Bone Disorders01:29

Bone Disorders

8.1K
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

7.2K
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...

Compact Bone01:27

Compact Bone

21.8K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Bone Structure01:55

Bone Structure

53.1K
Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

6.0K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Classification of Bones01:18

Classification of Bones

14.1K
The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The...

Area of Science:

  • Public Health
  • Epidemiology
  • Bone Health Research

Background:

  • Osteoporosis is a growing global health concern requiring effective prevention strategies.
  • Targeting at-risk individuals is a key approach for managing osteoporosis, especially with limited resources.
  • The Iranian Multicenter Osteoporosis Study (IMOS) program assesses bone health and vitamin D status nationwide.

Purpose of the Study:

  • To present the refined protocol for the third phase of the IMOS study.
  • To improve upon previous phases by addressing subject loss and enhancing data collection.
  • To provide a comprehensive framework for studying osteoporosis and related factors.

Main Methods:

  • The study protocol was developed based on extensive literature review of osteoporosis risk factors and secondary causes.
  • An expert panel approved the study questionnaire, ensuring scientific rigor.
  • The protocol incorporates lessons learned from prior study phases to optimize methodology.

Main Results:

  • The protocol provides a versatile framework for investigating various osteoporosis-related issues.
  • It offers valuable data for policymakers and researchers beyond a single-aspect study.
  • The methodology is designed to yield generalizable results for national health planning.

Conclusions:

  • The protocol can be adapted for use in developing countries to gather crucial national bone health data.
  • It empowers policymakers with accurate information for evidence-based decision-making.
  • The study contributes to a better understanding and management of osteoporosis globally.
