Objective. To assess caloric knowledge of participants and determine if an e-mail and/or text message intervention could increase knowledge of recommended daily caloric intake. Design. Randomized, control trial. Setting. Johns Hopkins Hospital Cobblestone Café. Participants. The 246 participants reported eating at the Café at least twice/week. Intervention(s). Participants randomized to control, e-mail, or text condition. The text and e-mail conditions received a message on four consecutive Mondays stating the recommended daily caloric intake. Main outcome measures. Knowledge of the government reference value of 2,000 calories. Analysis. Intention-to-treat analysis was conducted. Multivariate logistic regression examined the effectiveness of text and e-mail messaging for improving knowledge of the government calorie reference value. Results. Baseline awareness of the daily calorie reference value in study population was low. Participants in the text message condition were twice as likely to know the government calorie reference value compared to controls (p = .047, odds ratio = 2.2, 95% confidence interval [1.01, 4.73]). No significant differences were found for the e-mail condition (p = .5). Conclusions and implications. Many people do not know the daily recommended caloric intake. Public education on the government calorie reference value is necessary for menu-labeling interventions to be more effective. Weekly text messaging can serve as an effective modality for delivering calorie information and nutrition education.
This research output has an Altmetric Attention Score of 66. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 August 2019.
All research outputs
#712,352
of 27,653,074 outputs
Outputs from Health Promotion Practice
#25
of 1,658 outputs
Outputs of similar age
#6,191
of 242,453 outputs
Outputs of similar age from Health Promotion Practice
#2
of 15 outputs
Altmetric has tracked 27,653,074 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 97th percentile: it's in the top 5% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,658 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.6. This one has done particularly well, scoring higher than 98% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 242,453 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 97% of its contemporaries.
We're also able to compare this research output to 15 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 86% of its contemporaries.
