Adolescent screen-viewing behaviour is associated with consumption of sugar-sweetened beverages: The role of habit strength and perceived parental norms

The association between adolescent screen-viewing behaviour (i.e., television viewing and computer use) and the consumption of sugar-sweetened beverages was studied in a Dutch sample of adolescents (N = 383) using self-administered questionnaires. In particular, the previously understudied role of habit and perceived parental norms in the execution of these behaviours was investigated. Results showed that screen-viewing behaviour was associated with consumption of sugar-sweetened beverages (r = .32). Habit strength of both behaviours correlated with a large effect size (r = .50). The interaction between both behaviours was underlined by the finding that consumption of sugar-sweetened beverages was explained by perceived parental norms regarding screen-viewing behaviour (beta = .12; adjusted for the behaviour and perceived parental norm regarding sugar-swcetened beverage consumption). Consequences of the identified role of habit and parental norms in the interplay between sedentary behaviour and consumption of sugar-sweetened beverages among adolescents are discussed.
