Fear of hypoglycemia a barrier to exercise for type 1 diabetics
People are different, both physically and mentally, but genetically everyone is very similar. That’s been the thought of scientists for decades now. But with population research becoming more and more common, the University of Alberta’s Tim Caulfield is concerned that genetic research could awaken racist attitudes. Just last year Nobel Prize winning geneticist James Watson

According to a new study, published in the November issue of Diabetes Care , a majority of diabetics avoid physical activity because they worry about exercise-induced hypoglycemia (low blood sugar) and severe consequences including loss of consciousness.
Despite the well-known benefits of exercise, this new study builds on previous investigations that found more than 60 percent of adult diabetics aren’t physically active.
“Our findings confirmed our clinical suspicion,” say Dr. Rémi Rabasa-Lhoret, co-author of the study, a professor at the Université de Montréal’s Faculty of Medicine and an endocrinologist at the Centre hospitalier de l’Université de Montréal (CHUM). “Exercise has been proven to improve health and one would assume diabetics would remain active. Yet our findings indicate that type 1 diabetics, much like the general public, are not completely comfortable with exercise.”
Lack of understanding of insulin metabolism
One hundred adults, 50 women and 50 men, with type 1 diabetes answered questionnaires to assess their barriers to physical activity. The biggest fear was hypoglycaemia and other barriers included interference with work schedule, loss of control over diabetes and low levels of fitness.
When questioned further, only 52 of the participants demonstrated appropriate knowledge of how insulin is metabolized and processed. Those individuals who best understood how insulin works in their body were shown to be less fearful of physical activity. Such knowledge is essential in order to adapt insulin and/or food intake to prevent hypoglycaemia induced by exercise.
“Our study was launched to find ways to make diabetics healthier and suggests there is a major gap in information and support required by these patients,” says Anne-Sophie Brazeau, lead author and doctoral student at the Université de Montréal. “Programs aimed an increasing physical activity among type 1 adult diabetics need to incorporate specific actions to prevent hypoglycemia.”
“We also found that individuals with the greatest fear of physical activity had the poorest control of their diabetes,” says Dr. Hortensia Mircescu, co-author of the study, a professor at the Université de Montréal’s Faculty of Medicine and a CHUM endocrinologist. “Education is particularly relevant for this group.”
Researchers from Boston University’s Slone Epidemiology Center have found that reducing time spent watching television and increasing time spent walking briskly or engaged in vigorous physical activity may reduce the incidence of type 2 diabetes in African-American women. These findings appear on-line in the American Journal of Epidemiology. Type 2 diabetes has reached epidemic proportions

Canadian researchers have identified a new protein in the progression of breast cancer. According to a recent study from the Université de Montréal and the University of Alberta, published in the Journal of Biological Chemistry, the protein ARF1 plays a critical role in cancer cell growth and the spread of tumours. Targeting this protein with

Suffering from end-stage renal disease (ESRD), a growing number of patients at the Centre hospitalier de l’Université de Montréal (CHUM), have become the beneficiaries of a North American breakthrough: high efficacy hemodiafiltration (HDF). An extracorporeal blood purification technique, HDF is indicated for ESRD patients. Since the HDF unit was introduced in CHUM’s Nephrology section, preliminary

A study in the Dec. 15 issue of the Journal of Clinical Sleep Medicine suggests that screening type 2 diabetes patients for obstructive sleep apnea (OSA) and treating those who have OSA with continuous positive airway pressure (CPAP) therapy could improve the management of their hyperglycemia and might favorably influence their long-term prognosis. Results

Several studies had previously suggested that regular physical exercise reduces the breast cancer risk of women. However, it had been unknowned just how much exercise women should take in which period in life in order to benefit from this protective effect. Moreover, little was known about which particular type of breast cancer is influenced by
