Insights

Children with developmental coordination disorder (DCD) show lower bone mineralization. Engaging in diverse activities, not just physical ones, is crucial for improving bone health in these children.

Area of Science:

  • Pediatric Health
  • Bone Metabolism
  • Developmental Disorders

Background:

  • Children with developmental coordination disorder (DCD) often exhibit limited participation in various activities.
  • This limited engagement may negatively impact bone mineral accrual and overall bone health.

Purpose of the Study:

  • To compare bone mineralization and activity participation in children with DCD versus typically developing peers.
  • To determine the association between activity participation patterns and bone mineralization in children with DCD.

Main Methods:

  • Evaluated bone mineral content (BMC) and bone mineral density (BMD) using dual-energy X-ray absorptiometry in 52 children with DCD and 61 controls.
  • Assessed activity participation patterns using the Children's Assessment of Participation and Enjoyment (CAPE) questionnaire.

Main Results:

  • Children with DCD had significantly lower BMC and BMD compared to controls.
  • Lower total activity and physical activity diversity scores were observed in children with DCD.
  • Total activity diversity independently predicted leg BMC in children with DCD, accounting for 5.1% of variance.

Conclusions:

  • Pre-pubertal children with DCD demonstrate reduced diversity in activity participation and lower bone mineralization.
  • Limited diversity in overall activity participation is a contributing factor to lower bone mineral content in the legs of children with DCD.

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
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...

Essential Minerals for Bone Health01:31

Essential Minerals for Bone Health

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a...

Bones of the Lower Limb: Tibia and Fibula01:10

Bones of the Lower Limb: Tibia and Fibula

The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...
