Abstract:
The present study initially included 106 volunteers, elderly women living in urban or suburban Khon Kaen, Thailand. One case was excluded because of extremely high levels of alkaline phosphatase. The means (+/- SD) of the serum calcidiol and the PTH concentrations in the urban vs suburban groups were 31.45(+/- 1.15) ng/mL vs 36.15(+/- 2.4) pg/mL and 41.53(+/- 3.94) ng/mL vs 17.43(+/- 2.88)pg/mL, respectively. The urban group had a higher percentage and a higher risk of hypovitaminosis D and osteoporosis of the femoral neck than the suburban group, an odds ratio of more than 4 times higher.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
