“…Of this, 12 studies assessed obesity based on body mass index (BMI), 9,28,36,43,45,56,65,71,72,76,79 ,83 and 35 studies used waist circumference for the assessment of obesity. 12,21,23,24,26,27,[33][34][35][38][39][40]42,44,47,48,[51][52][53][54][55][57][58][59][60][61][62][63][64]67,69,[73][74][75]82 The overall CKD risk related to higher BMI/waist circumference, as compared with lower BMI/waist circumference, was 1.22 (95% CI = 1.12-1.31), and was greater for higher values of waist circumference than BMI (Figure 3). In the stratified analysis by ethnicity, sex, and study type, the increased risk associated with higher values of BMI/waist circumference was significant in different subgroups.…”
