OBJECTIVE Compared to normal weight adolescents, obese adolescents have lower serum omega-3 (n-3) polyunsaturated fatty acid (PUFA) concentrations, augmented inflammatory activity and endothelial dysfunction. We wanted to assess whether n-3 supplementation increases the serum n-3 PUFA concentration, improves vascular function and morphology, and lowers(More)
A growing trend among clinical studies is the use of heart rate monitors (HRMs) for assessment of heart rate variability (HRV). These instruments offer a convenient alternative to traditional electrocardiographs (ECGs) for recording and processing of R–R data. Reports on the validity of such systems are, however, conflicting. This study aimed to assess the(More)
We constructed a test to assess stress in children and compared it with established measures of depression, anxiety, angel; disruptive behavior, and negative self-perception. A total of 181 children aged between 9 and 12 years were enrolled at various stages of the construction of a new short questionnaire; Stress in Children (SiC). Baseline data, completed(More)
OBJECTIVE We assessed the hypothesis that differences in day and night-time systolic blood pressure (SBP) and heart rate (HR) recordings were smaller in obese versus lean children and adolescents, and whether measurements obtained during a school week or during weekends or holidays influenced these nocturnal falls. We also wanted to determine whether the(More)
OBJECTIVE   Obese children present with various cardiovascular risk factors affecting their future health. In adults, cardiac autonomic function is a major risk factor, predicting cardiovascular morbidity and mortality. We hypothesized that obese children and adolescents had a lower cardiac vagal activity than lean subjects. We measured cardiac spontaneous(More)
Despite mounting reports about the negative effects of chronic occupational stress on cognitive and emotional functions, the underlying mechanisms are unknown. Recent findings from structural MRI raise the question whether this condition could be associated with a functional uncoupling of the limbic networks and an impaired modulation of emotional stress.(More)
BACKGROUND Insomnia-type sleep disturbances are frequent among patients suffering from stress-related exhaustion disorder. However, clinical observations indicate that a subgroup suffer from sleep lengths frequently exceeding 9 hours, coupled with great daytime sleepiness. AIMS The aim of the present study was to investigate differences in(More)
OBJECTIVE Males have higher coronary heart disease (CHD) lifetime risk and increased magnitude of atherosclerosis, compared with women. Using very high-resolution ultrasound, we have shown that the intima thickness (IT) of radial and dorsal pedal arteries, measured separately from the media thickness (MT), increases with age. We wanted to test whether there(More)
BACKGROUND Using new, very high-resolution ultrasound biomicroscopy, we examined the thickness of artificial layers of silicone and intima thickness (IT) of radial and anterior tibial arteries in healthy subjects and in patients with vascular disease. METHODS AND RESULTS Silicone layers of varying thicknesses and mesenteric artery specimens obtained from(More)
OBJECTIVE Limited data, especially from longitudinal studies, are available regarding vascular health assessment in childhood. In this study, we performed longitudinal and cross-sectional studies in healthy children and adolescents to investigate age- and sex-related differences in vascular functions and vascular response to mental stress.
