Suicidal behavior and its correlates remain relatively understudied in pregnant teenagers.
A cross-sectional study with a consecutive sample of pregnant teenagers recipient of prenatal medical assistance by the national public health system in the urban area of Pelotas, southern Brazil. Sample size was estimated in 871 participants. Suicidal behavior and psychiatric disorders were assessed with the Mini International Neuropsychiatric Interview; the Abuse Assessment Screen was used to identify physical or sexual abuse; social support was assessed with the Medical Outcomes Survey Social Support Scale; a self-report questionnaire was used to collect socio-demographic, obstetric and other psychosocial data.
Forty three (4.94%) teenagers refused to participate, resulting in 828 participants. Prevalence of suicidal behavior was 13.3%; lifetime suicide attempts were referred by 7.4%, with 1.3% reporting attempting suicide within the last month. After adjustment, we found significant associations of suicidal behavior with the 18-19 years old subgroup, low education, prior abortion, previous major depression, and physical abuse within the last 12 months. Pregnant teenagers with high social support showed prevalence ratios (PR) 67% lower (PR: 0.33; 95%CI: 0.19-0.56) than those with low social support. Furthermore, a wide range of psychiatric disorders, most notably major depressive disorder (PR: 2.75; 95%CI: 1.34-5.63) and panic disorder (PR: 6.36; 95%CI: 1.61-25.10), remained associated with suicidal behavior after adjustment.
The cross-sectional design precludes causal inferences.
We found that suicidal behavior is a relatively common feature in pregnant teenagers, frequently associated with psychiatric disorders.
自杀行为及其相关因素在孕妇青少年中研究相对较少。
这是一项横断面研究，采用连续样本，研究对象为在巴西南部皮拉塔斯市接受国家公共卫生系统产前医疗救助的孕妇青少年。根据 871 名参与者估计样本量。使用 Mini 国际神经精神访谈评估自杀行为和精神障碍；使用虐待评估筛查工具识别身体或性虐待；使用医疗结果调查社会支持量表评估社会支持；使用自我报告问卷收集社会人口统计学、产科和其他心理社会数据。
43 名（4.94%）青少年拒绝参与，最终 828 名参与者纳入分析。自杀行为的发生率为 13.3%；终生自杀未遂者占 7.4%，其中 1.3%报告在过去一个月内自杀。调整后，我们发现自杀行为与 18-19 岁年龄组、低教育程度、既往堕胎、既往重度抑郁症和过去 12 个月内身体虐待显著相关。高社会支持的孕妇青少年的自杀行为发生率比值比（PR）低 67%（PR：0.33；95%CI：0.19-0.56）。此外，广泛的精神障碍，尤其是重度抑郁症（PR：2.75；95%CI：1.34-5.63）和惊恐障碍（PR：6.36；95%CI：1.61-25.10），在调整后仍与自杀行为相关。
横断面设计不允许进行因果推断。
我们发现自杀行为在孕妇青少年中较为常见，且常与精神障碍相关。
