(Excerto) La ricerca sociologica si colloca sempre in un hie et nunc e lo studio di cui parlen) nel mio intervento non sfugge a questa inconveniente. Come altri studi empirici sui rapporto tra giovani e media, questa lavoro e nato, innanzitutto, dagli interrogativi suscitati dai miei figli, quando erano ancora piccoli. Non posso escludere che quest' interesse sia una sorta di tentativo inconscio di placare Ia mia coscienza di fronte ai problemi che facevo fatica a risolvere ali'interno della mia famiglia. Permettetemi anche di soffermarmi brevemente sui mio paese, il Portogalla, e sulla sua realtii culturale e politica. Vorrei sottolineare che, in una prospettiva di lungo peri ado, alia maniera di Braude!, il mio ·paese ha ritrovato Ia democrazia moho recentemente, dopa mezzo secolo di oscurantismo e di repressione del pensiero e della partecipazione attiva dei cittadini alia vita sociale.

BACKGROUND: By contrast with other southern European people, north Portuguese population registers an especially high prevalence of hypertension and stroke incidence. We designed a cohort study to identify individuals presenting accelerated and premature arterial aging in the Portuguese population. METHOD: Pulse wave velocity (PWV) was measured in randomly sampled population dwellers aged 18-96 years from northern Portugal, and used as a marker of early vascular aging (EVA). Of the 3038 individuals enrolled, 2542 completed the evaluation. RESULTS: Mean PWV value for the entire population was 8.4?m/s (men: 8.6?m/s; women: 8.2?m/s; P?0.02). The individuals were classified with EVA if their PWV was at least 97.5th percentile of z-score for mean PWV values adjusted for age (using normal European reference values as comparators). The overall prevalence of EVA was 12.5%; 26.1% of individuals below 30 years presented this feature and 40.2% of individuals in that same age strata were placed above the 90th percentile of PWV; and 18.7% of the population exhibited PWV values above 10?m/s, with male predominance (17.2% of men aged 40-49 years had PWV?>?10?m/s). Logistic regression models indicated gender differences concerning the risk of developing large artery damage, with women having the same odds of PWV above 10?m/s 10 years later than men. CONCLUSION: The population PWV values were higher than expected in a low cardiovascular risk area (Portugal). High prevalence rates of EVA and noteworthy large artery damage in young ages were found.
