Abstract As an index for many adverse health outcomes, normative values on handgrip strength are established for many populations. The aim of this study was to establish handgrip strength (HGS) norms for the Iranian population and to compare them with other existing norms. Related variables affecting HGS were also determined in order to provide appropriate prediction models. The sample consisted of 4282 Iranian 20–80 years adults; divided into 5-year intervals, male/female and dominant/non-dominant hand. Results were compared to consolidated data and those of some other countries. To ensure a valid and comparable dataset, HGS was measured using the JAMAR® hydraulic dynamometer following the standardized procedure. Hand length, palm length, palm width, forearm length, wrist circumference, forearm circumference, height and weight were measured, and BMI was calculated. HGS norms for Iranian adults were established. Inverted U-shaped lifespan profiles were found with mean maximum values of about 53 kg for males (35–39 years) and 31 kg for females (40–44 years). Two regression models (by hand dominance) were developed. The mean values of HGS in Iran were weaker than consolidated norms but greater than in some Asian countries. Applying normative data specific to each population is more accurate than international or multinational norms. It is recommended to investigate the causes of accelerated age-related decline in HGS of Iranian elders in future studies.

伊朗 20-80 岁健康人群的年龄、性别和侧向分层握力规范及相关社会人口因素：与综合和国际规范的比较

摘要 作为许多不良健康结果的指标，许多人群都建立了握力的规范值。本研究的目的是为伊朗人口建立握力 (HGS) 规范，并将其与其他现有规范进行比较。还确定了影响 HGS 的相关变量，以提供适当的预测模型。样本包括 4282 名伊朗 20-80 岁成年人；分为5年间隔，男性/女性和优势/非优势手。结果与综合数据和其他一些国家的数据进行了比较。为确保数据集有效且具有可比性，按照标准化程序使用 JAMAR® 液压测功机测量 HGS。分别测量手长、掌长、掌宽、前臂长、腕围、前臂围、身高、体重，并计算BMI。为伊朗成年人制定了 HGS 规范。发现倒 U 形寿命曲线，男性（35-39 岁）的平均最大值约为 53 公斤，女性（40-44 岁）为 31 公斤。开发了两个回归模型（手动控制）。伊朗 HGS 的平均值低于综合标准，但高于一些亚洲国家。应用特定于每个人群的规范数据比国际或多国规范更准确。建议在未来的研究中调查伊朗老年人 HGS 与年龄相关的加速下降的原因。开发了两个回归模型（手动控制）。伊朗 HGS 的平均值低于综合标准，但高于一些亚洲国家。应用特定于每个人群的规范数据比国际或多国规范更准确。建议在未来的研究中调查伊朗老年人 HGS 与年龄相关的加速下降的原因。开发了两个回归模型（手动控制）。伊朗 HGS 的平均值低于综合标准，但高于一些亚洲国家。应用特定于每个人群的规范数据比国际或多国规范更准确。建议在未来的研究中调查伊朗老年人 HGS 与年龄相关的加速下降的原因。
