en Suicide and Self-Harm مروری Review Article <span style="font-size:12px;"><span style="font-family:Tahoma;"><span style="background:white"><span style="line-height:150%"><span style="color:black">Suicide, as a serious public health challenge, not only imposes a heavy psychosocial burden on families and society, but also, given its upward trend in certain regions of the country, necessitates the development of precise registration and monitoring systems. A study focusing on the design and implementation of a qualitative registry system for suicide attempts in Hamadan Province, Iran, demonstrates that such a system can provide a clear picture of the demographic patterns, risk factors, prevalent methods, and outcomes of suicide. The findings of this research, based on continuous and prospective registration over one year, indicate the predominance of familial (e.g., conflicts with family members, marital problems) and interpersonal factors, a high prevalence of drug ingestion as the primary method, and a concentration of harm within younger age groups and the urban population. Complementary analyses utilizing machine learning methods have demonstrated that variables, such as age, gender, education level, marital status, and method of attempt, are the strongest predictors of suicide outcomes. This policy brief, while critiquing the current national registration and reporting system, emphasizes the necessity of strengthening registration infrastructure, training human resources, and utilizing registered data for designing targeted interventions, and provides operational recommendations for health policymakers.</span></span></span></span></span><br> &nbsp; Suicide, Registry System, Prevention, Health Policy, Hamadan 0 0 http://ajnpp.umsha.ac.ir/browse.php?a_code=A-10-30-1&slc_lang=en&sid=1 Ali Ghaleiha علی ghaleiha@umsha.ac.ir 10031947532846009257 10031947532846009257 No Behavioral Disorders and Substance Abuse Research Center, Institute of Neuroscience and Mental Health, Hamadan University of Medical Sciences, Hamadan, Iran Behnaz Alafchi بهناز b.alaafchi@umsha.ac.ir 10031947532846009258 10031947532846009258 No Modeling of Noncommunicable Diseases Research Center, Hamadan University of Medical Sciences, Hamadan, Iran Zahra Taslimi زهرا تسلیمی za_t520@ymail.com 10031947532846009259 10031947532846009259 No Behavioral Disorders and Substance Abuse Research Center, Institute of Neuroscience and Mental Health, Hamadan University of Medical Sciences, Hamadan, Iran Salman Khazaei سلمان خزایی s.khazaei@umsha.ac.ir 10031947532846009260 10031947532846009260 No Health Research Center, Institute of Health Sciences and Technology, Hamadan University of Medical Sciences, Hamadan, Iran Erfan Ayubi عرفان ایوبی e.aubi@umsha.ac.ir 10031947532846009261 10031947532846009261 No Social Determinants of Health Research Center, Institute of Health Sciences and Technology, Hamadan University of Medical Sciences, Hamadan, Iran Nasrin Matinnia نسرین متین نیا nmatinnia@yahoo.com 10031947532846009262 10031947532846009262 No Department of Nursing, Islamic Azad University, Ha.C., Hamedan, Iran Saeid Yazdi-Ravandi سعید یزدی راوندی Yazdiravandi@umsha.ac.ir 10031947532846009263 10031947532846009263 Yes Behavioral Disorders and Substance Abuse Research Center, Institute of Neuroscience and Mental Health, Hamadan University of Medical Sciences, Hamadan, Iran
