Aboriginal populations living above the Arctic Circle are at particularly high risk of vitamin D deficiency due to limited ultraviolet B exposure (related to geographic latitude) and inadequate dietary intake (recently related to decreased traditional food consumption). Major changes in diet and lifestyle over the past 50 years in these populations have coincided with increased prevalence rates of rickets, cancer, diabetes, and obesity, each of which may be associated with vitamin D inadequacy. This review examines the risk factors for vitamin D inadequacy, the associations between vitamin D and disease risk at high geographic latitudes, and the recommendations for improving vitamin D status particularly among aboriginal Arctic populations. Traditional foods, such as fatty fish and marine mammals, are rich sources of vitamin D and should continue to be promoted to improve dietary vitamin D intake. Supplementation protocols may also be necessary to ensure adequate vitamin D status in the Arctic.
因有限的紫外线 B 暴露（与地理纬度有关）和不足的饮食摄入（最近与传统食物消费减少有关），生活在北极圈以上的原住民人群特别容易患维生素 D 缺乏症。在过去的 50 年中，这些人群的饮食和生活方式发生了重大变化，佝偻病、癌症、糖尿病和肥胖的发病率也有所上升，而这些疾病都可能与维生素 D 不足有关。本文综述了维生素 D 不足的危险因素、高地理纬度下维生素 D 与疾病风险之间的关系，以及改善维生素 D 状况的建议，特别是在原住民的北极地区。传统食物，如高脂肪鱼类和海洋哺乳动物，是维生素 D 的丰富来源，应继续加以推广，以改善饮食中的维生素 D 摄入。补充方案也可能是确保北极地区维生素 D 充足的必要手段。
