Weight status categories: (i) normal weight (BMI ≥18 kg/m² but <25 kg/m²); (ii) overweight (BMI ≥25 kg/m² but <30 kg/m²); (iii) class I obesity (BMI ≥30 kg/m² but <35 kg/m²); and (iv) class II and III obesity (BMI ≥35 kg/m²), were computed using current standards (4,28,29).

OR, odds ratio; RG, reference group.
