Metabolic syndrome (MS) is a very serious pathological condition that occurs in the clinical practice of doctors of various specialties. Often, the presence of MS aggravates the course of comorbidities, while various diseases can serve as a risk factor for its development. The significant prevalence of MS determines the need for its early diagnosis for timely correction and prevention of its long-term complications.The aim. To systematize data on the prevalence of metabolic syndrome in various countries and populations and to discuss the most frequently used diagnostic criteria, including racially and ethnically differentiated ones.Materials and method. A literary search was carried out using scientific databases: eLIBRARY, PubMed.NCBI, CyberLeninka, the official website of IDF for the period from 1999 to 2020.Results. It was found that despite different diagnostic criteria used for MS, its prevalence in many countries is comparable (10–30 %) but differs in different populations. Thus, MS occurs more often in Caucasians than among Asians, and its prevalence is significantly higher in the newcomer vs the indigenous population. Nevertheless, a comparative analysis of the frequency of MS is difficult due to the use of research results based on different approaches to its diagnosis in the literature presented in the literature. Although the analysis of literature data indicates the existence of specific features of the prevalence of MS in different populations, the differentiated approaches to detecting MS depending on the race of patients, which are necessary for many countries, have not yet been sufficiently developed.

Background. PCOS is one of the most common endocrinological pathologies in women of reproductive age, manifested by a wide range of clinical manifestations. There are many unresolved issues related to the pathogenesis, diagnosis and treatment of this pathological condition in different periods of reproductive age. Aim the objective of the study was to identify the features of the functioning of the pituitary-ovarian system in women with PCOS at different periods of reproductive age. Methods. Study was performed in 20172019 at the FSPSI SCFHHRP, and involved women aged 1845 years. The study groups included women (a group of women with PCOS and a control group) in the follicular phase from 1 to 12 days of the menstrual cycle. As a result of the survey, a group of 44 women with PCOS and a group of 56 healthy women were formed. PCOS was diagnosed according to ESHRE/ASRM criteria (Rotterdam, 2003). Next, subgroups of women in early reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 29) and a control group (n = 22). And groups of women in late reproductive age from 35 to 45 years were formed: a group of women with PCOS (n = 15) and a control group (n = 34). Conducted: questionnaire survey, general and gynecological examination, ultrasound examination of the pelvic organs, laboratory tests, statistical data analysis. Results. In women with polycystic ovary syndrome of early reproductive age (1835 years), we detected an increase in the level of testosterone by 2 times, DHEA-S by 1.3 times, 17-OH-progesterone by 2 times, sex steroid-binding globulin by 1.4 times, in comparison with control group. The ratio of luteinizing hormone to follicle-stimulating hormone increased by 52%. In women with polycystic ovary syndrome of late reproductive age (3545 years), we detected an increase in the level of testosterone by 1.5 times, 17-OH-progesterone by 1.9 times, luteinizing hormone by 1.4 times, sex steroid-binding globulin by 1.6 times, in comparison with control group, without any significant differences in DHEA-S. At the same time, the ratio of luteinizing hormone to follicle-stimulating hormone increased by 60%. Conclusion. The hormonal profile of women with PCOS of early and late reproductive period is characterized by series of age-related changes in the pituitary-ovarian system, which should be taken into account in preventive and therapeutic measures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
