Subjects in low socio-economic strata in underdeveloped countries are subjected to considerable adverse influences which may enhance age-related changes in the nervous system. We therefore assessed the presence of ankle jerks and the degree of postural hypotension in two groups, one from the upper socio-economic level (58 subjects) and the other from the lower socio-economic level (56 subjects). All subjects were over 65 years of age. Only 6% had bilateral loss of ankle jerks, with no difference between the groups. Postural hypotension of 30 mmHg or greater was more frequent in the upper socio-economic group, nine out of 58 versus two out of 56 in the lower group. We conclude that there is no relationship in the elderly between social deprivation and certain markers of neurological dysfunction, such as the absence of ankle jerks and postural hypotension. The reasons for a greater frequency of postural hypotension in the higher socio-economic group are unclear.
在不发达国家，社会经济地位较低阶层的人群受到相当大的不利影响，这些影响可能会加剧与年龄相关的神经系统变化。因此，我们评估了两组人群中踝反射的存在情况以及体位性低血压的程度，一组来自社会经济水平较高阶层（58名受试者），另一组来自社会经济水平较低阶层（56名受试者）。所有受试者年龄均超过65岁。只有6%的人双侧踝反射消失，两组之间无差异。体位性低血压30 mmHg或更高在社会经济水平较高的组中更为常见，58人中有9人出现，而社会经济水平较低的组中56人中有2人出现。我们得出结论，在老年人中，社会剥夺与某些神经功能障碍标志物之间没有关系，如踝反射消失和体位性低血压。社会经济水平较高组中体位性低血压发生率较高的原因尚不清楚。
