The first Hungarian Twin Registry was established in Budapest in 1970 through the
mandatory reporting of multiple-births. In the 1980s a second, volunteer adult registry
was also founded. Unfortunately, both registries ceased to exist in the 1990s. Efforts
started in 2006 to revive a Hungarian twin registry. The team spearheading this effort
reports here on this progress. Currently, the voluntary Hungarian Twin Registry consists
of 310 adult twin pairs and multiplets. Current research focuses on cardiovascular
and respiratory health and yielded multiple awards and publications. Efforts are on
the way to expand into social, psychological, and obesity studies.
