背景很少有研究审查死亡率的移民居住在目的地国的持续时间。我研究了南亚移民在英格兰和威尔士居住时间的死亡率。研究对象为2,272名年龄在25-54岁之间的儿童，随访时间为1971 ~ 2000年。南亚移民的全因死亡率随着在英格兰和威尔士居住时间的增加而增加。1971年，居住时间的逐年增加与25-34岁人群的风险比为1.07（95%置信区间[CI] = 1.02-1.13），35-44岁人群为1.03（1.00-1.07），45-54岁人群为1.02（1.00-1.05）相关。心血管疾病死亡率是这一趋势的主要组成部分。居住时间的逐年增加与心血管疾病死亡风险比相关，最年轻、中间和最年长年龄组分别为1.09（1.03-1.16）、1.04（1.00-1.09）和1.02（1.00-1.05）。在冠心病和癌症死亡率方面，也看到了类似的结果。移民年龄与死亡率呈正相关，与居住时间无关，但置信区间较宽。调整社会经济地位并没有改变这些模式。南亚移民的心血管和癌症死亡率随着在英格兰和威尔士居住时间的增加而增加。
Background. Few studies have examined mortality of migrants by duration of residence in the country of destination.Methods. I examined mortality of South Asian migrants by duration of residence in England and Wales. The cohort (N = 2,272, age 25-54 years in 1971) was followed from 1971 to 2000.Results. All-cause mortality of South Asian migrants increased with increasing duration of residence in England and Wales. A yearly increase in duration of residence was associated with a hazard ratio of 1.07 (95% confidence interval [CI] = 1.02-1.13) among persons ages 25-34 years in 1971, 1.03 (1.00-1.07) among those ages 35-44 years, and 1.02 (1.00-1.05) among those ages 45-54. Cardiovascular disease mortality was the main component of this trend. Yearly increases in duration of residence were associated with cardiovascular disease mortality hazard ratios of 1.09 (1.03-1.16), 1.04 (1.00-1.09) and 1.02 (1.00-1.05) for the youngest, middle and oldest age groups, respectively. Comparable results were seen, for coronary heart disease and for cancer mortality. Age at migration was positively related to mortality independent of duration of residence but the confidence intervals were wide. Adjusting for socioeconomic position did not alter these patterns.Conclusions. Cardiovascular and cancer mortality of South Asian migrants increased with duration of residence in England and Wales.
