背景/目的：评估参与好利获得心脏研究的成年男性样本中的饮食习惯性钠摄入量以及每日钠摄入量与人体测量指数、饮食习惯和高血压之间的关系。 对象/方法：研究人群由参与好利获得心脏研究 2002-2004 年随访检查的 940 名男性组成。测量血压、人体测量指数、生化参数和 24 小时尿液收集中的钠排泄。所选食物的消费频率是通过捕获前一年数据的食物频率调查问卷（FFQ）来估计的。在研究人群的一个亚组中 (n = 138)，通过内源性锂清除率估算钠的排泄分数。结果：通过 24 小时尿排泄估算的膳食钠摄入量为 203 +/- 70 mmol/天。与血压正常和体重正常的个体相比，接受治疗的高血压患者的钠排泄显着降低，而超重/肥胖的参与者的钠排泄则显着升高。此外，在正常体重个体中检测到的负相关性（r = -0.321；P
Background/Objectives: To assess dietary habitual sodium intake and the association between daily sodium intake and anthropometric indices, food habits and hypertension in the sample of adult male population participating in the Olivetti Heart Study.Subjects/Methods: The study population was composed of 940 men participating in the 2002-2004 follow-up examination of the Olivetti Heart Study. Blood pressure, anthropometric indices, biochemical parameters and sodium excretion in a 24-h urine collection were measured. The frequency of consumption of selected foods was estimated by a food frequency questionnaire (FFQ) capturing the previous year data. In a subgroup of the study population (n = 138), the fractional excretion of sodium was estimated by endogenous lithium clearance.Results: Dietary sodium intake estimated by 24 h urinary excretion was 203 +/- 70 mmol/day. Sodium excretion was significantly lower in treated hypertensive patients and higher in overweight/obese participants when compared with normotensive and normal-weight individuals, respectively. In addition, the inverse correlation detected in normal-weight individuals (r = -0.321; P
