	Gestational periods
SF-36 Scale	1st trimester (n = 100) (mean ± SEM)^d	2nd trimester (n = 97)(mean ± SEM)^d	3rd trimester (n = 106)(mean ± SEM)^d	P^e
Physical functioning	57.6 ± 1.6^a,b	61.4 (1.6)^a	54.9 (1.5)^b	0.022
Role–physical	46.7 ± 3.7^a	62.2 (3.7)^b	38.7 (3.6)^c	< 0.001
Bodily pain	45.4 ± 0.6	44.3 (0.6)	43.8 (0.6)	0.171
General health	45.8 ± 1.7^a	54.5 (1.7)^b	43.8 (1.6)^a	< 0.001
Vitality	51.0 ± 1.6^a	56.7 (1.6)^b	45.8 (1.5)^c	< 0.001
Social functioning	47.8 ± 1.8^a	57.5 (1.9)^b	41.5 (1.8)^c	< 0.001
Role–emotional	46.8 ± 3.7^a	63.3 (3.9)^b	45.4 (3.7)^a	0.002
Mental health	56.9 ± 1.7^a	61.9 (1.7)^b	50.0 (1.7)^c	< 0.001

^a,b,cThe groups not having the same letter in each row were significantly different from each other.

^dValues were adjusted according to the economic status, educational status, and total number of pregnancies (mean ± standard error).

^eThe P-values were calculated by using general linear model.
