Objectives; This study was conducted to identify medication adherence status and its predictors in soldiers with hypertension and suggest the useful data for intervention to improve soldiers' medication adherence. Methods; Using the structured questionnaires through researches' review, this survey was conducted at 8 military hospitals during July and August, 2018. The 134 respondents were explained about the survey and agreed to attend to the research. General characters were analyzed by statistical analysis, χ²-square analysis was conducted to compare the characters between adherence and non-adherence group and logistic regression analysis was done to identify the predictors. Results; Medication adherence soldiers in total respondent group were 71persons (53.0%) and non-adherence soldiers were 63persons (47.0%). As the result of χ²-square analysis, there were meaningful differences between two groups as age and education and we can see that medication adherence was relatively higher in 40s, 50s and high educated soldiers. Awareness score on the importance of medication was 1.7 and belief score was 1.4. and awareness score on the importance of medication(OR=1.709, ρ=0.14), belief on the drug effect(OR=1.494, ρ=0.34), the idea on medication's effect(OR=1.987, ρ=0.02) were statically meaningful. Conclusions; The percentage of medication non adherence soldiers' group was similar to previous researches' result and most of them were unintentional medication non-adherence cases. Awareness score on the importance of medication, belief on drug effect, the idea on medication's effect were statically meaningful so that we should focus on the three predictors for effective intervention to improve the soldiers' medication adherence.
