This study aimed to classify lower body shapes and examine age-related changes in women aged 20–69, using data from the 8th Size Korea scan. A sample of 450 3D body scans was selected from the 8th Size Korea Survey Database. Using the Grasshopper algorithm from a previous study, 53 measured values were obtained. Principal component analysis identified eight key components: horizontal size, vertical length of the lower body, waist-to-abdomen shape, hip protrusion, abdomen-to-hip shape, abdominal protrusion, thigh-knee-width difference, and thigh slope. Three lower-body types were identified. Type 1 (28%) was the heaviest build, with the shortest lower body length and the most perpendicular body shape from the thigh to the knee when viewed laterally. Type 2 (41.3%) had an average circumference with the flattest belly, and a sloping thigh shape when viewed from the side. Type 3 (30.7%) was the thinnest type, with a notable difference in circumference and position between the waist and belly, a more prominent abdomen and flat buttocks, and the smallest width difference between the thighs and knees. To classify individuals by body type, this study proposes two discriminant functions. Among women in their 20s and 30s, the most prevalent was Type 2; in the 40s, the proportion of Type 3 increased. For those in their 50s and early 60s, Type 2 became more common again, while in the 65+ age group, Type 3 was most frequent.
Abstract
This study aimed to classify lower body shapes and examine age-related changes in women aged 20–69, using data from the 8th Size Korea scan. A sample of 450 3D body scans was selected from the 8th Size Korea Survey Database. Using the Grasshopper algorithm from a previous study, 53 measured values were obtained. Principal component analysis identified eight key components: horizontal size, vertical length of the lower body, waist-to-abdomen shape, hip protrusion, abdomen-to-hip shape, abdominal protrusion, thigh-knee-width difference, and thigh slope. Three lower-body types were identified. Type 1 (28%) was the heaviest build, with the shortest lower body length and the most perpendicular body shape from the thigh to the knee when viewed laterally. Type 2 (41.3%) had an average circumference with the flattest belly, and a sloping thigh shape when viewed from the side. Type 3 (30.7%) was the thinnest type, with a notable difference in circumference and position between the waist and belly, a more prominent abdomen and flat buttocks, and the smallest width difference between the thighs and knees. To classify individuals by body type, this study proposes two discriminant functions. Among women in their 20s and 30s, the most prevalent was Type 2; in the 40s, the proportion of Type 3 increased. For those in their 50s and early 60s, Type 2 became more common again, while in the 65+ age group, Type 3 was most frequent.
