Of these tweets, 2,161,357 (51.3%) were related to “depression,” whereas 1,923,635 (45.66%), 225,205 (5.35%), and 150,006 (3.56%) were related to “anxiety,” “insomnia,” and “addiction,” respectively. Compared to the general public, health care workers had higher risks of all 4 types of problems (all P<.001), and they were more concerned about clinical topics than everyday issues (eg, “students’ pressure,” “panic buying,” and “fuel problems”) than the general public. Finally, the lockdown policy had significant associations with public mental health in 4 out of the 12 states we studied, among which Pennsylvania showed a positive association, whereas Michigan, North Carolina, and Ohio showed the opposite (all P<.05). Conclusions: The impact of COVID-19 and the corresponding control measures on the public’s mental status is dynamic and shows variability among different cohorts regarding disease types, occupations, and regional groups. Health agencies and policy makers should primarily focus on depression (reported by 51.3% of the tweets) and insomnia (which has had an ever-increasing trend since the beginning of the pandemic), especially among health care workers. Our pipeline timely tracks and analyzes public mental health changes, especially when primary studies and large-scale surveys are difficult to conduct. %M 36191167 %R 10.2196/39676 %U //www.mybigtv.com/2022/10/e39676 %U https://doi.org/10.2196/39676 %U http://www.ncbi.nlm.nih.gov/pubmed/36191167
