The association between stress and cardiovascular disease (CVD) risk is becoming established. A mechanistic link clarifying the intermediate steps between the experience of stress and the development of CVD would support this association. We sought to examine the role of perceived stress as a factor associated with disturbed sleep with the goal of providing an explanation for the stress-CVD connection. We performed a cross-sectional analysis of data recorded by subjects at entry to our CVD prevention program. Data collection included questionnaire surveys, anthropometrics, and a CVD-relevant laboratory panel. Of 350 consecutively enrolled subjects (mean age 54.4 ± 12.4 [SD] years, 138 men, 39%), 165 (47%) scored above the mean for stress measures. These high-stress subjects displayed an increased cardiovascular risk profile including elevated body mass index (mean ± SD 31.1 ± 5.9 vs. 29.0 ± 5.9, r(s) = 0.175), increased waist circumference (102 ± 17 cm vs. 98 ± 14, r(s) = 0.135), and elevated high-sensitivity serum C-reactive protein (0.384 mg/dl vs. 0.356, r(s) = 0.109). High-stress subjects also demonstrated greater daytime sleepiness (Epworth Sleepiness Scale: 10.4 ± 5.0 vs. 7.8 ± 4.8, r(s) < 0.316), greater fatigue (fatigue scale: 5.4 ± 2.2 vs. 3.4 ± 2.4, r(s) = 0.484), poorer sleep quality (Pittsburgh Sleep Quality Index: 8.5 ± 4.4 vs. 5.9 ± 4.0, r(s) = 0.416), and shorter sleep duration (20 min less/24 h, r(s) = negative 0.177) with a higher risk for sleep apnea (60% at high risk vs. 40%, p = 0.003) than low-stress subjects. High stress was associated with significant disturbances in sleep duration and sleep quality. Stress levels also correlated with daytime consequences of disturbed sleep. The stress-sleep connection may be an important mechanistic mediator of the association between stress and CVD. 相似文献

We explore different ways in which the human visual system can adapt for perceiving and categorizing the environment. There are various accounts of supervised (categorical) and unsupervised perceptual learning, and different perspectives on the functional relationship between perception and categorization. We suggest that common experimental designs are insufficient to differentiate between hypothesized perceptual learning mechanisms and reveal their possible interplay. We propose a relatively underutilized way of studying potential categorical effects on perception, and we test the predictions of different perceptual learning models using a two-dimensional, interleaved categorization-plus-reconstruction task. We find evidence that the human visual system adapts its encodings to the feature structure of the environment, uses categorical expectations for robust reconstruction, allocates encoding resources with respect to categorization utility, and adapts to prevent miscategorizations. 相似文献

This study aimed at investigating intentional and non‐intentional situations eliciting shame and guilt in relation to children's involvement in bullying, victimization and prosocial behaviour. We used the contextual model designed by Olthof, Schouten, Kuiper, Stegge, and Jennekens‐Schinkel (2000) according to which certain situations elicit more shame than guilt (‘shame‐only’, SO), whereas others elicit both guilt and shame (‘shame‐and‐guilt’, SAG). Besides these, four new scenarios were added (2 SO and 2 SAG) in which the protagonist was alternatively the perpetrator or the receiver of harm. Participants were 121 children aged 9–11, who filled in the self‐report Shame and Guilt Questionnaire, and a peer nomination survey to investigate the roles of bully, victim, prosocial and not involved. Results showed that in SAG situations, perpetrated‐harm situations elicited more guilt than neutral situations; while in SO situations, neutral situations elicited more shame than received‐harm situations. In SAG situations, prosocial children reported feeling more ashamed and guilty than bullies and not‐involved children, while in SO situations, victims scored higher on shame than not‐involved children. Results are discussed considering the contextual model employed and the relationship between emotions and behaviours. 相似文献
