Combination of health education tools and health literacy intervention: on the basis of the control group, the hypertension health education tools are used as the education media to encourage patients to find out the elements of the tool chart, use the picture content to guide the topic development, encourage patients to discuss with each other, realize heuristic questions, rather than a single indoctrination, so as to deepen the understanding and memory of patients. At the end of the course, patients are encouraged to set short-term goals to encourage behaviors that continue to achieve larger goals. At the same time, health literacy lectures were organized during the hospitalization. Health literacy lecture is mainly to learn the information that hypertension needs to pay attention to in order to improve the health literacy of hypertension patients and other indicators.

No intervention except conventional care were performed for the control group

On the basis of the control group, the intervention measures to improve the health literacy of patients were implemented and self-made health education tools were used. During hospitalization, health knowledge lectures shall be organized for patients. Before the activity, the theme of the activity shall be clarified. Each participant shall be organized by the educator to sit on the tool chart in a U-shape. According to the theme of the tool map, patients interact with educators. And learn the knowledge content related to hypertension health literacy. Before the end of the activity, the educator will review all the contents discussed in the activity quickly, answer the questions in the activity, and help the participants to sort out and consolidate the knowledge acquired in the education. Follow up intervention for patients after leave hospital.

The scale consists of 15 items and 5 dimensions, with a total score of 0-60. One score will be given if one question is answered correctly. The higher the score is, the higher the HL level is. According to the TOFHLA classification standard, HL level is divided into three levels. If the score is less than 32, the HL level is deficient; if the score is 32-40, the HL level is critical; if the score is more than 40, the HL level is sufficient. The score of the scale before and after the intervention was compared.

The decrease of systolic and diastolic blood pressure in hypertension patients after health literacy intervention

According to 2008 WHO guidelines, BMI < 25 kg / m2 is normal weight or low weight, 30 kg / m2 > BMI ≥ 25 kg / m2 is overweight, BMI ≥ 30 kg / m2 is obesity. To evaluate the changes of BMI of patients before and after intervention

WC ≥ 102CM in male and 88cm in female were abdominal obesity, 94cm ≤ male WC < 102CM, 80cm ≤ female WC < 88cm are abdominal overweight, WC < 94cm in male and 80cm in female is normal.To evaluate the changes of WC of patients before and after intervention

The scale consists of 41 items and uses the five point equidistant scoring method. The scores are 1, 2, 3, 4 and 5 in turn. The total score of the scale is between 41 and 205. The higher the score, the better the quality of life.Compare the changes of the scale scores before and after the intervention
