Abstract:
This study examined the association between media and Instagram interaction patterns with weight bias among undergraduate nutrition students in the Brazilian Nutritionists\' Health Study. We also explored the potential mediating role of students\' own body image perception in these relationships. A total of 406 students (78% women) participated in this cross-sectional analysis. Sociodemographic data, media influence, Instagram interaction patterns, body image perception, and weight bias were assessed using semi-structured questionnaires. Findings indicated that exposure to fitness content on Instagram (β = 0.17, p < 0.001) and the pursuit of an ideal athletic body (β = 0.12, p = 0.034) were associated with increased weight bias. In contrast, engagement with body diversity content (β = -0.23, p < 0.001) and perceived pressure from media to conform to appearance ideals (β = -0.24, p < 0.001) had a mitigating effect on weight bias. Notably, body image perception did not mediate these relationships (p > 0.05). In conclusion, this study revealed a link between media exposure and weight bias among undergraduate nutrition students, independent of their body image perception. Developing social media literacy programs that encourage students to critically evaluate media content is imperative to reduce weight bias. Additionally, a deeper examination of the media content that contributes to weight bias and the potential need for targeted regulatory measures is warranted.
摘要:
这项研究调查了媒体和Instagram互动模式与巴西营养学家健康研究中本科营养学学生体重偏差之间的关系。我们还探讨了学生自身身体形象感知在这些关系中的潜在中介作用。共有406名学生(78%为女性)参加了这项横断面分析。社会人口统计数据,媒体影响力,Instagram互动模式,身体形象感知,和体重偏倚使用半结构化问卷进行评估。研究结果表明,暴露于Instagram上的健身内容(β=0.17,p<0.001)和对理想运动身体的追求(β=0.12,p=0.034)与体重偏差增加有关。相比之下,参与身体多样性含量(β=-0.23,p<0.001)和来自媒体的感知压力以符合外观理想(β=-0.24,p<0.001)对体重偏差有缓解作用。值得注意的是,身体形象感知并不调解这些关系(p>0.05)。总之,这项研究揭示了营养学本科生的媒体曝光与体重偏见之间的联系,独立于他们的身体形象感知。开发鼓励学生批判性地评估媒体内容的社交媒体素养计划对于减少体重偏见至关重要。此外,有必要对导致体重偏差的媒体内容进行更深入的检查,并可能需要采取针对性的监管措施。
