The p-values refer to the following tests:
Qchi-square of independence,
FFisher's exact, and
WWilcoxon Mann-Whitney for independent samples.BMI - body mass index. The BMI classifications (in kg/m2) were determined as follows (ABESO, 2009):
<18.5: low weight;
18.5 to 24.9: normal weight;
25 to 29.9: pre-obese and
≥30: obese
