Note: Sex, residence, and BMI were encoded as dummy variables. The reference category for sex is female. The reference category for residence is “countryside,” where Residence 1 represents “city,” and Residence 2 represents “town.” The reference category for BMI is “normal weight,” where BMI 1 represents “underweight” and BMI 2 represents “overweight or obese"
