Marriage Keeps Your A1C Low

Married older adults have lower A1C levels than single ones, in line with a recent study published in BMJ Open Diabetes Research & Care. Surprisingly, even strained and unsupportive relationships show a positive effect.

Why would marriage keep your blood sugar low? Read on to learn the way it would work.

The Relationship Between Social Health and Physical Health

While it could look like one’s marital status and metabolism shouldn’t have much to do with one another, experts know that social health could be very vital to physical health. Because the National Institutes of Health explains, “wide-ranging research suggests that strong social ties are linked to an extended life. In contrast, loneliness and social isolation are linked to poorer health, depression, and increased risk of early death.”

These associations are particularly strong for individuals with, or susceptible to developing, type 2 diabetes. Previous studies have found that friendship and community engagement are significant diabetes risk aspects. Loneliness, for instance, may double the chance of type 2 diabetes.

The connection between social and metabolic health is incredibly complex, but there are likely several aspects at play:

  • Social angst can trigger a chemical stress response, including excessive secretion of the hormone cortisol, which causes inflammation, heightened glucose levels, and insulin resistance.
  • Loneliness, stress, and depression may also negatively affect eating behavior, increasing sugar cravings and other poor dietary selections.
  • Living with a partner or spouse may aid you feel more motivated to make healthy lifestyle selections. Partners may help to buffer stress, an effect that may deliver direct health advantages, reminiscent of reducing the inflammation that is very related to diabetes.
  • Marriage may also help relieve financial stress — shared income and resources could make an enormous difference.

Romantic relationships could also be especially vital later in life, as most individuals have less contact with children and friends as they age.

The Recent Study

The brand new study was led by Katherine J. Ford, PhD, a postdoctoral fellow with the Department of Psychology at Ottawa’s Carleton University. Ford and her coauthor assessed several thousand English adults between the ages of fifty and 89. The study participants didn’t have diabetes.

(“Marriage,” for the record, doesn’t have to seek advice from legal marriage — respondents were counted as “married” in the event that they lived with a partner.)

Adults in marriages (or cohabitating relationships) had an A1C that was 0.2 percentage points lower than single adults. That’s about 20% as powerful as the typical A1C reduction related to diabetes drugs like metformin or sulfonylureas.

That modest improvement has an incredible effect when it’s spread across a bigger population: A 2001 Norwegian evaluation quoted by Dr. Ford’s paper contended that “a population reduction of 0.2 percent A1C … would scale back total mortality by … 10 percent.”

The result was consistent in each men and ladies.

It’s also vital to notice that the researchers tried to account for confounding aspects reminiscent of age, BMI, employment, and smoking status. Within the sample, single adults were more likely to be older, smoking, and fewer physically lively, all major known diabetes risk aspects. The evaluation adjusted for all of them to assist isolate the effect of marriage alone.

Unhappy Relationships

In fact, everyone knows that bad relationships, whether with friends, family, or lovers, can have a negative effect on our mental health, increasing stress levels and driving unhealthy behavior.

Participants in the brand new study were asked questions on how supportive their spouses/partners were (Could they depend on them? Did they feel understood?) and the way strained their relationships were (Did they get on one another’s nerves?). The researchers expected that strained and unsupportive relationships would have a less positive metabolic effect.

Surprisingly, though spousal support and spousal strain had no relationship to A1C. That’s to say, individuals with apparently unsupportive marriages enjoyed the identical blood sugar advantages as individuals with completely happy ones. It seems that just living with a partner — even one which doesn’t seem particularly supportive — may lead to the identical glucose-controlling effect.

It’s tough to place an excessive amount of credence into anyone study, in fact, and the outcomes of an evaluation of individuals without diabetes may not pertain to individuals with the condition. The authors noted that a previous study on adults with diabetes found that spousal support did matter. The authors speculated that diabetes, a serious health challenge, requires more lively support.


Marriage may help control your A1C. A brand new study suggests that married older adults (without diabetes) have significantly lower blood sugar levels than single ones. Even strained, less-supportive relationships seem to assist.

Though this one study isn’t enough to prove that marriage has a glucose-lowering effect, it dovetails with an immense amount of medical research associating social health with physical and metabolic health. Individuals with vibrant social lives — romance, friendship, and community involvement — are inclined to be healthier. They experience less physical stress and are in a great position to make healthier lifestyle decisions.

Relationships are vital, especially for older adults!
