There are more and more single people in our country. The marriageable single population has exceeded 200 million, and the adult population living alone has exceeded 77 million. Correspondingly, the marriage rate in China has dropped to the lowest point in 20 years, and the divorce rate has tripled. 
Single life is free and unrestrained, giving up a lot of responsibilities and pressures in marriage and family, and should live more easily. The truth, however, is that unmarried people tend to have a higher risk of dying than their married peers. Western scholars in the 19th century tended to use “marriage choice theory” to explain this phenomenon, arguing that when people choose marriage partners, they are more willing to choose those healthier partners, It is not surprising that those who are physically and mentally deficient are not selected, that is to say, those who are “single” are people with poor health and high risk of death. However, the “marriage selection theory” is not always correct, because in addition to individual flaws, there are also talented scientists in the unmarried population. The higher the education level, the longer the average life expectancy, and it is precisely this group of highly educated talents who are less likely to enter the palace of marriage. Therefore, after the “marriage choice theory”, the “marriage protection theory” has emerged, which believes that people can get more emotional support in marriage and help relieve stress. , reduce loneliness; after marriage, under the supervision of your partner, you are more likely to develop good living habits; when you are sick, your partner will take you to see a doctor in time… These factors all lead to a lower risk of death for married people than unmarried people. possible reasons. Considering that most of the previous studies were carried out in Western countries, and there was little data in Asia, then, in East Asia, which was influenced by Confucian culture and attached great importance to marriage and family relations, How does marital status affect our mortality risk? Recently, scientists from Japan Cancer Center Cancer Control Institute, from the Asian Cohort Consortium（the Asia Cohort Consortium） The marriage and health records of more than 600,000 people in four countries, including China, Japan, South Korea and Singapore, were collected and analyzed.Unmarried people had a 15% higher risk of all-cause mortality than married people, and Male unmarried persons or unmarried persons younger than 65 years of age had a more pronounced increase in the risk of death. The study was published in JAMA Network Open. Note: The Asian Cohort Consortium is a long-term follow-up study of at least 1 million healthy individuals focusing on various risk factors and health outcomes in Asian populations. 
623140 of 326397% of participants, including 3263 ) and 296,743 males (47.6%), 86.4% were married, the mean age at enrollment was 53.7 years, and the mean follow-up time was 15.5 year. During the follow-up period, a total of 123,264 participants died, including 37,394 from circulatory disease, 8,013 from coronary heart disease, and 14,563 from cerebrovascular disease. 41,362 people died from cancer, 13,582 from respiratory diseases, and 7,795 from accidents. Compared with married people, unmarried people had a 15% higher risk of death from all causes, a 12% higher risk of death from cerebrovascular disease, and a higher risk of death from coronary heart disease The risk of death from circulatory diseases was 20% higher, the risk of death from circulatory diseases was 17% higher, the risk of death from cancer was 6% higher, the risk of death from respiratory diseases was 14% higher, and the risk of death from accident was 19% higher. If the unmarried people are further subdivided into four statuses: single, separated, divorced and widowed, Compared with married people, single people are more The risk of death increased by a full 62 percentage points, followed by divorced 38 percent, separated 35 percent, and widowed 9 percent. After excluding participants who died during the first five years of follow-up(to avoid the impact of poor health on the study results), the conclusion still established. 
If analyzing by gender,Marital status had a more significant impact on men’s health. Compared with married men, unmarried men had a 23% higher risk of all-cause mortality, while women’s marital status was not significantly associated with all-cause mortality risk. The explanation given by the researchers is that married women need to undertake housework and parenting, which may neutralize some of the health benefits of marriage; of women have more job opportunities and are financially stable, and the resulting health benefits offset the health losses of being unmarried. In addition, the impact of marital status on the risk of death is also age-related. Compared with married people of the same age, the mortality risk of unmarried people aged 65 is significantly higher than Unmarried people over the age of 65, especially single people under the age of 65, had the most significant increase in the risk of death(HR, 1.79; 95% CI, 1.54-2.08). Compared with unmarried people under the age of 65, it is clear that unmarried seniors over 65 are more likely to receive care and support from relatives and the community. Help the health of the elderly. All in all, this study confirms that marriage does affect our health. It is said that young couples are old companions. In the long life, we are grateful for the support and support of the people around us. Accompanying, when we grow old, maybe we will be more aware of this. Finally, remember to love single friends a lot. Your love and care are enough to ignite the hope of a single person.
