低血清维生素D与高纬度、年龄、体脂百分比和脂肪鱼摄入量低有关。关于阿拉斯加原住民维生素D浓度的文献很少。本研究旨在调查阿拉斯加西南部Yup'ik人的血清25-羟基维生素D（25（OH）D）浓度与人口统计学和生活方式变量的关系，特别是使用当地收获的（当地）食物。横断面研究。我们估计25（OH）D，膳食维生素D和钙，从当地食物和人口统计变量的497 Yup'ik人（43%男性）年龄在14-92居住在阿拉斯加西南部的能量百分比。采样大致平均分为合成和非合成的季节，虽然样品的优势，在几个月的日光增加。平均维生素D摄入量为15.1±20.2 µg/d，而当地食物占能量摄入量的22.9±17.1%。维生素D的主要来源是当地鱼类（90.1%），其次是市场食品。平均25（OH）D浓度为95.6±40.7 nmol/L。在25（OH）D浓度的上50百分位数的参与者往往是老年人，男性，较低的体重指数，在合成季节采样，并在上50百分位数的当地食物的使用。远离当地收获的食物可能会增加该人群血清25（OH）D不足的风险。
Low serum vitamin D is associated with higher latitude, age, body fat percentage and low intake of fatty fish. Little documentation of vitamin D concentrations is available for Alaska Native populations. This study was undertaken to investigate serum 25-hydroxyvitamin D (25(OH)D) concentrations of the Yup'ik people of southwestern Alaska in relation to demographic and lifestyle variables, particularly with the use of locally harvested (local) foods. Cross-sectional study. We estimated 25(OH)D, dietary vitamin D and calcium, percent of energy from local foods and demographic variables in 497 Yup'ik people (43% males) aged 14–92 residing in southwestern Alaska. Sampling was approximately equally divided between synthesizing and non-synthesizing seasons, although the preponderance of samples were drawn during months of increasing daylight. Mean vitamin D intake was 15.1±20.2 µg/d, while local foods accounted for 22.9±17.1% of energy intake. The leading sources of vitamin D were local fish (90.1%) followed by market foods. Mean 25(OH)D concentration was 95.6±40.7 nmol/L. Participants in the upper 50th percentile of 25(OH)D concentration tended to be older, male, of lower body mass index, sampled during the synthesizing season, and among the upper 50th percentile of local food use. A shift away from locally harvested foods will likely increase the risk for serum 25(OH)D insufficiency in this population.
