The relationship between salt intake and blood pressure was explored in three different areas of Northern Kashmir, where people consume large quantities of salt in tea. Six villages were selected from each area and all the available family members of every second or third house were studied. Food and salt were weighed and the intake of each family member was obtained from the amount consumed out of the total cooked. Complete data were available from 361 subjects (191 males, 170 females). There was no significant difference between the three areas as regards age, height, weight, salt intake and blood pressure. Their age ranged from 15 to 88 yrs (mean 44) and the daily salt intake ranged from 70 to 420 mmol (mean 169 mmol). No correlation was found between age and salt intake or weight but there was a significant correlation between age and systolic blood pressure (r = 0.296; P less than 0.01). Both the systolic and diastolic blood pressure correlated significantly with the salt intake with correlation coefficients of 0.385 and 0.318 respectively (P less than 0.001). Multiple regression analyses showed that the significant relationship between salt and blood pressure was unaltered by adjustment for age. Of the 361 subjects, 46 (12.7%) had a blood pressure of 160/95 mmHg or more. This study suggests a similar relationship between habitual salt intake and blood pressure in each of three different areas of Northern Kashmir.
在克什米尔北部三个不同地区探讨了盐摄入量与血压之间的关系，这些地区的人们在茶中大量摄入盐。从每个地区选取了六个村庄，并对每隔一户或三户的所有家庭成员进行了研究。对食物和盐进行称重，并根据煮熟食物总量中消耗的量得出每个家庭成员的摄入量。共有361名受试者（191名男性，170名女性）提供了完整数据。在年龄、身高、体重、盐摄入量和血压方面，这三个地区之间没有显著差异。他们的年龄在15至88岁之间（平均44岁），每日盐摄入量在70至420毫摩尔之间（平均169毫摩尔）。未发现年龄与盐摄入量或体重之间存在相关性，但年龄与收缩压之间存在显著相关性（r = 0.296；P小于0.01）。收缩压和舒张压均与盐摄入量显著相关，相关系数分别为0.385和0.318（P小于0.001）。多元回归分析表明，在对年龄进行调整后，盐与血压之间的显著关系并未改变。在361名受试者中，46名（12.7%）的血压为160/95 mmHg或更高。这项研究表明，在克什米尔北部三个不同地区，习惯性盐摄入量与血压之间存在相似的关系。
