Adolescent overweight and obesity were strongly associated with ID mortality, especially of bacterial origin and among women.

Objective To investigate whether an association exists between deceleration and acceleration areas on continuous fetal cardiotocography (CTG) and neonatal encephalopathy (NE). Methods A single center, retrospective case–control study was conducted to compare CTG characteristics of low‐risk pregnancies (35 weeks of gestation or more), complicated by moderate to severe NE with two matched controls for every case. Controls were matched by gestational age and cord blood pH. We analyzed the intrapartum CTG recordings by calculation of the deceleration and acceleration areas and the ratio between the two. Results During the period between 2013 and 2019, we identified 95 cases of low‐risk pregnancies that were complicated by moderate to severe NE in our center. Thirty‐three (34.7%) deliveries were excluded, mostly because of an insufficient duration of the CTG recordings. The remaining 62 cases were matched with 123 controls. We found that NE was significantly associated with an increased total deceleration area, a decreased total acceleration area, and a lower acceleration‐to‐deceleration ratio. Conclusions NE was significantly associated with increased total deceleration area, decreased total acceleration area, and a lower acceleration‐to‐deceleration ratio, independent of cord blood pH. Development of a computerized real‐time analysis of fetal heart rate tracings may contribute to making these measurements a more valid clinical tool.
