Stage-matched nutrition guidance: stages of change and fat consumption in Dutch patients at elevated cardiovascular risk.

Objective: To assess the effects of stage-matched nutrition counseling on stages of change and fat intake.

Design: Controlled clinical trial.

Setting: 9 family practices in a family medicine practice network.

Nutrition guidance in Dutch family practice: behavioral determinants of reduction of fat consumption.

Background: Studies have shown that the psychosocial determinants attitude, self-efficacy, subjective norm, and health threat are important in predicting intention to change fat consumption. However, the role of habit in relation to these determinants is still largely unknown.

Objective: We aimed to assess whether and how habit influences intention in relation to attitude, self-efficacy, subjective norm, and health threat.
