The study aimed to assess the prevalence and associated factors of suicidal behaviour (SB) among adults in Malawi. Data were analysed from 4187 persons aged 18–69 years (median age: 32 years) that took part in the nationally representative cross-sectional “2017 Malawi STEPS survey.” The prevalence of ever suicide attempt was 0.8%, and the prevalence of SB (ideation, plan and/or attempt) in the past year was 7.9% (6.0% among men and 9.6% among women). In adjusted logistic regression analysis, among men, being 30 years and older and having an alcohol family problem were positively and obesity was negatively associated with SB in the past year. Moreover, in univariate analysis, early smoking initiation was positively and not using active transportation was negatively associated with SB in the past year. Among women, having an alcohol family problem, death from suicide of a close family member, having a cardiovascular incident (heart attack, stroke, or angina) and not using active transportation increased the odds of SB in the past year. In addition, in univariate analysis, low systolic blood pressure (< 100 mmHg), not taking antihypertensive medication, and current alcohol use were associated with past year SB. Almost one in ten participants engaged in SB in the past year and several associated factors were identified that can inform intervention programmes.

马拉维成年人自杀行为的流行率和相关性：2017 年具有全国代表性的横断面调查

该研究旨在评估马拉维成年人自杀行为 (SB) 的患病率和相关因素。对参与具有全国代表性的横断面“2017 年马拉维 STEPS 调查”的 4187 名 18-69 岁（中位年龄：32 岁）的数据进行了分析。曾经自杀未遂的发生率为 0.8%，过去一年中 SB（构思、计划和/或企图）的发生率为 7.9%（男性为 6.0%，女性为 9.6%）。在调整后的逻辑回归分析中，在过去一年中，男性中，年龄在 30 岁及以上且有酒精家庭问题的人与肥胖呈正相关，肥胖与 SB 呈负相关。此外，在单变量分析中，在过去一年中，早期吸烟与不使用主动运输与 SB 呈正相关，而与 SB 呈负相关。在有酗酒家庭问题的女性中，在过去的一年中，因近亲自杀、心血管事件（心脏病发作、中风或心绞痛）和不使用主动运输而死亡的情况增加了 SB 的几率。此外，在单变量分析中，低收缩压 (< 100 mmHg)、未服用抗高血压药物和当前饮酒与过去一年的 SB 相关。几乎十分之一的参与者在过去一年中参与了 SB，并确定了一些可以为干预计划提供信息的相关因素。目前饮酒与过去一年的 SB 相关。几乎十分之一的参与者在过去一年中参与了 SB，并确定了一些可以为干预计划提供信息的相关因素。目前饮酒与过去一年的 SB 相关。几乎十分之一的参与者在过去一年中参与了 SB，并确定了一些可以为干预计划提供信息的相关因素。
