The aim of the study was to estimate and compare the 8-year cumulative incidence of diabetes mellitus (DM) among Sami and non-Sami inhabitants of rural districts in Northern Norway.
Longitudinal study based on linkage of two cross-sectional surveys, the SAMINOR 1 Survey (2003-2004) and the SAMINOR 2 Clinical Survey (2012-2014). Ten municipalities in rural Northern Norway were included in the study. DM-free participants aged 30 and 36-71 years in SAMINOR 1 were followed from 2 years after SAMINOR 1 to attendance in SAMINOR 2. The average follow-up time was 8.1 years. Of 5875 subjects who had participated in SAMINOR 1 and could potentially be followed to SAMINOR 2, 3303 were included in the final analysis. Self-reported DM and/or HbA1c ≥ 6.5% were used to identify incident cases of DM.
At baseline, body mass index (BMI) and waist-to-height ratio (WHtR) were higher among Sami than among their non-Sami counterparts. After 8 years of follow-up, 201 incident cases of DM were identified (6.1% both Sami and non-Sami subjects). No statistically significant difference was observed in the cumulative incidence of DM between the Sami and non-Sami.
No statistically significant difference in the 8-year cumulative incidence of DM among Sami and non-Sami was observed, although Sami men and women had higher baseline BMI and WHtR.
本研究旨在评估和比较挪威北部农村地区萨米族和非萨米族居民8年糖尿病（DM）累积发病率。
基于两项横断面调查（萨米族健康研究1调查（2003 - 2004年）和萨米族健康研究2临床调查（2012 - 2014年））的纵向研究。挪威北部农村的10个自治市纳入研究。萨米族健康研究1中年龄在30岁以及36 - 71岁且无糖尿病的参与者从萨米族健康研究1后2年开始随访至参与萨米族健康研究2。平均随访时间为8.1年。在参与萨米族健康研究1且有可能被随访至萨米族健康研究2的5875名受试者中，3303名被纳入最终分析。自我报告的糖尿病和/或糖化血红蛋白（HbA1c）≥6.5%用于确定糖尿病发病病例。
基线时，萨米族的体重指数（BMI）和腰高比（WHtR）高于非萨米族。随访8年后，确定了201例糖尿病发病病例（萨米族和非萨米族受试者均为6.1%）。萨米族和非萨米族之间糖尿病累积发病率未观察到统计学显著差异。
尽管萨米族男性和女性基线BMI和WHtR较高，但在萨米族和非萨米族之间未观察到8年糖尿病累积发病率的统计学显著差异。
