Overview

As we progress through adulthood, bone resorption occurs at a rate faster than bone formation. This results in a gradual fail in bone mass as we age.

Rickets and Osteomalacia

Rickets is a condition that results from a delay in deposition of bone mineral (especially calcium and phosphate) for bone growth. This is a result of poor vitamin D, and is characterised by skeletal deformities such as bowed legs.

Osteoporosis

Excessive loss of bone tissue leads to osteoporosis, a condition that is characterised by bone fragility and increased risk of bone fracture. Osteoporosis may lead to mobility problems and even death.

Factors affecting bone strength

  • Oestrogen
  • Physical Activity
  • Diet

Oestrogen

Plays an important role in women to protect bones. Thus, irregular or loss of menstrual periods can be detrimental to bones because after menopause, oestrogen is no longer produced, which eventually causing increased bone loss compared to men of same age.

Physical activity

Especially weight bearing activity, is of critical importance in building and maintaining strong bones. Engaging with regular physical activity has many benefits for people of all ages. Being overweight can be associated with osteoarthritis. Therefore, weight loss and regular physical activity can relieve symptoms.

Diet

Important in both childhood development of strong bones and in adulthood maintenance of the bones. A number of nutrients are required but is is a lack of vitamin D in particular that is associated with rickets in children. Diet and nutrient status are important factors in formation of healthy bones, particularly calcium, vitamin.

Calcium + Vitamin D

Calcium intake is particularly important during childhood, adolescence and adulthood for bones development. Vitamin D assists in the absorption of calcium from food. Some vitamin D is acquired from the diet but for most people the major source is through synthesis in skin that is exposed to sunlight.
