To assess quantity and quality of nutrition and food safety information in science textbooks prescribed by the Central Board of Secondary Education (CBSE), India for grades I through X.
Design:
Content analysis.
Methods:
A coding scheme was developed for quantitative and qualitative analyses. Two investigators independently coded the data and inter-coder reliability was assessed using Cohen’s Kappa. The inferences were then reviewed by an expert group.
Results:
There was high agreement (Kappa = 0.89) between coders. Nutrition topics got > 10% pages in textbooks of grades I to VII, while they were omitted in subsequent grades. Food safety got a mere 1% of page allocation only in grades I to III books. Over 25% of biology illustrations related to nutrition in grades I, II and IV but not in others. Nutrition topics in textbooks beyond grade IV were repetitive and inconsistent. Some illustrations depicted uncommon foods and had urban bias.
Conclusions:
Nutrition and food safety content in science textbooks is low. Important topics such as nutritional needs during adolescence, obesity, unhealthy foods and food labelling are not covered. These findings provide direction for strengthening textbook content to promote nutrition education in schools.
