Investigation into Differences in Level of Knowledge about Hypertension between High School Students and Elderly...

As a major chronic non-communicable disease, hypertension is the most important risk factor for cardiovascular disease, chronic kidney disease, stroke and, if not treated appropriately, premature death. A population-based approach aimed at decreasing high blood pressure among the general population is an important component of any comprehensive plan to prevent hypertension. However, few studies have investigated generational differences in knowledge about, and consciousness of, hypertension. Thus, we conducted a questionnaire survey about hypertension, with the aim of clarifying differences of understanding about hypertension between high school students and elderly people. The results of this investigation suggested that there is indeed a generational difference: knowledge about hypertension, and awareness of its relationship with salt intake, was higher in elderly people than in high school students. Furthermore, our study showed that among high school students, salt intake consciousness correlated with a family history of hypertension. By contrast, in elderly people, salt intake consciousness is related to age and to an awareness of recommended daily salt intake. This study strongly showed that knowledge and consciousness of hypertension varied among generations, with the elderly being more aware and conscientious about salt intake. Acknowledgement of this generational diversity is critical to developing an effective overall preventive strategy for hypertension.
