  1. Note. Change = Beta Coefficient. RR = Relative Risk. CI = Confidence Interval. Exposure Reference Category = Adults who did not misperceive their weight status. The multinomial logistic regression outcome reference group is sedentary adults; Total columns are gender-adjusted.
  2. a Multivariable regression models were adjusted for body mass index, age, education, income, marital status, self-reported health status, and receipt of medical diagnosis of overweight.
  3. b We also adjusted for physical activity in the total energy intake models.
  4. c Physical activity recommendations issued by the U.S. Department of Health and Human Services for 2008, defined as achieving greater than or equal to 150 minutes of moderate or 75 minutes of vigorous intensity physical activity per week, or a combination thereof. Those categorized as insufficiently active reported activity that did not exceed the above thresholds while those who did not report any physical activity were categorized as sedentary.
