WHO growth indicators of infants at sixth month postpartum.

Indicator	Urban control (n = 15)	Urban supplemented (n = 15)	Rural control (n = 15)	Rural supplemented (n = 15)	p-value
Weight-for-age Z-score (WAZ)	−0.42 ± 0.68	0.18 ± 0.61	−0.71 ± 0.74	−0.05 ± 0.65	0.032*
Length-for-age Z-score (LAZ)	−0.58 ± 0.72	0.02 ± 0.67	−0.89 ± 0.81	−0.22 ± 0.69	0.028*
Weight-for-length Z-score (WLZ)	−0.18 ± 0.64	0.41 ± 0.58	−0.36 ± 0.69	0.20 ± 0.60	0.041*
Conditional weight gain score	−0.12 ± 0.58	0.48 ± 0.62	−0.25 ± 0.63	0.35 ± 0.57	0.036*

Classification of conditional weight gain
Category	Urban control n (%)	Urban supplemented n (%)	Rural control n (%)	Rural supplemented n (%)
Slow weight gain (< −0.67 SD)	3 (20.0)	1 (6.7)	4 (26.7)	2 (13.3)
Normal weight gain (−0.67 to 0.67 SD)	10 (66.7)	12 (80.0)	9 (60.0)	11 (73.3)
Rapid weight gain (> 0.67 SD)	2 (13.3)	2 (13.3)	2 (13.3)	2 (13.3)

Values are expressed as mean ± standard deviation (SD) (n = 15 infants per group). Weight-for-age Z-score (WAZ), length-for-age Z-score (LAZ), and weight-for-length Z-score (WLZ) were evaluated using World Health Organization (WHO) Child Growth Standards. Conditional weight gain was classified as slow weight gain (SWG; < −0.67 SD), normal weight gain (NWG; −0.67 to 0.67 SD), and rapid weight gain (RWG; > 0.67 SD). Group comparisons were performed using one-way analysis of variance (ANOVA) followed by Tukey’s post hoc test. Statistical significance was established at p < 0.05. *p < 0.05.
