While anxiety was at the top of my list of emotional states that generated office visits in my pediatric practice, depression always ran a close second. Not infrequently, patients would report symptoms that suggested they were harboring both morbidities.

Although some families appear to be prone to depression, I’m not aware that a definable genetic basis has been discovered. Like me, you may have wondered what factors determine whether an individual will become depressed or merely be unhappy when things aren’t going well. We all have known people who have weathered disappointment and life-altering calamities without even a hint of being depressed. On the other hand you probably have met numerous patients and acquaintances who have become significantly depressed as the result of simply worrying that some disaster might befall them.
Is this variable vulnerability to depression the result of some as yet undiscovered neurotransmitter? Or are there certain lifestyle features that make individuals more prone to depression? Or ... could it be both? In other words are there behaviors that can tweak a person’s telomeres in such a way that triggers a biochemical cascade that results in depression?
A recent paper in the American Journal of Psychiatry doesn’t drill down through the genetic and biochemical strata, but it does suggest that there are “modifiable” behaviors that may contribute to depression. The researchers based at Harvard Medical School in Boston accessed a database of more than 100,000 adults in the United Kingdom. With use of a two-stage method that included a strategy similar to that employed for identifying genetic risk factors for disease, the researchers scanned a large number of factors that they considered modifiable, searching for those that might be associated with the development of depression.

Not surprisingly, they discovered that those respondents who more frequently confided in others and more frequently visited with family and friends were less likely to become depressed. Of course, this protective effect of social connection can cut both ways during the pandemic. During this pandemic if those people you confide in are not currently in your “bubble,” you may have a problem. This may explain why, despite warnings of their dangers, bars continue to be so attractive. It’s probably not just the alcohol but it’s the bartenders and patrons who are willing to listen that patrons seek out. It would be helpful if more people felt comfortable sharing their feelings with members of their family bubble. But you and I know that many families don’t come even close to matching the Brady Bunch image of a functionality.
Somewhat surprisingly to the Harvard researchers was their finding that time watching television also was a significant risk factor for the development of depression. Their data did not allow them to determine whether this observation was linked to the sedentary nature of television watching or the content of the shows being viewed. I suspect that content is not the problem. But in addition to being a sedentary activity, television watching often is isolating. When television was first introduced to the mass market, families grouped around the household’s lone set, much as families did back when radios became popular. In their infancy radio listening and television viewing were social activities rich with discussion and shared emotions.
However, as televisions became less expensive and no longer required large pieces of furniture to house them, television viewing became a more solitary and individual activity. Televisions became obligatory furnishings of every bedroom, and parents and children could withdraw to their own spaces and be entertained free of any opportunity or obligation to interact with the rest of family.
This new research into the risk factors for depression suggests that again without any way of monitoring their usage. At least among children, television watching should be a modifiable behavior.
Dr. Wilkoff practiced primary care pediatrics in Brunswick, Maine, for nearly 40 years. He has authored several books on behavioral pediatrics, including “How to Say No to Your Toddler.” Other than a Littman stethoscope he accepted as a first-year medical student in 1966, Dr. Wilkoff reports having nothing to disclose.
