Background In recent years, more and more studies have shown that internet-based health management can help patients with hypertension control their blood pressure. However, there is a lack of similar research in China. Objective We designed this study to clarify the impact of long-term internet-based health management on the control of clinical parameters in patients with hypertension. These results are also expected to identify the relevant factors affecting the control of clinical parameters in hypertension more accurately toward developing more targeted health management strategies. Methods This was a longitudinal study of internet-based health management in the five provinces of northwest China. The inclusion criteria were aged ≥18 years and no serious cognitive disease or mental disorder. After collecting the physical examination data of 8567 people in the five northwest provinces in 2013, we conducted online health management (including diet, exercise, and behavior) and follow-up. In the physical examination in 2013, 1008 new patients with hypertension were identified, who were divided into a good blood pressure control group and poor blood pressure control group. Physical examination and a questionnaire survey were conducted every 2 years to understand the changes of health management on the subjects’ health-related behaviors. We then analyzed the changes of clinical indicators related to hypertension and the influencing factors related to blood pressure control in patients with hypertension. All statistical analyses were performed using R software (version 4.1.2) and a P value <.05 was considered statistically significant. Results A total of 8567 people met the inclusion criteria and underwent health management. Self-comparison showed that after 4 years of health management, the smoking cessation rate and amount of exercise significantly increased (both P<.001). The low-density lipoprotein-cholesterol levels also increased (P=.005), whereas the high-density lipoprotein-cholesterol levels decreased (P=.007). The newly discovered patients with hypertension in 2013 were further screened. After 4 years of health management, their smoking cessation rate increased significantly (P=.03) and the amount of exercise increased but not significantly (P=.08). In terms of clinical indicators, the diastolic blood pressure considerably decreased (P<.001) and the systolic blood pressure slightly decreased (P=.13). The correlation analysis of blood pressure control in patients with new-onset hypertension showed that gender (female) and changing relevant factors according to health management behaviors (BMI; cereals and potatoes intake; fish, livestock meat, and eggs intake; fruit intake; and physical activity) were the protective factors of blood pressure control. Conclusions Internet-based health management has a significant and long-term effect on blood pressure control in patients with hypertension.

UNSTRUCTURED Objectives We designed this study to clarify the impact of long-term Internet health management on the clinical parameters control on hypertensive patients. It is also expected to identify the relevant factors affecting the control of clinical parameters in hypertensive patients more accurately, to make health management more targeted. Methods This study is a part of the longitudinal study of Internet-based health management in the five provinces of Northwest China. After collecting the physical examination data of some people in the five northwest provinces in 2013, we conducted online health management (including health management in diet, exercise, behavior and so on) and follow-up. Relevant physical examination and questionnaire survey were conducted every two years to understand the changes of health management on the subjects' health-related behaviors, analyze the changes of clinical indicators related to hypertension and the influencing factors related to blood pressure control in patients with hypertension. Results The results showed that after four years of health management, the smoking cessation rate of participants was increased significantly (P < 0.001), the amount of exercise increased significantly (P < 0.001), and other health-related behaviors improved in varying degrees. Diastolic blood pressure (DBP) was significantly decreased in patients with new-onset hypertension (P < 0.001). The correlation analysis of blood pressure control in patients with new-onset hypertension found that gender (female) and changing relevant factors according to health management opinions (BMI, Cereals and potatoes intake, Fish, livestock meat and eggs intake, fruit intake, Physical activity) were the protective factors of blood pressure control. Conclusion Internet-based health management has a significant effect on blood pressure control in patients with hypertension, and its control effect is long-term.
