The 2007 PrISMA study surveyed 3,418 children aged 10-14 living in urban areas of Italy.

Notes on verification

Sample size (3,418), age range (10-14), and urban Italian setting are strongly corroborated across multiple peer-reviewed sources (Frigerio et al. 2006, 2009). The specific '2007' date is plausible as the fieldwork year (between the 2006 methods paper and 2009 results paper) but is not directly confirmed by any source found.
