To assess coffee consumption in the Sami and Norwegian populations and to investigate the impact of unfiltered boiled coffee consumption on serum cholesterol concentrations.
A cross-sectional study. Information was collected by self-administrated questionnaires and total serum cholesterol was analysed. Participants were divided into three ethnic groups: Sami I (Sami used as home language in the last three generations), Sami II (at least one Sami identity marker) and Norwegian.
In an area with Sami, Kven/Finnish and Norwegian populations, the SAMINOR study, 2003-2004.
A total of 5647 men and 6347 women aged 36-79 years.
More than 90 % of the study populations were coffee drinkers. Only 22 % were unfiltered coffee consumers. Sami I had the highest proportion of participants who consumed nine or more cups of unfiltered coffee per day, although the number of participants was limited. Total coffee consumption was associated with increased total cholesterol for men (P < 0·01) and women (P < 0·0001). For those who drank only unfiltered coffee, a significant association was found only in Norwegian men, adjusted for physical activity in leisure time, BMI and smoking habits (P < 0·001). From the lowest (less than five cups) to the highest (nine or more cups) unfiltered coffee consumption category, the mean total cholesterol levels increased by 0·29 mmol/l in Norwegian men.
Unfiltered coffee consumption was lower in the present study compared to previous reports. In general, total coffee consumption was positively associated with total cholesterol levels. However, for unfiltered coffee consumption, an association was found only in Norwegian men.
评估萨米人和挪威人群的咖啡摄入量，并研究饮用未经过滤的煮咖啡对血清胆固醇浓度的影响。
横断面研究。通过自填问卷收集信息，并分析总血清胆固醇。参与者分为三个族群：萨米人 I 组（母语为萨米语的三代人）、萨米人 II 组（至少有一个萨米人身份标志）和挪威人。
在一个有萨米人、特威人和挪威人居住的地区，即 2003-2004 年的 SAMINOR 研究。
年龄在 36-79 岁的共 5647 名男性和 6347 名女性。
超过 90%的研究人群是咖啡饮用者。只有 22%的人饮用未经过滤的咖啡。尽管参与者人数有限，但萨米人 I 组中每天饮用 9 杯或以上未经过滤咖啡的参与者比例最高。总咖啡摄入量与男性（P<0·01）和女性（P<0·0001）的总胆固醇升高有关。对于仅饮用未经过滤咖啡的人，仅在挪威男性中发现了与调整闲暇时间体力活动、BMI 和吸烟习惯有关的显著关联（P<0·001）。从最低（少于 5 杯）到最高（9 杯或以上）的未经过滤咖啡摄入量类别，挪威男性的平均总胆固醇水平升高了 0·29mmol/L。
与之前的报告相比，本研究中未经过滤的咖啡摄入量较低。总的来说，总咖啡摄入量与总胆固醇水平呈正相关。然而，对于未经过滤的咖啡摄入，仅在挪威男性中发现了关联。
