Question: Is fetal nuchal cord a risk factor for autism spectrum disorder (ASD)?
Finding: Five articles (1 cohort, 4 case-control; total 3,088 children) were included in the present meta-analysis. Fetal nuchal cord was not a risk factor for ASD (odds ratio, 1.11; 95% confidence interval, 0.66–1.57). There was homogeneity among studies that reported a risk of ASD (I2=0.0).
Meaning: Fetal nuchal cord is not a risk factor for ASD. |

Question: Have polycystic ovary syndrome (PCOS) increased risk of having an offspring with attention-deficit/hyperactivity disorder (ADHD)?
Finding: Six articles (3 cohort and 3 case-control studies; 401,413 total ADHD cases) met the study criteria. Maternal PCOS was associated with an increased risk of ADHD in the offspring based on odds ratio (OR) and relative ratio (RR) (OR, 1.42; 95% confidence interval [CI], 1.27–1.57) and (RR, 1.43; 95% CI, 1.35–1.51), respectively.
Meaning: Our study showed that maternal PCOS is a risk factor for ADHD. |
