Changes in blood pressure (BP) and associated factors which occur on migration from a rural to an urban environment are under observation in a longitudinal study. Blood pressures, heart rate (HR), urinary electrolytes, sociological and anthropometric data are recorded at 0, 3, 6, 12, 18 and 24 months following migration and compared with a cohort of age and sex-matched rural based controls. Data from the first 6 months' follow-up reveal that the migrants' BPs are higher and tend to rise compared with controls, in whom BP falls progressively with time. Changes in body weight and dietary electrolytes appear to explain some of the BP differences, while differences in pulse rates between groups suggest that a further mechanism operative through the autonomic nervous system is responsible for some of the elevation of systolic BP shown amongst migrants, particularly on arrival in the urban area.
一项纵向研究正在观察从农村迁移到城市环境时血压（BP）的变化以及相关因素。在迁移后的0、3、6、12、18和24个月记录血压、心率（HR）、尿电解质、社会学和人体测量数据，并与一组年龄和性别匹配的农村对照人群进行比较。前6个月随访的数据显示，与对照组相比，移民的血压更高且有上升趋势，而对照组的血压随时间逐渐下降。体重和饮食电解质的变化似乎可以解释部分血压差异，而两组之间脉搏率的差异表明，通过自主神经系统起作用的另一种机制导致了移民中观察到的收缩压升高，尤其是在刚到达城市地区时。
