“…Thus, designing appropriate school-based health promotion and education interventions relying on the assessment of behavioral intention among school students can lead to healthier children fostering regular healthy dietary practices in their homes and communities. Similarly, Char et al ( 32 ), in their systematic review focused on South Asia, noted that technology-based interventions had a beneficial effect on dietary behavior outcomes. The application of digital technology can aid in the designing and implementation of cost-effective interventions regarding the dietary behavior of adolescents.…”

IntroductionAdolescence is a distinctive period of life when intense physical, psychological, and cognitive development occurs. A healthy diet helps prevent various forms of malnutrition and non-communicable diseases (NCDs) like diabetes, heart disease, stroke, and cancer. The current study aimed to assess the change in behavioral intentions (measured based on the TPB) toward healthy dietary practices through health promotion intervention among adolescents studying in selected schools in an urban area of West Bengal, IndiaMethodsThe current study was a non-randomized controlled interventional study conducted among adolescents in either seventh, eighth, ninth, or tenth grades and aged between 12 and 16 years. Two-step cluster analysis with maximum likelihood estimation identified the intenders of a healthy diet. The intervention effect was measured using Relative Risk (RR) for being in the higher intention cluster through Generalized Linear Model (GLM) with a log-linear link under Poisson distribution assumptions and robust standard errors. A P-value of 0.05 or lesser was considered statistically significant.ResultsThere was no statistically significant difference in the mean score of “Attitude” in both groups. The mean score of “Subjective Norm” among the intervention group increased after intervention, and the difference was statistically significant. The mean score of “Perceived behavioral control” in the intervention group increased after the intervention, but the difference was statistically not significant. The intervention group's post-intervention proportion of intenders increased, and the difference was statistically significant. The relative risk of becoming an intender for healthy diet consumption in the Intervention group compared to the Control group was 2.07 (1.44–2.97).ConclusionsThe intervention package effectively brought about a positive change in behavioral intention toward healthy dietary practices among adolescents. Model-based and construct-oriented intervention packages can be adopted in school-setting to promote behavioral intention toward a healthy diet.

AimThe research was conducted to measure the effect of health literacy‐grounded web‐based education program on health literacy, nutrition and exercise behaviours in adolescents.BackgroundThe increasing prevalence of obesity in adolescents is explained by a sedentary lifestyle and unhealthy diet. Health literacy is essential for adolescents to maintain their healthy behaviours.MethodsThe research was conducted as a parallel group randomized controlled trial. The study was completed by 114 adolescents (experimental = 42, control = 72). The Personal Information Form, the Health Literacy Scale for School‐Age Children and the Nutrition and Exercise Subscales were used to collect data. A web‐based education program was implemented. Two‐way mixed design ANOVA with Bonferroni test was used to examine the group, time and group * time interaction of the measurements.ResultsThere was no statistically significant difference between the experimental and control groups regarding health literacy level, nutrition and exercise behaviours pre‐test mean scores (p > 0.05). In the post‐test, the mean scores of health literacy and nutrition behaviours in the experimental group were higher than the control group (p < 0.001). However, there was no significant difference in exercise behaviours (p > 0.05). The power and effect size in mean scores changes for health literacy (99.8%, η2 = 0.039) and nutrition (99.8%, η2 = 0.039) were moderate.ConclusionThe study concluded that health literacy‐grounded web‐based education program increased the health literacy levels of adolescents and improved their nutritional behaviours; however, there was no sufficient change in exercise behaviours.
