Health belief model based evaluation of school health education programme for injury prevention among high school students in the community context

PurposeThe purpose of this paper is to determine the effectiveness of a modified HBM-based intervention to reduce body mass index (BMI) for age in overweight junior high school students.Design/methodology/approachA cluster-randomized controlled trial was conducted in the first and second years of a junior high school in the center of Thailand. In total, 24 classrooms were randomly assigned to a modified health belief model intervention arm (HBMIA), and 24 classrooms were randomly assigned to a traditional school health education arm (control). In total, 479 students who were overweight (BMI forage = median +1 SD, aged 12–15 years) participated in the study. The HBMIA used the health belief model (HBM) as a motivator for behavioral strategies that included modifying diet and participating in physical activity. BMI, health knowledge and behavior for preventing obesity were recorded at baseline and at six months. A multilevel regression model was performed to calculate mean difference between HBMIA and control group.FindingsThe students who participated in the HBMIA showed a decrease in BMI of 1.76 kg/m2, while those who participated in the control showed an increase in BMI of 1.13 kg/m2, with a mean difference of –2.88 kg/m2(95% CI =–3.01 to –2.75), an improvement in health knowledge (mean difference 27.28; 95% CI =26.15–28.41) and an improvement in health behavior (mean difference 23.54; 95% CI =22.60–24.48).Originality/valueA modified HBM-based intervention to reduce BMI for age is effective in overweight junior high school students.

Abstract Background The purpose of this study was to explore the predictors of smoking among high school students using health belief model (HBM). Methods In this cross-sectional study, participants were 425 boys (mean age was 16.7 ± 0.85 and ranged from 15 to 19 years) among high school students in Bandar-Abbas city. Data were collected using a researcher-made questionnaire consisted of two main sections: Socio-demographic characteristics and HBM constructs. The zero-inflated ordered probit (ZIOP) model was used for investigating the association between health belief model constructs and smoking behavior. Results Results indicated that 82% of participants never smoked cigarette at all. The results of ZIOP model showed that knowledge, susceptibility, severity, benefits and cues to action had significant effect (P < 0.05) on smoking cigarette after adjusting for other covariates (i.e age, parents’ education, losing one of the parents). Moreover, having a smoker friend was an inflation factor (P < 0.001). Adolescents with smoking friends are 44% less likely not to smoke at all. Conclusion Based on these findings, having a smoker friend, knowledge, susceptibility, severity, benefits and cues to action have a key role in predicting smoking and should be considered in designing educational programs aiming at reducing smoking initiation among adolescents.
