A large prospective study of 734,626 women (mean age 60 years) in Britain found that after adjustment for socioeconomic, lifestyle and other factors, women who were married or living with a partner had a similar risk of developing ischemic heart disease (IHD) but a substantially lower IHD mortality compared to women who were not married or living with a partner during 8.8 years of follow-up. Studies conducted over several decades and on different populations have shown that being married is associated with a lower risk of all-cause mortality. Being married has also been associated with a lower risk of IHD mortality in men.英国一项包括734626名妇女（平均年龄60岁）的大型前瞻性研究经将近9年随访发现，在调整了社会经济状况和生活方式等多种因素后，与未婚或同居的妇女相比，已婚或同居的妇女罹患缺血性心脏病的风险相当，但病死率大幅降低。几十年来在不同人群中进行的研究已经表明，结婚与各种原因死亡率较低有关。结婚也与男性缺血性心脏病死亡率较低有关。
