Abstract
The objectives of this study were to evaluate the effectiveness of health screening and education for
prediabetes and prehypertension individuals by randomized controlled trial. The samples were randomized
into an experimental group that received health education and a control group that had not received
follow-up for two months. Outcomes were the modifying of health behaviors, blood pressure, fasting blood sugar (FBS) and knowledge. There were 367 participants who attended the health-screening process;
6.56 percent were prediabetes, 33.75 percent prehypertension and 13.75 percent prediabetes and
prehypertension. Thirty-one of the prediabetes (15 in the experimental group and 16 in the control group)
and 49 of prehypertension (24 in the experimental group and 25 in the control group) were followed up.
The result showed that eating, alcohol drinking and exercise behavior of those who were prehypertensive
individuals in the experimental group were significantly changed (P-value <0.05) and that eating salt and
drinking alcohol among those who were prediabetic significantly decreased (P-value <0.05). Blood pressure
levels and FBS were significantly decreased from the baseline (P-value <0.05) in both experimental
groups but there was no difference in the control group. The knowledge scores were significantly higher
in the experimental group than in the control group (p-value <0.05). The results indicated that effectiveness
of health screening and education for prediabetes and prehypertension individuals could help subjects
realize the need to modify their health behaviors and reduce blood pressure and blood sugar levels.
