A Counterintuitive Approach to Lowering Cholesterol in Children


 

With the flip of the calendar a few short weeks ago, gyms and fitness centers began ramping up their advertising campaigns in hopes of attracting the horde of resolution makers searching for a place where they can inject some exercise into their sedentary lives. A recent survey by C.S. Mott’s Children’s Hospital found that even young people are setting health-related goals with more than half of the parents of 11- to 18-year-olds reporting their children were setting personal goals for themselves. More than 40% of the young people listed more exercise as a target.

However, our personal and professional experiences have taught us that achieving goals, particularly when it comes to exercise, is far more difficult than setting the target. Finding an exercise buddy can be an important motivator on the days when just lacing up one’s sneakers is a stumbling block. Investing in a gym membership and sweating with a peer group can help. However, it is an investment that rarely pays a dividend. Exercise isn’t fun for everyone. For adults, showing up at a gym may be just one more reminder of how they have already lost their competitive edge over their leaner and fitter peers. If they aren’t lucky enough to find a sport or activity that they enjoy, the loneliness of the long-distance runner has little appeal.

A recent study on children in the United Kingdom suggests that at least when it comes to teens and young adults we as physicians may actually have been making things worse for our obese patients by urging them to accept unrealistic activity goals. While it is already known that sedentary time is responsible for 70% of the total increase in cholesterol as children advance to young adulthood an unqualified recommendation for more exercise may not be the best advice.

In an interview with the study author, Andre O. Agbaje MD, MPH, said that in his large study population “light physical activity outperforms moderate to vigorous physical activity by five to eight times in lowering lipids”. While we may be surprised by this counterintuitive finding, Dr. Agbaje points out that an increase in sedentariness from 6 to 9 hours per day translates into a loss of 3 hours of light physical activity. In other words if you’re not sedentary you must be standing at attention or engaged in some light activity.

In my experience, and I suspect yours, it is difficult to get adults to do something, particularly if that something involves exerting energy, even a small amount of energy. The general admonishment of “be more active” is often met with a blank stare and the sometimes unspoken question “Like what?”

You could fall into a bottomless trap with them by suggesting a long list of activities, many of which are probably ones you do or would enjoy but don’t happen to fit with any of their interests or capabilities. Your chances of hitting on a perfect activity that the patient will attempt, let alone adopt, is very slim. Those of you with more patience than I have may choose to persist with this strategy. You could argue that even if the patient only dabbles briefly in one of your recommended activities, this is a minor victory worth celebrating. Who knows? The brief jolt of energy they received from this activity may prompt them to seek and find something else that works.

My interpretation of Dr. Agbaje’s findings is this: If we are going to suggest more activity, aim low. Don’t even mention the heavily weighted words “sport” or “exercise,” which are likely to dredge up bad memories. For adults, “Go shopping” or “Visit a friend” may be sufficient to at least get the person off the couch and on their feet and moving, even if very briefly.

The second message from this study applies more to children and adolescents and is one of those unusual instances in which a negative intervention may be more effective than a positive approach. Acknowledging that we are likely to have difficulty finding even a light activity that the child enjoys, why not pivot to the other side of the equation? Make a list of the child’s primary sedentary “activities.” Then suggest the parents put the child on a couch potato diet by immediately cutting in half the time he or she spends being sedentary. By definition, this will automatically increase his or her light physical activity by 50%. According to Dr. Agbaje’s data, this should be more effective in lowering lipids than in the unlikely event of finding a moderate activity the child accepts.

You can argue that the child will hound his or her parents unmercifully asking to be entertained. This may be true and this persistent complaining will be more likely to come from the older the child and the longer that the child has been allowed to be sedentary. Although the child may appear to have lost the ability to self amuse, I contend this isn’t a permanent loss and, with parental help, self-generated activity is a skill that can be regained if sedentary behavior is curtailed. This is another example of how saying “No!” in the right circumstances is often the most effective remedy for an unhealthy situation. I would never claim saying “No” is easy and helping parents to learn how to say “No” is one of our most difficult challenges. But, nothing else seems to be working.
