To examine temporal trends in sex and age specific incidence of self harm in children and adolescents, clinical management patterns, and risk of cause specific mortality following an index self harm episode at a young age. Population based cohort study. UK Clinical Practice Research Datalink-electronic health records from 647 general practices, with practice level deprivation measured ecologically using the index of multiple deprivation. Patients from eligible English practices were linked to hospital episode statistics (HES) and Office for National Statistics (ONS) mortality records. For the descriptive analytical phases we examined data pertaining to 16 912 patients aged 10-19 who harmed themselves during 2001-14. For analysis of cause specific mortality following self harm, 8638 patients eligible for HES and ONS linkage were matched by age, sex, and general practice with up to 20 unaffected children and adolescents (n=170 274). In the first phase, temporal trends in sex and age ...
Inception rates of deliberate self-harm among adolescents in West London
The International journal of social psychiatry, 2003
Studies have suggested that inception rates of deliberate self-harm among different ethnic group adolescents are broadly similar. We set out to study the rates of adolescent self-harm over a calendar year in Ealing--part of West London. All cases of deliberate self-harm presenting to the A&E department and paediatrics were identified and socio-cultural factors studied. Ethnicity was obtained using self-ascription. A total of 76 cases were identified over one year. Using the at risk population as denominator, no differences in inception rates were noted according to ethnicity. Overdoses were the commonest method used for deliberate self-harm. The similarities between the Asian and white adolescents suggest that some common aetiological factors may be at play. The risk factors may be related to gender rather than ethnicity in this age group.

Little is known about the relative incidence of fatal and non-fatal self-harm in young people. We estimated the incidence of suicide, hospital-presenting non-fatal self-harm, and community-occurring non-fatal self-harm in adolescents in England. We used national mortality statistics (Jan 1, 2011, to Dec 31, 2013), hospital monitoring data for five hospitals derived from the Multicentre Study of Self-Harm in England (Jan 1, 2011, to Dec 31, 2013), and data from a schools survey (2015) to estimate the incidence of fatal and non-fatal self-harm per 100 000 person-years in adolescents aged 12-17 years in England. We described these incidences in terms of an iceberg model of self-harm. During 2011-13, 171 adolescents aged 12-17 years died by suicide in England (119 [70%] male and 133 [78%] aged 15-17 years) and 1320 adolescents presented to the study hospitals following non-fatal self-harm (1028 [78%] female and 977 [74%] aged 15-17 years). In 2015, 322 (6%) of 5506 adolescents surveyed ...
Clinical and social outcomes of adolescent self harm: population based birth cohort study
BMJ (Clinical research ed.), 2014
To investigate the mental health, substance use, educational, and occupational outcomes of adolescents who self harm in a general population sample, and to examine whether these outcomes differ according to self reported suicidal intent. Population based birth cohort study. Avon Longitudinal Study of Parents and Children (ALSPAC), a UK birth cohort of children born in 1991-92. Data on lifetime history of self harm with and without suicidal intent were available for 4799 respondents who completed a detailed self harm questionnaire at age 16 years. Multiple imputation was used to account for missing data. Mental health problems (depression and anxiety disorder), assessed using the clinical interview schedule-revised at age 18 years, self reported substance use (alcohol, cannabis, cigarette smoking, and illicit drugs) at age 18 years, educational attainment at age 16 and 19 years, occupational outcomes at age 19 years, and self harm at age 21 years. Participants who self harmed with an...

To establish an estimate of prevalence in a nationally representative sample of community adolescents. To examine associations between self-harm and wellbeing. An anonymous self-report survey completed by 2000 adolescents aged 13-18 years across England. Wellbeing was measured using the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS). In total 15.5% (n = 309) of participants reported ever having self-harmed (95% confidence intervals 13.9-17.1). The median age of onset was 13.0 years. Females aged 13-15 years reported the highest incidence of self-harm within the past year (54.9%). Cutting elsewhere (other than on the arms) was more prevalent amongst females (56.4%). The mean wellbeing score for the whole sample (45.6) was lower than the WEMWBS validation score (48.8). Self-harm was associated with a significantly lower wellbeing score, with mean scores of 38.7 (ever self-harmed) and 46.8 (never self-harmed). Self-harm remains prevalent amongst adolescents aged 13-18 years in Engla...
