The objective of study was to assess 24-h urinary Na and K excretion and estimate the average salt and K intakes in a nationally representative sample of the adult population of Slovenia.
A nationally representative cross-sectional study was conducted in four stages between September and November 2022: study questionnaire, physical measurements, 24-h urine collection and laboratory analysis.
Slovenia.
We invited 2000 adult, non-institutionalised inhabitants of Slovenia, aged between 25 and 64 years. A stratified two-staged sample was selected from this population by the Statistical Office of Slovenia, using sampling from the Central Population Register. According to the WHO methodology, additional eligibility criteria were screened before participating. A total of 518 individuals participated in all four stages of the study, resulting in a response rate of 30 %.
The mean 24-h urinary Na excretion was 168 mmol/d (95 % CI 156, 180), which corresponds to a mean estimated intake of 10·3 g salt/d (95 % CI 9·6, 11·1). Mean 24-h urinary K excretion was 65·4 mmol/d (95 % CI 63·2, 67·5), and the estimated mean K intake was 2·93 g/d (95 % CI 2·84, 3·03). There were statistically significant differences in mean intakes between males and females. The mean sodium-to-potassium ratio was 2·7 (95 % CI 2·5, 2·8).
The study results highlighted that the salt intake in the adult population of Slovenia remains much higher than recommended by the WHO, and K intakes are insufficient, as most participants did not meet the recommendations.
本研究的目的是评估24小时尿钠和钾排泄情况，并估算斯洛文尼亚成年人口全国代表性样本中的平均盐和钾摄入量。
2022年9月至11月分四个阶段进行了一项全国代表性的横断面研究：研究问卷、体格测量、24小时尿液收集和实验室分析。
斯洛文尼亚。
我们邀请了2000名年龄在25至64岁之间、未被机构收容的斯洛文尼亚成年居民。斯洛文尼亚统计局从该人群中通过中央人口登记册抽样选取了一个分层两阶段样本。根据世界卫生组织的方法，在参与前筛选了其他入选标准。共有518人参与了研究的所有四个阶段，应答率为30%。
24小时尿钠排泄均值为168 mmol/d（95%CI 156，180），相当于估计平均盐摄入量为10.3 g/d（95%CI 9.6，11.1）。24小时尿钾排泄均值为65.4 mmol/d（95%CI 63.2，67.5），估计平均钾摄入量为2.93 g/d（95%CI 2.84，3.03）。男性和女性的平均摄入量存在统计学显著差异。钠钾比均值为2.7（95%CI 2.5，2.8）。
研究结果突出表明，斯洛文尼亚成年人口的盐摄入量仍远高于世界卫生组织的建议，钾摄入量不足，因为大多数参与者未达到建议水平。
