Blood pressure, diet, urinary electrolyte excretion, and body form were studied in 264 traditional nomadic herdsmen of the Qash'qai tribe, southern Iran. The population sample included male and female members over 14 yr of age at six winter campsites. Interviews established biological age, any experience of nonnomadic living, and 24-h dietary recall. Height, weight, triceps skinfolds, and blood pressure were measured. Overnight urine samples were analyzed for sodium, potassium, and creatinine. Samples of dietary staples were analyzed for selected nutrients and electrolyte content. Urinary sodium excretion averaged 186 mEq/24 h in males, and 141 mEq/24 h in females. Urinary Na/K ratios were 3.64 and 3.24 in males and females, respectively. Systolic, diastolic, and mean blood pressure in both males and females increased significantly with age. Blood pressure greater than or equal to 140/90 was found in 12% of males and 18% of females age 30 yr or over. Body weight showed no tendency to increase with age in either sex. Systolic and mean blood pressure correlated with urinary sodium excretion in males and with urinary Na/K ratio in females. From cultural observations, the population sample was considered to be at a low level of acculturation. The data suggest that blood pressure trends in this population are related to habitual dietary electrolyte intake.
对伊朗南部卡什卡伊部落的264名传统游牧牧民的血压、饮食、尿电解质排泄和体型进行了研究。该人群样本包括六个冬季营地中14岁以上的男性和女性成员。通过访谈确定了生理年龄、任何非游牧生活经历以及24小时饮食回忆。测量了身高、体重、肱三头肌皮褶厚度和血压。对过夜尿液样本进行钠、钾和肌酐分析。对饮食主食样本进行选定营养素和电解质含量分析。男性尿钠排泄平均为186 mEq/24小时，女性为141 mEq/24小时。男性和女性的尿钠/钾比值分别为3.64和3.24。男性和女性的收缩压、舒张压和平均血压均随年龄显著升高。在30岁及以上的男性中，12%的人血压大于或等于140/90，女性中这一比例为18%。无论男女，体重均无随年龄增加的趋势。男性的收缩压和平均血压与尿钠排泄相关，女性与尿钠/钾比值相关。从文化观察来看，该人群样本被认为文化适应程度较低。数据表明，该人群的血压趋势与习惯性饮食电解质摄入量有关。
