To the Editor We read with interest the recent article titled “Dietary Sodium Content, Mortality, and Risk for Cardiovascular Events in Older Adults: The Health, Aging, and Body Composition (Health ABC) Study” by Kalogeropoulos et al1 published in your journal. Based on a 10-year prospective cohort study consisting of 2642 older adults aged 71 to 80 years, the authors found that higher dietary sodium (>2300 mg/d) was not statistically associated with 10-year mortality, incident cardiovascular disease (CVD), or incident heart failure (HF), compared with normal sodium intake (1500-2300 mg/d). However, the conclusions by Kalogeropoulos et al should be interpreted with caution because of several limitations of the study.
