Abstract
Introduction and Objective: Perception is the most important predictor of behavior and
there is a strong relation and correlation between behavior and believes. Thus, to improve
self‑care behaviors of patients, it is required to fully understand their perceptions about
behavior. This paper aimed to assess the prediction power of health promotion model
of systolic blood pressure (SBP) as the result of self‑care behavior in rural hypertensive.
Methods: This cross‑sectional study has been carried out through random multistage
sampling on 671 rural patients under the coverage of health center of Ardebil city in
2013. Data were collected through reliable and valid questionnaire based on the health
promotion model in eight sectors. For data analysis, Pearson correlation statistical
tests, multivariate linear regression, ANOVA and independent t‑test were used and for
confirmatory factor analysis, SPSS 18 and AMOS 18 (SPSS Inc., Chicago, IL, USA) were
used. Results: The results showed significant negative correlation between self‑efficacy,
perceived benefits, situational influences, affects related to behavior and commitment to
action structures with SBP and showed a positive significant correlation between perceived
barriers and SBP. Furthermore, age and body mass had direct significant relation with SBP.
The age of patients showed inverse significant correlation with self‑efficacy, perceived
benefits, affects related to behavior, interpersonal influences and commitment and showed
a direct significant correlation with perceived barriers, means that by increase of age,
the perceived barriers also increased. The structures of health promotion model have
in overall the prediction power of 71.4% of SBP changes. Conclusion: The diet perceptions of patients, the same as health
promotion model, has good predictive power of SBP, especially the structures
of perceived benefits and self‑efficacy have inverse meaningful relation with
systole blood pressure and predicted a higher percentage of this variable.
