Purpose:
Normative values of bone mass, bone turnover markers (BTMs) and muscle-bone unit (MBU) among healthy Asian children are needed to enable accurate skeletal assessment. This cross-sectional study characterizes the bone mineral density (BMD), bone mineral content (BMC), BTMs and MBU of 243 Malaysian preadolescent children aged 9-11 years.
Methods:
The total body BMD (TBBMD), total body BMC (TBBMC), lumbar spine BMD, lumbar spine BMC, and body composition were assessed using dual-energy x-ray absorptiometry. Total and regional MBU were calculated by dividing BMC by lean body mass. Serum BTMs (c-terminal telopeptide 1, procollagen type 1 N propeptide, bone alkaline phosphate, osteocalcin) and serum intact parathyroid hormone were measured.
Results:
Based on the Asian reference population, 97.5% of participants had TBBMD z-scores above -1 standard deviation (SD), 2.5% were at risk for low TBBMD for age (-1.9 to -1.0 SD) and no one had low TBBMD for age (<-2.0 SD). Participants had lower TBBMD values compared to children of the same age according to published data of Asian children despite having higher body weights. There were sex-specific differences in the BTMs and regional MBU of study participants.
Conclusion:
This study provides a population-based dataset on bone mass, BTMs, and MBU of healthy preadolescent Malaysian children, which enables accurate skeletal assessment in this population.

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...

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...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
