目的:测量2017年Nunavimmiut(居住在Nunavik的因纽特人)成年人的维生素D状况并评估与血清25-羟基维生素D(25(OH)D)相关的因素。
方法:数据来自Qanuilirpitaa?2017年努纳维克因纽特人健康调查,一项横断面研究于2017年8月至10月进行.参与者进行了问卷调查,包括食物频率问卷,并分析血样的总血清25(OH)D。
方法:努纳维克,魁北克北部,加拿大。
方法:使用分层比例模型选择受访者,包括1,155名被确认为因纽特人并拥有完整数据的人。
结果:女性的几何平均血清维生素D水平为65.2nmol/L(95%CI62.9-67.6nmol/L),男性为65.4nmol/L(95%CI62.3-68.7nmol/L)。血清25(OH)D加权患病率<75nmol/L,<50nmol/L,<30nmol/L为61.2%,30.3%,和7.0%,分别。年龄较大的人,女性,生活在较小和/或更南端的社区,和/或消费更多的乡村(传统)食品,低维生素D状态的风险降低。野生鱼的较高消费量与血清25(OH)D浓度的增加特别相关。
结论:重要的是,区域,当地的政策和计划已经到位,以确保收获,分享,和消费营养和文化上重要的国家食品,如北极炭和其他野生鱼类,特别是考虑到北极地区正在进行的气候变化,这影响了可获得性,access,和鱼作为食物的质量。
OBJECTIVE: To measure vitamin D status and estimate factors associated with serum 25-hydroxyvitamin D (25(OH)D) in Nunavimmiut (Inuit living in Nunavik) adults in 2017.
METHODS: Data were from Qanuilirpitaa? 2017 Nunavik Inuit Health Survey, a cross-sectional study conducted in August-October 2017. Participants underwent a questionnaire, including an FFQ, and blood samples were analysed for total serum 25(OH)D.
METHODS: Nunavik, northern Québec, Canada.
METHODS: A stratified proportional model was used to select respondents, including 1,155 who identified as Inuit and had complete data.
RESULTS: Geometric mean serum vitamin D levels were 65·2 nmol/l (95 % CI 62·9-67·6 nmol/l) among women and 65·4 nmol/l (95 % CI 62·3-68·7 nmol/l) among men. The weighted prevalence of serum 25(OH)D < 75 nmol/l, <50 nmol/l <30 nmol/l was 61·2 %, 30·3 % and 7·0 %, respectively. Individuals who were older, female, lived in smaller and/or more southerly communities and/or consumed more country (traditional) foods were at a reduced risk of low vitamin D status. Higher consumption of wild fish was specifically associated with increased serum 25(OH)D concentration.
CONCLUSIONS: It is important that national, regional and local policies and programs are in place to secure harvest, sharing and consumption of nutritious and culturally important country foods like Arctic char and other wild fish species, particularly considering ongoing climate change in the Arctic which impacts the availability, access and quality of fish as food.
