (RHGS) was calculated by dividing the maximum HGS of the dominant hand by the body mass index. The AO was defined as a waist circumference (WC) >88 cm for women, and >102 cm for men. From the sample, 52.6% were women, 56.4% had excessive weight, and 42.7% had AO. The absolute and RHGS were greater in men compared to women ( < 0.001) and were decreased with age in both sexes. We observed a moderate negative correlation between WC and RHGS ( = -0.54, and = -0.53, for men and women, respectively). The RHGS was lower in individuals with AO, independent of age and sex ( < 0.05). For each cm increase in WC, the odds of low RHGS (<25th percentile) increased by 12 and 9% for men and women, respectively. The AO is related to higher odds for low RHGS (OR: 1.72; 95% CI: 1.23-2.41). In our sample of healthy adults, a higher AO was associated with a lower muscle strength measured by dynamometry.
握力（HGS）是一种公认的肌肉力量指标，也是代谢健康和疾病的合理临床预测指标。本研究探讨了智利健康成年人相对肌肉力量与腹部肥胖（AO）之间的关联。在2018年至2020年期间招募了一个便利样本（n = 976）。通过握力计测定握力。还测量了人体测量指标（体重、身高、腰围和上臂围）以及身体活动情况。相对握力（RHGS）通过优势手的最大握力除以体重指数来计算。AO定义为女性腰围（WC）>88 cm，男性腰围>102 cm。在样本中，52.6%为女性，56.4%体重超标，42.7%患有AO。男性的绝对握力和相对握力均高于女性（P < 0.001），且两性的握力均随年龄增长而下降。我们观察到WC与RHGS之间存在中度负相关（男性r = -0.54，女性r = -0.53）。无论年龄和性别如何，AO患者的RHGS较低（P < 0.05）。WC每增加1 cm，男性和女性低RHGS（<第25百分位数）的几率分别增加12%和9%。AO与低RHGS的较高几率相关（OR：1.72；95% CI：1.23 - 2.41）。在我们的健康成年人样本中，较高的AO与通过握力计测量的较低肌肉力量相关。
