abstract

  • OBJECTIVES: To estimate the association between rural residence and sequelae of hypertensive disorders of pregnancy (HDP) in the first year postpartum. STUDY DESIGN: We used the Maine Health Data Organization's All Payer Claims Data to identify women with HDP who delivered during 2007-2019 and did not have chronic hypertension or pre-pregnancy cardiac conditions (n = 8882). We used Cox proportional hazards modeling to estimate rural-urban hazard ratios (HR) and 95% confidence intervals (CI), adjusting for HDP subtype, age, insurance, nulliparity, and co-morbidities. Results were stratified by HDP subtype and timing of acute care visits. MAIN OUTCOME MEASURES: Risk of at least one emergency room or inpatient visit related to hypertension or cardiovascular conditions in the first year postpartum and receipt of outpatient antihypertensive medications from 4 days to 1 year postpartum, separately. RESULTS: Overall, risk of at least one acute care visit in the first year postpartum was not different between rural vs urban women (4.2% vs 4.2%; adjusted HR 0.98; 95% CI 0.79,1.21), and outpatient receipt of antihypertensive medication was not different (12.9% vs 12.8%; adjusted HR 0.99; 95% CI 0.87, 1.12). However, stratified analyses suggested some differences (e.g. preeclampsia with severe features: acute care visit adjusted HR 1.54; 95% CI 0.95, 2.49). CONCLUSIONS: Rural and urban women do not differ in the risks of these common HDP sequelae, though rural women may have increased risk by HDP subtype or timing of acute care visit. Future research should investigate postpartum interventions for reducing HDP sequelae in rural and urban women.
