New research suggests that women who work 45 hours or more per week have a higher risk of type 2 diabetes than women who work 35 to 40 hours per week. week. week
The authors of the study do not know exactly why work might increase the risk of diabetes, or why the link was found only in women. But they suspect that this might have something to do with the hours of work without pay that women tend to do at home, more than men.
"It is important to understand that the work environment plays an important role in the risk of type 2 diabetes and other chronic diseases, work long hours is not not a good thing, "said the main author of the study. Peter Smith Smith is a senior scientist at the Institute of Work and Health in Toronto.
"If you look at time away from work, women take care of family members more and do more routine housework, the only thing women do not do is to see television and exercise, "added Smith.
Type 2 diabetes is on the rise. It is estimated that by 2030 worldwide, 439 million people will be living with the disease, an increase of 50% over 2010, according to researchers.
Diabetes is a major risk factor for other chronic diseases, such as heart disease and stroke, the team noted.
Obesity and a sedentary lifestyle are known risk factors for type 2 diabetes, but genetics also has a role, according to the American Diabetes Association.
The current study included more than 7,000 adult workers from Ontario, Canada. The participants, followed for about 12 years, were between 35 and 74 years old.
During the study period, one in 10 developed diabetes .
The researchers took into account factors such as age, sex, marital status, paternity, ethnicity, residence, lifestyle, weight, smoking and any chronic illness. They also included factors such as shift work, number of weeks worked per year, and whether the job was active or sedentary.
The study found no statistically significant association between hours worked by men and the development of type 2 diabetes.
But among women work 45 hours or more was associated with "an increase of at least 50 percent in the risk of developing diabetes," Smith said.
But it should be noted that the study was able to show that an association between several hours' work and diabetes, since it was not designed to prove causality.
The authors of the study suggested that working long hours can lead to a stress response that can lead to hormonal imbalances and insulin resistance that may contribute to the development of diabetes.
Dr. Joel Zonszein, director of the Diabetes clinical center at the Montefiore Medical Center in New York, reviewed the results.
He said that many things could explain sexual difference, including responsibilities in the family and at work, sleep problems, depression and the perception of a high total workload for jobs and unpaid work. House.
"Working 45 hours or more a week may be associated with an increase in the incidence of diabetes and of course, in [Estados Unidos] many people have two jobs, so they could work a lot more." Hours that our neighbors in Ontario quote, "said Zonszein.
