“Preventing obesity and smoking can save lives, but it doesn't save money, researchers reported Monday. It costs more to care for healthy people who live years longer, according to a Dutch study that counters the common perception that preventing obesity would save governments millions of dollars.
"It was a small surprise," said Pieter van Baal, an economist at the Netherlands' National Institute for Public Health and the Environment, who led the study. "But it also makes sense. If you live longer, then you cost the health system more."
In a paper published online Monday in the Public Library of Science Medicine journal, Dutch researchers found that the health costs of thin and healthy people in adulthood are more expensive than those of either fat people or smokers.
On average, healthy people lived 84 years. Smokers lived about 77 years, and obese people lived about 80 years. Smokers and obese people tended to have more heart disease than the healthy people.
The results counter the common perception that preventing obesity will save health systems worldwide millions of dollars.
"This throws a bucket of cold water onto the idea that obesity is going to cost trillions of dollars," said Patrick Basham, a professor of health politics at Johns Hopkins University who was unconnected to the study. He said that government projections about obesity costs are frequently based on guesswork, political agendas, and changing science.
Van Baal described the paper as "a book-keeping exercise," and said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a higher chance of dying of something more expensive later in life.”
