Calcium statement from Osteoporosis NZ

Osteoporosis New Zealand is concerned by the nature of the publicity given to early findings of a possible increase in heart attacks among older women taking calcium supplements.

The early results of the study by Auckland University’s bone research group showed an increase in heart attacks. When further analysed the findings were not statistically significant but showed a trend which needs further work for confirmation.

The study of women with an average age of about 70 years, with a total calcium intake of approximately 2,000mg a day, was conducted over 5 years.

However, the study indicates that younger people, in their 50s and 60s, with no history of heart disease are unlikely to be affected and can continue to take their usual calcium supplements.

Dr Liz Spellacy, member of Osteoporosis New Zealand’s Scientific Committee says: “We wish to assure the public that the use of calcium supplements remains appropriate for people who have insufficient calcium in their diet, especially young adults and post-menopausal women.

“Women older than 70 years, particularly if they have a history of heart disease, may wish to discuss reducing their calcium supplement with their GP, say from 1000mg to 500mg depending on their individual circumstances.

“Further research is needed to elucidate the complex relationship between our bones and our circulation. It is important to remember that prevention of osteoporotic fractures also relies on the prevention of falls.”

Debilitating disease

The prevention of osteoporosis begins when people are young -– an active lifestyle and a calcium rich diet are key components in preventing the disease and ensure people achieve peak bone mass by their early 20s.

People concerned about bone health need to look at their lifestyle, exercise regularly where their muscles are working against gravity and improve their intake of calcium through diet. Dairy, tinned fish such as salmon and sardines, spinach and baked beans all contain acceptable levels of calcium.
