Reаding Cоmprehensiоn Questiоns Whаt is the аuthor’s main idea in this article? In paragraph 10, the author states, “This pushed the number of Americans who need to lower their cholesterol from 13 million to 36 million. The panel urged people to eat better and exercise more — but, tellingly, its leaders noted that drugs might be an easier solution.” Explain what this quotation means, and how it relates to the main idea. Provide your own example of something that is considered a “quick fix.” Pill-popping Replaces Healthy Habits By Steven Findlay If you watch enough TV these days, you might get the impression that there's a prescription drug for just about anything that ails you. And that's about right. In recent years, more and better drugs have come along to treat the chronic diseases and conditions afflicting us: arthritis, diabetes, asthma, coronary-artery narrowing, heartburn, allergies, depression, and erectile dysfunction. U.S. pharmacies dispensed more than 3 billion prescriptions in 2003, up from about 2 billion a decade ago. We love our medicines. And why not? They are so easy, and they usually work. We take more and more of them, even as we complain bitterly about their prices and rail against the pharmaceutical industry. But another perspective goes down less easily: Although many Americans don't get the medicines they need, as a nation, we are fast becoming overly reliant on a slew of drugs that essentially substitute for a healthy lifestyle. Most of us don't routinely eat wholesome foods in moderate quantity, stay active or manage our body weight. One in five of us still smoke. When the inevitable consequences follow, we count on pills to counter the ills that our human weaknesses engender and our culture fosters (think ubiquitous fast, fatty foods and physical education's demise in schools). This has every bit as much impact on the steeply rising national tab for prescription drugs as their prices do. Unless Americans, individually and collectively, begin to take more responsibility for their own health, that tab may rise to a point where more serious limits will be imposed on our access to drugs. Evidence: The predicted costs of medicines compelled Congress to limit the drug benefit it added to Medicare to stay within a self-imposed 10-year budget of $400 billion. Now the Bush administration has raised that projection to $534 billion, even as the AARP and others begin to push to expand the new benefit. The drug industry correctly notes that many medicines can save money by preventing hospitalizations or nursing-home care and reducing disability. But it's just as true that the industry's success builds on our failure. Growth in costs could be reduced sharply if more people took basic steps to maintain their health and so needed fewer drugs or other medical care. Consider the cholesterol-lowering drugs known as statins. They are among the most widely prescribed medicines: Sales topped $13 billion in 2002, up from $1.8 billion a decade earlier. Lipitor alone earned Pfizer more than $6 billion last year in the U.S., the most of any drug. Some 15 million Americans take a statin daily. Statins are highly effective, lowering the risk of heart attack and stroke by an average of 20% to 30% among people at risk. But their use has soared largely because more and more people are identified as "at-risk" due to obesity, clogged arteries, diabetes, and high blood pressure, which, in turn, are linked to overeating, poor diet and lack of sufficient physical activity. In 2001, for example, a National Institutes of Health panel changed the at-risk standard for "bad" (LDL) cholesterol and said many more people with other heart-disease-risk factors also should lower their cholesterol. This pushed the number of Americans who need to lower their cholesterol from 13 million to 36 million. The panel urged people to eat better and exercise more — but, tellingly, its leaders noted that drugs might be an easier solution. "We used to say to try lowering (cholesterol) with diet first, but now we say that if your LDL is above 130 and you have coronary disease, you should be on drug therapy," Scott Grundy, a physician, and the panel's chairman told The Wall Street Journal. For people with LDL levels between 100 and 130, he added, "We think the evidence justifies the majority going on drugs." Recent studies add to the momentum. One showed the benefits of lowering LDL to 70 or 80. Two studies last year revealed that children and teens with high LDL levels show early signs of heart disease. These studies, trumpeted in the media, largely were seen as further evidence that even more Americans, maybe up to 50 million, could benefit from statins. Less noticed was a study out last July that found that a diet rich in fiber and soy protein lowered LDL levels about as much as a statin. OK, OK: Soy protein may be too much to ask. But a large body of research shows that a healthy, balanced diet and regular exercise can keep high cholesterol at bay for most of us — and yields multiple other benefits to boot, including a lower risk of some cancers. The cholesterol story is not unique. This same dynamic plays out for other ills and the drugs that treat them: high blood pressure, type 2 diabetes, certain kinds of pain, sleep disturbances, heartburn, even mild depression. Yes, millions of Americans with such conditions need medicines. But millions of us are self-afflicted with such ills because we can't or won't get our lifestyle acts together. We devour fad diets, such as Atkins and South Beach. But obesity rates have climbed steadily for 20 years. Two-thirds of us now are overweight. What we really want — admit it — is a trusty, safe anti-fat pill. Indeed, that's the Holy Grail of the pharmaceutical industry. The looming question is whether we can afford in the long run to allow the drug industry to bail us out of our bad habits. Drugs will get better, but not cheaper. It's our choice: Let drug costs spiral upward and drug firms capitalize on our weaknesses. Or take charge of our own health and reduce the overall need for pills.
