In this study, we assessed whether the white-coat effect (difference between office and daytime blood pressure (BP)) is associated with nondipping (absence of BP decrease at night). Data were available in 371 individuals of African descent from 74 families selected from a population-based hypertension register in the Seychelles Islands and in 295 Caucasian individuals randomly selected from a population-based study in Switzerland. We used standard multiple linear regression in the Swiss data and generalized estimating equations to account for familial correlations in the Seychelles data. The prevalence of systolic and diastolic nondipping (<10% nocturnal BP decrease) and white-coat hypertension (WCH) was respectively 51, 46, and 4% in blacks and 33, 37, and 7% in whites. When white coat effect and nocturnal dipping were taken as continuous variables (mm Hg), systolic (SBP) and diastolic BP (DBP) dipping were associated inversely and independently with white-coat effect (P < 0.05) in both populations. Analogously, the difference between office and daytime heart rate was inversely associated with the difference between daytime and night-time heart rate in the two populations. These results did not change after adjustment for potential confounders. The white-coat effect is associated with BP nondipping. The similar associations between office-daytime values and daytime-night-time values for both BP and heart rate suggest that the sympathetic nervous system might play a role. Our findings also further stress the interest, for clinicians, of assessing the presence of a white-coat effect as a means to further identify patients at increased cardiovascular risk and guide treatment accordingly.

Depuis la promulgation de l'arrêt « Bosman  » en 1995, le nombre de joueurs expatriés recensés dans les principaux championnats européens a considérablement augmenté. Cet article montre que cette augmentation a surtout concerné les joueurs originaires d'Afrique et d'Amérique latine. Leur mobilité intervient dans un contexte très spéculatif au sein duquel de nombreux intermédiaires interagissent pour construire les canaux migratoires permettant aux joueurs de circuler à travers différents pays. Les trajectoires idéales - typiques de joueurs africains en Europe - permettent d'illustrer les logiques sociales, géographiques et économiques à la base de ces flux. Since the "Bosman" law in 1995, the number of expatriate players in the best European leagues has strongly increased. This paper shows that this increase has above all concerned players from Africa and South America. The mobility of these footballers occurs in a highly speculative context in which numerous intermediaries intervene to build up the migratory channels that allow players for circulating between many countries. The ideal-typical career paths of African footballers in Europe permit to illustrate the social, geographic and economic logics underlying flows.

L'histoire du football Rwanda commence avec la colonisation du pays. En une cinquantaine d'années, ce jeu sport d'origine anglaise, en intégrant une société agro-pastorale et guerrière, est devenu une pratique culturelle locale. Comprendre ce phénomène nécessite d'articuler l'ancrage colonial d'une activité cosmopolite aux [ré]inventions culturelles locales suscitées par son implantation. Ce texte vise à montrer comment un jeu de balle, en traversant une société en cours d'occidentalisation, a marqué l'édification d'une modernité guerrière reçue et façonnée par les joueurs de l'époque. En traversant les transpositions ludiques d'enjeux sociaux et politiques plus larges, on observe que cette pratique, tout en participant du procès de "civilisation" que s'administra l'institution coloniale, constitua l'un des fers de lance de la lutte pour l'émancipation.
