NEW TECHNOLOGY. The insulin pump is one piece of technology that has improved diabetes treatment and research. The pump both automatically administers insulin and measures blood sugar levels.
With obesity on the rise in Canada, the rate of diabetes has risen rapidly in the last several decades. The correlation is so strong that doctors and medical researchers have taken to using the term “diabesity” to describe a condition in which a patient has one because of the other. “The two go hand in hand— obesity begets diabetes,” Stewart Harris, a professor at the Schulich School of Medicine and Dentistry, explained. “If you want to eliminate the diabetes problem, you’ve got to tackle obesity.” That is exactly what Harris is aiming to do with his new program, Healthy Moms, Healthy Babies, that aims to promote healthy lifestyles in pregnant women, with a particular emphasis on First Nations women. According to Harris, pregnant women are particularly vulnerable to diabetes, none more so than those in the First Nations population. First Nations populations are particularly concerning to medical health researchers who study the unique health problems in the communities. This rate of diabetes is three to five times higher in First Nations communities than in the general population. “We’re not completely sure why,

Western prof examines diabetes in First Nations

but clearly there’s a genetic predisposition to environmental changes in this population,” Harris said. “If you look back at diabetes in First Nations, it didn’t exist four decades ago.” Harris also explained there are some environmental factors that cause higher diabetes and obesity rates in the First Nations population.

“We know that there are very high rates of obesity and inactivity in this population,” Harris explained. “There are lots of other important dynamics involved with First Nations people […] and major problems regarding socio-
economic challenges.” According to Harris, the combination of genetic and environmental factors complicates the diabetes story. Harris’ program aims to help pregnant First Nations women either prevent diabetes due to weight gain, or manage the disease to prevent harm to the child. “Part of the focus of the project is learning how to manage not only blood sugar control, but also teaching a healthy lifestyle program,” Harris said. Harris said the program is already showing results in helping pregnant women manage their health. “It’s certainly increased awareness around the need to be screened for diabetes during pregnancy, because screening rates are very low in general for on-reserve First Nations women,” he said. “Once diagnosed, it’s important to facilitate a community-based lifestyle program that focuses on physical activities—it’s basically a walking support program.” Harris also hope the program will pay dividend long after it’s over. “Our hope is that, even at the end of the program, the communities will have well-developed intervention programs that are community-based that will be ongoing for future First Nations women.”

Western to play host to space summit Cam Smith News Editor It’s one small step for space researchers, but one giant leap for Western. This year’s annual Canadian Space Summit will be held by Western’s own Centre for Planetary Science and Exploration. According to a press release, upwards of 100 delegates from the Canadian and international space community will be attending the summit. Among them, Harrison Schmitt, the last Apollo 17 astronaut on the moon, will be lecturing to the public November 16, in the Natural Sciences Building. “The Space Summit brings together participants from the private, government and academic sectors, who are working in and are interested in the development of space exploration in Canada,” Alyssa Gilbert, outreach coordinator for the CPSX, explained. “It acts as a venue to discuss recent scientific advances and exchange new ideas and information about space exploration.” Western’s thriving space exploration studies influenced the decision to have it host this year’s summit. “The Centre for Planetary Science and Exploration is the largest research group of its kind in Canada, and is one of the largest in North America,” Gilbert said. “It acts as a centre for the field in Canada, and is therefore an ideal place
to host a conference that will unify the Canadian space sector.” According to Gordon Osinski, a professor in the departments of earth sciences and physics and astronomy, and co-chair of the event, this year’s summit agreed with the choice of venue. “One of the things that’s been happening at Western is its growing emphasis on planetary science and exploration,” he explained. “This is the right time to be bringing it to Western.” For Osinski, this year’s summit holds particular relevance because of the excited state of the space community. “It’s changing times in the space industry—both within Canada and internationally,” he explained. “It’s bringing us together to have a discussion and take stock of where we’ve come from, and to think about where Canada should be going in the future.” According to Gilbert, Schmitt’s speech is not directly related to the summit. “Dr. Schmitt’s panel discussion and the public lecture on November 16 are not actually part of the summit,” Gilbert said. “However, because of the interest of the Space Summit attendees, it was a perfect time to host our Planetary Science Annual Distinguished Public Lecture. Dr. Schmitt will be talking about the future of human space exploration, and his lecture will be about his experience on Apollo 17.”
