Exposition à la caféine durant la grossesse :
les facteurs prédictifs de la consommation et association aux issues indésirables de grossesse
BACKGROUND: Several studies have been conducted on the association between several adverse pregnancy outcomes and caffeine intake during pregnancy; but, no study has yet been conducted on the predictors of such exposure. However, a consideration of these factors would contribute in making nutritional recommendations in this regard more efficient. In addition, few studies had evaluated the risk of small for gestational age infants (SGA) compared to other adverse pregnancy outcomes.  OBJECTIVES: 1) To determine the frequency of caffeine consumption during pregnancy and its predictors, 2) Quantify the association between SGA outcome and this exposure.  METHODS: 3458 participants were randomly selected from the Quebec Pregnancy Registry (QPR) created by the linking of three administrative databases: RAMQ, MED-ECHO and ISQ. Statistical analyzes were used to examine predictors of the use and case-control study was conducted to quantify the risk of SGA associated with it.  RESULTS: 87.3% of participants consumed caffeine prior to pregnancy and 71.4% during. Maternal age, smoking, hypertension and hospitalizations before pregnancy are predictors of caffeine consumption during pregnancy. A 20% increase in SGA risk was observed [OR = 1.19, 95% CI (1.01 - 1.40)].  CONCLUSION: Caffeine consumption during pregnancy is common and safety of this use must be questioned. Our results suggest that caffeine consumption during pregnancy increases the risk of SGA.
