ABSTRACT
BACKGROUND: The influence of western lifestyle such as high-caloric dense food and sedentary lifestyle has a great influence on Indian children, and the current prevalence of childhood overweight in India ranges between 4% and 22%. The primary aim of the study was to determine the change in growth parameters (waist circumference) as well as dietary behaviors at baseline and at the end of first, third, sixth, and ninth months among overweight adolescent girls and boys following a school-based nutritional education program. MATERIALS AND METHODS: The study was conducted in 2019 in four urban schools at Puducherry which were randomly assigned to study and control groups by lottery method, and 140 overweight children aged 11-14 years were in the study group and 140 children were in the control group. Simple random sampling method was used to select the samples A nutrition education program highlighting the importance of balanced nutrition and the ill effects of obesity was imparted to students in the study group through a PowerPoint presentation. As a means of reinforcement, posters and pamphlets were distributed. The waist circumference and the mean calorie, protein, and fat intake were assessed at baseline and at the first, third, sixth, and ninth months and compared between groups using independent t test. RESULTS: There was a statistically significant reduction in waist circumference in the study group when compared to the control group at P < 0.05. A significant decrease in the calorie intake at P < 0.001 and fat intake at P < 0.01 was observed in the study group. The protein intake in the study group increased at the end of 9 months, which was significant at P < 0.001. CONCLUSION: School-based nutritional education program has been found to be a successful intervention in controlling unnecessary weight gain among overweight adolescents.
ABSTRACT
Background: Globally, the prevalence of overweight and obesity has dramatically increased in the recent years. In India, more than 10% of schoolchildren are overweight or obese. Schools play a major role in the modification of behavior. The aim of this study was to assess the effectiveness of after-school physical activity intervention on body mass index (BMI) and waist circumference/height ratio as primary outcomes. Materials and Methods: A randomized controlled trial was adopted where the schools were randomized. Each group, i.e., study and control groups, had 140 overweight adolescents. BMI and waist circumference/height ratio were measured. After-school physical activity intervention was carried out for a period of 9 months by the study group. The posttests were carried out at an interval of 3 months up till 9 months. Results: There was a statistically significant difference in BMI between the study and control groups during the 6th and 9th months (t = 1.256, P < 0.001 and t = 0.920, P < 0.001), respectively. The repeated measures analysis of variance did not show a significant reduction in BMI and waist circumference/height ratio over a period of time. Conclusion: School-based physical activity interventions are effective in prevention of childhood overweight/obesity and are a very cost-effective measure that can be easily implemented in schools.
ABSTRACT
BACKGROUND: Blended learning (BL), the integration of online with face to face teaching, is established as a teaching method in higher education. Understanding the learner's readiness toward online component of BL is important in designing and delivering BL. Nursing students require proficiency in interpersonal relationship and social interaction apart from knowledge and skills. BL may provide an opportunity to acquire the professional skills better than the traditional face to face sessions. The objectives of this study were to identify the nursing student's readiness toward BL and perceptions about the online learning component of BL. MATERIALS AND METHODS: First- and second-year entry level graduate nursing students of Sri Ramachandra Institute of Higher Education, Chennai, India, were the participants of the study. This study used a mixed method approach. An online questionnaire, developed based on the literature and expert consensus, was used in the first phase. A focus group discussion (FGD) with ten random participants of the survey was conducted to understand the perceptions and readiness to adopt the online component of BL. The present study was conducted from December 2019 to January 2020. Survey results were analyzed through descriptively. Content analysis was carried to summarize FGD results. RESULTS: A total 158 students of entry level nursing graduate programme participated in the survey. 53.8% of felt BL will have positive effect on their learning and 70% of the respondents were ready to adopt BL. The FGD identified two themes: (I) Readiness to adopt online learning as a component of BL and (II) perceived barriers and challenges in adopting online contents. CONCLUSION: Entry level nursing graduate students had a positive perception about the online components. Majority of them are confident in accessing the online contents. Willingness to learn through online, previous experience with online learning, and perceived advantages of online component might influence the learner's readiness. Availability of internet and absence of teachers were perceived as the barriers to online learning by the participants.
