If age is a useful basis for determining a screening policy the benefit of the resulting interventions should vary with age. The choice of the screening age will be such as to maximize the benefit. Data from a study of the screening of elderly people by a Health Visitor produced no evidence to support the choice of 75 as minimum age for screening in primary care. Indeed there was a suggestion that age might be more useful as a maximum rather than a minimum criterion.
如果年龄是确定筛查政策的有用依据，那么由此产生的干预措施的益处应随年龄而变化。筛查年龄的选择应能使益处最大化。一项由健康访视员对老年人进行筛查的研究数据，没有提供证据支持将75岁作为初级保健中筛查的最低年龄。实际上，有迹象表明，年龄作为一个最大而非最小标准可能更有用。
