Properties of one’s Studies People
The characteristics of the 102,216 participants are shown in Table 1 , and in Tables S2 and S3 in the Supplementary Appendix. Mean sodium excretion was estimated to be 4.93±1.73 g, and mean potassium excretion was estimated to be 2.12±0.60 g, with higher excretion in men than in women (P<0.001 for sodium and potassium).
Models off Sodium and Potassium Excretion
Observed removal from one fasting day pee sample and projected “usual” excretion (immediately after changes having regression dilution bias) are provided. To have observed excretion, the brand new suggest (±SD) salt removal was 4.93±step one.73 g every day; 3.3% away from people had salt excretion out-of lower than dos.30 grams every single day, and you may 0.6% out-of people had salt removal off lower than step one.50 g every single day. To own projected usual removal, the newest mean sodium excretion are 4.90±step 1.17 grams a-day; 0.2% from users got sodium excretion out-of lower than dos.29 grams each day, and nothing got sodium removal out-of below step 1.fifty grams every day.
Overall, 43.5% of the population had an estimated sodium excretion of more than 5 g per day, 45.9% between 3 and 5 g per day, and 10.6% less than 3 g per day (3.3% had an excretion <2.3 g per day, and 0.6% <1.5 g per day). After adjustment for regression dilution bias, 2.1% of participants had an estimated sodium excretion of less than 3 g per day, and only 0.2% had excretion of less than 2.3 g per day ( Figure 1A ). Overall, 7.9% of participants had an estimated potassium excretion of more than 3 g per day ( Figure 1B ).
Estimated sodium excretion was higher in rural areas than in urban areas (P<0.001), whereas estimated potassium excretion was higher in urban areas (P<0.001) (Tables S2 and S3 in the Supplementary Appendix). (more…)
