Childhood Behavioral Problems Linked To Chronic Pain In Adulthood




It is well-known that there is an association between childhood behavioral problems and psychological problems later in life such as depression, anxiety, panic disorder and the like. However, until recently, there has not been a clear link between childhood behavioral problems and chronic pain in adulthood.

In a recent study, British researchers analyzed data gathered from following over 20,000 children beginning in 1958. This group, or cohort, was periodically assessed at different times over the course of over 40 years (at the ages of 7, 11, 16, 42, and 45 years). Behavioral data was gathered by using standardized measures and questionnaires; specific behaviors such as restlessness, stealing, obedience, lying, and bullying (among others) were looked at.

The study revealed that there indeed seems to be a link between severe behavioral disturbances in childhood and chronic pain in adulthood. For instance, the risk of having chronic pain at age 45 doubled for those individuals whose teachers had reported severe "persistent" behavior problems at ages 7, 11, and 16 years.

The mechanism for this association is believed to possibly be something called the hypothalamic-pituitary-adrenal (HPA) axis. Basically the HPA axis is a signaling system between brain structures (hypothalamus and pituitary) and the body (adrenal gland).

The HPA axis is intimately tied in with both emotions and stress on the one hand, and physiological responses on the other. In other words, it is a major "bridge" between the mind and the body, and as such is a good preliminary candidate for the link between childhood behavioral patterns and chronic pain later in life.

It is possible that in children with severe behavioral problems, HPA axis function becomes disturbed early-on, leading to persistent physical problems later in life. It is important to note that this is a very preliminary conclusion; there may be much more going on here, and further research is certainly needed..
