“…The results extend our prior findings on psychosocial factors such as neuroticism and perceived discrimination as moderators of the relationship between adiposity and glucoregulation (Tsenkova, Carr, Coe, & Ryff, 2012; Tsenkova et al, 2010). Given the relationship between anger-out and neuroticism (Costa, McCrae, & Dembroski, 1989), it is important to note that the MIDUS assessment of neuroticism did not include underlying facets, one of which is angry hostility (McCrae & Costa, 2003).…”

OBJECTIVE Anger has been linked to cardiovascular disease, but few studies have examined the relationship between anger and type 2 diabetes. The aim was to investigate associations among different indicators of anger expression, adiposity, and nondiabetic glucose metabolism in a national survey of adults. RESEARCH DESIGN AND METHODS Participants were 939 adults without diabetes in the Midlife in the US study (MIDUS II). Glucose metabolism was characterized by fasting glucose, insulin, insulin resistance, and glycosylated hemoglobin (HbA1c). Spielberger’s Anger Expression inventory was used to measure suppressed anger (anger-in), expressed anger (anger-out), and controlled anger (anger-control). We investigated the relationship between anger and glucose metabolism, and whether anger amplified the adverse relationship between body weight distribution (body mass index=BMI and waist-to-hip ratio=WHR) and glucose metabolism. RESULTS Multivariate-adjusted analyses revealed an association between anger-out and both insulin and insulin resistance. As predicted, anger-in amplified the relationships between BMI and insulin and insulin resistance, while anger-out amplified the association between WHR and insulin and insulin resistance. Low anger-control was associated with higher glucose. None of the three anger measures was significantly associated with HbA1c. CONCLUSIONS Our findings extend previous research on anger as a potential risk factor for type 2 diabetes by demonstrating that anger expression is associated with clinical indicators of glycemic control, especially among those with pre-existing risk due to obesity and high central adiposity.

“…However, whether and to what extent such effects can lead to long-term changes in the basic personality factor impulsivity or what the variance proportion of such an influence on the overall personality variance proportion could be, is not yet clear and requires appropriate prospective analyses in the future. Moreover, there is also comparatively good evidence from previous studies that impulsivity or related personality traits are potential risk factors for the development of type 2 diabetes or behaviors which are risk factors for later developing diabetes [29,[34][35][36] Moreover, self-reports may be influenced by social desirability and may thus be complemented by observer ratings in future research. However, since the questionnaires were answered online and patients were anonymous social desirability is assumed to play a minor role [72].…”

“…It has been associated with worse diabetes self-management in type 1 diabetics [32,33]. For type 2 diabetes, an association between diabetes diagnosis and impulse control disorders (particularly eating disorders) was found [22] and impulsivity or related personality traits have been identified as potential risk factors for the development of type 2 diabetes and behaviors that are themselves risk factors for the later development of diabetes [29,[34][35][36][37]. There is also evidence that hypoglycemia can lead to increased impulsive behaviors [38][39].…”

Objective Impulsivity is marked by insufficient reflection and forethought, whereas Need for Cognition (NFC) also referred to as cognitive motivation or intellectual engagement is marked by elaborated thinking. The aim of this study was to investigate the potential role of these personality traits as resilience or risk factors, respectively, in diabetes self-management and glycaemic control. Further, it was examined whether diabetes-specific self-efficacy could serve as a mediator of these relationships. Design/Measures Data of 77 participants with type 2 diabetes was ascertained, using self-report instruments for NFC, impulsivity, diabetes-specific self-efficacy, and diabetes self-management. Glycemic control was assessed by the biomarker HbA 1c. Results While NFC was strongly positively associated with diabetes self-management and glycemic control, impulsivity showed a reverse pattern. Results of simple and serial mediation models showed that the effects on diabetes self-management and HbA1c of both, impulsivity and NFC, were mediated by self-efficacy. Conclusion The moderate to high standardized coefficients suggests that NFC might be an important protective factor and impulsivity a possible risk factor for effective diabetes self-management and glycemic control. These traits could be applied for an easy-to-use questionnaire

The Prevalence and Correlates of Mental and Emotional Health Among American Indian Adults With Type 2 Diabetes

Aims The purpose of this study was to examine the prevalence and correlates of mental and emotional health factors among a sample of American Indian (Indigenous) adults diagnosed with type 2 diabetes. Methods Data are from a community-based participatory research project involving two Indigenous reservation communities. Data were collected from 218 Indigenous adults diagnosed with type 2 diabetes via in-person paper-and-pencil survey interviews. Results Reports of greater numbers of mental/emotional health problems were associated with increases in self-reported hyperglycemia, comorbid health problems, and health-impaired physical activities. Conclusions This study addresses a gap in the literature by demonstrating the associations between various mental/emotional health factors and diabetes-related health problems for Indigenous Americans. Findings underscore the importance of holistic, integrated primary care models for more effective diabetes care.
