Bone Disorders

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 Health

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...

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
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...

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Changes in the Appendicular Skeleton with Age

Changes in the Appendicular Skeleton with Age

The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
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...

Compact Bone

Compact Bone

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...

Summary

College students in Physical Education (PE) programs have better bone mineral density (BMD) and body composition (BC) than Medical (MED) students. MED students face a significantly higher risk of low bone mass due to lifestyle differences.

Area of Science:

Sports Science
Human Physiology
Biomedical Research

Background:

Understanding the relationship between lifestyle and physiological markers like bone mineral density (BMD) and body composition (BC) is crucial for student health.
Differences in academic focus, such as Medicine (MED) versus Physical Education (PE), may influence lifestyle choices and subsequent health outcomes.

Purpose of the Study:

To compare bone mineral density (BMD) and body composition (BC) between college students in Medicine and Physical Education programs.
To investigate the association between academic discipline, lifestyle, and physiological health indicators.

Main Methods:

A transversal study involving 85 university students (Medicine and Physical Education).
Data collection included anthropometric, socio-demographic, clinical, and lifestyle variables via anamnesis and dual-energy X-ray absorptiometry (DXA).
Statistical analyses employed Student's t-test, Chi-square test, and logistic regression.

Main Results:

Physical Education students exhibited higher lean body mass and lower body fat percentages compared to Medicine students.
Bone mineral density (BMD) at the neck of femur, total femur, and total body was significantly higher in Physical Education students.
Low bone mass was more prevalent in Medicine students, with significantly increased risk across multiple skeletal sites.

Conclusions:

Significant differences in body composition and bone mineral density exist between Medicine and Physical Education students.
Medicine students demonstrate a higher risk for low bone mass, likely linked to lifestyle and physical activity levels.
Physical Education students generally engage in more physical activity, correlating with improved BMD and BC.
