Parameter estimate for non-transformed PCB measure (adjusted: maternal race, age, smoking status and BMI, infant sex, length of gestation (centered), quadratic length of gestation (centered), laboratory and natural log-transformed serum triglycerides and cholesterol).
Parameter estimate for non-transformed PCB measure (adjusted: p,p′-DDE, maternal race, age, smoking status and BMI, infant sex, length of gestation (centered), quadratic length of gestation (centered), laboratory and natural log-transformed serum triglycerides and cholesterol).
We examined whether breast cancer risk differed between women who had different length of gestation in their first pregnancy.
Fetal exposure to PCBs may result in adverse pregnancy outcomes such as decreased length of gestation and decreased birth weight.
Glynn et al. [ 21] found that stress in early pregnancy was related to shorter length of gestation.
Given that the association of Apgar score with cerebral palsy did not seem to be confounded by length of gestation, and because we had incomplete data on length of gestation, we only used birth weight in the final data analyses.
Postdates pregnancy (≥294 days or 42+0 weeks), length of gestation and likelihood of spontaneous onset of labour at term.
Third, we will examine the relationship between EPA and DHA and standard pregnancy outcomes, including birth weight and length of gestation.
Length of gestation was collected from linked hospital maternity records.
The medical history of the mother during pregnancy, the type of delivery and the length of gestation were recorded.
