Abstract

Both sodium intake and sleep have an important effect on cardiovascular health. However, few studies have looked at the association between sodium intake and sleep. Therefore, we analysed the association of sodium intake with sleep quality, sleep duration and nocturnal urination. The data for the present study were obtained from the Kangbuk Samsung Health Study. Study participants were 156 696 working-aged Korean adults (average age 38.0 years ±8.0 in men and 36.0 years ±8.1 in women). They were categorised into five groups by quintile of sodium intake, measured by food frequency questionnaire. Poor sleep quality and short sleep duration were determined by Pittsburgh Sleep Quality Index >5, and sleep duration <7 h, respectively. Nocturnal urination was defined as awakening to urinate more than three times a week. Multivariable adjusted logistic regression analysis was used in calculating the odds ratio (OR) and 95% confidence interval (CI) for poor sleep quality, short sleep duration and nocturnal urination (adjusted OR [95% CI]) across five study groups. In all study participants, increased sodium intake was significantly associated with poor sleep quality (quintile 1: reference, quintile 2: 1.07 [1.04-1.11], quintile 3: 1.12 [1.08-1.16], quintile 4: 1.15 [1.11-1.19] and quintile 5: 1.13 [1.09-1.18]). This pattern of relationship was similarly observed in association of sodium intake with short sleep duration (p for trend <0.001) and nocturnal urination (p for trend <0.001). In gender subgroup analysis, increased sodium intake had a significant association with poor sleep quality and short sleep duration in men and with poor sleep quality and nocturnal urination in women. In conclusion, high sodium intake is associated with an increased likelihood of poor sleep quality, short sleep duration and nocturnal urination.

工作年龄韩国成年人的膳食钠摄入量及其与睡眠时间、睡眠质量和夜间排尿的关系。
钠的摄入和睡眠对心血管健康都有重要影响。然而,很少有研究关注钠摄入与睡眠之间的关系。因此,我们分析了钠摄入量与睡眠质量、睡眠时间和夜间排尿的关系。本研究的数据来自康布克三星健康研究。研究参与者有156人 696名工作年龄的韩国成年人(平均年龄38.0岁 男性为±8.0岁,男性为36.0岁 女性为±8.1岁)。根据食物频率问卷,按钠摄入量的五分之一将他们分为五组。匹兹堡睡眠质量指数>5确定睡眠质量差和睡眠时间短,睡眠时间
