Aust N Z J Psychiatry 2022 48674221126649 ![]() OBJECTIVE: The aim of this study was to assess associations of various content areas of Twitter posts with help-seeking from the US National Suicide Prevention Lifeline (Lifeline) and with suicides. METHODS: We retrieved 7,150,610 suicide-related tweets geolocated to the United States and posted between 1 January 2016 and 31 December 2018. Using a specially devised machine-learning approach, we categorized posts into content about prevention, suicide awareness, personal suicidal ideation without coping, personal coping and recovery, suicide cases and other. We then applied seasonal autoregressive integrated moving average analyses to assess associations of tweet categories with daily calls to the US National Suicide Prevention Lifeline (Lifeline) and suicides on the same day. We hypothesized that coping-related and prevention-related tweets are associated with greater help-seeking and potentially fewer suicides. RESULTS: The percentage of posts per category was 15.4% (standard deviation: 7.6%) for awareness, 13.8% (standard deviation: 9.4%) for prevention, 12.3% (standard deviation: 9.1%) for suicide cases, 2.4% (standard deviation: 2.1%) for suicidal ideation without coping and 0.8% (standard deviation: 1.7%) for coping posts. Tweets about prevention were positively associated with Lifeline calls (B=1.94, SE=0.73, p=0.008) and negatively associated with suicides (B=-0.11, standard error=0.05, p=0.038). Total number of tweets were negatively associated with calls (B=-0.01, standard error =0.0003, p=0.007) and positively associated with suicide, (B=6.410(-5), standard error =2.610(-5), p=0.015). CONCLUSION: This is the first large-scale study to suggest that daily volume of specific suicide-prevention-related social media content on Twitter corresponds to higher daily levels of help-seeking behaviour and lower daily number of suicide deaths.

Association of Logic's hip hop song "1-800-273-8255" with Lifeline calls and suicides in the United States: interrupted time series analysis
Niederkrotenthaler T , Tran US , Gould M , Sinyor M , Sumner S , Strauss MJ , Voracek M , Till B , Murphy S , Gonzalez F , Spittal MJ , Draper J . BMJ 2021 375 e067726 OBJECTIVE: To assess changes in daily call volumes to the US National Suicide Prevention Lifeline and in suicides during periods of wide scale public attention to the song "1-800-273-8255" by American hip hop artist Logic. DESIGN: Time series analysis. SETTING: United States, 1 January 2010 to 31 December 2018. PARTICIPANTS: Total US population. Lifeline calls and suicide data were obtained from Lifeline and the Centers for Disease Control and Prevention. MAIN OUTCOME MEASURES: Daily Lifeline calls and suicide data before and after the release of the song. Twitter posts were used to estimate the amount and duration of attention the song received. Seasonal autoregressive integrated moving average time series models were fitted to the pre-release period to estimate Lifeline calls and suicides. Models were fitted to the full time series with dummy variables for periods of strong attention to the song. RESULTS: In the 34 day period after the three events with the strongest public attention (the song's release, the MTV Video Music Awards 2017, and Grammy Awards 2018), Lifeline received an excess of 9915 calls (95% confidence interval 6594 to 13 236), an increase of 6.9% (95% confidence interval 4.6% to 9.2%, P<0.001) over the expected number. A corresponding model for suicides indicated a reduction over the same period of 245 suicides (95% confidence interval 36 to 453) or 5.5% (95% confidence interval 0.8% to 10.1%, P=0.02) below the expected number of suicides. CONCLUSIONS: Logic's song "1-800-273-8255" was associated with a large increase in calls to Lifeline. A reduction in suicides was observed in the periods with the most social media discourse about the song. |
Characteristics of U.S. suicide decedents in 2005-2010 who had received mental health treatment
Niederkrotenthaler T , Logan JE , Karch DL , Crosby A . Psychiatr Serv 2014 65 (3) 387-90 OBJECTIVE: To inform suicide prevention efforts in mental health treatment, the study assessed associations between recent mental health treatment, personal characteristics, and circumstances of suicide among suicide decedents. METHODS: Data from 18 states reporting to the National Violent Death Reporting System between 2005 and 2010 (N=57,877 suicides) were used to compare circumstances among adult decedents receiving any or no type of mental health treatment within two months before death. RESULTS: Of suicide decedents, 28.5% received treatment before suicide. Several variables were associated with higher odds of receiving treatment, including death by poisoning with commonly prescribed substances (adjusted odds ratio [AOR]=3.04, 95% confidence interval [CI]=2.84-3.26), a history of suicide attempts (AOR=2.77, CI=2.64-2.90), depressed mood (AOR=1.69, CI=1.62-1.76), and nonalcoholic substance abuse or dependence (AOR=1.13, CI=1.07-1.19). CONCLUSIONS: For nearly a third of all suicide decedents, better mental health care might have prevented death. Efforts to reduce access to lethal doses of prescription medications seem warranted to prevent overdosing with commonly prescribed substances. |
Injuries and post-traumatic stress following historic tornados: Alabama, April 2011
Niederkrotenthaler T , Parker EM , Ovalle F , Noe RE , Bell J , Xu L , Morrison MA , Mertzlufft CE , Sugerman DE . PLoS One 2013 8 (12) e83038 OBJECTIVES: We analyzed tornado-related injuries seen at hospitals and risk factors for tornado injury, and screened for post-traumatic stress following a statewide tornado-emergency in Alabama in April 2011. METHODS: We conducted a chart abstraction of 1,398 patients at 39 hospitals, mapped injured cases, and conducted a case-control telephone survey of 98 injured cases along with 200 uninjured controls. RESULTS: Most (n = 1,111, 79.5%) injuries treated were non-life threatening (Injury Severity Score ≤15). Severe injuries often affected head (72.9%) and chest regions (86.4%). Mobile home residents showed the highest odds of injury (OR, 6.98; 95% CI: 2.10-23.20). No severe injuries occurred in tornado shelters. Within permanent homes, the odds of injury were decreased for basements (OR, 0.13; 95% CI: 0.04-0.40), bathrooms (OR, 0.22; 95% CI: 0.06-0.78), hallways (OR, 0.31; 95% CI: 0.11-0.90) and closets (OR, 0.25; 95% CI: 0.07-0.80). Exposure to warnings via the Internet (aOR, 0.20; 95% CI: 0.09-0.49), television (aOR, 0.45; 95% CI: 0.24-0.83), and sirens (aOR, 0.50; 95% CI: 0.30-0.85) decreased the odds of injury, and residents frequently exposed to tornado sirens had lower odds of injury. The prevalence of PTSD in respondents was 22.1% and screening positive for PTSD symptoms was associated with tornado-related loss events. CONCLUSIONS: Primary prevention, particularly improved shelter access, and media warnings, seem essential to prevent severe tornado-injury. Small rooms such as bathrooms may provide some protection within permanent homes when no underground shelter is available. |
Descriptive factors of abusive head trauma in young children-United States, 2000-2009
Niederkrotenthaler T , Xu L , Parks SE , Sugerman DE . Child Abuse Negl 2013 37 (7) 446-55 OBJECTIVE: Abusive head trauma (AHT) is a leading cause of severe injury in maltreated children in the United States. There is little research from nationally representative datasets available to characterize young children who had AHT compared to non-abusive head trauma (NAHT). METHODS: Using the recent CDC AHT case definition, we performed a retrospective analysis of 2000, 2003, 2006 and 2009 hospitalization data using the Kids' Inpatient Database (KID) from the Healthcare Cost and Utilization Project. Logistic regression was used to compare AHT to NAHT patients <2 years of age. Socio-demographic data and indicators of socioeconomic status (i.e., insurance status and household income), presence of chronic conditions, injury severity (i.e., length of hospital stay and vital status), hospital specialization (i.e., hospital type), hospital region, and season of admission were used as independent variables. RESULTS: A weighted sample of 7,603 AHT and 25,339 NAHT patients was identified. National rates for AHT were 39.8 per 100,000 population for children <1 year and 6.8 per 100,000 population for children 1 year old. Compared to NAHT, children with AHT were more often <1 year of age (adjusted odds ratio [aOR]=2.66; 95% confidence interval [CI]: 2.35-3.01), male (aOR=1.10; 95% CI: 1.01-1.20), enrolled in Medicaid (aOR=2.78; 95% CI: 2.49-3.11), hospitalized longer (aOR=8.26; 95% CI: 7.24-9.43), died during hospitalization (aOR=5.12; 95% CI: 4.01-6.53), and seen at children's hospitals (aOR=1.97; 95% CI: 1.63-2.38) and hospitals outside the Northeast [aOR=2.65 (95% CI: 2.10-3.33) for the Midwest, 1.90 (95% CI: 1.52-2.38) for the South and 1.93 (95% CI: 1.45-2.57) for the West, respectively]. CONCLUSIONS: The results confirm that injuries from AHT are more severe and more often lethal than other head injuries. Socioeconomically disadvantaged families with children <1 year are an important focus for primary prevention. The associations of AHT, compared to NAHT with hospital type and hospital region warrant further investigation. Referral or reporting patterns, or true differences in the incidence may contribute to the identified associations. |
