(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.”

Overweight cops won’t get promoted, PNP chief warns

Robie de Guzman   •   February 13, 2020

MANILA, Philippines – The Philippine National Police (PNP) on Thursday reiterated its warning to its personnel to get fit and have a normal body mass index (BMI) or risk having a hard time getting promoted.

PNP chief General Archie Gamboa made this warning during the physical fitness and BMI tests of cops held in Camp Crame in Quezon City.

Of the 86 policemen who took the test, 32 are overweight, five are obese while 49 are of normal weight.

Those who failed to achieve their ideal weight would have to enroll in the Public Safety Officers Basic Course Class to reduce their weight.

“If you are enrolled in the schooling program, it’s like you still have time to redeem yourself. You are allowed to reduce your weight. So that’s why we are giving it a leeway,” Gamboa said in a media interview.

Gamboa warned that those who will fail to get their BMI to a normal level would not be allowed to file for promotion.

“’Pag hindi ka umabot doon the BMI mo mismo you will not be allowed to file for promotion which is a very first step in a promotional process,” he said.

BMI is a measure of body fat based on height and weight of a person.

Gamboa stressed that a police officer should take care of their health in order to perform their mandate in maintaining peace and order, enforce the law, prevent and control crimes and ensure public safety and internal security. – RRD (with details from Correspondent Lea Ylagan)

PNP to require normal BMI for police recruits

Aileen Cerrudo   •   August 19, 2019

The Philippine National Police (PNP) will strictly require normal body mass index (BMI) for police recruits.

The PNP said the National Police Training Institute will ensure that all police recruits will maintain their normal BMI before completing their basic training.

BMI is a person’s body fat based on height and weight. It is computed by dividing the person’s weight in kilogram with their height in meters squared.

A police recruit is underweight if their BMI is under 18.5 and they are overweight if their BMI is over 25 to 29.9.

Police recruits should maintain a BMI of 18.5 to 24.9 if they want to join the police force, according to PNP Spokesperson PBGen. Bernard Banac.

“Napakahalaga na lalo’t sila ay nagpapatrolya at nakahandang tumugon sa mga physical requirements katulad ng pagtugis ng mga mandurukot, mga snatcher kaya nilang habulin at gawin ang pagaresto, (It is important especially because they need to patrol and be prepared in responding to physical requirements like chasing robbers, and other kinds of arrest)” he said.—AAC (with reports from April Cenedoza)

Increased stress at work linked to higher risk of diabetes

(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.”
