시니어 여성의 인체치수 변화 및 체형 유형 분석: Size Korea 3D 인체 측정 데이터를 기반으로

This study aimed to scientifically identify the physical characteristics of senior women in an aging society by analyzing body measurement changes and body type classification of senior women over approximately 8 years based on Size Korea 3D body measurement data. Independent sample t-tests were conducted on 54 anthropometric items from 686 senior women aged 70～84 years from the 6th (2014) and 8th (2022) surveys. Results showed that while height and upper body-related measurements increased, lower body-related heights such as hip height and knee height decreased, indicating a relative increase in upper body length. For circumference measurements, major areas such as abdominal and thigh circumferences increased, while narrower areas of the upper and lower extremities including waist, armpit, calf, and ankle circumferences showed a decreasing trend. Width measurements generally increased, but hip thickness decreased, confirming different change patterns by body parts where the body became wider laterally but thinner anteroposteriorly in the hip area. Based on K-means cluster analysis using five factors derived from factor analysis (upper body horizontal size, vertical size, lower body horizontal size, shoulder size, and torso length), three body types were classified: small slim type (30.9%), large physique type (16.6%), and medium upper body obesity type (52.5%). Three-dimensional visualization using Size Korea 3D body shape data specifically presented the morphological characteristics of each body type. The results of this study are expected to be utilized as foundational data for various industry sectors related to seniors in a super-aged society.
