Bottom Line: There has been a marked rise in suicide by charcoal burning (CB) in some East Asian countries but little is known about its incidence in mainland China.Two-thirds of the web links retrieved using the search engine contained detailed information about the CB suicide method, of which 15% showed pro-suicide attitudes, and the majority (86%) did not encourage people to seek help.Better surveillance and intervention strategies need to be developed and implemented.

ABSTRACT

Background: There has been a marked rise in suicide by charcoal burning (CB) in some East Asian countries but little is known about its incidence in mainland China. We examined media-reported CB suicides and the availability of online information about the method in mainland China.

Methods: We extracted and analyzed data for i) the characteristics and trends of fatal and nonfatal CB suicides reported by mainland Chinese newspapers (1998-2014); ii) trends and geographic variations in online searches using keywords relating to CB suicide (2011-2014); and iii) the content of Internet search results.

Results: 109 CB suicide attempts (89 fatal and 20 nonfatal) were reported by newspapers in 13 out of the 31 provinces or provincial-level-municipalities in mainland China. There were increasing trends in the incidence of reported CB suicides and in online searches using CB-related keywords. The province-level search intensities were correlated with CB suicide rates (Spearman's correlation coefficient = 0.43 [95% confidence interval: 0.08-0.68]). Two-thirds of the web links retrieved using the search engine contained detailed information about the CB suicide method, of which 15% showed pro-suicide attitudes, and the majority (86%) did not encourage people to seek help.

Limitations: The incidence of CB suicide was based on newspaper reports and likely to be underestimated.

Conclusions: Mental health and suicide prevention professionals in mainland China should be alert to the increased use of this highly lethal suicide method. Better surveillance and intervention strategies need to be developed and implemented.

pone.0140686.g001: Trends in newspaper reports of fatal and nonfatal charcoal burning suicides.

Mentions: Time trend analysis indicated an increase in CB cases reported in the newspapers, whether only fatal or both fatal and nonfatal cases were included (see Fig 1a and 1b). The coefficient of the simple linear regression of fatal cases was 0.0000939 (p<0.001) with 21 peaks (Fig 1a), whereas that of fatal and nonfatal cases was 0.0001164 (p<0.001) with 24 peaks (Fig 1b). After excluding major influential values, the increasing trends became 0.0000325 and 0.0000373 respectively, but remained statistically significant (p<0.001).
