Mary stayed away for the first full trimester, thus avoiding pressure by family members and society at large to have an abortion, which may very well have been an option at the time.
Despite a punishing schedule of international engagements, Sellars finds time to teach one full trimester a year at the University of Los Angeles, overseeing two courses: "Art as moral action" and "Art as social action," both broad examinations of the social, moral and spiritual dimensions of the business of making art.
Personal exposures are often estimated at different terms, including the full gestation, trimesters, month after the pregnancy or before the time of delivery, etc.
Cluster 2 was peculiar as 61%% of the women did not have any prenatal care consumption ("Absence") for at least two full trimesters, although more heterogeneity was visible between sequences than in the other two clusters.
These associations were observed across the full range of first trimester fetal crown to rump length and not in the extremes only.
We tested for the effect of meteorological factors (ambient temperature, humidity, and atmospheric pressure, averaged over the full pregnancy and each trimester) on the birth outcomes of interest to decide whether adjustment was warranted; both linear and restricted cubic spline coding were considered.
However, attenuated ORs were observed for O3 during the first trimester and the full pregnancy period, and no significant association was found for PM2.5 in the first trimester.
However, the ORs for PM2.5 during the first trimester and the full pregnancy were attenuated, and no association was observed for PM2.5 during the second trimester in the co-pollutant model (OR = 1.02; 95% CI: 0.98, 1.07).
However, the ORs for PM2.5 during the first trimester and the full pregnancy attenuated after adjusting for O3, and no association was observed for PM2.5 during the second trimester in the co-pollutant model (OR = 1.02; 95% CI: 0.98, 1.07 compared with OR = 1.15; 95% CI: 1.10, 1.20 from the single-pollutant model).
We looked at these outcomes over the full pregnancy period and per trimester.
Exposures were calculated as daily concentrations averaged over each of the first two trimesters (trimester 1: 1–13 weeks; trimester 2: 14 26 weeks) and the full gestational period determined by gestational age and delivery date of each woman.
