Outcomes were compared using multivariate analyses controlling for confounding variables.\\n\\nRESULTS: Compared to normoweight, overweight and obese women have greater risks of gestational diabetes mellitus (RR = 2.13 (95% CI: 1.52-2.98) and (RR = 2.85 (95% CI: 2.01-4.04), gestational hypertension (RR = 2.01 (95% CI: 1.27-3.19) and (RR = 4.79 (95% CI: 3.13-7.32) and preeclampsia (RR = 3.16 (95% CI: 1.12-8.91) and (RR = 8.80 (95% CI: 3.46-22.40). Obese women have also more frequently oligodramnios (RR = 2.02 (95% CI: 1.25-3.27), polyhydramnios. (RR = 1.76 (95% CI: 1.03-2.99), tearing (RR = 1.24 (95% CI: 1.05-1.46) and a lower risk of induced deliveries (RR = 0.83 (95% CI: 0.72-0.95). Both groups have more frequently caesarean section (RR = 1.36 (95% CI: 1.14-1.63) and (RR = 1.84 (95% CI: 1.53-2.22) and manual placenta extraction (RR = 1.65 (95% CI: 1.28-2.11) and (RR = 1.77 (95% CI: 1.35-2.33). Newborns from overweight and obese women have higher weight (p<0.001) and a greater risk of being macrosomic (RR = 2.00 (95% CI: 1.56-2.56) and (RR = 2.74 (95% CI: 2.12-3.54). Finally, neonates from obese mother have a higher risk of being admitted to special care units (RR = 1.34 (95% CI: 1.01-1.77). Apgar 1 min was significantly higher in newborns from normoweight mothers: 8.65 (95% CI: 8.62-8.69) than from overweight: 8.56 (95% CI: 8.50-8.61) or obese mothers: 8.48 (95% CI: 8.41-8.54).\\n\\nCONCLUSION: Obesity and overweight status at the beginning of pregnancy increase the adverse outcomes of the pregnancy. It is important to promote the normalization of bodyweight in those women who intend to get pregnant and to provide appropriate advice to the obese women of the risks of obesity at the start of the pregnancy.", "link"=>"http://www.mendeley.com/research/maternal-obesity-early-pregnancy-risk-adverse-outcomes-2", "reader_count"=>57, "reader_count_by_academic_status"=>{"Unspecified"=>1, "Professor > Associate Professor"=>1, "Student > Doctoral Student"=>3, "Researcher"=>3, "Student > Ph.
