ABSTRACT
INTRODUCTION: Given the evidence that drinking patterns and self-harm hospital presentations have changed during COVID-19, this study aimed to examine any change in self-harm and suicide-related ideation presentations, together with any possible contribution made by alcohol or substance misuse, to Irish Emergency Departments in 2020, compared with 2018 and 2019. METHODS: A population-based cohort with self-harm and suicide-related ideation presenting to Irish hospitals derived from the National Clinical Programme for Self-Harm was analysed. Descriptive analyses were conducted based on sociodemographic variables and types of presentation for the period January to August 2020 and compared with the same period in 2018 and 2019. Binomial regression analyses were performed to investigate the independent effect of demographic characteristics and pre/during COVID-19 periods on the use of substances as contributory factors in the self-harm and suicide-related ideation presentations. RESULTS: 12,075 presentations due to self-harm and suicide-related ideation were recorded for the periods January-August 2018-2020 across nine emergency departments. The COVID-19 year was significantly associated with substances contributing to self-harm and suicide-related ideation ED presentations (OR = 1.183; 95% CI, 1.075-1.301, p < 0.001). No changes in the demographic characteristics were found for those with self-harm or suicide-related ideation across the years. Suicide-related ideation seemed to be increased after May 2020 compared with previous years. In terms of self-harm episodes with comorbid drug and alcohol overdose and poisoning, these were significantly increased in January-August 2020, compared with previous timepoints (χ2 = 42.424, df = 6, p < 0.001). CONCLUSION: An increase in suicide-related ideation and substance-related self-harm presentations may indicate longer term effects of the pandemic and its relevant restrictions. Future studies might explore whether those presenting with ideation will develop a risk of suicide in post-pandemic periods.
ABSTRACT
BACKGROUND: We aimed to estimate the prevalence of depressive symptoms as well as suicide-related ideation among Japanese university students during the stay-home order necessitated by the coronavirus disease 2019 pandemic in Japan, and offer evidence in support of future intervention to depression and suicide prevention strategies among college and university students. METHODS: The data for this cross-sectional study were derived from the Student Mental Health Survey conducted from May 20 to June 16, 2020 at a national university in Akita prefecture. Among the 5111 students recruited, 2712 participated in this study (response rate, 53%; mean age ± standard deviation, 20.5 ±3.5 years; men, 53.8%). Depressive symptoms were identified by using the Patient Health Questionnaire-9 (PHQ-9). RESULTS: The prevalence of moderate depressive symptoms based on a PHQ-9 score ≥10 and suicide-related ideation based on question 9 of PHQ-9 ≥1, which encompasses thoughts of both suicide and self-harm, was 11.7% and 6.7%, respectively. Multivariable logistic regression analyses showed that risk factors for depression included being a woman, smoking, alcohol consumption, and social network communication using either video or voice. For suicide-related ideation, alcohol consumption was the only risk factor. Exercise and having someone to consult about worries were associated with decreased risk of both depressive symptoms and suicide-related ideation. CONCLUSIONS: Negative lifestyles of smoking and drinking, and being a woman, may be important risk factors for depressive symptoms, whereas exercise and having someone to consult about worries may be protective factors.
