Fiche synthèse

1. Objectifs


Intentions :
« [...] evaluate the interaction between education and maternal foreign born status in relation to [low birth weight] LBW, [small for gestational age]SGA birth and [preterm birth] PTB. » (p. 402)

Questions/Hypothèses :
« Is the epidemiological paradox and the healthy migrant effect are related? » (p. 402)

2. Méthode


Échantillon/Matériau :
« 98,330 live births to mothers in Montreal, Canada from 1997 to 2001 were analysed. Mothers were categorised as foreign born versus Canadian born. Outcomes were: small for gestational age (SGA) birth; low birth weight (LBW) and preterm birth (PTB). » (p. 402)

Instruments :
« Multilevel logistic regression was used to examine the interaction between maternal education and foreign born status, adjusting for covariates. » (p. 402)

3. Résumé


« The unresolved ’epidemiological paradox’ concerns the association between low socioeconomic status and unexpectedly favourable birth outcomes in foreign born mothers. The ’healthy migrant’ effect concerns the association between foreign born status per se and birth outcomes. The epidemiological paradox and healthy migrant effect were analysed for newborns in a favourable sociopolitical environment. [Results are] [...] not having a high school diploma was associated with LBW [low birth weight] in Canadian (odds ratio (OR) [...] [Conclusions are] [...] the epidemiological paradox associated with low educational attainment was present for SGA birth and LBW but not PTB. Foreign born status was associated with adverse birth outcomes in university-educated mothers, the opposite of the healthy migrant effect. » (p. 402)
