Abstract:
According to the WHO, 1.7 billion people on the planet are overweight, and by 2025, the number of obese people in the world will reach 300 million people [1]. According to the definition of the World Health Organization, obesity is defined as an unusual or excessive accumulation of fat that can be harmful to health. It is a global medical and social problem for the health of all countries and patients of all ages. The incidence of metabolic syndrome (MS) in the world is almost 40% of the adult population, and obesity is 13% (Lee et al., 2020). The global prevalence of obesity has almost tripled from 1975 to 2016 and continues to increase. In the United States - 42.4% in 2018, in France, the prevalence of obesity among adults was 17% in the same year.
Recent studies have shown that both vitamin D deficiency and carriage of certain polymorphisms of the vitamin D receptor gene may be associated with an increase in the fractions of atherogenic blood lipids [2].
