Mid-upper arm circumference in pregnant women and birth weight in newborns as substitute for skinfold thickness: findings from the MAASTHI cohort study, India

Table 4 Cut-offs for different anthropometric measures that correspond to total skinfold thickness cut-off (85th percentile) for children at birth - determined by different methods of ROC curve analysis. [N = 2432]

Anthropometric measure	Cut-off corresponding to 85th percentile of total skinfold thickness from different methods
Anthropometric measure	Youden’s J statistic**	Minimized distance to (0, 1) point in the ROC curve	Sensitivity-specificity equality
Bodyweight (kg)	3.45	3.40	3.26
Head circumference (Cm)	35.00	34.70	34.60
Chest circumference (Cm)	33.70	33.70	33.40
Waist circumference (Cm)	31.70	32.40	32.40
Hip circumference (Cm)	30.30	30.30	30.50
Mid-upper arm circumference (Cm)	10.30	10.30	10.30
BMI (kg/m²)	13.22	12.87	12.88

^{** In case of discrepancy between cut−offs determined by different methods, the cut−off obtained via Youden’s J statistic was considered as standard}
