问题               Fat Question and Reference Point of the United States
    In late June the Centers for Disease Control and Prevention launched its LEAN Works Web site, a clearinghouse of information on the health costs of employing fat people replete with recommendations on how to prevent and control obesity. The site uses an " obesity cost calculator" to determine the added price of employing somebody with a body-mass index (BMI) of over 30, the threshold for obesity. The calculator asks employers to fill out a company profile including type of industry and location, employees’ BMIs, and their wages and benefits. The software then estimates the " costs for medical expenditures and the dollar value of increased absenteeism resulting from obesity".
    But is the federal government’s endorsement of a device that essentially demo-nizes the 72 million Americans who fit the official definition of obese justified by the science? Dr. William Dietz, director of the CDC’s Division of Nutrition, Physical Activity and Obesity, defends the site as one weapon in the larger war on fat. " We see this epidemic as a serious threat to health and serious medical cost," Dietz says. "We didn’t feel like we could wait for the best possible evidence, so we acted on the best available evidence."
    Other experts, however, say BMI is a crude tool that fans fears of an obesity epidemic even as it fails as a reliable measure of an individual’s health. "We made everyone fat by framing! That is the real epidemic," says Paul Campos, a law professor at the University of Colorado who coauthored a controversial study questioning whether obesity is a true health crisis or a moral panic.
    The American Heart Association lists obesity as major risk factor for heart disease because it raises blood pressure, increases "bad" cholesterol while lowering "good" cholesterol, and carries an elevated risk of developing diabetes, itself a risk factor for heart disease. In addition, obesity has been linked to a wide range of health problems, including cancer, asthma, and sleep apnea.
    Nevertheless, it’s hardly clear that there actually is an obesity epidemic, or that fat people are at greater risk of death than people of normal weight, or that weight loss—relentlessly promoted by public-health officials as the solution to America’s weight problem—is an attainable goal at all.
    When we talk about the obesity epidemic, it’s important to understand where the numbers come from. Most large-scale evaluations of public fatness—including the CDC’s—employ BMI, a calculation that uses an individual’s height and weight to determine whether he or she is underweight (BMI less than 18. 5), normal weight (BMI between 18.5 and 24.9), overweight (BMI between 25 and 29. 9), or obese (BMI of 30 or higher). BMI calculations can be famously ridiculous—Dallas Cowboys quarterback Tony Romo’s BMI of 28.8 (he’s 6 feet 2, 224 pounds) puts him at the upper end of the overweight category.
According to the American Heart Association, obesity______.

选项 A、may lead to sleeping problems
B、decreases your blood pressure
C、certainly develops into diabetes
D、is helpful to prevent cancer

答案A

解析 推理判断题。根据题干关键词the American Heart Association定位到第四段。该段末句提及“肥胖还被与大范围的健康问题想联系,包括……睡眠窒息",[A]含义与之相符,故为正确答案。[B]含义与原文相反,故排除;[C]含义绝对化,故排除;该段末句提及,肥胖可能导致癌症,故排除[D]。
