TABLE 6.

Odds of exceeding NAM gestational weight gain (GWG) guidelines during pregnancy in intervention group vs usual care control group

Stage of pregnancy	Intervention Group N=89^a		Usual Care Control Group N=80^a		Odds Ratio (OR) (95% CI)
Stage of pregnancy	N exceeding/total N	Percentage exceeding	N exceeding/total N	Percentage exceeding	Odds Ratio (OR) (95% CI)
First trimester	36/86	41.9%	32/79	40.5%	1.06 (0.57, 1.97)
Second trimester	59/82	72.0%	53/78	67.9%	1.21 (0.62, 2.38)
Third trimester	65/82	79.3%	54/75	72.0%	1.49 (0.71, 3.10)
Total GWG^b	50/75	66.7%	36/66	54.5%	1.67 (0.84, 3.30)

Total Ns are lower at later time points due to pregnancy loss, pregnancies that were ongoing at time of final data collection, and missing data (see Table 3 for reasons for missing data);

Total GWG analyses only included those who had full term delivery (≥37 weeks).
