BMI: body mass index; BMI/: BMI-for-age; COSI: Childhood Obesity Surveillance Initiative; NA: not applicable because the country did not use its own clothes adjustment weights; : weight-for-age. Only children whose age fell within the country-specific targeted age group(s) were included (see Table 1). Body weight was adjusted for the clothes worn when measured using country-specific adjustment weights for all four predefined types of clothing and the clothing answer option “other.” Body weight was adjusted for the clothes worn when measured using the average non-country-specific adjustment weights for the four predefined types of clothing “underwear only,” “gym clothes,” “light clothing,” and “heavy clothing,” and country-specific adjustment weights for the clothing answer option “other.”
