The impact of migration in all-cause mortality: the Turin Longitudinal Study, 1971-2005.

North-western Italy has a long history of domestic influx, however little is known on how migrant mortality compares to mortality at the local level. While geographic mortality gradients may play a role, conceptualizations developed for international migration may also be relevant. Using this theoretical framework, the study investigated immigrant-native differentials in the north-western city of Turin through a 34-year follow-up that was facilitated by the Turin Longitudinal Study.

[Inequalities in health expectancies in England and Wales--small area analysis from the 2001 Ccensus.

This study investigates inequalities in the expectation of life without disability and life in good health using 2001 Census data at small area (ward) level for England and Wales. Inequalities were examined both nationally and within regions by computing life expectancies and health expectancies in groups of wards (twentieths) aggregated according to the Carstairs deprivation score. The results showed that the inequality gaps were significantly larger for health expectancies compared with life expectancy; they were wider for disability-free life expectancy than healthy life expectancy; and, for all measures, were wider for males.

Differentials in the femininity ratio among centenarians: variations between northern and southern Italy from 1870.

Significant differentials have been observed between Italian regions in the distribution of centenarians by sex, from two women per man in the south to over eight in certain regions in the north. In order to explain these differentials we studied the evolution of the femininity ratio (FR), using a longitudinal approach to follow the ageing process in two cohorts, and making use of nearly all the statistical data available since the time of the Unification of Italy in 1870. Significant differentials in the FR observed at the age of 100 are mainly due to mortality differentials among men over the age of 60.

The influence of social relations on mortality in later life: a study on elderly Danish twins.

Purpose: We examined whether the presence of a spouse and the frequency of interaction with children, relatives, and friends significantly influence the risk of dying in late life. We assessed these effects separately by gender, controlling for self-reported health. In addition, we examined whether interaction with the co-twin has a different impact on mortality for identical and fraternal twins.
