Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not a proven foodborne pathogen, the COVID-19 pandemic has put the food system on alert, and food safety has been identified as an important pillar in mitigating the crisis. Therefore, an understanding of how popular media are used as a vital disseminator of food safety and health information for the public is more important than ever. YouTube deserves particular attention as one of the most highly trafficked Web sites on the Internet, especially because YouTube has been blamed during the pandemic for spreading misleading or untrustworthy information that contradicts validated information. This study was conducted to evaluate the food safety information and practices circulating on YouTube during the COVID-19 pandemic and the alignment of these practices with recommendations from government agencies. A search for videos on YouTube was conducted using the key words “food and COVID-19,” “food safety and COVID-19,” and “groceries and COVID-19.” After applying a series of inclusive and exclusive criteria, 85 videos from the United States and Canada were evaluated. More than half (69%) of the videos presented hand washing procedures, 26% showed kitchen disinfection, and most (86%) showed take-out food or grocery store practices. Multiple produce washing procedures were also shown throughout videos. Food was not considered hazardous in 39% of the videos, but 24% mentioned that food packaging is potentially hazardous. Most videos cited government agencies and had a host or guest who was a health care professional, professor, or expert. Three videos were not aligned with a government agency's guideline or information cited; two were presented by a health care professional. These findings reveal the need to develop educational interventions that increase YouTube video host and guest awareness of social media use as a tool for food safety dissemination and the need to provide trustworthy information.

investment rather than by the private sector alone, or through public-private partnerships.Many LMIC have included school-based interventions in their nutrition policies to combat the burdens of unhealthy diets. Recent systematic reviews of policy actions to improve diets in LMIC indicated that school-based activities are present in several different regions (Lachat et al., 2013;Darfour-Oduro et al., 2019). Schools are an attractive entry point to improve children's diets, as their eating habits can be shaped during childhood and the information disseminated from school can reach adults through children (

BACKGROUND Cigarette smoking is a leading cause of preventable death, and identifying novel treatment approaches to promote smoking cessation is critical for improving public health. With the rise of digital health and mobile apps, these tools offer potential opportunities to address smoking cessation, yet the functionality of these apps and whether they offer scientifically based support for smoking cessation are unknown. OBJECTIVE The goal of this research was to use the American Psychiatric Association app evaluation model to evaluate the top-returned apps from Android and Apple app store platforms related to smoking cessation and investigate the common app features available for end users. METHODS We conducted a search of both Android and iOS app stores in July 2021 for apps related to the keywords “smoking,” “tobacco,” “smoke,” and “cigarette” to evaluate apps for smoking cessation. Apps were screened for relevance, and trained raters identified and analyzed features, including accessibility (ie, cost), privacy, clinical foundation, and features of the apps, using a systematic framework of 105 objective questions from the American Psychiatric Association app evaluation model. All app rating data were deposited in mindapps, a publicly accessible database that is continuously updated every 6 months given the dynamic nature of apps available in the marketplace. We characterized apps available in July 2021 and November 2022. RESULTS We initially identified 389 apps, excluded 161 due to irrelevance and nonfunctioning, and rated 228, including 152 available for Android platforms and 120 available for iOS platforms. Some of the top-returned apps (71/228, 31%) in 2021 were no longer functioning in 2022. Our analysis of rated apps revealed limitations in accessibility and features. While most apps (179/228, 78%) were free to download, over half had costs associated with in-app purchases or full use. Less than 65% (149/228) had a privacy policy addressing the data collected in the app. In terms of intervention features, more than 56% (128/228) of apps allowed the user to set and check in on goals, and more than 46% (106/228) of them provided psychoeducation, although few apps provided evidence-based support for smoking cessation, such as peer support or skill training, including mindfulness and deep breathing, and even fewer provided evidence-based interventions, such as acceptance and commitment therapy or cognitive behavioral therapy. Only 12 apps in 2021 and 11 in 2022 had published studies supporting the feasibility or efficacy for smoking cessation. CONCLUSIONS Numerous smoking cessation apps were identified, but analysis revealed limitations, including high rates of irrelevant and nonfunctioning apps, high rates of turnover, and few apps providing evidence-based support for smoking cessation. Thus, it may be challenging for consumers to identify relevant, evidence-based apps to support smoking cessation in the app store, and a comprehensive evaluation system of mental health apps is critically important.
