The purpose of this study was to review cardiovascular mortality, morbidity, and risk factors in the multiethnic population of the Northwest Territories, Canada.
We analyzed death certificates and hospital records, and used a community health and examination survey.
The age-standardized mortality rate for ischemic heart disease (but not for other heart diseases or stroke) among the Northwest Territories population was lower than among the Canadian population. Among the indigenous Inuit/Eskimos and Indians, the age-standardized mortality rate for all circulatory diseases was lower than Canadians. Among Indian women, the rate approached the Canadian rate and exceeded that of Inuit and non-Natives. Compared with residents of Manitoba, Northwest Territories Inuit adults had a higher prevalence of smoking in all age-sex groups. Obesity was prevalent among older Inuit women and hypertension among young Inuit men. Except for women aged 25 to 44, the total cholesterol and triglyceride levels among Inuit were lower than or not different from Manitoba residents. Relatively high levels of high-density lipoprotein were found in older Inuits.
The epidemiologic pattern of cardiovascular diseases in Arctic Canada differs from that among non-Native, southern Canadians. Rapid sociocultural changes may alter the situation, and health agencies must anticipate such transitions and intensify culturally appropriate control programs.
本研究旨在回顾加拿大西北地区多民族人群的心血管疾病死亡率、发病率及风险因素。
我们分析了死亡证明和医院记录，并采用了社区健康与检查调查。
西北地区人群中缺血性心脏病（而非其他心脏病或中风）的年龄标准化死亡率低于加拿大人群。在原住民因纽特人/爱斯基摩人和印第安人中，所有循环系统疾病的年龄标准化死亡率低于加拿大人。在印第安女性中，该比率接近加拿大比率且超过因纽特人和非原住民。与马尼托巴省居民相比，西北地区因纽特成年人在所有年龄性别组中的吸烟率更高。肥胖在年长的因纽特女性中普遍存在，高血压在年轻的因纽特男性中普遍存在。除25至44岁女性外，因纽特人的总胆固醇和甘油三酯水平低于或与马尼托巴省居民无异。在年长的因纽特人中发现了相对较高水平的高密度脂蛋白。
加拿大北极地区心血管疾病的流行病学模式与加拿大南部非原住民不同。快速的社会文化变化可能会改变这种情况，卫生机构必须预见到此类转变并加强适合当地文化的控制项目。
