Table 2. Distribution of study participants based on follow-up visit and weight gain.

Maternal parameters		Total (n = 418)	Under-weight (n = 67)	Normal weight (n = 262)	Overweight (n = 77)	Obese (n = 12)	p value

WG (kg)
	1st–2nd trimester	5.38 ± 0.91	5.65 ± 0.76	5.77 ± 0.44	4.16 ± 0.68	3.21 ± 0.73	< 0.001*
	2nd–3rd trimester	4.27 ± 0.75	4.64 ± 0.40	4.50 ± 0.45	3.31 ± 0.89	3.28 ± 0.63	< 0.001*
	3rd trimester–delivery	3.27 ± 1.30	3.87 ± 1.35	3.42 ± 1.24	2.47 ± 1.01	1.85 ± 0.59	< 0.001*
GWG (kg)		12.93 ± 2.29	14.17 ± 1.45	13.70 ± 1.48	9.95 ± 1.85	8.35 ± 1.47	< 0.001*

The test of significance used to determine statistical difference among the groups was analysis of variance.

WG, weight gain; GWG, gestational weight gain.
