Social media use, eating attitudes, orthorexia nervosa and well-being: testing a moderated mediation model.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeCurrently, there is a growing awareness among individuals about health and nutrition. Therefore, it is important to comprehend the factors that influence eating habits and attitudes. This study aims to investigate the potential mediation effect of eating attitudes in the relationship between social media use and well-being, as well as to explore whether the moderating effect of the level of orthorexia nervosa influences this relationship.
methodsThe sample consisted of 599 adults (M
resultsThe study found that eating attitudes played a partial mediating role in the relationship between social media use and well-being among adults. Social media use positively predicted eating attitudes (β = .83, p < .001) and well-being (β = 1.05, p < .05), and eating attitudes significantly predicted well-being (β = .94, p < .001). Also, orthorexia nervosa moderated the mediating effect of eating attitudes in the relationship between social media use and well-being. Interestingly, the moderating effect was stronger among individuals with low levels of orthorexia nervosa, contrary to initial expectations.
conclusionsThe current study suggests that eating attitudes are a key behavioral mechanism linking social media use and well-being, and this pathway is influenced by individuals' orthorexia nervosa tendencies. These findings could aid in the development of interventions for eating disorders at both clinical and social levels and guide individuals towards healthier lifestyles. Importantly, while orthorexia nervosa moderated the indirect relationship between social media use and well-being, the study did not find a direct association between orthorexia nervosa and social media use. LEVEL OF EVIDENCE: Level III. Evidence obtained from well-designed cohort or case-control analytic studies.
