OBJECTIVE We studied in European adolescents (i) the association between cardiorespiratory fitness and ideal cardiovascular health as defined by the American Heart Association and (ii) whether there is a cardiorespiratory fitness threshold associated with a more favourable cardiovascular health profile. METHODS Participants included 510 (n=259 girls)(More)
OBJECTIVE Inadequate intakes of micronutrients in elderly negatively affect the nutritional status. Zinc is an essential micronutrient in the elderly, especially in relation to its impact on immune function, bone mass, cognitive function and oxidative stress. However, data are lacking on zinc intake and status during normal ageing. In this study, we(More)
OBJECTIVE We aimed to examine the association between adolescents' sleep time and a cardiometabolic risk score. A second aim was to examine associations between sleep time and individual cardiometabolic risk factors. METHODS Adolescents (N=699; ages, 12.5-17.5 years) participating in the HELENA (Healthy Lifestyle in Europe by Nutrition in Adolescence)(More)
This report aims (1) to examine the association between seasonality and physical activity (PA) and sedentary time in European adolescents and (2) to investigate whether this association was influenced by geographical location (Central-North versus South of Europe), which implies more or less extreme weather and daylight hours. Valid data on PA, sedentary(More)
OBJECTIVE To examine the reliability of a set of health-related physical fitness tests used in the European Union-funded Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) Study on lifestyle and nutrition among adolescents. DESIGN A set of physical fitness tests was performed twice in a study sample, 2 weeks apart, by the same researchers.(More)
Overweight and obesity are associated with low grade of inflammation and chronic inflammatory response characterized by abnormal production and activation of some pro-inflammatory signalling pathways. Taking into account that obesity is the direct result of an imbalance between energy intake and energy expenditure, the nutritional factors in the diet, with(More)
A randomised double-blind placebo-controlled design was employed to investigate the effects of Zn supplementation on cognitive function in 387 healthy adults aged 55-87 years. Several measures of visual memory, working memory, attention and reaction time were obtained using the Cambridge Automated Neuropsychological Test Battery at baseline and then after 3(More)
OBJECTIVE The aim of the study was to investigate whether zinc supplementation affects antioxidant status in European middle-aged and elderly people. DESIGN Multicentre prospective intervention study, randomized, double-blind, placebo-control. SETTING France (Clermont-Ferrand/Theix, and Grenoble), Italy (Rome), Northern Ireland (Coleraine). SUBJECTS A(More)
BACKGROUND The purpose of this study was to evaluate the overall diet quality effects, mainly on antioxidant nutritional status and some cytokines related to the cellular immune response as well as oxidative stress in a healthy Italian population group. METHODS An observational study was conducted on 131 healthy free-living subjects. Dietary intake was(More)
OBJECTIVES The aim of this work was to evaluate the effect of long term supplementation with two moderate dose of Zn on plasma and cellular red-ox status markers in elderly volunteers. DESIGN, SETTING AND SUBJECTS In a double blind study 108 healthy volunteers, aged 70-85 years, were enrolled. They were randomly divided in 3 groups of treatment, receiving(More)
