Table 1.

Descriptive statistics for the whole set of variables considered in this study at wave 1 for the entire dataset (cohort 1, $N=4864$ ) and the merged dataset (cohort 2, N = 3890). The first part of the table gives minimum and maximum values, and mean and SD for each continuous variable. The second part shows ordinal or nominal variables and their frequency in percentage.
