Here’s a quiz: when the reported cases of a disease goes up, should researchers and policymakers interpret that to mean: A, some environmental factor has led to an actual increase in cases, B, the total number of cases hasn’t changed but doctors are better able to identify the condition, C, paranoia and hyper-awareness has led to over-diagnosis, or D, some or all of the above? The answer? It is often impossible to tell, but HCO suspects there is rarely one singular reason, that D will be right most of the time.
This question is something we should think about when considering a recent study released by the American Medical Association’s journal, which showed that the number of chronic debilitating conditions, such as obesity, ADHD, and a variety of neurological disorders went up 14% between 1994 and 2006. What could possibly be the cause of such a massive turn for the worse in children’s health?
One of the members of the research team that released the study, Dr. Neal Halfon of the UCLA Center for Healthier Children, Families and Communities, suggested that indeed, there are several reasons that we’ve seen the rate of some of these disorders shoot up 10 to 20 percent in the past few decades. He explained that the parameters for defining these diseases have changed, and this may have some impact on the increase, but also explained that worsening environmental factors have had a big influence in this phenomenon as well. While you can’t exactly misdiagnose obesity, in the case of Attention Deficit Disorder, a relatively modern disease, we are seeing both better awareness of what to look for and, we suspect, a great deal of over-diagnosis as a result of insistent parents inflated expectations.
This study also showed that despite the increase in instances, the children whose chronic condition persisted was merely 7.4%. Why should we be concerned with disorders that our children can usually shake off by the time they get into the real world? The answer, of course, is that these conditions have all kinds of lasting consequences and complications down the road (obesity in particular,) even if the original problem is no longer there. This means we’re going to be dealing with this surge of childhood diseases in the future in the form of increased insurance bills and larger federal healthcare deficits, something we’re kind of having a problem with already.
