The SAMINOR 2 Clinical Survey

The second survey of the Population-based Study on Health and Living Conditions in Regions with Sami and Norwegian Populations (SAMINOR 2) was conducted by the Centre for Sami Health Research at UiT The Arctic University of Norway in 2012–2014. The survey was conducted in two stages. Stage 2, the SAMINOR 2 Clinical Survey, also called the “Health and Lifestyle Survey”, was conducted by the Centre for Sami Health Research in 2012–2014 in ten selected municipalities, all of which participated in SAMINOR 1 and in stage 1 of SAMINOR 2.

Municipalities Selected for Participation in the SAMINOR 2 Clinical Survey

  • Skånland and Evenes (September-October 2012)
  • Karasjok (January-February 2013)
  • Kautokeino (February-March 2013)
  • Porsanger (April-May 2013)
  • Kåfjord (September-October 2013)

Implementation of the Survey 

Prior to the survey, cooperation was established with the authorities in each municipality. These provided suitable premises for examination sites or other assistance, and freed municipal health workers to work in the clinical survey. The Centre for Sami Health Research rented or borrowed premises in the various municipalities and established an examination site for the period of data collection. Mostly, local health workers were freed to work at the examination site. A total of 70 hired staff were involved in collecting the data.

About one month before the survey, the selected population received a pamphlet in the post containing information about the forthcoming health survey (pamphlet in Samipamphlet in Kven). The target group was the entire population aged 40-79, regardless of whether or not they participated in Stage 1. They subsequently all received a personal invitation, including an information letter, a scheduled appointment (also in Sami) and a questionnaire. About halfway through the survey period, those who had not yet attended received a reminder in the post (also in Sami).

The survey consisted of a clinical examination and blood tests, and participants were also asked to complete a questionnaire and bring it to the appointment. Participants aged 70–79 received a separate questionnaire designed for older people. There were thus two questionnaires related to Stage 2: one of eight pages for people aged 40 to 69 years (also in Sami) and one of four pages for people aged 70 to 79 years (also in Sami).

 

Clinical measurements

Height, weight, hip and waist circumference, pulse and blood pressure were measured.

 

Blood samples

Non-fasting blood samples were taken. Long-term blood sugar (HbA1c) and haemoglobin levels were analysed on site. All participants were offered written results of the measures taken at the station, including long-term blood sugar and haemoglobin levels. In the case of abnormal findings, participants were referred to their GP. Other samples were frozen and sent to UiT The Arctic University of Norway to be stored in the biobank. Lipids, biomarkers for diabetes, inflammatory reactions, iron status and some vitamins were analysed at the University Hospital of North Norway in autumn 2014. In spring 2016, vitamin D was analysed in Helsinki, Finland. Environmental toxins have also been analysed for a selection of participants. The remaining blood samples were stored in the biobank for later analysis.
