SARS and Elderly Suicide (Chan et al, 2006) 非典型肺炎和長者自殺There is an apparent increase insuicide rates in older persons in 2003, which may be related to SARS outbreak
Older people may be more vulnerable :
disruption of health care disruption of social network and
support proneness to exaggerated
pessimism because of high mortality of SARS in older persons
在 2003年,香港長者的自殺率有明顯的增加,這可能與非典型性肺炎爆發有關
長者可能更加脆弱︰
健康護理被擾亂
社交網絡和支持被擾亂
傾向誇大悲觀,因為非典型肺炎在長者中有高死亡率
