Do Japanese have a different pelvis position than Europeans? I was watching a show that made the claim that European women's pelvis is tilted more forward compared to Japanese women's which places their butts higher up. Is this information accurate?

According to this study there are significant pelvic position differences between Caucasian and Asian populations. However the biggest difference is lumbar lordosis (the curve at the small of the back) where Caucasians have almost 10 degrees more curve. The study doesn't explicitly say it but that would suggest Caucasians butts are higher.
