Adding sugar to children’s beverages: a theory of planned behavior study of Lebanese mothers

This study, guided by the theory of planned behavior (TPB), aimed to investigate whether attitude, subjective norms, and perceived behavioral control can predict parents’ intentions to reduce or stop adding sugar to their child’s beverages, such as tea or milk. The research also seeks to determine the predictive power of the TPB on the actual behavior of parents in reducing or halting sugar intake in their children’s drinks. A questionnaire was developed to assess sweetening beverage behavior variables by mothers of children aged 3–7 years attending Lebanese public schools, with 184 responses retained with no missing values for analysis. Regression analysis was utilized to examine determinants of self-reported practice and intentions regarding sweetening beverages. Results showed that attitude and perceived behavioral control were significant predictors of intention to reduce or stop adding sugar to a child's beverages. The perception of behavioral control was found to predict the behavior of adding sugar to a child’s beverages, even though the intention to reduce or stop did not. The study findings suggest that individuals with low perceived behavioral control and strong habits would be more likely to be actual performers of the adding sugar behavior regardless of their intention level. When adding sugar to a child’s beverages is a common parental habit in low-income Lebanese families, our findings offer valuable insights for developing culturally and socially tailored health promotion strategies to reduce or stop adding sugar to children’s beverages and raise parental awareness about the health risks associated with excessive sugar consumption in children.
