Title: Study Finds More Fractures, Less Bone Density In Premenopausal Women With Diabetes

"Study Finds More Fractures, Less Bone Density In Premenopausal Women With Diabetes"

Early Osteoporosis Screening Recommended for Women With Type 1 Second Study Finds Improved Glycemic Control Leads to Better Memory for Men ALEXANDRIA, VA -- January 27, 2006 -- Premenopausal women who have type 1 diabetes should strongly consider preventive screening for osteoporosis, the researchers of a new study on bone density conclude in the February issue of the journal Diabetes Care. The study found that these women exhibited lower bone density and more fractures than women who did not have diabetes, even though those with diabetes were more likely to take bone-active osteoporosis medications and vitamin D supplements. Both groups of women exercised a similar number of hours per week. Researchers found one-third of premenopausal women (ages 35-55) with type 1 diabetes reported having a fracture after age 20, compared to less than a quarter of those who did not have diabetes. Women with type 1 diabetes also exhibited substantially lower bone density in the hip, heel bone and overall. Lead researcher Elsa Strotmeyer, PhD, said it's still unclear why type 1 diabetes affects bone density, however, "it is also likely that even subclinical changes in the cardiovascular system, kidney or nervous system, which are often associated with a longer duration of disease, are influencing bone," she said. The researchers, from the University of Pittsburgh's Department of Epidemiology in the Graduate School of Public Health and Department of Health Promotion and Development in the School of Nursing, concluded that early osteoporosis screening and fracture prevention efforts should be considered for women with type 1 diabetes prior to menopause. Improved Glucose Control Can Improve Memory Taking medication to control blood glucose (sugar) levels can also improve your memory, according to another study in the February issue of Diabetes Care. Older adults with type 2 diabetes often have difficulty with their memories. To determine whether different types of medication would improve learning and memory, 145 adults with type 2 diabetes who were already taking the oral medication metformin were randomly assigned to additional treatment with either rosiglitazone (which improves insulin sensitivity) or glyburide (which promotes insulin production). Subjects were followed over a six-month period and completed a series of learning and memory tests at the beginning and end of the study. The research team found that both rosiglitazone and glyburide improved fasting plasma glucose values an average of 21-24%, and both produced equivalent improvements on a cognitively demanding measure of working memory (25-31% reduction in errors). The strong relationship between improved fasting blood glucose and memory scores indicates that efforts to reduce blood glucose levels may substantially improve memory in many older adults with diabetes. The authors conclude that further testing is necessary to determine whether these effects are long-lasting and also whether greater benefit would be seen in people with more severe diabetes and greater cognitive impairment.
