问题 单项选择题 案例分析题

某女,40岁。身高160cm,体重65kg,平时喜爱吃甜食,不爱运动。

该女子体重指数(BMI)为()

A.18.4

B.21.5

C.23.7

D.25.4

E.40.6

答案

参考答案:D

解析:

1.BMI的具体计算方法是以体重(公斤,kg)除以身高(米,m)的平方,即BMI=体重(妇)/[身高(m)]2在判断肥胖程度时,使用这个指标的目的在于消除不同身高对体重指数的影响,以便于人群或个体间比较该女子的BMI=65/(1.6×1.6)=25.4。

2.我国卫生部发布的《中国成人超重和肥胖症预防控制指南(试用)》中规定的中国的分类标准是BMI<18.5为体重过低,18.5~23.9为体重正常,24~27.9为超重,≥28为肥胖。该女子的BMI为25.4,故为超重。

3.控制膳食与增加运动相结合以克服因单纯减少膳食能量所产生的不利作用。两者相结合可使基础代谢率不致因摄入能量过低而下降,达到最好的减肥效果。

     It's great fun to explore (探索) new places-it feels like an adventure, even when you know

you're not the first to have been there. But make sure not to get lost or waste time going round

in circles.

     Do the map reading if you're being driven somewhere.It'll be easier if you keep turning the

map so it follows the direction you're traveling in Keep looking ahead so that you can give the

driver lots of warning before having to make a turn, or you'll have to move to the back seat.

     Get a group of friends together and go exploring.You'll need a good map, a compass

(指南针), a raincoat,a cell phone to call for help in case you get lost, and a bit of spare cash

for emergencies (应急现金). Tell someone where you're going before you set out and let

them know what time you expect to be back. The test is in not getting lost, not in seeing how

fast you can go, so always stick together, waiting for slower friends to catch up.

a compass to find your way. This can be done as a sport, with teams trying to find the way

from A to B (and B to C, etc. ) in the fastest time, or simply as a spare-time activity. Either

way, it's not only good fun, but a great way to keep fit.
