The Prospective Contribution of Hostility Characteristics to High Fasting Glucose Levels: The moderating role of marital status

OBJECTIVE—To assess whether psychological constructs of hostility, anger, type A behavior pattern, and depressive symptom severity 1) were associated with concurrent and prospective fasting glucose levels and 2) whether this association was moderated by marital status

Psychosocial predictors of self-reported medical adherence in patients with heart failure over 6 months : an examination of the influences of depression, self-efficacy, social support, and their changes

Background Poor adherence to medical regimens is a serious problem that interferes with heart failure (HF) patients’ disease management and contributes to poor clinical outcomes. Few prospective studies have examined the psychosocial predictors of adherence over time in HF patients. Purpose This study examined the influences of depression, self-efficacy, social support, and their changes on self-reported medical adherence over 6 months in HF patients. Methods Participants were 252 HF outpatients, among whom 168 completed follow-up assessments. Hierarchical multiple regression analyses were conducted to examine whether psychosocial variables and their changes prospectively predicted adherence at 6 months, after adjusting for baseline adherence, age, gender, ethnicity, marital status, education, HF severity, medical comorbidity, and mental health treatment. Results Baseline self-efficacy (β = .22, p < .05), increase in self-efficacy (β = .34, p < .001), and decrease in depression (β = –.15, p = .05) predicted improved adherence over 6 months, but social support did not. In the combined model that included all significant psychosocial predictors from previous analyses, baseline self-efficacy (β = .37, p = .001) and its increase (β = .35, p < .001) emerged as independent predictors of improved adherence at 6 months. Conclusions Promoting self-efficacy and reducing depressive symptoms may be promising targets of behavioral interventions to facilitate long-term disease management in HF patients

Is the factor structure of the metabolic syndrome comparable between men and women and across three ethnic groups: the Miami Community Health Study

The metabolic syndrome (MS) is conceived as a cluster of disorders that increase risk for coronary heart disease and type 2 diabetes. Studies examining its structure primarily have used an exploratory factor analytic technique, but yielded discrepant results. There also is a lack of research that investigates whether the clustering pattern is similar across sex and ethnic groups. This study uses confirmatory factor analysis to evaluate the factor structure of the MS and examines its similarity between men and women and across three ethnic groups (Caucasian, African, and Cuban Americans). A hierarchical four-factor model with an overarching MS factor uniting insulin resistance, obesity, lipid, and blood pressure factors was tested with 517 individuals from the Miami Community Health Study. Findings show that the proposed structure was well supported (comparative fit index=0.97) and similar between men and women and across ethnic groups. The MS was represented strongly by insulin resistance, followed by obesity, lipid factors, and, to a lesser extent, a blood pressure factor. This study provides empirical support for identifying and diagnosing the MS by its component factors in a diverse population

Waist Circumference Moderates the Association Between Marital Stress and C-reactive Protein in Middle-Aged Healthy Women

The relationships among stress, obesity, and inflammation in women remain unclear. This study examined the relationships among marital stress, waist circumference, and C-reactive protein (CRP) in 201 healthy women from the Stockholm Female Coronary Risk Study. We tested whether marital stress was associated with CRP and whether this association was moderated by waist circumference. Hierarchical multiple regression revealed that after adjusting for age, occupation status, fasting glucose, apolipoprotein A1, apolipoprotein B, blood pressure, smoking, and menopausal status, marital stress was not directly associated with CRP. However, waist circumference significantly moderated the association between marital stress and CRP (p = 0.012) such that marital stress was significantly associated with higher CRP among women with larger waist circumferences but not in those with smaller waists. More obese women may be particularly vulnerable to the effects of marital stress by manifesting higher inflammation

Effect of negative emotions on frequency of coronary heart disease (The Normative Aging Study)

Negative emotions, such as depression and anxiety, have been associated with the development of coronary heart disease (CHD). In multivariate models, negative emotions have predicted CHD outcomes, such as nonfatal myocardial infarction and CHD mortality. Few studies, however, have investigated this relation while controlling for variables associated with the metabolic syndrome or those indicative of sympathetic nervous system activity. We prospectively examined the relation between negative emotions and incident CHD in older men (mean 60.3 ± 7.9 years) participating in the Normative Aging Study (NAS). Four hundred ninety-eight men who completed the Minnesota Multiphasic Personality Inventory (MMPI) and who participated in a subsequent laboratory assessment were included in the study. All men were not on medication and free of diagnosed CHD and diabetes. Negative emotions were measured by the MMPI Welsh A scale, which is comprised of 39 items measuring symptoms of depression and anxiety. Negative emotion score, sociodemographic characteristics, health behaviors, components of the metabolic syndrome, and stress hormones were used to predict incident CHD over a 3-year follow-up period. During follow-up, 45 CHD events were observed. In unadjusted logistic regression analyses, negative emotions significantly predicted the incidence of CHD (odds ratio [OR] 1.06, 95% confidence interval [CI] 1.01 to 1.10, p = 0.02). After adjusting for potential covariates, negative emotions continued to predict the incidence of CHD (OR 1.06, 95% CI 1.01 to 1.12, p = 0.02) A linear, dose-response relation was observed (chi-square 10.8, degree of freedom 2, p = 0.005): participants who had the highest level of negative emotions experienced the greatest incidence of CHD. © 2003 by Excerpta Medica, Inc

Utility of the Millon Behavioral Medicine Diagnostic to predict medication adherence in patients diagnosed with heart failure

Medication non-adherence is common and a primary reason for poor medical outcomes among individuals with heart failure (HF). This study's aims were to determine whether depression, hostility, and the personality-based Millon Behavioral Medicine Diagnostic (MBMD) Medication Abuse scale were associated with medication adherence (e.g., beta-blockers, ACE inhibitors, diuretics, statins) beyond contributions of demographic, medical, and psychosocial variables in an ethnically-diverse sample of 105 men and women diagnosed with HF. In hierarchical regression, greater MBMD Medication Abuse scale scores were associated with poorer adherence above and beyond both depression (β = .236, t[102] = 2.113, p = .037) and hostility (β = .244, t[102] = 2.506, p = .014). The Medication Abuse scale also completely mediated the relationship between adherence and depression. These findings suggest that personality measures such as the MBMD and hostility scales might be utilized in future studies investigating predictors of adherence and also used clinically to predict medication adherence among HF patients

Ethnicity and determinants of quality of life after prostate cancer treatment

To examine the quality of life (QOL) in a sample of men recently treated for localized prostate cancer to determine whether minority men are at greater risk of decrements in QOL and to identify factors that might explain disparities in QOL outcomes. The relationship between ethnicity and QOL was evaluated in a diverse sample of 204 men (85 non-Hispanic white, 37 African-American, and 82 Hispanic men). We also assessed associations with other factors known to be related to QOL (ie, sociodemographic, medical, and health behavior factors). Hierarchical regression analysis was used to assess the relationship between ethnicity and QOL. Factors that were anticipated to explain the ethnic differences in QOL were then added in stepwise analyses. Ethnic group membership was related to QOL such that minority men had lower QOL than non-Hispanic white men. In subsequent steps, the association between ethnic group membership and QOL was partially mediated by sociodemographic, medical, and health behavior factors, with each factor adding significant incremental variance (5%, 5%, and 17%, respectively). Three variables remained significant in the final model, which explained 37% of the variance in QOL scores: medical comorbidity, physical activity, and sleep functioning. Health behaviors appear to be strongly related to men’s QOL after prostate cancer treatment. Intervention studies aimed at improving QOL should include a brief assessment of health behaviors and may want to incorporate intervention components designed to address physical activity and sleep functioning
