Promoting Resilience to Food Commercials Decreases Susceptibility to Unhealthy Food Decision-Making

Not Applicable

Completed

Conditions: Obesity, Adolescent

Interventions: Behavioral: Control
Behavioral: Commercial Advertising Literacy Training

Registration Number: NCT04905498

Lead Sponsor: University of Kansas Medical Center

Brief Summary: The purpose of this study is to evaluate how food commercials influence food choices in children and their parents.

Detailed Description: The proposed research will investigate food decision-making in youth. Childhood obesity is a risk factor for health issues, thus preventing adverse effects of childhood obesity by promoting healthy eating habits and providing effective interventions are important. Television food commercials advertising calorie-dense and high in salt and sugar foods are known to contribute unhealthy food choices and obesity. Thus the proposed study will examine how the advertising intervention focusing on increasing advertising knowledge and changing affective attitudes toward commercials impacts susceptability to commercials and food decisions in youth.

Arm && Interventions

Group	Intervention	Description
Control	Control	Children were exposed to food commercials without narratives.
Intervention	Commercial Advertising Literacy Training	Children were exposed to narrative statements that were shown and read aloud in between commercials played.

Primary Outcome Measures

Name	Time	Method
Food Choice Change	Pre (day 0) and post intervention (day 7-10).	Children rated on a 4-point Likert scale (1-Strong No, 2-No, 3-Yes, 4-Strong Yes) about whether they would choose to eat 60 different foods (30 unhealthy, 30 healthy) on a computer program. Higher values for unhealthy foods represented unhealthier food choices and higher values for healthy foods represented healthier food choices. The mean scores for unhealthy food choices were compared between pre- and post-intervention, and the mean scores for healthy food choices were compared between pre- and post-intervention.
Food Tastiness Change	Pre (day 0) and post intervention (day 7-10).	Children rated on a 4 point Likert scale (1-Very Bad, 2-Bad, 3-Good, 4-Very Good) about how tasty 60 different foods (30 unhealthy, 30 healthy) were on a computer program. A regression coefficient (beta) of food taste was estimated at an individual level by fitting a linear regression model where taste and health ratings predicted food choices for each child. Higher estimated regression coefficients represented higher decision weights of food taste attributes in food choices. The mean estimated regression coefficients were compared between pre- and post-intervention.
Food Health Change	Pre (day 0) and post intervention (day 7-10).	Children rated on a 4 point Likert scale (1-Very Unhealthy, 2-Unhealthy, 3-Healthy, 4-Very Healthy) about how healthy 60 different foods (30 unhealthy, 30 healthy) were on a computer program. A regression coefficient (beta) of food healthiness was estimated at an individual level by fitting a linear regression model where taste and health ratings predicted food choices for each child. Higher estimated regression coefficients represented higher decision weights of food healthiness attributes in food choices. The mean estimated regression coefficients were compared between pre- and post-intervention.

Secondary Outcome Measures

Name	Time	Method
Level of Self-Control, as Measured by the Self-Control Scale	Children completed this item at the baseline visit (pre intervention).	Children completed the 36-item self-control scale. Each item is rated on a 5-point Likert scale from 1 (not at all like me) to 5 (very much like me). A total score (i.e., 36 response scores were summed) was computed for each child. The total score ranged between 36 (minimum) and 180 (maximum). The higher total score represented higher (better) perceived self-control. No subscales were used.
