During pregnancy calcium and Vitamin D support the mineralisation of the developing baby’s bones and the continued skeletal growth in the infant.
- The vast majority of adult bone mass is attained before the age of 14.
- 95% of the adult skeleton is formed by the end of adolescence.
- Childhood and adolescence are times of rapid growth and critical periods for building bone mass.
Peak bone mass generally occurs between the age 20 – 301.
From our mid-30’s, bone loss slowly begins.
All through your life, your body is continually removing old bone and replacing it with fresh bone. This process is called remodelling. After age 40, less bone is replaced.
- From Menopause, bone loss occurs at a much quicker rate due to the rapid decline in oestrogen levels. If a woman’s peak bone mass before menopause is less than ideal, any bone loss that occurs during menopause may result in osteoporosis.
- For about the first 5 years after menopause, women lose bone at the rate of about 2%–3% per year and then continue to lose about 1% of bone mass per year to the end of life.
- Men start to lose bone at about the age of 50 years, but more slowly than women.
- 66% of people over 50 have Osteoporosis or poor bone health.
- The rate of bone loss in men and women over the age of 60 years is about the same, and calcium absorption decreases with age.
