시대 변화에 따른 20~30대 키 큰 남성의 체형 특성 변화 연구 - 제6차, 제8차 Size Korea 인체 측정 데이터를 기반으로 -

초록

This study analyzes body shape changes over time among tall men in their 20s and 30s to provide foundational data for establishing an appropriate sizing system. Subjects included men aged 20－39 in the top 25% by height: 437 from the 6th Korean anthropometric survey and 279 from the 8th. Additionally, 62 items, including 60 direct measurements and 2 index items, were analyzed using descriptive statistics and an independent samples t-test. First, body shape changes by measurement year showed statistically significant differences in most items. Stature increased significantly, with shifts in upward waist and downward hip positions, indicating altered proportions. Shoulder measurements increased significantly, while chest, waist, and hip circumferences showed greater increases than other measurements. All breadth and depth measurements increased, indicating expanded horizontal dimensions. Weight and BMI reached obesity classification in the 8th survey, confirming body size increase and obesity trends. Second, analysis by measurement year and age group revealed both groups had similar increases in stature and shoulder measurements. Men in their 30s exhibited a greater increase in waist height and a smaller increase in hip height, along with more noticeable proportional changes. They also experienced significantly larger increases in chest, waist, and hip circumferences, which are important for pattern design, and displayed stronger tendencies toward obesity. Third, two-way analysis of variance revealed significant interactions for horizontal dimensions and obesity indices, indicating age-specific temporal changes. These findings necessitate a new sizing system reflecting age-specific body shape changes for tall men in their 20s and 30s.
