Are women in Singapore gaining weight appropriately during pregnancy: a prospective cohort study

Table 3 Rate of GWG (in kg/week) between scheduled visits with reference to IOM recommendations

Pre-pregnancy BMI groups	IOM recommendation of rate of GWG in 2nd and 3rd trimesters	GWG 1^a	GWG 2^b	GWG 3^c
Pre-pregnancy BMI groups	Mean (range) in kg/week	Mean in kg/week (with ref. to IOM recommendation)
Under Weight (N = 59)	0.51 (0.44–0.58)	0.38 (<R)	0.54 (WR)	0.50 (WR)
Normal Weight (N = 414)	0.42 (0.35–0.50)	0.33 (<R)	0.55 (>R)	0.47 (WR)
Over Weight (N = 173)	0.28 (0.23–0.33)	0.31 (WR)	0.47 (>R)	0.46 (>R)
Obese (N = 78)	0.22 (0.17–0.27)	0.19 (WR)	0.40 (>R)	0.46 (>R)
P-value comparing GWG among BMI groups		<.0001	<.0001	0.816

Visit 1 (11–14 Week); Visit 2 (18–24 Week); Visit 3 (28–32 Week); Visit 4 (34 Week Onwards)
Definitions: <R: weight Gain less than recommended range; WR: weight gain within recommended range;>R: weight gain more than recommended range
^aGWG 1 = rate of gestational weight gain between scheduled Visit 2 and Visit 1
^bGWG 2 = rate of gestational weight gain between scheduled Visit 3 and Visit 2
^cGWG 3 = rate of gestational weight gain between scheduled Visit 4 and Visit 3
