Suicide attempts by self-poisoning have become a critical health problem. This study aimed to investigate the trend, incidence, and the associated risk factors of suicide attempts by self-poisoning. A total of 7398 Egyptian patients were analyzed. The trend of suicide attempts by self-poisoning was analyzed using 6745 patients over four registry years from January 1, 2016, to January 1, 2020. Then, the associated risk factors behind attempted suicide by self-poisoning from January 1, 2019, to January 1, 2020, were assessed using 2523 suicide attempters by self-poisoning, 201 fatalities by self-poisoning, and another 653 survivors of accidental poisoning. Results showed a rising trend of suicide attempts by self-poisoning over the studied years. The incidence of suicide attempts through deliberate self-poisoning represented 26.63/1,000 (CI95%: 25.63-27.86) to the admitted patients and 26.10/100,000 (CI95%: 25.10-27.14) to the regional population. The death rate due to suicide attempts by self-poisoning was 2.08/100,000 (1.90-2.49). The case fatality rate and the proportionate mortality rate for suicide by self-poisoning were 7.38% (CI95%: 6.45-8.42) and 14.11% (CI95%: 12.4-16.0) respectively. Multivariate analysis revealed that attempted suicide by self-poisoning was predicted among patients aged <25 or 25-40 years old (OR = 27.49, CI95%: 15.28-49.64 and OR = 59.42, CI95%: 32.76-107.77 respectively), those of low or moderate socioeconomic status (OR = 35.03, CI95%: 21.32-57.56 and OR = 14.11, CI95%: 10.86-18.43 respectively), students (OR = 2.91, CI95%: 1.57-5.43) and those living in rural residency (OR = 4.12, CI95%: 3.27-5.19). Suicide attempts by self-poisoning exhibited an incremental rise across time which raises a serious concern. Efforts should be directed to overcome the mentioned risk factors triggering suicide attempts by self-poisoning.
自杀未遂已成为一个严重的健康问题。本研究旨在调查自杀未遂的趋势、发生率和相关的危险因素。分析了 7398 名埃及患者。通过对 2016 年 1 月 1 日至 2020 年 1 月 1 日四年期间登记的 6745 名患者，分析了自杀未遂的趋势。然后，通过对 2019 年 1 月 1 日至 2020 年 1 月 1 日期间的 2523 名自杀未遂者、201 名自杀死亡者和另外 653 名意外中毒幸存者进行评估，评估了自杀未遂背后的相关危险因素。结果显示，在研究期间，自杀未遂呈上升趋势。蓄意自杀的发生率代表了入院患者中的 26.63/1000（95%CI95%：25.63-27.86）和区域人群中的 26.10/100,000（95%CI95%：25.10-27.14）。自杀未遂的死亡率为 2.08/100,000（1.90-2.49）。自杀未遂的病死率和比例死亡率分别为 7.38%（95%CI95%：6.45-8.42）和 14.11%（95%CI95%：12.4-16.0）。多变量分析显示，年龄<25 岁或 25-40 岁的患者（OR=27.49，95%CI95%：15.28-49.64 和 OR=59.42，95%CI95%：32.76-107.77）、社会经济地位较低或中等的患者（OR=35.03，95%CI95%：21.32-57.56 和 OR=14.11，95%CI95%：10.86-18.43）、学生（OR=2.91，95%CI95%：1.57-5.43）和居住在农村地区的患者（OR=4.12，95%CI95%：3.27-5.19）自杀未遂的风险较高。自杀未遂的发生率随时间的推移呈递增趋势，这引起了严重关注。应努力克服引发自杀未遂的上述危险因素。
