Research objective.
- To study the associations between combinations of single nucleotide polymorphisms and behavioural risk factors with non-communicable diseases and adverse outcomes in women with premature ovarian failure.
Research objectives:
Methods of research:
Subject of study.
Women under 45 with Premature Ovarian Failure (PED). It is planned to include 615 people in the study. The study will have both prospective and retrospective parts. Patients will be divided into 4 groups:
The groups will be comparable in number. All data obtained will be calculated for each group separately. A comparative analysis will then be made for all four groups.
Traditional risk factors, existing non-communicable diseases and the quality of life of patients will be identified using standard research methods.
The selected polymorphism groups are associated with various pathological processes leading to unfavourable cardiovascular outcomes. Their role has not been assessed in patients with premature ovarian failure.
The power of the study was calculated based on the expected number of adverse outcomes.
The division of patients into groups is related to the need to compare and evaluate unfavourable outcomes and non-communicable diseases in patients in order to create a risk scale.

Women diagnosed with premature ovarian failure were selected from different medical institutions in Ryazan and the Ryazan region, all information was communicated to them in a clear and understandable way and they also signed an informed voluntary consent. Premature ovarian failure - defined as the occurrence of secondary amenorrhoea ≥4 months at the age of under 45 years together with FSH levels above 40 IU/L.
Inclusion criteria were: female gender, age at menopause < 45 years, onset of secondary amenorrhoea ≥ 4 months, FSH levels higher than 40 IU/l, or a previous diagnosis of premature ovarian failure.
The control group was formed based on comparability criteria of gender, age and BMI to minimise the influence of phenotype on the results. The control group consisted of women without signs of PEN, so we aimed to compare the health status of these two different groups of women.
