1. Objectifs

Intentions :
«The general objective of the current study was to evaluate the association between eating behaviours and GWG [gestational weight gain] in a population of healthy pregnant women while considering pre-pregnancy BMI [body mass index]. More specifically, the first specific objective was to examine changes in eating behaviours across trimesters. […] The second specific objective was to characterize how eating behaviours varied according to total GWG group and BMI categories.» (p. 55)

Questions/Hypothèses :
For the first objective, the authors «hypothesized that eating behaviours evolve throughout pregnancy, with a specific increase in susceptibility to hunger across trimesters. [For the second objective, they] hypothesized that changes in eating behaviour differ according to total GWG and pre-pregnancy BMI categories.» (p. 55)

2. Méthode

Échantillon/Matériau :

Type de traitement des données :

3. Résumé

For the first objective, the «results show that pregnant women expressed lower dietary restraint in the third trimester compared with the first. [Concerning the second objective, the authors] did not observe any variations in eating behaviours whether women met, failed to meet, or exceeded GWG total recommendations or according to pre-pregnancy BMI categories. Overall, dietary restraint scores varied throughout pregnancy, with a decrease observed between the first and the third trimesters. Maintaining high levels of restraint during pregnancy may be challenging considering the supposedly increased hunger associated with pregnancy’s high metabolic demand. [They] also observed a trend for an increase in internal locus of hunger across trimesters.» (p. 57-58) The author concludes by suggesting that eating «behaviours before pregnancy may have a larger impact on eating behaviours during pregnancy in comparison with GWG itself, but this remains to be confirmed […].» (p. 59)
