La croissance fœtale physiologique : influence du mode de vie des femmes enceintes

Abstract : Introduction: Growth is a complex biological phenomenon involving many factors. Here, our focus is on the variability of physiological growth with much less work done in this area. This has led to the research question: « What is the influence of pregnant women's lifestyle on the growth of their fetus as measured during ultrasound and birth? ». Objective: To determine what elements of pregnant women's lifestyles were related to physiological fetal growth. Material and method : A retrospective multicentre study was conducted in 3 maternity between June and October 2019. This survey was conducted using a questionnaire distributed to patients and with a collection of data on medical records. It included 60 primiparous women who delivered at term (> 37 SA) a single fetus, were between 1.58 and 1.70 m tall, had a normal BMI, and were aged 20 to 35 years ; these women were not expected to have had a pathologic pregnancy or to have consumed toxins during the pregnancy. The fetal growth was compared according to several variables in women’s lifestyles. As the variables collected were not all measured at the same time (e.g. 31 SA vs 34 SA for the 3rd ultrasound), polynomial regression was used to construct the most suitable growth curve ; we then used the GEE analysis with a significance threshold defined by p < 0.05 to evaluate the significance of the different results. Results: Fetal growth may have been influenced by organic food and cosmetics, quality of sleep, level of education, and where pregnant women live. There is no evidence of a link between the foetal sex, diet, drinks consumed, physical activity, occupation and the pregnant woman's environment. Conclusion: This study allowed a global analysis of the maternal lifestyle and its influence on fetal growth with some significant results. Now, it would be interesting to carry out this study on a larger scale and with a more detailed description of the variables studied.
