^aChi square test for difference in weight status between genders in 20–39-year-old group (p < 0.001)
^bChi square test for difference in weight status between genders in 40–65-year-old group (p < 0.001)
^cChi square test for difference in weight status between genders in 65+ year-old group (p < 0.006)
^dBased on BMI (kg/m²) categorization: < 18.5 = underweight; 20–25 = normal weight; > 25–30 = overweight; > 30 = obese
^eStudy population ≥ 20 years of age; Chi square test for difference in weight status between age groups in total (p < .001) and per gender (p < .001)
