研究问题
Finally, we compared remaining life expectancy at age 85 (e 85 ) and decomposed the corresponding birthplace-group differences by cause of death to examine the oldest-old.；These comparisons therefore support only a hypothesis about historical exposure and do not demonstrate that tobacco use produced the observed cause-specific contributions.；However, the available data cannot establish whether these indirect effects differed by birthplace or quantify their contribution to the narrowing gap.
方法
Methods Data source We used routinely collected mortality and population data from the Hong Kong Census and Statistics Department (C&SD).；Statistical analysis We began the life table at exact age 15 because the study focused on adult mortality; registered deaths before age 15 accounted for only a small proportion of deaths in both birthplace groups (OSM Fig.；If a primary-analysis bootstrap replicate had zero terminal deaths, we used that stratum’s point-estimate 100+ mortality rate.
核心结论
We identified no study that traced sex-specific differences in adult remaining life expectancy between Hong Kong-born (HK-born) and Mainland China/Macao/Taiwan-born (MMT-born) residents over time, decomposed these differences jointly by age and cause of death, and assessed heterogeneity by length of stay.；Although previous research simply reported life expectancy by migrant status, we identified no study that systematically traced sex-specific differences between HK-born and MMT-born residents across multiple years, decomposed these differences jointly by age and cause of death, and assessed heterogeneity by length of stay (LOS) within the MMT-born population.；We report 95% confidence intervals based on the 2.5th and 97.5th percentiles of the bootstrap distribution.
局限
However, the gap was concentrated at older ages and in pneumonia and cancers.；However, these marriages did not imply uniform social integration: they were characterized by educational hypergamy, with Hong Kong-born husbands tending to be more educated than their Mainland-born wives, indicating that cross-boundary incorporation proceeded alongside persistent social stratification rather than simple random migration.
