COSI: Childhood Obesity Surveillance Initiative; ND: not determined because the country did not use this type of clothing in the questionnaire to describe the clothes worn by the child when anthropometric measures were taken.
Only children whose age fell within the country-specific targeted age group(s) were included.
This answer option was selected when an examiner found it difficult to choose one of the other four predefined answer options for the clothes worn by a child.
