  1. NEAP net endogenous acid production, PRAL potential renal acid load, WC waist circumference, HC hip circumference, BMI body mass index; TBW total body water; FFM fat-free mass, WHR waist-to-hip ratio, WHtR waist-to-hip ratio, BAI body adiposity index
  2. *P values are calculated linear regression. The adjusted model is adjusted for age, gender, physical activity, socioeconomic status, and energy, protein, and fat intakes
