Desafios para a prevenção de suicídios na idade avança

Abstract

Suicide is a major public health concern worldwide at all ages, accounting for over a million deaths each year. It is of especially grave concern, however, in later adulthood. In countries that report such statistics to the World Health Organization suicide rates to rise steadily throughout the life course for both men and women to clear peaks among the oldest old. Currently the world's population over age 80 years is approximately 105 million. The United Nations estimates that by the year 2050 there will be almost 400 million people in this age group. Even as the number of older people grows, the number of younger and middle-aged people will decrease. In Latin America, for example, there are now 10 working aged adults for each person over age 65, a ratio that will drop to 3:1 by 2050. The challenge, therefore, is a sobering one: far greater numbers of people entering that stage of the life cycle in which suicide risk is highest while resources available to help manage their needs are becoming more limited.There are other challenges to effective prevention of suicide in later life. Studies indicate that with increasing age people tend to use more immediately lethal means for self-harm, and implement them with more extensive planning and greater intent to die. Therefore, death is a more common result than at younger ages. The ratio of attempted to completed suicides in the general population is approximately 40:1, and as high as 200:1 in younger adults. Among older people, however, that ratio is between 1:1 and 4:1. These characteristics underscore the need for development of primary prevention strategies that reduce the likelihood of an older person becoming suicidal. They also require aggressive development and implementation of secondary intervention strategies that result in early detection and intervention for seniors with suicidal ideation or a history of attempts.Although rates of attempted suicide in older adults derived from standard surveillance methods appear markedly lower than at younger ages, there are other common behaviors in later life that, while not typically classified as suicidal, may result in death. Examples abound in long term care facilities, such as refusal to eat food or to take one's medications. Are such "indirect self destructive behaviors" truly suicidal, or rather are they expressions of autonomy in settings where the older person may have few other options for controlling his or her environment? How do we make such distinctions? The stakes are high, as they balance the chance of a preventable death against respect for the older person's right to autonomy and self-expression. The phenomenology, correlates and risk factors of self-destructive behaviors in later life, and how they differ among subgroups of the older adult population, require rigorous study.Similar challenges pertain to the understanding of suicidal ideation in older adults. It is critically important, for example, that we gain greater understanding of nuanced distinctions between suicidal ideation and thoughts of one...

Depressão e Comportamento Suicida: Atenção Primária em Saúde

“…Estudos demonstram que, quando pessoas se autoagridem, elas tendem, à medida que aumenta a idade, a usar meios de letalidade mais intensos, e planejam as situações com maior riqueza de detalhes objetivando a morte (Durkheim, 2011;Conwell, 2015;Linden & Barrow, 1997).…”

Suicide: A Public Health Problem in Brazil

“…According to national and international studies, there is at least a ratio of four attempts for each suicide committed in this stage of life [21]. As associated factors, the authors cite, in general, severe depression, social isolation, loss of meaning in life, loss of children and spouses, severe and degenerative diseases, economic and affection deprivation, inactivity, and experiences of violence in the past and current life [2,[22][23][24].…”
