Examination of children aged 3 to 17 years and adult population including parturients living in Naryan-Mar and northern settlements of the Nenets national district revealed the reduced calcium and elevated phosphorus concentrations in the blood serum of the examinees as compared with respective parameters in analogous population groups living in the middle zone of Russia (Moscow and Kazan). These changes, particularly marked in winter and spring, are determined by national and local features of the diet poor in calcium and containing excess amount of phosphorus. The concentration of 25-hydroxyvitamin D in the blood serum of the population living in the Extreme North was 2 times lower than that in the population of the middle zone, constituting 15-20 and 30-40 ng/ml, respectively. The reason for a lower vitamin D supply in the North is insufficient insulation.
对居住在纳里扬-马尔和涅涅茨民族区北部定居点的3至17岁儿童以及包括产妇在内的成年人群进行检查发现，与生活在俄罗斯中部地区（莫斯科和喀山）的类似人群组的相应参数相比，受检者血清中的钙浓度降低，磷浓度升高。这些变化在冬季和春季尤为明显，是由钙含量低且磷含量过高的饮食的民族和地方特点所决定的。生活在极北地区的人群血清中25-羟基维生素D的浓度比中部地区人群低2倍，分别为15 - 20 ng/ml和30 - 40 ng/ml。北方维生素D供应较低的原因是保暖不足。
