Abstract

Objectives: To examine the relationship between “traditional Sami” dietary pattern and 42 mortality in a general northern Swedish population. 43 Study design: Population-based cohort study 44 Methods: We examined 77 319 subjects from the Västerbotten Intervention Program (VIP) 45 cohort. A traditional Sami diet score was constructed by adding one point for intake above the 46 median level of red meat, fatty fish, total fat, berries and boiled coffee, and one point for 47 intake below the median of vegetables, bread and fibre.. Hazard ratios (HR) for mortality 48 were calculated by Cox regression. 49 Results: Increasing traditional Sami diet scores were associated with slightly elevated all-50 cause mortality in men [Multivariate HR per one-point increase in score 1.04 (95% CI 1.01-51 1.07), P =0.018], but not for women [Multivariate HR 1.03 (95% CI 0.99-1.07), P =0.130]. 52 This increased risk was approximately equally attributable to cardiovascular disease and 53 cancer, though somewhat more apparent for cardiovascular disease mortality in men free from 54 diabetes, hypertension and obesity at baseline [Multivariate HR 1.10 (95% CI 1.01-1.20), P 55 =0.023]. 56 Conclusions: A weak increased all-cause mortality was observed in men with higher 57 traditional Sami diet scores. However, due to the complexity in defining a “traditional Sami” 58 diet, and the limitations of our questionnaire for this purpose, the study should be considered 59 exploratory, a first attempt to relate a “traditional Sami” dietary pattern to health endpoints. 60 Further investigation of cohorts with more detailed information on dietary and lifestyle items 61 relevant for traditional Sami culture is warranted.
