Study Suggests Hereditary Rosacea Link
A survey conducted by the National Rosacea Society (NRS) and published in Rosacea Review found that nearly 52% of the 600 surveyed had a relative who also suffered from the condition and that people of some nationalities are more likely than others to develop the disorder.
Familial Rosacea Association
Of those who said they had a relative with rosacea, most indicated it was an immediate family member. Thirty percent reported their mother has or had rosacea, while 35% indicated their father, 28% cited a sister and 24% named a brother. In some cases more than one family member was indicated.
National Ancestry Association
In addition to family history, the survey found that national ancestry also may be an indication of relative risk for rosacea. Thirty-one percent of the respondents reported they had at least one parent of Irish ancestry, although only 11% of the United States population is of Irish heritage, according to the 2000 U.S. Census figures.
It was determined that those of German and English heritage seem to be highly prone to rosacea as well. Forty-one percent of patients responding to the survey reported they had some German ancestry, compared to 15% of the U.S. population, and more than 30% reported English ancestry, versus 9% reporting English ancestry in the national census.
Other nationalities in which rosacea was present at a higher rate than the ethnicity is represented in the U.S. population include Scandinavian, Scottish, French, Polish, Russian, Lithuanian, Hungarian and Czech.
