Bone density refers to the amount of bone tissue contained in the bones of the human body. Body weight, physical activity, hormones and calcium intake have been said to be the variables affecting bone density. A reduced bone density can lead to osteoporosis which is described as the thinning of the bones due to lack of calcium and bone protein. These essential elements are needed to produce healthy and strong bones. The bone density of adults is the product of the peak bone density reached during adolescence.
The adolescent years are critical for the development of bones and achievement of high bone density. Among the variables mentioned, they have a positive correlation with bone density which signifies the importance of developing strong bones beginning childhood and adolescence. Body weight has a significant and positive correlation with bone density. Studies in epidemiology have shown that high body weight or a high body mass index will lead to reduction in bone density.
Consequently, a low body weight will result in a higher bone density. Calcium intake and physical activity also have a positive correlation with bone density. Milk is an excellent source of calcium. Adolescents who consume more glasses of milk everyday have been found to have experienced an increase in bone density. Increased activity levels also contribute to a higher bone density in adults because it promotes the development of strong bones. Exercising is good for the body particularly the bones. Hormones also affect bone density.
Women have hormones called estrogen while the men have testosterone. An low level of estrogen in teenage girls will lead to a lower bone density. The development of healthy and strong bones is important during the period of adolescence because it significantly contributes to a higher bone density. Moreover, an increase in bone density will reduce the risk the development of osteoporosis later on in life. The factors affecting bone density help determine how they can have a positive or negative impact on the human body.
