With aging, the feet of the elderly above 60 years old in China present degenerative changes, deformities, and diseases, which significantly affect their daily activities.
The authors aimed to study the morphological characteristics of the feet and identify the foot type according to size (length and width) and defect characteristics of elderly feet in China.
A convenient sample of 1000 subjects above 60 years old was recruited mainly in the regions of Shanghai, Shaanxi, Henan, Hebei, and Sichuan in China. Foot images were collected, and 800 (male 398, female 402) valid questionnaires were recovered. A total of 800 elderly subjects as the test group were invited to measure their foot sizes by means of a Footprint Collector (Tong Yuan Tang Health Management Limited, Qingdao in Shandong province). The foot type of the elderly was compared with that of the general adult Chinese population as the control group using the t-test for independent samples.
Hallux valgus (46.9%) and flat foot (50.0%) were the most common foot shape deformities. The most frequent foot diseases were foot scaling (91.2%) and calluses (96.3%). The medial width of the first metatarsal-toe joint of the elderly was significantly higher (elderly female, 44.95±4.86mm; elderly male, 48.55±4.94mm) than that of the general adult population (adult female, 40.18±3.43mm; adult male, 43.22±3.20mm) (p<0.01).
The foot length of the elderly was not significantly different from that of the general adult Chinese population. The width of the first metatarsal-toe joint in the forefoot of the elderly was significantly higher than that of the general adult Chinese population, which was consistent with the result that a high proportion of elderly subjects presented hallux valgus.
随着年龄增长，中国60岁以上老年人的足部出现退行性变化、畸形和疾病，这显著影响他们的日常活动。
作者旨在研究老年人足部的形态特征，并根据中国老年人足部的尺寸（长度和宽度）及缺陷特征确定足型。
主要在中国上海、陕西、河南、河北和四川等地招募了1000名60岁以上的便利样本。收集足部图像，回收了800份（男性398份，女性402份）有效问卷。共邀请800名老年受试者作为测试组，通过脚印采集器（山东青岛通元堂健康管理有限公司）测量他们的足部尺寸。使用独立样本t检验将老年人的足型与作为对照组的中国普通成年人群的足型进行比较。
拇外翻（46.9%）和平足（50.0%）是最常见的足部畸形。最常见的足部疾病是足部鳞屑（91.2%）和胼胝（96.3%）。老年人第一跖趾关节的内侧宽度显著高于普通成年人群（老年女性，44.95±4.86mm；老年男性，48.55±4.94mm）（成年女性，40.18±3.43mm；成年男性，43.22±3.20mm）（p<0.01）。
老年人的足长与中国普通成年人群没有显著差异。老年人前足第一跖趾关节的宽度显著高于中国普通成年人群，这与高比例老年受试者出现拇外翻的结果一致。
