Do You Meet the Simple Seven?

In public health school, you learn there are three levels of preventive medicine. Primary prevention would be like trying to prevent someone at risk for heart disease from getting his or her first heart attack. Secondary prevention is when you already have the disease and are trying to prevent your second heart attack, and tertiary prevention is like cardiac rehab, where you’re just trying to reduce the complication rates. A fourth level was suggested in 2000, quaternary prevention, trying to reduce the damage from all the drugs and surgery from the first three levels. But people seem to forget about a fifth concept, introduced by the World Health Organization back in 1978, termed primordial prevention, which is being embraced by the American Heart Association’s 2020 strategic impact goals

Primordial prevention was conceived as a strategy to prevent whole societies from experiencing epidemics of the risk factors. The corresponding strategy at the individual level is to prevent the development of risk factors. Instead of trying to prevent someone with high cholesterol from getting a heart attack, why not prevent them from getting high cholesterol in the first place?

So, the American Heart Association came up with the simple seven, featured in my video, How Many Meet the Simple Seven?. These health behaviors or factors include not smoking, not being overweight, being “very active” (defined as walking at least 22 minutes a day), eating a few fruits and veggies, having below average cholesterol, normal blood pressure, and normal blood sugars. 

Their goal was to reduce heart disease deaths by 20% by 2020. Why so modest an aim? An improvement of 25% was deemed “unrealistic,” and 15% was considered insufficient; so, they decided on 20. If 90% of risk can be thrown out the window by engaging in simple lifestyle modifications, why is just 25% considered unrealistic? To understand, one must realize just how bad our diets have gotten.

The most common reason patients give for not complying with a cholesterol-lowering diet may be the presumption that they’re already eating healthy and so don’t need to change. But if you look at the status of cardiovascular health in U.S. adults, only about 1% of Americans have a bare minimum of healthy eating behaviors, such as five-a-day fruits and veggies, eating beans, whole grains, and drinking less than three cans of soda a week. What percentage of Americans hit all seven of the simple seven? 14,000 men and women were surveyed, and most had two or three, but hardly any had all seven simple health components. Just how low a prevalence was having seven out of seven? Only about 1 out of 2,000 Americans had all seven factors intact. And the one they were missing the most was diet.

Unfortunately, unhealthy behaviors extend into the medical profession. Just like smoking doctors are less likely to tell their patients to stop smoking, and couch potato docs are less likely to push exercise, or things like more fruits and vegetables; we need to role-model healthy behavior. This greatly enhances our credibility and effectiveness. Gone are the days of traditional authority when the fat physician, dropping cigarette ash down his gravy-stained vest, could credibly prescribe a change in behavior.

Lifestyle medicine, the use of diet and lifestyle changes to prevent and treat disease, can be not only cheaper and safer, but also more effective. See, for example:
