Background: Inadequate fruit and vegetable (FV) consumption is a serious public health issue in children and adolescents that is influenced by the type of parenting style and one’s self-efficacy.

Purpose: The purpose of the study was to determine the association between parenting style and adolescent FV consumption and whether adolescent self-efficacy mediates this relationship.

Methods: Data retrieved from the Family, Life, Activity, Sun, Health, and Eating (FLASHE) study were used to perform statistical analyses on 1,382 parent – adolescent dyads. A mediation analysis using the causal steps approach was used to determine whether adolescent self-efficacy mediated the effect of parenting style on adolescent FV consumption. Multiple linear regression and binary logistic regression were used, adjusting for confounding due to demographics.

Results: There was a significant positive association between authoritative parenting style and adolescent FV consumption (B = .127, 95% CI = .052, .203, p = .001); however, after controlling for adolescent self-efficacy, the parenting style effect was attenuated and no longer statistically significant (B = .061, 95% CI = -.011, .133, p = .095). The reduction in the beta coefficient indicated a partial mediation of self-efficacy on the association between parenting style and adolescent FV consumption.

Conclusion: The study showed a positive significant association between authoritative parenting and adolescent fruit and vegetable consumption, partially mediated by adolescent self-efficacy. More authoritative parenting was associated with greater adolescent FV consumption. Healthcare professionals should encourage parents to practice an authoritative parenting style and emphasize the benefits associated with parental support and affection.
