your environment may put you at risk for diabetes

your home, your groceries, your neighbourhood are among factors that determine your chances of the disease

when you think of the main culprit for diabetes, it probably extends to the usual: excessive sugar and an inactive lifestyle.
but there are many other risk factors you wouldn’t expect to have a great effect on your glycemic control. the food selection at your local grocery store, where your home is built, your annual earnings, and the air quality in your neighbourhood.

cold temperatures can help decrease risk 

in a 2017 study published in the canadian medical association journal , researchers found that cold winter weather could help reduce the risk of gestational diabetes for pregnant people. in an interview with dr. gillian booth, the lead author of the study and a professor in the department of medicine at the university of toronto and scientist at the map centre for urban health solutions at st. michael’s hospital, she says being exposed to an environment of 16c for two hours was enough to activate brown fat—a part of our tissue that generates heat and metabolism when exposed to cold weather.

compared to 18, 19, or 24c, booth saw differences in activation of brown fat. “a few degrees makes a large difference which means with climate change, there will be more swings, more extreme weather, and more days in the year spent with high temperature and hot weather, so it could have an effect on a number of cases of gestational diabetes.”

although this study specifically applies to gestational diabetes, booth says there may be a different correlation with type 2 diabetes. she mentions her colleagues have seen seasonal variations with hyperglycemia (high blood sugar, a defining characteristic of diabetes) with rates of blood sugar peaking in january, with lower rates from april to june.
however, this may be due to the fact that people tend to eat poorly and are less active during the winter. “temperature and season affects how we change our behaviour,” says booth.

your postal code matters

how close you live to major roads and industrial areas will affect your risk of diabetes as much as your family’s ethnic background. in another study by booth , she found the high rates of diabetes in the peel region in ontario stemmed from the region’s diverse population and the suburb’s planning. people of south asian and caribbean descent are more susceptible to developing diabetes than caucasians, plus  many peel residents live close to high-traffic intersections and wide streets — resulting in neighbourhoods with low walkability and high traffic pollution.

there have been multiple studies drawing the link between air quality and diabetes. a three-year study published in the journal diabetes  found that air pollution increased latino children’s risk for developing type 2 diabetes. a new study published from the university of british columbia, researchers found that air pollution is the fourth-highest risk factor for death in the world.

a large study published in the lancet planetary health that followed 1.7 million american veterans and measured particulate matter—often created from cars—in the air found there was a significant association between a person’s risk of diabetes and the air they breathed. the belief is that these particulate matter contain toxic metals and when a person breathes in these pollutants, it enters their bloodstream and causes inflammation and increase insulin resistance.

poverty is a risk factor

according to toronto public health’s research report card, the rise in diabetes among lower-income groups has been the fastest growing, more so than any other group.
“there’s been a lot of public health efforts to put diabetes on the radar. initiatives to make people more aware of calories in restaurants, for example,” says booth. “but whether people can apply that knowledge into their lives is going to be different based on their background and abilities to pay for a gym membership or a personal trainer.”
from fruits and vegetables to milk and gas, people are paying more today than a decade ago to live healthily, says booth.
“we’ve known that poverty is a risk factor for diabetes and there’s a lot of factors that make it more likely that someone from lower income groups will develop type 2 diabetes,” she says. “there’s a lot of social and broader things that make it harder for lower-income groups to be healthy. the cost of living has risen dramatically making it much more difficult for people from lower-income groups to be healthy.”
