A big waistline is a warning for serious medical conditions such as heart disease, stroke and Type 2 diabetes. And here's a new one. Obese people who carry excess fat around their midriffs have lower vitamin D levels.
腰围粗是对一些重大疾病的警告，例如心脏病、中风和2型糖尿病。现在又有新消息了。肥胖人群（腹部有多余脂肪）的维生素D水平更低。
That's a quarter of UK adults. Dutch researchers recommend that people who are overweight with larger than normal waistlines should have their vitamin D levels checked. They found that the amounts of both total and abdominal fat were associated with lower vitamin D levels in women, although abdominal fat had a greater overall impact.
英国有四分之一的成年人中了上述情况。荷兰研究员建议腰围过大的肥胖人群应该去检查一下自己的维生素D水平。他们发现：女性总脂肪和腹部脂肪的含量与更低的维生素D水平相关，尽管腹部脂肪的总体影响更大。
However in men, abdominal and liver fat was associated with lower vitamin D levels. In all cases the greater the amount of belly fat, the lower the levels of vitamin D were.
然而对于男性而言，腹部脂肪和肝脏脂肪与更低的维生素D水平相关。在所有情况下，腹部脂肪越多，维生素D水平越低。
It's still unclear though if a lack of vitamin D contributes to abdominal fat storage or if obesity reduces the vitamin levels. Either way, vitamin D is important. Previous research suggests it lowers people's risk of developing conditions such as arthritis, asthma and Type 1 diabetes due to its anti-inflammatory effect and the positive impact it has on the immune system.
然而，目前尚不清楚究竟是缺乏维生素D导致腹部脂肪储存，还是肥胖降低了维生素D的水平。无论是何种情况，维生素D都很重要。先前的研究表明，维生素D能降低人们患关节炎、哮喘和1型糖尿病等疾病的风险，这是因为它的消炎作用和对免疫系统的积极影响。
Vitamin D, along with vitamins A and E, are fat-soluble vitamins. So, for instance, vitamin D needs to be dissolved in fat for our bodies to absorb it and use it. It also means that the body can store vitamin D in your fatty areas.
维生素D，以及维生素A和E，都是脂溶性维生素。所以，例如维生素D需要溶解在脂肪中，身体才能吸收并使用它。这也意味着身体会在脂肪区域存储维生素D。
In this study, Rachida Rafiq and colleagues from the VU University Center and Leiden University Medical Center in the Netherlands examined how the amount of total body fat and abdominal fat related to vitamin D levels.
在这项研究中，来自荷兰自由大学中心和莱顿大学医学中心的Rachida Rafiq及其同事研究了总体脂肪和腹部脂肪与维生素D水平的联系。
After adjusting for a number of possible influencing factors, including chronic disease, alcohol intake and levels of physical activity, they found that the amounts of both total and abdominal fat were associated with lower vitamin D levels, and abdominal fat had a greater impact.
调整了多种可能的影响因素后，包括慢性病、酒精摄入量和身体活动水平，他们发现总体脂肪和腹部脂肪量都与更低的维生素D水平相关，且腹部脂肪的影响更大。
Ms Rafiq said: "The strong relationship between increasing amounts of abdominal fat and lower levels of vitamin D suggests that ?individuals with larger waistlines are at a greater risk of developing deficiency, and should consider having their vitamin D levels checked.
Rafiq女士说道："腹部脂肪增多与更低的维生素D水平之间的密切关系表明：腰围更粗的人很有可能维生素D水平不足，应该考虑检查自己的维生素D水平。"
