【The key point of this article】Marriage relations are helpful for blood sugar control. Even in an unhappy marriage, it is better than single-body health. Its glycated hemoglobin is on average 21% lower than those who are single-body, divorced or lost a partner. Couples can affect each other's behavior, and have higher shared incomes, which can bring healthy diets. People who have changed their marriages (such as divorce) have obvious changes in glycated hemoglobin, which shows signs of prediabetes. Research results show that health is closely related to human relations, and marriage or cohabitation is beneficial to blood sugar control. --by ChatGPT

In recent years, experts have been emphasizing that "social isolation" is not good for health. More studies have now pointed out that even in an unhappy marriage, it is more helpful to health than a single body, especially in blood sugar control.

It was previously discovered that marriage can bring many health benefits compared to individuals, including longer health, lower risk of moderate wind, heart disease and depression, and generally have a healthier diet. Experts believe that couples can affect each other's behavior (such as dietary habits), have a higher shared income, and can also bring healthier diets.

Researchers want to further understand how marital relationships affect blood sugar, and they analyzed data from more than 3,300 adults aged 50 to 89 in the English Longitudinal Study. Researchers asked them whether they had a husband, wife or accompanies, and how much pressure and support they had in their relationship. The blood samples collected every four years will be analyzed together with the collected data. The results found that glycated hemoglobin in married or cohabiting people, on average, is one in five (21%) less than those who are single, divorced or lose their partner, and the results are also applicable to both men and women.

Interestingly, whether harmonious or intimate, the relationship between the two people has no significant impact on the average blood sugar, which proves that supportive relationships are beneficial to health. Those who have changed their marriages (such as divorce) have obvious changes in glycated hemoglobin, which shows signs of prediabetes. Katherine Ford, an Ottawa University of Carlton who led the study, said the study showed that health is closely related to human relations, whether the relationship between spouses and partners is harmonious, and marriage or cohabitation is beneficial to blood sugar control.

The study was published in the BMJ Open Diabetes Research & Care journal.
