PCOS Prevalence in Adolescents Under Different Diagnostic Criteria, 2019-2022

Karolina Jakubowska-Kowal's observational study analyzes the prevalence and clinical-hormonal profile of polycystic ovary syndrome (PCOS) among 289 adolescent patients referred for diagnosis due to hyperandrogenism and/or menstrual disorders between 2019 and 2022. The dataset, last updated in 2026, compares outcomes based on the Ibanez, Peña, and Rotterdam diagnostic criteria, reporting prevalence rates from approximately 46% to 59%.

Use Cases

• Compare PCOS prevalence rates based on the Ibanez, Peña, and Rotterdam diagnostic criteria mentioned in the description.
• Analyze correlations between clinical hyperandrogenism, biochemical hyperandrogenism, and other hormonal parameters like LH and testosterone.
• Investigate the association between specific menstrual abnormalities, such as oligomenorrhea >45 days, and PCOS diagnosis.
• Study the relationship between ovarian volume and PCOS across different diagnostic definitions.

Strengths

• Study includes 289 patient records from a defined 2019-2022 period.
• Results include specific prevalence ranges (46% to 59%) and statistical significance values (e.g., p<0.001) for key hormonal parameters.
• Directly compares multiple established diagnostic criteria (Ibanez, Peña, Rotterdam).

Limitations

• Row count and column-level documentation are unknown, requiring manual inspection after download.
• The dataset is very small at 15.9 KB, indicating limited scope.
• Geographic and institutional context for the patient group is unspecified.
