The main purpose of this work was to identify the prevalence of self-reported stomach symptoms after consuming milk among Sami and non-Sami adults.
A cross-sectional population-based study (the SAMINOR study). Data were collected by self-administrated questionnaires.
SAMINOR is a population-based study of health and living conditions conducted in 24 municipalities in Northern Norway during 2003 and 2004. The present study included 15,546 individuals aged between 36 and 79, whose ethnicity was categorized as Sami (33.4%), Kven (7.3%) and Norwegian majority population (57.2%).
Sami respondents had a higher prevalence of self-reported stomach symptoms after consuming milk than the Norwegian majority population. The reporting was highest among Sami females (27.1%). Consumption of milk and dairy products (yoghurt and cheese) was high among all the ethnic groups. However, significantly more Sami than non-Sami never (or rarely) consume milk or cheese, and individuals who reported stomach symptoms after consuming milk had an significant lower intake of dairy products than those not reporting stomach symptoms after consuming dairy products. Sami reported general abdominal pain more often than the majority population. The adjusted models show a significant effect of Sami ethnicity in both men and women on self-reported stomach symptoms after consuming milk. In females, the odds ratio (OR)=1.77 (p=0.001) and in males OR=1.64 (p=0.001).
Our study shows that the Sami population reported more stomach symptoms after consuming milk, suggesting a higher prevalence of milk intolerance among the Sami population than the Norwegian majority population.
这项研究的主要目的是确定萨米族和非萨米族成年人饮用牛奶后自我报告的胃部症状的患病率。
一项基于人群的横断面研究（萨米人健康与生活状况研究）。数据通过自行填写问卷收集。
萨米人健康与生活状况研究是一项于2003年至2004年在挪威北部24个自治市进行的关于健康和生活条件的人群研究。本研究纳入了15546名年龄在36岁至79岁之间的个体，其种族分类为萨米族（33.4%）、克文人（7.3%）和挪威多数人口（57.2%）。
萨米族受访者饮用牛奶后自我报告的胃部症状患病率高于挪威多数人口。报告率在萨米族女性中最高（27.1%）。所有种族群体中牛奶和乳制品（酸奶和奶酪）的消费量都很高。然而，从不（或很少）饮用牛奶或奶酪的萨米族比非萨米族明显更多，并且饮用牛奶后报告胃部症状的个体比饮用乳制品后未报告胃部症状的个体乳制品摄入量显著更低。萨米族比多数人口更常报告一般性腹痛。校正模型显示，萨米族在男性和女性中对饮用牛奶后自我报告的胃部症状均有显著影响。在女性中，优势比（OR）=1.77（p=0.001），在男性中OR=1.64（p=0.001）。
我们的研究表明，萨米族人群饮用牛奶后报告的胃部症状更多，这表明萨米族人群中牛奶不耐受的患病率高于挪威多数人口。
