Abstract：Objective To explore the curative effect of cognitive behavior intervention in patients with high-normal blood pressure. Methods The patients (n=60) were chosen from Apr. 2011 to Oct. 2011 as control group, and the patients (n=60) were chosen from Nov. 2011 to Apr. 2012 as intervention group. Control group was given routine nursing, and intervention group was given, besides of routine nursing, cognitive behavior intervention by telephone for one year. The content of intervention included changing life habits, proposing low-salt low-fat diet, banning smoking, limiting alcohol and increasing exercises. The awareness on lifestyle-related knowledge during the treatment and lifestyle changes were surveyed through questionnaire on the 2nd year. The medical examination reports were collected from two groups before and after intervention, and the content included blood pressure, fasting plasma glucose (FPG), blood fat, and measured height and weight on that day. The patients were followed up for one year and the effect of cognitive behavior intervention was reviewed in two groups. Results After systemic cognitive behavior intervention for one year, the awareness on lifestyle-related knowledge during the treatment was higher (90%vs. 73.3%, P<0.05), and population of high-salt diet (23.3%vs. 46.7%, P<0.05), high-fat diet (13.3%vs. 35.9%, P<0.05), smoking (25.0 vs. 48.3%, P<0.05) and drinking (30.0%vs. 36.7%, P<0.05) decreased, and population of insisting exercises (86.7%vs. 50.0%) increased in intervention group compared with control group. At the same time, the indexes of blood fat and FPG were improved (P<0.05). Conclusion The systemic cognitive behavior intervention can correct unhealthy lifestyle and improve metabolism level in the patients with high-normal blood pressure.
