Abstract :
Background The number of reported food illnesses in Iran has
increased over the past 10 years. Objectives The present study aimed at
investigating the effect of education, based on the transtheoretical
model (TTM) and the theory of planned behaviour (subjective norm and
perceived behavioural control), on reducing fast food consumption in
obese Iranian female adolescents. Methods In this quasi-experimental
study, data were collected through a survey. This study included 420
obese Iranian female adolescents, aged 15 to 18 years, who were gathered
from 12 schools in city of Sabzevar in Iran during 2014 tand 2016. Using
a questionnaire, the demographic and anthropometric characteristics,
transtheoretical model (TTM) constructs, subjective norm, and perceived
behavioural control were measured and analysed. Results The average
rates of perceived behavioral control (11.949 ± 2.876), subjective norms
(16.515 ± 4.877), stages of change (6.355 ± 1.342), processes of change
(8.614 ± 3.406), and self-efficacy (22.447 ± 6.783) in the education
group were meaningfully increased (P value < 0.05); however,
these changes were not meaningful in the control group (P value >
0.05). Also, no statistically meaningful difference was obtained in
decisional balance between the 2 groups after the intervention (P =
0/924). Conclusions The results of this study suggest that the use of
TTM (except with decisional balance) focuses on the perceived
behavioural control, and subjective norms can be used in educational
interventions and have useful results.
