Objective To explore the normal values of aesthetic standards of upper limbs in unmarried young women in Central Plains, to provide reference and basis for upper limb cosmetic surgery and to accumulate information for human morphology. Methods Height, body mass, upper limb length, full arm length, upper arm length, axillary-radial stem distance, elbow transverse distance at the thickest point of the upper arm, elbow transverse distance at the thickest point of the forearm, upper limb root circumference, upper arm circumference at the axillary area, upper arm minimum circumference, elbow circumference, forearm maximum circumference, forearm minimum circumference, etc. were measured in 603 healthy unmarried young women, and the mean and standard deviation of each measurement value were calculated, and the relevant indexes were analyzed by SPSS15. 0 statistical software was used for correlation analysis. Results Height (163.3648±4.3382)M, body mass (55.3232±21.7951)K, upper limb length (70.7197±2.8534)M, full arm length (52.7545±2.2544)M, upper arm length (30.2470±1.4987)M, axillary-radial stem distance (20.3266± 1.2353)M, elbow transverse distance at the thickest point of the upper arm (5.9021±1.2330)M, elbow transverse distance at the thickest point of the forearm (12.6699±1. 0192)M, upper limb root circumference (36.9187±2.5863)M, upper arm circumference at the axillary area (27.3515±1.2717)M, upper arm circumference (24.2603±8.3830)M M, upper arm minimum circumference (21.3880±1.5759)M, elbow circumference (21. 3466±1.4967)M, forearm maximum circumference (21.6666±1.3118)M, forearm minimum circumference (14.8225±0.9222)M, upper limb standard index (43.29±0.0123)%, upper limb-upper arm length index (42.77±0. 0146)%, forearm circumference index (68.50±0.0374)%, upper arm thickest point elbow transverse distance/axillary stem distance/% (62.37±0.0407)%, axillary upper arm circumference/upper limb root circumference/% (72.62±0.0984)%, upper arm minimum circumference/upper arm circumference/% (89.50±0. 062)%; upper arm length, full arm length, upper arm length, upper arm axillary-radial stem distance, upper arm thickest point elbow transverse distance, upper limb root circumference, upper arm minimum circumference, elbow circumference, forearm maximum circumference, forearm minimum circumference, upper limb-. The upper arm length index was related to both height and body mass; the upper arm thickest point elbow transverse distance/axillary stem distance, upper arm minimum circumference/upper arm circumference, and forearm circumference index were not related to either height or body mass; the forearm thickest point elbow transverse distance was related to height and not to body mass; the upper arm circumference at the axillary site, upper arm circumference, and upper arm circumference at the axillary site/upper arm root circumference were not related to height and were related to body mass; the upper limb standard index was related to body mass The upper limb standard index was related to body mass. Conclusion The measured values provide aesthetic measurements for the analysis of human characteristics and upper limb aesthetic surgery for young women in the Central Plains. Young unmarried women; upper limbs; measurement of upper limb length and related factual analysis in young unmarried women in the Central Region Lili Guo, Minjing Chen, Linbo Liu Department of Plastic Surgery, The First Affiliated Hospital of Zhengzhou University. Abstract: Objective To study the aesthetic criteria of upper limb length in young unmarried females to provide additional reference for upper limb plastic surgery. Methods Based on data from 603 young healthy females aged 17-24 years, the mean and standard of height, weight, upper limb length, total arm length, upper arm length, axillary to wrist distance, sickle circumference, axillary arm circumference, biceps circumference, minimum biceps circumference, elbow circumference, maximum forearm circumference, and minimum forearm circumference were calculated. Correlations between these parameters were analyzed with SPSS 15.0 software. Results Height (163.3648±4.3382) cm, weight (55.3232±21.7951) kg, upper limb length (70.7197±2.8534) cm, total arm length (52.7545±2.2544) cm, upper arm length (30.2470±1.4987) cm, axillary to wrist distance (20.3266 ±1. 2353) cm, sickle circumference (36.9187 ±2.5863) cm, axillary arm circumference (27.3515 ±1.2717) cm, elbow circumference (21.3466 ±1.4967) cm, biceps circumference (24.2603 ±8.3830) cm, minimum biceps circumference (21.3880 ±1.5759) cm, maximum forearm circumference was (21. 6666±1.3118) cm, minimum forearm circumference was (14.8225±0.9222) cm, upper limb length to height ratio was (43.29±0.0123) %, upper arm length to upper limb length ratio was (42.77±0.0146) %, minimum biceps circumference to biceps circumference ratio was (89. 50±0.062) %, forearm circumference index was (68.50±0.0374)%, the distance ratio from the point of maximum biceps circumference to the elbow was (5.9021±1.2330) cm, and the distance from the point of maximum forearm circumference to the elbow was (12.6699±1.0192) cm. upper limb length, upper arm length, total arm length, axillary to wrist distance, sickle circumference, minimum biceps circumference, elbow circumference, the maximum forearm circumference, and minimum forearm circumference were significantly correlated with height and weight. Axillary arm circumference and biceps circumference were significantly correlated with body weight, but not with height. Forearm circumference index had no significant correlation with height and weight. Conclusion This paper is a useful reference for analyzing the characteristics of human body and upper limb cosmetology. Keywords Unmarried women, upper limbs, measurements References 1.
