RESUMEN
Inadequate health literacy or numeracy and probable cognitive impairment influence patients' medical outcomes. The study purpose was to examine the prevalence of inadequate health literacy, inadequate health numeracy, and probable cognitive impairment among bariatric surgery candidates and examine associations with undergoing bariatric surgery. Patients (N = 314) completed measures assessing these constructs during a required pre-surgical psychological evaluation. Approximately 9.6%, 24.2%, and 29.5% of the sample had inadequate health literacy, inadequate health numeracy, and probable cognitive impairment, respectively. In univariate analyses, those with inadequate levels of health literacy, inadequate health numeracy, and probable cognitive impairment were less likely to undergo surgery. In a multivariate model, inadequate health literacy independently predicted a lower likelihood of undergoing bariatric surgery. Findings underscore the importance of assessing these factors.

BACKGROUND: To date only a few published studies have examined the effect of disorder-relevant stressors on heart rate variability (HRV) in participants meeting a clinical diagnosis of GAD, with conflicting results. The primary aim of this study was to determine if GAD is associated with lower HRV at rest, and whether vagal regulation during task varies by type (i.e., baseline, anticipation, imagery, or worry). METHODS: This study investigated resting cardiac vagal tone and vagal regulation in a sample of 40 participants with or without a validated diagnosis of generalized anxiety disorder (GAD). High-frequency heart rate variability (HF-HRV) was used to index cardiac vagal activity. RESULTS: GAD was associated with vagal withdrawal during both imagery and worry inductions, but no group differences in resting vagal tone or worry were observed. LIMITATIONS: Methodological limitations include inherent limits to generalizability of laboratory-based findings; specifically worry induction and cardiac reactivity to lab-based stressors. CONCLUSIONS: The results support the notion that GAD is associated with vagal withdrawal during active bouts of idiographic worry and imagery, and question the assumption that GAD is associated with low resting vagal tone. In light of polyvagal theory these findings provide additional support for the presence of emotion regulation deficits in GAD, and identify specific ANS processes that underlie GAD.
