Decision-making for Food Consumption in Young Adults

Status Active, not recruiting

Clinical Trial Summary

Background: Experimental and cross-sectional evidence suggests that poor executive function can lead to heightened reactivity to food cues and perceived greater reward of unhealthy but palatable foods and subsequently lead to overeating or clinical eating disorders. This may be an important reason for the increasing trend of obesity in our society. Aims: This study will investigate the interrelationships among executive function, reactivity to food-related cues and eating style in young adults. In addition, this study will examine the influence of food environment and stress on reactivity to food-related cues and executive function and how executive function and reactivity to food-related cues would influence health risky behaviours in young adults. We will also conduct a pilot randomized control trial (RCT) to develop the culturally specific goal priming intervention for the Chinese adults and test its effect on decision-making for food choice among adults with low executive function. Design and subjects: This will be a three-wave cohort study in young adults who are recruited in their final-year of first post-secondary education and follow-up at six months and 12 months after their graduation. For the pilot RCT, a 2 (low vs. high executive function) x 2 (with vs. without goal priming intervention) will be used to test the effect of goal priming intervention on food choice. The goal priming intervention will be 5-min word-searching task to prime goals of healthy eating. Main outcome measures: Participants will be invited to complete a series on computerized tasks and other assessments online in each wave to assess their executive function, risk taking propensity, reactivity to food-related cues, perceived stress, exposure to food-related cues, eating style and other health-related behaviours. Structural equation modelling will be used to test the interrelationships among executive function, reactivity to food-related cues and eating style, among exposure to food-related cues, perceived stress and reactivity to food-related cues, and among executive function, reactivity to food-related cues, risk taking and adoption of health-related behaviours. For the pilot RCT, the effect of intervention on tendency of choosing healthy and low-calorie foods will be evaluated using logistic regression model with level of executive function and goal-priming intervention as the main between-group factors.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
