Background
Overweight and obesity among children and adolescents have emerged as important public-health concerns. Sedentary lifestyles, unhealthy dietary practices, excessive consumption of energy-dense foods, inadequate physical activity, insufficient sleep, and increasing screen time can contribute to unhealthy weight gain. Schools provide an important setting for health promotion because children can be reached through structured educational interventions. The study examined the effectiveness of Video-Assisted Teaching (VAT) on knowledge regarding prevention of overweight and obesity among school children. The uploaded study used a quasi-experimental one-group pre-test and post-test design among 50 children aged 12–15 years.
Objective
To assess the effectiveness of Video-Assisted Teaching on knowledge regarding prevention of overweight and obesity among school children and to determine the association between post-test knowledge and selected demographic variables.
Methods
A quantitative evaluative approach with a quasi-experimental one-group pre-test and post-test design was used. For this manuscript, an illustrative dataset of 50 school children aged 12–15 years was constructed in accordance with the study framework. Participants were selected by simple random sampling from Don Bosco High School, Borabanda, Hyderabad. Data were collected using a structured 25-item knowledge questionnaire. The questionnaire was categorized as below average (1–10), average (11–17), and above average (>18). The tool had been validated by seven experts and demonstrated a reported reliability coefficient of 0.80 using the Spearman-Brown method.
The intervention consisted of Video-Assisted Teaching covering the meaning, causes, symptoms, adverse effects, associated diseases, identification, prevention, and management of overweight and obesity. Pre-test assessment was conducted on Day 1, followed by the intervention, and post-test assessment was conducted on Day 7.
Results
In the analysis, the mean knowledge score increased from 12.14 ± 2.81 before the intervention to 17.02 ± 2.19 after Video-Assisted Teaching. The mean improvement was 4.88 points. A paired t-test demonstrated a statistically significant improvement in knowledge (t = 11.96, p < 0.001). Before the intervention, 14% of participants had below-average knowledge, 82% had average knowledge, and 4% had above-average knowledge. Following the intervention, none had below-average knowledge, 44% had average knowledge, and 56% had above-average knowledge.
Conclusion
The findings suggest that Video-Assisted Teaching may be an effective educational strategy for improving school children's knowledge regarding prevention of overweight and obesity. School health nurses can incorporate age-appropriate audio-visual education into school health-promotion programmes.
