Bachelors, Divorcees, and Widowers: Does Marriage Protect Men from Type 2 Diabetes?
Researchers examined the role of marital status in the development of type 2 diabetes. Using prospective data from the Health Professionals Follow-up Study, researchers found that unmarried men (especially widowers) had an elevated risk of developing type 2 diabetes, when compared to married men (adjusting for other factors). This increased risk may be partially mediated by unfavorable changes in lifestyle, diet, and adiposity.
