The Skin Conditions questionnaire is an additional assessment among adult Lifelines participants. The digital questionnaire was developed at the initiative of the UMCG Department of Dermatology (NL).
The aim of the questionnaire was to gain more insight into hidradentitis supperativa and eczema in the general population.

The collected SKIQ data is currently still under embargo. Please contact the Lifelines data managers at data@lifelines.nl for more information.

The digital questionnaire was sent out between February and May 2020.
~136,000 adult Lifelines participants received the questionnaire, of which ~58,000 participants (43%) responded.
