What Are The Lifetime Medical Costs Associated With Obesity?
A new research paper published in PLoS Medicine suggests that preventing obesity might result in increased public spending on medical care. Many
countries are currently developing policies aimed at reducing obesity in the population. However, it is not currently clear whether successfully
reducing obesity will also reduce national healthcare spending or not. Pieter van Baal and colleagues, from the National Institute for Public Health
and the Environment in the Netherlands, created a mathematical model to try to answer this question.
In their study, van Baal and his co-workers created three hypothetical populations of 1000 men and women, all aged 20 years at the start: a group of
obese, never-smoking individuals; a group of healthy-never smoking individuals of normal weight; and a group of smokers of normal weight. The model
produced an estimate of the likely proportion of each group who would encounter certain long term (chronic) diseases, and then estimated what the
approximate cost of medical care associated with each disease was likely to be. The researchers found that the group of healthy, never-smoking
individuals had the highest lifetime healthcare costs, because they lived the longest and developed diseases associated with aging; healthcare costs
were lowest for the smokers, and intermediate for the group of obese never-smokers.
However, the authors argue that although obesity prevention may not be a cure for increasing expenditures, it may well be a cost-effective cure for
much morbidity and mortality and importantly contribute to the health of nations.
A Perspective by Klim McPherson, from Oxford University in the UK, who was not involved in the study, discusses the implications of these findings and
comments that "it would be wrong to interpret the findings as meaning that public-health prevention (e.g., to prevent obesity) has no benefits";
the quality of life experienced by individuals, and other factors, must also be taken into account when planning interventions aimed at improving
public health.
