Body mass index (BMI) classifications: normal weight (BMI 18.5–24.9 kg/m2); overweight (BMI 25.0–29.9 kg/m2); obese grade I (BMI 30.0–34.9 kg/m2); obese II (BMI 35.0–39.9 kg/m2); obese III (BMI ≥ 40.0 kg/m2); underweight (BMI < 18.5 kg/m2).
Normal body fat percentage (males: <27.5%; females: <39.9%); excess body fat percentage (males: ≥27.5%; females: ≥39.9%).
Physical activity guidelines based on the 2018 CDC recommendations of 450 metabolic equivalent minutes per week.
BMI, body mass index; CDC, Centers for Disease Control and Prevention; kg/m2, kilogram per square meter; <, less than; ≥, more than or equal to; n, number; %, percent; p, probability; SD, standard deviation; N/A, not applicable.
Fisher exact test used for analysis.
