The life-course approach suggests early health selection and later cumulative burdens can produce different findings depending on study design and time horizon. The study was framed by life-course epidemiology, which links later-life health to accumulated exposures and determinants over time. Later-life health is described as reflecting migration timing, cumulative exposures, institutional context, socioeconomic conditions, and health behaviours. The article suggests childhood migration may have critical-period effects on later health.
