Pelvic shape of contemporary young women:Related factors and impact on daily life

Being safe and simple, external pelvimetry is also known for its usefulness in current developments in medical technologies. However, its standard measurement values have been used for more than 40 years, since the 1970s.This study therefore aimed to provide for a better understanding of changes in its standard measurement values by external pelvimetry and how pelvic shape is related to genetic factors, dieting for weight loss, and exercise experience. In addition, this study aimed to elucidate the relationship between pelvic size and balance, the daily discomforts frequently reported by women in early maturity, and to provide data leading to improved care that can contribute to a higher quality of life among women. Our results showed that contemporary women in early maturity have significant development in the intertrochanteric diameter of the pelvis, but no major change in other diameter lines. Development of the intertrochanteric diameter was associated with a higher intertrochanteric diameter-toexternal conjugate ratio, but overall, no significant change was noted in pelvic balance. Pelvic size and balance were only slightly influenced by physique at birth and genetic factors, however current body fat percentage was of significant relevance. Of women with discomfort in daily life, those who had leg swelling, stiff neck, urinary incontinence, or abdominal bloating had larger pelvises, especially in the transverse direction, than women who did not have these symptoms. These findings revealed that in women with pelvic pain and fatigability, only the external conjugate is enlarged.
