Migrant populations consist of migrants with differences in generational status and length of residence. Several studies suggest that health outcomes differ by generational status and duration of residence. We examined the association of generational status and age at immigration of the mother with infant mortality in migrant populations in The Netherlands.
Data from Statistics Netherlands were obtained from 1995 through 2000 for infants of mothers with Dutch, Turkish and Surinamese ethnicity. Mothers were categorized by generational status (Dutch-born and foreign-born) and by age at immigration (0-16 and >16 years). The associations of generational status and age at immigration of the mother with total and cause-specific infant mortality were examined.
The infant mortality rate in Turkish mothers rose with lower age at immigration (from 5.5 to 6.4 per 1000) and was highest for Dutch-born Turkish mothers (6.8 per 1000). Infant death from perinatal and congenital causes increased with lower age at immigration and was highest in the Dutch-born Turkish women. In contrast, in Surinamese mothers infant mortality declined with lower age at immigration (from 8.0 to 6.3 per 1000) and was lowest for Dutch-born Surinamese mothers (5.5 per 1000). Generational status and lower age at immigration of Surinamese women were associated with declining mortality of congenital causes.
Total and cause-specific infant mortality seem to differ according to generational status and age at immigration of the mother. The direction of these trends however differs between ethnic populations. This may be related to acculturation and selective migration.
移民群体由代际地位和居住时长不同的移民组成。多项研究表明，健康结果因代际地位和居住时长而异。我们研究了荷兰移民群体中母亲的代际地位和移民年龄与婴儿死亡率之间的关联。
获取了荷兰统计局1995年至2000年期间荷兰、土耳其和苏里南裔母亲所生婴儿的数据。母亲们按代际地位（荷兰出生和外国出生）以及移民年龄（0至16岁和大于16岁）进行分类。研究了母亲的代际地位和移民年龄与总婴儿死亡率及特定病因婴儿死亡率之间的关联。
土耳其母亲的婴儿死亡率随移民年龄降低而上升（从每1000例5.5例升至6.4例），荷兰出生的土耳其母亲的婴儿死亡率最高（每1000例6.8例）。围产期和先天性病因导致的婴儿死亡随移民年龄降低而增加，在荷兰出生的土耳其女性中最高。相比之下，在苏里南母亲中，婴儿死亡率随移民年龄降低而下降（从每1000例8.0例降至6.3例），荷兰出生的苏里南母亲的婴儿死亡率最低（每1000例5.5例）。苏里南女性的代际地位和较低的移民年龄与先天性病因死亡率下降有关。
总婴儿死亡率和特定病因婴儿死亡率似乎因母亲的代际地位和移民年龄而异。然而，这些趋势的方向在不同种族群体之间有所不同。这可能与文化适应和选择性移民有关。
