Deliberate self‐harm in adolescents: a study of characteristics and trends in Oxford, 1990–2000

Abstract

Clinical management of DSH in adolescents requires a range of responses, often involving multiservice and multidisciplinary input. Preventive initiatives in schools are also required.

Psychological characteristics, stressful life events and deliberate self-harm: findings from the Child & Adolescent Self-harm in Europe (CASE) Study

“…Self-harm shows strong links with stress factors (Hawton and Harriss, 2008), including difficulties in familial relationships (Byrne et al, 2008, Hawton et al, 2003, McDonald et al, 2007, poor relationships with friends and partners (Dimmock et al, 2008, Hawton et al, 2003 and perceptions of poor academic performance (Martin et al, 2005).…”

Differing patterns in intentional and unintentional poisonings among young people in England, 1998–2014: a population-based cohort study

“…[17] Adolescent poisoning rates are higher in females than males. [11,[18][19][20] Poisonings among 10-14 year olds in the US were shown to reduce from 1993-95 to 2000-04, [7] but increase in the UK among 15-19 year olds from 1987/8 to 1992/3 [6] and 10-17 year olds between 1992 and 2012. [5] The existing literature examining this temporal relationship is, however, either out of date and based on single data sources [6][7][8] or likely to have significantly underestimated incidence.…”

“…On the basis of existing evidence and theoretical plausibility, interactions between sex and age, [11] time period and sex, [11] time and age [16] plus time and socio-economic deprivation were assessed using LRTs comparing models with and without interaction terms (p<0.01), with stratified incidence rates presented where interactions were significant. Data were analysed using StataSE version 12.…”

“…[5] The existing literature examining this temporal relationship is, however, either out of date and based on single data sources [6][7][8] or likely to have significantly underestimated incidence. [5] Indeed most adolescent poisoning epidemiology studies to date have examined data from single hospitals or emergency departments [6,7,11,12,[21][22][23][24][25] with few using national hospitalisation, [8,16,17] poison centre, [26] or large primary care datasets including data on primary and secondary care service use. [5,9] What this study adds This is one of the largest population-based studies to date examining adolescent poisoning epidemiology, while CPRD is broadly representative of the demographics of the UK population.…”

“…[5] As primary care records are likely to underestimate self-harm events by up to 30%, [10] this study uses a large primary care dataset linked to hospitalisation and mortality data. Given that self-harm incidence may increase beyond age 17 into early adulthood, [11,12] we also present analyses covering a wider age range, using more contemporaneous data, reporting variations in poisoning incidence by age, sex, intent, deprivation and time-trends that would be useful for informing planning and delivery of poison prevention and treatment services.…”
