Summary 

A national survey was conducted in 2010-2011 estimating the mean dietary salt intake of 1448 people. Participants in age groups of 15-29, 30-44, 45-59, and 60+ for men and women were recruited. The Federal Statistical Office provided a list of randomly selected households in each canton. One person per household was selected using a computer generated random number, and asked to participate. Due to low participation, the sample was completed by recruiting volunteers (mainly in the 15-29 age range), which limits its representativeness.

The study consisted of two visits to a study center, before and after a 24-hour urine collection. Resting blood pressure was measured 10 times per participant. Weight, height and abdominal perimeter were measured at the first visit. Body mass index (BMI) was calculated. At the second visit, participants were asked to fill in a questionnaire about lifestyle, medical history and salt-related health issues; an optional blood sample was taken.
