| Outline of Final Research Achievements |
First, I assess whether the number of tweets on Twitter changes during suicide prevention periods. The number of preventive tweets increased by 15.62 tweets (95% CI 4.16, 27.09 p=0.008) during suicide support periods.
Next, I analysed to identify factors underlying individuals' vulnerability to suicide based on recent increases in suicide-related tweets. Results were following. Individuals aged 40 years or younger, there was significantly high effect modifications (OR=1.09, 95% CI 1.03-1.15 compared with older individuals). Additionally, males (OR=1.12, 95% CI 1.07-1.18), those who were unemployed (RRR=1.12, 95% CI 1.02-1.22), those who were divorced (RRR=1.11, 95% CI 1.03-1.19), and residents of urban areas (OR=1.26, 95% CI 1.17-1.35) had significantly high effect modifications.
