Food habits and sport activity during adolescence: differences between athletic and non-athletic teenagers in Switzerland.

OBJECTIVE: To describe food habits and dietary intakes of athletic and non-athletic adolescents in Switzerland. SETTING: College, high schools and professional centers in the Swiss canton of Vaud. METHOD: A total of 3,540 subjects aged 9-19 y answered a self-reported anonymous questionnaire to assess lifestyles, physical plus sports activity and food habits. Within this sample, a subgroup of 246 subjects aged 11-15 also participated in an in-depth ancillary study including a 3 day dietary record completed by an interview with a dietician. RESULTS: More boys than girls reported engaging in regular sports activities (P<0.001). Adolescent food habits are quite traditional: up to 15 y, most of the respondents have a breakfast and eat at least two hot meals a day, the percentages decreasing thereafter. Snacking is widespread among adolescents (60-80% in the morning, 80-90% in the afternoon). Food habits among athletic adolescents are healthier and also are perceived as such in a higher proportion. Among athletic adolescents, consumption frequency is higher for dairy products and ready to eat (RTE) cereals, for fruit, fruit juices and salad (P<0.05 at least). Thus the athletic adolescent's food brings more micronutrients than the diet of their non-athletic counterparts. Within the subgroup (ancillary study), mean energy intake corresponds to requirements for age/gender group. CONCLUSIONS: Athletic adolescents display healthier food habits than non-athletic adolescents: this result supports the idea that healthy behavior tends to cluster and suggests that prevention programs among this age group should target simultaneously both sports activity and food habits.

Le sport, un enjeu de santé publique ?

Les bénéfices pour la santé d'une activité physique régulière sont de mieux en mieux établis et s'appliquent notamment à des pathologies aussi diverses que l'infarctus du myocarde ou certains cancers. Or, deux tiers de la population suisse rapportent une pratique en activité physique inférieure aux recommandations minimales pour la santé. On estime en Suisse que la sédentarité est annuellement responsable de 2,1 millions de cas de maladie, de 2900 décès et de 2,4 milliards de francs de coûts liés aux traitements.

Superior vena cava syndrome due to chronic granulomatous mediastinitis.

We report a case of superior vena cava syndrome developing progressively over twenty years in a 48-year-old Venezuelan woman. The investigations revealed a locoregional etiology for the vena cava obstruction, namely a granulomatous mediastinitis probably secondary to histoplasmosis. We discuss the etiology, the clinical features, the natural course, and the therapy of chronic mediastinitis.

Inferior vena cava syndrome due to Echinococcus multilocularis.

Alveolar echinococcosis is an invasive, tumor-like zoonosis, accidentally transmitted to humans. We present a case of recurrent inferior vena cava (IVC) syndrome due to alveolar echinococcosis and strongly suspected on transthoracic echocardiographic examination.

The determinants of sport participation in Switzerland

This paper aims at investigating the socio-cultural factors that affect leisure-time sport participation in Switzerland. Data drawn from 8 waves of the Swiss Household Panel is used to evaluate a probit model with random effects, that takes into account the socioeconomic and demographic characteristics of the respondents. In line with existing literature, findings from the multivariate analysis show inequalities in sport involvement in Switzerland. These are significantly related to age, income, education, citizenship and cultural aspects. Appropriate and targeted policies promoting participation in sports among the community can be found on the basis of the critical modifiers in the model and their impact.
