个人可能会根据对健康行为的益处的评估，与其他无法控制的健康威胁相比，做出不从事健康行为的理性决定。预期存活率是感知到对健康的不可控制的威胁的一个标志。我们假设更高的预期生存率：a）与更健康的行为模式具有横断面相关性; B）增加随访时行为比基线时更健康的概率; c）降低随访时行为比基线时“不健康”的概率。来自英国老龄化纵向调查第1和第5波的数据提供了8年的随访。使用预期生存率来测量基线时对不可控制的健康威胁的感知。考虑的健康行为是自我报告的吸烟，身体活动水平和饮酒频率。广泛的社会经济，人口统计和健康变量进行了调整。更高的预期生存率与吸烟的可能性较低和体力活动水平较高有关，但与饮酒无关。较低的预期生存率与采用更健康的体力活动模式的可能性降低有关，并且在随访时成为吸烟者的可能性增加。预期生存率和饮酒量的变化之间没有关联。我们的假设得到了部分证实，尽管相关性在不同行为之间不一致，并且不存在酒精消费。对无法控制的健康威胁的个人评估可能是吸烟和体育活动的重要决定因素。
Individuals may make a rational decision not to engage in healthy behaviours based on their assessment of the benefits of such behaviours to them, compared to other uncontrollable threats to their health. Anticipated survival is one marker of perceived uncontrollable threats to health. We hypothesised that greater anticipated survival: a) is cross-sectionally associated with healthier patterns of behaviours; b) increases the probability that behaviours will be healthier at follow up than at baseline; and c) decreases the probability that behaviours will be ‘less healthy’ at follow than at baseline. Data from waves 1 and 5 of the English Longitudinal Survey of Ageing provided 8 years of follow up. Perceptions of uncontrollable threats to health at baseline were measured using anticipated survival. Health behaviours considered were self-reported cigarette smoking, physical activity level, and frequency of alcohol consumption. A wide range of socio-economic, demographic, and health variables were adjusted for. Greater anticipated survival was cross-sectionally associated with lower likelihood of smoking, and higher physical activity levels, but was not associated with alcohol consumption. Lower anticipated survival was associated with decreased probability of adopting healthier patterns of physical activity, and increased probability of becoming a smoker at follow up. There were no associations between anticipated survival and change in alcohol consumption. Our hypotheses were partially confirmed, though associations were inconsistent across behaviours and absent for alcohol consumption. Individual assessments of uncontrollable threats to health may be an important determinant of smoking and physical activity.
