To investigate the occurrence of clinical, psychosocial and behavioural risk factors for cardiovascular diseases (CVD) among reindeer herding (RS) and non-reindeer herding Sami (NRS).
A retrospective cohort study, comparing risk factors behind CVD between Sami and non-Sami, RS and NRS, and Sami men and women.
A cohort of 611 Swedish Sami (276 men and 335 women) was constructed from national population registers. A twice as large control cohort of non-Sami was created, matched by age, gender and area of residence. Information on risk factors was obtained from a database containing clinical and psychosocial-behavioural data from a regional CVD preventive programme for the period 1990-2001.
The Sami and the non-Sami showed similar risk factor patterns. The main differences were related to working conditions and lifestyle factors of the RS. The RS men had lower blood pressure, were more physically active and had higher job demand and decision latitude. The RS women showed more negative scores on the indices of the job strain model.
Previously reported differences in CVD mortality between Sami and non-Sami, and Sami men and women, can only partly be explained by different exposure to the psychosocial and behaviour risk factors investigated in this study.
调查驯鹿放牧的萨米人（RS）和非驯鹿放牧的萨米人（NRS）中心血管疾病（CVD）的临床、心理社会和行为风险因素的发生情况。
一项回顾性队列研究，比较萨米人与非萨米人、驯鹿放牧的萨米人与非驯鹿放牧的萨米人以及萨米男性与女性之间心血管疾病背后的风险因素。
从国家人口登记册中选取了611名瑞典萨米人（276名男性和335名女性）组成队列。创建了一个规模为其两倍的非萨米人对照队列，按照年龄、性别和居住地区进行匹配。风险因素信息来自一个数据库，该数据库包含1990 - 2001年期间一个地区心血管疾病预防项目的临床和心理社会行为数据。
萨米人和非萨米人表现出相似的风险因素模式。主要差异与驯鹿放牧的萨米人的工作条件和生活方式因素有关。驯鹿放牧的萨米男性血压较低，身体活动更多，工作要求和决策自由度更高。驯鹿放牧的萨米女性在工作压力模型指标上得分更负面。
先前报道的萨米人与非萨米人以及萨米男性与女性在心血管疾病死亡率上的差异，只能部分地由本研究中所调查的心理社会和行为风险因素的不同暴露情况来解释。
