New government rescarch delivers some concerning news for U.S. teens - almost1 in 5 have prediabetes(前期糖尿病)，Young adults fared even worse- 1 in 4 of those aged 19 to 34 have prediabetes.
A person with prediabetes has higher than normal blood sugar levels. The levels aren't yet high enough to be considered type 2 diabetes. But often, people who have prediabetes go on to develop type 2 diabetes.
“Prediabetes is very common among adolescents and young adults. We want people to know that this is a serious health condition that raises the risk of developing type 2 diabetes, heart disease and stroke ,”said study author Linda Andes, a statistician with the CDC's Division of Diabetes Translation.
The good news ? "Prediabetes can be reversed." she said. "This can be a wake- up call to motivate people into action- eating a healthier diet, getting more physical activity and losing weight. ”
The researchers used data from nationally representative nutrition surveys that included almost 6, 000 teens and young adults. Blood sugar levels were assessed with three different testing methods. Other tests, such as blood pressure and cholesterol, were also done.
The study found that 18% of teens had prediabetes. For young adults, that number was 24% ， Obese teens and young adults were more likely to have
prediabetes. Male teens and young adults were far more likely to have prediabetcs than females.
Adolescents and young adults with prediabetes also had higher cholesterol and blood pressure, and carried more weight around their abdomen( 腹部 ) 。 Several
experts not involved with the study discussed the implications.
"The most significant issue I see is that even if a person does not go on to develop diabetes, prediabetes itself is associated with increased cardiometabolic(心血 管代谢) risks in many people."said Dr. Mary Pat Gallagher, director of the pediatric
diabetes center in New York City.
“This means that this group of people should undergo more careful screening and receive more intensive counseling about changes in lifestyle that could improve their health," she said.

32. D.由倒数第二段可知 D 项正确。由第工段第一句可知 A 项错误。由倒数第三段可知 B 项错误。由第三段可知。前期糖尿病患者的血糖水平高于正常水平,但还不至于高到被认为是 2 型糖尿病。通常情况下.前期糖尿病患者在未来的生活中会患上 2 型糖尿病,故 C 项错误。
33. B.从倒数第四段“研究发现.18%的青少年和 24%的青年人患前期糖尿病。肥胖的青少年和青年人更易患前期糖尿病。男性青少年和青年人患前期糖尿病的可能性远远高于女性。"可知。肥胖的男性青年人相比而言最容易患前期糖尿病。
34.A。从第四段可知”前期糖尿病是可逆的。这或许是一个激励人们采取行动的警示一吃得 更健康.加强体育锻炼和减肥。”故 A 正确,
35.A。主旨大意题。由文章第-段可知,本文围绕青少年和青年人普遍患有前期糖尿病为主题展开。其余三项太片面.
