英国研究人员在最新一期《美国流行病学杂志》上报告说，工作压力过大容易让人发胖，紧张忙碌的上班族应注意自我舒缓压力。

  @; i" k. ~& qwww.csuchen.de　　研究人员共对6895名男性和3413名女性进行了长达19年的跟踪调查，被调查者在调查开始时的年龄在35岁至55岁之间。调查过程中，这些人会定期提交有关工作压力大小的调查问卷。结果发现，那些至少在三次问卷中表示自己工作压力大的人，比从未感觉工作有压力者的肥胖可能性要大73%。

Chronic stress has been linked to heart disease and the metabolic syndrome, a constellation of symptoms including excess belly fat that increases the risk of diabetes and cardiovascular disease, Brunner and his team note. They hypothesised that job stress might make people more likely to develop obesity during adulthood as well.www.csuchen.de8 b3 O1 ~* H+ o

Adjusting for factors that could be related to both job strain and obesity, such as socioeconomic status and cigarette smoking, reduced the relationship by only a small amount.

The findings provide "firm evidence that high psychological workload, together with lack of social support at work, acts as a causal factor for obesity," Brunner and his colleagues conclude.
