The COVID-19 (SARS-CoV-2) pandemic has jeopardized humanity worldwide and has considerably altered the healthy lifestyle behaviors of societies. This study examined the possible mediating role of sleep quality in the relationship between orthorexia nervosa and fear of COVID-19 among Turkish adults. This study used an observational and descriptive design. It was carried out online with 1,130 participants across Turkey between April and August 2021. The data were collected using a questionnaire, the Fear of COVID-19 Scale (FC-19S), the Pittsburgh Sleep Quality Index (PSQI), and Orthorexia Nervosa-R (ON-R). The participants had an ON-R mean score of 3.08 ± 0.90 and a mean PSQI score of 8.03 ± 2.80. Likewise, their mean FC-19S score was 18.24 ± 6.55. There was a significant positive correlation between the FC-19S and the PSQI (r = 0.208; p = 0.000) as well as a significant negative correlation between the ON-R and the PSQI (r = - 0.145; p = 0.000). In addition, the results of the process model analysis supported our hypotheses that the PSQI was a predictor of ON-R and that its direct and indirect effects were moderated by FC19S and the PSQI. A one-unit increase in FC-19S scores causes an average 1% increase on the ON-R scale, while it generates an 8% increase on the PSQI. It was determined that the PSQI total score caused an average of 6% increase in the ON-R scale score. The findings of this study showed that sleep quality has a mediating role in the relationship between orthorexia nervosa and fear of COVID-19 experienced by Turkish adults during the pandemic. For this reason, governments need to take the necessary precautions concerning this subject when creating action plans for possible global crisis situations that may adversely affect public health in the future.
新型冠状病毒肺炎（SARS-CoV-2）大流行给全世界的人类带来了威胁，并极大地改变了社会的健康生活方式行为。本研究调查了睡眠质量在土耳其成年人的神经性厌食症与对新型冠状病毒肺炎恐惧之间的关系中可能起到的中介作用。本研究采用观察性和描述性设计。于 2021 年 4 月至 8 月期间，在土耳其通过在线方式对 1130 名参与者进行了研究。使用问卷、新型冠状病毒肺炎恐惧量表（FC-19S）、匹兹堡睡眠质量指数（PSQI）和神经性厌食症量表（ON-R）收集数据。参与者的 ON-R 平均得分为 3.08±0.90，PSQI 平均得分为 8.03±2.80。同样，他们的 FC-19S 平均得分为 18.24±6.55。FC-19S 与 PSQI 之间呈显著正相关（r=0.208；p=0.000），ON-R 与 PSQI 之间呈显著负相关（r=-0.145；p=0.000）。此外，过程模型分析的结果支持我们的假设，即 PSQI 是 ON-R 的预测因子，其直接和间接效应受到 FC19S 和 PSQI 的调节。FC-19S 分数增加一个单位，ON-R 量表的分数平均增加 1%，而 PSQI 的分数增加 8%。PSQI 总分导致 ON-R 量表得分平均增加 6%。本研究的结果表明，在大流行期间，睡眠质量在土耳其成年人的神经性厌食症与对新型冠状病毒肺炎恐惧之间的关系中起中介作用。因此，政府在制定可能对未来公共健康产生不利影响的全球危机情况行动计划时，需要对此主题采取必要的预防措施。
