I just read an article published in ScienceDaily (Nov. 30, 2010) that says that belly fat in women can cause a decrease in bone strength and an increase in osteoporosis.
In the past, studies had indicated that the opposite was true, stating that the excess body fat protected against bone loss. But a new study presented at the annual meeting of the Radiological Society of North America (RSNA) found that having too much internal abdominal fat may have a big impact on bone health.
"We know that obesity is a major public health problem," said the study's lead author, Miriam A. Bredella, M.D., a radiologist at Massachusetts General Hospital and assistant professor of radiology at Harvard Medical School in Boston. "Now we know that abdominal obesity needs to be included as a risk factor for osteoporosis and bone loss."
We already know that approximately 72 million American adults are considered obese (according to the Centers for Disease Control and Prevention). Obesity is defined as having a body mass index (BMI) of 30 or more and that being obese contributes to a multitude of health problems.
When it comes to being overweight, or obese, the type of fat stored by the body is what determines what type of issue the body may experience. We have many types of fat; subcutaneous, superficial, even bone marrow fat, but visceral fat--the intra-abdominal fat that is packed around the organs in the abdominal cavity---is the fat that is associated with an increased risk of heart disease.
In his study, Dr. Bredella and his colleagues set out to evaluate the abdominal subcutaneous, visceral and total fat, as well as bone marrow fat and bone mineral density, in 50 premenopausal women with a mean BMI of 30. Each woman's bone density was tested using specialized equipment. The imaging revealed that women with more visceral fat had increased bone marrow fat and decreased bone mineral density.
Dr. Bredella concluded, "Our results showed that having a lot of belly fat is more detrimental to bone health than having more superficial fat or fat around the hips. It is important for the public to be aware that excess belly fat is a risk factor for bone loss, as well as heart disease and diabetes."
While bone loss is more common in women, the research team is currently conducting a study to determine whether belly fat is also a risk factor for bone loss in men. According to the National Women's Health Information Center, 10 million Americans have osteoporosis and 18 million more have low bone mass, placing them at risk for the disease.
Osteoporosis, or low bone mass, is a disease that puts you at risk for bone fractures. It also is the reason that older people, mostly women, stoop over when they are upright. The name Osteoporosis literally means "porous bones." Most common in post-menopausal women, after age 75 it is seen in both men and women.
Exercise and taking the proper amount of calcium and Vitamin D have been shown to greatly reduce the chances of developing the disease, or helping minimize it once it has been diagnosed.
The lesson here is pretty obvious: get off the couch, exercise and lose some weight. Your entire body will thank you for it!
