Cohabiting adults have lower blood sugar levels, study finds

Researchers say couples need not get along to benefit, and social isolation may increase type 2 diabetes risk

People who cohabit with a partner have lower blood sugar levels, even if they do not get along with them, according to a study that warns social isolation may increase the risk of type 2 diabetes.

The researchers believe that living with someone is an important source of social support for adults in mid to later life, according to the study published in the British Medical Journal's diabetes journal. They found the effects were the same regardless of whether the relationship was harmonious or acrimonious.
