Strength of Bone May Be Related to Late Puberty

Strength of Bone May Be Related to Late Puberty


According to a study, the strength of bone is linked to the puberty timing. The study included over 6,000 Bristol’s children between the age of 10 to 25. The researchers focused on the bone scans of the children in order to check whether the puberty time has any influence over the bone density throughout the developing of a child into an adult. They found that the kids who experienced their growth spurts late than the age of puberty had a lower bone density in its adulthood for several years. According to Ahmed Elhakeem, an epidemiologist at the University of Bristol and the lead author of the study said that later maturing teens have lower bone strength than average while adolescence. This may also increase the risk of fracture and osteoporosis later in the future. For instance, simulations of bone remodeling showed an increase of 10% in bone mineral density which can delay osteoporosis by 13 years.

In a study, the researchers turned to the Avon Longitudinal Study of Parents and Children (ALSPAC) where all pregnant women were recruited to take a closer look. The women were residing in southwest England which was served by three National Health Service authorities. The pregnant women were expected to give birth between April 1991 to December 1992. The researchers focused on babies born during this period. They measured the height of the kids between the ages of 5 and 20, followed by one measurement after age 9. All children were invited to measure bone density at age of 10, 12, 14, 16, 18, and 25. In order to correlate the growth spurt age with bone density, the researchers analyzed on the basis of various factors including birth weight, body mass index (BMI), socioeconomic status, and early life diet.

The growth spurts of girls were on average at age of 11.5, while the boys spurted at an average age of 13.5. The girls gained bone mineral density at a lower rate than boys. According to researchers, the maximum gain in bone density took place between a year prior to the growth spurt and after two years. The author further advises the kids experiencing a late growth spurt to follow the Royal Osteoporosis Society recommendations. It provides advice to include plenty of exercise and a healthy lifestyle in order to strengthen their bones.
