Area of Science:

  • Behavioral Science
  • Nutrition Science
  • Public Health

Background:

  • Understanding factors influencing fruit consumption is crucial for public health.
  • Dietary habits are complex and influenced by psychological and social determinants.

Purpose of the Study:

  • To identify predictors of fruit intake in a sample of 627 adults.
  • To examine the role of Theory of Planned Behavior constructs and habit strength in fruit consumption.

Main Methods:

  • Cross-sectional study with 627 Dutch adults.
  • Assessed predictors (attitudes, norms, self-efficacy, habit strength, intention) and fruit intake via validated questionnaires.
  • Employed hierarchical linear and logistic regression analyses.

Main Results:

Related Experiment Videos

  • Attitudes, subjective norms, self-efficacy, and habit strength significantly predicted intention to consume fruit.
  • Age, intention, and habit strength were significant predictors of actual fruit intake.
  • Theory of Planned Behavior constructs, habit strength, and self-efficacy were key determinants.

Conclusions:

  • Theory of Planned Behavior constructs effectively predict fruit intake.
  • Habit strength and self-efficacy are important additional determinants of fruit consumption.
  • Environmental change strategies should be explored in fruit promotion interventions.
