Our hips width continues to increase as we age

Although people do not grow in height after 20 years old of age, our hips width continues to increase as we age. Most people notice that at 40 or 60 years old are much more broad than when they were 20 years and until recently it was believed that this is due to increased body fat.

A survey of the University of North Carolina shows, however, that this increase in pelvis grow with age whether or not people registered an increase of adipose tissue.

Pelvic width of the older participants at the study were, on average, almost 2.5 inches wider than younger patients. This increase of 2.5 cm in pelvis diameter could lead at a widening of the waist by about 7.5 inches between the age of 20 years and 79 years old.

If the rest of the body is growing proportionately, this could cause a significant increase in weight, thus explaining the approximately 500 grams per year that most people accumulate with age.

Orthopedic doctor, Dahners and his colleagues sought to develop this study after they discovered evidence showing increasing hip in patients suffering from bursitis.

Using computer tomography, were gathered information from 246 randomly selected patients, measuring the width and height of L4 vertebral body (indicating whether they were tall or wide delrin), pelvic width strait (birth canal in the middle of the pelvis) distance between the femoral head (hip joint) and femoral head diameters.

Within each age group were about 20 men and 20 women, from age group 20-29 years to the 70-79 years. The results confirmed that the basin width, the width (but not height) of L4 vertebral body, the distance between femoral head and femoral head diameter, all continue to grow after skeletal maturity is reached.

The fact that pelvic strait, has expanded, is an evidence of pelvic growth in all dimensions, rather than a thickening of the bones, say experts.
