Using the NSHD, the goal of the current study was to compare the childhood, pre-emigration characteristics of the following: non-emigrants with that of emigrants; those who emigrated before the age of 20 with those who emigrated after age 20; and emigrants who remained abroad with those who returned to live in their native country.
The NSHD is based on a representative sample of 5,362 single, legitimate births in England, Scotland or Wales in March 1946.
In each wave of the NSHD, if an individual was no longer available to be interviewed, information was recorded on whether the respondent had died, emigrated and/or was living abroad, refused to participate or could not be contacted.
City/area refers to the city in ECRHS, EGEA, E3N, and SAPALDIA and the country in NSHD (England, Wales, and Scotland).
Random effects were used for the main relevant cluster for each cohort (city/area for E3N, ECRHS, NSHD, and SAPALDIA, or family for EGEA).
Hay fever was twice as common among participants with incident asthma compared with those without asthma (except for NSHD and EGEA at baseline).

's role in HAI prevention will be flexible and will continue to evolve based on needs and input from partners and stakeholders.
By February 2001, the NSHD had identified 12 children who had been diagnosed with leukemia since 1997 and who had lived in Churchill County before their diagnosis.
The NSHD responded to recommendations of the expert panel by approaching the CDC for assistance in Churchill County.
Initially hypothesized causes of the Churchill County cluster included chemical exposures such as jet fuel or benzene, drinking water contamination by a radioactive isotope or naturally occurring arsenic, population mixing, or a new infectious agent, potentially associated with the nearby naval air station (NSHD 2003).
Further information on the CDC investigation and the cluster is available online through the Nevada State Health Division (NSHD 2003).
