Le donne sovrappeso o obese nel mondo sono 375 milioni, mentre gli uomini 266. Questi dati emergono da uno studio sul "body mass index", a cui hanno preso parte più di 700 ricercatori, tra cui esperti dell'Università di Zurigo. La ricerca è stata pubblicata oggi, venerdì, sulla rivista "The Lancet".
I risultati mostrano che il peso medio della popolazione è aumentato di 1,5 chilogrammi ogni dieci anni negli ultimi quattro decenni. In Svizzera, per contro, tale evoluzione è risultata più lenta. Il Giappone inoltre è il paese, tra quelli sviluppati, in cui gli abitanti hanno il più basso indice di massa corporea, mentre negli Stati Uniti vi è il maggior numero di persone obese.
La situazione opposta, ossia le persone al di sotto del peso ideale, tocca ancora il 10% della popolazione mondiale, ma dal 1975 la percentuale riguardante questa categoria è diminuita di cinque punti percentuali sia per le donne (dal 15 al 10%) che per gli uomini (dal 14 al 9%).
