MONDAY, Sept. 19 (HealthDay News) -- Unless current health trends are reversed, five common, non-infectious diseases -- cancer, diabetes, heart disease, lung disease and mental health problems -- will cost the world $47 million in treatment costs and lost wages.
That's the conclusion of a new report, "The Global Economic Burden of Non-communicable Diseases," released by the World Economic Forum before the start Monday of a two-day United Nations summit on non-communicable diseases, CBS News reported.
"Until now, we've been unable to put a figure on what the World Health Organization (WHO) calls the 'world's biggest killers.' This study shows that families, countries and economies are losing people in their most productive years. The numbers indicate that non-communicable diseases have the potential to not only bankrupt health systems but to also put a brake on the global economy. Tackling this issue calls for joint action by all actors of the public and private sectors," Olivier Raynaud, senior director of health at the World Economic Forum, said in a news release.
The World Health Organization offered several steps that could help avert the impact of these chronic, non-communicable diseases. They include alcohol and tobacco taxes, smoke-free environments, and public-service campaigns to get people to cut down on their consumption of salt and trans fats. The organization said countries that have implemented such programs have already seen a "marked reduction" in the incidence of disease and deaths, CBS News reported.
These "non-communicable diseases" (NCDs) are now the leading cause of death worldwide by a wide margin. That's why health experts and leaders from 193 nations are meeting at the United Nations in New York City to discuss strategies to lower the death toll.
"This will be the first time that the U.N. has actually focused on the major killer of most people," said Dr. Otis Brawley, chief medical officer for the American Cancer Society, and a professor of oncology and epidemiology at Emory University in Atlanta.
"We need this," he added. "We need a chronic disease movement. We need to drive attention toward overall health. Because cancer, for example, kills more people in the world than HIV/AIDS, malaria and tuberculosis combined."
As analyzed in a report issued last week by the World Health Organization, non-infectious diseases are responsible for roughly 36 million fatalities worldwide every year. The loss in terms of life-years and productivity is staggering, since about 9 million of these deaths occur among men and women under the age of 60.
According to Dr. Gordon Tomaselli, president of the American Heart Association, "if current trends continue, well before the middle of this century [non-communicable diseases] will be responsible for more than three-quarters of the deaths around the world."
Heart disease currently accounts for the lion's share of these deaths, with WHO saying that 48 percent of non-communicable disease fatalities are attributable to cardiac illness. A little more than one in five non-communicable disease deaths are due to cancer, while respiratory illness is linked to slightly more than one in 10 fatalities. These are followed by diabetes, which claims the lives of 3 percent of non-communicable disease patients.
Poorer countries are often hardest hit by such diseases, the report noted, and by some measures their citizens bear a three times greater risk for dying from a non-communicable disease before the age of 60, compared with residents of richer nations.
"And the impact of the growing prevalence of non-communicable diseases is not only on the medical health, but the economic health of all nations, in direct care costs and that of lost productivity," Tomaselli said
Experts note that this health trend is occurring not only in poorer nations but also in the developed world, which has hardly proven immune to non-communicable diseases.
The WHO report found, for example, that non-communicable diseases account for 87 percent of all deaths in the United States. Not coincidentally, the United States is increasingly weighted down by an obesity epidemic, a largely inactive population (with a 43 percent sedentary rate), a 16 percent smoking rate, and markedly rising blood pressure and glucose levels.
Solving problems like that are the U.N. summit's main goal: to identify those steps that countries can take to promote healthful behaviors, blunting the impact of non-communicable diseases.
"This summit is a once-in-a-generation opportunity," the American Diabetes Association (ADA) said in a statement.
In fact, it's only the second time the U.N. has taken up a health issue -- the first, in 2001, created the Global Fund to Fight AIDS, Tuberculosis and Malaria.
The ADA noted that non-communicable diseases share many preventable risk factors, such as poor diet, insufficient exercise habits, smoking and alcohol abuse.
The ADA said those attending the upcoming summit will be shooting to achieve an ambitious but tangible goal: to curtail unhealthful behaviors and shave 25 percent off the global death rate from non-communicable diseases by 2025.
But Brawley emphasized that the U.N. effort to reach such goals will aim to build on existing public health initiatives, rather than usurp them.
"This is not a disease Olympics," he said. "And we are not in a competition. So the summit's aim is to focus the world on overall health. Not to the exclusion of infectious disease, but with the inclusion of non-infectious disease."
