Abstract
OBJECTIVES: To estimate the incidence of hypertension and the trend of systolic and diastolic blood pressure changes and relating factors influencing women with and without prior preeclampsia (PE). STUDY DESIGN: This prospective population based study included a total of 3022 eligible women (355 with PE and 2667 non-PE) recruited from participants of the Tehran Lipid and Glucose Study (TLGS) who were assessed for progression to subsequent hypertension over 15-year follow up. Pooled logistic regression model was utilized to estimate odds ratio (OR) of hypertension. The generalized estimating equation (GEE) was used to evaluate the trend of changes in hypertension parameters over time. RESULTS: At the end of follow-ups, 109 women (30.7%) in the PE group and 575 (21.5%) in the non-PE group had hypertension. The total cumulative incident rate of hypertension was 34/1000 person-years for PE groups and 22/1000 person years for non-PE groups (P < 0.001). Pooled logistic regression analysis showed that compared to non-PE women, OR of hypertension progression in women with PE was 3.70 after adjustment for age, body mass index (BMI), parity, triglycerides (TG) and high-density lipoprotein (HDL-C) (P-value < 0.001). Based on GEE analysis, mean changes of systolic and diastolic blood pressure in PE women increased by 4.66 and 2.55 mmHg, respectively, compared to the non-PE group, after adjustment for age, and BMI at baseline (P < 0.001), although the interaction term (follow-up year × PE) was not statistically significant. CONCLUSION: This study demonstrated increased chances of developing hypertension among women with prior PE, particularly in those who develop additional risk factors in their later life, compared to the non-PE women. While the trajectory of blood pressure change over time is similar between women with and without preeclampsia, women with a history of preeclampsia consistently have higher levels of blood pressure.
