Age at Menarche and Risk of Hypertensive Disorders of Pregnancy: A Retrospective Cohort Study
Description
This dataset originates from a retrospective cohort of pregnant women who received obstetric care at a tertiary care hospital in Mexico City between January and December 2024. It includes anonymized clinical, sociodemographic, and reproductive data used to evaluate the association between age at menarche and the occurrence of hypertensive disorders of pregnancy (HDP), including gestational hypertension, preeclampsia, and eclampsia. The dataset contains variables on maternal age, education, marital status, household income, parity, history of miscarriage, family history of hypertension or diabetes, age at menarche (continuous and categorized), gestational diabetes status, BMI category (estimated pregestational BMI), lifestyle behaviors, and outcomes related to HDP. Hypertensive disorders were obtained directly from medical records and classified according to routine clinical diagnoses assigned during prenatal and intrapartum care. No personal identifiers (names, addresses, dates of birth, medical record numbers) are included. All data were fully de-identified prior to uploading.
