(Reuters Health) — Workers who experience an increase in stress on the job over time may be more likely to develop diabetes than their coworkers who don’t, a recent study suggests.

Researchers examined data on 3,730 petroleum industry workers in China. At the start of the study, none of the workers had diabetes.

After 12 years of follow-up, workers who experienced increasing stressful tasks on the job were 57 percent more likely to develop diabetes, the study team reports in Diabetes Care.

At the same time, workers who experienced a decline in coping resources like social support from friends and family or time for recreational activities were 68 percent more likely to develop diabetes.

“Major changes in work may affect our risk of developing diabetes,” said Mika Kivimaki, a researcher at University College London in the UK who wasn’t involved in the study.

“It is therefore important to maintain a healthy lifestyle and a healthy weight, even during turbulent periods at work,” Kivimaki said by email.

In the study, Yulong Lian of Xinjiang Medical University and colleagues didn’t report exactly how many workers developed diabetes. Lian didn’t respond to requests for comment.

Worldwide, nearly one in 10 adults had diabetes in 2014, and the disease will be the seventh leading cause of death by 2030, according to the World Health Organization.

Most of these people have type 2 diabetes, which is associated with obesity and aging and happens when the body can’t properly use or make enough of the hormone insulin to convert blood sugar into energy. Left untreated, diabetes can lead to nerve damage, amputations, blindness, heart disease and strokes.

Physicians have long recommended exercise, weight loss and a healthy diet to control blood pressure and minimize complications of the disease. Stress reduction is also advised because, whether it’s caused on the job or not, stress may also make diabetes worse by directly contributing to a spike in blood sugar or by leading to unhealthy lifestyle habits that can cause complications.

The study looked at several forms of job-related stress and found that what researchers described as “task stressors” – such as feeling overloaded with work or unclear about expectations or responsibilities of the job, and the strains of physical labor – were the biggest contributors to the risk of developing diabetes.

So-called organizational stressors like interruptions, closures or poor communication didn’t appear to influence the odds of diabetes. Job control, or how much ability workers had to influence their day-to-day work activities, also didn’t appear to impact diabetes risk.

Among coping resources that influenced the risk of diabetes, declines in self-care and decreases in rational coping skills appeared to make the most difference, the study also found.

The study wasn’t a controlled experiment designed to prove whether or how changes in work stress or coping resources might influence the odds of developing diabetes.

Other limitations include its focus workers in a single, predominantly male industry and its reliance on stress and diabetes assessments at just two points in time.

Still, the findings add to evidence that stress can play a role in the development of diabetes and suggest that it’s worth paying closer attention to the specific role played by stress on the job, said Dr. Pouran Faghri, director of the Center for Environmental Health and Health Promotion at the University of Connecticut in Storrs.

“Stress has been associated with behavioral problems such as comfort or binge eating, consumption of high fat, energy-dense foods, poor dietary choices, physical inactivity and sedentary behavior,” Faghri, who wasn’t involved in the study, said by email.

“There is also an association with reduced sleep quality and negative psychological health such as depression, anxiety, insecurity, powerlessness and low self-esteem,” Faghri added. “These behavioral changes will lead to obesity and the development of type 2 diabetes.”

Diabetes and obesity both tied to higher risk of cancer

(Reuters Health) – Many cancer cases worldwide may happen at least in part because people are overweight or have diabetes, a new report suggests.

Diabetes and being overweight or obese were a factor in 5.6 percent of new cancer cases worldwide in 2012, or about 792,600 cases, the authors say.

Researchers examined rates of 12 types of cancer from 175 countries in 2012. Then, because cancer can take a long time to develop, they looked back at 2002 data on rates of overweight or obesity and type 2 diabetes, which is caused in part by obesity.

Overall, about 544,000 cancer cases, or about 3.9 percent of the total, were linked with a high body-mass index (BMI, a ratio of weight to height), and 280,000, or 2 percent, were linked with diabetes.

A BMI of 25 or higher indicates overweight, and a BMI of 30 or higher indicates obesity. (A BMI calculator is available online here: bit.ly/2tXeEf4.)

“Increases in diabetes and high BMI worldwide could lead to a substantial increase in the proportion of cancers attributable to these risk factors, if nothing is done to reduce them,” said lead study author Dr. Jonathan Pearson-Stuttard of Imperial College London in the UK.

“These projections are particularly alarming when considering the high and increasing cost of cancer and metabolic diseases, and highlight the need to improve control measures, and increase awareness of the link between cancer, diabetes, and high BMI,” Pearson-Stuttard said in a statement.

Worldwide, an estimated 422 million adults have diabetes and more than 2 billion adults are overweight or obese, researchers report in the Lancet Diabetes and Endocrinology.

Both high BMI and diabetes are risk factors for various types of cancer, potentially due to biological changes caused by these conditions – such as high insulin, high blood sugar levels, chronic inflammation, and dysregulated sex hormones such as estrogen.

The biggest proportion of cancer cases related to diabetes and high BMI – about 38 percent – occurred in high-income western countries, followed by east and southeast Asian countries at about 24 percent.

Although cancers are still less common in some low and middle-income countries than in high-income nations, these countries had particularly large impacts from diabetes and high BMI.

For example, between 9 percent and 14 percent of all cancer cases in Mongolia, Egypt, Kuwait, and Vanuatu were tied to high BMI and diabetes.

Globally, liver cancer and endometrial cancer contributed the highest number of cancer cases related to diabetes and high BMI, at 25 percent and 38 percent, respectively.

By 2025, growing rates of diabetes and obesity could contribute to a 30 percent increase in the number of cancers related to these conditions in women, and a 20 percent increase in related cancers in men, researchers estimated.

The study wasn’t a controlled experiment designed to prove whether or how diabetes or obesity directly cause cancer. Another limitation is that because many cancers can take years to develop, a decade-long study might underestimate the connection between cancer and these other health problems.

“Perhaps most surprising is that the already striking findings of the study are likely to be underestimates of the true impact of obesity and diabetes on cancer rates,” said Dr. Graham Colditz, author of an accompanying editorial and a researcher at Washington University School of Medicine in St. Louis, Missouri.

The biggest increases in weight and diabetes-related cancers were seen in low and middle-income countries, where rates of overweight and obesity have been rising dramatically in recent years, Colditz noted.

“It is hard to overstate the importance of working to maintain a healthy weight,” Colditz said by email. “It lowers the risk of multiple cancers – as well as diabetes, heart disease, liver disease, and arthritis.”

Does diabetes make a heart attack feel different?

(Reuters Health) – People with diabetes may not always feel classic symptoms like acute chest pain when they have a heart attack, according to a small study that offers a potential explanation for why these episodes are more deadly for diabetics.

Researchers examined data from detailed interviews with 39 adults in the UK who had been diagnosed with diabetes and had also experienced a heart attack. Most of the participants reported feeling some chest pain, but they often said it didn’t feel like they expected or that they didn’t think it was really a heart attack.

“Long term diabetes damages your heart in many ways (increased blocking of the heart’s blood vessels), but it also damages your nerves,” said study co-author Dr. Melvyn Jones of University College London.

“So a bit like a diabetic might not feel the stubbing of their toe, they also feel less pain from damaged heart muscle when the blood supply gets cut off, so they don’t get the classical crushing chest pain of a heart attack,” Jones said by email.

People with diabetes are three times more likely to die from heart disease than the general population and possibly six times more likely to have a heart attack, Jones added.

All patients in the study received care at one of three hospitals in London, and they ranged in age from 40 to 90. Most were male, and roughly half were white.

The majority had what’s known as type 2 diabetes, which is tied to aging and obesity and happens when the body can’t properly use insulin to convert blood sugar into energy. Four of them had type 1 diabetes, a lifelong condition that develops when the pancreas produces little or no insulin, a hormone needed to allow blood sugar to enter cells.

Many of the participants described heart attack symptoms such as chest pain and discomfort.

However, many felt like their pain wasn’t severe enough to be a heart attack or didn’t consider the discomfort they felt in their chest as similar to what they would expect with a heart attack.

This may have contributed to delays in seeking care, which are in turn associated with lower survival odds and a higher risk of complications and disability for people who do live through the event, researchers note in the journal BMJ Open.

The study was small, and it wasn’t a controlled experiment designed to prove whether or how diabetes might lead people to experience different heart attack symptoms.

Still, it confirms a longstanding belief that people with diabetes may be prone to atypical heart attack symptoms, said Dr. Deepak Bhatt, executive director of Interventional Cardiovascular Programs at Brigham and Women’s Hospital Heart and Vascular Center and a researcher at Harvard Medical School in Boston.

“Atypical means instead of the more classic chest pain or chest pressure, patients experience symptoms such as extreme fatigue or breathlessness, for example,” Bhatt, who wasn’t involved in the study, said by email.

“The biology of the heart attack is the same,” Bhatt added. “But the thought is that patients with advanced diabetes may have a degree of nerve damage (neuropathy) and therefore may be less likely to experience the more common chest pain or chest pressure from a heart attack.”

Patients with diabetes should understand that they’re more likely to have a heart attack than other people, said Dr. John Wilkins, a researcher at Northwestern University Feinberg School of Medicine in Chicago who wasn’t involved in the study.

“They should have regular follow-up with their physicians, keep their blood sugars well controlled, lead a heart-healthy lifestyle, avoid the development of cardiovascular risk factors like high blood pressure and high cholesterol, and if they have risk factors they should make sure they are appropriately managed,” Wilkins said by email.

“They should also be familiar with the symptoms that suggest that they might be having a heart attack or an impending heart attack and know how to respond if those symptoms develop,” Wilkins advised.

MANILA, Philippines — The residents of Iloilo City still have not seen their mayor, Jed Patrick Mabilog.

According to his spokesperson, Atty. Mark Piad, he already filed for a sick leave to seek treatment for his diabetes.

“We know that the mayor is suffering from diabetes mellitus, type 2 diabetes, and because of the stress that the mayor had gone through,” he said.

Mabilog has yet to return to the country after leaving for Japan last August 29 to attend the Citynet 10th Disaster Cluster Seminar in Yokohama.

The mayor will also use the break to spend time with his family abroad.

It was not mentioned which country Mabilog will be treated in.

Meanwhile, Atty. Piad admitted Mayor Mabilog has been receiving death threats.

However, it has nothing to do with him leaving the country.

Mabilog’s camp assured that he will return to face the allegations against him on his alleged involvement in illegal drug operations in the province. — Vincent Arboleda | UNTV News & Rescue
