The state of the parameters of the neuro-vegetative system of the inhabitants of the North of the Russian Federation determines the quality and life expectancy of a human in the North. The aim of the research is to study the parameters of the neuro-vegetative status of visiting women of Ugra in part of age-related changes. Within the framework of the Helsinki Declaration, using the device «Elox-01», three age groups of 15 people each were examined. Registration of organism parameters was carried out in 5 minutes. We obtained samples of the parameters of the sympathetic - x1 and parasympathetic - x2 systems. Matrices of pairwise comparisons for x1 and x2 were constructed and phase portraits of each subject were calculated in coordinates x1 and x2. For the parameters of the neuro-vegetative system, the effect of Eskov-Zinchenko is proved, which is manifested by the loss of uniformity of the recorded samples x1 and x2. The calculation of the parameters of quasi-attractors in the phase coordinates x1 and x2 shows the differences in the age dynamics of the parameters of the neuro-vegetative system of three age groups. The calculation of matrices of pairwise comparisons of samples x1 and x2 proved the statistical instability of the parameters of the neuro-vegetative system. Therefore, we propose to calculate the parameters of quasi-attractors in the coordinates x1 and x2. Such quasi-attractors really in an integrative form show the differences between different age groups.
