简要总结

This study aims to examine the effects of added sugar warning labels for sugar-sweetened beverages (SSBs) on explicit weight bias and body weight attributional judgements. Participants will be assigned to view either control labels or added sugar warning labels applied on SSBs in an experimental store. Participants will shop for beverages in the store and take a computer survey during four visits to the store, spaced approximately one week apart.

详细描述

This study aims to determine whether applying added sugar warnings on sugary drinks impacts explicit weight bias and body weight attributional judgements. Approximately 543 adults (ages 18 and older) who have bought at least one SSB in the past week will attend four in-person visits at an experimental store, spaced approximately one week apart. Participants will be randomized to see either neutral control labels or added sugar labels on SSB containers during their visits to the experimental store. At each study visit, participants will shop for beverages in the store and take a computer survey. Explicit weight bias and attribution of responsibility for body weight will be assessed via the computer surveys at the first and last visit.

结局指标

主要结局

Explicit weight bias, mean score

时间窗: Assessed via survey after exposure to intervention (i.e., shopping task) 2 times approximately 4 weeks apart (i.e., in visits 1 and 4)

Explicit weight bias will be measured by survey through seven items. Items will present participants with pairs of antonyms and ask that they select the box between antonyms that they feel best describes their feelings and beliefs about people with obesity: (1) lazy - hard-working, (2) no will power - has will power, (3) good self - control - poor self-control, (4) active - inactive, (5) self-indulgent - self-sacrificing, (6) dislikes food - likes food, (7) undereats - overeats. Response options, which will be presented as 5 boxes between antonyms, will be coded in a categorical 1-5 range, where higher scores represent higher endorsement of a stereotype that contributes to weight bias. Each participant's responses to each item will then be averaged across the seven items to obtain their final score on the outcome in a 1-5 range, where higher scores represent higher explicit weight bias.

次要结局

  • Body weight attributional judgements, mean score(Assessed via survey after exposure to intervention (i.e., shopping task) 2 times approximately 4 weeks apart (i.e., in visits 1 and 4).)
