Adjusted odds ratio (aOR) and 95% CI of health information sharing and social media information use by social media health misinformation perceptions^a.

Social media misinformation perception	Sharing personal health informationb (n=4136), aOR (95% CI)	Sharing general health informationc (n=4159), aOR (95% CI)	Using social media information to make health decisionsd (n=4177), aOR (95% CI)	Using social media information in discussions with health care providerse (n=4174), aOR (95% CI)
High perceived misinformation amountf	0.803 (0.591-1.092)	0.742 (0.568-0.968)g	0.273 (0.156-0.479)	0.460 (0.323-0.655)

^aAnalyses were adjusted for age, sex, educational level, race or ethnicity, income, geographic residence, health literacy, digital literacy, and numeracy.

^bThe probability modeled was odds of having ever shared personal information on social media (shared almost every day, at least once a week, a few times a month, or less than once a month in the past 12 months) in reference to having never shared.

^cThe probability modeled was odds of having ever shared general information on social media (shared almost every day, at least once a week, a few times a month, or less than once a month in the past 12 months) in reference to having never shared.

^dThe probability modeled was odds of using social media information for making health decisions (strongly agree or somewhat agree) in reference to not using social media information for making health decisions (strongly disagree or somewhat disagree).

^eThe probability modeled was odds of using social media information in discussions with health care providers (strongly agree or somewhat agree) in reference to not using social media information in discussions with health care providers (strongly disagree or somewhat disagree).

^fHigh perceived misinformation amount=thinking that a lot of the health information on social media is false or misleading; low perceived misinformation amount=thinking that none, a little, or some of the health information on social media is false or misleading.

^gItalicized values are statistically significant (P<.05).

^hHigh perceived discernment difficulty=strongly or somewhat agreeing that it is hard to tell whether health information on social media is true or false; low perceived discernment difficulty=strongly or somewhat disagreeing that it is hard to tell whether health information on social media is true or false.
