Description of Collaborative Activity: |
Because of the logistic complexity, high respondent burden, and high cost of conducting 24-hour urine collections in national surveys, alternative strategies to monitor sodium intake at the population level need to be evaluated. This study is designed to assess the ability to characterize population sodium intake from one or more timed-spot urines calibrated to a 24-hour urine collection. NHLBI convened a working group in 2011 to advise us on the design of the study. One of two studies was conducted in 2012 in younger adults and led by CDC. The second study in older adults is planned for 2013 and will be led by NHLBI. Several manuscripts authored by CDC and NIH staff based on the first study are in preparation or have been submitted. |
