A review of the evidence for a neuroendocrine link between stress, depression and diabetes mellitus
ABSTRACT Obesity and type 2 diabetes continue to be major public health burdens with type 2 diabetes rising in epidemic proportions. Since known risk factors do not explain all of the variance in the population, it is important to identify novel risk factors that can lead to development of new preventive measures. Chronic psychological stress and depression are associated with type 2 diabetes but the mechanism remains unclear. Neuroendocrine changes induced by these stressors, specifically activation of the hypothalamic-pituitary-adrenal (HPA) axis and sympathetic nervous system (SNS), might provide a unifying explanation. The objectives of this review are (1) to summarize the metabolic impact of HPA axis and SNS dysfunction induced by depression and stress, (2) to summarize the relation of neuroendocrine parameters to risk factors for diabetes, (3) to discuss the limitations of assessing neuroendocrine function in population-based and intervention studies, and (4) to summarize the evidence of the impact of stress reduction, by cognitive behavior therapy (CBT), on neuroendocrine factors and on outcomes in diabetes and obesity.

- "This buffering effect might even attenuate some of the physiological load associated with chronically high blood sugar. This may take place through reduced chronic activation of stress-responsive pathways such as the hypothalamic-pituitary-adrenal axis, via effects on the regulation of inflammation and the adaptive immune response (Golden, 2007; Segerstrom and Miller, 2004). Women do sometimes report satisfaction related to these roles, and other scholars have noted how families evaluate the merits or demerits of wives based on the quality of family care that those wives provide (Cohen, 2000; Dern e, 1995).

ABSTRACT: Biocultural models of health and illness are increasingly used to trace how social pathways shape biological outcomes. Yet, data on the interactions between social and biological aspects of health are lacking in low- and middle-income regions, where two-thirds of all type 2 diabetes cases occur. This study explored health, social roles, and biological correlates among a group of 280 type 2 diabetic and non-diabetic women (n = 184 diabetic) in New Delhi, India, between 2009 and 2011. Using a biocultural framework, we developed and tested a series of hypotheses about the relationships that might exist between diabetes, psychological distress, social role fulfillment, and biological markers measuring blood sugar control, generalized inflammation, and immune stress. Although blood glucose and glycated hemoglobin levels indicated that women's diabetes was generally poorly controlled, they lacked the elevated inflammation, immune stress, and mental ill health that often accompany uncontrolled blood sugar. Qualitative work on explanatory models of diabetes and gendered models of appropriate behavior demonstrated that despite living with poorly controlled diabetes, women maintain participation in culturally valued roles involving the care of others. We suggest that behavioral congruence with these gendered roles may buffer diabetic women's mental health and perhaps even their long-term physical health, while simultaneously posing challenges for their diabetes self-care. To our knowledge, this is the first study to explore the experience of type 2 diabetes in India from an integrated biocultural perspective. Copyright © 2015 Elsevier Ltd.

- "Activation of the hypothalamic–pituitary axis due to stress results in excess secretion of cortisol, leading to increases in blood glucose levels and, eventually, insulin resistance (Black, 2006; Golden, 2007). Additionally, activation of the sympathetic nervous system and the subsequent release of epinephrine and norepinephrine can lead to abdominal obesity and insulin resistance (Black, 2006; Golden, 2007). PTSD is also associated with unhealthy behaviors such as poor diet and physical inactivity, which are risk factors for diabetes (Dedert et al., 2010; Pietrzak et al., 2011). "
ABSTRACT: Objective To explore the temporal relationship between 9/11-related posttraumatic stress disorder (PTSD) and new-onset diabetes in World Trade Center (WTC) survivors up to 11 years after the attack in 2001. Methods Three waves of surveys (conducted from 2003 to 2012) from the WTC Health Registry cohort collected data on physical and mental health status, sociodemographic characteristics, and 9/11-related exposures. Diabetes was defined as self-reported, physician-diagnosed diabetes reported after enrollment. After excluding prevalent cases, there were 36,899 eligible adult enrollees. Logistic regression and generalized multilevel growth models were used to assess the association between PTSD measured at enrollment and subsequent diabetes. Results We identified 2143 cases of diabetes. After adjustment, we observed a significant association between PTSD and diabetes in the logistic model [adjusted odds ratio (AOR) 1.28, 95% confidence interval (CI) 1.14–1.44]. Results from the growth model were similar (AOR 1.37, 95% CI 1.23–1.52). Conclusion This exploratory study found that PTSD, a common 9/11-related health outcome, was a risk factor for self-reported diabetes. Clinicians treating survivors of both the WTC attacks and other disasters should be aware that diabetes may be a long-term consequence.Preventive Medicine 09/2014; 66.

- "Indeed, these patients might be worried about complications related to their poor glycemic control. In addition, anxiety could deteriorate glycemic balance via adrenergic hyperactivity  . We did not find a relationship between depression and diabetes balance; this has also been the case in several other studies on the subject   . "
ABSTRACT: Objectives. To estimate the prevalence of anxiety and depression using the Hospital Anxiety and Depression Scale (HADS) in a population aged over sixty years with type 2 diabetes and to study the impact of anxiety and depression on glycemic balance and disease outcome. Results. The prevalence of anxiety and depression in the 62 subjects included in the study was, respectively, 40.3% and 22.6%. We found a relationship between these disorders and complicated diabetes. The subjects having an imperfectly balanced diabetes had a higher average anxiety score than those having a good glycemic control (9.1 ± 4.2 versus 6.5 ± 3.1; P = 0.017). No relationship was found between diabetes balance and depression. Conclusion. Association between anxiety and depressive disorders and diabetes is frequent and worsens patients' outcome, in terms of diabetes imbalance as well as in terms of diabetic complications. Our study shows that there is need for physicians to detect, confirm, and treat anxiety and depressive disorders in elderly diabetic patients.Depression research and treatment 06/2013; 2013:341782.
