: This study investigates the relationship between diet quality and body image disturbance among young women aged 18-24, a crucial period for establishing lifelong health behaviors. Given the increasing exposure to social media, which often promotes unrealistic beauty standards, this research aims to explore associations between eating behaviors, diet quality, and body image disturbance. : A mixed-methods approach was employed, combining qualitative focus group discussions with quantitative analysis. Focus groups ( = 19) explored themes of body image dissatisfaction. The Body Image Disturbance Questionnaire (BIDQ) was administered to 50 participants (young women aged 18-24) to quantitatively assess body image disturbance, while diet quality was evaluated using the Australian Recommended Food Scores (ARFS). The Three-Factor Eating Questionnaire (TFEQ-R18) was also used to assess eating behaviors, including cognitive restraint, uncontrolled eating, and emotional eating. A social influence questionnaire (SIQ) was administered to measure the effect of social influence. Pearson's correlation coefficient was used to determine the relationship between ARFS, BIDQ, and TFEQ-R18 scores. : Qualitative findings revealed persistent dissatisfaction with body shape, largely influenced by social media. Quantitatively, 65% of participants scored above the clinical threshold for body image disturbance (mean BIDQ score = 4.2, SD = 0.8). The correlation between ARFS and BIDQ scores was weak and not statistically significant (r = 0.057, = 0.711). However, a significant positive correlation was observed between time spent on social media and body image disturbance (r = 0.58, < 0.01). Additionally, TFEQ-R18 results indicated that 45% of participants displayed moderate levels of uncontrolled eating, and 36.5% demonstrated moderate levels of emotional eating. : While social media is associated with body image concerns, its effect on eating behaviors and diet quality shows weak correlations, suggesting that other factors may mediate these outcomes. These results suggest the complexity of the associations between body image, eating behaviors, and diet quality, indicating that interventions should consider psychological drivers behind these concerns alongside social media usage.
: 本研究调查了 18-24 岁年轻女性的饮食质量与身体意象障碍之间的关系，这是建立终身健康行为的关键时期。鉴于年轻人越来越多地接触社交媒体，这些媒体往往宣传不切实际的美丽标准，因此本研究旨在探讨饮食行为、饮食质量与身体意象障碍之间的关联。: 本研究采用混合方法，结合定性焦点小组讨论和定量分析。焦点小组（n=19）探讨了对身体不满的主题。身体意象障碍问卷（BIDQ）用于评估 50 名参与者（18-24 岁的年轻女性）的身体意象障碍程度，而饮食质量则使用澳大利亚推荐食物评分（ARFS）进行评估。还使用三因素饮食问卷（TFEQ-R18）评估饮食行为，包括认知控制、失控进食和情绪进食。社交影响问卷（SIQ）用于衡量社交影响的效果。采用皮尔逊相关系数确定 ARFS、BIDQ 和 TFEQ-R18 评分之间的关系。: 定性研究结果显示，年轻女性对身体形状的不满持续存在，主要受社交媒体影响。定量研究中，65%的参与者的身体意象障碍评分超过临床阈值（平均 BIDQ 得分为 4.2，标准差为 0.8）。ARFS 和 BIDQ 评分之间的相关性较弱且无统计学意义（r=0.057，p=0.711）。然而，社交媒体使用时间与身体意象障碍之间存在显著正相关（r=0.58，p<0.01）。此外，TFEQ-R18 结果表明，45%的参与者表现出中等程度的失控进食，36.5%表现出中等程度的情绪进食。: 虽然社交媒体与身体意象问题相关，但它对饮食行为和饮食质量的影响相关性较弱，这表明其他因素可能会影响这些结果。这些结果表明身体意象、饮食行为和饮食质量之间的关联很复杂，这表明干预措施应考虑这些问题背后的心理驱动因素以及社交媒体的使用。
