Effects of a Capacity Building Program for Village Health Volunteers on Knowledge and Sodium Consumption Behaviors Among Persons with Uncontrolled Hypertension
Keywords:Sodium consumption, A capacity building program, Village health volunteers, Uncontrolled hypertension
Sodium consumption behavior in people with hypertension is an important factor in controlling blood pressure levels. This quasi-experimental research investigated the effects of a capacity building program for village health volunteers on knowledge and behaviors related to sodium consumption among persons with uncontrolled hypertension. The sample consisted of persons with uncontrolled hypertension, consisting of one group which received knowledge from the village health volunteers who participated in the capacity building program and one group which received standard nursing care. Purposive sampling was used with 54 persons who were divided equally into the two groups (27 persons per group). The instruments utilized in the study included the capacity building program for village health volunteers based on the competency concept (McClelland, 1993), a lesson plan for village health volunteers, a book on eating less salt to control blood pressure, a successful model for village health volunteers, and a salt meter. The data collecting instruments consisted of two questionnaires: one on knowledge related to sodium consumption and one on sodium consumption behavior. The instruments were validated for quality and validity (IOC = .80, CVI = .80 respectively), and reliability (.87, .78 respectively) was acceptable. The data was then analyzed using Wilcoxon and the Mann Whitney U test.
The results showed that after the program, the group which received knowledge from the village health volunteers who participated in capacity development had significantly higher average scores for sodium consumption knowledge than before participating in the program, and more than those of the group which received standard nursing care (p < .001, p < .001 respectively). In addition, the mean score of sodium consumption behaviors for the group which received knowledge from the village health volunteers was significantly higher than before participating in the program and more than that of the group which received nursing care (p < .001, p < .001 respectively).
The results of this research point to the effect of the village health volunteers capacity development program and the use of the mentoring process to transfer knowledge. The group of people with uncontrolled hypertension had the knowledge and the ability to effectively modify sodium consumption behavior.
