GHGE, greenhouse gas emissions; BF, body fat; CRI, crowding index.
Diets in EHU12/24 study were ranked by GHGE (kg eCO2/1000 kcal/d) and divided into quintiles. Those in the lowest quintile of GHGE were defined as low-GHGE diets, whereas those in the top quintile were defined as high-GHGE diets.
Determined by χ2 test.
Survey results were weighted using the weighting coefficients provided by the UPV/EHU.
To facilitate the data analysis, parents’ educational levels were regrouped as: at least one of the parents university education or not.
To facilitate the data analysis, CRI was regrouped as: score greater than 1; less than or equal to 1.
