To study the prevalence of vitamin D deficiency and to identify possible predictors of vitamin D deficiency in five main immigrant groups in Oslo.
Cross-sectional, population-based.
City of Oslo.
In total, 491 men and 509 women with native countries Turkey, Sri Lanka, Iran, Pakistan and Vietnam living in the county of Oslo.
Median serum 25(OH)D level (s-25(OH)D) was 28 nmol/l, ranging from 21 nmol/l in women born in Pakistan to 40 nmol/l in men born in Vietnam. Overall prevalence of vitamin D deficiency defined as s-25(OH)D<25 nmol/l was 37.2%, ranging from 8.5% in men born in Vietnam to 64.9% in women born in Pakistan. s-25(OH)D did not vary significantly with age. s-25(OH)D was higher in blood samples drawn in June compared to samples obtained in April, but not significantly for women. Reported use of fatty fish and cod liver oil supplements showed a strong positive association with s-25(OH)D in all groups. Education length was positively associated with s-25(OH)D in women, whereas body mass index (BMI) was inversely associated with s-25(OH)D in women. These two variables were not related to vitamin D deficiency in men.
There is widespread vitamin D deficiency in both men and women born in Turkey, Sri Lanka, Iran, Pakistan and Vietnam residing in Oslo. The prevalence of vitamin D deficiency is higher in women than in men, and it is higher in those born in Pakistan and lower in those born in Vietnam compared to the other ethnic groups. Fatty fish intake and cod liver oil supplements are important determinant factors of vitamin D status in the groups studied. BMI and education length are also important predictors in women.
研究奥斯陆五个主要移民群体中维生素D缺乏症的患病率，并确定维生素D缺乏症的可能预测因素。
基于人群的横断面研究。
奥斯陆市。
共有491名男性和509名女性，他们的原籍国分别为土耳其、斯里兰卡、伊朗、巴基斯坦和越南，居住在奥斯陆郡。
血清25(OH)D水平（s-25(OH)D）中位数为28nmol/l，范围从出生于巴基斯坦的女性的21nmol/l到出生于越南的男性的40nmol/l。定义为s-25(OH)D<25nmol/l的维生素D缺乏症总体患病率为37.2%，范围从出生于越南的男性的8.5%到出生于巴基斯坦的女性的64.9%。s-25(OH)D随年龄变化不显著。与4月份采集的样本相比，6月份采集的血样中s-25(OH)D较高，但女性样本差异不显著。报告食用富含脂肪的鱼类和鳕鱼肝油补充剂与所有群体的s-25(OH)D呈强正相关。女性的受教育年限与s-25(OH)D呈正相关，而女性的体重指数（BMI）与s-25(OH)D呈负相关。这两个变量与男性的维生素D缺乏症无关。
居住在奥斯陆的出生于土耳其、斯里兰卡、伊朗、巴基斯坦和越南的男性和女性中普遍存在维生素D缺乏症。女性维生素D缺乏症的患病率高于男性，与其他种族群体相比，出生于巴基斯坦的人患病率更高，出生于越南的人患病率更低。在研究的群体中，摄入富含脂肪的鱼类和鳕鱼肝油补充剂是维生素D状态的重要决定因素。BMI和受教育年限也是女性维生素D缺乏症的重要预测因素。
