The purpose of this study was to measure and compare the hand anthropometric dimensions and strengths of three different occupations. A cross-sectional study was designed to measure 34 hand dimensions and 4 hand strengths of 558 participants consisted of office workers, vehicle mechanics, and farmers. A digital caliper, a hand dynamometer, and a pinch meter were used to collect data. Percentile values for each measurement were tabulated at the 5th, 50th, and 95th percentile levels. The analysis of variance, t test, and Cohen's d were performed to assess the differences in anthropometric variables between groups of workers. The findings demonstrated statistically significant differences in the mean size and strength of the hands across three occupations. Office workers' hands were significantly smaller than those of car mechanics and farmers, particularly in terms of hand depths and widths. Car mechanics' hand circumferences were bigger than those of farmers. Office workers produced the weakest hand strengths. Wrist breadth of workers showed the highest correlation with hand strengths. Compared to other studies, the hands of Iranian workers were wider and thicker, but the length of their hands was similar. Given the significant variances in hand anthropometry between occupational categories, these differences should be incorporated into the design and selection of hand-related products such as gloves and hand tools for each group of workers.

工人的手部人体测量学维度和优势：三种职业的比较

本研究的目的是测量和比较三种不同职业的手部人体测量维度和优势。一项横断面研究旨在测量由办公室工作人员、车辆机械师和农民组成的 558 名参与者的 34 种手部尺寸和 4 种手部力量。使用数字卡尺、手测力计和夹度计来收集数据。每次测量的百分位值在第 5、第 50 和第 95 个百分位水平上制表。方差分析、t检验和 Cohen's d进行评估以评估工人群体之间人体测量变量的差异。研究结果表明，三种职业的手的平均大小和力量存在统计学上的显着差异。上班族的手明显小于汽车修理工和农民，尤其是在手的深度和宽度方面。汽车修理工的手围比农民大。办公室工作人员的手力最弱。工人的手腕宽度与手部力量的相关性最高。与其他研究相比，伊朗工人的手更宽更厚，但他们的手长相似。鉴于职业类别之间手部人体测量学的显着差异，
