简要总结
The purpose of this study is to evaluate how food commercials influence food choices in children and their parents.
详细描述
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.

结局指标
主要结局
Food Choice Change
时间窗: 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
时间窗: 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
时间窗: 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.
