目标。通过生活取向测试测量的性格乐观与各种健康结果有关。我们评估了乐观情绪是否与健康老龄化指数有关，以及是否通过健康行为来调节影响。从全科医生名单中招募了128名年龄在65岁至80岁之间的男性和女性的社区样本。采用问卷调查的方式对乐观情绪和健康行为进行评估，并用简明健康评定量表的身体健康总分和自评健康状况作为健康老龄化的指标。乐观与不吸烟、适度饮酒、快步行走和剧烈体育活动(仅限女性)相关，与社会人口因素和临床状况无关。身体健康状况与乐观有关，与社会人口因素、临床状况、消极情感和体重无关。当考虑到健康行为时，这种影响会减弱。自我评估的健康状况也与乐观情绪呈正相关，而且这种关联并不是由健康行为来调节的。生活定向量表中的乐观和悲观两个分量表与总量表的效果均不一致。我们的结论是，性格乐观与健康的衰老有关。乐观主义和健康老龄化之间的关系只有一部分是通过本样本中评估的健康行为来调节的。
Objective. Dispositional optimism measured with the Life Orientation Test has been associated with a variety of health outcomes. We assessed whether optimism was related to indices of healthy ageing, and if effects were mediated through health behaviours.Method. A community sample of 128 men and women aged 65 to 80 years was recruited from general practice lists. Optimism and health behaviours were assessed by questionnaire, and healthy ageing indexed by physical health summary scores from the Short Form 36, and by self-rated health.Results. Optimism was associated with not smoking, moderate alcohol consumption, brisk walking, and vigorous physical activities (women only), independently of socio-demographic factors and clinical condition. Physical health status was associated with optimism, independently of socio-demographic factors, clinical condition, negative affectivity, and body mass. This effect was attenuated when health behaviours were taken into account. Self-rated health was also positively related to optimism, and this association was not mediated by health behaviours. Neither the optimism nor pessimism subscales of the Life Orientation Test showed as consistent effects as the full scale.Conclusions. We conclude that dispositional optimism is associated with healthy ageing. The relationship between optimism and healthy ageing was only partly mediated by the health behaviours assessed in this sample.
