The search will be conducted in the following databases, PubMed/MEDLINE, CENTRAL, LILACS, CINAHL, EMBASE, and WoS. Additionally, clinical trial records in ClinicalTrials and grey literatura in OpenGrey and Google Scholar. The search will include studies of health education intervention in knowledge and self-care practices about hypertensive disorders in pregnancy. All statistical analysis will be carried out with the Review Manager software. Data will be combined using random-effects models, binary data with odds ratios or relative risks, and continuous data using mean differences. Heterogeneity between studies will be assessed using the Q-Cochran test to measure the significance and the l2 statistic to measure magnitude. Discussion: This study will contribute to the knowledge of health interventions that are effective in guiding and educating pregnant women about the disease and self-care practices.
