Synopsis
A groundbreaking study reveals that older women can safely use calcium supplements without fear of increasing dementia risk. This research dispels previous concerns and reassures patients and doctors alike. Discover the findings that could change how we view calcium's role in women's health today!
Key Takeaways
- No link found between calcium supplements and increased dementia risk in older women.
- Calcium is crucial for bone health.
- Study involved 1,460 women over five years.
- Findings published in The Lancet.
- Further research is required to explore effects on other demographics.
New Delhi, Oct 7 (NationPress) Researchers from Australia have concluded that there is no substantial proof indicating that calcium monotherapy leads to an increased long-term risk of dementia, especially among older women.
Calcium supplements are vital for various physiological functions, notably in enhancing bone health.
The investigation, spearheaded by a coalition from Edith Cowan University (ECU), Curtin University, and the University of Western Australia, alleviated previous worries about the possible adverse effects of calcium supplements on cognitive health in older females.
The research utilized data from earlier studies involving 1,460 older women who received either calcium supplements or a placebo over five years. Findings published in The Lancet Regional Health-Western Pacific revealed no significant increase in the long-term risk of dementia attributable to the supplements.
“Calcium supplements are frequently suggested for the prevention or management of osteoporosis,” remarked Negar Ghasemifard, a doctoral candidate at ECU.
“The outcomes of our study offer reassurance to both patients and healthcare professionals regarding the safety of calcium supplements concerning dementia risks in older women,” Ghasemifard expressed.
Approximately 20% of women over 70 are impacted by osteoporosis, making calcium supplementation a widely endorsed preventive strategy against fractures.
While these findings may help dispel worries about the link between calcium supplementation and overall dementia risk in older women, particularly those over 80, additional research is necessary, according to the team.
“It remains uncertain whether these results apply to other demographics, such as men or women starting supplementation earlier in life,” stated Professor Simon Laws, who leads ECU's Center for Precision Health.
Laws emphasized the necessity for clinical trials assessing calcium supplements, with or without vitamin D, to validate these findings, particularly concerning brain health, and to fill existing research gaps. These trials should prioritize specific and comprehensive evaluations of brain health as the main outcome, he noted.
Point of View
I find this research provides a reassuring perspective on calcium supplementation for older women. While the findings are promising, we must remain vigilant and advocate for ongoing research to ensure the health and safety of our aging population.
