Ickovics, 2016 Randomized group-controlled clinical trial 1,148 (573) Adolescents aged 14-21, < 24 weeks of gestational age Less possibilities of having children with a small size for gestational age (<10th percentile) (11.0% vs 15.8%; OR 0.66; 95% IC 0.44-0.99)
Kennedy, 2011 Randomized clinical trial 322 (162) Military personnel over 18 years old, < 16 weeks of gestational age Six times more likely to receive better prenatal care. Greater satisfaction with their health care (p < 0.001). Higher average number of prenatal visits (10.31 visits vs. 8.56) and, of those in group prenatal care, only 12.9% had fewer than 9 visits vs. 46.7% of those in individual care p < 0.005, OR:5.92 IC 3.21-10.91)
