Sentence examples for trimester fell from inspiring English sources

The second study reported that DWTD was positively associated with the risk of preterm birth in mothers living in low SES neighbourhoods whose third trimester fell during winter, and in mothers living in moderate SES neighbourhoods [ 23].

In addition, an elevated risk was observed for women whose third trimester fell during the fall/winter months (RR, 1.39; 95% CI, 1.16 1.67); this is probably due to the more stagnant air conditions during the winter period.

Examining the influence of season, we found elevated risks primarily for women whose third trimester fell during fall/winter months (OR term LBW) = 1.39; 95% CI, 1.16-1.67; OR(preterm and LBW) = 1.24; 95% CI = 1.03-1.48; RR(all preterm) = 1.15; 95% CI, 1.05-1.26), and exposure-response relations were stronger for all outcomes.

The weighting was based on the proportion of the trimester falling into each quarterly period.

For PM2.5 the estimated exposures in adjacent trimesters (the 1st and 2nd; the 2nd and 3rd) are weakly correlated (r = 0.23 to 0.32), but those for the 1st and 3rd trimesters are more strongly correlated (r = 0.73 to 0.76), likely because the 1st and 3rd trimesters fall close to peaks/troughs of the bi-annual cycle of PM2.5's temporal pattern.

Infants with SO(2) second trimester exposures falling within the 25 and < 50th (AOR 1.21; CI 1.07,1.37), the 50 to < 75th (AOR 1.20; CI 1.08,1.35), and the 75 to < 95th (AOR 1.21; CI 1.03,1.43) percentiles were also at increased risk for term LBW when compared to those in the reference category (< 25th percentile).

Wilhelm and Ritz [ 16] noted that the effect of residential proximity to heavy traffic roadways on preterm birth was greater for those whose third trimester of pregnancy fell in autumn/winter.

Additionally, prenatal visits during the first semester of pregnancy increased by 8%§ among PROGRESA beneficiaries and initial visits in the second and third trimesters of pregnancy fell, a change that is recognised to improve the health of pregnant women and their infants (Skoufias, 2005).

If more than one address fell into a trimester, we chose the address where the subjects had spent the most time.

These losses fell within the first trimester, when most miscarriages occur.

In two pregnancies we have serial anti-HPA-1a antibody level measurements starting in the first trimester, and in both these pregnancies the anti-HPA-1a antibody levels fell from the first to the third trimester.
