Adjusted predicted probabilities for 4 adverse birth outcomes among obesity class 1 women (n = 3254). The sample size in each weight (Wt)-gain category was as follows: <0%, n = 111; 0% to 35%, n = 144; 35% to <77%, n = 203; 77% to 140%, n = 443; 141% to <211%, n = 813; 211% to <281%, n = 733; 281% to <352%, n = 430; and ≥352%, n = 377. The following factors were held constant: non-Hispanic white race-ethnicity, nulliparous, nonsmoker, >12 y education, and height = 64 in. SGA, small-for-gestational-age; LGA, large-for-gestational-age; iPTB <37, medically indicated preterm birth at <37 wk gestation; sPTB <37, spontaneous preterm birth at <37 wk gestation; IOM, Institute of Medicine.
