Social and cognitive predictors of fruit and vegetable intake among adolescents: The context of changes in body weight


Komorowska Szczepanska, Wanda; Scholz, Urte; Liszewska, Natalia; Luszczynska, Aleksandra (2013). Social and cognitive predictors of fruit and vegetable intake among adolescents: The context of changes in body weight. Journal of Health Psychology, 18(5):667-679.

Abstract

Two studies investigated differences in the relationships between adolescents' fruit and vegetable intake (FVI) and the predictors specified in the Health Action Process Approach and Social-Cognitive Theory. Retrospective (Study 1; N = 502) and prospective (Study 2; N = 668) designs were applied. Among adolescents with overweight/obesity, intention was cross-sectionally associated with FVI (Study 1); no social or cognitive predictors explained FVI at 14-month follow-up (Study 2). The planning - FVI and self-efficacy - FVI relationships were stronger among adolescents who reduced their body weight to normal, compared to effects observed among those who maintained their body weight (Studies 1 and 2).
