Married couples not only live longer than singles, but the life gap between the two groups is growing according to a cohort study in Asia.
Researchers found that in Asia, married couples die 20 percent less frequently from any cause than unmarried couples. This is based on a cohort study of more than half a million people.
According to a study published in the journal JAMA Network Open, married couples have a 20 percent lower risk of death from heart disease and external factors such as accidents.
The study examined the medical records of over 623,000 people from mainland China, Taiwan, Japan, Singapore, and South Korea over a 15-year period, with an average age of 54.
Researchers found that people who are single have a 17 percent higher risk of circulatory system diseases and a 14 percent higher risk of respiratory illnesses than those who are married.
The study suggests that men of all ages and both genders under 65 are especially likely to benefit from marriage.
Married men live longer than unmarried men; those who marry after 25 get more protection than those who tie the knot at a younger age, and the longer a man stays married, the higher his survival advantage over unmarried men.
Those who have favorable socio-economic and psychological status are more likely to tie the knot, which may explain why married people live longer.
A similar link has been found between marital status and mortality in previous studies, but they mostly focused on Western populations.
Married Couples and Family
Married couples in Southeast Asia are also more likely to live with extended family and have stronger family ties, according to a recent study.
Single-earner households in Asian societies faced higher financial burdens and pronounced marital selection outcomes, according to the study.
According to the study, “married individuals are more likely to survive than unmarried individuals.”
The region’s economic growth, however, has led to an increasing number of young adults in Asia avoiding marriage, despite potential health benefits.
As living costs rise and individuality and diversity grow in urban China, change is particularly rapid.
Newlywed couples in China have declined for eight years in a row. This is because they have fallen by nearly 50 percent from 13.47 million in 2013 to 7.6 million last year, according to official Chinese data.
In response to a survey conducted by the Communist Youth League last October, 44 percent of Chinese women aged 18 to 26 from urban areas and a quarter of urban men said they would not marry.
