Abstract： Objective:To analyze the effects of the Smart Health Hut in the health management of an workplace population with prehypertension.Methods:One-hundred and fifty-four employees with prehypertension recruited from an enterprise were randomly divided into the experimental and control groups in May 2019. The intervention group patients had accurate health management based on the Smart Health Hut for eight weeks, and those in the control group were with a traditional health education brochure. Group t-tests compared blood pressure differences, self-management ability in various dimensions, and the total scores between the two groups. Matched pairs t-tests compared those differences between before and after intervention in the same group. Results:There was no statistically significant difference between the two groups before intervention. After the eight-week intervention, the total score, the scores of self-management behavior, cognition, and the environment of the experimental group were significantly higher than in the control group [(107.75±9.21) vs (97.38±6.99), (53.27±5.81) vs (48.59±4.93), (33.44±4.27) vs (31.63±3.42), (21.04±3.14) vs (17.16±2.30)]. Systolic blood pressure and diastolic blood pressure in the experimental group were significantly lower than those in the control group [(124.01±4.60) vs (126.88±3.52), (78.41±5.93) vs (80.53±4.89)], and the difference was significant.Conclusion:The Smart Health Hut can significantly improve the workplace population′s self-management ability with normal high blood pressure and control their blood pressure.
