Abstract

The survey describes the influence of vitamin D on woman’s climacteric period. Climacteric period is a stage of transition in woman’s life between the reproductive period and ceasing of hormonal functions of ovaries. The majority of woman has the climacteric signs at the age of 45-50. The climacteric symptoms appear in every region of the world, though symptoms and treatment varies in different cultures and ethnic groups. In 2009 MEDLINE and EMBASE conducted a research, the hypothesis of which was the age of menopause and climacteric symptoms. The study results showed that the average age of menopause in Europe was 50,1-52,8; in North America- 50,5-52,4; in Latin America- 43,8-53; in Asia- 42,1-49,5. The frequency of vasomotor symptoms significantly varies according to the geographical region, the methods of selecting criteria and identification of symptoms. Prevalence of such symptoms ranges in 74% of women, in Europe- 74%, in North America- 36-50%, in Latin America- 45-69% and in Asia- 22-63%. Deficiency of vitamin D is quite wide-spread problem throughout the world as it is tightly connected with human life-style, alimentary obesity, reducing exposition under sun, increasing age (over 50 and living in geographical latitude). Research-studies conducted during last 20 years increased the knowledge about mechanism of vitamin D. More than 400 works have been published. A small number of studies indicates that vitamin D has no useful effect but the majority of studies distinctly confirms its benefits in prevention of women’s diseases
