self-esteem是自我实现需要的意思么？

blood donors are low in self-esteem,low risk takers,and more highly concerned about their health;non-donors tend to be the opposite on all three dismensions.this suggests that market can be segmented using user status.这句话该怎么翻译啊？怎么觉得那三个方面怪怪的？……
谢谢~
恩 我知道是自尊的意思 字典上就是这么解释的……可是在句中的意思这样翻译不通啊~~~~

self-esteem和self-respect的区别？ 心理学上的“自我概念（Self-Concept）”和“自我意识（self-conscious）”是怎么区别的呀？ This is more serious, but it need not be fatal to your self-esteem. “low self-esteem”因该翻译成“缺少自信”还是“自尊心低”？ 关于Self-Deafting(自我挫败型)人格 物理中的self-consistent是指什么？ self-eveident是啥意思？是“不言而喻”之意吗？ self-contained unit 怎么翻译 ,是一个校准仪 真正的自我是意识的自我? esteem和respect的区别？
