每天喝4杯咖啡的女性 尿失禁的風險更大

Women who drink at least four caffeine drinks a day are more likely to develop frequent problems with bladder control.
每天喝至少4杯含咖啡因飲料的女性更有可能患膀胱控制的常見問題。

A new study of 65,000 American women found that those with the highest caffeine intake - equivalent to four or more cups of coffee or ten cans of soda a day - were more likely to develop urinary incontinence over four years.
由6.5萬美國女性所做的研究表明那些具有最高咖啡因攝入量的人——等於每天喝4杯咖啡或10罐汽水——更有可能在四年後患上尿失禁。

The study found no increased Risk among women consuming about three cups of coffee or less per day.
研究發現每天喝3杯或少於3杯咖啡的女性不會增加患病的風險。

In the most highly caffeine group, caffeine was particularly related to urge incontinence, a type where leakage happens after a sudden, strong urge to urinate.
在大部分高咖啡因組中，咖啡因跟急迫性尿失禁尤其有關，這是一陣突然強烈要小便的慾望，然後就排出來了。

The findings were reported in the Journal of Urology.
這些結果發表在《泌尿學雜誌》中。

Dr. Mary K. Townsend, one of the researchers on the work, said: 'We only observed an increased risk of urinary incontinence among women with the highest intakes of caffeine.'
這項工作的一個研究人員Mary K. Townsend博士稱：“我們只觀察那些高咖啡因攝入量的女性增加患尿失禁的風險。”

She said it is too early to give women specific advice on caffeine intake, adding that more studies are needed to confirm the current results, Reuters reports.
她說現在給女性關於咖啡因攝入量提建議還太早，還需要更多的研究來證實現在的結果，路透社報道。

Mrs Townsend, of Harvard Medical School in Boston, said women who already have urinary incontinence are commonly told to limit their caffeine intake.
波士頓哈佛醫學院的Mrs Townsend說，患有尿失禁的女性一般都要限制她們的咖啡因攝入量。

She said: 'Our study suggests that avoiding higher caffeine intake might also be useful advice for women who do not have urinary incontinence, but are concerned about developing it.'
她說：“我們的研究表明避免更高的咖啡因攝入量對沒有患尿失禁但擔心患病的女性來說也是有用的建議。”

She said caffeine might promote incontinence because it is a diuretic - it promotes flushing of water from the body - and people who already have an overactive bladder may be more susceptible to those effects.
她說咖啡因能導致尿失禁因爲它是一種利尿劑——它促進水分從身體排出——而且膀胱過度活躍的人更容易受這些結果的影響。

There's also evidence, she said, that even low doses of caffeine can speed muscle contractions in the bladder.
她說，還有證據證明甚至低劑量咖啡因也會加速膀胱的肌肉收縮。

Urinary incontinence is about twice as common in women than men, and its likelihood rises with age. One large U.S. study found that almost one-quarter of women in their 60s and 70s said they had urine leakage at least once a month; the rate rose to one-third among women in their 80s.
尿失禁發生在女性身上是發生在男性身上的大約兩倍，並隨着年齡的增加可能性上升。美國一家大研究發現大約1/4女性在60~80歲間每月至少有一次尿失禁；這個比例在80多歲的女性身上升到1/3。

Risk factors for urinary incontinence include obesity and past pregnancies with vaginal births.
患上尿失禁的風險因素包括過度肥胖和過去懷孕的陰道分娩。
