Intentions : The «objective [of this research] was to determine if differences in interpregnancy intervals were present between Anglophones and Francophones in the province of Quebec, Canada.» (p. 200)
Questions/Hypothèses : The authors’ «hypothesis was that socioeconomically disadvantaged Anglophones are presently at greater risk of suboptimal interpregnancy intervals compared with Francophones.» (p. 201)
Échantillon/Matériau : The sample was composed of 622 812 «live birth and stillbirth files from the Ministry of Health and Social Services for all infants to women who gave birth in Quebec, Canada, 1989−2011. The data covered the entire province, and contained maternal characteristics such as language and parity as well as information on the prior delivery.» (p. 201)
Type de traitement des données : Analyse statistique
«In this study, [the authors] found differences in short and long interpregnancy intervals between Anglophones and Francophones of Quebec. Socioeconomically disadvantaged Anglophones had intervals that were less favourable than Francophones for both short and long intervals. At short intervals, Anglophones with no high school diploma, who lived in rural areas, or were materially deprived had interpregnancy intervals that were systematically shorter than Francophones. At long intervals, Anglophones with no high school diploma, who lived in rural areas, or were materially deprived had interpregnancy intervals that were systematically longer than Francophones. The differences persisted over time, and were stronger for younger women. In contrast there was no difference between socioeconomically advantaged Anglophones and Francophones. These findings add to the growing evidence that socioeconomically disadvantaged Anglophones may be a vulnerable population in Quebec, and are concerning as Anglophones have higher fertility, and suboptimal interpregnancy intervals are associated with a wide range of adverse maternal and perinatal outcomes.» (p. 204)
