Italian immigrants live longer

07.01.2013
Immigrants from Italy live longer than members of their host country. However, the risk of mortality is considerably higher for their offspring than their Swiss counterparts.
More exposed to the influences of the host country, the second generation detaches itself from the healthy southern lifestyle and the close-knit family network and has poorer educational opportunities than locals. Men are affected more strongly by this than women, as a study conducted by the University of Zurich’s Institute of Social and Preventative Medicine reveals.

Although immigrants from Italy and their offspring form one of the largest demographic groups in Switzerland, there are hardly any studies on their state of health and risk of mortality. In a first for Switzerland, Silvan Tarnutzer and Matthias Bopp from the University of Zurich’s Institute of Social and Preventative Medicine calculated unbiased mortality risks for people with an Italian migrant background.

Immigrants from Italy live longer than Swiss people

Compared to Swiss people born in Switzerland, immigrant Italians exhibit a mortality risk that is roughly ten percent lower. Younger male Italians especially fair better than the Swiss, although the differences become increasingly smaller the older they are. At first glance, this finding is astonishing as Italian immigrants often only have a low school education and below-average income – both factors associated with higher risks of mortality. The greater prevalence of smoking and overweight people and poorer assessment of one’s own health in Italy compared to Switzerland also point in the same direction. On a behavioral level, this is merely counteracted by the Mediterranean diet – the frequent consumption of fish, fruit, vegetables and olive oil – and the distinctive social network. First author of the study Silvan Tarnutzer thus assumes that the lower risks of mortality can primarily be put down to the so-called “healthy migrant effect”, according to which particularly healthy and bold people often migrate while weaker and ill people do not even start looking for a job abroad in the first place or, in the event of illness, return to their country of origin.

Next generations at greater risk of mortality

As far as the offspring of migrants born in Switzerland are concerned, however, this head start disappears. The lifestyle of the host country influences Italians from subsequent generations during their personal development and they detach themselves from the healthy southern lifestyle and close-knit family network. For instance, Italians born in Switzerland display a 16 percent greater risk of mortality than locals. “Presumably as a result of the double burden of poorer educational opportunities and a more unfavorable lifestyle,” says co-author Matthias Bopp. Interestingly, women seem to be affected by this unfavorable risk constellation to a lesser degree. “Due to their large number and on average younger age, the male offspring of Italian immigrants constitutes a special target group for prevention and the promotion of health,” concludes Tarnutzer.

Background
Many immigrants from Italy have a residence in Switzerland and Italy, which means that deaths abroad are often not registered in Switzerland. This leads to an underestimation of the actual mortality risks.

By using the “Swiss National Cohort”, a combination of data from the 1990 census and the death and foreigner register from 1990 and 2008, however, Tarnutzer and Bopp were able to avoid this under-registration. In doing so, they distinguished between the immigrant generation and subsequent generations born in Switzerland.

Im Focus: Attosecond camera for nanostructures

Physicists of the Laboratory for Attosecond Physics at the Max Planck Institute of Quantum Optics and the Ludwig-Maximilians-Universität Munich in collaboration with scientists from the Friedrich-Alexander-Universität Erlangen-Nürnberg have observed a light-matter phenomenon in nano-optics, which lasts only attoseconds.

The interaction between light and matter is of key importance in nature, the most prominent example being photosynthesis. Light-matter interactions have also...

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
