Osteoporosis, a condition where bones become less dense and more prone to fractures, is predominantly seen in the elderly but can also occur in children. Not all fractures in children are due to osteoporosis; some result from high-impact trauma.
Cultivating healthy nutritional and lifestyle habits in childhood is key to preventing osteoporosis and fractures later in life. Achieving a good peak bone mass, which is reached by late twenties, is crucial for long-term bone health.
Factors Affecting Peak Bone Mass
Peak bone mass is influenced by factors, including:
Gender: Generally, men have higher bone mass than women.
Race: African American girls usually achieve higher peak bone mass than Caucasian girls, reducing their risk of osteoporosis. Conversely, Asian girls often have lower bone mass, which increases their risk of osteoporosis.
Hormonal factors: Sex hormones, including oestrogen and testosterone, are essential for bone mass development.
Nutritional status: Calcium and vitamin D are essential for bone health.
Physical activity: Regular physical activity is important for building healthy bones.
Causes of Osteoporosis
In children, osteoporosis is typically secondary to another medical condition or medication used to treat certain conditions. It can also result from genetic disorders such as osteogenesis imperfecta (brittle bone disease). Conditions that increase the risk of osteoporosis can include:
Rheumatological conditions like juvenile arthritis or lupus
Neuromuscular disorders like cerebral palsy, duchenne muscular dystrophy, and immobilisation
Endocrine conditions like hyperthyroidism, hyperparathyroidism, cushing's syndrome, and delayed puberty
Malabsorption syndromes
Anorexia nervosa
Kidney or liver diseases
Certain medications (especially long-term use of corticosteroids or anticonvulsants) and behaviours (prolonged inactivity, inadequate nutrition, and excessive exercise) can also increase osteoporosis risk.
Consult with your child’s doctor if you have concerns about frequent fractures or if your child has a medical condition or is taking medications that could impair bone development.
Diagnosis and Treatment Options for Osteoporosis
Consult a paediatric endocrinologist for an assessment of your child's bone health fracture risk. A bone mineral density scan and blood tests may be performed.
Treatment will vary based on the underlying cause. An example of treatment include the use of bisphosphonate therapy, which can improve bone mineral density in conditions such as osteogenesis imperfecta or steroid-induced osteoporosis.
Tips for Taking Care of Children with Osteoporosis
Ensure your child has a diet rich in calcium and vitamin D
Encourage weight-bearing physical activities like walking, running, dancing and team sports
Limit caffeine and alcohol intake, and discourage smoking
Set a positive example by adopting healthy habits yourself
