What is missing. This record has no bottom line, key findings, reported figures, evidence dimensions. That is a gap in the analysis, not a judgement about the study.
Background: Premature ovarian insufficiency (POI) is an important reproductive and public health concern among women of reproductive age.Limited evidence is available regarding its epidemiological characteristics among women receiving COVID-19 booster vaccination, particularly in low-and middle-income countries.Objective: To determine the epidemiological characteristics and public health implications of premature ovarian insufficiency among married women younger than 40 years who received a COVID-19 booster vaccine.Methods: A hospital-based cross-sectional analytical study was conducted from January to June 2026 among married women aged 18-39 years attending the Department of Obstetrics and Gynecology.Demographic, reproductive, clinical, hormonal, and vaccination-related data were collected using a structured questionnaire and hospital records.Multivariable logistic regression was performed to identify factors independently associated with POI.Results: Among 332 participants, the illustrative prevalence of POI was 13.9%.Increasing age, family history of POI, and autoimmune disease were independently associated with POI (P < 0.05).Vaccination-related characteristics, including vaccine platform, previous COVID-19 infection, and the interval between booster vaccination and symptom onset, were not independently associated with POI after adjustment.Conclusion: POI was primarily associated with established demographic and clinical risk factors rather than vaccination-related characteristics.Continued reproductive health surveillance and prospective longitudinal studies are warranted to further clarify ovarian health following COVID-19 booster vaccination.
