Using theory of planned behavior to predict healthy eating among Danish adolescents

Abstract

Purpose - The objective of the study was to apply the Theory of Planned Behavior to predict Danish adolescents’ behavioural intention for healthy eating. <br/>Design/methodology/approach - A cluster sample survey of 410 students aged 11 to 16 years studying in Grade 6 to Grade 10 was conducted in Denmark. <br/>Findings - Perceived behavioural control followed by attitudes were the most important factors in predicting behavioural intention. Females and adolescents with a higher BMI were also found to have a stronger behavioural intention. Healthy eating was perceived to be beneficial and useful, and, to a lesser extent, interesting and desirable. Family, TV programmes, and teachers were influential socialization agents. <br/>Research limitations – The survey responses may be affected by a social desirability bias. The survey includes a non-probability sample and results may not be generalized to all Danish adolescents. <br/>
