Suicide rates increase in late life. There is, however, a gap in understanding suicide in the very old. We aimed to underscore the evidence for high rates of death by suicide in the oldest-old men (age 85+) in New Zealand and to provide a conjectural discussion about factors driving these rates.
Provisional suicide data were obtained from the New Zealand Coronial Services website for the period 2011-2019. Yearly suicide rates for those aged 85+ were plotted over time. Mean suicide rates were calculated for three youth and young adult male cohorts, identified by the Coroner as having very high rates, and compared with the 85+ age cohort.
Between 2011 and 2019, rates of death by suicide of older males remained consistently high never overlapping female suicide rates. Mean suicide deaths/100,000 population for all four age cohorts were comparable; 15-19 years: 23.5; 20-24 years: 29.0; 25-29 years: 27.0; 85+ years: 27.9.
Deaths by suicide are very high for older males. In addition to established risk factors, psychosocial adversity as reflected by loneliness, poverty and shift to residential care may be major reasons for the high suicide rates. Research to inform about this vulnerable population and prevention are urgently needed.
自杀率在晚年增加。然而,人们对非常高龄人群的自杀问题仍存在理解上的差距。我们旨在强调新西兰最年长的男性(85 岁以上)自杀死亡率高的证据,并对导致这些死亡率的因素进行推测性讨论。
从新西兰验尸官服务网站获得 2011 年至 2019 年期间的临时自杀数据。逐年绘制 85 岁以上人群的自杀率。计算了三名被验尸官确认为自杀率极高的青年和年轻成年男性队列的平均自杀率,并与 85 岁以上年龄组进行了比较。
在 2011 年至 2019 年期间,老年男性的自杀死亡率一直居高不下,从未与女性自杀率重叠。四个年龄组的平均自杀死亡人数/每 10 万人相当;15-19 岁:23.5;20-24 岁:29.0;25-29 岁:27.0;85 岁以上:27.9。
老年男性的自杀死亡人数非常高。除了已确立的风险因素外,孤独、贫困和转向居住护理所反映的心理社会逆境可能是导致高自杀率的主要原因。迫切需要研究这一弱势群体并开展预防工作。
