  1. SD standard deviation, no. n/sample size, kg kilograms
  2. aIndependent t-test for continuous variables or chi-square test for categorical variables were used to help interpret meaningful differences between the groups.
  3. bNote that race/ethnicity data were not collected in respondents from France and Germany where regulations restrict collecting these data.
  4. Bold indicates significant differences between groups.
