As you work on your poster zoom in and out to the level that is more comfortable to you.
Go to VIEW > ZOOM.
Start designing your poster by adding the title, the names of the authors, and the affiliated institutions. You can type or paste text into the provided boxes. The template will automatically adjust the size of your text to fit the title box. You can manually override this feature and change the size of your text.
T I P : The font size of your title should be bigger than your name(s) and institution name(s).
Most often, logos are added on each side of the title. You can insert a logo by dragging and dropping it from your desktop, copy and paste or by going to INSERT > PICTURES. Logos taken from web sites are likely to be low quality when printed. Zoom it at 100% to see what the logo will look like on the final poster and make any necessary adjustments.
T I P : See if your school’s logo is available on our free poster templates page.
You can add images by dragging and dropping from your desktop, copy and paste, or by going to INSERT > PICTURES. Resize images proportionally by holding down the SHIFT key and dragging one of the corner handles. For a professional-looking poster, do not distort your images by enlarging them disproportionally.

There is a dose-dependent relationship between obesity and stillbirth 1-3 which is most evident in the late third trimester 1 .
An improved understanding of the effect of maternal obesity on fetal growth velocity may shed light on the pathophysiology behind the association between obesity and stillbirth.
GOAL: to establish the pattern of fetal growth throughout gestation among obese women based on the weight of their infants at delivery in comparison to the normal growth curve.
Retrospective cohort study.
Birth data obtained from the Texas Vital Records
Database from 2006-2011.
1,849,773 births were used in analysis after exclusion criteria were applied
Linear regression used to assess the rate of fetal growth throughout gestation.
% of large and small for gestational age (LGA and
SGA) deliveries for each Body Mass Index (BMI) class at each gestational week was compared to those of non-obese women.
Logistic regression was used to obtain the adjusted odds ratio for deliveries of LGA and SGA infants within each BMI class.
STATA 12 was used for statistical analyses

- Birth weight differs throughout gestation in infants born to overweight and obese women vs. those of normal BMI.
- This is most apparent at 37 weeks where infants born to Class III obese women are 206g larger than those born to a woman with a normal BMI.
- During 32-37 weeks gestation, the mean rate of fetal weight gain per week is accelerated [230g/wk (95% CI 222-238)] in
Class III obese women compared to patients with normal BMI [198g/wk (95% CI 197-200)].
- The increased fetal weight gain is followed by a decline in the rate of growth in the Class III Obese at late term.
- This pattern of rapid acceleration then deceleration results in a parallel increase in LGA infants among obese women; OR is 2.62 (95% CI 2.54-2.71) in Class III obese from 36-39 weeks gestation.
- An inverse pattern is observed for deliveries of SGA infants.
