COSI: Childhood Obesity Surveillance Initiative; NA: not applicable because the country did not use its own clothes adjustment weights; ND: not determined, because none of the children were classified into this category; SD: standard deviation. The weighted mean of the clothes adjustment weights for the entire country dataset was calculated by firstly multiplying the clothes adjustment weight used for each type of clothing by a country and the proportion that each type of clothing occurred in a dataset and secondly by adding up the weighted mean for each type of clothing. This answer option was selected when an examiner found it difficult to choose one of the four other predefined answer options for the clothes worn by a child. The country-specific clothes adjustment weights that were provided for all predefined types of clothing were applied to calculate the weighted mean of the clothes adjustment weights for the entire country dataset. The average non-country-specific clothes adjustment weights were applied for the four predefined answer options (“underwear only”: 0 grams, “gym clothes”: 130 grams, “light clothing”: 195 grams, and “heavy clothing”: 600 grams) and country-specific clothes adjustment weights for the option “other” (if applicable) to calculate the weighted mean of the clothes adjustment weights for the entire country dataset. #This country did not provide its own country-specific clothes adjustment weights; thus, the average non-country-specific adjustment weights were applied, based on the single country-specific adjustment weights provided by Bulgaria, Latvia, Lithuania, Malta, Norway, Portugal, and Sweden for each predefined type of clothing in round 1. Various adjustment weights, based on a description of the clothes worn, were used; hence, a range is indicated. All single country-specific clothes adjustment weights for a type of clothing (except those from Italy) were included in the calculation of these values. The interquartile range of the absolute change values of the countries is given. The mean (SD) of the absolute change values of the countries is given. |
