Posting edited selfies on social media may make you more at risk for an eating disorder, a new study says

A recent study, published in the International Journal of Eating Disorders, found a "consistent and direct link" between posting edited photos on Instagram and eating disorder risk factors.

(CNN)Turns out, all those selfies we've edited and posted on social media could be more problematic than we thought.

A recent study, published in the International Journal of Eating Disorders, found a "consistent and direct link" between posting edited photos on Instagram and eating disorder risk factors -- such as concerns over a person's weight and shape, as well as urges to exercise and to restrict food intake.
The study's release comes amid the coronavirus pandemic, which has left many people suffering with eating disorders facing new challenges. Support groups estimate that as many as 30 million people in the US are living with an eating disorder.
"Although people may think it's harmless to post edited photos to Instagram, we found this increases eating disorder risk," Pamela Keel, a professor at Florida State University and co-author of the study, told CNN.
"It's important for people to know how to use social media safely as they turn more to these platforms to stay connected during this pandemic."

'That activity was not okay'

Keel and her team of researchers at the university, who released the study's findings on Wednesday, surveyed 2,485 undergraduate students (76% female), asking whether they use editing apps that go beyond Instagram's filters in altering a person's appearance before they post.
Students also answered questions related to their attitudes about eating, their anxiety levels, and depression symptoms.
About 26.6% of the respondents -- one in three women, and one in 14 men -- said that they were editing photos before uploading them to their Instagram accounts, according to the study.
The study found higher levels of anxiety and eating pathology for respondents who said they post edited photos to Instagram. People who said they posted edited photos were almost twice as likely to score above the threshold for a probable eating disorder than those who didn't, Keel said.
However, that's not what the study's authors found most shocking. Previous research has already pointed to links between using social media and increased body dissatisfaction.
So Keel and her team decided to take their research further by conducting an experiment specifically looking at whether the actual act of posting edited photos increases the risk factors for eating disorders.
In the experiment, 80 students -- among those who said they use editing apps -- had their photos taken by the researchers over a neutral background.
Students were asked to look at the photo of themselves for one minute, then they completed a questionnaire to establish their baseline levels around variables associated with disordered eating, anxiety and depression.
After that, they were randomly assigned to one of four possible tasks: editing and posting the picture, posting the picture without editing it, editing the picture without posting it, or neither editing nor posting the picture. They then answered more questions, which allowed the researchers to note any changes in their perceptions from the baseline they established initially.
Researchers discovered that posting a picture, edited or not, caused people to feel more concerned about their weight and shape. They also saw that the combination of editing and posting the photo was associated with an even more significant increase in those concerns.
"That's important," Keel said, "because those weight and shape concerns are the most potent risk factor for the development of an eating disorder. So we were able to see that in real time that that's just, that activity was not okay."

How editing and posting photos can impact your mental health

The practice of editing photos often forces people to identify something wrong with their appearance, according to Keel.
"You have to first go through the process of saying: what's wrong with what I look like? What do I fix?"
Putting a photo out there for others to look at, right after going through this mental inventory of flaws "might not feel very reassuring," Keel added.
