We evaluated temporal and regional inequalities in adverse birth outcomes between Anglophones and Francophones of a Canadian province.
Odds ratios and rate differences in preterm birth (PTB, <37 gestational weeks) and small-for-gestational-age (SGA) birth were computed for Anglophones relative to Francophones for singleton live births in Québec from 1981 to 2008 (N = 2,292,237), adjusting for maternal characteristics. Trends over time and residential region were evaluated.
Rates of PTB and SGA birth overall were lower for Anglophones relative to Francophones, but temporal and regional trends varied by outcome. Although PTB rates increased over time, inequalities between Francophones and Anglophones were relatively stable. In contrast, inequalities in SGA birth narrowed over time as Francophone rates declined more than Anglophones. Inequalities in SGA birth favored Anglophones overall, but the gap gradually reversed in Montréal (the largest metropolitan center) to currently favor Francophones.
PTB and SGA birth rates favored Anglophones over Francophones. The linguistic gap was generally stable over time for PTB, but narrowed or reversed for SGA birth. Language may be used to capture inequalities in perinatal health in countries where different linguistic groups predominate.
我们评估了加拿大一个省份的英语和法语使用者之间不良出生结局的时间和区域不平等。
我们计算了 1981 年至 2008 年魁北克的单胎活产中，英语使用者相对于法语使用者早产（<37 孕周）和小于胎龄儿（SGA）出生的比值比和率差，并根据产妇特征进行了调整（N=2,292,237）。评估了时间和居住地区的趋势。
总的来说，英语使用者的早产和 SGA 出生比率相对于法语使用者较低，但时间和区域趋势因结果而异。尽管早产率随时间增加，但法语使用者和英语使用者之间的不平等相对稳定。相比之下，SGA 出生的不平等随着法语使用者的比率下降超过英语使用者而逐渐缩小。SGA 出生的不平等总体上有利于英语使用者，但在蒙特利尔（最大的都会中心），差距逐渐逆转，目前有利于法语使用者。
早产和 SGA 出生率有利于英语使用者而非法语使用者。对于早产，语言差距在时间上通常是稳定的，但对于 SGA 出生，差距缩小或逆转。在不同语言群体占主导地位的国家，语言可能被用来捕捉围产期健康的不平等。
