P08.10: Embryonic growth and birthweight: a correlation study

Abstract

Poster discussion hub abstracts in NICU, despite neonatal weight the behaviour was as child with restriction. Conclusions:The studies should be focussed on the more accurate interpretation of the fetal growth in maternal obesity and accelerate maternal weight growth. In obese women and in women with gestational diabetes -even in the well-controlled cases, interpretation of the fetal growth curves should be interpreted with caution in estimated fetal well-being. The present study is still ongoing, and hope to find an algorithm to asses more accurate the risks. P08.09The influence of cigarette smoking and dietary habits on first trimester growth rate and embryonic heart rate Objectives: The aim of this study was to evaluate the effects of cigarette smoking and commonly consumed foods/drinks on the first trimester growth and embryonic heart rate. Methods: A prospective study from Feb 2013 -June 2015. Women recruited in the first trimester underwent two ultrasound scans; both the Crown-rump length (CRL) and the embryonic heart rate (EHR) were recorded. Each woman answered a standardised questionnaire which recorded smoking history, consumption of coffee, hot chocolate, tea, soft drinks, sweets (chocolate, candy bars and toffee) and curry. Consumption of food was calculated by multiplying the consumption frequency by the portion size. Results: 700 first trimester women were approached and a total of 378 women were recruited: 244 non-smokers, 58 smokers, 50 ex-smokers or quit in early pregnancy and 26 passive smokers. Smoking habits did not influence the CRL growth. There was a significant correlation between coffee/hot chocolate consumption and the initial CRL value. A negative correlation was noted between the EHR and curry consumption (R=-0.133, p-value=0.009), coffee consumption (R=-0.11, p-value=0.02), hot chocolate intake (R=-0.22, p-value<0.0001), and sweets (R=-0.1, p-value=0.04). Tea intake was positively correlated with the EHR (R=0.16, P=0.002). The CRL growth rate was inversely correlated with coffee (R=-0.11) and hot chocolate (R=-0.14) consumption. Multivariate analysis showed that increasing consumption of coffee and hot chocolate was associated with lower EHR. Consumption of tea correlated with increased EHR (p-value<0.05). Increasing consumption of coffee and hot chocolate was associated with a lower CRL growth rate. Conclusions: Our findings suggest that first trimester CRL growth rates and the EHR may be influenced by a variety of commonly consumed foods and drinks. The influence of these on the developing fetus beyond the first trimester requires further studies. Cigarette smoking was associated with lower EHR but did not influence the CRL growth. Department of Obstetrics and Gynecology, Universidad de los Andes, Santiago, ChileObjectives: Intrinsic/idiopathic factors are considered to be responsible of fetal growth. This could be detected even in early pregnancy. Also, variation in CRL increase has been demonstrated in daily practice. The objective was to evaluate if first trimester growth variat...
