Metabolic pathways link childhood adversity to elevated blood pressure in midlife adults.

Childhood adversity is a risk factor for adult health outcomes, including obesity and hypertension. This study examines whether childhood adversity predicted mean arterial pressure through mechanisms of central obesity and leptin, adiponectin, and/or insulin resistance, and including dietary quality. 210 Black/African Americans and White/European Americans, mean age=45.8; ±3.3 years, were studied cross-sectionally. Path analyses were used to specify a chain of predictive variables in which childhood adversity predicted waist-hip ratio and dietary quality, circulating levels of hormones, and in turn, mean arterial pressure, adjusting for race, gender, and antihypertensive medications. Direct paths were found between childhood adversity, waist-hip ratio, and leptin levels and between leptin and dietary quality to mean arterial pressure. Systolic and diastolic blood pressures were similarly predicted. Early adversity appears to developmentally overload and dysregulate endocrine systems through increased risk for obesity, and through a direct impact on leptin that in turn, impacts blood pressure.

Attachment and the metabolic syndrome in midlife: the role of interview-based discourse patterns.

OBJECTIVE: Adult attachment discourse patterns and current family relationship quality were examined as correlates of health behaviors and number of metabolic syndrome (MetS) criteria met, and as mediators of the link between childhood adversity and these health outcomes. METHODS: A sample of 215 white/European American and black/African American adults aged 35 to 55 years were examined using a cross-sectional study design. Discourse was assessed with the Adult Attachment Interview, using coherence (a marker of attachment security), unresolved trauma/loss (a marker of disorganized cognitions related to trauma or loss), and idealization (minimizing stressful experiences and their impact) scores. Relationship quality, adverse childhood experiences, and current depressive symptoms were assessed, as were health behaviors of diet, exercise, and smoking. MetS includes obesity, elevated blood pressure, elevated fasting glucose, high triglycerides, and low high-density lipoprotein cholesterol. RESULTS: Using path analysis and including childhood adversity severity and depressive symptoms in the model, both Adult Attachment Interview coherence and unresolved trauma/loss were directly linked to the number of MetS criteria (r = 0.186 and r = 0.170, respectively). Idealization was indirectly linked to MetS through poor diet (r = 0.183). The final model explained 21% of the variance in scores for the number of MetS criteria met. CONCLUSIONS: Insecure adult attachment is associated with increased risk of MetS.

The influence of speaker and listener variables on intelligibility of dysarthric speech.

UNLABELLED: This study compared changes in speech clarity as a function of speaking context. It is well documented that words produced in sentence contexts yield higher intelligibility than words in isolation for speakers with mild to moderate dysarthria. To tease apart the effect of speaker and listener variables, the current study aimed to quantify differences in word intelligibility by speaking task. Eighteen speakers with dysarthria produced a set of 25 words in isolation and within the context of a sentence. Eighteen listeners heard a randomized sample of the isolated productions, single words extracted from the sentences, and the full unaltered sentences. Listeners transcribed what they heard and rated their confidence. Words produced in isolation were just as intelligible as words produced in sentence context, both of which were more intelligible than extracted words. In other words, speakers reduced articulatory clarity in sentence production compared to isolated productions; listeners were able to cope with this reduction in clarity when they had access to contextual information but not when these cues were removed in the extracted condition. These findings are consistent with Lindblom's hypo-hyperarticulation theory in that adults with dysarthria appear to be modulating articulatory precision based on listener/task variables. This work has implications for clinical practice in that isolated word and sentence production tasks yielded equivalent intelligibility findings. LEARNING OUTCOMES: Readers will recognize that speech intelligibility is influenced by speaker and listener variables and thus the choice of speaking and listening task may yield different results. Commonly held clinical belief is that sentence production tasks yield inflated intelligibility scores but we did not find that in this sample. Findings also indicate that speakers with dysarthria may modulate articulatory clarity in response to listener needs which should be considered in treatment planning.

Early life adversity is associated with elevated levels of circulating leptin, irisin, and decreased levels of adiponectin in midlife adults.

CONTEXT: Early-life adversity, defined as physical, emotional, or sexual abuse and neglect before 18 years of age, is associated with metabolic syndrome, obesity, and type 2 diabetes mellitus in adult life. However, the underlying mechanism is not fully understood, and whether adipomyokines are associated with early-life adversity independent of other factors such as body mass index, psychosocial risks, and health behaviors is not known. OBJECTIVES: The objective of the study was to evaluate the association between early-life adversity and circulating the levels of the adipomyokines such as leptin, adiponectin, and irisin and the inflammatory marker, C-reactive protein (CRP). DESIGN/SUBJECTS/SETTING: This study was a cross-sectional study of 95 adults at a university-based research center. We collected venous blood from participants and analyzed serum for leptin, adiponectin, irisin, and CRP. RESULTS: Circulating leptin, irisin, and CRP levels were significantly higher in the highest adversity tertile group compared with low and middle tertile groups (P < .001 for leptin, P = .01 for irisin, and P = .02 for CRP). Adiponectin levels were lower in the highest tertile group compared with the low and middle tertile groups (P = .03). After adjusting for demographic variables, physical activity, diet, current mental health, and body mass index, the associations between early-life adversity leptin, irisin, and did not change. However, adiponectin and CRP levels were no longer significantly related to early life adversity. CONCLUSION: Early-life adversity is directly associated with elevated circulating leptin and irisin, and indirectly associated with elevated CRP and decreased adiponectin. These findings suggest that these adipomyokines may play a role in the pathogenesis of metabolic abnormality in a population with significant early life adversity.

Detailed assessments of childhood adversity enhance prediction of central obesity independent of gender, race, adult psychosocial risk and health behaviors.

OBJECTIVE: This study examined whether a novel indicator of overall childhood adversity, incorporating number of adversities, severity, and chronicity, predicted central obesity beyond contributions of "modifiable" risk factors including psychosocial characteristics and health behaviors in a diverse sample of midlife adults. The study also examined whether the overall adversity score (number of adversities × severity × chronicity) better predicted obesity compared to cumulative adversity (number of adversities), a more traditional assessment of childhood adversity. MATERIALS/METHODS: 210 Black/African Americans and White/European Americans, mean age=45.8; ±3.3 years, were studied cross-sectionally. Regression analysis examined overall childhood adversity as a direct, non-modifiable risk factor for central obesity (waist-hip ratio) and body mass index (BMI), with and without adjustment for established adult psychosocial risk factors (education, employment, social functioning) and heath behavior risk factors (smoking, drinking, diet, exercise). RESULTS: Overall childhood adversity was an independent significant predictor of central obesity, and the relations between psychosocial and health risk factors and central obesity were not significant when overall adversity was in the model. Overall adversity was not a statistically significant predictor of BMI. CONCLUSIONS: Overall childhood adversity, incorporating severity and chronicity and cumulative scores, predicts central obesity beyond more contemporaneous risk factors often considered modifiable. This is consistent with early dysregulation of metabolic functioning. Findings can inform practitioners interested in the impact of childhood adversity and personalizing treatment approaches of obesity within high-risk populations. Prevention/intervention research is necessary to discover and address the underlying causes and impact of childhood adversity on metabolic functioning.
