Calcium supplements fail to prevent bone fractures in children
September 15, 2006
Effects of calcium supplementation on bone density in healthy children: Meta-analysis of randomised controlled trials Calcium supplements have very little benefit for preventing fractures in childhood and later adulthood, concludes a study in the BMJ.
Children taking such supplements are have only small improvements in bone density, which are unlikely to reduce fracture risk, says the study carried out by researchers at the Menzies Research Institute in Australia and other approaches could be more beneficial such as increasing vitamin D concentrations and eating more fruit and vegetables.
Osteoporosis is a major public health problem, particularly in women, and low bone mineral density is an important risk factor for osteoporotic fractures. Bone density worsens for women after the menopause, so intervention in childhood to maximise peak bone mass by improving factors such as diet and physical activity can minimise the impact of bone loss related to age.
The researchers analysed the findings of 19 different studies involving 2,859 children collectively aged between three and 18. They included randomised trials of calcium supplementation in healthy children that lasted at least three months and which measured bone outcomes after at least six months of follow-up.
They found there was a small effect on total body bone mineral content and upper limb bone mineral density - children taking the supplements only had 1.7% better bone density in their upper limbs than children not taking the supplements.
However, there was no effect at important sites in the body for fracture in later life - namely the hip and lumbar spine. After children stopped taking calcium supplements, the effect persisted at the upper limb, but disappeared for total body bone mineral content.
The authors conclude: "The small effect of calcium supplementation on bone mineral density in the upper limb is unlikely to reduce the risk of fracture, either in childhood or later life, to a degree of major public health importance. It may be appropriate to explore alternative nutritional interventions, such as increasing vitamin D concentrations and intake of fruit and vegetables."

Schiff Super Calcium 1200 mg with Vitamin D, 120 Softgels

Calcium is an essential mineral in the maintenance of strong bones and teeth. Regular exercise and a healthy diet with enough calcium helps teen and young adult Caucasian and Asian women maintain good bone health and may reduce their high risk of osteoporosis later in life. Adequate calcium intake is important, but daily intakes above about 2,000 mg are not likely to provide any additional benefits. Vitamin D regulates the absorption of calcium and phosphorus and helps form tooth and bone. (These statements have not been evaluated by the Food and Drug Administration.
