Geographical distribution of the prevalence of overweight (including obesity) (1A) and obesity (1B) in children aged 6–9 years (sexes combined) of COSI Round 2 (2009/2010), based on WHO definitions
. Abbreviations: COSI, Childhood Obesity Surveillance Initiative; MKD, the former Yugoslav Republic of Macedonia; WHO, World Health Organization. ‡Prevalence estimates were based on the 2007 WHO recommended growth reference for school-age children and adolescents . Children with a body mass index-for-age Z-score < −5 or > +5 were excluded. Belgium represents Flanders only and Portugal represents all regions except Madeira. WHO European Member States are grouped into eight geographic subregions to facilitate comparative analysis and interpretation. None of the central Asian republics or the Commonwealth of Independent States participated in Round 2, and thus these two subregions are excluded from both figures. *MKD is the International Organization for Standardization (ISO) 3166–1 Alpha-3 country code for the former Yugoslav Republic of Macedonia.
