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.
Health—whether psychological or physical—is characterized not just by the absence of disease but increasingly by the presence of well-being. These researchers looked at the relationship between psychological well-being (marked by optimism, happiness, and life purpose) and serum antioxidants such as carotenoids and Vitamin E, which are indicators of physical health.
