Women with Osteoporosis and Low Bone Density Are at Increased Risk of Hearing Loss

Hearing loss is the third most common chronic health condition in the United States. Previous studies of people with hearing loss have uncovered higher prevalence of osteoporosis — a disease in which the bones become weak and brittle — and low bone density (LBD). But research on whether these conditions may influence risk of hearing loss over time is scarce. It is also unknown whether hearing loss can be avoided by taking bisphosphonates, the primary medication used to prevent fractures in people with reduced bone density. As part of the Conservation of Hearing Study (CHEARS), researchers from Brigham and Women’s Hospital analyzed data from nearly 144,000 women who were followed for up to 34 years. They found that risk of subsequent moderate or worse hearing loss was up to 40 percent higher in study participants with osteoporosis or LBD. The study, published in the Journal of the American Geriatrics Society, also found that bisphosphonates did not alter risk of hearing loss.

Thin and brittle bones strongly linked to women’s heart disease risk

Thinning lower spine, top of thigh bone and hip predictive of raised heart attack/stroke risk

Thin and brittle bones are strongly linked to women’s heart disease risk, with thinning of the lower (lumbar) spine, top of the thigh bone (femoral neck), and hip especially predictive of a heightened heart attack and stroke risk, suggests research in the journal Heart.

Osteoporosis, often dubbed brittle bone disease, is common, particularly among women after the menopause. It is characterised by thinning and weakened bones and a heightened fracture risk.

Stronger bones thanks to heat and microbiota

Osteoporosis, a bone disease linked to ageing, is characterised by a loss of bone density, micro-architectural deterioration of the bones and an increased risk of fractures. With one third of postmenopausal women affected, it is a major public health problem. Through epidemiological analyses, laboratory experiments and state-of-the-art metagenomic and metabolomics tools, a research team has observed that exposure to warmer ambient temperatures (34 °C) increases bone strength, while preventing the loss of bone density typical of osteoporosis. Moreover, this phenomenon, linked to a change in the composition of gut microbiota triggered by heat, could be replicated by transplanting the microbiota of mice living in a warm environment to mice suffering from osteoporosis. Indeed, after the transplant, their bones were stronger and denser. These results, to be discovered in Cell Metabolism, make it possible to imagine effective and innovative interventions for prevention and treatment of osteoporosis.

Too much Vitamin A & Bone Health

New research in mice demonstrates the risk to decrease bone thickness and increase bone fractures with consuming too much vitamin A (Journal of Endocrinology). Experts at Society for Endocrinology warned people against over-supplementing vitamin A in their diets.
