对于多重心脏病发作的风险来说，你的腰围可能比体重更重要

Heart attack survivors who carry extra weight around their belly are at greater risk of another heart attack, new research has found, another reason why measuring your waist may be more important than stepping on the scale.

一项新的研究发现，那些腰围超标的心脏病幸存者患心脏病的风险更大。这也是为什么称腰围比称体重更重要的另一个原因。

It's been known for a while that having a pot belly, even if you are slim elsewhere, increases the odds of having a first heart attack, but the latest study, which published Monday in the European Journal of Preventative Cardiology, is the first time researchers have found a link between belly fat and the risk of a subsequent heart attack or stroke.

人们早就知道，即使你在其他地方很苗条，拥有大腹便便也会增加首次心脏病发作的几率，但周一发表在“欧洲预防心脏病学杂志”上的这项最新研究，是研究人员首次发现腹部脂肪与随后心脏病发作或中风的风险之间存在联系。

The link was particularly strong in men, researchers said.

研究人员说，这种联系在男性中尤为明显。

"Abdominal obesity not only increases your risk for a first heart attack or stroke, but also the risk for recurrent events after the first misfortune," said Dr. Hanieh Mohammadi of the Karolinska Institute in Stockholm, in a news release.

“腹部肥胖不仅会增加第一次心脏病发作或中风的风险，还会增加第一次不幸发生后复发事件的风险，”斯德哥尔摩卡罗林斯卡学院的哈尼·穆罕默迪博士在一份新闻稿中说。

"Maintaining a healthy waist circumference is important for preventing future heart attacks and strokes regardless of how many drugs you may be taking or how healthy your blood tests are."

“保持健康的腰围对于预防未来的心脏病和中风很重要，无论你服用了多少药物或者你的血液测试有多健康。”

The study tracked more than 22.000 Swedish patients after their first heart attack and looked at the link between their waist circumference and events caused by clogged arteries like fatal and non-fatal heart attacks and stroke. Patients were followed for nearly four years, with 1.232 men (7.3%) and 469 women (7.9%) experiencing a heart attack or stroke.

这项研究跟踪了22000多名首次心脏病发作后的瑞典患者，研究了他们的腰围与动脉阻塞(如致命和非致命的心脏病发作和中风)之间的关系。研究人员对这些患者进行了近四年的跟踪调查，其中1232名男性(7.3%)和469名女性(7.9%)出现了心脏病或中风症状。

Most patients — 78% of men and 90% of women — had abdominal obesity, defined as a waist circumference of 94 cm (37.6 inches) or above for men, and 80 cm (32 inches) or above for women.

大多数患者(78%的男性和90%的女性)有腹部肥胖，定义为男性腰围94厘米(37.6英寸)或以上，女性腰围80厘米(32英寸)或以上。

The study found that belly fat was associated with heart attacks and stroke independent of other risk factors like smoking, diabetes, hypertension, body mass index and prevention treatments. The researchers stressed that waist circumference was a more important marker than overall obesity and advised doctors to measure their patient's waists to identify those at risk.

研究发现，与吸烟、糖尿病、高血压、体重指数和预防治疗等其他风险因素无关，腹部脂肪与心脏病和中风有关。研究人员强调，腰围是比整体肥胖更重要的标志，并建议医生测量病人的腰围，以确定哪些人有肥胖风险。

However, they said that the link was stronger and more linear in men, who made up nearly three-fourths of the patients included in the study, than women.

然而，他们说，与女性相比，男性的这种联系更强，线性程度更高，男性占研究患者的近四分之三。

The reason for this could be down to the type of fat that tends to hang out on men's and women's bellies. Mohammadi said some studies have suggested that men may have more visceral fat that goes deep inside your body and wraps around your vital organs.

究其原因，可能是因为男性和女性的腹部倾向于堆积的脂肪类型。穆罕默德说，一些研究表明，男性可能有更多的内脏脂肪，这些脂肪深入人体内部，包裹着重要的器官。

This fat can be turned into cholesterol that can start collecting along and hardening your arteries, perhaps ultimately leading to a heart attack or stroke.

这些脂肪会转化成胆固醇，开始聚集并使你的动脉硬化，最终可能导致心脏病发作或中风。

"In women it is thought that a greater portion of the abdominal fat is constituted by subcutaneous fat which is relatively harmless," she said.

她说:“人们认为，女性腹部脂肪的大部分是由相对无害的皮下脂肪构成的。”

However, the lower numbers of women included in the study meant the findings had less "statistical power" and more research was needed to draw definite conclusions, Mohammadi said.

然而，穆罕默德说，参与研究的女性人数较少，这意味着研究结果的“统计效力”较小，需要更多的研究才能得出明确的结论。
